"A lot of people don't believe it, do they?" Lin Dong said with a smile: "I think that sometimes the things in the textbook may not be completely correct, or they may not explain the history of a certain field. Like Nikolai? Tesla. ”

"I think a lot of people will question, so here, to Nikolai? I won't go into so much detail about Tesla's life, and you will definitely search on the Internet when you go back. I'm just going to touch on the history of his invention. ”

"Nikolai? Tesla, a native of Austria-Hungary, now known as Croatia, went to university and designed the first model of an induction motor in 1882 when he was in the Paris branch of the Edison Telephone Company. In 1884, he landed on American soil and came to New York, where he joined Edison's room. He was holding a letter from his former employer to Edison, which read: I know two great people, one is you and the other is this young man. This young man, in this case, is Nikolai? Tesla. ”

Just these few words made the students in the auditorium feel the extraordinaryness of the person Lin Dong was talking about. Some students had already turned on their mobile phones and started searching, while more continued to listen carefully to Lin Dong's speech.

In Edison's room, Tesla soon took charge of the electrical design and was fully responsible for the redesign of the company's DC motors. In this respect, he surpassed Edison's talent. In 1886, Nikolai? Tesla set up its own company, and in 1891, completed the design of Tesla's coil and applied for a patent, but unfortunately, now everyone only remembers his patent. ”

Low laughter spread through the auditorium, and some of the students had a faint look of shame on their faces.

"What I'm going to talk about next, Nikolai? One of Tesla's most famous inventions. With a strong memory and an encyclopedia in his brain, Lin Dong talked eloquently: "In 1891, after Tesla successfully experimented with sending electricity to the target electrical appliances in the form of wireless energy transmission, it began to devote itself to the commercialization of intercontinental wireless transmission of electricity, and built the Worden Crevert Tower with this as an idea. Below. I'll say directly about his achievements:

In the spring of 1893, Tesla made 1 million volts of high-voltage electricity out of a conical coil, and in May of the same year, he demonstrated alternating current lighting at the Columbia Exposition, becoming the winner of the battle for currents, which is the direct reason why we have been using alternating current instead of direct current; In 1898, Tesla registered wireless control technology. In New York's Central Park carried out a remote control automated boat for everyone to know that this was more than a hundred years ago. Think about wireless technology! ”

When the students were surprised, Lin Dong continued: "In the same year, Tesla used a small electromechanical oscillator to create a small earthquake; In the winter, he exhibited the machine qì man automatic boat, and in 1899-1900, Tesla created ball lightning, and in the same year the first artificial lightning was achieved in the world, in 1906. He invented the bladeless turbine, in 1928 he patented an air transport device, and in 1931 he proposed a plan to extract energy from nature: geothermal steam and seawater power generation are both currently in use. In 1935, he invented dead light, which is a beam of charged particles. It was in 1943, after his death. The United States decided that the inventor of the radio was not Marconi, but Tesla. ”

Speaking of this, Lin Dong paused before continuing: "Based on the above, Tesla's research field. Including alternating current systems, radio systems, wireless power transmission, ball lightning, turbines, amplification transmitters, particle beam weapons, electro-positive energy generators, optical equipment, electrical energy meters, missile science, remote sensing technology, aircraft, cosmic rays, radar systems, and machine ...... He is not only researching, he has almost all the results in these fields! ”

Speaking of this, Lin Dong continued to say loudly as if to confirm that "the language is not amazing", and continued to say loudly: "In addition to the more than 700 inventions in the field I just mentioned, Tesla is also a poet, philosopher, music connoisseur, pigeon expert, linguist, Vedic expert, he is fluent in eight languages: Serbian, English, Czech, German, French, Hungarian, Italian and Latin. He only sleeps 2 hours a day. and never married......"

The auditorium fell silent again.

After a long time, the female student who asked the question just now asked faintly: "Since he is so famous, why don't many people know about it?" ”

Lin Dong shook his head slightly: "I can't give you a clear answer. Maybe it's because he pays too much attention to research and never considers the application and promotion of these patents, or maybe as many people say, he was suppressed by Edison and Morgan and others, or his invention was too advanced, such as the wireless power transmission just mentioned, there are still many people researching, but the level of research is better than Nikolai? Tesla's research is far worse, a variety of reasons, which one is specific, you need to feel it specifically, I don't want to mislead you. ”

Many people listened to Lin Dong's words, and secretly decided to check Nikolai when they went back? Tesla this person.

But at this time, the girl spoke again, attracting everyone's attention:

"You've talked so much about Tesla, I want to ask, does that have anything to do with the question I just asked you?"

Lin Dong smiled, his crooked building finally let her help her back.

"Of course it does. The reason why I say Tesla is that I am very interested in his experience and I admire this person very much, and secondly, I mean that success does not mean that you have to study in your own field, but you can also be in different fields, as long as you are interested. He invented more than 700 patents in his lifetime, and I didn't actually ask for that much, I just needed to study more in the areas I felt interested in. ”

Speaking of this, Lin Dong sighed: "In fact, when I was researching the games that match the virtual helmet, I also tried to retreat for a month and sleep less every day, but I can't sleep two novels a day like him." To be honest, for those of us who still fall asleep even if we sleep eight hours a day, sleeping for five or six hours and then spending the rest of the time studying is already the extreme! ”

"Hahahaha......" Lin Dong's sentence of us, coupled with the topic of sleeping, further narrowed the distance with classmates, many people deeply sympathize, getting up every morning, it is really a very painful thing!

"So, although I already have a few inventions and technologies, and I have a little bit of success, compared to them, I am only a little more successful than ordinary people, and there is still a lot to work on!" (To be continued.) For mobile phone users, please visit wènhttp://mnet
