Edison's life

Thomas Alva Edison 1847 was born in Ohio, USA. He invented more than 2000 kinds in his life. He not only became an outstanding scientist in the history of modern physics, but also was regarded as the greatest inventor in the world. Edison's outstanding achievements in his life are not a fluke, but the result of his perseverance, courage to try and innovate. Because of his poor family, Edison received only three months of primary education and began to work on the train at the age of twelve. Even so, he studied hard and taught himself hard. When he was a teenager, he became interested in natural science. He not only mastered a wealth of knowledge of electricity and chemistry, but also liked to carry out some "small experiments" in the car and at home. 1863 worked as a waiter in a railway company, and his invention career began. With the birth of his inventions one after another, his name became familiar and his life gradually enriched.

Thomas Alva Edison (Thomas Alva Edison, 1847, February1-1931,10, 10/8). He was awarded the title of "Menlo Park Wizard" by journalists. He was the first inventor in the world who used the principle of mass production to make inventions. Edison is considered to be the most invented product in contemporary times, and he has 65,438+0,093 patents under his name. Most of the inventions are not original, but some other patents are improved, but in fact many of them were invented by many of his employees. Therefore, Edison is often criticized for not sharing these advantages. However, Edison obtained patents from many countries, including the United States, Britain, France and Germany.

Thomas Alva Thomas Alva Edison? , 1847 February1-193110 October 18), an American inventor and businessman, who developed many important devices. Menlo Park Wizard in New Jersey is the first industrial research laboratory in the world that uses the principle of mass production to produce inventions. Edison is considered to be the most inventor in the contemporary era, and he has 1093 patents under his name. Most of the inventions are not original, but some other patents are improved, but in fact many of them were invented by many of his employees. Therefore, Edison is often criticized for not sharing these advantages. However, Edison obtained patents from many countries, including the United States, Britain, France and Germany. General Electric Company was founded in 1892, and later became the largest company in the United States: General Electric Company. * * owns 244 14 patents, including Edison's 1093 patents. 1908, Edison founded the film patent company, an enterprise group composed of nine film studios. In the early 1960s, Edison bought a villa in Formel, Florida as a shelter from the cold. Henry Ford, the car king, lives opposite this villa. They remained friends until Edison died. "Edison and Ford Winter Manor" is currently open to the public. Thomas Edison was born in Milan, Ohio, USA. He is the seventh son of Sam and Nancy. Because of illness, Edison studied in an evening school. His habit of asking questions and thinking made the school teacher very angry and called him "Jia&; ; quot。 This made Edison only receive three months of school education. Edison's mother Nancy is a teacher in Canada. She happily took Thomas home, taught herself, taught knowledge in her own way, and encouraged him to study and do experiments. From this moment on, Edison's life was completely rewritten. He later recalled, "I made my mother. She is sincere, I'm sure; I think I need to live a meaningful life, so I can't let her down. "[1] A lot of his knowledge comes from R.G. Bogart's school of natural philosophy. Edison began to suffer from hard of hearing when he was 12 years old. It is said that the train controller grabbed him by the ear and dragged him to the moving train, causing deafness. [2] Edison lived a bittersweet life in Port Huron, Michigan. He works as a newsboy on the train between Port Huron and Detroit.

Selling newspapers and candy. He has been partially deaf since he was young. He saved Jimmy in a train collision? Mackenzie later became a communications operator. Jimmy's father

J.U. Mackenzie, the stationmaster of Clemens Station, was very grateful to Edison.

And trained him to be a telegraph operator. Edison's deafness helped him cover up the noise.

And prevented Edison from hearing the operator sitting next to him. In the early days,

One of his mentors is a telegraph operator and an inventor.

Called Franklin? Leonard. Pu. He allowed poor young people to live and work in Elizabeth's basement. Some of his earliest inventions were related to the electronic telecommunications law, including the stock quotation machine. Edison applied for his first patent on1October 28th, 1868.

