How do you set about putting all the hundreds of tiny parts together? First, no doubt, you’ll examine the illustrations on the box. Then, following the instructions inside shortens the whole process of putting a model together in the best way possible, making no mistakes.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">Even lacking any assembly instructions, you can still manage the task if you already possess a similar model airplane. The first plane’s design can serve as an important guide in assembling any later one. In the exact same way, using a flawless design in nature as a model provides shortcuts to designing technological equipment with the same functions in the most perfect possible manner. Aware of this, most scientists and research and development (R&D) experts study the examples of living things before embarking on any new designs, and imitate the systems and designs that already exist. In other words, they examine the designs God has created in nature and, then inspired, go on to develop new technologies.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">This approach has given birth to a new branch of science: <em>biomimetics</em>, which means the imitation of living things in nature. This new study is being spoken of more and more often in technological circles and is opening up important new horizons for mankind.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">As biomimetics emerges, imitating the structures of living systems, it presents a major setback for those scientists who still support the theory of evolution. From an evolutionist’s point of view, it’s entirely unacceptable for men—whom they regard as the highest rung on the evolutionary ladder—to try to draw inspiration from (much less imitate) other living things which, allegedly, are so much more primitive than they are.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">If more advanced living things take the designs of “primitive” ones as models, that means that we’ll be basing a large part of our future technology on the structure of those so-called lesser organisms. That, in turn, is a fundamental violation of the theory of evolution, whose logic maintains that living things too primitive to adapt to their environments soon became extinct, while the remaining “higher” ones evolved and succeeded.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">Biomimetics, while placing the proponents of evolution in a vicious circle, is expanding by the day and coming to dominate scientific thought. In the light of this, yet another new scientific branch has emerged: biomimicry, or the science of imitating the behavior of living creatures.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">This book considers the advances that biomimetics and biomimicry have made by taking nature as their model. It examines the flawless but hitherto, little noted systems that have existed ever since living things were first created. It also describes how nature’s many varied and highly efficient mechanisms, which baffle the proponents of evolution, are all products of our Lord’s unique creation.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />

</tbody></table><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">Biomimetics and biomimicry are both aimed at solving problems by first examining, and then imitating or drawing inspiration from models in nature.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><a href="" name="1"></a>Biomimetics is the term used to describe the substances, equipment, mechanisms and systems by which humans imitate natural systems and designs, especially in the fields of defense, nanotechnology <a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics_intro.php#dipnot" style="color: #7f0000; text-decoration: none;">1</a>, robot technology, and artificial intelligence (also known as AI, for short).</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">The concept of biomimicry, first put forth by Janine M. Benyus, a writer and scientific observer from Montana, was later taken up and begun to be used by a great many others. One of their accounts describes her work and the whole development of biomimicry:</div><blockquote style="font-family: Geneva, Arial, Helvetica, san-serif;"><div style="text-align: justify;"><a href="" name="2"></a>A naturalist and author of several field guides to wildlife, she visited the laboratories of a number of scientific researchers who are taking a more modest approach to unraveling nature’s secrets. The theme of “biomimicry” is that we have much to learn from the natural world, as model, measure, and mentor. What these researchers have in common is a reverence for natural designs, and the inspiration to use them to solve human problems. <a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics_intro.php#dipnot" style="color: #7f0000; text-decoration: none;">2</a></div></blockquote><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">David Oakey is a product strategist for Interface Inc., one of the firms making use of nature to improve product quality and productivity. On the subject of biomimicry, he has this to say:</div><blockquote style="font-family: Geneva, Arial, Helvetica, san-serif;"><div style="text-align: justify;"><a href="" name="3"></a>Nature is my mentor for business and design, a model for the way of life. Nature's system has worked for millions of years... Biomimicry is a way of learning from nature. <a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics_intro.php#dipnot" style="color: #7f0000; text-decoration: none;">3</a></div></blockquote><div style="font-family: Geneva, Arial, Helvetica, san-serif;"><img height="159" src="http://www.harunyahya.com/books/science/biomimetics/images/image%20(68).gif" style="text-align: right;" width="219" /></div><div style="text-align: justify;"><br />
</div><div style="text-align: justify;">This rapidly expanding concept found favor with scientists, who were able to accelerate their own research by drawing for inspiration on nature’s incomparably flawless models. Scientific researchers working on economic systems and raw materials—in the industrial field in particular—have now joined forces to determine how best to imitate nature.</div><br />
<div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><a href="" name="4"></a>Designs in nature ensure the greatest productivity for the least amount of materials and energy. They’re able to repair themselves, are environmentally friendly and wholly recyclable. They operate silently, are pleasing in aesthetic appearance, and offer long lives and durability. All these good qualities are being taken as models to emulate. As the journal <em>High Country News</em> wrote,<em>“By using natural systems as models, we can create technologies that are more sustainable than those in use today.”</em> <a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics_intro.php#dipnot" style="color: #7f0000; text-decoration: none;">4</a></div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">Janine M. Benyus, author of the book <em>Biomimicry</em>, came to believe in the need for imitating nature by considering its perfections. Following are some of the examples she cites, which led her to defend such an approach:</div><ul style="font-family: Geneva, Arial, Helvetica, san-serif;"><li style="text-align: justify;">Hummingbirds' ability to cross the Gulf of Mexico on less than 3 grams of fuel,</li>
<li style="text-align: justify;">How dragonflies are more maneuverable than even the best helicopters,</li>
<li style="text-align: justify;">The heating and air conditioning systems in termite mounds—in terms of equipment and energy consumption, far superior to those constructed by man,</li>
<li style="text-align: justify;">Bats’ high-frequency transmitter, far more efficient and sensitive than radar systems created by human beings,</li>
<li style="text-align: justify;">How light-emitting algae combine different chemical substances to give off light without heat,</li>
<li style="text-align: justify;">How arctic fish and temperate-zone frogs return to life after being frozen, with the ice doing their organs no harm,</li>
<li style="text-align: justify;">How anole lizards and chameleons change their colors—and how octopi and cuttlefish change both their colors and patterns in a moment—to blend in with their surroundings,</li>
<li style="text-align: justify;">Bees’, turtles’ and birds’ ability to navigate without maps,</li>
<li style="text-align: justify;">Whales and penguins diving underwater for long periods without scuba gear,</li>
<li style="text-align: justify;">How the DNA helix stores information in all living things,</li>
<li style="text-align: justify;">How, through photosynthesis, leaves perform an astounding chemical reaction to create 300 billion tons of sugar every year.</li>
</ul><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">These are just a few examples of the natural mechanisms and designs that create great excitement, and have the potential to enrich a great many areas of technology. As our information accumulates and technological possibilities increase, their potential becomes ever clearer.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">In the 19th century, for example, nature was imitated only for its aesthetic values. Painters and architects of the time, influenced by the beauties of the natural world, duplicated these structures’ external appearance in their own creations. But the deeper one looks into the fine detail, the more astonishing nature’s immaculate order becomes. Gradually, as the extraordinary nature of natural designs and the benefits that their imitation would bring to mankind, natural mechanisms began to be studied more closely—and finally, at the molecular level.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">The emerging materials, structures and machines being developed through biomimetics can be used in new solar cells, advanced robots and future spacecraft. From that perspective, nature’s designs are opening incredibly broad horizons.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div class="baslik2bordo" style="color: #7f0000; font-family: 'Times New Roman', Times, serif; font-style: normal; font-weight: bold; text-align: justify; text-decoration: none;"><span class="Apple-style-span" style="font-size: x-large;">How Will Biomimetics Change Our Lives?</span></div><div class="baslik2bordo" style="color: #7f0000; font-family: 'Times New Roman', Times, serif; font-style: normal; font-weight: bold; text-align: justify; text-decoration: none;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">Our Lord has given us the designs in nature as great blessings. Imitating them, taking them as models will direct mankind toward what is right and true. For some reason, only recently has the scientific community understood that nature’s designs are an enormous resource and that these need to be made use of in daily life.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">A great many authoritative scientific publications accept that natural structures represent a huge resource for showing mankind the way toward superior designs. <em>Nature</em> magazine expresses it in these terms:</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><a href="" name="5"></a>Yet fundamental research on the character of nature’s mechanisms, from the elephant to the protein, is sure to enrich the pool from which designers and engineers can draw ideas. The scope for deepening this pool is still tremendous. <a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics_intro.php#dipnot" style="color: #7f0000; text-decoration: none;">5</a></div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><a href="" name="6"></a>The correct use of this resource will certainly lead to a process of rapid developments in technology. Biomimetics expert Janine M. Benyus has stated that imitating nature will let us advance in a great many fields, such as food and energy production, information storage, and health. As examples, she cites mechanisms inspired by leaves, which work on solar energy; the production of computers that transmit signals the way cells do; and ceramics made to resist breakage by imitating mother-of-pearl. <a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics_intro.php#dipnot" style="color: #7f0000; text-decoration: none;">6</a></div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">Therefore, it’s evident that the Biomimetic Revolution will influence mankind profoundly and let us live in ever greater ease and comfort.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">One by one, today’s developing technologies are discovering the miracles of creation; and biomimetics is only one of the fields that’s putting the extraordinary designs of living things to use as models in the service of mankind.

</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">It’s important that the word “design” be properly understood.

</div><div style="text-align: justify;">Currently, many scientists are studying the structure of natural materials and using them as models in their own research, simply because these structures possess such sought-after properties as strength, lightness and elasticity. For example, the inner shell of the abalone is twice as resistant as the ceramics that even advanced technology can produce. Spider silk is five times stronger than steel, and the adhesive that mussels use to moor themselves to rocks maintains its properties even underwater. <a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics01.php#dipnot" style="color: #7f0000; text-decoration: none;">16</a></div><br />
<div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">Gulgun Akbaba, a member of the Turkish<em> Bilim ve Teknik </em>(Science and Technology) Magazine research and publication group, speaks of the superior characteristics of natural materials and the ways in which we can make use of them:</div><blockquote style="font-family: Geneva, Arial, Helvetica, san-serif;"><div style="text-align: justify;">Traditional ceramic and glass materials have become unable to adapt to technology, which improves almost with every passing day. Scientists are [now] working to fill this gap. The architectural secrets in the structures in nature have slowly begun to be revealed… In the same way that a mussel shell can repair itself or a wounded shark can repair damage to its skin, the materials used in technology will also be able to renew themselves.</div></blockquote><br />
<blockquote style="font-family: Geneva, Arial, Helvetica, san-serif;"><div style="text-align: justify;"><a href="" name="17"></a>These materials which are harder, stronger, more resistant and have superior physical, mechanical, chemical and electromagnetic properties, possess lightness and the ability to withstand high temperatures required by such vehicles as rockets, space shuttles, and research satellites when leaving and entering the Earth’s atmosphere. Work on the giant supersonic passenger carriers planned for intercontinental travel also requires light, heat-resistant materials. In medicine, the production of artificial bone requires materials that combine spongy appearance with hard structure, and tissue as close as possible to that found in nature. <a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics01.php#dipnot" style="color: #7f0000; text-decoration: none;">17</a></div></blockquote><div style="font-family: Geneva, Arial, Helvetica, san-serif;"><img height="160" hspace="5" src="http://www.harunyahya.com/books/science/biomimetics/images/image-(116).jpg" style="text-align: left;" width="156" /></div><div style="text-align: justify;"><br />
</div><div style="text-align: justify;">To produce ceramic, used for a wide range of purposes from construction to electrical equipment, temperatures greater than 1,000-1,500 <sup><span class="Apple-style-span" style="font-size: medium;">o</span></sup>C (1,830-2,730<sup><span class="Apple-style-span" style="font-size: medium;">o</span></sup>F) are generally needed.</div><br />
<div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">Several ceramic materials exist in nature, yet such high temperatures are never used to create them. A mussel, for instance, secretes its shell in a perfect manner at only 4<sup><span class="Apple-style-span" style="font-size: medium;">o</span></sup>C (39<sup><span class="Apple-style-span" style="font-size: medium;">o</span></sup>F). This example of nature’s superior creation drew the attention of Turkish scientist Ilhan Aksay, who turned his thoughts to wondering how we might produce better, stronger, useful and functional ceramics.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif;"><img height="140" src="http://www.harunyahya.com/books/science/biomimetics/images/image-(127).jpg" style="text-align: right;" width="211" /><a href="" name="18"></a></div><a href="" name="18"><div style="text-align: justify;"><br />
</div></a><div style="text-align: justify;"><a href="" name="18">Examining the internal structures of the shells of a number of sea creatures, Aksay noticed the extraordinary properties of abalone shells. Magnified 300,000 times with an electron microscope, the shell resembled a brick wall, with calcium carbonate “bricks” alternating with a protein “mortar.” Despite calcium carbonate’s essentially brittle nature, the shell was extremely strong due to its laminated structure and less brittle than man-made ceramics. Aksay found that its lamination helps keep cracks from propagating, in roughly the same way that a braided rope doesn’t fail when one single strand breaks. </a><a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics01.php#dipnot" style="color: #7f0000; text-decoration: none;">18</a></div><br />

Encouraged by Aksay’s thesis that natural materials’ superior properties stem from connections at the nanometric level (one-millionth of a millimeter), many companies aiming to produce micro-tools at these dimensions have embarked on bio-inspired materials—that is, artificial substances inspired by biological ones. <a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics01.php#dipnot" style="color: #7f0000; text-decoration: none;">20</a></div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />

Natural materials, which can respond to all their needs, also display enormous variety. Therefore, research experts in various fields—from bullet-proof vests to jet engines—imitate the originals found in nature, replicating their superior properties by artificial means.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />

</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">Like all the extraordinary structures, substances and systems in nature, the composites touched on briefly here are each an example of God’s extraordinary art of creation. Many verses of the Qur’an draw attention to the unique nature and perfection of this creation. God reveals the incalculable number blessings imparted to mankind as a result of His incomparable creation:</div><blockquote style="font-family: Geneva, Arial, Helvetica, san-serif;"><div class="ayetler" style="color: black; font-family: Geneva, Arial, Helvetica, san-serif; font-style: normal; font-weight: bold; padding-bottom: 0px; padding-left: 0cm; padding-right: 0px; padding-top: 0px; text-align: justify;">If you tried to number God’s blessings, you could never count them.

