Electronic component joke

Open Baidu search and enter nikola tesla (please enter your full name to avoid finding American electric cars), and you will see an omnipotent figure. A superman with special functions, some people suspect that he is a higher creature from another planet, and some people think that many mysterious events on earth are related to his research. He can completely explode scientists such as Einstein and Hawking, and together with Darwin and Tibetan Mastiff, he is considered to be a person who is fully capable of killing the universe.

So how NB is the real Tesla? This article will try to tell you the real nikola tesla and crush some rumors about him.

Some people will say that without Edison, maybe human beings can only light up the night by candlelight. But some people will say that without Edison, there would be Tesla! Tesla is Prometheus, God's god of electricity and electrons! History has no "ifs". In the development of radio communication and power system, we have both Edison and Tesla. God sent two great inventors to mankind.

Born in Serbia, the protagonist of this post has a strong curiosity about electricity since he was a child. With his American dream, he took refuge in his idol, Edison, who was very famous at that time. Edison called him "our Paris boy". Edison immediately discovered that this eccentric young Serbian engineer was a very useful talent, so he entrusted him with the task of improving the imperfect DC power supply equipment and verbally promised to reward him with 50 thousand dollars. Tesla worked hard and designed 24 different machines to replace the old ones in less than a year. But when he mentioned the promised bonus to Edison, he got Edison's light sentence: "Oh, you don't understand our American humor!" " "

What makes Tesla even more unhappy is that no one in Edison's company is willing to accept his views and suggestions on alternating current. Tesla completed the idea of AC induction generator in his mind as early as his student days. He came to Edison with a "dream of communication". However, the development of technology is not only related to the technology itself, but also related to the market trend, the operation of business, the development of companies and the interests of investors. There are always similarities in history. At the end of the 20th century, from 265,438 to the beginning of the 20th century, the world staged an Internet war, and more than 65,438+000 years ago, there was also a "current war" between Tesla and Edison.

Edison certainly won't accept Tesla's whimsy about alternating current. At that time, his DC power supply system was booming, and Edison himself became 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 bad faith. So Tesla resigned in a rage and left Edison. Of course, Tesla paid a heavy price for his reckless decision, and his life within one or two years after his resignation was supported by manual labor. Later, even Tesla's foreman discovered that the young Serb was not an ordinary and diligent worker, but at least an experienced engineer and even an electrical expert. Therefore, the foreman introduced him to the big shots he knew. Finally, one day, Tesla had a chance to reunite his electric dream. He had his first electrical laboratory at No.87 Liberty Street, and he began to develop a set of AC power supply equipment that he had 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 three-phase alternating current and its induction motor equipment. The United States still uses the power supply standard of 1 10 volt and 60 Hz.

Many alternators invented by Tesla can easily convert mechanical energy and chemical energy into electrical energy. After the transformer is built by using the electromagnetic induction principle in AC system, the voltage can be easily raised and lowered to achieve the purpose of long-distance transmission. Because the transmission is carried out at high voltage, the loss can be reduced and the transmission can go far. The direct current advocated by Edison can only generate electricity with low power and low voltage, and a generator must be installed every tens of meters along the whole line.

Of course, from a physical point of view, DC transmission also has its advantages, and there is no loss caused by capacitive current; The effective area of the conductor will not be reduced due to skin effect; AC transmission does not need synchronous regulation and so on.

Later, alternating current gradually replaced direct current as the mainstream of power supply. Tesla has the patent right of alternating current, and at that time, every alternating current produced must pay Tesla a patent fee of $65,438 +0. Driven by strong interests, a consortium threatened Tesla to give up this patent right with the intention of monopolizing profits. After many negotiations, Tesla decided to give up the patent of alternating current, provided that the patent of alternating current was made public permanently.

From the invention of AC induction motor and generator by improving motor with rotating magnetic field, to the manufacture of the first radio remote control, the invention and popularization of AC system, the invention of Tesla coil, the manufacture of artificial lightning and the research of global wireless power supply system, most of Tesla's invention patents are related to electricity. He is a pioneer in the field of electrification and a genius born for electricity.

In 1930s, near the end of his life, Tesla became a hermit and behaved strangely. 1943 65438+1On October 7th, Tesla, who had never been married, died of heart failure in a hotel in new york at the age of 87. Tesla is a peerless genius, a master of science forgotten by the world, and a great man who devoted his life to the whole world instead of serving a particular country.

Another historic event about alternating current is that the Niagara Hydropower Station designed by Tesla was completed at Niagara Falls in 1896+065438+ 10. After the power station was completed and delivered, the media reported excitedly: "As soon as the switch is turned on, the raging waterfall flows to the top of the mountain." Today, this power system, which has been built for more than 100 years, is still running as usual and has never stopped producing natural gas energy, which is a great miracle in the history of science in the past hundred years. Later, a bronze statue of Tesla was erected in Niagara Falls Park to commemorate his selfless dedication to the electrification of mankind.

