What did nikola tesla invent?

Nikola tesla \x0d\ (nikola tesla, 1856- 1943, born in July 1856) is a world-famous inventor, physicist, mechanical engineer and electrical engineer. He was born in Croatia (later incorporated into the Austrian Empire) and is of Serbian descent. Tesla is considered as an important inventor in history. His contributions to electricity and magnetism at the end of 19 and the beginning of the 20th century are also well known. His patents and theoretical work forms are based on modern AC systems, including multiphase distribution systems and AC motors, which helped him bring about the second industrial revolution. \x0d\ In the United States, Tesla's reputation in history or popular culture can rival that of any other inventor or scientist. After he demonstrated wireless communication in 1893 and became the winner of the current war, he became one of the greatest electronic engineers in the United States and was highly respected. Many of his early achievements became pioneers of modern electronic engineering, and many of his discoveries were groundbreaking and important. 1943, the US Supreme Court recognized him as the inventor of radio. Tesla never cared about his financial situation. At the age of 86, he was poor and forgotten. \x0d\ In the modern world where electricity is used, Tesla's legacy can be seen everywhere. In addition to its achievements in electromagnetism and engineering, Tesla is also considered to have made contributions in robotics, ballistics, information science, nuclear physics and theoretical physics. Tesla was regarded as a mad scientist in his later years, and attracted attention because he claimed that he could create weird scientific inventions. [1][2] Many of his achievements have been applied to support many pseudosciences with some controversies, such as UFO theory and mysterious theory in the new century. Tesla's contemporary admirers regard him as "a man who created the twentieth century and was a great man forgotten by the world". He invented the alternator, and Edison loved the DC generator he invented and tried his best to suppress Tesla. Tesla would be the richest man in the world if it hadn't been forced to give up the patent for free use of alternating current ($2.53 per horsepower). His dream is to provide inexhaustible energy for the world. He lives a miserable life and sympathizes with him very much, but he is an unparalleled genius. Unfortunately, not many people remember him. \ x0d \1July, 856 10 was born in milian, Yugoslavia. His father is a priest and his mother is the inventor of the eggbeater. There are countless inventions in his life. 1882, shortly after Edison invented direct current (DC), he invented alternating current (AC), made the world's first alternator, and founded multiphase transmission technology. 1895, he made generator sets for Nicaragua Power Station in the United States, making the power station still one of the world-famous hydropower stations. 1897, he made Marconi's radio communication theory come true. 1898, he built the world's first radio-controlled ship, and applied for a patent for radio control technology (U.S. PatentNo. #6 13.809). 1899, he invented the X-ray photography technology. Other inventions include: radio, radar, fax machine, vacuum tube, neon tube, missile navigation, interstellar defense system and so on. Even the magnetic density unit named after him (1 Tesla = 10000 gauss) shows his contribution to magnetism. When she was young, Tesla was very clever. She could quickly complete complex calculations in her \x0d\. The teacher always thought she was cheating. \x0d\ Tesla can speak many languages fluently. Besides Croatian, he can speak seven languages: Czech, English, French, German, Hungarian, Italian and Latin. In middle age, Tesla and Mark Twain became close friends, and they spent a lot of time in the laboratory and other places. \x0d\ Tesla never got married because she couldn't handle intimate relationships. The 40-year-old said: "I can hardly concentrate because a French actress keeps coming to me." What a pity. Sometimes I feel lonely. " A French gesture tried to get close to me and made me unable to concentrate. This is pitytoo. Sometimes I feel lonely. ) \ x0d \ Although he devoted himself to continuous research all his life and obtained about 1000 patent inventions, his lifelong research was not for his own benefit. Unfortunately, his contemporary entrepreneurs took advantage of the genius scientist's love and talent, defrauded his research achievements and honors, and became rich because of his inventions. But Tesla is poor and has been in financial trouble for many years. 194365438+1sometime between the evening of October 5th and the morning of October 8th, Tesla died of heart failure alone in new york Hotel at the age of 86. Tesla was heavily in debt when he died because he refused to sell his patent for alternating current. \x0d\ Why are such extraordinary scientists forgotten by history? No one ever said that? Although his alternative inventions have made great contributions to mankind, at the same time, he wants to prompt many profitable enterprises to close down instantly. His oppressors included Thomas Edison, and J pierpont Morgan supported him and abandoned him. After his death, the American government artificially and secretly deleted his historical records and reports, and most of his research results were confiscated and classified as top secret, so his name was erased.