</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">The fiberglass technology that began to be used in the 20th century has existed in living things since the day of their creation. A crocodile’s skin, for example, has much the same structure as fiberglass.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">Until recently, scientists were baffled as to why crocodile skin was impervious to arrows, knives and sometimes, even bullets. Research came up with surprising results: The substance that gives crocodile skin its special strength is the collagen protein fibers it contains. These fibers have the property of strengthening a tissue when added to it. No doubt collagen didn’t come to possess such detailed characteristics as the result of a long, random process, as evolutionists would have us believe. Rather, it emerged perfect and complete, with all its properties, at the first moment of its creation.<strong></strong></div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />

Each individual cable is itself a twisted bundle of thinner cables. Each of these thinner cables is itself a twisted bundle of molecules, which are, of course, twisted, helical bundles of atoms. Again and again a mathematical beauty unfolds, a self-referential, fractal kaleidoscope of engineering brilliance. <a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics01.php#dipnot" style="color: #7f0000; text-decoration: none;">25</a></div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />

</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">A layer of fat covers the bodies of dolphins and whales, serving as a natural flotation mechanism that allows whales to rise to the surface to breathe. At the same time, it protects these warm-blooded mammals from the cold waters of the ocean depths. Another property of whale blubber is that when metabolized, it provides two to three times as much energy as sugar or protein. During a whale’s nonfeeding migration of thousands of kilometers, when it is unable to find sufficient food, it obtains the needed energy from this fat in its body.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />

</div><div style="text-align: justify;">Alongside this, whale blubber is a very flexible rubberlike material.

Some 95% of the mother-of-pearl consists of chalk, yet thanks to its composite structure it is 3,000 times tougher than bulk chalk. When examined under the microscope, microscopic platelets 8 micrometers across and 0.5 micrometers thick can be seen, arranged in layers (1 micrometer = 10-6 meter). These platelets are composed of a dense and crystalline form of calcium carbonate, yet they can be joined together, thanks to a sticky silk-like protein. <a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics01.php#dipnot" style="color: #7f0000; text-decoration: none;">27</a></div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><a href="" name="28"></a>This combination provides toughness in two ways. When mother-of-pearl is stressed by a heavy load, any cracks that form begin to spread, but change direction as they attempt to pass through the protein layers.

A second strengthening factor is that whenever a crack does form, the protein layers stretch out into strands across the fracture, absorbing the energy that would permit the cracks to continue. <a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics01.php#dipnot" style="color: #7f0000; text-decoration: none;">28</a></div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />

</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">In contrast to the substances in other living things, vegetable composites consist more of cellulose fibers than collagen. Wood’s hard, resistant structure derives from producing this cellulose—a hard material that is not soluble in water. This property of cellulose makes wood so versatile in construction. Thanks to cellulose, timber structures keep standing for hundreds of years. Described as tension-bearing and matchless, cellulose is used much more extensively than other building materials in buildings, bridges, furniture and any number of items. </div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />

</div></a><div style="text-align: justify;"><a href="" name="29">Because wood absorbs the energy from low-velocity impacts, it’s highly effective at restricting damage to one specific location. In particular, damage is reduced the most when the impact occurs at right angles to the direction of the grain. Diagnostic research has shown that different types of wood exhibit different levels of resistance. One of the factors is density, since denser woods absorb more energy during impact. The number of vessels in the wood, their size and distribution, are also important factors in reducing impact deformation. </a><a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics01.php#dipnot" style="color: #7f0000; text-decoration: none;">29</a></div><br />

</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">Wood consists of parallel columns of long, hollow cells placed end to end, and surrounded by spirals of cellulose fibers. Moreover, these cells are enclosed in a complex polymer structure made of resin. Wound in a spiral, these layers form 80% of the total thickness of the cell wall and, together, bear the main weight. When a wood cell collapses in on itself, it absorbs the energy of impact by breaking away from the surrounding cells. Even if the crack runs between the fibers, still the wood is not deformed. Broken wood is nevertheless strong enough to support a significant load.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />

If we set down all of a spider web’s characteristics, the resulting list will be a very long one. Yet even just a few examples of the properties of spider silk are enough to make the point: <a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics01.php#dipnot" style="color: #7f0000; text-decoration: none;">32</a></div><ul style="font-family: Geneva, Arial, Helvetica, san-serif;"><li style="text-align: justify;">The silk thread spun by spiders, measuring just one-thousandth of a millimeter across, is five times stronger than steel of the same thickness.</li>
<li style="text-align: justify;">It can stretch up to four times its own length.</li>
<li style="text-align: justify;">It is also so light that enough thread to stretch clear around the planet would weigh only 320 grams.</li>
</ul><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">These individual characteristics may be found in various other materials, but it is a most exceptional situation for them all to come together at once. It’s not easy to find a material that’s both strong and elastic. Strong steel cable, for instance, is not as elastic as rubber and can deform over time. And while rubber cables don’t easily deform, they aren’t strong enough to bear heavy loads.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">How can the thread spun by such a tiny creature have properties vastly superior to rubber and steel, product of centuries of accumulated human knowledge?</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />

</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><a href="" name="33"></a>Spider silk’s superiority is hidden in its chemical structure. Its raw material is a protein called keratin, which consists of helical chains of amino acids cross-linked to one another. Keratin is the building block for such widely different natural substances as hair, nails, feathers and skin. In all the substances it comprises, its protective property is especially important. Furthermore, that keratin consists of amino acids bound by loose hydrogen links makes it very elastic, as described in the American magazine <em>Science News</em>: <em>“On the human scale, a web resembling a fishing net could catch a passenger plane.”</em> <a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics01.php#dipnot" style="color: #7f0000; text-decoration: none;">33</a></div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />

The taut cable used on aircraft carriers to halt jets when they land resembles the system that spiders employ. Operating in exactly the same way as the spider’s web, these cables halt a jet weighing several tons, moving at 250 kmph, by absorbing its kinetic energy.</span></td></tr>

</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><a href="" name="34"></a>On the underside of the tip of the spider's abdomen are three pairs of spinnerets. Each of these spinnerets is studded with many hairlike tubes called spigots. The spigots lead to silk glands inside the abdomen, each of which produces a different type of silk. As a result of the harmony between them, a variety of silk threads are produced. Inside the spider’s body, pumps, valves and pressure systems with exceptionally developed properties are employed during the production of the raw silk, which is then drawn out through the spigots. <a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics01.php#dipnot" style="color: #7f0000; text-decoration: none;">34</a></div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">Most importantly, the spider can alter the pressure in the spigots at will, which also changes the structure of molecules making up the liquid keratin. The valves’ control mechanism, the diameter, resistance and elasticity of the thread can all be altered, thus making the thread assume desired characteristics without altering its chemical structure. If deeper changes in the silk are desired, then another gland must be brought into operation. And finally, thanks to the perfect use of its back legs, the spider can put the thread on the desired track.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">Once the spider’s chemical miracle can be replicated fully, then a great many useful materials can be produced: safety belts with the requisite elasticity, very strong surgical sutures that leave no scars, and bulletproof fabrics. Moreover, no harmful or poisonous substances need to be used in their production.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><a href="" name="35"></a>Spiders’ silk possesses the most extraordinary properties. On account of its high resistance to tension, ten times more energy is required to break spider silk than other, similar biological materials. <a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics01.php#dipnot" style="color: #7f0000; text-decoration: none;">35</a></div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">As a result, much more energy needs to be expended in order to break a piece of spider silk of the same size as a nylon thread. One main reason why spiders are able to produce such strong silk is that they manage to add assisting compounds with a regular structure by controlling the crystallization and folding of the basic protein compounds. Since the weaving material consists of liquid crystal, spiders expend a minimum of energy while doing this.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />

Kevlar, the product of our most advanced technology, is made at high temperatures, using petroleum-derived materials and sulfuric acid. The energy this process requires is very high, and its byproducts are exceedingly toxic. Yet from the point of view of strength, Kevlar is much weaker than spider silk.

</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">The thread produced by spiders is much stronger than the known natural or synthetic fibers. But the thread they produce cannot be collected and used directly, as can the silks of many other insects. For that reason, the only current alternative is artificial production.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><a href="" name="36"></a>Researchers are engaged in wide-ranging studies on how spiders produce their silk. Dr. Fritz Vollrath, a zoologist at the university of Aarhus in Denmark, studied the garden spider <em>Araneus diadematus</em> and succeeded in uncovering a large part of the process. He found that spiders harden their silk by acidifying it. In particular, he examined the duct through which the silk passes before exiting the spider's body. Before entering the duct, the silk consists of liquid proteins. In the duct, specialized cells apparently draw water away from the silk proteins. Hydrogen atoms taken from the water are pumped into another part of the duct, creating an acid bath. As the silk proteins make contact with the acid, they fold and form bridges with one another, hardening the silk, which is<em>"stronger and more elastic than Kevlar [. . .] the strongest man-made fiber,"</em> as Vollrath puts it. <a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics01.php#dipnot" style="color: #7f0000; text-decoration: none;">36</a></div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">Kevlar, a reinforcing material used in bulletproof vests and tires, and made through advanced technology, is the strongest manmade synthetic. Yet spider thread possesses properties that are far superior to Kevlar. As well as its being very strong, spider silk can also be re-processed and re-used by the spider who spun it.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">If scientists manage to replicate the internal processes taking place inside the spider—if protein folding can be made flawless and the weaving material's genetic information added, then it will be possible to industrially produce silk-based threads with a great many special properties. It is therefore thought that if the spider thread weaving process can be understood, the level of success in the manufacture of man-made materials will be improved.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />

Yet those machines’ enormous size can’t be compared with the spider’s few cubic millimeters silk-producing organ. Another superior feature of its silk is the way that the spider can recycle it, able to produce new thread by consuming its damaged web.</div>(Adnan Oktar)http://www.blogger.com/profile/07941900256013358025noreply@blogger.com0tag:blogger.com,1999:blog-1620098504704477893.post-68304395021461949522010-06-11T13:01:00.000-07:002010-06-11T13:01:57.285-07:00THE DESIGN IN PLANTS AND BIOMIMETICS<div style="font-family: Geneva, Arial, Helvetica, san-serif; font-size: 12px;"><img align="left" height="300" hspace="5" src="http://www.harunyahya.com/books/science/biomimetics/images/image-(36).jpg" width="278" /><span class="Apple-style-span" style="font-size: medium;"></span></div><div style="text-align: justify;">Fiber-optic technology, which has recently begun to be employed, uses cables capable of transmitting light and high-capacity information.

But in fact, all living things are full of secrets. Asking why and how is enough to let you raise this curtain of familiarity. Anyone who thinks about these questions will realize that everything we see around us is the work of a Creator possessed of reason and knowledge—our All-Powerful Lord. As an example, take the photosynthesis that plants carry out—a miracle of creation, whose mysteries have not yet been uncovered.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">Photosynthesis is the process whereby green plants turn light into carbohydrates that human beings and animals can consume.

The exact nature of these processes is still unclear. Just this feature alone is enough to silence the proponents of the theory of evolution.

<div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><a href="" name="38"></a>Photosynthesis is a rather complicated event and appears impossible to emerge in the organelles within the cell.

In the same way, we store in batteries the energy we obtain from artificial solar panels, which turn light into electrical energy.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">A plant cell’s low power output necessitates the use of a great many “panels,” in the form of leaves. It’s enough for leaves, like solar panels, to face the sun in order to meet human beings’ energy needs. When the chloroplasts’ functions are fully replicated, tiny solar batteries will be able to operate equipment requiring a great deal of energy. Spacecraft and artificial satellites will be able to operate using solar energy alone, with no need for any other energy source.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">Plants, which possess such superior capabilities and astound the scientists who try to imitate them, bow their heads to God, like all other living things.

As a result of this investigation, a German company called ISPO produced a house paint brand-named Lotusan. On the market in Europe and Asia, the product even came with a guarantee that it would stay clean for five years without detergents or sandblasting. <a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics02.php#dipnot" style="color: #7f0000; text-decoration: none;">40</a></div><div style="font-family: Geneva, Arial, Helvetica, san-serif;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif;">Of necessity, many living things possess natural features that protect their external surfaces. There is no doubt, however, that neither the lotus’s external structure nor insects’ chitin layer came about by themselves. These living things are unaware of the superior properties they possess. It is God Who creates them, together with all their features. One verse describes God’s art of creation in these terms:</div><blockquote style="font-family: Geneva, Arial, Helvetica, san-serif;"><div class="ayetler" style="color: black; font-family: Geneva, Arial, Helvetica, san-serif; font-style: normal; font-weight: bold; padding-bottom: 0px; padding-left: 0cm; padding-right: 0px; padding-top: 0px; text-align: justify;">He is God—the Creator, the Maker, the Giver of Form.

On the surface of the lotus leaf, the very cleanest of these, Dr. Barthlott found tiny points, like a bed of nails. When a Speck of dust or dirt falls onto the leaf, it teeters precariously on these points. When a droplet of water rolls across these tiny points, it picks up the speck, which is only poorly attached, and carries it away. In other words, the lotus has a self-cleaning leaf. This feature has inspired researchers to produce a house paint called LOTUSAN, guaranteed to stay clean for five years.

