![]() The spider is a magnificent engineer
Spiders are a specific class of animals called arachnids that range in size from the small jumping spiders commonly seen …. Spiders are a specific class of animals called arachnids that range in size from the small jumping spiders commonly seen in residential areas to the Goliath Bird eater tarantula of South America (the largest spider in the world). They differ from insects because they have two body parts and eight legs. Formal categorizations of spiders often start by placing them in families, based on specific criteria. ![]() A less formal way to think about different types of spiders starts by considering their eating habits. Spiders are carnivores that catch their food in one of two ways. They either use a web or actively hunt on the land or water. ![]() A photo of a giant spider eating a finch ![]() A photograph of a giant spider eating a bird in an Australian garden Size of spiders Spiders occur in a large range of sizes. The smallest Patu digua are less than 0.37 mm in body length. The largest and heaviest spiders occur among tarantulas, which can have body lengths up to 90 mm (about 3.5 inches) and leg spans up to 250 mm (about 10 inches). Spider Feet many spiders have special adaptations that allow them to walk easily along relatively smooth or vertical surfaces. ![]() Spiders have thick brushes of hair, each ending in tiny microscopic feet that let it walk up vertical surfaces. The end of each leg is covered with thick brushes of hair, and the end of each hair is covered in tiny microscopic "feet." All the tiny feet grip the small bumps on whatever the spider is walking on, allowing the spider to move easily over most terrain. Spider Vision while most spiders have multiple pairs of eyes, vision is a secondary sense in the vast majority of species. Most spiders primarily interact with the world through tactile sensation. ![]() Electron microscope image of one of a spider's sensitive hairs They are covered in highly sensitive hairs that pick up even low-level vibrations in whatever the spider is standing on (the ground, floor, leaf or web, for example). Many spiders have additional hairs which pick up vibrations in the air (sound). Most spiders also have a sense of taste and smell, which play a role in feeding and reproduction. Spider Brain one of the most amazing things about spiders is how much they can accomplish with such a small brain. The spider's central nervous system is made up of two relatively simple ganglia, or nerve cell clusters, connected to nerves leading to the spider's various muscles and sensory systems. ![]() Who programmed the brain of this little animal with such sophisticated programs? The simple instructions encoded in these nerve cells give spiders all the information they need to undertake complex tasks, such as building webs and attacking prey. Some species even exhibit learning behavior. If something isn't working -- a web in a particular spot, for example -- the spider will give up the activity and try something new. Hence, scientists say that spiders have programs in brain to enable them to design their webs and these program couldn't be developed or created by itself as claiming that nature or coincidence are the creator of these programs is equal to a man says that nature or coincidence had developed windows 7 or Xp. Indeed it isn't a rational way of thinking!!!!! Allah almighty is the creator who taught and programmed all of His creatures who says in Qur'an: (That is God, your Lord! there is no god but He, the Creator of all things: then worship ye Him: and He hath power to dispose of all affairs.* No vision can grasp Him, but His grasp is over all vision: He is above all comprehension yet is acquainted with all things.) (Sûrat Al-Anaam- verse102-103). -------------------- By: Abduldaem Al-Kaheel References: |

![]() Journey of the blood ![]() The human heart beats about 100,000 times a day. At this rate it still takes it thirty years to beat one billion times…. Blood begins its journey in the arteries as pure oxygenated blood and flows to different parts of the body. It returns to the veins that carry impure blood from different parts of the body. The impure venous blood flows from the right side of the heart to the lungs for purification. Who did manufacture that perfect design, coincidence or blind nature!!!? In the lungs, when we inhale oxygen, the latter comes in contact with the impure blood and a sort of combustion takes place with the blood being purified. The blood gives out carbonic acid generated from the poisonous matter and takes in oxygen. The purified blood is taken by the four pulmonary veins to the left ventricle. The blood is later pumped from the left ventricle into the aorta, from the aorta; it passes to the different arteries of the body. The pure blood from the arteries goes to the capillaries. From the capillaries, it goes to the tissues. The tissues take in the oxygen and give out carbon dioxide. The veins carry the impurities to the right side of the heart. To see a video We have to ask some primitive questions to atheists and disbelievers and they have to answer it by little common sense:
Any reasonable man should reach one result that there is only one great creator who created all of that. Allah says: ((such is) the artistry of God, who disposes of all things in perfect order: for he is well acquainted with all that ye do.) (Sûrat Al-Naml-verse88). -------------------- By: Abduldaem Al-Kaheel References: |

