Nikola Tesla was born on July 10, 1856 in Smilian, then the Austrian Empire, and was a Serbian-American inventor, physicist, mechanical engineer, and electrical engineer.

Tesla grew up, due to the poor family, his father hoped that little Nicholas would inherit his father's business as a clergyman, but little Nicholas was indifferent to the gods and aspired to become an electrical engineer, so he often clashed with his father. Before the age of 17, Tesla was "caught in the evil" and immersed in the fantasy of invention and creation, and all kinds of strange phenomena often appeared in his head. At the age of 17, Tesla was amazed to find that he was able to make full use of his imagination and could perfectly depict all the details in his mind without any model, drawing or experiment, without any difference from the actual situation. Later Tesla inventions relied on this ability. Tesla said: "From the feasible theory to the actual data, there is nothing that cannot be pre-tested in the mind." The process by which people put an initial idea into practice is a complete waste of energy, money and time."
In 1875, Tesla was admitted to the Graz Polytechnic University in Austria with excellent results, and successively studied in the Department of Physics, the Department of Mathematics and the Department of Mechanics, but due to his family's poverty, he only attended the university for one year and was revoked by the Military Border Agency, and was later forced to suspend his studies because he could not afford to pay the tuition. After the suspension of school, he did not abandon his studies, but went to the university every day to audit the courses, but who would have thought that such an auditor would play a non-negligible role in the process of human industrial civilization in the future.
In 1884, Tesla was recommended by Charles Barcello to work in Edison's laboratory, and his letter of recommendation was written by Charles Barcello to Edison, which included the sentence: "I know that there are two great people, one is you, and the other is this young man."
Later, Edison arranged for him to work in a machinery company, and at first Edison just arranged for Tesla to do some simple electrical design, but because of his strong learning ability, Tesla got Edison's attention. Edison gave Tesla full trust and put him fully responsible for the design of the DC motor.
Edison had promised to reward Terrassus with $50,000 as long as he could design a DC motor, but after Terrass designed the DC motor, Edison refused to give a reward of $50,000 thinking that he was joking, but symbolically raised the salary a little, and during the company, Edison was very restrained by Tesla, and gradually, the two people who were originally trusted gradually had a gap.
Tesla then quit Edison's company and founded its own company in 1886, and with the invention of the first generator power system rectifier, Tesla obtained its first patent.
And Edison found that Tesla's alternating current threatened his monopoly position of direct current, began to suppress madly, in order to make the world disgusted with alternating current, Edison used death row inmates to do AC shock experiments, in the alternating current electrocution of death row inmates, everyone present was stunned, and these cruel pictures were also reported by the media.
Therefore, in people's minds, alternating current is synonymous with "death", and Tesla has been hit hard because of the misunderstanding of the masses, but despite this, it has not stopped The creativity of Terrass, he has improved alternating current, studied wireless transmission, wireless calls, etc.
Until 1893, Westinghouse and Edison competed for the lighting project of the Columbia Exposition, and the current war of "direct current and alternating current" was finally won by Westinghouse and Terrass's "alternating current" and obtained the lighting project of the Columbia Exposition, but unexpectedly, he actually chose to give up the patent right to permanently disclose the alternating current patent and give it to all mankind for free.
In 1935, Tesla drilled a deep well in the laboratory, he injected different frequencies into the well, in the process, Tesla found that once the frequency reached a certain index, the ground would vibrate strongly and cause the surrounding houses to collapse.
So much so that the New York Times at the time exaggerated that Tesla single-handedly induced an earthquake that almost flattened New York. Tesla also jokingly said: If I want to, within a year, I can split the earth in half! In order to develop more inventions that can change the world, most of the time is spent in the laboratory.
The mysterious Nikola Tesla was not known to the world until his death, and his miraculous research results were slowly published to the public, and it was later proved that these advanced research materials made the United States advance technology by leaps and bounds in the next thirty years, but what precious information is worth the FBI's efforts? Especially in the archives that were later declassified, the legendary "dead light" weapon is mentioned!
Dead light " weapon is a particle beam weapon often mentioned in science fiction films, Tesla's most perfect achievement is to fully master the radio technology, and the "dead light" of this devastating weapon is actually to control the high-voltage radio directional emission to any target, initially designed just to use a very low cost so that the world can use the power, but in the course of the experiment Tesla found that this directional output of electrical energy technology if applied to war will cause terrible disasters, no object can resist the power of this weapon, If attacking the human body would cause the cells of the human body to die immediately, this terrible technology allowed Tesla to seal the manuscript in a box he carried with him, and destroyed most of the information before dying.
How could Tesla have such a leading radio design? According to his answer to the reporter's interview, he said that his knowledge inspiration comes from the usual meditation, the brain in the meditative state he will enter an unknown space field, that space seems to have all the regular knowledge in our universe, he is like downloading resources to extract this knowledge from his brain, what he did is to record this and constantly improve in the experiment, including the discovery of X-rays, he believes that this knowledge should belong to all mankind, So I never thought of relying on these to get rich by sharing them for free.
At that time, the world was in the middle of World War II, and countries wanted to obtain the technology in Tesla's manuscript, so the FBI secretly put Tesla under house arrest in a small hotel in Europe for close surveillance, and after Tesla's death, all his research materials were transferred to the United States, and there was a clear instruction in an order issued by the FBI director at the time that it was later declassified: to obtain all Tesla's research manuscripts on the dead light at all costs to prevent this "precious weapon of war and defense" from falling into the hands of the enemy.
After Tesla became more and more successful, there was another person who took a fancy to him, and this person was particularly famous, named Morgan. The famous Banker of the United States, Morgan, this person has a special eye, he thinks that it will be the world of radio in the future, so he asked Tesla and said you help me study the radio tower, he gave Tesla $150,000 and a large piece of land for him to do experiments, and then Tesla went to that place to build a tower, this tower is 57 meters high, there is a hemisphere with a diameter of 20 meters, but when Tesla is going on, a scientist in Italy called Marconi first studied it. As a result, Morgan immediately terminated the cooperation with Tesla, but then Tesla sued Marconi, saying that Marconi actually used Tesla's own technology, Marconi also admitted, in 1945 the US Supreme Court declared Tesla in favor.
In the 1930s, near the end of his life, Tesla became reclusive, living alone in a hotel in New York City, occasionally making some unusual statements to the press. Because of its strange behavior, Tesla is widely considered to be the prototype of the "mad scientist". On January 7, 1943, Tesla, who had never married, died of heart failure at the New Yorker Hotel at the age of 86.
After his death, most of Tesla's belongings were confiscated by the office of foreign property — even though he was a legal U.S. citizen. The material was described as "two trucks loaded with Tesla materials, and after some time, his family was informed of some of the projects, while others remained at the Tesla Museum, in Belgrade, Serbia (where his ashes were also there)." Some of Tesla's documents and papers remain confidential, and although there have been requests through the Freedom of Information Act to explain the projects, even those that have been made public have been revised. In the end, people often don't know who Nikola Tesla was, or who he had led in developing Free Energy before his death.
