Alexander Graham Bell

The telephone was invented by a Scottish teacher of the deaf named Alexander Graham Bell. His great invention was really amazing. It is a very great use for the mankind in the world.Alexander Graham Bell was born in Edinburgh, Scotland, in the nineteenth century. In 1871, he came to the United States. Several members of his family did a great deal to encourage him in the field of science. He began his experiments by trying to invent the harmonic telegraph.

Through an accident, he invented the telephone. On 10th March 1876, Thomas A. Watson, Bell’s assistant, became the first person ever to hear words spoken over the telephone. At that time, Bell and Watson were testing a crude telephone transmitter. Watson was waiting for the test message at the end of the wire in another room. Suddenly, Bell spilled battery solution on his clothes. He called out his assistant, “Mr. Watson, come here, I want you!”

Then, Watson rushed into the room and shouted, “Mr. Bell, I heard every word you said – distinctly!” The telephoned had worked. The damage to Bell’s clothes was forgotten. The receiver and transmitter of Bell’ first telephone could be used interchangeably. Afterwards, he exhibited his instrument at the Centennial Exposition at Philadelphia in June, 1876. The public at first showed little interest, but scientists greeted it with enthusiasm.

The first money ever paid for the lease of a commercial telephone was paid in May, 1877. By August of that year about 800 telephones were in use.The first telephone line was installed between Boston and Somerville, Massachusetts in April 1877. The first commercial telephone exchange was opened by George W. Coy on 28th January 1878, in New Haven, Connecticut.

Bell’s life was dedicated to a science. His very great invention is very useful for the world communication i.e. telephone.

Galileo Galilei (1564-1642) — Astronomer and Scientist. Galileo developed a superior telescope and made many significant discoveries in astronomy. He was sentenced to life imprisonment by the inquisition for his support for the Copernican theory that the sun was at the center of the solar system.

Galileo was born in Florence, Italy in 1564 to a poor but noble family His parents recognized their child’s innate intelligence and talents and so made sacrifices to have him educated. At his father’s insistence, Galileo studied the profitable career of medicine. But, at the University of Pisa, Galileo became fascinated in a wide range of subjects. He was also critical of many of Aristotle’s teaching which had dominated education for the past 2,000 years.

Galileo was appointed to be a mathematics professor at the University of Pisa, but his strident criticisms of Aristotle left him isolated among his contemporaries. After three years of persecution, he resigned and went to the University of Padua, where he taught math. His entertaining lectures attracted a large following and he was able to spend the next 18 years pursuing his interests in astronomy and mechanics.

Alfred Bernhard Nobel was a Swedish chemist, engineer, innovator, and ornament manufacturer. He was the inventor of dynamitE. He also owned Bofors, which he had redirected from its previous role as primarily an iron and steel producer to a major manufacturer of cannons and other ornaments. He held 355 different patents, dynamite being the most famous. In his last will, he used his enormous fortune to institute the Nobel Prizes. The synthetic element nobelium was named after him. He was the third son of Immanuel Nobel and Andriette Ahlsell Nobel. Born in Stckholm on 21 October 1833, he went with my family to Saint Petersburg in 1842, where his father invented modern plywooD. He studied chemistry with Professor Nikolay Nickolaevich Zinin. When he was 18, he went to the United States to study chemistry for four years and worked for a short period under John Ericsson, who designed the American Civil War ironclad USS Monitor.

Returning to Sweden, with his father after bankruptcy of his family business, he then devoted himself to the study of explosives, and especially to the save manufacture and use of nitroglycerine (discovered in 1847 by Acanio Sobrero, one of his fellow students under Theophile-Jules Pelouze at the University of Turin).
