1July 856 10 Tesla was born in Smilian, Austria. His father is a priest, and he wanted Tesla to inherit his father's career since he was a child. But Tesla was determined to be an engineer since he was a child and went to school in Karlovac, Croatia when he was young.
1875, Tesla was admitted to Graz University of Technology with excellent results, and studied in Physics Department, Mathematics Department and department of mechanical engineering successively. However, due to his poor family background, he was revoked his scholarship by the Military Border Defense Bureau after only one year of college education, and was forced to drop out of school because he could not afford the tuition. After dropping out of school, he didn't neglect his studies, but went to college every day. But who would have thought that such auditors would play an important role in the future process of human industrial civilization?
1884 Tesla was recommended by Charles Bachero to work in Edison's laboratory. His letter of recommendation was written by Charles Bachero to Edison. There is a sentence: "I know there are two great people, one is you and the other is this young man".
Later, Edison arranged for him to work in a machinery company. At first Edison only arranged for Tesla to do some simple electrical design, but because of Tesla's strong learning ability, Edison paid attention to it. Edison gave Tesla full trust and put him in charge of the design of DC cars.
Edison promised to reward Tesla with $50,000 as long as he could design a DC motor, but when Tesla designed a DC motor, Edison refused to give the $50,000 reward, thinking that he was joking and only symbolically raised his salary. Moreover, during the company, Edison was very stingy with Tesla, and gradually, the two people who had trusted him gradually alienated.
Tesla resigned from Edison's company and set up his own company at 1886. With the invention of the power system rectifier of the first generator, Tesla obtained his first patent.
When Tesla studied the DC project in Edison Company, he realized that the commercialization of DC would pay a huge price, so he began to study alternating current, because alternating current can effectively reduce energy consumption during long-distance transmission. Edison found that Tesla's alternating current threatened his monopoly position in DC and began to suppress it crazily.
In order to make the world hate alternating current, Edison did an experiment of alternating current electric shock on condemned prisoners. When the condemned man was electrocuted by alternating current, everyone present was shocked, and these cruel pictures were also reported by the media.
Therefore, in people's minds, alternating current is synonymous with "death", and Tesla has been hit hard because of the misunderstanding of the masses, but even this has not stopped Trass's creativity. He improved the alternating current and studied wireless transmission and wireless call.
Until 1893, Westinghouse and Edison competed for the lighting project of Columbia Expo. The current "DC and AC" battle was finally won by Westinghouse and Trass' "AC" and won the lighting project of the Expo.
Trass wants to show the American people the reliability and development of alternating current. Through this project, "alternating current" has been recognized by people. At that time, Tesla held the patent right of alternating current, and for every horsepower of alternating current sold, Tesla could get a patent fee of $2.50. At this rate, he will soon become the richest man in the world. I didn't expect that he chose to give up the patent right to make the patent of alternating current permanent and give it to all mankind for free!
1935, Tesla dug a deep well in the laboratory and placed a steel casing in the well. After blocking the hole, he input vibrations of different frequencies into the well. In this process, Tesla found that once the frequency reaches a certain index, the ground will vibrate strongly and the surrounding houses will collapse.
So much so that The New York Times exaggerated at that time: Tesla himself induced an earthquake that almost razed new york to the ground. Tesla also joked: I can split the earth in half within a year if I want! In order to develop more inventions that can change the world, he chose not to marry for life and stayed in the laboratory most of the time.
Sadly, although Tesla has obtained more than 700 invention patents, he did not ask for a penny for these patents, so that Tesla could not even pay the rent in his later years. He is not good at cheating and likes to fight alone. For him, a laboratory where he can do any research is the biggest dream.
When a reporter interviewed him, he asked such a question: You could have become the richest man in the world, but you chose not to take a penny. Do you think your efforts are worth it? Tesla replied: the value of a person should not be seen by what he has achieved, but by what he has contributed to mankind. 1943 65438+ 10, Tesla, who was called "the Grinch of Science" by the people, died of heart failure in a small hotel at the age of 86.