However, the above deeds are far from the omnipotent Tesla on the Internet. So how did Tesla, who could easily create the Tunguska Big Bang and Tesla, who created these lofty theories of anti-gravity and time travel, appear?

The answer is obvious-conspiracy theorists.

In the mouth of conspiracy theorists, Tesla has become a prodigy who has been widely suppressed and persecuted and has no talent. They think that if his theory had not been buried, then human beings would have achieved a lot of things that are still seen in science fiction movies. The people who suppressed Tesla included Edison, Einstein, American consortium, the FBI and the US government. Tesla's research objects are very extensive, including electromagnetic theory (X-ray, laser, dead light, etc. ), gravity theory (NB theory that kills wide phase), time travel theory (details are unknown), high-voltage AC wireless transmission theory (it is said that Tunguska Big Bang was done by him when he was doing related experiments) and so on.

Next, I will crush these rumors for everyone.

1, Tesla invented alternating current and alternator.

When electromagnetic induction was discovered, the method of generating alternating current was discovered. The early products were developed by michael faraday and Bopak Rongsu Pixar. Among them, Bopu Rongsu Pixii manufactured the first AC motor based on Faraday principle in 1832.

The cornerstone of modern society is a three-phase alternator, which was invented by Dobro Voski, the father of modern alternating current.

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

The appearance of three-phase motor is the result of the progress of electromagnetism and applied technology. Before that, there were countless names worth remembering.

As the famous European proverb says, only a dwarf who stands on a giant can see farther.

It should be noted that in 189 1 year, nikola tesla obtained the patent of "high frequency" (15000Hz) alternator.

2. Tesla won the Nobel Prize in Physics many times in his life (there are many sayings that it is 1 1 times, and there is another saying that it was 19 12 years. Edison and Tesla were awarded the Nobel Prize in Physics at the same time in order to encourage their contributions to electricity, but both of them refused to accept the prize because of feuds).

People who hold this view can go to Nobel official website to see the results at a glance. It is said that Tesla won the Nobel Prize 65,438+065,438+0 times in his life, but Tesla gave way or refused to accept the prize. This statement really makes people laugh and cry. Tesla is a great engineer, but he is just a layman in theoretical physics. In the international physics field at that time, quantum physics and relativity echoed at a distance, and both theories used extremely complicated mathematical languages. However, Tesla's theoretical knowledge is very imperfect and lacks the corresponding theoretical basis. Newton's integral, Leibniz's differential and Maxwell's field theory were not involved in his theory, but he used the simple mathematics of ancient Greek mechanics.

The widely circulated rumor about the Nobel Prize 19 12 is actually just a rumor.

19 12 Edison and Tesla didn't even nominate. Nominees include Einstein, Lorenz, Planck, Mach, Poincare and other great men, who are more qualified to win the prize than Edison Tesla (there were indeed several awards later), but the 19 12 physics prize was awarded to this Darren classmate. One possible reason is that Darren was Swedish. By that time, no Swede had won the physics prize, and the Royal Swedish Society, which was in charge of awarding prizes, wanted to save face for his country-but these were all guesses. Because this award-winning theory is really flattering, the reason turned out to be that he "invented the automatic regulator and gas collecting device for lighthouse and buoy lighting". With this device, the lighthouse and lighting buoy can be automatically turned on at dark and turned off at dawn, and can be unattended for more than one year, greatly reducing fuel consumption. This level is invisible to the media, so if this theory can win the prize, so can the spoon that can be opened. What's more, it is said that the Nobel Prize is not as good as being awarded to Edison and Tesla, and this stalk has become a rumor that Tesla won the prize.

3. Tesla's theory killed scientists such as Einstein and Hawking (this rumor even turned into Einstein's suppression of Tesla, Tesla and Einstein became lifelong enemies, and even the US government set up many versions of Einstein's scientific image to suppress Tesla).

For this statement, I can only feel that the scientific literacy of China people is appalling (of course, China people may not be the only one).

As for Tesla's theory, you can refer to the last one. Don't say he played a trick with Xiao Ai. At that time, his theory was not even as good as that of a college student with higher education. The feud between him and Xiao Ai is even more false. Tesla and Xiao Ai are basically contemporaries, but there is almost no intersection between them. There is a joke on the Internet that Tesla wrote a letter to congratulate Xiao Ai after winning the Nobel Prize. I don't know if it's true or not. If it is true, then this is the only intersection between them.