</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">In a field like automobile technology that freely displays the very latest innovations, a simple plant, living in nature since the very first day it came into being thousands of years ago, provided engineers and designers with a source of inspiration. Evolutionists—who maintain that life came about by chance and whose forms developed over time, always moving in the direction of improvement—find this and similar events difficult to accept.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">How can human beings, possessed of consciousness and reason, learn from plants—devoid of any intelligence or knowledge, which cannot even move—and implement what they learn to achieve ever more practical results? The features that plants and other organisms display cannot, of course, be explained away as coincidences. As proofs of creation, they represent a serious quandary for evolutionists.</div><div class="baslik2bordo" style="color: #7f0000; font-family: 'Times New Roman', Times, serif; font-style: normal; font-weight: bold; text-decoration: none;"><br />

</div><div style="font-family: Geneva, Arial, Helvetica, san-serif;">Nearly everyone imagines that plants are unable to combat danger, which is why they easily become fodder for insects, herbivores, and other animals. Yet research has shown that on the contrary, plants use amazing tactics to repel, even overcome their enemies.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif;"><a href="" name="42"></a>To keep leaf-chewing insects at bay, for example, plants sometimes produce noxious chemicals and in a few cases, chemicals to attract other predators to prey on those first ones. Both tactics are no doubt very clever. In the field of agriculture, in fact, efforts are going on to imitate this very useful defense strategy. Jonathan Gershenzon, researching the genetics of plant defenses at Germany’s Max Planck Institute for Chemical Ecology, believes that if this intelligent strategy can be imitated properly, then in the future, non-toxic forms of agricultural pest control could be provided. <a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics02.php#dipnot" style="color: #7f0000; text-decoration: none;">42</a></div><div style="font-family: Geneva, Arial, Helvetica, san-serif;"><img align="right" height="500" hspace="5" src="http://www.harunyahya.com/books/science/biomimetics/images/image-(236).jpg" width="352" /></div><div style="font-family: Geneva, Arial, Helvetica, san-serif;">When attacked by pests, some plants release volatile organic chemicals that attract predators and parasitoids, which lay their eggs inside the living body of pests. The larvae which hatch out inside the pest grow by feeding on the pest from within. This indirect strategy thus eliminates harmful organisms that might damage the crop.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif;">Again, it is by chemical means that the plant realizes that a pest is eating its leaves. The plant gives off such an alarm signal not because it “knows” it’s losing its leaves, but rather as a response to chemicals in the pest species’ saliva. Although superficially, this phenomenon appears to be quite simple, actually quite a number of points need to be considered:</div><div style="font-family: Geneva, Arial, Helvetica, san-serif;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif;">1) How does the plant perceive chemicals in the pest's saliva?<br />
2) How does the plant know that it will be freed from the pest's ravages when it gives off the alarm signal?<br />
3) How does it know that the signal it gives off will attract predators?<br />
4) What causes the plant to send its signal to insects that feed on its assailants?<br />
5) That signal the plant gives off is chemical, rather than auditory. The chemicals employed by insects have a most complex structure. The slightest deficiency or error in the formula, and the signal may lose its efficacy. How is the plant thus able to fine-tune this chemical signal?</div><div style="font-family: Geneva, Arial, Helvetica, san-serif;">No doubt it is impossible for a plant, lacking a brain, to arrive at a solution to danger, to analyze chemicals like a scientist, even to produce such a compound and carry out a planned strategy. Very definitely, indirectly overcoming an enemy is the work of a superior intelligence. That intelligence’s possessor is God, Creator of the plants with all their flawless characteristics and Who inspires them to do what they can to protect themselves.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif;">Therefore, current biomimetic research is making a great effort to imitate the astonishing intelligence that God displays in all living things.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif;"><br />

Among the crops, they growed species that repel stem-borers and attract parasitoids. In such fields, they found, the number of plants infested with stem-borers dropped by more than 80%. Further applications of this incomparable solution observed in plants will make for still further advances. <a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics02.php#dipnot" style="color: #7f0000; text-decoration: none;">43</a></div><div align="justify" style="font-family: Geneva, Arial, Helvetica, san-serif;"><br />

</em></div><div style="font-family: Geneva, Arial, Helvetica, san-serif;"><em>Rossella racovitzae</em>, a species of marine sponge, possesses spicules guiding light as optic fibers do, which of course is employed in the very latest technology. The optical fibers can instantly transport vast amounts of information encoded as light pulses across tremendous distances. Transmitting laser light down a fiber-optic cable makes possible communications unimaginably greater than with cables made of ordinary materials. In fact, a strand no thicker than a hair, containing 100 optical fibers, can transmit 40,000 different sound channels.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif;">This species of sponge which lives in the cold, dark depths of Antarctic seas is easily able to collect the light it requires for photosynthesis thanks to its thorn-shaped protrusions of optical fibers, and is a source of light for its surroundings. This enables both the sponge itself and other living things that benefit from its ability to collect and transmit light to survive. Single-celled algae attach themselves to the sponge and obtain from it the light they need to survive.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif;">Fiber optics is one of the most advanced technologies of recent years. Japanese engineers use this technology to transmit solar rays to those parts of skyscrapers that receive no direct light. Giant lenses sited in a skyscraper’s roof focus the sun’s rays on the ends of fiber optic transmitters, which then send light to even the very darkest parts of the buildings.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif;">This sponge lives at some 100 to 200 meters depth, off the shores of the Antarctic Ocean, under icebergs in what is virtually total darkness. Sunlight is of the greatest importance to its survival. The creature manages to solve this problem by means of optical fibers that collect solar light in a most effective manner.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif;"><br />

Few, however, are aware that there are gearboxes and jet engines in nature, which possess designs far superior to those employed by man.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><a href="" name="47"></a>Gearboxes allow you to change gears in the vehicle so that the motor is used most efficiently. Natural gearboxes work along the same principles as those in cars. Flies, for example, use a natural gearbox that provides three-speed gearshift connected to its wings. Thanks to this system, a fly can instantaneously accelerate or slow down by flapping its wings at the desired speed while in the air. <a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics03.php#dipnot" style="color: #7f0000; text-decoration: none;">47</a></div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">In cars, at least four gears are used to transmit the power from the engine to the wheels. It is possible to drive smoothly only when the gears are used in succession, from low gear to high, and back again. Instead of gears in cars, which are heavy and take up a lot of room, flies have a mechanism that takes up only a few cubic millimeters. Thanks to their far more functional mechanism, flies can beat their wings with ease.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><a href="" name="48"></a>The squid, octopus and nautilus employ a propellant force similar to the principle used by jet engines. To understand just how effective this force is, consider that the species of squid known as <em>Loligo vulgaris</em> can travel in the water at speeds up to 32 kilometers [20 miles] an hour. <a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics03.php#dipnot" style="color: #7f0000; text-decoration: none;">48</a></div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />

The muscles contract, expelling water out of that nozzle at high speed. The animal can reach speeds of up to 32 km (20 miles)an hour to flee predators, sometimes even leaping out of the water and onto the decks of ships.

</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">The nautilus, an incomparable example in this regard, resembles an octopus and may be compared to a ship with a jet engine. It takes water in through a tube beneath its head and then shoots the water out. While the water travels in one direction, the nautilus is propelled in the other.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">Another feature makes scientists envious of these creatures: Their natural jet engines remain impervious to the high pressure of the deep sea. Moreover, the systems that let them move are both silent and extremely light. In fact, the nautilus’ superior design served as a model for submarines.</div><div class="baslik2bordo" style="color: #7f0000; font-family: 'Times New Roman', Times, serif; font-style: normal; font-weight: bold; text-align: justify; text-decoration: none;"><br />

</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">When a submarine fills its ballast tanks with water, the ship becomes heavier than water and sinks toward the bottom. If water in the tanks is emptied out by means of compressed air, then the submarine surfaces. The nautilus employs the same technique. In its body there is a 19-cm (7.48 in) spiral organ rather like a snail’s shell, inside which are 38 interconnected “diving” chambers. To empty out the water; it also needs compressed air—but where does the nautilus find the air it needs?</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">By biochemical means, the nautilus produces a special gas in its body and transfers this gas to the chambers, expelling water from them to regulate its buoyancy. This allows the nautilus to dive or surface when hunting or chased by predators.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />

When these compartments (tanks) are filled with air, the submarine floats. When the air is replaced with water, it sinks. The number of tanks that are filled with water determines the underwater depth at which the submarine runs.</div></td></tr>

</tbody></table><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">Another very important point needs to be considered here. The nautilus has possessed this system, which can withstand the pressure at some 450 meters, since the day it was created. How can it have designed this special structure all by itself? On its own, could the nautilus have developed the gas to obtain the necessary compressed air to empty out the water in its shell? It is definitely impossible for the creature to know how to create the chemical reaction to produce gas, much less build the structures in its body necessary to bring that chemical reaction about, nor to structure a shell capable of withstanding tons of water pressure.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">This superior design is the work of God, Who flawlessly created everything, with no prior models.

In their bodies, bony fish have a swim bladder that gives them their buoyancy. When air is added to the swim bladder, by diffusion through the blood vessels in the bladder walls, the fish becomes less dense overall;when air is removed the fish becomes more dense. By changing the volume of air in the bladder, the fish’s density can be made equal to that of the surrounding water at a given depth.</div></td></tr>

If you possess the necessary technology and knowledge, these rebounding waves can provide a great deal of information about the body they encountered, such as its distance from the source, its size, and the direction and speed of its motion.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">This technology to locate objects by means of sound and pressure waves was developed in the 20th century, actually for military purposes. But today, it is also used to locate sunken ships and for mapping the ocean floor. However, millions of years ago, long before man discovered this technology, living things in nature were using the sound waves they spread around them in order to survive.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">Dolphins, bats, fish and moths have all possessed this system, known as sonar, ever since they were created. What is more, their systems are much more sensitive and functional than those employed by human beings today.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />

</div><div style="font-family: Geneva, Arial, Helvetica, san-serif;"><a href="" name="50"></a>It has long been known that bats use their sonar system to find their way around in the pitch dark. Recently, researchers have uncovered new secrets of how they do it. According to their research, the brown insectivorous bat, <em>Eptesicus fuscus</em>, can process two million overlapping echoes a second. Furthermore, it can perceive these echoes with a resolution of only 0.3 millimeters (1/80th of an inch). According to these figures, bat's sonar is three times more sensitive than its man-made equivalent. <a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics04.php#dipnot" style="color: #7f0000; text-decoration: none;">50</a></div><div style="font-family: Geneva, Arial, Helvetica, san-serif;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif;">Bats' sonar navigational skills teach us a great deal about flying in the dark. Research carried out with infrared thermal imaging cameras and ultrasound detectors afforded considerable information about how bats fly in search of prey at night.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif;">Bats can seize an insect from mid-air as the insect rises from the grass. Some bats even plunge into bushes to capture their prey. It’s no easy task to seize an insect buzzing in the air using only reflected sound waves. But if you consider that the insect is among the bushes, and sound waves bounce back from all the leaves surrounding it, you will grasp what an impressive task the bat actually performs.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif;"><a href="" name="51"></a>In a situation like that, bats reduce their sonar squeals, to prevent their becoming confused by echoes from the surrounding vegetation. Yet by itself, this tactic isn’t enough to enable bats to perceive the objects individually, because they also need to distinguish the arrival time and direction of the overlapping echoes. <a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics04.php#dipnot" style="color: #7f0000; text-decoration: none;">51</a></div><div style="font-family: Geneva, Arial, Helvetica, san-serif;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif;"><a href="" name="52"></a>Bats also use their sonar when flying over water to drink, and in some cases, to capture prey from the ground. Their expert maneuverability can best be seen when one bat chases another. Understanding how they can do this will let us produce a wide range of technological products, especially equipment for sonar navigation and detection. Moreover, bats’ broad-band sonar system is also imitated today in mine-sweeping technology. <a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics04.php#dipnot" style="color: #7f0000; text-decoration: none;">52</a></div><div style="font-family: Geneva, Arial, Helvetica, san-serif;">As we have seen, the properties of living things benefit us in a very large number of ways.

This bat’s sonar system enables it to hunt fish. It’s no exaggeration to think of the bat as a kind of advanced warplane with early warning capabilities. When it locates a fish near the surface of the water, it goes into a dive. On the large feet of the bat, which are ideally designed for seizing fish, there are super sharp, powerful claws. As it approaches its prey, the bat drops its feet below the water, where its thin claws meet no water resistance. These large, sharp and pointed claws give the bat a great advantage when it comes to gripping its prey.

If the bat can't locate the moth, it’s unable to catch it. (Phil Gates, <em>Wild Technology</em>, 53.) The EA-6B Prowler aircraft currently used by the U.S. military imitate these moths’ tactics.

The echoes reflected from the object pass through the dolphin's lower jaw to the middle ear, and from there to the brain. Thanks to the enormous speed at which these data are interpreted, very accurate and sensitive information is obtained.

