In the early days of World War II, did Tesla invent many super powerful things?

Open Baidu search and enter Nikola Tesla (to avoid searching for American electric cars, please enter the full name) and you will see an omnipotent figure. A superman with special powers. Some people suspect that he is an advanced creature from an alien planet. Others believe that many mysterious events that occur on the earth are related to his research. He can completely defeat scientists such as Einstein and Hawking. He and Darwin , Tibetan Mastiff together are considered to be fully capable of killing the universe in an instant.

So how awesome is the real Tesla? This article will try to tell you about the real Nikola Tesla and shatter some rumors about him.

Some people would say that without Edison, perhaps humans could only use candlelight to illuminate the night. But some people will say that if there was no Edison, there would still be Tesla! Tesla is Prometheus, the God of Electrical and Electronics sent to mankind by God! There are no "ifs" in history. In the process of the development of wireless communications and power systems, we have both Edison and Tesla. God sent two great inventors to mankind.

The protagonist of this post, who was born in Serbia and has had a strong curiosity about electricity since childhood, pursued his American dream and joined his idol - Edison, who was already famous at that time. Edison called him "our Parisian boy." Edison immediately discovered that this young and eccentric Serbian engineer was a very useful talent, so he entrusted him with the important task of improving the imperfect DC power supply equipment and verbally promised a reward of US$50,000. Tesla worked diligently and in less than a year designed 24 different machines to replace the old ones. But when he mentioned the promised bonus to Edison, what he got was a frivolous sentence from Edison: "Ah, you don't understand our American humor!"

Tesla was even more unhappy. Unfortunately, no one in Edison's company was willing to accept his views and suggestions on alternating current. Tesla had completed the idea of ??an AC induction generator in his mind as early as his student days. He came to Edison with his "dream of communication". However, the development of technology is not only related to the technology itself. Market trends, business operations, company development, investors' interests, and many other factors are involved. There are always similarities in history. At the end of the 20th century and the beginning of the 21st century, the world staged an Internet war. More than 100 years ago, there was a "current war" between Tesla and Edison.

Of course Edison would not accept Tesla's whims about alternating current. It was a period when his DC power supply system was booming, and Edison himself had become rich and became a business celebrity. .

In Edison's company, Tesla could not realize his dream of alternating current, and was angered by Edison's failure to keep his promise. Therefore, Tesla resigned and left the Edison Company in anger. Of course, Tesla paid a heavy price for his reckless and hasty decisions. His life within a year or two after his resignation was entirely supported by manual labor. Later, even Tesla's foreman discovered that this young Serbian man was not an ordinary, serious worker, but at least an experienced engineer or even an electrical expert. Therefore, the foreman introduced him to the important people he knew. Finally one day, Tesla had the opportunity to realize his electrical dream again. He had his first electrical laboratory at 87 Liberty Street, and he began to develop a complete set of AC power supply equipment that had been completed many times in his mind.

Compared with direct current, alternating current has many advantages in power generation and distribution, which is why Tesla invented the three-phase alternating current and its induction motor equipment, as well as the 110 volt, 60 hertz The reason why power supply standards are still used today in the United States.

The multiple alternators invented by Tesla can easily convert mechanical energy, chemical energy, etc. into electrical energy; after the AC system uses the principle of electromagnetic induction to build a transformer, it can easily increase and decrease the voltage. , to achieve the purpose of long-distance transmission. Because transmission is carried out under high voltage, loss can be reduced and the transmission can be carried far. The direct current that Edison advocated could only generate electricity at a lower power and voltage. A generator had to be installed every few dozen meters along the entire line.

Of course, from a physical point of view, DC transmission also has its advantages. There is no loss due to capacitive current; there is no reduction in the effective area of ??the wire due to the skin effect; no AC transmission is required. synchronization adjustment and so on.

Later, alternating current gradually replaced direct current as the mainstream power supply. Tesla owned the patent for alternating current. At that time, Tesla had to pay a patent fee 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 its patent rights on alternating current, on the condition that the patent on alternating current would be made public permanently.