Edison began his career as an inventor in Newark, New Jersey. He improved automatic repeaters and other telex equipment, but the first invention that made him famous was the phonograph of 1877. This achievement surprised the public and seemed almost unbelievable. Edison became famous in The Wizard of Menlo Park in New Jersey where he lived. His first tin foil tube recorded the sound quality of the phonograph, and destroyed the audio track during the replay, so that he could only listen to it a few times. In 1980s, Alexander Graham Bell, chichester Bell and Charles tainter designed a waxed and painted cardboard cylinder model. This is one reason why Edison kept making his "perfect phonograph". Edison was a free thinker and probably a deist. He doesn't believe in "the God of theologians", but he doesn't doubt "supreme wisdom". However, he rejected supernatural thoughts and souls, immortal thoughts, and personal God. He said: "Nature is not kind and loving, but completely cruel and indifferent. Moderns US Patent #223898 Electric Lamp 1878 In new york, Edison and several financiers including J·P· Morgan and Vanderbilt established Edison Electric Lamp Company. Edison demonstrated incandescent light bulbs for the first time in Menlo Park on1879 65438+February 3 1. 1880,65438+1Oct. 27th applied for a patent for incandescent lamp in the United States. Then he said, "We will make electricity cheaper, and only the rich will light candles. [Source Request] 1883,/kloc-0 10 On October 8th, the US Patent Office ruled that Edison's patent was based on the work of William Sawyer, so it was invalid. The lawsuit lasted for almost six years, until June 6, 1889+ 10, when the judge ruled that Edison's request for electric light improvement was legal. In order to avoid a possible lawsuit with Yue Se Swan, he and Swan set up a joint venture company named "Eddis Swan" in Britain to sell inventions. Other inventors who designed electric lamps included Serbian inventor nikola tesla, who wanted to ignite radio bulbs from side electrodes by radio frequency electroplating under the Tesla effect. He also plans to develop a wire to refocus energy from the glass shell back to the center of the light bulb, and then use the center "button" to emit incandescent light to ignite the light bulb. Although Tesla invented fluorescent lighting, Edison's design won at this time. . Edison obtained the patent of power distribution system in 1880, which was very important for the invention of electric light. My first investment in all electrical industries was 1882 new york Pearl Street Station. 1On September 4th, 882, Edison opened the world's first power distribution system at Pearl Street Power Station, providing 1 10 volt direct current (DC) to 59 customers in lower Manhattan. On June 9, 2009, the first standardized incandescent lamp system using top wires was put into use in Roselle, New Jersey. . Carbon electrode telephone transmitters 1877 and 1878 Edison invented and developed carbon electrode microphones and bell receivers, which were used in all telephones until the 1980s. After a long patent lawsuit, the federal court ruled that Edison, not Amy Berlin, was the inventor of 1892 carbon electrode microphone. (Josephson, P146). In the 1920s, carbon electrode microphones were also used for radio broadcasting and broadcasting. Photo: PyramidParthenon's luxurious electric light display soon became a public feature. This picture was shown at 1897 Tennessee Centennial Expo. Because Edison promoted direct current (DC) to transmit electricity more easily, and George? Westinghouse sells the alternating current (AC) system developed by Tesla, and Westinghouse and Edison become enemies. Unlike DC, alternating current can reach a very high voltage through a transformer, send it to a young conductor, and then reduce the voltage at the destination. Although Edison thought contempt was the main blow, the war with alternating current led Edison to participate in the development and promotion of electric chairs to show the greater lethal potential of alternating current to "safer" DC. Edison launched a short but powerful campaign to ban the use of alternating current, or to limit the allowable voltage for safety purposes. As part of this campaign, Edison showed dogs, cats and an elephant that were electrocuted to show the danger of alternating current. Tesla's AC has replaced DC's power generation and energy distribution in many cases, which has great extensibility and improves the safety and efficiency of energy distribution. Although DC finally lost its power distribution advantage, it is still mainly used in long-distance HVDC transmission systems.