</div><div style="font-family: Geneva, Arial, Helvetica, san-serif;">As scientific research advances, we are discovering astonishing abilities in living things that offer solutions to problems in many areas of daily life, from the workplace to our hospitals. Darcy Winslow, General Manager of Environmental Business Opportunities for Nike, expresses this truth:</div><blockquote style="font-family: Geneva, Arial, Helvetica, san-serif;"><a href="" name="58"></a>The extent to which the natural world can provide technological solutions for the types of product performance characteristics we must provide are virtually unlimited. Biomimicry still requires exploration, innovation and creativity, but by thinking like or working with a biologist, we must learn to ask a different set of questions and look to nature for inspiration and learning opportunities. <a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics04.php#dipnot" style="color: #7f0000; text-decoration: none;">58</a></blockquote><div style="font-family: Geneva, Arial, Helvetica, san-serif;"><img align="left" height="300" hspace="5" src="http://www.harunyahya.com/books/science/biomimetics/images/image-(111).jpg" width="202" /></div><div style="text-align: justify;">Many firms are now following a strategy that parallels the one that Winslow set out. It is now possible to see electronic and mechanical engineers working together with biologists.</div><br />
<div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">Already, engineers influenced by bat's sonar have mounted a small sonar unit onto a pair of glasses. After a period of familiarization with the glasses, visually handicapped people are now able to avoid obstacles and even ride bicycles. Still, the system’s designers stress that it will never replace human vision eye or be as functional as that of the bat.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">It’s of course impossible for flawless features like this, which even experts have difficulties in replicating, to have appeared by chance. We must not forget that what we refer to here as “features” are actually complex, interconnected systems. The absence or breakdown of only one component means that the whole system fails to work. For example, if bats sent out sound waves but couldn’t interpret the echoes reflected back, they would in fact have no echolocation system at all.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">In scientific literature, the flawless and complete design that living things display is known as “irreducible complexity.” In other words, certain designs become meaningless and functionless if reduced down to a simpler form. Irreducible complexity in all organisms and their systems demolishes the fundamental idea of the theory of evolution, according to which organisms advance gradually, from the simple towards the complex. If a system can serve no purpose before it reaches its final form, there is no logical reason for it to maintain its existence over millions of years, while it refines and completes itself. A species can survive down the generations only if all its systems are present. No components of a system can afford the luxury of hoping to complete their alleged evolution over time. This clearly proves that when living things first appeared on Earth, they were created with all their structures developed and fully formed, as they are today.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">God brought animals and all other living things into being through His superior creation. News of this creation is given in a verse:</div><blockquote style="font-family: Geneva, Arial, Helvetica, san-serif;"><div class="ayetler" style="color: black; font-family: Geneva, Arial, Helvetica, san-serif; font-style: normal; font-weight: bold; padding-bottom: 0px; padding-left: 0cm; padding-right: 0px; padding-top: 0px; text-align: justify;">And He created livestock.

Jose Carmena, of the university’s department of informatics, and his colleagues named this invention “RoBat.” The RoBat was equipped with a central sound source, serving the same function as a bat’s mouth, and two fixed receivers at a distance apart comparable to a bat's ears.</div><div style="text-align: justify;"><br />
</div><br />
<div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">In order to make the best use of echoes, other features of the bat were also borne in mind when designing the RoBat. Bats move their ears to detect interference patterns in the echoes and thus, can easily avoid obstacles in front of them, navigate and hunt down preys. Like bats, the RoBat was also equipped with smart acoustic sensors to make its mechanism as flawless as possible.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">Thanks to such nature-inspired sound sensors, it is hoped that one day our roads will be much safer.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><a href="" name="59"></a>In fact, such car manufacturers as Mercedes and BMW already use ultrasonic sensors to help drivers reverse.

This 10 cm (3.9 in) fish uses its eyes very little in the muddy water. It finds its way by means of the electrical signals constantly given off by muscles in its tail. Under normal circumstances, it emits 300-500 signals a minute. As the pollution levels rise, however, the number of signals emitted per minute can exceed 1,000.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif;"><br />

A water company in the city gave specimens of water from the River Stour to be checked by 20 elephant nose fish. Each fish lives in an aquarium filled with water from the river. The receptor signals in the aquarium are forwarded to computers to which they are linked. If the water is polluted the increased numbers of signals emitted by the fish are identified, and the alarm signal is given by means of the computer. <a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics04.php#dipnot" style="color: #7f0000; text-decoration: none;">60</a></div><table align="center" border="0" cellpadding="5" cellspacing="0" style="font-family: Geneva, Arial, Helvetica, san-serif;"><tbody>

Even today, very few countries have reached that level. Yet some electric eels possess organic radar around their bodies that give off electrical signals that bounce back from its surroundings, letting the animal obtain information about the size, speed and motion of the objects around it. The eel can also obtain information about the gender and maturity of another electric eel, and then invite it to mate or frighten it off. (W. M. Westby, "Les poissons électriques se parlent par décharges," <em>Science et Vie</em>, no. 798, Mar. 1984) Considering the complicated nature of our radar and communications systems, we can better understand the marvelous creation within the eel’s body.</div></td></tr>

</div><div style="text-align: justify;">Which is the most flawless, efficient flying machine? A Skorsky helicopter, a Boeing 747 passenger jet, or an F-16 fighter?</div><br />
<div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><a href="" name="61"></a>The words, beginning a scientific article about birds in <em>Reader's Digest</em>, provide an answer to that question, stating that compared to birds, a marvel of aerodynamics, even the most advanced aircraft are nothing more than crude copies. <a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics05.php#dipnot" style="color: #7f0000; text-decoration: none;">61</a></div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">Birds are perfect flying machines. Any vehicle needs to be fairly light in order to fly. This applies right down to the screws and bolts used to attach the wings. This explains why airplane manufacturers always try to use special materials that are light but also strong and resistant to blows. But despite all the efforts expended toward this goal, we humans are nowhere near birds in this field. Have you ever seen a bird explode or fall apart in mid-air? Or a bird lose a wing because the connections to its body have become weakened?</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />

In a bird's body, however, the air circulation works just like a cooling system. It is therefore impossible to hit a bird with a heat-seeking missile as one can with a plane.</div></td><td><img height="240" hspace="5" src="http://www.harunyahya.com/books/science/biomimetics/images/image-(238).jpg" width="280" /><br />

A bird’s neck allows its beak to reach any part of the body, so that the bird is easily able to maintain its feathers, the most important component of its flight. During flight, the neck also establishes balance, as is the case with the flamingo. Progress made in aeronautics over the past century led to the nose of Concorde, which was able to swivel up and down—a design actually copied from dolphins. </div></td></tr>

As is recorded in early silent movies, in the 19th century some individuals actually tied homemade wings onto their arms and hurled themselves into space, trying to imitate the movements of birds. Predictably, it did not take them long to realize that wings alone were not enough to permit them to fly.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />

According to the findings of researchers at NASA’s Langley Research Center in Virginia, an owl’s flight feathers—unlike most birds, the flight feathers of whose have a sharp, clean edge—have soft fringes that decrease the turbulence, and thus the noise, of air as it flows over wing. Military designers hope that stealth airplanes can be made even stealthier by imitating the owl’s wings. It is hoped that planes now invisible to radar will be completely silent.

On the other hand, straight wings allow greater lift, important for takeoff and landing. The only way of benefiting from both these features is to construct variable-sweep wings, capable of moving backward and forward. (Clive Gifford,<em>Her Yonuyle Ucaklar</em>, (Cutaway Planes) TUBITAK<em>, </em>4th ed., January 1999, 24.) Fighters such as the Tornado and F-111 have just such wings, the sweep of which can be changed in flight.

<div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">Aviation research studies have revealed that when vultures fly, they open their quill feathers—the large feathers at the edge of the wing—like the fingers of a hand. From this observation, researchers thought of taking it as a model to make small metal ailerons and test them in flight. Using these, they hoped it would be possible to reduce the vortexes’ unwelcome effects on a plane by setting up a series of smaller vortexes to replace the large ones that had previously been causing problems.

In order to reveal the flight techniques of fruit flies, Michael Dickinson, a professor in the department of integrative biology at the University of California, Berkeley, and his colleagues constructed a robot, called Robofly. Robofly imitates the insect's flapping motion, but on a 100-fold larger scale and at only a 1,000th of the fly’s speed. It can flap its wings once every five seconds, driven by six computer-controlled motors.<a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics05.php#dipnot" style="color: #7f0000; text-decoration: none;">68</a></div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />

</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">For years, many scientists like Professor Dickinson have been carrying out experiments hoping to discover the details of how insects flap their wings back and forth. During his experiments on fruit flies, Dickinson discovered that insect wings do not merely oscillate up and down, as if attached by a simple hinge, but actually use the most complex aerodynamic techniques. Moreover, the wings change orientation during each flap: The wing’s top surface faces up as the wing moves downwards, but then the wing rotates on its axis so that the underside faces up as the wing rises. Scientists trying to analyze these complex motions say that the conventional steady-state aerodynamics, the approach that works for airplane wings, is insufficient.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><a href="" name="69"></a>Fruit flies actually make use of more than one aerodynamic feature. For example, when they flap their wings, they leave behind them a complicated whirlpool of air currents, rather like the wake of a ship. As the wing reverses direction, it passes back through this churning air, recovering some of the energy lost beforehand. The muscles that allow the fruit fly's only 2.5 mm wings to flap 200 times a second are considered as the most powerful of all insects’ flight muscles.<a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics05.php#dipnot" style="color: #7f0000; text-decoration: none;">69</a></div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />

</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">Dr. John Pearce, of the University of Texas Electrical and Computer Engineering Department, has studied <em>Crotalines</em>, better known as pit vipers<em>.</em></div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><em><br />

</div></a><div style="text-align: justify;"><a href="" name="71">His research focused on the pit organs of these snakes. In front of the snake’s eye is a tiny nerve-rich depression, called the pit, which is used in locating warm-blooded prey. It contains a sophisticated heat-sensing system—so sensitive, in fact, that the snake can detect a mouse several meters away in pitch darkness. </a><a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics06.php#dipnot" style="color: #7f0000; text-decoration: none;">71</a></div><br />

</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><a href="" name="72"></a>The researchers stated that when they unravel the secrets of the pit viper’s search-and-destroy mechanism, the methods the snake employs can be adapted more widely to protect the country from enemy missiles. They hope to develop systems that will help pilots flying dangerous missions avoid enemy weaponry. Dr. Pearce says, <em>“The Air Force wants to see if they can mimic the biological system and get a better missile detector.”</em> <a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics06.php#dipnot" style="color: #7f0000; text-decoration: none;">72</a> But so far, he explains that studies carried out to that end have found it difficult to match the snake’s sensitivity:</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><a href="" name="73"></a>We’re basically modeling the sensitivity of the snake organ. You can measure nerve impulses, but the question is, what do those impulses mean? We use a numerical model to tell us: there’s this much infrared hitting the organ, and that means this many nerve pulses. <a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics06.php#dipnot" style="color: #7f0000; text-decoration: none;">73</a></div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />

</div><div style="text-align: justify;">The snake’s pit is a thin membrane rich in blood vessels and nerve bundles. The membrane is so sensitive, and the variations in the responses so minute and subtle that to catch and study these signals has proved exceedingly difficult. To understand the functioning of the pit organ, it is necessary to work with delicate measurements and photomicrographs.</div><br />

</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">The impressive ability that chameleons have to change colors to match their surroundings is both astonishing and aesthetically pleasing. The chameleon can camouflage itself at a speed that quite amazes people.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><a href="" name="74"></a>With great expertise, the chameleon uses its cells called chromatophores which contain basic yellow and red pigments, the reflective layer reflecting blue and white light, and the melanophores containing the black to dark brown pigment melanin, which darkens its color. <a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics06.php#dipnot" style="color: #7f0000; text-decoration: none;">74</a></div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">For instance, place a chameleon into a bright yellow environment, and it quickly turns yellow. In addition, the chameleon can match not only one single color, but a mixture of hues. The secret behind this lies in the way pigment-containing cells under this master of camouflage’s skin expand or contract to match their surroundings.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><a href="" name="75"></a>Current research under way at Massachusetts Institute of Technology, USA, is aimed at making clothes, bags and shoes able to change colors the same way as the chameleon does. Researchers envision clothing made from the newly developed fiber, which can reflect all the light that hits it, and equipped with a tiny battery pack. This technology will allow the clothing to change colors and patterns in seconds by means of a switch on the pack. <a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics06.php#dipnot" style="color: #7f0000; text-decoration: none;">75</a> Yet this technology is still very expensive.

</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">What would you think if someone showed you a jacket and claimed, “This can change color. Yet nobody prepared the jacket, nor its ability to change color. It all just happened by itself.” Probably you’d imagine that person to be mad or else very ignorant. Quite clearly, there must have been a tailor to put it together, and even before that, engineers to create its ability to change color.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">So, how can the chameleon carry out these impeccable changes? Did it design the systems that permit the change, install them inside its own body, and carry out the processes all by itself? Of course it would be most irrational to claim that the chameleon did this all of its own free will. Since even human beings find it definitely impossible to bring about such a change, how can a reptile install a system capable of changing its own body’s appearance? To claim that such a superior ability came about by chance is nonsensical and invalid.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">No natural mechanism has the power to form such impeccable abilities and bestow them on the living things that need it. A superior power rules the atoms, molecules, and cells in the creature’s body and arranges them as it wishes.

</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">In an article published in<em> American Scientist</em>, the well-known US scientific magazine, Andrew R. Parker states that he and his colleagues examined a mummified fly preserved in amber resin for 45 million years. There was a periodic grating structure on the curved surfaces of the fly ommatidia (individual visual organs composing the fly's compound eye). Analyzing the reflective properties of this structure, they realized that the fly-eye structure was a very efficient antireflector, particularly at high angles of incidence. This hypothesis was indeed confirmed in later studies.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><a href="" name="76"></a>Thanks to these findings and others, today’s scientists have determined how to greatly increase the efficiency of solar absorbers and solar panels used to provide energy for satellites. Work is currently under way to reduce the angular reflection of infrared (heat) and other light waves by mimicking the fly-eye structure. Most suitable for use in solar panel surfaces, the fly-eye grating has also done away with the necessity for expensive equipment to ensure that these panels are always directly facing the Sun. <a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics06.php#dipnot" style="color: #7f0000; text-decoration: none;">76</a></div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">Only recently have space technologists discovered and imitated this design, but flies have possessed it for millions of years. Similar structures have recently been discovered also on some Burgess Shale fossils, 515 million years old. Permitting very acute and color vision, this design shows just what a superior product of creation it really is. But such evidence can be comprehended only by believers—those who can use their reason to comprehend that everything that exists is under God’s control.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">One verse describes how similar proofs mean nothing to those who deny God:</div><blockquote style="font-family: Geneva, Arial, Helvetica, san-serif;"><div class="ayetler" style="color: black; font-family: Geneva, Arial, Helvetica, san-serif; font-style: normal; font-weight: bold; padding-bottom: 0px; padding-left: 0cm; padding-right: 0px; padding-top: 0px; text-align: justify;">God is not ashamed to use the example of a mosquito or of an even smaller thing. As for those who believe, they know it is the truth from their Lord. But as for those who do not believe, they say, “What does God mean by this example?” He misguides many by it and guides many by it. But He only misguides the deviators.