![]() The flying seeds
Allah says: (such is the artistry of God, who disposes of all things in perfect order: for he is well acquainted with all that ye do.)(Sûrat al Namel- verse88) let us look attentively at the precise creation of the great creator…. Researches demonstrate that animals are not the only organisms capable of flight. Many plants have winged seeds that glide or spiral to the ground. They can even catch an updraft and soar for long distances. ![]() The above image reveals a maple seed pods remain airborne for miles by harnessing the power of tornado-like vortexes generated as they spin. The flat, elongated pods are densest at their seed-containing ends, a configuration that causes them to rotate while falling. Rotation produces the pods’ nickname — whirlybirds — and creates tiny vortexes above their leading edges. By pulling in air, a vortex lowers air pressure above a pod’s surface, effectively sucking it upwards. According to the researchers, the pods are fully twice as aerodynamic while falling, and more efficient than standard aircraft wings and helicopter blades. Such vortexes are also found in hovering insects and bats, and may represent “a convergent aerodynamic solution in both animals and plants. Scientists believe that this solution could eventually inform the design of micro-helicopters and parachutes attached to planet-exploring robotic probes, raising the rather delicious possibility of humanity spreading through space. ![]() Image for red maple seeds, these seeds inspired human to an invention which can be utilized in a military use. Human imitates seeds Can anyone imagine that? Human imitates seeds… how come? A University of Maryland engineering student is using Mother Nature to develop an invention that could be helpful to national defense and that by using a maple seed to develop an invention is part of a larger school of thought at the engineering school. To see a video about the invention click here. Sending a small remote-controlled craft to a biological emergency is one possible application, also it could be dropped on an enemy nation with its camera flashing, yet look like a bird. It can navigate caves or map territory. Researchers believe that they can learn from the perfect designs of nature. But does it make any sense for any rational man to believe that vague and blind nature can design that perfect techniques? Allah says: (Say: "Who is the Lord and Sustainer of the heavens and the earth?" Say: "(It is) God." Say: "Do ye then take (for worship) protectors other than Him, such as have no power either for good or for harm to themselves?" Say: "Are the blind equal with those who see? Or the depths of darkness equal with light?" Or do they assign to God partners who have created (anything) as He has created, so that the creation seemed to them similar? Say: "God is the Creator of all things: He is the One, the Supreme and Irresistible.")(Sûrat al-Rad-verse16). Allah the creator of everything taught the seeds how to fly, also He almighty had exploited these seeds to learn human some useful techniques. Allah says: (And He has subjected to you, as from Him, all that is in the heavens and on earth: Behold, in that are Signs indeed for those who reflect) (Sûrat algathya-verse 13). -------------------- By: Abduldaem Al-Kaheel References: 2. http://wcbstv.com/watercooler/flight.of.maple.2.1260226 |

![]() This is the creation of Allah: The Green Snake Everything in universe testifies on the oneness of Allah the only creator. The green snake is a wonderful creature, let us see and glorify Allah …. The green snake is not likely to be confused with any other snake. It is 12-22 inches in length and non venomous. It has no outstanding markings, but it is a bright, brilliant green. The belly is usually bright yellow, but sometimes may be cream instead. The labials are the color of the belly. Some specimens may be buff or tan above instead of green. Habitat of the green snake The smooth green snake is found in a variety of habitats such as grassy, moist meadows, native prairies, and clearings in coniferous pine forests. This snake is seen crossing bike or hiking trails, or brought home by cats or dogs that hunt in large open fields, particularly near railroad tracks. A photo of a Green Snake on a Branch, can the nature or coincidence creates something like that? This snake is largely diurnal and less secretive than our other small snakes. It spends most of its day forging through tall grass or small shrubs, and though it is an accomplished climber, it is mostly terrestrial. It does not spend as much time under cover as other snakes, but do not underestimate the effectiveness of searching under boards, flat rocks, or other objects for these snakes. When approached in the field, these snakes take off for a short distance then freeze or gently sway with the grass, perfectly camouflaged. Most are discovered only when they venture onto the road. When they are picked up, they may thrash for a bit, but they rarely bite. Who taught those creatures to do such things? Indeed Allah almighty is the doer who is the creator of all creatures and everything. ![]() A new discovered type of green snakes which is 130 Cm of length and it depends on heat as a working mechanism. Allah almighty had supported this species by heat detection system to receive heat waves in day or night to enable it to eat the prey. Food of the green snake Green snakes are one of the few species of snakes that is entirely insectivorous. They like crickets, grasshoppers, and smooth caterpillars. This is probably one of the reasons this snake has declined in abundance. Hence, after all of the above we have to think rationally without any outer pressures and ask a question, who told these creatures how to feed itself by the suitable technique to its abilities and not to die by hunger? Indeed He is Allah almighty who imposed on Himself to give the needed provision for all creatures, He says: (And no moving (living) creature is there on earth but its provision is due from Allah. And He knows its dwelling place and its deposit (in the uterus, grave). All is in a Clear Book (Al-Lauh Al-Mahfûz - the Book of Decrees with Allah).)

