Nikola Tesla. (Nikola Tesla, 1856-1943, born July 10, 1856) is one of the world's greatest inventors, physicists, mechanical engineers and electrical engineers. 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 the patent on alternating current for free use by the world ($2.53 per horsepower), he would be 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. Genius comes from diligence, and in order to devote himself to scientific research, Tesla never married. He said: "Electricity has injected the most precious things into my tired and weak body - the vitality of life and spiritual vitality." In order to turn his ideas into practical inventions, he was reluctant to sleep and only slept for more than 2 hours a day. In the end, he obtained more than 1,000 invention patents alone.
There is a saying: "Genius is hard-working and hard-working, and there is no need to whip up a whip; work hard all your life to act in a big show, and create amazing achievements in the world." Tesla's patent was conceived and written by him alone, and he is a veritable patent inventor. ; And Edison's patent was completed by the huge experimental team of the General Electric Company he founded. Edison owned the patent because he was the boss of General Electric Company. Edison was not the real inventor of the patent; Tesla graduated from the University of Prague , Edison did not graduate from elementary school. Therefore, in a one-to-one comparison, the lone ranger Tesla's personal scientific and inventive achievements are many times greater than the purely commercial invention achievements of Edison, who completely relied on the commercial R&D team. Although he devoted his life to continuous research and obtained about 1,000 patented inventions, his lifelong research was not for his own benefit. Tesla's most prolific creative years were spent in the United States. Many of them remain unrepeatable to this day. For example: radiated energy receiver. We know nothing about how it works except that it is a converter of cosmic ray energy. Unfortunately, entrepreneurs of his generation took advantage of the love and talent of this talented scientist, defrauded him of his research results and honors, and became rich because of his inventions. But Tesla is impoverished and has been experiencing financial constraints for many years. Sometime between the evening of January 5 and the morning of January 8, 1943, Tesla died alone of heart failure in a New York hotel at the age of 86. Tesla was deeply in debt when he died because he refused to sell his alternating current patent. Why has such an extraordinary scientist been forgotten by history? No one has ever praised it? Because although his alternative inventions made great contributions to mankind, they also caused many profitable companies to close down instantly. Among those who suppressed him were Edison and J. Pierpont Morgan (John Pierpont) who supported and then abandoned him. Morgan), etc. After his death, the US government secretly deleted historical records and reports about him. Most of his research results were confiscated and classified as high-level secrets, so his name was erased. Tesla’s death ray and the heresy in the era of electrical devices that transmit 100 million volts over infinite distances: the invention of alternating current. In 1888, many newspapers at that time reported that the famous inventor Thomas Edison claimed that 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, today everyone knows how much the world needs alternating current. The invention of alternating current improved people's lives, enhanced industrial development and accelerated scientific progress. But why did Edison repeatedly attack alternating current and its inventor, Tesla? 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, DC power is not conducive to long-distance transmission, and power stations need to be added every 1 kilometer, but AC power can be transformed by transformers for long-distance transmission. Using DC power is more expensive, and its efficiency is far less than that of AC power. Based on conflicts of interest, Edison tried his best to suppress Tesla's invention. Prior to this, Tesla invented 24 new designs for the great scientist Edison, including the design of DC generators, which were 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. Niagara Hydropower Station that marks the centenary mark. If you have ever been to Niagara Falls in the United States, I believe you will all be in awe of this magnificent spectacle. Tens of thousands of tons of river water converged from all directions, pouring down with the force of landslides and ground cracks. The rumbling sound of the sudden impact of the river water was terrifying. This ever-flowing river contains unexpectedly rich resources. In 1897, the world-famous Niagara Hydropower Station, the first 100,000-horsepower power station was built, becoming the main source of power supply for The City of Buffalo, New York State, 35 kilometers away. Since then, more than a dozen large and small power stations have been built one after another, and the electricity produced every day is enough to supply a quarter of the total demand of New York State in the United States and Ontario, Canada. To this day, this power construction, which was built over 100 years ago, is still operating as usual and has never stopped producing natural energy. It can be said to be a miracle in the scientific history of mankind in the past century. This century-old miracle in science is a design created by the genius scientist Tesla in his thirties, which exclusively used 9 of his patented inventions, including the alternating current generator and alternating current transmission invented by Tesla. technology. In fact, at that time, industrial and commercial, public facilities and household appliances all used expensive direct current. Because of the losses in the circuit, when using direct current, a generator set must be built every one kilometer. Therefore, when building the Niagara Hydropower Station, it was impossible to transmit the power in the form of direct current to Buffalo, New York, 35 kilometers away. Therefore, when building the Niagara Hydropower Station, the Americans adopted the AC power supply and transmission technology invented by Tesla, and used high-voltage power to achieve long-distance power supply. This epoch-making invention not only solves the problem of long-distance power supply from the Niagara Hydropower Station, but also brings people a convenient and cheap electricity consumption environment. Later, a bronze statue of Tesla was erected in Niagara Falls Park to commemorate his contribution to the Niagara Hydropower Station. Selfless Contribution: Exemption from Patent Royalties on Alternating Current Tesla’s lifetime of inventions bear witness to his selfless contributions to society. Although he devoted his life to continuous research and obtained about 1,000 patented inventions. But he was in poverty in his later years and suffered from financial constraints for many years. Although many entrepreneurs took advantage of this genius scientist's love and talent and defrauded him of his research results and honors, in his later years he still worked hard to research and invent for the happiness of mankind. Among Tesla's many inventions, the ones that benefited the public the most are alternating current (AC) and AC generators. In every corner of the world, the development of economy and trade, scientific progress and enjoyment of life are inseparable from the help of alternating current. The blackouts in the United States and Europe at the end of 2003 brought social and economic paralysis. As early as 1882, Tesla had invented the world's first alternating current generator, and in 1885 he invented multi-phase current and multi-phase power transmission technology, which is now a 50-60 Hz (hertz) method of power transmission that is widely used around the world. . In a meeting of the U.S. Congress on July 10, 1990, more than 10 U.S. senators commemorated Tesla's 134th birthday, praised his contribution to electricity science, promoted how he changed mankind's understanding of the concept of power generation, and praised Tesla. He was hailed as a greater inventor than Edison. After Edison invented direct current, electrical appliances were widely used, but the cost of electricity was very high. Therefore, operating and exporting direct current became the most profitable business at that time.
By 1884, after Tesla left the Edison Company, he met George Westinghouse, the head of the Westinghouse Company, and with his support, he officially brought alternating current to the society of the day in 1888. At the opening of the World's Fair in Chicago in January 1893, Tesla shocked the crowd by demonstrating that alternating current could power 90,000 light bulbs simultaneously, as direct current simply could not achieve this effect. Afterwards, Tesla obtained the right to undertake the electrical design of the Niagara Hydropower Station based on this demonstration. Since then, alternating current has made a comeback, replacing direct current as the mainstream power supply. Tesla owned the patent for alternating current. At that time, Tesla had to pay a royalty of US$1 for each AC produced. Driven by strong interests, a consortium at that time threatened Tesla to give up this patent and intended to monopolize and profit. After many negotiations, Tesla decided to give up the alternating current patent, on the condition that the alternating current patent would be permanently public. From then on, he tore up the patent for alternating current and lost the right to collect royalties. From then on, alternating current was no longer patented and became a free invention.
