The world of living things (Nature) had it first

Nature is our best instructor.

By Milton Bertrand

If we were to ask, who first demonstrated a handheld cellular telephone? We could have various answers to this question. The first handheld cellular telephone was demonstrated by Dr. Martin Cooper on the street of New York in 1973. The telephone’s components were a battery, a radio, and a microprocessor. It was an amazing moment for the people to see Dr. Cooper made a phone call on the street. This phone call could have not made possible if in the 1800 Alessandro Volta did not invent a reliable battery. In Addition, the telephone had been developed by 1876, the radio by 1895, the computer by 1946.To make all that possible was with the invention of microprocessor in 1971. After all, we may still wonder and ask is communication really new?

Some people may argue yes while others may say no, or stay neutral. Indeed, a major communication device that is often taken for granted is the human voice. To make all that possible a cascade of events is taking place in the brain. In the motor cortex over half billions of the neurons are involved in controlling the speech. About 100 muscles control the complex mechanism of the tongue, lips, throat, chest and every other organ that needs to be used in speech.

The ear plays a major part in the communication; its role is to convert sounds into electrical impulses that the brain can understand and process. In addition, the brain analyzes the sounds so that people can recognize different type of sounds. Also the brain measures and calculates exactly where a sound is coming from. The brain is such a complex machine it enables us to listen and pay attention to one person at a time despite that several others are speaking. At the microscopic level we come to understand how the cells divide to make new ones. The eye is like a television camera. It captures images and converts them into electrical signals and transmits them along the opposite nerve to the back of the brain, where the actual seeing is taking place.

In conclusion, all the sophisticated devices that are engineered are not new; if we take a close look around us we can find them all in nature. The world of living things (Nature) had it first.
