American inventor. In history, it is famous for establishing factory laboratories and opening up ways to closely combine technology development with scientific research. 1847 February 1 1 Born in Mylan, Ohio, a Dutch immigrant family. 193 1 year1October 18 died in west orange, new jersey. I had only three months of formal education when I was young. From the age of 12, he worked as a newsboy, vendor and telegraph operator to make a living. Influenced by M Faraday, he engaged in electrical experimental research and invention all his life. 1868, he invented a ballot recorder and tried to sell it to congress, but it was not adopted. Edison's first invention did not find a market, which made him pay more attention to the practicality of the invention. 1869, Edison moved from Boston to new york. He improved the telegraph of Gold Index Telegraph Company, which was appreciated by the company manager and was hired with a monthly salary of 300 dollars (which was a very high monthly salary at that time). 1870, he moved to New Jersey and began his period of efficient invention. 1874 improved the typewriter. 1876, a carbon microphone was added to the telephone invented by a g bell, which improved the reception of sound.
1876, he founded his own famous laboratory. In this laboratory, he broke the tradition that a single scientist engaged in research alone, and organized a group of professionals (including N Tesla and others) who worked together to formulate topics and assign tasks, and worked together on an invention, thus creating the correct way of modern scientific research. 1877, he invented the phonograph and made him famous all over the world. 1878 started the research of incandescent lamp. After more than ten months of repeated failures, the incandescent carbon filament lamp was successfully lit on June 1879 and June 65438+1October 2 1, and it was lit stably for two whole days. 1882, the world's second public thermal power plant was established in Pearl Street, new york, and the electric lighting system in new york was established, which became the prototype of modern power system. The realization of electric lighting not only greatly improves people's production and working conditions, but also indicates the arrival of the electrification era of daily life. 1883, when Edison was testing a vacuum bulb, he happened to find a current passing between the cold electrode and the hot electrode. This phenomenon was later called Edison effect, which became the basis of electron tube and electronic industry. 1887, he moved to west orange, and in the same year, he founded a larger laboratory with updated equipment in the city, namely the famous Edison laboratory (later called the invention factory). Here, according to the invention of G. Hysmans, I made my own camera. 19 14 years, the earliest sound film system was made with phonograph and camera. In his later years, his inventions and innovations included batteries, cement mixers, recording telephones, duplex and multiplex telegraph systems and railway brakes. During the First World War, he was the chairman of Ren Haijun's Technical Advisory Committee, directed the research on torpedoes and anti-submarine equipment, and invented dozens of weapons. To this end, the US government awarded him the 1920 Medal of Outstanding Service, and the French government awarded him the Legion of Honor. 1928, the US Congress awarded him the Medal of Honor. Edison and his laboratory obtained 1093 invention patents all their lives. Edison made many inventions in his life, but after all, he lacked systematic scientific knowledge, so he could not make a correct judgment on the development of modern technology. At the end of 19, AC transmission system appeared, but he still insisted on DC transmission, and lost the contract to build Niagara Hydropower Station in the fierce competition with G. westinghouse; His laboratory blindly trial-produced magnetic mineral processing equipment, exhausted the funds obtained from the invention of electric light, and finally had to give up. However, Edison's contribution to the development of electric power, the manufacture of electrical appliances and the popularization of electric energy applications made him one of the greatest inventors in human history.
Edison (1847~ 193 1), Thomas Alva, American inventor. The establishment of the factory laboratory, the development of technology and the opening of scientific research are all closely related to this eternal history. February 1 1, 1847 A Dutch immigrant family in Medan, Ohio. 1October 18, 193 1 Xiaolan in New Jersey is dying. Only received three months of formal education. /kloc-at the age of 0/2, he worked as a Bao Tong, a vendor and a reporter, and made his own living. Because of m.
Faraday effect in life science research experiments and inventions. 1868 He invented a recording device and sold it to Taiwan Province's parliament for voting, but it was never used. Edison's first invention prevented him from finding that the market paid more attention to the relevance of this invention. Edison moved from Boston to new york. He improved the telegraph index of the telegraph company and was recognized by the company manager. He was hired with a monthly salary of $300 (which was a high salary at that time). 1870, moved to new jersey to start his efficient invention period. 1874 improved typewriter. 1876, to the latter.
Bell invented the telephone with carbon harvesting route and put forward the word "beep". 1876, founded his famous laboratory. In the laboratory, he broke the tradition that a single scientist engaged in research in the past and organized a group of professionals (including N.
Tesla and others), and the theme of his mission, worked together to invent, thus creating the correct method of modern scientific research. 1877, invented the phonograph, which made him original. 1878, this research started after the incandescent lamp failed many times in 10 month. 10/2 1, 1879 lit the carbon filament lamp at the successful position of the incandescent lamp, and the position was stable between two days. 1882, the public fire protection of Pearl Street block in new york is the second factory in the world, which was built in new york City Lighting and Electric, and the modern power system has begun to take shape. The achievement of Mar lighting not only greatly improves the working conditions of production, but also indicates that an era of electrification of daily life is coming. 1883, Edison happened to find a current hot electrode on the cold electrode during a vacuum bulb test. This phenomenon is called Edison effect, which is synonymous with electron tube and electronic industry. 1887, from Xiaolan government, and in the same year in a larger city, the laboratory equipment was also updated to the famous Edison laboratory (later called the invention factory). Here, according to g.
The school invented and produced its own cameras. 19 14, the first sound system made of phonograph and photographic film. In his later years, his inventions and innovations included batteries, cement mixers, recording telephones, double and multi-type cable systems, and brakes for railways. During the First World War, he served as the chairman of the Technical Advisory Committee, directed the research on torpedoes and anti-submarine equipment, and invented dozens of weapons. To this end, the US government awarded him the Medal of Outstanding Service on 1920, and the French government awarded him the Legion of Honor. 1928, the US Congress awarded him the Medal of Honor. During their whole life cycle, Edison and his laboratory obtained 1 093 invention patents. Edison invented many things in his life, but he was a scientific knowledge system after all, so he could not make a correct judgment on the development of modern technology. 19th century, AC transmission system has appeared, but he still insists on DC transmission, and with G.
Westinghouse Niehaus Company lost the contract of Niagara Hydropower Project in fierce competition;
He blindly tested the magnetic grinding equipment in the laboratory, and the funds for inventing electricity dried up and had to give up. However, Edison's contribution to the development of electricity and the application of electrical appliances has promoted him to become one of the greatest inventors in human history.

The deeds of lei feng
Lei Feng is a model soldier,1February 8, he was born in a poor peasant family in a small mountain village in Hunan Province. He didn't go to school until 1950. 18 years old, working as a steel worker. He is often praised for his excellent work. 1960 1 joined the army on August 8.
