What did Edison invent
¡øThomas AlvaEdison (1847-1931) Thomas AlvaEdison (Thomas AlvaEdison) is a world-famous American electrician and inventor, in addition to his inventions and contributions in the phonograph, electric light, telephone, telegraph, film, etc., he also has many famous creations and insights in the fields of mining, construction, chemical industry, etc. Edison had about 2,000 inventions in his lifetime, and made great contributions to human civilization and progress.
In the history of science in the world, there is such a great scientist: he not only devoted all his life's energy to the cause of science, but also left a will after his death, donating all his legacy to the cause of science, so as to reward future generations and strive to climb the peak of science. Today, the science prize named after him has become the highest scientific award that has attracted worldwide attention. His name, together with the achievements made by mankind in scientific exploration, has forever remained in the annals of civilization in the development of human society.
Bovine insulin (synthesized in the laboratory, not naturally existent, and greatly helped in the later treatment of diabetes) SARS vaccine (after all, we are the hardest-hit country) AIDS vaccine (China is the first to research "successful" (phased victory, still in the deepening of research) and put into production, but it has not yet been mass-produced) water-soluble paint technology (it seems that a farmer feels that he has to use oil to make trouble when he paints his house, so he buried himself in studying at home for many years, prepared such a recipe for mixing paint with water, and then sold it
Edison, the great inventor, invented many things in his life, however, the only thing that could get people's warm welcome immediately was the electric lamp, because the benefits of the electric light are visible and touchable, and its appearance means that people have another round of sun, and people's activities are no longer restricted by the night objects. As early as 1821, British scientists David and Faraday invented a kind of electric lamp called the arc lamp. This kind of electric lamp uses a charcoal rod as a filament. Although it can emit bright light, the light is dazzling and consumed
No, Edison had more than 1,000 inventions in his lifetime, and 1,328 were authorized by the patent office. There is also a great inventor in the world, Nikola Tesla, who also has more than 1,000 inventions in his lifetime.
Chronology of Edison's Inventions: On October 11, 1868, he invented the "voting counter" and obtained the first patent in his life. In October 1869, he co-founded the "Popper-Edison Company" with a friend. In 1870, he invented the universal printing press, granted a patent, and received $40,000. From 1872 to 1876, he invented the electromechanical telegraph, the automatic repetition telegraph method, the double and quadruple telegraph method, and the manufacture of wax paper carbon resistors. Issued in 1875
There are 1,328 kinds of inventions registered by the bureau (the most of them is in 1882, 141 patents have been obtained, and there is an invention every three days on average).
Important invention of the photocopier At first, Edison's invention of paraffin paper was only widely used in food, candy packaging materials, and later he tried to carve out the outline of the text on the wax paper, forming a paraffin lettering paper plate, under the paper board on the white paper, and then use the ink roller to roll from the engraved paraffin paper, a wonderful thing happened, clear handwriting appeared on the white paper

Set up his own manufacturing factory in New York.1872-1876 Invented the electromechanical telegraph, automatic repetition telegraph method, double and quadruple telegraph method, and manufactured wax paper carbon resistors.1875 Invented acoustic wave analysis
Synchronous transmitter The early telegraph can only transmit one message at a time, and can not exchange signals at the same time, because Edison himself is a telegraph technician, he set out to improve the traditional telegraph, to create a double transmitter, and in 1874 developed a quadruple telegraph, that is, the synchronous transmitter

It was Bell who invented the telephone, and Edison reformed and perfected the telephone! Bell and his assistant Hua Shengsheng designed a microphone with a magnetic reed in the center. This kind of microphone can transmit sounds of various frequencies, and the vibrating reed is converted into various electrical oscillations through electromagnetic induction. The device of the same structure is placed at the other end of a certain distance as a receiver. On February 14, 1876, this invention was granted a patent registration. After Bell invented the telephone, the great inventors Edison and Hughes and so on.
