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 America and was highly respected. Many of his early achievements became pioneers of modern electronic engineering, and many of his discoveries were groundbreaking and important. In 1943, the United States Supreme Court recognized him as the inventor of radio.
Tesla's legacy can be seen everywhere in the modern world where electricity is used. Apart from his achievements in electromagnetism and engineering, Tesla is also considered to have contributed to various fields such as robotics, ballistics, information science, nuclear physics and theoretical physics. Tesla was regarded as a mad scientist in his later years and was noticed for claiming that he could create weird scientific inventions. Many of his achievements have been applied with some controversies to support many pseudosciences, such as UFO theory and mysterious theory in the new century. Contemporary admirers of Tesla 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. Tesla would be the richest man in the world if he hadn't been forced to give up the patent of alternating current for free use ($2.53 per horsepower). His dream is to provide the world with inexhaustible energy. Tesla never cared about his financial situation and died in poverty and forgetfulness at the age of 86. Although he is a peerless genius, it is a pity that not many people remember him.
On July 1th, 1856, he was born in Smiliang, Croatia, Yugoslavia. His father was a priest and his mother was the inventor of the eggbeater. There are countless inventions in his life. In 1882, shortly after Edison invented direct current (DC), he invented alternating current (AC), made the world's first alternator, and founded multiphase power transmission technology. In 1895, he made generator sets for Niagara Power Station in the United States, making the power station still one of the world-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 ship, and patented the radio-controlled technology (U.S. PatentNo. #613.89). In 1899, he invented X-Ray photography. Other inventions include: radio, radar, fax machine, vacuum tube, neon tube, missile navigation, star defense system, etc. Even the unit of magnetic density named after him (1 Tesla = 1, Gause) shows his contribution to magnetism.
When he was young, Tesla was very clever, and he could finish complex calculations in his head quickly. The teacher always thought he was cheating.
Tesla can speak many languages fluently. Besides Croatian, he can speak seven languages: Czech, English, French, German, Hungarian, Italian and Latin.
Tesla and Mark Twain became close friends in middle age, and they spent a lot of time in the laboratory and other places.
Tesla never married because she couldn't handle intimacy. At the age of 4, he said, "A French actress kept coming to me, which made me almost unable to concentrate. It's a pity. Sometimes I feel very lonely. " (a certain French action belief coming to me and made impossible for me to concentrate. it's pitytoo. for some times, I feel so lonely.)
Although he devoted his life to continuous research and obtained about 1, patented inventions, his life-long research was not for his own benefit. Tesla's most productive creative period was spent in the United States. A large part of them cannot be repeated until today. Such as a radiant energy receiver. We know nothing about its working principle except that it is a converter about cosmic ray energy. Unfortunately, his contemporary entrepreneurs took advantage of the genius scientist's love and talent, cheated his research achievements and honors, and became rich because of his inventions. But Tesla is down and out and has been financially strapped for years. Sometime between the evening of January 5th and the morning of January 8th, 1943, Tesla died of heart failure alone in new york Hotel at the age of 86. Tesla was in debt when he died because he refused to sell his patent for alternating current.
why are such extraordinary scientists forgotten by history? No one has ever told it? Because his unique inventions have made great contributions to mankind, but at the same time, they have prompted many profitable enterprises to close down instantly. Some people suppressed him, such as Edison, J. Pierpont Morgan (John Pierpont Morgan), who supported him and abandoned him. After his death, the American government secretly deleted his historical records and reports, and most of his research results were confiscated and included in top secrets, so his name was erased.
heresy in the era: the invention of alternating current: the invention of alternating current
In 1888, many newspapers reported that the famous inventor Thomas Edison declared that Nikola Tesla was a "heresy" in the scientific community, and his invention of alternating current (AC) directly affected human life safety, and repeatedly showed how dogs and cats died instantly after passing AC ("electric chair").
but in fact, everyone knows today how much the world needs alternating current. The invention of alternating current has improved people's life, promoted the development of industry and promoted the progress of science. But why did Edison attack alternating current and its inventor, Tesla, again and again? The answer is that the emergence of alternating current directly threatens Edison's direct current business. Because there are too many disadvantages and limitations in using DC. For example, direct current is unfavorable for long-distance transmission, and power stations should be added every 1 km, but alternating current can be transformed by transformers as long-distance transmission; The use of direct current is more expensive and its efficiency is far less than that of alternating current. Based on the conflict of interests, Edison tried his best to suppress Tesla's invention.
