Who is Edison?

Thomas? Alva? Edison (1847-1931) is the greatest inventor in America. He is famous in history for opening up a way to combine technology development with scientific research.

Extraordinary childhood Edison was born in Milan, Ohio, USA, to a Dutch immigrant family on February 11th, 28. When Edison was a child, his first teacher only knew how to wave a pointer and cram knowledge into the child's mind, without paying attention to methods at all. Later, Edison was expelled from the school because of what the teacher called "mental defect", so his mother had to take the responsibility of educating her son to read, but her education method was completely different from that of the school: whenever there were stars all over the sky, she led her son to climb the observatory and sometimes told stories about the rise and fall of the Roman Empire; Sometimes I read classical literary works such as Robinson Crusoe ... Through the influence of these literary arts, Edison's thinking and imagination have been greatly improved, which laid the foundation for him to become a great inventor in the future.

Edison's family was poor. At the age of 12, he got a job selling newspapers on the train. At that time, he sold newspapers and did fruit and vegetable business. Whenever he had time, he went to the library to read books. He also bought an old printing press, started publishing his weekly newspaper, The Herald, and used the money he earned to set up a chemical laboratory on the luggage cart. Unfortunately, once a chemical caught fire, it was slapped by the train conductor and thrown out of the car, which caused Edison to lose his hearing in one ear.

Edison made his first invention-electronic voting recorder when he was 23 years old, but this instrument didn't bring Edison any economic improvement because it didn't sell. However, shortly after he invented the recorder, Edison invented an automatic recorder to improve the stock market and exchanged it for 4 thousand dollars, which was a huge income at that time.

Flash Achievements Later, Edison made a series of other inventions, and soon he gained fame and fortune. Perhaps the most creative invention in his life was the phonograph, which he patented in 1877. But what is more important to the world is that he invented a practical incandescent light bulb in 1879.

Edison established the first transmission company to send electricity to private homes, which laid the foundation for the development of a huge industry. Edison made great contributions to the development of movies, cameras and projectors. He made important improvements to the telephone (his carbon microphone significantly improved the audibility), telegraph and typewriter. Among his other inventions are the phonograph, mimeograph and storage battery. Altogether, Edison obtained more than 1 patents for single inventions, which is really an incredible number.

Edison's contribution to society is obvious to all. He is a genius, the greatest invention genius that has ever appeared. Edison was obsessed with inventions, and he officially registered 1328 kinds of inventions, known as the king of inventions in the world. His invention depends not only on intelligence, but also on hard scientific practice. For example, when he invented the electric light, he used 2 notebooks to collect information alone; In order to find a suitable filament, more than 16 kinds of materials such as copper wire and platinum wire have been used, as well as hair and various kinds of bamboo wires. Finally, a Japanese bamboo wire was selected and became the original filament after burning and carbonization. To achieve such a great achievement, in addition to a curious heart and an instinct to experiment by himself, he has the infinite energy and courage to work hard beyond ordinary people. His success is just like what he said: "Invention is one percent inspiration and ninety-nine percent perspiration.