From using rotating magnetic fields to improve motors and inventing AC induction motors and generators, to creating the first radio remote control machine, inventing and promoting AC systems, inventing Tesla coils, creating artificial lightning, and researching the world Wireless power supply system, most of Tesla's invention patents are related to electricity. He is worthy of being a pioneer in the field of electrification and a genius born for electricity.

Towards the end of his life in the 1930s, Tesla became reclusive and behaved strangely. On January 7, 1943, Tesla, who never married, died of heart failure in a New York hotel at the age of 87. Tesla was a peerless genius, a scientific master who had been forgotten by the world, and a great man who devoted his life to the whole world rather than to a specific country.

Another historic event regarding alternating current was the completion of the Niagara Hydropower Station designed by Tesla at Niagara Falls in November 1896. After the power station was completed and powered, various media outlets excitedly reported: "As soon as the switch was closed, a raging waterfall flowed to the top of the mountain." To this day, this power system, which was built for more than 100 years, is still operating as usual without interruption. The production of natural energy from land can be described as a miracle in the history of science in the past century. Later, a bronze statue of Tesla was erected in Niagara Falls Park to commemorate his selfless contribution to the electrification of mankind.

However, the above deeds are far from the omnipotent Tesla on the Internet, so the Tesla who can easily create the Tunguska explosion, the one who created anti-gravity and time travel Wait, how did the highly theoretical Tesla appear?

The answer is obvious - conspiracy theorists

In the mouths of conspiracy theorists, Tesla has become a widely suppressed and persecuted genius whose talent was not appreciated. They lamented that if his If theories are not buried, then humans have already achieved many things that are still seen in science fiction movies. Those who suppressed Tesla include: Edison, Einstein, the American consortium, the FBI, the U.S. government, etc. Tesla’s research subjects are very broad, including electromagnetic theory (X-rays, lasers, death rays, etc.), gravity theory (the NB theory that kills the most in a flash), time travel theory (unknown specifics), and high-voltage alternating current wireless transmission theory ( It is said that the Tunguska explosion was caused by him while doing related experiments) and so on.

The following will crush these rumors one by one for everyone.

1. Tesla invented alternating current and alternator.

When electromagnetic induction was discovered, the method of generating alternating current was discovered. Early finished products were developed by Michael Faraday and Paulette Pixie, among others. Among them, Polit Pixie built the first AC motor based on Faraday's principle in 1832.

The cornerstone of modern society is the three-phase alternator, whose inventor is Dobrovolsky, the father of modern alternating current.

In addition, even if Tesla invented the three-phase alternator, there is no strange logic of "if we are still using alternating current, we must thank Tesla". This obviously lacks the understanding of science and technology. enough knowledge of history.

The emergence of three-phase motors is the result of the advancement of electromagnetics and application technology. There are countless names worth remembering before this.

As the famous European proverb goes: A dwarf standing on a giant's body can see further.

It should be noted here that in 1891, Nikola Tesla patented a "high frequency" (15,000 Hz) alternator.

2. Tesla won the Nobel Prize in Physics many times throughout his life (more commonly said is 11 times, and there is also a theory that it was in 1912 to encourage Edison and Tesla’s contributions to electrical fields. , were awarded the Nobel Prize in Physics at the same time, but both men refused to accept the award due to their grievances).

People who hold this view can go to the Nobel official website to check the results at a glance. He boasted that Tesla had won the Nobel Prize 11 times in his life, but Tesla had all given up or refused to accept the award.

This statement is really dumbfounding. Tesla was a great engineer, but when it came to theoretical physics he was just a layman. In the international physics community at that time, quantum physics and the theory of relativity echoed each other. Both theories used extremely complex mathematical languages. However, Tesla’s theoretical knowledge was very weak and lacked corresponding theoretical foundation. Newton’s integrals, Leibniz's differential calculus and Maxwell's field theory were not involved in his theory. He used the simple mathematics of ancient Greek mechanics.

And the widely circulated rumors about the Nobel Prize in 1912 are actually just rumors.