before that, Tesla invented 24 new designs for the great scientist Edison, including the design of DC generator, which was patented by Edison and mass-produced. However, the reward for his hard work was a ruthless scam and ridicule. As a result, Tesla became angry and left Edison and his company. This is the prelude to the current war in history.
in 1888, Tesla was supported by Geovge Westing House, an entrepreneur of Westinghouse, to develop an alternating current system that had been conceived for six years. Half a year later, the AC 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 AC system. Because the efficiency of alternating current is far superior to that of direct current, alternating current is widely used and gradually takes the place of traditional direct current. Driven by interests, Edison vigorously attacked Tesla and branded it as a "scientific heresy", and a scientific persecution came into being. Although alternating current has become the mainstream of industrial and social power supply and the necessity of our daily life, the name of Nikola Tesla has been forgotten and even has not been rehabilitated. This is the masterpiece of orthodox science.
the century-old Niagara Hydropower Station
If you have been to Niagara Falls in the United States, I believe everyone will give a heartfelt admiration for this magnificent spectacle. Tens of thousands of tons of river water converge from all directions and pour down with the trend of landslides. The rumbling sound of the sudden impact of the river water is daunting. In this endless river, there are unexpected rich resources.
in 1897, the first 1,-horsepower power station in the world-famous Niagara Hydropower Station was built, which became the main power supply source in The City of Buffalo, New York, 35 kilometers away. Since then, more than a dozen large and small power stations have been built one after another, producing enough electricity to supply a quarter of the total demand in New York State and Ontario, Canada. Up to now, this electric power construction, which has been built for more than 1 years, is still operating as usual, and natural gas energy has never been produced, which is a great miracle in the history of science for nearly a hundred years.
This century-old miracle in science is a design by the talented scientist Tesla in his thirties, in which he used nine patented inventions, including the AC generator and AC transmission technology invented by Tesla.
in fact, at that time, high-cost direct current was used in industry and commerce, public facilities and household appliances. Because of the loss in the circuit, a generator set must be built every kilometer when using direct current. Therefore, in the construction of Niagara Hydropower Station, it is impossible to transmit the electricity in direct current to Buffalo, New York, 35 kilometers away. Therefore, when the Niagara Hydropower Station was built, Americans adopted the alternating current power supply and transmission technology invented by Tesla, and realized long-distance power supply with high voltage electricity. This epoch-making invention not only solved the problem of long-distance power supply for Niagara Hydropower Station, but also brought people a convenient and cheap electricity environment.
Later, a bronze statue of Tesla was erected in the park of Niagara Falls to commemorate his contribution to the Niagara Hydropower Station.
selfless dedication: the patent royalty of alternating current is exempted
Tesla's lifetime invention witnessed his selfless contribution to society. Although he devoted himself to research and creation all his life, he obtained about 1 invention patents. However, in his later years, he was poor and destitute 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 numerous inventions, nothing benefits the public more than alternating current (AC) and alternating current generators. 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 23, the blackout in America and the blackout in Europe once plunged into social and economic paralysis. As early as 1882, Tesla had invented the world's first alternating current generator, and in 1885, he invented the multi-phase current and multi-phase transmission technology, which is now a widely used method to transmit electricity at 5-6Hz.
At a meeting of the US Congress on July 1th, 199, more than 1 US senators commemorated Tesla's 134th birthday, praised his contribution to electric power science, publicized how he changed people's understanding of the concept of power generation, and called Tesla a greater inventor than Edison.
after Edison invented direct current, electrical appliances were widely used, but the electricity bill was very high at the same time, so exporting direct current became the most profitable business at that time. In 1884, after Tesla left Edison, he met George Westinghouse, the head of Westinghouse, and with his support, he officially brought alternating current to the society at that time in 1888. At the opening ceremony of a World Expo in Chicago in January, 1893, Tesla demonstrated the power supply ability of alternating current to light 9, light bulbs at the same time, which shocked the audience, because direct current could not achieve this effect at all. Afterwards, Tesla won the right to host the power design of Niagara Hydropower Station.
From then on, alternating current salted fish turned over and replaced direct current as the mainstream of power supply. Tesla, on the other hand, had the patent right of alternating current, and at that time, every alternating current produced had to pay Tesla a royalty of $1. Driven by strong interests, at that time, a consortium threatened Tesla to give up this patent right and intended to monopolize profits. After many negotiations, Tesla decided to give up the patent of alternating current, on condition that the patent of alternating current will be made public permanently. Since then, he has torn off the patent of alternating current and lost the right to collect royalties. Since then, alternating current has no patent and has become a free invention.