4. The Tunguska Big Bang was made by Tesla while doing relevant experiments (Walden Creff Tower).

"I can split the world, but I will never do that. My main goal is to spread new ideas and make them come true. I very much hope that they can become a starting point for future researchers. " I don't know if this sentence was said by Tesla himself or blown out. I think it's probably a special blow to embellish it.

In June 2009, CCTV 10 set of science and education channel People released two documentaries-nikola tesla, Superman of Science. The whole film revolves around the famous Tunguska explosion in Russia, and thinks that Tesla "should take full responsibility for this Tunguska disaster." Although the film is full of interviews with "experts", most of the content has no scientific basis, even pseudoscience. Linking the Tunguska Big Bang with Tesla is even more delaying.

5. Tesla was suppressed and its research theory was hidden in the snow.

This is the common view of conspiracy theorists. In fact, in other fields, conspiracy theorists say that all kinds of mysterious events are related to the US government, which has repeatedly played a negative role in hindering human development. In Tesla's related rumors, the FBI naturally became the culprit. The research results of Tesla's life are filled with 80 boxes of materials, all of which were seized by the FBI (there are also rumors that most of Tesla's research results were lost in a fire). These materials are still under the strict control of the US government and cannot be made public. However, there is no so-called suppression of Tesla in physics. In fact, at the International Metrology Conference held in Paris in 1960, Tesla was named as an international unit for deriving magnetic flux density or magnetic induction intensity to commemorate his great contribution to electrical engineering.

6. Tesla discovered X-rays and invented radio communication technology, as well as black technologies such as laser technology and dead light.

I don't know where this rumor came from. What's more, Tesla even claimed that he found and took the first X-ray photo and mailed it to Roentgen at that time. Roentgen praised Tesla after reading it, but Tesla himself thought that X-ray was a dangerous ray and refused to continue his research, so all the achievements of X-ray were attributed to Roentgen.

As for radio communication technology, I still clearly remember hearing in a documentary one year that "Mr Marconi is a Donkey". Yes, that's what Tesla said. He stubbornly used arc discharge to communicate instead of electromagnetic wave generated by resonant circuit. Marconi took the lead in realizing overseas communication in his own way, but was personally attacked by Tesla.

As for black technology such as death ray, it is said that Tesla invented a super-strong ray, which is powerful and kills nuclear weapons. It was provided to the US military at that time, but the military did not understand it. Rumors of this degree should be treated as jokes.

There are also some rumors about Tesla, most of which are too absurd to refute. Tesla's titles on special mouthpiece, such as father of electric revolution, father of modern motor, father of alternating current, father of radar, father of radio, father of X-ray, father of wireless transmission, etc. It makes me sick. Is this what you call dry goods plus science? Can you tell me the main source of that painting? Can you tell me who gave him the title of father of electricity? Did your special powder give you this title? That's great. I have an electrical manual at hand. Can you teach me how to point out the contribution of the special god so that I can study it?

So, is it unfair to say that your idol has no place in the history of science? No, please tell the difference between science and engineering. Adults, do you still have to clean up engineering? Insist on scientific achievements. Does Tefen dare to say that his idol's scientific achievements are higher than Edison's? But Edison also observed thermionic emission in 1875, which is the so-called Edison effect! Is this achievement awesome? 190 1 owen richardson won the nobel prize in physics for explaining this phenomenon! Of course, the special powder may be disdainful. Compared with the spherical lightning of the special god, this is nothing at all! But don't forget, American Fleming later invented the vacuum tube that decided the life and death of radio electrons by this effect, so Wiener called this effect Edison's greatest achievement in his life (source: care and nurturing of thoughts, page 64). Who's wiener? The founder of modern cybernetics, understand? Did you build the master of science in the 20th century? Can your special powder add up to a Weiner's hair?

Well, I'm tired of talking so much. There is no meaning of black Tesla. I just want to remind some Tesla brain-dead powder, and don't use words like "father of all kinds" and "ball lightning" to fool the public. Your idol has nothing to do with all the titles in that picture. It's also spherical lightning. I tell you, until today, there is no laboratory on earth that can make spherical lightning. So don't be paranoid. The foreman told you to move bricks and get down to business.

"Hawking's achievements are all based on his own imagination YY, but they are useless. What black hole big bang cosmologists rely on their own imagination and rely on some microwave tests. "

From this sentence, you will know what level of your scientific literacy is. I'm not talking about telling you about science, what is science and what is a scientist, and I don't have the time.

You just need to understand that theoretical physicists like Hawking have a solid foundation in mathematics and physics, and any of their theories are based on mathematical language, and their theories have been repeatedly demonstrated, in other words, they are mathematically established, self-consistent in theory and in line with the process of scientific logic deduction. So is Hawking's theory a scientific theory? Unfortunately, many of his theories can't be verified under the existing scientific level, which is also the reason why his theories can't become standard scientific theories.