In 1912, Edison and Tesla were not even nominated. The nominees include Einstein, Lorentz, Planck, Mach, Poincaré and other outstanding people, who are more qualified to win the prize than Edison Tesla (several of them did win the prize later), but the 1912 Physics Prize It was awarded to this classmate Darren. One possible reason is that Darren is a Swede, and at that time no Swede had won the physics prize. The Royal Swedish Society, which is responsible for judging the prize, wanted to save some face for the country - but these are all conjectures. Because this award-winning theory is really not flattering, the reason turned out to be that he "invented the automatic regulator and the gas gathering device for combined use in lighthouses and buoy lighting." With this device, lighthouses and lighting buoys can automatically light up when it gets dark and turn off when it gets light. They can run unattended for more than a year and greatly reduce fuel consumption. Even the media can't stand this level. , so he said that if this theory can win an award, then the spoon that opens the can can also win. Some even said that the Nobel Prize might as well be awarded to Edison and Tesla. This meme was passed around and turned into a rumor that Tesla won the prize.

3. Tesla’s theory instantly killed scientists such as Einstein and Hawking (this rumor even turned into Einstein suppressing Tesla, and Tesla and Einstein became lifelong enemies. In order to suppress Tesla, the U.S. government even created multiple versions of a scientific image like Einstein)

For such a statement, I can only lament the poor scientific literacy of the Chinese people, which is so bad that it is shocking (Of course, the special bragging may not be limited to Chinese people).

As for Tesla’s theory, you can refer to the previous article. Don’t say that he competed with Xiao Ai. At that time, his theory was not as good as that of a college student with higher education. And the grudge between him and Xiao Ai was even more illusory. Tesla and Xiao Ai are basically contemporaries, but there is almost no intersection between them. There is a joke on the Internet about Tesla writing a letter to congratulate Xiao Ai after she won the Nobel Prize. I don’t know whether it is true or not. If it is true, then this is the only intersection between them.

4. The Tunguska explosion was created by Tesla while doing related experiments (Wardenclyffe Tower).

“I could split the world in half, but I would never do it. My main goal is to spread new ideas and make them become reality. I very much hope that they can become the inspiration for future researchers. A starting point.” I don’t know if this sentence was said by Tesla himself, or if it was trumpeted by Tesla. I guess it was probably trumpeted by Tesla.

In June 2009, the "People" column of CCTV's 10 science and education channels launched a two-episode documentary - "Science Superman Nikola Tesla". The entire film revolves around the famous Tunguska explosion in Russia, and it is believed that Tesla "bears full responsibility for this Tunguska disaster." Although the film is full of interviews with "experts", most of the content has no scientific basis, and even It can be said to be pseudoscience, and the connection between the Tunguska explosion and Tesla is more of a forced one.

5. Tesla was suppressed and his research theories were hidden.

This is a common view among conspiracy theorists. In fact, in other fields, conspiracy theorists link various mysterious events with the US government, and the US government has repeatedly acted as an obstacle to human development. The villain. In Tesla-related rumors, the FBI has naturally become the culprit. Tesla's lifetime research results, filled with 80 boxes of information, were all confiscated by the FBI (it is also rumored that most of Tesla's scientific research results were lost in a fire), and this information is still under the strict control of the U.S. government. It is under control and cannot be made public. There is no so-called suppression of Tesla in the physics community. In fact, at the International Conference on Weights and Measures in Paris in 1960, Tesla was named the international unit for deriving magnetic flux density or magnetic induction intensity. To commemorate his great contributions to electrical engineering.

6. Tesla discovered X-rays, invented radio communication technology, as well as laser technology, death ray and other black technologies.

I don’t know where this rumor came from. It is even said that Tesla discovered and took the first X-ray photo and mailed it to R?ntgen at the time. R?ntgen read it Tesla was highly praised, but Tesla himself believed that X-rays were dangerous rays and refused to continue research. Therefore, all achievements in X-rays are attributed to Roentgen.

