1. I like invention the first phone invented in 1876 by Alexsander Graham Bell marked the development of the mobile era of man. The first mobile phone was named Motorola DynaTAC and weighed about 1 pound, it had the basic functions of listening, calling and dialing, but the price of a DynaTAC was not cheap at all. You will have to spend $ 3,500 to own this phone.

Science and technology has become a debated topic in the society. One hand, it is necessary for the modern life where other countries are continuously developing in the field of science and technology. It becomes very necessary for other countries too to grow in the same way to be strong and well developed like other countries for the future safety and security. It is science and technology which helps other weak countries to develop and be strong. We have to take support of science and technology forever to improve the way of life for the betterment of mankind. If we do not take the help of technologies such as computer, internet, electricity, etc we cannot be economically strong in the future and would be backward forever even we cannot survive in such a competitive and technological world.