Then we will look back at Tesla's theory. Tesla is not a professional in theoretical physics at all. He has no theoretical basis at all. In other words, his scientific literacy is not enough. His so-called theory (whether it is really his own or specially made up) has no mathematical derivation process at all, and even if it does, it only uses simple mathematics in ancient Greece. Newton's integral, Leibniz's differential and Maxwell's field theory were not involved in his theory, so the so-called research level of this level can be imagined.

As for you saying that Baidu Encyclopedia didn't say that he invented alternating current, I didn't say that Baidu said that he invented anything, but fans and fans said that he invented this and that. There is also the scientific field that Tesla mentioned later. It is true that he covers many fields, but in many fields his theory is worthless, and he even stubbornly sticks to the wrong direction. Simply speaking, electromagnetic wave communication technology, he stubbornly used arc discharge instead of resonant circuit to generate electromagnetic waves for communication. Marconi took the lead in realizing overseas communication in his own way and obtained relevant patents before him. As for what death ray, anti-gravity flying saucer, that is even more hehe!

7. British scientist Watt invented radar. Tesla had long thought of the idea of radar, but Edison suppressed it and didn't use it.

The concept of radar was put forward long ago, and finally it was popularized by many people.

1922: Marconi put forward a new concept: in the case of extremely low visibility, radio waves can be emitted to detect ships through "echoes" (actually reflected waves).

1922: Taylor and Yang of the United States suggested that two warships should be equipped with high-frequency transmitters and receivers to search for enemy ships.

1924: The height of the stage was measured by radio waves reflected from the ionosphere in appleton and barnett, England. Blair and Duff in the United States use pulse waves to measure the Haveser layer.

193 1 year: The U.S. Naval Research Laboratory developed a radar based on the beat frequency principle. The transmitter started to emit continuous waves, and three years later it switched to pulse waves.

1935: A.L.Samuel first developed the model of multi-cavity magnetron. In the same year, Gutton of France used a magnetron to generate a wavelength of 16 cm. 1 1 On 29th, German H.E. Hollmann registered a better multi-cavity magnetron patent.

1939: H.A.H Bout and J.T. Landauer made a multi-cavity magnetron that completely reached the practical standard, thus making the decimeter radar technology in the United States advance by leaps and bounds during World War II. However, in the publication published by the Soviet Union in the 1940s, it was claimed that two Soviet scholars had made multi-cavity magnetrons as early as 36 years ago, so as to claim their inventions under their own names (similar statements are common in many honors such as airplanes and radios), but it could not conceal the fact that the Soviet Union was backward in radar and radio technology during the Great War. During World War II, it became the only country among the belligerents to install meter-wave radars on night fighters, and its battleships only installed imported shipborne radars after the war.

As a maritime detection tool at night and in foggy days, radar has been used peacefully.

1936 65438+1October: Englishman w watt (also translated as Robert Watson Watt) set up the first British radar station on the coast of Suffolk. The British Air Force added five more aircraft, which played an important role in the Second World War.

The first radar station was built by Watt. It can only be said that Tesla also has such an idea, but the idea is still different from that made.

8. Tesla built the first hydroelectric power station.

It should be said that the first hydropower station used Tesla's alternating current technology.

Niagara Falls wants to build the world's first hydroelectric power station, and the AC system is chosen because of its economy and easy manufacture. Westinghouse handed over the design and manufacturing tasks to Scottish engineer George Forbes. The latter made a set of equipment with three Tesla alternators, each with a power of 1 10 kW.

9. Tesla made spherical lightning in the laboratory.

This rumor may come from the following picture:

The mysterious person behind the picture is Tesla, and the dedicated, fashionable and charged person in front is actually Mark Twain. Can you believe it?

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

Of course, obviously, what we see in Mark's hand from the photo may be ... Shit, isn't this just a light bulb?

Of course, ordinary things like light bulbs are not allowed in Tesla's laboratory in Feng Te. You know, the light bulb was invented by Edison, Tesla's sworn enemy. So, in order to make this picture look more mysterious, some fans invented spherical lightning. In order to let the great Mark Twain continue to expose the evil capitalist society without being electrocuted by Tesla, fans do not hesitate to change this critical realist writer's article and let him testify for Tesla, a black technology.

In fact, even in today's laboratory conditions, spherical lightning is difficult to manufacture. It is hard to imagine that Tesla could do it with his own efforts and meager financial resources in that era when there was no foundation for electronic components. What is more exaggerated is that the spherical lightning in the special mouthpiece can be freely played in Tesla's hands without hurting people.
