(Nikola Tesla, 1856-1943, born July 10, 1856) is a world-renowned inventor, physicist, mechanical engineer and electrical engineer. Of Serbian descent, he was born in Croatia (later incorporated into the Austrian Empire). Tesla is considered an important inventor in history. He is also known for his contributions to electricity and magnetism in the late 19th and early 20th centuries. His patents and theoretical work on modern alternating current electrical (AC) systems, including polyphase power distribution systems and AC motors, helped usher in the Second Industrial Revolution. In the United States, Tesla's reputation in history or popular culture rivals that of any other inventor or scientist. After he demonstrated wireless communication in 1893 and became the winner of the Battle of the Electric Currents, he became highly respected as one of America's greatest electrical engineers. Many of his early results became precursors to modern electrical engineering, and many of his discoveries were of groundbreaking importance. In 1943, the U.S. Supreme Court recognized him as the inventor of radio. Tesla never cared about his financial situation and died poor and forgotten at the age of 86. Tesla’s legacy can be seen everywhere in the modern world of electricity. In addition to his achievements in electromagnetics and engineering, Tesla is also considered to have contributed to various fields such as robotics, ballistics, information science, nuclear physics, and theoretical physics. In his later years, Tesla was regarded as a mad scientist and was noted for his claims to create bizarre scientific inventions. [1][2] Many of his achievements have been used with some controversy to support many pseudosciences, such as UFO theory and New Age occult theory. Tesla's contemporary admirers regard him as "the man who created the twentieth century. He is 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. If Tesla would have been the richest man in the world if he had not been forced to give up the patent rights of alternating current for free use by the world ($2.53 per horsepower). His dream was to provide the world with inexhaustible energy. His life was miserable. , I sympathize with him very much, but he is a peerless genius. It is a pity that not many people remember him. He was born in Smilyan, Croatia, Yugoslavia on July 10, 1856. His father was a priest and his mother was the inventor of the eggbeater. He made countless inventions throughout his life. In 1882, he invented alternating current (AC) shortly after Edison invented direct current (DC), and created the world's first alternator and created polyphase power transmission technology in 1895. In 1897, he manufactured generator sets for the Nicaragua Power Station in the United States, which is still one of the world's famous hydropower stations. In 1897, he made Marconi's radio communication theory a reality. In 1898, he created the world's first hydropower station. A radio-controlled boat and patented radio-controlled technology (U.S. Patent No. 613.809). In 1899, he invented X-ray photography technology. Other inventions include: radio, radar, fax machine, vacuum tube, neon tube, Missile navigation, planetary defense system, etc. Even the magnetic density unit named after him (1 Tesla = 10,000 Gause) shows his contribution to magnetism. When he was young, Tesla was very smart and could do it quickly in his mind. For complex calculations, the teacher always thinks he is cheating. In addition to Croatian, Tesla can also speak 7 languages: Czech, English, French, German, Hungarian, Italian, and Latin. In middle age, Tesla became a close friend with Mark Twain, and they spent a lot of time in the laboratory and other places. Tesla never married because he could not handle intimate relationships. At the age of 40, he said: "A certain Frenchman." Actresses kept coming to me and I could hardly concentrate. It's such a shame, sometimes I feel so lonely.
"(A certain french actress kept comming to me and made impossible for me to concentrate. It's pity too. For sometimes, I feel so lonely.) Although he devoted his life to continuous research and obtained about 1,000 patented inventions, his life's Research was not for self-interest. Much of Tesla's most prolific creative period was spent in the United States, for example: the radiation energy receiver, which was about the conversion of cosmic ray energy. We know nothing about its working principle. Unfortunately, his contemporaries took advantage of the love and talent of this talented scientist, defrauding him of his research results and honors, and became rich because of his invention. Tesla was in poverty and suffered from financial difficulties for many years. Sometime between the evening of January 5 and the morning of January 8, 1943, Tesla died of heart failure alone in a New York hotel at the age of 86. Tesla was already heavily in debt when he died. Why was such an extraordinary scientist forgotten by history? Because although his alternative inventions made great contributions to mankind, they also caused many profitable companies to collapse in an instant. Those who suppressed him include Thomas Edison, J. Pierpont Morgan, who supported him and then abandoned him, etc. After his death, the US government secretly deleted historical records and reports about him, and most of his research results were confiscated and juxtaposed. It was classified as a high-level secret, so his name was erased.
