A peerless genius, unfortunately not many people remember him-----Nikola Tesla Why?

Nikola Tesla Nikola Tesla (July 10, 1856 - January 7, 1943) was the world's greatest inventor and physicist , one of 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 electronic engineering, and many of his discoveries were groundbreaking and important. 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.

On July 10, 1856, he was born in Smiljan, Croatia, Yugoslavia. His father was a priest and his mother was the inventor of the eggbeater. 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 kept comming to me and made me almost unable to 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 his own benefit. profit. Tesla's most prolific creative years were spent in the United States. Much of it remains 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.

The heresy of the era: the invention of alternating current 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 Nicola Nikola Tesla was a major "heretic" in the scientific community. The alternating current (AC) he invented directly affected human life safety, and he repeatedly demonstrated how dogs and cats died instantly after passing through AC (the "electric chair" was also called the death penalty for this reason). 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 direct current 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 Geovge Westinghouse, an entrepreneur from 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 and 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.

Centennial-marked Niagara Hydropower Station

If you have ever been to Niagara Falls (Niagara Falls) in the United States, I believe everyone will sincerely admire 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 when he was in his thirties. It used 9 of his patented inventions, including Tesla's invention of alternating current generators and alternating current transmission 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, people erected a bronze statue of Tesla in the park of Niagara Falls to commemorate his contribution to the Niagara Hydropower Station.

Selfless dedication: exemption from patent royalties on alternating current

Tesla’s lifetime of inventions bear witness to his selfless contribution to society. Although he continued to devote himself to research and creation throughout his life, and obtained about 1,000 invention patents. But in his later years, he was in poverty 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 have 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 contributions to electricity science, and promoted how he changed mankind's understanding of power generation. The understanding of the concept praised Tesla as a greater inventor than Edison.

After Edison invented direct current, electrical appliances were widely used, but the electricity bill was very high, so 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 society at that time 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 profits. 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 on alternating current and lost the right to collect royalties. From then on, alternating current was no longer patented and became a free invention.
