Tesla only slept for 2 hours every day, and finally obtained more than 700 invention patents on his own. I will never get married in order to devote myself to scientific research. Besides being a scientist, he is also a poet, philosopher, music connoisseur and linguist. He is proficient in eight languages: Serbian, English, Czech, German, French, Hungarian, Italian and Latin. Tesla's life-long invention witnessed his selfless contribution to society. Although he devoted his life to continuous research, he obtained about 1000 patent inventions. However, in his later years, he was down and out for many years. Although many entrepreneurs took advantage of this talented scientist's love and talent and defrauded him of his research achievements and honors, he still worked hard to research and invent for the happiness of mankind in his later years.
Among Tesla's many inventions, its various AC motors are the most beneficial to the public. In every corner of the world, the development of economy and trade, the progress of science and the enjoyment of life are inseparable from the help of alternating current. At the end of 2003, there was a blackout in the United States and a blackout in Europe, which once plunged into social and economic paralysis. As early as 1882, Tesla had invented the world's first high-frequency AC motor, and in 1885, it invented multiphase current and multiphase electricity technology.
After Edison invented direct current, electrical appliances were widely used, and the electricity bill was also high, so exporting direct current became the most profitable business at that time. 1885, Tesla left Edison Company and met George Westinghouse, the head of Westinghouse Company. With his support, Tesla officially brought alternating current to the society at that time in 1888. 1At the Columbia Expo in May, 893, Tesla demonstrated AC lighting and became the winner of the "current war". After that, Tesla won the right to undertake the power design of Niagara Hydropower Station.
Since then, alternating current has replaced direct current as the mainstream of power supply. Tesla, on the other hand, has the patent right of alternating current. At that time, it had to pay Tesla a patent fee of $2.50 for every horsepower of alternating current sold. Driven by strong interests, a consortium threatened Tesla to give up this patent right with the intention of monopolizing profits. After many negotiations, Tesla decided to give up the patent of alternating current, provided that the patent of alternating current was made public permanently. Since then, he tore off the patent of alternating current and lost the right to collect patent fees. Since then, alternating current has not been patented and has become a free invention. If the invention patent of alternating current is not given to all mankind for free use, and alternating current brings him a "patent fee" of 2.5 dollars per horsepower, he will be the richest man in the world.
Up to now, Serbian banknotes are still printed with nikola tesla's head. Some people think that such an advanced and prolific genius inventor and scientist has been forgotten by the world, which is due to the cooperation between Tesla and Edison and his different style of doing things. Edison is good at business operation and has a business mind, while Tesla is only immersed in inventions and never considers making a fortune with his own patents. While working for Edison, Edison promised to pay him $50,000 after Tesla helped him improve the generator. However, Edison deceived Tesla, which led Tesla to resign angrily. Others thought that Tesla's invention was too advanced to be accepted at that time. He and his achievements have become the object of debate in the scientific community, and some even call his achievements "pseudoscience". Some people also lamented that Tesla was born at an untimely time, and the aura of "great inventor" Edison covered up the "controversial" Tesla. After Tesla died, most of the information and data about him were lost. Even in the 6.5438+0.5 million exhibits collected by Nikolai Tesla Museum in Belgrade, there are few scientific research data about Tesla.
1960 At the international metrology conference held in Paris, the unit of magnetic induction intensity was named Tesla to commemorate this Serbian-American inventor and electrical engineer who made important contributions in the field of electromagnetism.
Nikola tesla 1943 65438+ 10 died of heart failure in Room 3327 of new york Hotel on October 7th. Tesla was very poor because he refused to sell his patent for alternating current and left a large debt after his death. Later that year, the US High Court decided to maintain Tesla's patent number.
Although he is an American, after Tesla's death was made public, the foreign property depository still sealed his research materials. Tesla continued his research on death ray weapons before his death. The US government has not found a safe prototype device (in fact, Tesla has no research results). His research was declared top secret.
Because of the potential importance of his research, Tesla's family and the Yugoslav embassy have been trying to retrieve these items from the American authorities. Finally, his nephew Sava Kosanovic took ownership of some of his personal belongings.
Tesla's funeral was held on June1943+1October 12 at St. John's Cathedral in Manhattan, new york. His ashes were buried in Nikola Tesla Museum in Belgrade, Serbia on 1957.