![]() The Hummingbird
This is the fastest bird in nature according to size. It is advanced more than rockets and spacecraft, let us read and see… What is the Hummingbird? It's a bird, a thumb-size dervish with hyper kinetic wings that can beat 80 times a second, producing the faintest hum. Tail feathers paddle, steering gently in three dimensions. As the bird stares into the trumpet of a bright orange flower, a thread-thin tongue flickers from its needle beak. A sunbeam glances off its iridescent feathers, the reflected color as dazzling as a gemstone hung in a sunny ******** Little wonder hummingbirds inspire heartfelt affection and stuttering efforts at description. Even reserved scientists can't resist such words as "beautiful," "stunning," and "exotic." We can't go through these words without we stop and remind people with the following verse as Allah almighty says: (This is the creation of Allah. So show me that which those (whom you worship) besides Him have created. Nay, the Zâlimûn (polytheists, wrongdoers and those who do not believe in the Oneness of Allah) are in plain error.)(Sûrat Luqmân-verse 11). ![]() A greater wonder is that the seemingly fragile hummingbird is one of the toughest beasts in the animal kingdom. Some 330 species thrive in diverse and often brutal environments: from Alaska to Argentina; from the Arizona desert to the coast of Nova Scotia; from the lowland forests of Brazil to the 15,000-foot-plus (4,600 meters) snow line of the Andes. Karl Schuchmann, an ornithologist at Germany's Alexander Koenig Zoological Institute knows of a captive hummer that lived 17 years. "Imagine the durability of an organism of only five or six grams to live that long," he says. Its cranberry-size heart, which averages 500 beats a minute (while perching!), would have thumped four and a half billion times, nearly twice the total for a 70-year-old person. Glory to Allah!!!!!! Yet these little birds are durable only in life. In death their delicate, hollow bones almost never fossilize. Scientists say that the Hummingbird flies in an acrobatic style matched by few other birds. They hover often, and also fly upside down and backwards. These hummingbirds have extremely short legs, so they cannot walk or even hop with any efficiency. Hummingbirds hover to feed on flowers, nectar, and sap. During this floral feeding process, the birds pollinate many plants. These tiny birds are omnivores, sometimes feeding on insects and spiders. An adult ruby-throated hummingbird may eat twice its body weight in food each day, which it burns up with the high ****bolism necessary to sustain its rapid wing beat and energetic movements. The Anna's Hummingbird is now the fastest bird in the world. During courtship displays animals can attain amazing athletic performances," says Christopher James Clark, of the Museum of Vertebrate Zoology at the University of California, Berkley. "I used high-speed video to show that during a courtship dive, the Anna's Hummingbird reaches speeds of nearly 400 body lengths per second, twice the top speed of diving peregrine falcons or fighter jets," he writes in a summary of a research paper published today in the science journal Proceedings of the Royal Society B. To see the video click here . A male Anna's hummingbird caught during a display dive, compiled from high speed video. At the bottom of the dive, the bird flares its tail for 60 milliseconds. The inner vanes of the bird's two outer tail feathers vibrate in the 50 mph airstream to produce a brief chirp. "The accelerations experienced by the bird while pulling out of the dive almost reach 10g, also a performance record." This acceleration is remarkable, for instance trained Jet fighter pilots pass out under similar accelerations." He says. It means that this bird can afford what the trained Jet fighter pilots can't. Finally we have to ask ourselves a simple question, is the nature or what is called coincidence able to create and design that perfect and precise mechanism and abilities? Also, who hold these birds in the sky to keep them up not to fall down? And who supported those birds by these wonderful techniques? He is Allah be blessed and exalted who says: (That is God, your Lord! there is no god but He, the Creator of all things: then worship ye Him: and He hath power to dispose of all affairs.) (Sûrat Al-An’âm-verse102) also He says: (Do they not see the birds held (flying) in the midst of the sky? None holds them but Allah [none gave them the ability to fly but Allah]. Verily, in this are clear Ayât (proofs and signs) for people who believe (in the Oneness of Allah).)(Sûrat An-Nahl-verse79). -------------------- By: Abduldaem Al-Kaheel References: |