As for radio communication technology, I still clearly remember hearing "Mr. Marconi is a DONKY" in a documentary one year. Yes, this is what Tesla said. He stubbornly used arc discharge instead of resonant circuits to generate electromagnetic waves for communication. Marconi used his own method to take the lead in realizing transoceanic communication, but was criticized by Tesla. Personal attack.

As for black technologies such as death rays, it is said that Tesla invented a super powerful ray that could kill nuclear weapons instantly, and provided it to the U.S. military at the time, but the military could not see it. I understand that there is no explanation for the reason. Rumors of this level should be treated as a joke.

There are also some rumors about Tesla, most of which are too ridiculous to be worth refuting. And Tesla’s titles that Te boasts about include the father of the electrical revolution, the father of the modern electric motor, the father of alternating current, the father of radar, the father of radio, the father of X-rays, the father of wireless power transmission... .Wait, it makes me want to vomit. Is this what you call dry information and popular science? Can you tell me the sources of the serious references for that painting? Can you tell me who gave him the title of the father of electricity? After all this going on, it was your special fans who awarded you the title? It's really awesome. I have an electrical manual at hand. Can Te Fan come and teach me where Te God’s contribution is so that I can learn from it?

Okay, are you wronging your idol by saying that he has no place in the history of science? No, can you please clearly distinguish the difference between science and engineering? You are now an adult, but you still can’t tell the difference between science and engineering? If we insist on talking about scientific achievements, do fans dare to say that their idol's scientific achievements are higher than those of Edison, whom they despise? But Edison also observed the phenomenon of thermal electron emission (thermionic emission) in 1875, also known as (Edison effect)! Is this result awesome? Owen Richardson won the Nobel Prize in Physics in 1901 for explaining this phenomenon! Of course, the special fans may not like it. Compared with the special ball lightning, this is nothing! But don’t forget that the American Fleming later relied on this effect to invent the vacuum tube that determined the death of the radio electronics student. Therefore, Wiener called this effect the greatest achievement of Edison’s life (Source: the care and feeding of ideas page 64) . Who is Weiner? Did the founder of modern cybernetics understand it? Are you a scientific giant of the 20th century? Are all your fans combined equal to one of Weiner's hairs?

OK, I’m tired of verbosely. There is no intention to black Tesla. I just want to remind some Tesla fans not to fool the public with some pictures of God with the words "Father of Various Things" and "Ball Lightning" on them. Your idol has nothing to do with the various titles on that picture. There is also ball lightning. Let me tell you that until today, there is no laboratory on earth that can create artificial ball lightning. So don't be obscene. The foreman asked you to move bricks. Hurry up and do something serious and stop being crooked!

"What achievements did Hawking have? Hawking was all based on his own imagination, but it was of no use. The black hole and Big Bang cosmologists were all based on his own imagination and some microwave tests."

p>

From this sentence, you can know the level of your scientific literacy. I have no intention of telling you what science is and what a scientist is, and I don’t have the time.

It’s just that you have to understand that theoretical physicists like Hawking have a solid foundation in mathematics and physics. Any of their theories are based on mathematical language, and their theories are based on It has been demonstrated repeatedly, in other words, it is mathematically established, theoretically self-consistent, and consistent with the scientific logical derivation process. So is Hawking's theory a scientific theory? Unfortunately, many of his theories cannot be verified at the current scientific level, which is why his theory cannot become a standard scientific theory.

Then let’s go back and look at Tesla’s theory. Tesla was not a person majoring in theoretical physics at all. He did not have any basis for theoretical research. In other words, he had no scientific literacy. not enough. His so-called theory (whether it is really his own or fabricated by a special fan) does not have any mathematical derivation process at all. Even if it does, it only uses simple mathematics from ancient Greece, Newton's integrals, Leibniz's The differential calculus and Maxwell's field theory are not very involved in his theory, so the so-called research level of this level can be imagined.

