Examples of Signs Leading to Faith

A 150-Ton Military Plane Imitates a 2-Gram Moth

Each AWACS plane is designed to establish the moment and direction of an attack before it is launched. These planes, designed by hundreds of scientists and engineers in facilities costing hundreds of millions of dollars, use giant radar and complex computer systems to monitor the activities of enemies located far away. One living thing in nature displays a comparable ability: the moth, which weighs no more than 2-2.5 grams.

Some species of moth are equipped with "early warning" systems, just like those in AWACS planes. Thanks to the ears underneath their wings, they can hear sound waves emitted by bats (their enemies) from as far away as 100 meters (330 feet). This allows them to identify their enemies' coordinates and decide whether an attack aimed at them has been initiated or not.

On the one hand we have an AWACS plane, weighing 150 tons and having a wingspan of 40 meters and a height of 44 meters, and, on the other hand, a moth weighing only a few grams, with a wingspan of 2.5 centimeters and a height of 2 centimeters. Both possess the same technological features. Furthermore, an AWACS plane requires 9.5 tons of fuel, while the moth can make do with a few milligrams of nectar. Kilometers of cable are used for its radar and computer systems, while just two short fibers are enough for a moth's perfect perception system.

These early warning systems, which are the accumulation of centuries of scientific experience and can only be fitted into planes weighing many tons, take place in an area no larger than the head of a match under the wings of a moth weighing only a few grams. Such a miraculous system, which people find very difficult to imitate even by pooling all their resources, has been flawlessly created in a tiny moth. God, the Creator of all, is the Lord and Ruler of the entire universe.


A Fly's Ear and Hearing Aids

One species of fly, known as Ormia ochracea, lays its larvae on crickets, in which the larvae develop and kill. It is not easy to find a cricket in a forested area. This particular fly, however, is able to do this very easily thanks to its ears, which are specially designed for the purpose.

The human brain uses the same method to determine the direction of sounds. The sound reaches the closer ear first, and then the one that is further away. The brain calculates the time difference between the sound reaching the two ears, and thus identifies the direction from which it came. In human beings, this calculation is performed in 10 milliseconds. The fly Ormia, however, performs the same calculation in a brain no larger than a pinhead 1,000 times faster. (1)

The designs in nature have always represented an infinite source of inspiration. Many modern technological products actually imitate designs in nature. Obviously, copying systems that have functioned flawlessly for millions of years makes things a great deal easier for designers. For example, attempts are being made to imitate the perfect design in this fly's ear in hearing aids and similar implements, under the name of Ormiaphone. Such designs, which people can only imitate, demonstrate that the power of creation belongs to God alone.


Computer Chip Warming and Butterfly Wings

There is a miracle in the design of a butterfly's wing. A study carried out at Tufts University revealed that each wing contains a special cooling system. Since butterflies are cold-blooded, they have to regulate their body temperature constantly. This represents a major problem, because as they fly, high temperatures develop in their wings. However, this problem is resolved when the blood passes through thin film-like structures in the wings. The surplus heat that forms in the butterfly's body is thus expelled as the blood flows through these delicate vessels. (2)

This special cooling system, when compared to that in computer chips, was observed to be far more efficient. As computer chip technology develops, the problem of heat worsens. Faster chips mean greater heat. The problem of eliminating this heat is being studied by computer chip manufacturers. They plan to bring the technology in butterflies' wings into production within the next two years.

Scientists model their designs according to what they see in nature. In short, the matchless systems in living things show the way to further technological progress and new solutions.


A New Objective: The Soundless Flight of Owls

The research carried out by American Air Force scientists to develop the stealth bomber airplane is based upon the matchless design found in an owl's wings. Owls can approach their prey at the dead of night without being detected due to the special design of their wings. Other bird species have rather sharp-edged wings; however, an owl's feathers have a very fine-but not at all sharp-design. This allows these nocturnal hunters to fly without making a sound.

Accor ding to statements from the NASA's Langley Research Center, an owl's soft-fringed wings prevent air turbulence, which laypeople call noise. Military designers have imitated owl wings in their quest for devising even more silent and secretive stealth bombers. (3) Each of these designs is a sign leading to faith, for it reveals the matchless artistry of God's creation.