</div><div style="text-align: justify;">In the desert, where few living things are to be found, some species possess the most astonishing designs. One of these is the tenebrinoid beetle <em>Stenocara,</em> which lives in the Namib Desert, in Southern Africa. A report in the November 1, 2001, edition of <em>Nature</em> describes how this beetle collects the water so vital to its survival.</div><br />
<div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><em>Stenocara</em>’s water capture system basically depends on a special feature of its back, whose surface is covered with tiny bumps. The surface of the regions between these bumps is wax-coated, though the peaks of the bumps are wax-free. This allows the beetle to collect in a more productive manner.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><em><a href="" name="77"></a>Stenocara</em> extracts from the air the water vapor that occurs only rarely in its desert environment. What is remarkable is how it separates out the water from the desert air, where tiny water droplets evaporate very quickly due to heat and wind. Such droplets, weighing almost nothing, are borne along parallel to the ground by the wind. The beetle, behaving as if it knew this, tilts its body forwards into the wind. Thanks to its unique design, droplets form on the wings and roll down the beetle's surface to its mouthparts.<a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics06.php#dipnot" style="color: #7f0000; text-decoration: none;">77</a></div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><a href="" name="78"></a>The article about <em>Stenocara</em> included the following comment: <em>“The mechanism by which water is extracted from the air and formed into large droplets has so far not been explained, despite its biomimetic potential.”</em> <a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics06.php#dipnot" style="color: #7f0000; text-decoration: none;">78</a></div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">Examining the features of this beetle’s back under an electron microscope, scientists established that it’s a perfect model for water-trapping tent and building coverings, or water condensers and engines. Designs of such a complex nature cannot come about just by themselves or through natural events. Also, it’s impossible for a tiny beetle to have “invented” any system of such extraordinary design. Just <em>Stenocara</em> alone is sufficient to prove that our Creator designed everything that exists.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />

What force allows fireflies to engage in such a high level of efficiency? According to evolutionists, the answer lies in unconscious atoms, happenstance, or other external factors with no propulsive force; none of which can possess the power to actually initiate such productive activity.

</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">In the high-speed trains developed by the Japanese, safety is one of the most important factors. A second is compatibility with Japanese environmental standards. Japan’s noise regulations regarding railway operators are the strictest in the world. Using current technology, it’s not actually that difficult to go faster, though it’s hard to eliminate noise while doing so. Under Japanese Environment Agency regulations, a railway’s noise levels must not exceed 75 decibels at a point 25 meters (82 feet) away from the center of railway track in urban areas. At a crossing in a town, when cars start to move all at once on the green light, they create more than 80 decibels. This goes to show just how quiet the high-speed Shinkansen train must be.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />

</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">The reason for the noise that a train produces up to a certain operation speed is the rolling of its wheels on the tracks. At speeds of 200 kmph (125 mph) or over, however, the sound source becomes the aerodynamic noise caused by its movement through the air.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif;"><img height="198" hspace="5" src="http://www.harunyahya.com/books/science/biomimetics/images/image-(182).jpg" style="text-align: right;" width="241" /></div><div style="text-align: justify;"><br />
</div><div style="text-align: justify;">The major sources of aerodynamic noise are the pantographs, or current collectors, used to take in electricity from overhead catenary. Engineers, realizing that they couldn’t reduce noise levels with the conventional rectangular pantographs, concentrated their research on animals that move quickly, yet silently.</div><br />
<div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">Of all birds, owls make the least noise during flight. One of the ways they manage this is through the plumes of their wings. In addition, an owl’s wings have many small saw-toothed feathers (serrations) visible even to the naked eye, which other birds lack. These serrations generate small vortexes in the air flow. Aerodynamic noise stems from vortexes forming in the air flow. As these grow in size, the noise increases. Since owls’ wings feature many saw-toothed projections, they form smaller vortexes instead of large ones, and the owls can fly very quietly.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><a href="" name="81"></a>When Japanese designers and engineers tested stuffed owls in a wind tunnel, they once again witnessed the perfection of these birds’ wing design. Later, they succeeded in efficiently reducing train noise by using wing-shaped pantographs based on the principle of the owl’s serrations. Thus the pantograph system developed by the Japanese, inspired by nature, became the quietest functioning. <a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics06.php#dipnot" style="color: #7f0000; text-decoration: none;">81</a></div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />

</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">The tunnels on the lines used by high-speed trains represented another problem for engineers to solve. When a train enters a tunnel at a high speed, atmospheric pressure waves rise up and gradually grow up to be like tidal waves that approach the exit of the tunnel at the same sonic speed. At the exit, the waves then return. At the tunnel’s exit, part of the pressure waves is released with a sometimes explosive noise.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><img height="200" hspace="5" src="http://www.harunyahya.com/books/science/biomimetics/images/image-(233).jpg" style="text-align: left;" width="343" />Since the pressure of the waves is about one thousandth of atmospheric pressure or less, they're referred to as tunnel micro-pressure waves, which form as shown in the diagram.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">The very disturbing noise created under the influence of the pressure waves can be reduced by widening the tunnel, but the task of altering the cross-sectional area of tunnels is very difficult and expensive.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">At first, engineers thought that reducing the cross-sectional area of trains and making the forefront shape sharp and smooth might be a solution. They put these ideas into action in an experimental train, but remained unable to eliminate the micro-pressure waves it created.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">Wondering if similar dynamics arose in nature, the designers and engineers thought of the kingfisher. In order to hunt its prey, the kingfisher dives into water, which has greater fluid resistance than air, and it experiences sudden changes in the resistance like a train does when it enters a tunnel.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif;"><img height="170" src="http://www.harunyahya.com/books/science/biomimetics/images/image-(230).jpg" style="text-align: right;" width="203" /></div><div style="text-align: justify;">Accordingly, a train traveling at 300 kmph (186 mph) needs to have a forefront shape like a kingfisher’s beak, which facilitates the bird’s diving.</div><br />
<div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><a href="" name="82"></a>Studies conducted by the Japanese Railway Technical Research Institute and the University of Kyushu revealed that the ideal shape to suppress tunnel micro-pressure waves was a shape of revolving paraboloid or a wedge. A close-up cross-section of a kingfisher’s upper and lower beak form precisely this shape. <a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics06.php#dipnot" style="color: #7f0000; text-decoration: none;">82</a> The kingfisher is yet another example of how all living things are created with exactly what they need to survive—and whose designs can serve as models for human beings.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />

Just as the bird’s beak facilitates such a dive, it also prevents its body from harm. But the kingfisher still needs to be able to see its prey as it dives into the water. God has created the bird with a protective mechanism to protect its eyes without hindering its ability to see and seize its prey underwater. When one bears in mind the fact that underwater objects appear to be somewhere else than where they really are when one looks at them from above the water, the importance of this becomes even clearer.</span></td></tr>

</div><div style="text-align: justify;">We use computers so extensively that they’ve become part of every moment of our lives 24 hours a day—at home, at work, even in our cars. Computer technology is developing rapidly day by day, and increasing living standards require of computers’ functioning to increase at the same pace, growing faster all the time. The latest models can achieve breathtaking speeds, and faster chips mean that computers can carry out more tasks in less time. However, faster chips lead to greater consumption of electricity, which warms up the chips as a result. It is essential for computer chips to be cooled down to prevent them from melting. The existing fans are no longer sufficient to cool down the latest generation of chips. Designers seeking a solution to this problem eventually declared that they had found a solution in nature. </div><br />
<div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">Butterfly wings contain a perfect structure in their design. Research carried out at Tufts55 University has revealed that there is a cooling system in butterfly wings. When this system is compared to that in computer chips, it has a much better performance. A team headed by assistant research professor of mechanical engineering Peter Wong was funded by the American National Science Foundation to study how iridescent butterflies control heat.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><a href="" name="84"></a>Since butterflies are cold-blooded, they have to constantly regulate their body temperatures. This is a serious problem, because friction during flight leads to considerable quantities of heat. This heat needs to be cooled down at once. Otherwise, the butterfly will not survive. The solution is provided by the millions of microscopic scales, called thin-film structures, clinging to their wings. The heat generated is thus dispersed. <a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics06.php#dipnot" style="color: #7f0000; text-decoration: none;">84</a></div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />

<div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><strong><a href="" id="85" name="85"></a></strong>A July 12, 2001 news release published by America’s Sandia National Laboratories announced that as a result of their work, they had “approached the visual acuity of the eye itself.” The report stated that using 64 computers, a digital image was produced that took them only seconds to acquire. <a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics07.php#dipnot" style="color: #7f0000; text-decoration: none;">85</a></div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">This is a most important development, yet one point shouldn’t be forgotten. In as little as one-tenth of a second, human eyes form an image that takes up no more space than one square millimeter on the retina. With this in mind, it can be seen that the human eye is much faster and more functional than 64 computers, using the very latest technology.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif;"></div><div style="text-align: justify;"><span class="Apple-style-span" style="color: #7f0000; font-family: 'Times New Roman', Times, serif; font-weight: bold;"><br />

<div style="font-family: Geneva, Arial, Helvetica, san-serif;"><img height="200" hspace="5" src="http://www.harunyahya.com/books/science/biomimetics/images/image-(134).jpg" style="text-align: left;" width="149" /><img height="200" hspace="5" src="http://www.harunyahya.com/books/science/biomimetics/images/image-(13).jpg" style="text-align: left;" width="138" /><a href="" name="86"></a></div><a href="" name="86"><div style="text-align: justify;"><br />
</div></a><div style="text-align: justify;"><a href="" name="86">Human beings live for an average of between 70 and 80 years. The human heart beats some 70 to 80 times a minute, for a total of several billion times during the course of an individual’s lifetime. The Abiomed company, known for its research into artificial hearts, has stated that despite all its work, it will be unable to imitate the flawless functioning that the heart displays successfully over the years. For the company’s newly-developed artificial heart to beat 175 million beats, or about five years, appears a significant target. </a><a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics07.php#dipnot" style="color: #7f0000; text-decoration: none;">86</a></div><br />
<div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">A product of the latest technology, this artificial heart was tested in calves before human beings, although the calves survived for only a few months. The artificial heart developed by the company has been put in safety trials in human heart failure patients in 2004. But, obviously researchers find the human heart so difficult to imitate. Steven Vogel of Duke University, a biomechanic who has also written a book on this subject, describes why:</div><blockquote style="font-family: Geneva, Arial, Helvetica, san-serif;"><div style="text-align: justify;"><a href="" name="87"></a>It’s that the engines we have available, whatever their power output or efficiency work so differently. Muscle is a soft, wet, contractile engine, and that’s just unlike anything in our technological armamentarium. So you can’t imitate a heart . . . <a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics07.php#dipnot" style="color: #7f0000; text-decoration: none;">87</a></div></blockquote><div style="font-family: Geneva, Arial, Helvetica, san-serif;"><img height="173" src="http://www.harunyahya.com/books/science/biomimetics/images/image-(257).jpg" style="text-align: right;" width="140" /><a href="" name="88"></a></div><a href="" name="88"></a><div style="text-align: justify;"><a href="" name="88">Like the genuine article, Abiomed’s artificial heart consists of two ventricles. There the similarity ends, however. Alan Snyder of Penn State, a bioengineer who led the research, explains the difference in these terms: “In the natural heart, you’re using muscle as a container and the container pumps on its own.” </a><a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics07.php#dipnot" style="color: #7f0000; text-decoration: none;">88</a> Pumps that work along the same lines as the heart contain a container <em>and</em> a system that pumps the fluid. In the heart, however, the container carries out its own pumping. That is the difference Snyder summarized.</div><br />
<div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">Researchers, wondering how to make a heart that contracts by itself, set the interior walls of the two ventricles into motion by placing a separate engine between them. This artificial heart works with a battery located in the patient’s abdomen. This battery has to be recharged continuously by radio waves emitted by a rechargable battery pack patients will wear in a harness.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><a href="" name="89"></a>Our natural hearts, on the other hand, have no need of a battery for energy, because they boast an incomparable muscular design capable of creating its own energy in every cell. Another feature of the heart that can’t be replicated is the incomparable efficiency of its pulses. In fact, the heart can pump five liters of blood a minute while at rest, which can rise to 25-30 liters during exercise. Kung, Abiomed’s director, describes this extraordinary change of tempo as “a challenge that currently no mechanical device can meet.” The artificial heart made by the company can only pump 10 liters a minute at best, which is not sufficient for a great many ordinary activities. <a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics07.php#dipnot" style="color: #7f0000; text-decoration: none;">89</a></div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">The real heart is nourished and strengthened according to its needs by the blood it pumps. Such a heart can work for 50 to 60 years with no need for repairs. The heart possesses the capacity for self-renewal, which is why it never loses its ability for uninterrupted work. This is yet another feature that makes it impossible to imitate artificially.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">Our heart, which scientists can only dream of matching with present-day technology, shows to us the superior knowledge of our Creator and our Great Lord—God.</div><div class="baslik2bordo" style="color: #7f0000; font-family: 'Times New Roman', Times, serif; font-style: normal; font-weight: bold; text-align: justify; text-decoration: none;"><br />

