Nikola Tesla (1856-1943, born July 10, 1856) is one of the world's greatest inventors, physicists, mechanical engineers and electrical engineers. one. 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'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. 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 hadn't been forced to give up his patent on alternating current for free use by the world ($2.53 per horsepower), he would have been the richest man in the world. His dream is to provide the world with inexhaustible energy. Tesla never cared about his financial situation and died poor and forgotten at the age of 86. Although he was a genius, it is a pity that not many people remember him. He was born in Smiljan, Croatia, Yugoslavia on July 10, 1856. His father was a priest and his mother was the inventor of the egg beater. He made countless inventions throughout his life. In 1882, shortly after Edison invented direct current (DC), he invented alternating current (AC), built the world's first alternator, and created polyphase power transmission technology. In 1895, he manufactured generator sets for the Niagara Power Station in the United States, which is still one of the world's famous hydropower stations. In 1897, he made Marconi's theory of radio communication a reality. In 1898, he built the world's first radio-controlled boat and patented radio-controlled technology (U.S. Patent No. #613.809). In 1899, he invented X-ray (X-Ray) photography technology. Other inventions include: radio, radar, fax machine, vacuum tube, neon light tube, missile navigation, planetary defense system, etc. Even the magnetic density unit named after him (1 Tesla = 10,000 Gause) further demonstrates his contribution to magnetism. When he was young, Tesla was very smart and could complete complex calculations quickly in his mind. His teachers always thought he was cheating. Tesla can speak multiple languages ??fluently. In addition to Croatian, he speaks 7 languages: Czech, English, French, German, Hungarian, Italian, Latin. In middle age, Tesla and Mark Twain became close friends, 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 French actress keeps coming to see me, and I can hardly concentrate. It's a pity, sometimes I feel very 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. After selling his alternating current patent, Tesla was already deeply in debt. Why was such an extraordinary scientist forgotten by history? Because although his alternative inventions made great contributions to mankind, they also inspired many people. The profitable business collapsed instantly. Among those who suppressed him were Edison and J. Pierpont Morgan, who supported and then abandoned him. After his death, the U.S. government secretly deleted historical records and reports about him. His research results were greatly Some of them were confiscated and classified as high-level secrets, so his name was erased. The heresy of the era: the invention of alternating current. In 1888, many newspapers at the time reported that the famous inventor Thomas Edison claimed that Nikola Tesla. (Nikola Tesla) is a major "heretic" in the scientific community. The alternating current (AC) he invented directly affects human life safety, and he has repeatedly demonstrated how dogs and cats die instantly after passing through AC (the "electric chair" death penalty was also inspired) . But in fact, everyone knows today how much the world needs the existence of alternating current. The invention of alternating current has improved people's lives, enhanced the development of industry, and promoted scientific progress. But why did Edison attack alternating current and it again and again? What about Tesla, the inventor? The answer is that the emergence of alternating current directly threatened Edison's direct current business, because there are too many shortcomings and limitations in using direct current. For example, direct current is not suitable for long-distance transmission. Adding power stations, but alternating current can be transformed by transformers for long-distance transmission; using direct current is more expensive and far less efficient than alternating current. Based on conflicts of interest, Edison tried his best to suppress Tesla's invention before this. He invented 24 new designs for the great scientist Edison, including the design of the direct current generator, which was patented by Edison and mass-produced. But the reward for his efforts was a ruthless scam and ridicule. As a result, Tesla became angry and broke away from Edison and his company. This was the prelude to the historic War of Currents. In 1888, Tesla received support from Westing House entrepreneur Geovge Westing House to develop an alternating current system that had been conceived for 6 years. Half a year later, the alternating current generator he developed was patented, and he was invited by the American Institute of Electrical Engineers to explain and demonstrate the research results of the alternating current system. Because the efficiency of alternating current is far superior to that of direct current, alternating current began to be widely used and gradually replaced the traditional direct current. Driven by profit, Edison vigorously criticized Tesla and branded him a "scientific heretic", and a scientific persecution began.
Although alternating current has become the mainstream of industrial and social power supply today and has become a necessity in our daily lives, the name of Nikola Tesla has always been forgotten, and has not even received due justice. This is the masterpiece of "orthodox" science.