![]() This is the creation of Allah: The spiral galaxy NGC 1365 ![]() Let us look attentively at this great galaxy which contains hundreds of billions of stars, all of them are floating in a tremendous movement by the power of Allah Almighty… What is the spiral galaxy NGC 1365? The spiral galaxy NGC 1365 is a galaxy which is 60 million light years from Earth and its diameter is 200000 light years; it is truly a majestic island universe. NGC 1365 is a dominant member of the well-studied Fornax galaxy cluster. ![]() This impressively sharp color image shows intense star forming regions at the ends of the bar and along the spiral arms, as well as details of dust lanes cutting across the galaxy's bright core. At the core lies a super massive black hole. Astronomers think NGC 1365's prominent bar plays a crucial role in the galaxy's evolution, drawing gas and dust into a star-forming maelstrom and ultimately feeding material into the central black hole. The spiral galaxy NGC 1365 revolves a complete turn every 350 million years!!! Imagine how huge this galaxy is. Who found it, is it coincidence? Who put it in the right place in universe so that it doesn't collide with other galaxies? Who did create its stars, smoke and dust? Indeed He is Allah almighty who says: (This is the creation of Allah. So show me that which those (whom you worship) besides Him have created. Nay, the Zâlimûn (polytheists, wrongdoers and those who do not believe in the Oneness of Allah) are in plain error.)(Sûrat Luqmân-verse 11). -------------------- By: Abduldaem Al-Kaheel References: 1. http://apod.nasa.gov/apod/ap990624.html 2. http://science.nasa.gov/headlines/y2007/12apr_blackholeeclipse.htm |

Scientists say that nature gave that insect these unique abilities but we believe that Allah almighty is the only one who gave that insect its abilities and these unique techniques, God says: (Our Lord is He Who gave to each thing its form and nature, then guided it aright.)

![]() Mosquito's head
![]() This is a great photo for a mosquito, so that Allah almighty set a parable in the Qur'an by that insect. Let us read …. Engineers have set their sights on insect's eyes. They study how all these eyes work. It's giving them ideas for new inventions. Understanding how eyes capture light may lead to designs for cameras that take pictures inside the human body or to better ways to help planes land safely. So that scientists say insect Eyes Provide High-Tech Optical Inspiration. Here we have to know that their eyes are known as "the compound eyes" as it may utilize up to 29,000 lenses per eye. These individual lens systems or "ommatidia" function separately from each other. Each captures its own tiny piece of the overall picture. All these tiny images are processed simultaneously in the eye, which enables insects to have outstanding fast-motion detection. Scientists explain that compound eyes afford a panoramic view, allowing insects to see in many directions at once. Someday, scientists might even be able to make an artificial eye that works just like the real thing. We used to believe that insects are naïve creatures, but modern science shows us that these creatures are designed precisely with no mistake to perform its functions accurately. God be He blessed and exalted says about these small creatures: (Verily, Allah is not ashamed to set forth a parable even of a mosquito or so much more when it is bigger (or less when it is smaller) than it. And as for those who believe, they know that it is the Truth from their Lord, but as for those who disbelieve, they say: "What did Allah intend by this parable?" By it He misleads many, and many He guides thereby. And He misleads thereby only those who are Al-Fâsiqûn (the rebellious, disobedient to Allah).)(Sûrat Al-Baqarah- verse 26). But, what does Allah almighty mean by saying (or so much more when it is bigger)? Some people believe that Allah almighty means that there are small bugs live on the head of the mosquito, but it is wrong as there are millions of bacteria live on the body of all insects. We believe Allah means that He created these small insects and also all other bigger and smaller creatures than the insect, therefore we don't have to mock from these small creatures which Allah almighty said about it: (The Work of Allah, Who perfected all things, verily He is Well-Acquainted with what you do.)(Sûrat An-Naml-verse88). -------------------- By: Abduldaem Al-Kaheel References: National geographic website |

