? Introduce Edison's life and personal achievements as the father of invention.

Thomas Alva (English name: Thomas Alva Edison, 1847-193 1 year), a world-famous economist, physicist and entrepreneur, holds many well-known and important patents, and was awarded the title of "the wizard of Monroe Park" by the media! He is the first person in human history to use a large number of production principles and electrical engineering research laboratories to engage in patents, which has a significant and far-reaching impact on the world. & gt There are more than 2,000 inventions, including phonograph, movie camera, tungsten light bulb and so on, which have great influence on the world. In the United States, Edison has 1093 patents, while his patents in Britain, France, Germany and other places have accumulated more than 1500. & gt Edison is one of the famous geniuses in the history of technology, with 1093 invention patents for incandescent lamp, phonograph, film projector and camera. Among them, Edison's four great inventions: the phonograph, the electric light, the electric power system and the talking film have enriched and improved the civilized life of mankind. & gt Personal Achievements: >1In the spring of 876, Edison moved to Menlo Park, New Jersey again. He built the first "invention factory" here, which "marked the beginning of collective research". In the same year, Edison established his experimental invention center in Menlo Park in the south of new york, which is what we generally call Edison's invention factory. There are excellent equipment and instruments here, as well as a group of talented experts. During the period from 1876 to 1887, this group of scientists headed by Edison carried out systematic, in-depth and complicated scientific research and development work here. If we make a list of Edison's inventions in Menlo Park, I'm afraid the form will extend from the table to the ground. There are many unfamiliar items in it, but many of them are closely related to our lives. > > telephone, telegraph and phonograph > 1877, Edison improved the telephone invented by Bell and put it into practical use. He also invented the phonograph, which is one of his favorite projects. & gt The telephone and telegraph are "a revolution to expand human sensory functions", and the phonograph is "one of the three great inventions that changed people's lives". "Judging from the imagination of the invention, this is his extremely significant invention achievement". At this time, people called him "the magician of Monroe Park". > When Edison invented the phonograph, he finally made a breakthrough in the study of electric light after numerous failures. 1879, 10 year1October 22nd, Edison lit the first electric lamp with wide practical value. In order to prolong the life of the filament, he experimented again and tried more than 6000 kinds of fiber materials before finding a new luminous body-Japanese bamboo filament, which can last for more than 1000 hours and achieve the purpose of durability. To some extent, this invention brought Edison to the pinnacle of his life. Then, he established new power supply system facilities, so that distant household appliances can distribute electricity from the central power station, which is an important achievement in the process of power transmission. > electric light (Edison effect) > his first discovery in pure science appeared in 1883. When he experimented with electric lamps, he observed what he called the Edison effect: there was a charge in a lighted electric lamp passing through space from a hot filament to a cold plate. Edison applied for a patent for this discovery in 1884, but did not do further research. On the other hand, other scientists continue to use the Edison effect to research and develop the electronic industry. > film industry Edison tried to do for his eyes what the phonograph did for his ears, and movie cameras and movie projectors appeared here. Using a piece of celluloid film newly invented by George Heasman, he took a series of photos and projected them on the curtains in rapid succession, creating the illusion of movement. He experimented with movies for the first time in the laboratories of 1889 and 189 1. 1903 His company produced the first feature film great train robbery. Edison did a lot of work for the integration and standardization of the film industry. After Edison moved his laboratory to West Orange in 1887, he founded many commercial companies to promote his inventions. These companies were later merged into Edison General Electric Company, which was later called General Electric Company. > other inventions > since then, his interest has shifted to fluorescence, ore masher, magnetic separation of iron, storage battery and railway signaling device. During the First World War, he also developed torpedo mechanism, catapult and underwater periscope. & gt& gt's marriage and family led Edison to start the experiment of transforming the arc lamp in 1877, and proposed to divide the current and change the arc lamp into white light. The experiment should reach a satisfactory level. It is necessary to find a substance that can burn to white heat as a filament, and can withstand high-temperature combustion of more than 2000 degrees 1000 hours. At the same time, the usage should be simple, can withstand the impact of daily use, and the price should be low. It is also necessary to turn on and off one lamp without affecting the turn-off of any other lamp and maintain the relative independence of each lamp. This was a very bold idea at that time, which required great efforts to explore and experiment. > In order to explore this kind of filament material, Edison first experimented with carbonized materials, and then failed to experiment with platinum-iridium alloy with high melting point. He also made 1600 different experiments with fine ores and seedlings, all of which failed. But at this time, he and his assistants have made great progress. They know that incandescent filament must be sealed in a glass ball with a high vacuum so as not to burn easily. In this way, his experiment returned to carbon wire. He studies and experiments day and night. By the first half of 1880, Edison's incandescent lamp experiment was still inconclusive. Three years have passed since his experimental notebooks reached more than 200, with a total of more than 40,000 pages. He works eighteen or nine hours a day. At three or four o'clock every morning, he only sleeps under the experimental table with two or three books on his head. Sometimes he sleeps on the stool three or four times a day for only half an hour at a time. & gt By the first half of 1880, Edison's experiment with incandescent lamps was still inconclusive, and even his assistants were discouraged. One day, he tore a bamboo filament tied to the edge of a banana fan in the laboratory into filaments and carbonized it into filaments. The result is better than all previous experiments. This is Edison's first incandescent electric lamp-bamboo filament electric lamp. This kind of bamboo filament lamp lasted for many years. It was not until 1908 that tungsten was invented as a filament and was replaced. Edison began to develop alkaline batteries after this, which was very difficult, and his research spirit was even more amazing. This kind of battery is used to provide power. & gt He and a selected assistant have studied hard for nearly ten years and experienced many hardships and failures. One moment he thought he had reached his destination, but the next he knew he was wrong. But Edison never wavered and started again. It took about 50,000 tests and 150 test notes to achieve the goal. & gt Edison studied hard all his life, was good at thinking and worked hard. At the age of 75, he even signs in for work in the laboratory on time every day. For decades, he worked almost ten hours a day and spent three to five hours reading in the study at night. If you spend the average person's life time, his life has doubled. So, on his 79th birthday, Edison proudly told people that he was 135 years old. & gt When he lived to be 84 years old, he invented as many as 1 100, among which the greatest contribution was the invention of the phonograph and the automatic telegraph, and the experimental improvement of incandescent lamps and telephones. Edison began to study electric light in his early twenties, which lasted for 10 years. He chose thousands of different substances, such as bamboo, cotton, graphite and tantalum, as filament materials for experiments, and often stayed up all night. Once he and his assistants worked continuously for five days and five nights. 1879 Edison used bamboo carbon filament as incandescent filament and lit it for 40 hours. Because the surface of carbon wire is porous and fragile, its strength is very low. 1908 and then replaced with tungsten wire. & gt