</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">Once a single computer is affected by a virus, this means that other computers in the world may soon be contaminated as well. Many companies, therefore, have seen it necessary to set up an “immune system” to protect their network systems from viruses and continue to carry out intensive research in this area. One of the centers that is carrying out this work is the virus isolation laboratory at the IBM's Watson Research Center in New York. There, a high-security microbiology laboratory works with lethal viruses, also producing programs that can diagnose the 12,000 or so viruses identified so far—and also isolate the viruses from a computer in a safe manner and then kill them.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">IBM is only one of the firms trying to construct a worldwide immune system to protect its existing computer systems from virus threats in the cyberspace. Steve White, one of the company’s executives, states that to achieve that end, an immune system like the human body’s is needed.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><a href="" name="90"></a>It's only the existence of an immune system that allows the human race to exist. Only an immune system in cyberspace will allow it to exist.<a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics07.php#dipnot" style="color: #7f0000; text-decoration: none;">90</a></div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">Pursuing this analogy between the computer and living things, researchers have begun producing protective programs that function like our own immune systems. They believe what we have learnt from epidemiology (the branch of science which studies contagious diseases) and immunology (which deals with the immune system) will be able to protect electronic programs from new threats in the same way that antibodies protect living organisms. </div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif;"><img height="200" hspace="5" src="http://www.harunyahya.com/books/science/biomimetics/images/image-(29).jpg" style="text-align: left;" width="250" /></div><div style="text-align: justify;"><br />
</div><div style="text-align: justify;">Computer viruses are clever self-replicating programs designed to infiltrate computers, multiply by copying themselves and damage or “hijack” the computers they enter. Indications that such viruses are present include a slowing down of the computer system, occasional mysterious damage to files, and sometimes, complete failure or “crashing” of the computer itself—much as with the various diseases that affect human beings.</div><br />
<div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">To protect our computers against the menace of viruses, identification programs search every code in the computer’s memory to find traces of viruses that have previously been identified and stored in the programs’ memory. Computer viruses carry traces of the signature of the software writer that let them be recognized. When the computer’s search program recognizes that telltale signature, it warns that the computer has been infected with a virus.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">Even so, anti-virus programs can’t offer complete protection for computers. Some programmers can write new viruses within a matter of a few days and again insert them into cyberspace through just one infected computer. That being the case, it’s vital that anti-virus programs be constantly updated so that they have the information they need to recognize new viruses. New anti-virus programs need to be added constantly, therefore, to protect against the virus threat.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">With the increasing spread of worldwide use of the Internet, these viruses have begun to spread very much faster and to inflict serious harm to infected computers. IBM researchers have found solutions by imitating natural examples. First of all, just like biological viruses in nature, artificial computer viruses use the host programming to multiply. Starting from that analogy, researchers investigated how the human immune system works to protect the body.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">When it encounters a foreign organism, the body immediately begins to build antibodies that will recognize the invader and destroy it. The immune system doesn’t need to analyze the whole of a cell that might result in a sickness. Once any preliminary infection has been suppressed, the body keeps a number of the appropriate antibodies in readiness, to respond immediately to any future recurrence. Thanks to these standby antibodies, there is no need to examine the entire infected cell. Similarly, existing anti-virus programs also contain an "antibody" that recognizes not the whole computer virus, but rather its signature.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">As we have seen, the solutions to many problems in the technical arena that leave us floundering already exist in nature. Our immune system, of which every detail has been thought out and which functions perfectly, was ready to protect us before we were even born. It is Our Lord Who watches and protects all. In one verse it is revealed:</div><blockquote style="font-family: Geneva, Arial, Helvetica, san-serif;"><div class="ayetler" style="color: black; font-family: Geneva, Arial, Helvetica, san-serif; font-style: normal; font-weight: bold; padding-bottom: 0px; padding-left: 0cm; padding-right: 0px; padding-top: 0px; text-align: justify;">My Lord is the Preserver of everything.

</div><div style="text-align: justify;">The eyes of vertebrates resemble spheres with openings called pupils through which light enters. Behind the pupils are lenses. Light passes first through these lenses, then through the fluid that fills the eyeball, finally striking the retina. In the retina there are some 100 million cells known as rods and cones. The rod cells distinguish between light and dark, and the cones detect colors. All these cells turn the light falling onto them into electrical signals and send them to the brain via the optic nerve.</div><br />
<div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">The eye regulates the intensity of the light entering it by means of the iris, surrounding the pupil. The iris is able to expand and contract, thanks to its tiny muscles. Similarly, the amount of light entering a camera is restricted by a device known as a diaphragm. In his book <em>Wild Technology</em>, Phil Gates describes how the camera is a very simple copy of the eye:</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><a href="" name="91"></a>Cameras are primitive, mechanical versions of vertebrate eyes. They are light-proof boxes equipped with a lens to focus an image on film that is briefly exposed when a shutter is opened. In eyes the image is focused by changing the shape of the lens, but cameras are focused by changing the distance of the lens from the film. <a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics07.php#dipnot" style="color: #7f0000; text-decoration: none;">91</a></div><div class="baslik2bordo" style="color: #7f0000; font-family: 'Times New Roman', Times, serif; font-style: normal; font-weight: bold; text-align: justify; text-decoration: none;"><br />
</div><div class="baslik2bordo" style="color: #7f0000; font-family: 'Times New Roman', Times, serif; font-style: normal; font-weight: bold; text-align: justify; text-decoration: none;"><span class="Apple-style-span" style="font-size: x-large;">Focusing</span></div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">This is the first step in taking a photograph. The same kind of focusing of an image is also necessary in order for it to fall clearly onto the sensitive retina in the eye. With cameras, this is done by hand or automatically in more sophisticated models. Microscopes and telescopes, used to see up close and far away, can also be focused, yet this process always involves a certain loss of time.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">The human eye, on the other hand, performs this process constantly by itself, and very quickly. Furthermore, the method it employs is so superior that it cannot possibly be imitated. Thanks to the muscles around it, the lens sends the image onto the retina. Very flexible, this lens easily changes shape, sharpening the point on which light falls by expanding or contracting.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">If the lens didn’t do this automatically—for instance, if we had to consciously focus on the object of our attention—then we’d have to make a constant effort to be able to see. Images in our sight would blur in and out of focus. We would require time to see anything properly and as a result, all of our actions would be slowed down.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">Because God has made our eyes flawless, however, we experience none of these difficulties. When he wants to see anything, no one has to wrestle with setting his eyes’ focus and make various optical calculations. In order to see an object clearly, it is sufficient to look at it. The rest of the process is handled automatically by the eye and the brain—moreover, it all takes place in the space of time it takes to wish to do it.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div class="baslik2bordo" style="color: #7f0000; font-family: 'Times New Roman', Times, serif; font-style: normal; font-weight: bold; text-decoration: none;"><img height="180" src="http://www.harunyahya.com/books/science/biomimetics/images/image-(101).jpg" style="text-align: right;" width="259" /></div><div style="text-align: justify;"><br />

<div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">A photograph taken in the daytime will be very clear, but not when the same film is used to take a picture of the night sky. Yet even though our eyes open and close in less than one-tenth of a second, we can see the stars quite clearly, because our eyes automatically set themselves according to various intensities of light. Muscles around the pupil allow this to happen. If our surroundings are dark, these muscles expand, the pupil widens and more light is allowed into the eye. With plenty of light, the muscles contract, the pupil shrinks and less light is permitted to enter. That is why we enjoy clear vision both night and day.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />

</div><div style="text-align: justify;">The eye “snaps” both a black-and-white picture and a colored one at the same time. These two pictures are later combined in the brain, where they take on a normal appearance, in much the same way as four-color photography combines black with red, yellow, and blue to produce a realistic full-color image.</div><br />
<div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">The rod cells in the retina perceive objects in black and white, but in a detailed manner. The cone cells identify the colors. As a result, the signals received are analyzed, and our brains form a colored image of the outside world.</div><div class="baslik2bordo" style="color: #7f0000; font-family: 'Times New Roman', Times, serif; font-style: normal; font-weight: bold; text-decoration: none;"></div><div style="text-align: justify;"><br />
</div><div style="text-align: justify;"><span class="Apple-style-span" style="font-size: x-large;">The Eye’s Superior Technology</span></div><br />
<div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">Compared with the eye, cameras possess a very primitive structure. Visual images are many times more precise than those obtainable with even the most highly developed camera. As a result, images perceived by the eye are of much higher quality than those provided by any man-made equipment.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">This whole idea can be better grasped if we examine the principles of a TV camera, which operates by transmitting numerous dots of light. During broadcast, a scanning procedure is applied, and the object before the camera is thus divided into a specific number of lines. A photocell lamp scans all the dots in each line consecutively, from left to right. Having finished scanning one line, it moves on to the next, and the process continues. The light values of each dot are analyzed, and the resulting signal is emitted. This photocell scans 625 or 819 lines in one-twenty fifth of a second. When one entire image is complete, a new one is transmitted. In this way the quantity of signals emitted is very high, all created at a dazzling speed.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif;"><img height="176" hspace="5" src="http://www.harunyahya.com/books/science/biomimetics/images/image-(135).jpg" style="text-align: right;" width="259" /></div><div style="text-align: justify;">The eye’s mechanism is much more functional. One can clearly understand the astonishing perfection of its structure when one considers that it never needs to repair or replace any parts.</div><br />
<div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><a href="" name="92"></a>As medical science advances, the human eye’s miraculous nature is being ever better understood. By applying to technology the knowledge we’re acquiring about the eye, ever more advanced cameras and countless optical systems are being developed. But no matter how much technology advances, the electronic devices manufactured so far remain a primitive copy of the eye itself. No computer-supported camera or other man-made gadget can rival the human eye. <a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics07.php#dipnot" style="color: #7f0000; text-decoration: none;">92</a></div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">So how did this complex structure in the eye emerge? It is undoubtedly impossible for any structure this complex to form itself by trial and error, over a long period of time. The eye’s structure is such that it won’t be able to work if even one component is lacking. No design can come about by chance, and the eye reveals a very clear and incomparable design. This leads us to the question of Who designed it. The only Originator of the design is God. The fact that such an organ has been given to us, allowing us to perceive everything round us in the best possible way, is a great reason for us to thank Him. As we are told in one verse of the Qur’an,</div><blockquote style="font-family: Geneva, Arial, Helvetica, san-serif;"><div class="ayetler" style="color: black; font-family: Geneva, Arial, Helvetica, san-serif; font-style: normal; font-weight: bold; padding-bottom: 0px; padding-left: 0cm; padding-right: 0px; padding-top: 0px; text-align: justify;">Say: “It is He Who brought you into being and gave you hearing, sight and hearts. What little thanks you show!” (Qur’an, 67: 23)</div></blockquote><div class="baslik2bordo" style="color: #7f0000; font-family: 'Times New Roman', Times, serif; font-style: normal; font-weight: bold; text-decoration: none;"><img height="172" src="http://www.harunyahya.com/books/science/biomimetics/images/image-(106).jpg" style="text-align: right;" width="181" /></div><div class="baslik2bordo" style="color: #7f0000; font-family: 'Times New Roman', Times, serif; font-style: normal; font-weight: bold; text-decoration: none;"></div><div style="text-align: right;"><br />

<div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">Amazed at the eye’s functioning, and seeking to duplicate its superior features in the technological field, scientists have recently begun to examine more closely the flawless mechanisms of living things in nature. A number of studies in biomimetics have greatly accelerated progress in the technological arena.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />

</div><div style="text-align: justify;">The retinal cells in our eyes recognize and interpret light, then send this information to other cells to which they are connected. All these visual processes have inspired a new model for computers.</div><br />
<div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><a href="" name="93"></a>The retina, consisting of nerve cells tightly linked to one another, is not restricted to only perceiving light. Before signals from the retina are transmitted to the brain, they undergo a huge number of processes. For instance, cells that compose the retina process information to accentuate the edges of objects, called "edge extraction," boost the power of the electrical signal and carry out adjustments, depending on whether the ambient illumination is dark or bright. Yes, powerful modern computers are capable of carrying out similar functions, but the retina’s neural network uses a relatively much smaller amount of energy. <a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics07.php#dipnot" style="color: #7f0000; text-decoration: none;">93</a></div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />

</div></a><div style="text-align: justify;"><a href="" name="94">One research team, led by Carver Mead of the California Institute of Technology, is looking into the secrets that allow the retina to carry out all these processes so easily. Together with the Caltech biologist Misha Mahowald, Mead designed electronic circuits containing light receptors like those in the eye, with a structure similar to the retina’s neural network. Also as in the retina, these light receptors are connected to others, allowing the electronic circuit components to communicate with one another, just as retinal cells do. </a><a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics07.php#dipnot" style="color: #7f0000; text-decoration: none;">94</a></div><br />
<div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">Despite all these efforts, however, it’s proved to be impossible to imitate the retinal network’s circuitry, because of the vast number of individual cells in the living retina and the connections between them. Design engineers, therefore, are now trying to understand how the retina’s neural network operates and are designing simpler circuits which, ideally, can perform similar functions.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />

</div><div style="text-align: justify;">Researchers from Cornell University in Ithaca, N.Y., began studying hearing systems in nature in order to design more sensitive auditory equipment. As a result, they realized that the ear of <em>Ormia ochracea</em>, and its extraordinary design could lead to a revolution in hearing aids. The ear of this species of fly can identify a sound’s direction in a most accurate manner. As an article of U.S. National Institute on Deafness and Other Communication Disorders describes it:</div><br />
<div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><a href="" name="95"></a>Humans were considered the best creatures at locating sounds... Because humans have six or so inches between their right and left ears, the difference between what each ear hears is greater, making it easier to compute the location of the sound. But with its right ear only half a millimeter away from its left, Ormia has a much bigger challenge in telling the difference. <a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics07.php#dipnot" style="color: #7f0000; text-decoration: none;">95</a></div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">Identifying the direction of sounds is essential for <em>Ormia</em>’s survival, because it must locate crickets as a source of food for its larvae. The fly deposits its eggs atop the cricket, and its larvae feed on the insect after they emerge.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><em>Ormia</em> has very sensitive ears designed to establish the location of a chirping cricket. It can pinpoint sounds exceptionally well. </div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif;"><img height="238" src="http://www.harunyahya.com/books/science/biomimetics/images/image-(70).jpg" style="text-align: right;" width="150" /><em><img height="140" src="http://www.harunyahya.com/books/science/biomimetics/images/image-(212).jpg" style="text-align: left;" width="247" /></em><a href="" name="96"></a></div><a href="" name="96"><div style="text-align: justify;"><br />
</div></a><div style="text-align: justify;"><a href="" name="96">For locating sounds, the human brain uses a similar method to that of <em>Ormia</em>. For this purpose, it’s enough for sound to reach the closer ear first, then the more distant one. When a sound wave strikes the eardrum’s membrane, it is converted into an electrical signal and immediately transmitted to the brain. The brain calculates the milliseconds of difference between the sound’s reaching both ears and thus determines the direction it came from. The fly, whose brain is no larger than a pinhead, performs this calculation only in 50 nanoseconds, 1,000 times faster than we can.</a><a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics07.php#dipnot" style="color: #7f0000; text-decoration: none;"> 96</a></div><br />

