Who is Tesla?
Nikola Tesla
An inventive genius who can describe all the details perfectly in his mind without any models, drawings and experiments, and is no different from the actual object.
He is Edison's most powerful opponent, and he is also a scientific madman who has independently developed and obtained 700 kinds of patents all his life, and cooperated in research and development of more than 1000 kinds.
Yes, Tesla is not only a brand of high-end electric vehicles, but also a physical unit: 1 Tesla = 10000 gauss, and it is also a name worth remembering.
The following is a video specially produced by "Ghost Story of Old Pipe" to commemorate the birth of nikola tesla. Friends who don't have wifi can skip reading the article directly, but the video is more enjoyable.
Let's look at the video introduction-
Pioneer of the electrical age
When you are lying on the sofa watching TV with the lights on and blowing air conditioning, have you ever thought about how the electricity that supports these household appliances comes from?
100 years ago, when most people were still using candles for lighting, an electric power system called alternating current was invented and has been in use ever since.
Its inventor is nikola tesla. His alternating current brought mankind into the second industrial revolution.
If you ask, isn't Edison the "father of the electrical age"?
Then the next story will give you a new understanding.
1884 a young man took a letter of introduction from his former employer and hurriedly boarded a ship bound for the gold rush in the United States. He is going to find his idol Thomas Edison, hoping that he can help him complete the invention of AC system.
Thomas Edison
The letter wrote:
"Dear Edison: I know two great men, one is you and the other is this young man."
At that time, Edison was selling his DC system to the whole world. He didn't like AC at all. But with this letter, Tesla entered Edison's team as he wished. Edison promised that if he solved the "problem of DC generators and motors", he would get a prize equivalent to $1 million today.
But when Tesla repaired Edison's machine, he asked, "What about the promised 1 million?"
Edison actually smiled. He said, "Tesla, you don't understand our American humor."
The idol in my heart collapsed, and the teased Tesla angrily left and became an independent portal. From then on, he devoted himself to his AC system.

At that time, Edison's DC system required a power station per square mile, and the transmission distance was very limited because of the excessive loss during transmission, while Tesla's AC system used thinner wires, higher voltage, less transmission loss and longer transmission distance. Obviously, alternating current has advantages.
What did Edison do at a disadvantage?
Edison's brain opened the door to "black" alternating current. Bribing * * * officials, changing the death penalty from hanging to electrocution.

Even hiring primary school students to electrocute stray cats and dogs with alternating current to promote that alternating current is "very dangerous".
Fortunately, Tesla firmly believes that "you are black or not, alternating current is there", and demonstrates the reliability and safety of alternating current through the lighting project of the Gebo Fair, and finally wins the "current war" and also clears himself.