![]() Jumping techniques of cats
Cats can jump, once visually evaluated the distance, up to five or six times its own height …. Cats can jump, once visually evaluated the distance, up to five or six times its own height and it is not rare to see them climb for the simple self enjoyment of doing it. Thus they can adopt their favorite posture to observe from above what is happening below. The behavior that impulses cats to climb is very much tied to their survival natural instinct. There aren't many enemies that dominate the climbing technique cats do. Also, from their high shelters they can keep guard of the movements of their potential adversaries. The flexibility of their spine is another powerful weapon with which they count when they feel chosen or in danger, because it permits them to sneak through narrow openings or to escape through almost inaccessible places. Climbing down afterwards is another thing, because it is always harder and less elegant than when climbing up. Who taught that cat this wonderful jumping technique, is it nature or coincidence!!! Scientists say that the cat frequently has to climb down backwards and by stages until they are sufficiently close to the ground, then they turn and give a final jump forward . But scientists are asking, from the first day of birth the cat's brain is programmed by all needed programs to jump which is against claims of atheists that animals got their abilities by development. How can this cat learn different jumping techniques in the inside of her mother's womb? God be He blessed and exalted says: (He has created the heavens without any pillars that you see, and has set on the earth firm mountains lest it should shake with you. And He has scattered therein moving (living) creatures of all kinds. And we send down water (rain) from the sky, and we cause (plants) of every goodly kind to grow therein.* this is the creation of Allah. So show me that which those (whom you worship) besides Him have created. Nay, the Zâlimûn (polytheists, wrongdoers and those who do not believe in the Oneness of Allah) are in plain error.)

![]() The Carnivorous Plant
![]() Even plants, it can eat and shed blood of its victim, it's a great sign for the greatness of the creator be He exalted and blessed… The Carnivorous Plant is perfectly designed to perform the killing task, Glory to Allah!!!!! It is really a strange plant that eats insects, frogs, small birds and even mice but what is the mechanism? The trapping mechanism Just beneath the rim, on the inside, are glands that produce the nectar that attracts victim. Beneath the glands, there is a zone where the inner wall of the pitcher is smooth and covered in wax. The wax is comprised of small, loosely attached crystals. Insects are normally very good at being able to maintain their grip even on very smooth surfaces, but when they walk on the pitcher's wax, the wax crystals slough off and fall - with the prey - into the fluid below. The same waxy area prevents them being able to climb out again. Scientists say that pitcher plants are far more cunning than at first it seems. Observations in the wild showed that the rim of the pitcher was important. When it was dry, insects could walk on it perfectly well - but when it was wet after rain they slid off it into the trap. The researches knew this was unusual - most plant surfaces repel water, whereas the pitcher rims seemed unusually wet. They concluded it must have an interesting structure. Can the blind nature design such wonderful structure? Also scientists had found that when a dry rim had water dropped onto it, it rapidly spread out over the surface. Investigations showed that this spreading was enhanced by the outer tissue being covered in microscopically small ridges. The thin film of water prevented insects getting a grip and they slid off into the trap. The number of insects caught when the rim was wet was three times the number caught when it was dry; suggesting this and not the waxy layer below is actually the main trapping mechanism. There was plenty more to discover. Further observations showed that the rim became wet at times even when it had not been raining. Constant monitoring revealed a daily cycle - they were dry for much of the day and caught little, but became wet from early evening to morning and caught a lot more. It was found that the nectar the pitchers produced was hygroscopic - this means it can absorb moisture from the air. Thus thinned, it then spreads out over the rim. This is a new function for nectar not observed yet in other plants. It is possible that the plants can adjust how wet their lips become by adjusting the amount of nectar they produce. Another newly discovered fact concerns the fluid inside the pitcher. It is not just water. If a fly is dropped into water it can usually rapidly escape and fly away. But insects seem unable to escape from pitcher fluid. Observations and analysis showed this had nothing to do with surface tension or with any rapid kind of chemical attack. They also showed that only moving insects became wetted and drowned. Analysis showed that the fluid is what is called "viscoelastic". Movement within the fluid causes it to become stretchy and stringy. An insect's panicky movements cause the fluid to thicken so it is hard to swim. If it tries to lift a leg out of the fluid, it forms an elastic strand that is hard to break and pulls the leg back into the fluid. The faster the insect moves, the greater this effect. The only way it could escape would be to move more slowly, but they usually panic and thrash about. So, pitchers are far from a passive trap - they have sophisticated mechanisms for both catching prey and keeping them trapped once caught. Hence, we can conclude that this kind of plants has a brain also it possess observations machines and all needed liquids to perform its job. Who is the creator? Coincidence or nature!!!!!!!!!! Allah almighty says: (This is the creation of Allah. So show me that which those (whom you worship) besides Him have created. Nay, the Zâlimûn (polytheists, wrongdoers and those who do not believe in the Oneness of Allah) are in plain error.)(Sûrat Luqmân-verse11).
