Biografi Alexander Graham Bell

Biografi Alexander Graham Bell. Not how can formal education, but taught well by his family and taught myself, so the particulars tilpun inventor Alexander Graham Bell who was born in 1847 in Edinburgh, Scotland. Interest in Bell reproduce vocal sounds reasonably incurred because of his father an expert in terms of vocal physiology, improving speech and teach deaf people.
Bell had been to Boston, the state of Massachusetts in 1871. It was there in 1875 he made experiments which led to the discovery tilpun. He gathered a patent to establish the alleged discovery in February 1876 and received in return a few weeks later. (It is interesting to note that another man named Elisha Gray also garnered a patent invention for strengthening of similar equipment on the day that coincided with what was done Bell, the only difference a few hours only).

Shortly after the patent is received, Bell tilpun at the exhibition showing 100 years the city of Philadelphia. His discovery attracted the attention of the public and received an award for their work. However, The Western Union Telegraph Company that offers a money of $ 100,000 for the invention of it evaded paying. Because of that, Bell and his friends, in July 1877, started his own company, the ancestors of the American Telephone and Telegraph Company now. Tilpun quickly and achieve massive commercial success. This Sakarang AT & T is the largest business enterprise in the world.

Bell and his wife are in the month of March 1879 holds 15 percent shares of the company apparently had no idea how to fantastic benefits that would be received by the company. Within just seven months, they've sold most of their stock at a price averaging $ 250 per share. In November the price had shot up to $ 1000 per share! (In March it was the one who urged his wife rush sale because he was worried about the stock price would not be that high again!) In 1881 they sold more hastily-third of the remaining shares they hold. Even so, yet in 1883 they were able to get benefits worth about a million dollars.

Although the invention has been orbiting Bell tilpun so wealthy, he never stopped to continue its investigation, and he managed to find again the various tools that are useful, though not as important as tilpun. His interests varied, but its main purpose is to help the deaf. His own wife was deaf girl who practiced alone. Four children, two boys two girls came out thanks to the marriage but the fourth died young. Bell finished in 1882 U.S. citizen and died in 1922.

Large-small effect size lies in the assessment of Bell's size tilpun meaning itself. In my opinion, influence is enormous because there are so many discoveries are widely used by people and so great influence in everyday life.

Bell in the order I placed under the Marconi radio since its usefulness is more diverse than tilpun. For example, conversations tilpun can basically be done by radio, but in some ways (eg communication with aircraft in flight) tilpun can not replace the function of the radio. If it's just that factor alone is so the size, Bell will occupy much further down the order again than Marconi. However, there are two things worth considering. First, although the private tilpun conversation could have been done over the radio, it would be extremely difficult to replace the entire system pertilpunan us with the equivalent of a radio network. Second, the principal method of distributing re-designed sound for the Bell receiver oper tilpun lately taken and used by a radio receiver, phonograph records and various other equipment form. That's why I consider the influence of Bell just slightly less than the Marconi.
