Nikola tesla was born in 1856 into a Serbian family. He studied electrical engineering at Graz University of Technology in Austria on 1875. He dropped out of school after only one semester. After dropping out of school, he cut off contact with his family and traveled alone.
1884, Tesla came to New York, USA, and worked in Edison's company as a general engineer responsible for maintaining DC generators. Although Edison was a great inventor, he was also a very stingy, stingy and jealous capitalist and businessman. Tesla didn't get the reward and respect he deserved, so he started his own business.
In the first two years after leaving Edison, Tesla's life was very embarrassing, and then gold was bound to shine. 1888, Tesla obtained two patents on alternator, invented alternator, and launched a "current war" with Edison. At that time, Edison's direct current dominated the American power industry. Direct current has a fatal defect: electric energy will be consumed when it is transmitted through cable, so the cost of long-distance transmission of direct current is quite high, while alternating current is more efficient. In order to suppress Tesla, Edison tried his best to destroy and vilify the alternating current, which was very dangerous, and even sent someone to burn down Tesla's laboratory, but Tesla still won the final victory of the "current war".
Tesla is an unparalleled genius. He was 1 1 times selected as the winner of the Nobel Prize in Physics, including two with Edison, but Tesla refused all of them and quipped: "How can you enjoy a wife with others?" Especially how to enjoy being with a liar? "He didn't win a Nobel Prize, but he was respected by many Nobel Prize winners in physics, because as long as scientists study his works, the proportion of being inspired to win the Nobel Prize in physics reaches 27%!
Tesla had 700 patents in his life and could have become the richest man in the world, but unlike Edison, he didn't take money seriously. Originally, the patent fee for alternating current was 2.53 dollars per horsepower, and it could become the richest man in the world within one year, but Tesla tore up the patent of alternating current and let human beings use it for free. As for the patent fees of other inventions he earned, only the basic expenses are left, and all the rest are donated.
1943, nikola tesla, who never married, died in a hotel at the age of 86. He is called "the man who created the twentieth century" and has made greater contributions than Edison!