As for you saying that Baidu Encyclopedia did not say that he invented alternating current, I did not say that Baidu said that he invented anything, but the fans and boasters said that he invented this and that. There are also the scientific fields that Tesla was involved in that you mentioned later. There are indeed many fields that he was involved in, but in many fields his theories were worthless, and he even stubbornly persisted in the wrong direction. Simply put, electromagnetic wave communication technology, he Stubbornly using arc discharge instead of resonant circuits to generate electromagnetic waves for communication, Marconi used his own method to take the lead in realizing transoceanic communication and obtained relevant patents earlier than him. As for the death rays and anti-gravity flying saucers, it’s even worse!

7. British scientist Watt invented radar. Tesla had already come up with the idea of ??radar, but was suppressed by Edison and was not used.

The concept of radar was proposed very early and was eventually promoted by many people.

1922: Marconi proposed a new concept: when visibility is extremely low, radio waves can be emitted to detect ships by "echoes" (actually reflected waves).

1922: The Americans Taylor and Young proposed equipping two warships with high-frequency transmitters and receivers to search for enemy ships.

1924: British Appleton and Barnett measured the height of the ionosphere by reflecting radio waves. Blair and Duff in the United States used pulse waves to measure the Heaviside layer.

1931: The U.S. Naval Research Laboratory developed radar using the beat frequency principle and began to use the transmitter to emit continuous waves. Three years later, it switched to pulse waves.

1935: A.L. Samuel developed the first model of a multi-cavity magnetron. In the same year, French Gutton used a magnetron to generate a 16-centimeter wavelength. On November 29, German H.E. Hollmann registered a patent for a more outstanding multi-cavity magnetron.

1939: H.A.H. Boot and J.T. Randall made a multi-cavity magnetron that fully met practical standards, which led to the rapid advancement of decimeter-level radar technology in the United States during the war. However, the Soviet Union claimed in publications published in the 1940s that two Soviet scholars had first made a multi-cavity magnetron in 1936, in order to attribute its invention to themselves (similar claims were made in aircraft, radio, etc. Honors are common), but it cannot conceal the fact that the Soviet Union's radar and radio technology was backward during the war. It became the only country among the warring countries to install meter-wave radars on night fighters during World War II, and its battleships were only equipped with imported carrier-based radars after the war.

Radar began to be used peacefully as a maritime detection tool at night and in foggy weather.

January 1936: The British W. Watt (also translated as Robert Watson Watt) set up the first British radar station on the coast of Sofke. The British Air Force added five more, and they played an important role in World War II

The first radar station was erected by Watt. It can only be said that Tesla also had such an idea, but The idea and execution are still different.

8. Tesla built the first hydroelectric power station

It should be said that Tesla's AC technology was used in the first hydroelectric power station.

Niagara Falls was to build the world's first hydroelectric power station, and the alternating current system was chosen because of its affordability and ease of manufacture. Westinghouse handed over the design and manufacturing tasks to Scottish engineer George Forbes. The latter made a device using three Tesla alternators, each with a power of 110 kilowatts.

9. Tesla created ball lightning in the laboratory.

This rumor may come from the picture below:

The mysterious man behind the picture is Tesla, and the focused, charming and electrifying man in the front is actually Mark. Twain, can you believe it?

As for you asking me why these two are in the same movie, I won’t tell you that they are good friends.

Of course, it is obvious that the thing we see in Mark's hand in the photo may be... I guess, isn't this just a light bulb?

Of course Tebu would not allow something as common as a light bulb to appear in Tesla's laboratory. You must know that the light bulb was invented by Tesla's mortal enemy, Edison. Therefore, in order to make this picture look more mysterious, the experts invented the ball lightning. In order to allow the great Mr. Mark Twain to continue to expose the evils of capitalist society without being electrocuted by Tesla, the experts did not hesitate to change the article of this critical realist writer and let him explain Tesla, the black man. Technology testifies.

In fact, ball lightning is difficult to manufacture even under today's laboratory conditions. It is difficult to imagine that in an era when there was no basis for electronic components, Tesla relied on It can be produced by oneself and with meager financial resources. What's even more exaggerated is that the ball lightning Te boasts can be freely played in Tesla's hands without hurting anyone.