As we have shown, even the tiny fly possesses a superior structure and design that demolishes evolution’s nonsensical theory of "coincidence." In the same way, this minute creature’s every organ and feature display the infinite might and knowledge of our Creator. It is impossible for such a tiny yet complex creature to be recreated even by skillful scientists working together and employing the most advanced technology, let alone through an imaginary "evolutionary" process.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">Even this tiny fly constitutes a self-evident proof of God’s superior creation.</div>(Adnan Oktar)http://www.blogger.com/profile/07941900256013358025noreply@blogger.com0tag:blogger.com,1999:blog-1620098504704477893.post-3412249442632580602010-06-11T11:59:00.000-07:002010-06-11T11:59:44.606-07:00BIOMIMETICS AND ARCHITECTURE<div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">Since the designs in nature are quite flawless, their inspirations are now frequently employed in architectural designs. All the features necessary in a structure, such as energy savings, beauty, functionality and durability have already been created in the natural world. No matter how many superior systems human beings may run across, their imitations can never be as good or practical as the originals.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">In order to copy nature’s designs and implement them in architectural design, a high level of engineering know-how is essential. Yet the living things in the natural world know nothing about load bearing or architectural principles. Nor do they have any opportunity of understanding them. All living things behave in the manner God inspires in them. In one verse, He reveals that all living things are under His control:</div><blockquote style="font-family: Geneva, Arial, Helvetica, san-serif; font-size: 12px;"><div class="ayetler" style="color: black; font-family: Geneva, Arial, Helvetica, san-serif; font-style: normal; font-weight: bold; padding-bottom: 0px; padding-left: 0cm; padding-right: 0px; padding-top: 0px; text-align: justify;"><span class="Apple-style-span" style="font-size: medium;">… There is no creature He does not hold by the forelock...

</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; font-size: 12px;">The Crystal Palace was designed by landscape designer Joseph Paxton, who drew inspiration from <em>Victoria</em><em> amazonica</em>, a species of water lily.

</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><a href="" name="98"></a>When Paxton examined these leaves’ undersides, he found they were supported by fibrous extensions like ribs. Each leaf has radial ribs stiffened by slender crossribs. Paxton thought these ribs could be duplicated as weight-bearing iron struts, and the leaves themselves as the glass panes. In this way, he succeeded in constructing a roof made of glass and iron, which was very light yet still very strong. <a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics08.php#dipnot" style="color: #7f0000; text-decoration: none;">98</a></div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">The water lily begins growing in the mud at the bottom of Amazonian lakes, but in order to survive, it needs to reach the surface. When it comes to the surface of the water it stops growing, then starts forming thorn-tipped buds. In as little as a few hours, these buds open into enormous leaves up to two meters across. The more area they cover on the surface of the river, the more sunlight they can obtain with which to carry out photosynthesis.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><a href="" name="99"></a>Another thing the root of the water lily requires is oxygen, of which there is little in the muddy bottom where the plant is rooted. However, tubes running down the long stems of the leaves, which can reach as much as 11 meters (35 feet)in height, serve as channels that carry oxygen from the leaves down to the roots. <a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics08.php#dipnot" style="color: #7f0000; text-decoration: none;">99</a></div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">As the seed starts to grow in the depths of the lake, how does it know that it will soon need light and oxygen, without which it can’t survive, and that everything it requires is at the surface of the water?

<div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">According to evolutionist logic, therefore, new water lilies should have drowned under several feet of water and become extinct long ago. Yet the fact is that these water lilies are still around today, in all their perfection.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">Amazon lilies, after reaching the light and oxygen they need, curl their leaves upwards at the edges so that they do not fill with water and sink. These precautions may help them survive, but if the species is to continue, they need some insects to carry their pollen to other lilies. In the Amazon, beetles have a special attraction to the color white and therefore, select this lily’s flowers to land on. With the arrival of this six-legged guests, who will allow the Amazon lilies to survive down the generations, the petals close up, preventing the insects from escaping, while offering them large quantities of pollen. After holding them imprisoned for the whole night and throughout the next day, the flower then releases them, also changing color so that the beetles do not bring its own pollen back to it. The lily, formerly a shining white, now adorns the river in a dark pink.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />

</div><div style="font-family: Geneva, Arial, Helvetica, san-serif;">Even today, the Eiffel Tower is accepted as a marvel of engineering, but the event that led to its design took place back to 40 years before its construction. This was a study in Zurich aimed at revealing "the anatomical structure of the thigh bone."</div><div style="font-family: Geneva, Arial, Helvetica, san-serif;">In the early 1850s, the anatomist Hermann von Meyer was studying the part of the thigh bone that inserts into the hip joint. The thigh bone head extends sideways into the hip socket, and bears the body's weight off-center. Von Meyer saw that the inside of the thigh bone, which is capable of withstanding a weight of one ton when in a vertical position, consists not of one single piece, but contains an orderly latticework of tiny ridges of bone known as trabeculae.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif;">In 1866, when the Swiss engineer Karl Cullman visited von Meyer’s laboratory, the anatomist von Meyer showed him a piece of bone he had been studying. Cullman realized that the bone’s structure was designed to reduce the effects of weight load and pressure. The trabeculae were effectively a series of studs and braces arranged along the lines of force generated when standing. As a mathematician and engineer, Cullman translated these findings into applicable theory and the model lead to the design of the Eiffel Tower.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif;"><a href="" name="100"></a>As in the thigh bone, the Eiffel Tower’s metal curves formed a lattice built from metal studs and braces. Thanks to this structure, the tower was easily able to stand up to the bending and shearing effects caused by the wind. <a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics08.php#dipnot" style="color: #7f0000; text-decoration: none;">100</a></div><div style="font-family: Geneva, Arial, Helvetica, san-serif; font-size: 12px;"><br />

Improvements in electronics and computer technology have let us construct robots that can work in such places. Eventually, this discipline split away from electronics and mechanics to form a branch of science in its own right—robotics. These days, those who work with robotics have a new concept on their agenda: biomimetic robotics.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><img height="200" src="http://www.harunyahya.com/books/science/biomimetics/images/image-(191).jpg" width="185" /><img height="200" src="http://www.harunyahya.com/books/science/biomimetics/images/image-(192).jpg" width="201" /><img height="200" src="http://www.harunyahya.com/books/science/biomimetics/images/image-(193).jpg" width="188" /></div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">Scientists and engineers engaged in robotics now believe that designing robots for a particular task isn't very practical. They consider it easier and makes better sense to build robots that imitate the features and abilities of living things, indigenous to the environments where these robots are to be employed. For desert exploration, for example, they’ll create a biomimetic robot resembling a scorpion or an ant. A book called <em>Neurotechnology for Biomimetic Robots </em>contains the following information on this subject:</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">Biomimetic robots differ from traditional robots in that they are agile, relatively cheap, and able to deal with real-world environments. The engineering of these robots requires a thorough understanding of the biological systems on which they are based, at both the biomechanical and physiological levels.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><a href="" name="103"></a>... The ultimate goal is to develop a truly autonomous robot, one able to navigate and interact with its environment solely on the basis of sensory feedback without prompting from a human operator. <a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics09.php#dipnot" style="color: #7f0000; text-decoration: none;">103</a></div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><a href="" name="104"></a>What led scientists to imitate living things was their flawless physical designs. Engineer Hans J. Schneebeli, designer of the robotic device known as the Karlsruhe Hand, stated that the more he worked on robotic hands, the more he admired the human hand. He added that they still need plenty of time to duplicate even a few of the many tasks that a human hand can accomplish. <a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics09.php#dipnot" style="color: #7f0000; text-decoration: none;">104</a></div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">On occasion, scientists from such different disciplines as computer technology, mechanics, electronics, mathematics, physics, chemistry and biology must join forces to replicate just one feature of a living creature. Yet evolutionist thinking still maintains that the extraordinarily complex structures of living things could have come about unplanned, of their own accord.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />

</div><div style="text-align: justify;">For those engaged in robotics, one of the problems they encounter most frequently is maintaining equilibrium. Even robots equipped with the very latest technology can lose their balance when walking. A three-year-old child can manage to regain balance with no difficulty, yet robots lacking this ability are, of necessity, stationary and of very little use. In fact, one robot that NASA prepared for duty on the planet Mars couldn’t be used at all, for that very reason. After that, robot experts abandoned attempts to build a balance-establishing mechanism and instead looked to a creature that never loses its balance—the snake.</div><br />
<div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><a href="" name="105"></a>Unlike other vertebrates, snakes lack a hard spine and limbs, and have been created in such a way as to enter cracks and crevices. They can expand and contract the diameter of their bodies, can cling to branches and glide over rocks. Snakes’ properties inspired for a new robotic, interplanetary probe developed by NASA's Ames Research Center which they called the "snakebot." This robot thus was designed to be in a constant state of balance, without ever getting caught up by obstacles. <a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics09.php#dipnot" style="color: #7f0000; text-decoration: none;">105</a></div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />

</div><div style="text-align: justify;">The inner ear performs a vital role in our system of balance, controlling our whole body at every moment and allows us to perform the delicate adjustments required by a tightrope walker, for example.</div><br />
<div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">This center of balance in the inner ear, known as the labyrinth, consists of three small semicircular canals. They are 6.5 mm (0.26 in) in diameter and, in cross-section, the hollow space inside them measures 0.4 mm (0.016 in). The three are laid out in orthogonal planes. An individual canal senses rotations in one of three orthogonal directions. Thus the three canals combine their results and give the ability to sense rotations in any direction in three-dimensional space.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">Inside each of these three canals is a viscous fluid. At one end of the tube is a gelatinous cap (cupula), which sits on a bulged area (crista)covered with sensory hair cells. When we turn our heads, walk, or make any movement, the fluid within these canals lags behind because of inertia. The fluid pushes against the cupula, deflecting it. This deflection is measured by the hair cells in the crista as the hairs’ vibration alters the ion balance in the cells connected to them, producing electrical signals.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif;"></div><div style="text-align: justify;"><img height="372" hspace="5" src="http://www.harunyahya.com/books/science/biomimetics/images/image-(146).jpg" style="text-align: left;" width="298" /></div><div style="text-align: justify;"><br />
</div><div style="text-align: justify;">These signals produced in the inner ear are transmitted by means of nerves to the cerebellum at the back of our brain. These transmitter nerves from the labyrinth to the cerebellum have been shown to contain 20,000 nerve fibers.</div><br />
<div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">The cerebellum interprets this information from the labyrinth, but in order to maintain balance, it also needs other information. Therefore, the cerebellum receives constant information from the eyes and from muscles throughout the body, rapidly analyzing all this information and calculating the body’s position relative to gravity. Then, based on these instant calculations, it notifies the muscles via the nerves of the exact movements they should make to maintain balance.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">These extraordinary processes occur in less than 1/100th of a second. We are able to walk, run, ride a bicycle, and play sports without even being aware all this is going on. Yet if were we to put down on paper all the calculations going on in our bodies at any one instant, the formulae would fill thousands of pages.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">Totally flawless, our balance system functions by means of several very complex mechanisms, all interconnected and working together. Modern science and technology have yet to unravel all the details of their operative principles, let alone imitate them.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">It is of course impossible for such a complex design to have come about by chance, as evolution theory would have us believe. Every design reveals the existence of a conscious designer. Our balance system’s superior design is one more proof of the existence of God, Who created that system so impeccably, and of His infinite wisdom.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">In the face of this realization, man’s responsibility is to give thanks to God, Who gave him such a structure.</div><table border="0" cellpadding="0" cellspacing="0" style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><tbody>

The reason the project selected a scorpion as its model is that the robot was to operate in the desert. Scorpions have been able to survive harsh desert conditions ever since their creation. But another reason why DARPA selected a scorpion was that along with being able to move over tough terrain very easily, its reflexes are much simpler than those of mammals—and can be imitated. </a><a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics09.php#dipnot" style="color: #7f0000; text-decoration: none;">106</a></div><br />

Upon encountering a difficulty, it merely relies on its reflexes. This allows it to overcome any obstacles that might impede its progress—a rock, for example. At the front, the robot has two ultrasonic sensors. Should it encounter an obstacle more than half its own height, it will try going around it. If the detector on the left identifies an obstacle, it will turn to the right.

</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">Even fully-equipped human divers have difficulty in moving through turbulent and murky waters, crawling along the bottom where it may be rough, sandy or covered with algae. Lobsters can, and very easily too. But so far, no robot made for use on the sea bed has been successful in such environments. </div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><a href="" name="110"></a>Joseph Ayers, Director of the Marine Science Center at Northeastern University in Boston is leading a project to develop a robot that imitates the lobster.