Since then, alternating current has been recognized, replacing direct current and becoming the mainstream of power supply.
You know, at that time, every time Tesla used a piece of electricity, people could get a patent fee of $2.5. According to statistics, this will bring at least $300 billion to Tesla! Tesla will be as rich as the enemy.
Unexpectedly, he tore up the patent contract and provided the invention to the world for free. If he hasn't done so, we have to pay him now.
Therefore, it is well-deserved to call Tesla "the father of the electrical age".
Someone who will make you question the Nobel Prize.
Who discovered x-rays?
Wilhelm konrad rontgen?
Don't! be
According to historical records, Roentgen discovered X-rays on1895165438+10, paving the way for medical imaging technology, and was awarded the first Nobel Prize in Physics in190/kloc-0.
But in fact, Tesla discovered X-rays before Roentgen and warned it was dangerous and refused to conduct medical experiments.
Tesla used his body to test X-rays.
This is an image of his foot.
Who invented radio?
Guillermo Marconi?
Don't! be
Up to now, many people think Marconi is the inventor of radio. He won the Nobel Prize in Physics from 65438 to 0909 and was called "the father of radio".
But in fact, Tesla has obtained the patent of radio technology of 1897. It was under Edison's intervention that the US Patent Office revoked Tesla's patent right and granted it to Marconi instead.
1943, the US Supreme Court re-recognized nikola tesla's patent and declared Marconi's radio patent invalid.
On Tesla's 75th birthday, * * * received letters of thanks from eight Nobel Prize winners in physics.
1943, Tesla's funeral was also attended by three Nobel Prize winners on behalf of the Nobel team. Over the years, the Nobel Prize winners in physics have always expressed their gratitude and respect to nikola tesla.
It is said that 27% of the people who studied Tesla's invention were directly inspired and won the Nobel Prize in Physics, and more than 65% were inspired indirectly.
Tesla himself, 1 1, was nominated for the Nobel Prize for 9 times and was rejected for 2 times.
Every prediction he made,
Can make the world fast forward at least 100 years.
In Current Wars, Tesla once said: "Alternating current is the future trend". A hundred years later, the alternating current he invented still illuminates the whole world.
In an experiment, he heard a strange and rhythmic sound coming from the receiver. At that time, he believed that human beings could receive information from another world. 1899, he discovered cosmic radio waves, which were not confirmed by scientists until 1932. Today, we can also receive the signal received by Tesla through the radio telescope.
FAST radio telescope is called "500-meter spherical radio telescope (FAST)".
In addition, "remote automation" was also invented by Tesla. Our futuristic unmanned driving, which has just become popular recently, can be done more than 100 years ago.

Even the "wireless charging technology" of some mobile phones is actually Tesla's afterplay.

Tesla coil is the most advanced and controversial invention in Tesla's life, and it is also his greatest contribution to mankind. Because this is a free energy technology, it can be supplied without electricity.
100 years later, when we hear "free energy", "inexhaustible electricity" or "free electricity", we will still think that it is a fable. But more than 100 years ago, Tesla coil can already do this.

Such a master of science,
Why don't we know?
Tesla has more than 1000 invention patents. The scientific invention system in today's world is still based on the legacy left by Tesla.
But the invention we can recognize and adopt now is only his invention before he was 40 years old. All his inventions after the age of 40 were banned.
It is said that Tesla was still doing research on super particle weapons before his death, and put forward the concept of "beam weapon". But it was not until March 1983 that President Reagan put forward the "Star Wars Plan". In order to deal with the devastating nuclear threat, Tesla's concept of beam weapon finally got the attention of the United States.
Tesla described this in his manuscript-his own special particle emitter can generate huge energy at the end. Simply put, they can be used as excellent prevention and control equipment, which can easily and quickly land or even destroy 10000 enemy planes 200 miles away!
From his own description, you can easily know how powerful this weapon is. Unfortunately, however, due to the lack of supporters and certain basic materials, some things can only be shelved, and finally there is no progress until Tesla dies!
If this technology has been studied since then and reached the cutting-edge level, do you dare to say that nuclear weapons are the absolute hegemon of the weapons industry?
After Tesla's death, the Ministry of War contacted the FBI, who confiscated all his design drawings and experimental works and classified them as top secrets. The us military has not stopped studying his paper so far.
A document records: "(He) has 80 suitcases, distributed in different places, which contain his research manuscripts and experimental plans ..."
Of course, Tesla was forgotten for other reasons besides * * * "blocking":
Tesla is a man beyond his time. He sees too far and his invention is too advanced. At that time, he was often regarded as a scientific heresy, even a Martian.
Tesla keeps a diary under ultra-high voltage artificial lightning.
It's one thing to make great inventions, and it's another to get people to admit it. At that time, there were too few people with foresight and too low tolerance for innovation.
However, what has been forgotten by the world about this great scientist who was nominated for the Nobel Prize for 1 1 times, made way for him for 9 times and refused to receive it for 2 times?
As he famously said under the bronze statue of Tesla in Silicon Valley: "The present is theirs, and the future I am committed to is mine."
