The mother-of-pearl's special structure that decreases damage
Harun Yahya
In the development of materials to be used in the production of strong impellers in jet engines, the mother-of-pearl’s structure is imitated. 95% of the mother-of-pearl on the inner layer of many shellfish’s shells is chalk, but mother-of-pearl is 3,000 times stronger than chalk thanks to its composite structure. When this structure is examined, it is seen that microscopic tablets, only eight microns (1 micron=10–6 meters) in width and one half of a micron in depth, are arranged as layers. These tablets are a dense, shiny crystalline form of calcium carbonate. But the combination of these tablets is only possible with a silk-like sticky protein.
This combination ensures a two-way hardness. First, the breaks that form when a heavy load is placed on the mother-of-pearl naturally moves along the thinnest layers, yet they change direction when they try to pass the protein layers. This distributes the applied force and thus a complete break-up is prevented. A second strengthening factor is that the protein layers tighten along the cracks when a crack is formed. By means of this tension, the energy that will resume the break is dispersed.
This special damage decreasing structure of the mother-of-pearl has become a subject of research for many scientists. The fact that matter in nature has gained resistance with such intelligent methods points to the existence of the Owner of a superior intelligence. As can be seen from this example, Allah shows us His existence and the evidences of the superior strength and mightiness in His Creation with His infinite knowledge and intelligence. Therefore, the praise for the order here is for Allah, as it is in all things. In one verse, Allah reveals as such:
"His is whatsoever is in the heavens and whatsoever is in the earth; an most surely Allah is the Self-Sufficient, the Praised." (Surah al-Hajj, 64)
The Superior Creation in Bats Teaches Us How to Be Safer in our Cars
Researchers at the University of Edinburgh have conducted studies on a robot, which has “smart ears” to find its way via eco-location (using the sound waves emitted by some creatures to detect things such as the distance or size of an object) just like a bat. Jose Carmena, from the informatics faculty of the university, and his co-workers have named this robot as “RoBat.” A sound source that acts like a mouth and two fixed sound detectors were placed on RoBat. Then the robot’s mouth was arranged to spread sound waves (echos) just like in bats.
In the design of RoBat, other characteristics of bats were also considered to utilize the echos in the best way possible. Bats move their ears to determine the frequency intervals of sound waves, and in this way they easily overcome the obstacles in front of them and find their prey and catch it. RoBat was also equipped with such ultrasonic detectors to have a perfect mechanism like that seen in bats.
By means of such sound detectors, designed by inspiration from nature, it is thought that roads and highways will become safer one day.
However the leading car manufacturers of the world are using ultrasonic detectors that are activate when the vehicle is put into reverse gear. The driver is therefore able to recognize how close he is to another car or object standing behind him, thanks to these detectors.
These superior beings, of which we can give a few examples, and which serve as an inspiration to the technological advances of the 21st century are only some of the works of Allah, Who creates all things without prior example and in a perfect manner. In the Qur’an, Allah’s name “Al-Badi (One Who Creates without example)” is revealed as follows:
"He is the Originator of the heavens and the earth.…" (Surat Al-An‘am, 101)