</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">They expect to use this “robo-lobster” in finding and disarming mines. Ayers says the robot will be ideally suited to this kind of work:</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><a href="" name="111"></a>. . . the sequence of behavioral acts that a lobster performs when it searches for food is exactly what one would want a robot to perform to find and neutralize underwater mines. <a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics09.php#dipnot" style="color: #7f0000; text-decoration: none;">111</a></div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">Lobsters’ shape helps them resist tumbling or moving in fast-moving water. They are able to proceed in the direction they want under the most difficult conditions, even over very rough terrain. In the same way, the robo-lobster will use its tail and claws for stability.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><a href="" name="112"></a>On the robot, micro-electro-mechanical sensors (MEMS) imitate the lobster’s sensory organs. Equipped with water current sensors and antennae, the robot can adapt its movements to the currents of the water around it. A live lobster uses hairs to determine the direction of currents, and the robot lobster’s electro-mechanical sensors are intended to do the same thing. <a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics09.php#dipnot" style="color: #7f0000; text-decoration: none;">112</a></div><div class="baslik2bordo" style="color: #7f0000; font-family: 'Times New Roman', Times, serif; font-style: normal; font-weight: bold; text-align: justify; text-decoration: none;"><br />

</div><div style="text-align: justify;">Underwater creatures such as crabs and lobsters use their sense of smell to find food, mates or to flee from predators. One study carried out by researchers from the Universities of California at Berkeley and Stanford revealed how lobsters smell the world around them.</div><br />
<div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">Lobsters possess a very sensitive sense of smell, whose features will open up new horizons for robot engineers trying to build new odor sensors. Mimi A. R. Koehl, a professor of integrative biology in the College of Letters & Science at University of California, Berkeley, says:</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><a href="" name="113"></a>If you want to build unmanned vehicles or robots to go into toxic sites where you do not want to send a scuba diver, and if you want those robots to locate something by smell, you need to design noses or olfactory antennae for them. <a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics09.php#dipnot" style="color: #7f0000; text-decoration: none;">113</a></div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">Lobsters and other crustaceans smell by flicking a pair of antennules toward the source of the odor, so that the chemosensory hairs on the ends of the antennules come into contact with the water-borne odor molecules. The spiny lobster <em>Panulirus argus</em>, which lives in the Caribbean Sea, has antennules 30 cm (3 to 4 inches) in length. On the outer edge of one of the split ends of its antennules are hairs resembling a brush—a region particularly sensitive to chemicals.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">A group of researchers led by Professor Koehl made a mechanical lobster that flicked its antennules in the same way. Tests and observations of this robot, dubbed Rasta Lobsta, were performed to study in detail the technique that lobsters employ in order to smell.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />

</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">When the lobster wants to smell something, during the downstroke, it pushes the antennule through the water fast enough for the water bearing the odor to penetrate into the brush of sensory hairs. On the return stroke, however, it sweeps more slowly, so the water is unable to move between the hairs and the odor plume that penetrated between the hairs during the downstroke are trapped until the next rapid downstroke.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><a href="" name="114"></a>The antennules move forward and back at the ideal speed for the lobster to be able to smell. Tests have shown that if the antennules moved more slowly, the water would not flow between the hairs, reducing the crustacean’s ability to smell. Therefore, it uses its antennules in such a manner that it’s able to preserve and capture even small differences in odor concentration in a plume. <a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics09.php#dipnot" style="color: #7f0000; text-decoration: none;">114</a></div><div class="baslik2bordo" style="color: #7f0000; font-family: 'Times New Roman', Times, serif; font-style: normal; font-weight: bold; text-align: justify; text-decoration: none;"><br />

</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">The skin covering a worm’s cylindrical body consists of fibers that are wound in a crossed helical form around and along the body—a most impressive design. The contraction of muscles in the body wall leads to an increase in the internal pressure, and the worm is able to change shape as the fibers in the skin allow it to go from short and fat to long and thin. This is the basis of how worms move.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />

</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">This matchless mechanical system is presently inspiring new projects at Reading University’s Centre for Biomimetics. In one experiment, cylinders of various fiber angles were arranged along the lines of the worm’s anatomy. The plan is to fill these cylinders with a water-absorbent polymer gel. Water causes this gel to expand. In this way, chemical energy is converted to mechanical energy in just the right place, and the resulting pressure will be contained safely inside the helically-wound bag. Once the swelling and contracting of the polymer gel is controlled, it is hoped that the resulting system will operate like an artificial muscle. <a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics09.php#dipnot" style="color: #7f0000; text-decoration: none;">115</a></div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">Every living thing that man takes as a model, and every system in it, is a sign of God for those who believe.

The worm, octopus, starfish and anemone are some of the best examples; yet shape-changing is found much less frequently in technological equipment. In those few examples that do exist, hydraulic pressure is employed. In lifts, for example, hydraulic liquid is pumped into a thin cylinder to raise heavy objects. To lower the lift, the cylinder is emptied again. Starfish also use hydraulic pressure to move. Along the undersides of its arms, the echinoderm possesses tube-like feet, attached to an internal, fluid-filled tubing system. When its muscles contract the tubes, the resulting hydraulic pressure sends fluid to the feet. Using its muscles, the starfish uses hydraulic power to set up a wave motion in its feet, moving forward and back and allowing the starfish to progress in one direction.</div></td></tr>

Until recently, we didn’t understand how it could be possible for any vertebrate animal to climb up walls like the cartoon and film hero Spiderman. Now, years of research have finally uncovered the secret on which their extraordinary ability depends. Little steps by the gecko have led to enormous discoveries with tremendous implications, particularly for robot designers. A few can be summarized as follows:</div><br />
<div style="font-family: Geneva, Arial, Helvetica, san-serif;"></div><div style="text-align: justify;">- Researchers in California believe that the lizard’s “sticky” toes can help in developing a dry, and self-cleaning adhesive. <a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics09.php#dipnot" style="color: #7f0000; text-decoration: none;">116</a></div><div style="text-align: justify;"><br />

In order to produce technology in any given area, first of all we need to possess information. Next, the scientists and technical personnel who are to use this information must be added to the equation. These personnel need the right materials and the facilities in which to make use of them. For all these reasons, producing technology is a difficult business. Indeed, the history of those advances we describe as “technological” is by no means a long one. Even today, though many countries enjoy technology, very few of them actually produce it.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">As scientific circles have noted, most of the technological products emerging as the result of investment, information and research have their “originals” and counterparts in nature.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">Phil Gates, a well-known scientist and author of the book <em>Wild Technology</em>, expresses this in the following terms:</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><a href="" name="123"></a>Many of our best inventions are copied from, or already in use by, other living things. We have only discovered a tiny fraction of the vast numbers of living organisms that share our planet. Somewhere, amongst the millions of organisms that remain undiscovered, there are natural inventions that could improve our lives. They could provide new medicines, building materials, ways of controlling pests and dealing with pollution. <a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics10.php#dipnot" style="color: #7f0000; text-decoration: none;">123</a></div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">Every niche of our surroundings—from the sky to the land to the depths of the oceans—are full of countless “technological” marvels, each of them a product of creation. Even the simplest industrial product has a designer and place where it was manufactured. That being so, it would be obviously irrational to claim that living things, possessing systems incomparably superior to huge factories with their state-of-the-art machinery, could have arisen through chance, by themselves, as a result of natural conditions.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">Every living thing possesses a superior, perfect design that emerged flawless and complete from the very day of its creation, because God is He Who creates flawlessly.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">In this chapter we’ll examine some marvels of creation and compare them to present-day technology.

</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">Our bodies generate heat energy by digesting the food we’ve eaten during the day. The best way to prevent the loss of this warmth is to keep it from leaving our bodies too soon. That is why we wear varying layers of clothing, depending on the weather. Warm air, trapped between the layers, is unable to reach outside. Preventing energy loss in this way is known as insulation.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><a href="" name="125"></a>The eider duck employs the exact same method. Like many birds, its feathers enable it to fly and also keep it warm. It uses its soft and fluffy chest feathers in building its nest. This down protects the eggs and the emerging featherless chicks from the cold air. Since the eider’s feathers retain warm air, they exemplify the very best form of natural insulation. <a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics10.php#dipnot" style="color: #7f0000; text-decoration: none;">125</a></div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">Modern mountain climbers keep their bodies warm by wearing special costumes filled with feathers with high heat-retaining properties, similar to those of eider feathers.</div><div align="justify" style="font-family: Geneva, Arial, Helvetica, san-serif;"><br />

Yet there is no question of them ever freezing. All of them possess circulatory systems that reduce heat loss to a minimum. In these birds, heated and chilled blood circulate in different blood vessels, but these vessels run close together, however. In this way, warm blood flowing to the extremities downwards warms the cold blood circulating upwards. This also reduces the shock of cold blood returning to the body from the feet. This natural heat exchange mechanism, known as counter-current, is the same as that used in various machines. <a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics10.php#dipnot" style="color: #7f0000; text-decoration: none;">128</a></div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />

These hairs act like electrical switches. The instant one is touched, it gives off electrical signals that change the water balance in the plant’s cells, and trigger the flow of water out of cells along the leaf midrib, closing the trap. <a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics10.php#dipnot" style="color: #7f0000; text-decoration: none;">129</a></div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />

</div></a><div style="text-align: justify;"><a href="" name="130">The switches controlling the flow of current in electrical circuits operate in much the same way. When the switch is turned off, electric current cannot flow. As soon as it is turned on and the circuit is completed, however, electric current begins to flow along the wire once again. Similarly, animals and plants use a great many biological switches to initiate or halt the flow of electrical signals to the relevant parts of their bodies. </a><a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics10.php#dipnot" style="color: #7f0000; text-decoration: none;">130</a></div><br />

</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><a href="" name="131"></a>The Venus flytrap’s circuit actually works like two electrical switches connected together in series. Two hairs must be stimulated before the trap to close. <a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics10.php#dipnot" style="color: #7f0000; text-decoration: none;">131</a> This precaution prevents unnecessary closing triggered by such phenomena as raindrops.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">Of course, the Venus flytrap knows nothing about electric current or the switches that let these currents flow. Nor is it possible for the plant to receive any kind of training in these areas. That being so, how does it come by this knowledge, which even a human being can’t learn without special instruction, and how is it able to employ it so flawlessly? God, the Ruler of all, teaches the plants what to do. The Venus flytrap acts under His inspiration.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />

</div><div style="font-family: Geneva, Arial, Helvetica, san-serif;">Many animals build underground shelters that require special features to defend them from predators.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif;">In such shelters, the tunnels need to be at a specific distance from the surface and parallel to the ground, or else they may easily be flooded. If the tunnels are dug at a sharp angle, that poses a risk of collapse. Another problem in tunnel construction is meeting the need for air and ventilation.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif;"><img align="left" height="170" hspace="5" src="http://www.harunyahya.com/books/science/biomimetics/images/image-(113).jpg" width="227" /></div><div style="text-align: justify;">Prairie dogs are social animals, living in large groups in burrows they construct underground. As their population grows, they dig new burrows, joining them up with tunnels. The space that such complexes occupy can sometimes equal the size of a small city, and thus ventilation assumes a vital importance. Therefore prairie dogs build aboveground towers where their tunnels emerge, rather like volcanoes, which let air be drawn into the city below.</div><br />
<div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><a href="" name="133"></a>Air travels from regions of high pressure to areas of low. Some of the towers that prairie dogs build are taller than others. Their differences in height give rise to different levels of air pressure in the tunnel entrances. This way, air enters towers with low air pressure above them and emerges through ones with high pressure. Air drawn into the tunnels passes through all the nests, thus establishing an ideal air circulation system. <a href="http://www.harunyahya.com/books/science/biomimetics/biomimetics10.php#dipnot" style="color: #7f0000; text-decoration: none;">133</a></div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />

</div><div style="text-align: justify;">To construct a ventilation system such as employed in prairie dogs' tunnels, knowledge of tunnel building, of high and low air pressure, and how they change with altitude are all essential. All these considerations require consciousness, and all these activities indicate the presence of reason and judgment. Therefore, we need to examine the source of this intelligence in the prairie dogs, since clearly it does not belong to the animals themselves—and, contrary to what evolutionists claim, cannot have resulted from blind chance.</div><br />

</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">Scientists are continually amazed at the incomparable structures and systems they discover in nature—and they express their wonder by copying them to create new technologies for mankind’s benefit. They’ve realized that those impeccable systems and extraordinary techniques that nature employs, far superior to their own knowledge and capabilities, offer incomparable solutions to existing problems. Accordingly, they’re now resorting to natural designs in a great many areas where, after years of effort, they’ve been unable to come up with solutions. As a result, they’ve been able to produce successful results within very short spaces of time. Furthermore, by imitating nature, scientists have saved considerable terms of time and effort, and applied material resources far more effectively. </div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;"><br />
</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">Recognizing the superior nature of natural designs, evolutionists are suffering yet another disappointment, another loss of hope. Once again, their unscientific claims that living things develop gradually, from the simple to the complex, and that the designs of living things came about through chance has been demonstrated to be untrue. Also, they’ve had to accept, albeit unwillingly, that the incomparable art that has so astonished them—that the knowledge and reason they so greatly admire—cannot be the work of chance, but only of our Almighty Creator.</div><div style="font-family: Geneva, Arial, Helvetica, san-serif; text-align: justify;">It is God, the Lord of the worlds, Who creates the flawless and unmatched systems in all living things; He Who creates everything flawlessly. Those who refuse to accept this fact will suffer an irreparable sorrow on the Day of Judgment. In the Qur’an, God describes how such people waste their time in this world. The Qur’an describes in these terms the impeccable nature of our Lord’s artistry:</div><blockquote style="font-family: Geneva, Arial, Helvetica, san-serif;"><div class="ayetler" style="color: black; font-family: Geneva, Arial, Helvetica, san-serif; font-style: normal; font-weight: bold; padding-bottom: 0px; padding-left: 0cm; padding-right: 0px; padding-top: 0px; text-align: justify;">He, Who created the seven heavens in layers.

The giant excavators humans use to dig tunnels perform a similar function to the radula. However, the tips of these machines’ drills wear out and have to be frequently replaced.</span></td></tr>
