In 1855, he started school. There was only one class in that school, and the principal and teacher were both Mr. Engel. Because Edison had an inquisitive nature, he often asked the teacher some unusual questions during class (such as: how is the wind produced? Why does one plus one equal two instead of four). In just three months, he was dismissed by the teacher as Kicked out of school in the name of "imbecile".
Because her mother Nancy was a teacher at a girls' school at the time and was a person with rich educational experience. She did not think that her children were "imbecile", so Nancy taught Edison herself. According to Nancy's careful observation on weekdays, Edison was not only not an "imbecile", but also often showed talent.
Nancy often asked Edison to do experiments by himself. Once when talking about Galileo's "Leaning Tower of Pisa Experiment", Nancy asked Edison to try it on the tall tower next to her home. Edison took two Balls of different sizes and weights were thrown from a high tower at the same time. As a result, both balls landed at the same time. Edison felt it was amazing and excitedly told his mother the results of the experiment. This experiment was also etched in Edison's mind.
Because of his mother's good education methods, Edison realized the importance of books. Not only was he well-read, he also had a photographic memory. Under the guidance of his mother, Edison read the works of the British Renaissance playwrights Shakespeare and Dickens and many important historical books, such as Edward Gibbon's "The Decline and Fall of the Roman Empire" and David Hume's "History of Britain". After reading some of Thomas Paine's works, Edison was attracted by the insights in the books, which continued to influence him throughout his life.
In 1857, Edison began to become interested in chemistry. He conducted experiments according to textbooks in the cellar of his home, and often caused frequent accidents.
In 1859, in order to have enough money to buy chemicals and experimental equipment, Edison began to look for a job to make money. After some hard work, he found a job selling newspapers on the train, traveling to Port Huron every day. Between Detroit and Detroit, he sold newspapers and carried fruit and vegetable business, but whenever he had time he would go to the library to read.
In 1861, Edison used the money he earned from selling newspapers to buy an old printing press and began to publish the weekly Herald, which he edited. The first issue was printed on the train. He was both the president and the publisher. Journalist, publisher, but also printer and newsboy.
There was a rest room on the train where Edison worked because the air was not circulating, so no one went there to rest and it became an empty room. Because Edison was running around on the train every day and came home very late every day. He often felt that there was not enough time. Edison thought that if the rest room was converted into a laboratory, he could conduct experiments on his way back to Port Huron. With the consent of the train conductor, the empty lounge became Edison's laboratory.
Although doing experiments is much more convenient, accidents often happen. Once, the chemicals in his laboratory suddenly caught fire, causing damage. The conductor threw his experimental equipment out of the car in anger. .
One day in August 1862, Edison rescued a boy on the train track, and the child's father was the stationmaster Mackenzie. He was very grateful for this and taught Edison the telegraph. Technology, under the guidance of Mackenzie, Edison learned telegraph technology and sent his first telegram.
At the end of 1868, Edison came to Boston as a telegraph operator. In the same year, he obtained the first invention patent, which was a device for automatically recording the number of votes, also known as a "vote counter." Edison Thinking that the device would speed up the work of Congress and be popular, a congressman told him that sometimes voting slowly was politically necessary, so Edison decided never to create an invention that people didn't need again.
In the late autumn of 1869, Edison came to New York alone to look for a job. However, when he was looking for a job in a company, he happened to encounter a broken telegraph machine there. Edison quickly repaired the telegraph machine. The telegraph machine was appreciated by the general manager, and he became the chief telegraph technician. He had a stable working environment and salary, which provided good conditions for his future inventions.
In October of the same year, Edison and Franklin Pope jointly founded the "Pope-Edison" company, specializing in scientific instruments for electrical engineering, and at the same time invented the ordinary printing press.
In 1870, Edison sold the patent rights for a general-purpose printing press to a Wall Street company and asked the manager to pay a price. He originally wanted to ask for a few thousand dollars, but the manager actually gave Edison Forty thousand dollars. After Edison received $40,000, he built a factory on Ward Street in Wacker, New Jersey, to manufacture various electrical machinery.
In 1873, Edison invested in the research of synchronous transmitters.
In December 1874, when the research work on the synchronous transmitter was coming to an end, Western Union agreed to pay Edison US$5,000 and offered US$25,000 to purchase the patent. It also paid him US$233 per day as a There was a fee per line to use this equipment, but Western Union failed to fulfill its agreement. In the end, Jay Gould purchased the patent for the synchronized transmitter for $30,000, allowing Edison to tide over the difficulties.
At the end of 1875, Edison was about to welcome the birth of his second child. He felt that the space at home was too narrow. The narrow, dark streets and noisy environment where the Newark factory was located also affected the work of researchers. Emotionally, Edison finally made up his mind to move.
In early 1876, the Edison family moved to Menlo Park, New Jersey, where he built a laboratory.
In 1877, Edison improved the early telephone invented by Alexander Bell and put it into practical use, and soon opened a telephone company. Two rival companies, Edison and Bell, competed fiercely in London.
In the process of improving the telephone, he found that the diaphragm in the microphone vibrated with the sound of the voice. He found a needle, stood it upright on the diaphragm, and gently pressed the upper end with his hand. Then speaking to the diaphragm, the speed of the sound can cause the short needle to vibrate in different ways. Edison drew a sketch for this and asked his assistant to make the machine. After many modifications, the first phonograph was born.

On October 21, 1879, the American scientist Edison invented the electric light, also known as the incandescent lamp, which is a kind of electric light that uses resistance to heat fine wires to Incandescent, a lamp used to emit light. Edison was the world's first inventor to use the principles of mass production and his industrial research laboratories to produce inventions. Edison has more than 1,500 patents in his name. Founded General Electric Company in 1892.
An electric light bulb, or electric bulb, its precise technical name is an incandescent lamp, is a lamp that uses electricity to heat a fine wire (usually tungsten wire in modern times) to incandescence by using resistance to emit light. . The periphery of the light bulb is made of glass, which keeps the filament under vacuum or low-pressure inert gas to prevent the filament from oxidizing at high temperatures.
It is generally believed that the electric light was invented by American Thomas Edison. But if there is serious research, another American, Henry Goebbels (Heinrich G?bel), had invented the same principle and material and a reliable light bulb decades earlier than Edison. Before Edison, many other people had also invented the electric light bulb. He has made many contributions to inventions.
In 1801, the British chemist David electrified platinum wire to produce light. He also invented the electric candle in 1810, which used arc lighting between two carbon rods. In 1854, Henry Goebbels used a carbonized bamboo filament and placed it under a vacuum glass bottle to energize it and emit light. His invention appears today to be the first practical incandescent light bulb. The light bulb he tested at that time could last for 400 hours, but he did not immediately apply for a design patent.
