Morgan agreed to inject a further $200,000, but first provided him with five radio receiving devices.
The boundaries between factories, enterprises, and workshops today are far less clear than in later generations. Of course, in later generations, the distinction was often not very clear either.
Buyers can place orders to companies or individuals; sellers can also take advantage of this to continue research and development.
At the beginning of the twentieth century, almost all disciplines were rapidly evolving in this way.
Anyway, what rich people want is freshness and the feeling of "I have something that others don't have". It doesn't matter if you spend more money or it's less cost-effective.
After all, the productivity of the United States has increased so rapidly that its social consumption capacity is almost as high as that of the entire Europe.
Tesla now had money, and he immediately began to think: "Great, with the money, I can complete the power improvement project and create artificial lightning."
Li Yu said: "I remember the architect said this project would cost US$200,000."
Tesla said: "That's right. I thought Mr. Morgan would only give $150,000, but now it's enough."
Li Yu felt that his head was very big. Tesla was really obsessed with wireless power transmission.
There is really no other way. It seems that he will not look back until he hits the wall.
Forget it, let him suffer enough losses, otherwise he will always keep this in mind.
It's just that Morgan will definitely be angry to death by then, and then he will definitely give up his money on Tesla as he did in history, and instead invest his money in the Italian Marconi.
Li Yu reminded him: "No matter what, we must first make a few stable versions of radios."
"I know, it's for Mr. Morgan," Tesla said casually.
Li Yu said: "Several of my engineers will assist throughout the process, and we will learn from it by the way."
Tesla said: "I know, I will help you with the church. But you must keep the direction of my funds secret."
Li Yu didn't know what to say, so he had to agree: "I'm afraid the paper can't contain the fire."
Tesla was very ambitious: "This is my last chance, and I won't let it go."
Having said this, Li Yu could no longer persuade him.
Li Yu sent three engineers, Zou Zhou and others to manufacture radios at Tesla's place, and learned as much as possible the basic manufacturing steps.
On the other hand, the "Science" magazine he invested in was also going to publish a new issue, and as promised in advance, he had to continue writing articles.
Things need to have their ups and downs, so Li Yu plans to write something less sensational this time.
After all, the sales of the first issue were so good that they are still printing more copies, which is unbelievable.
Thanks to their reputation, more researchers submitted articles for the second issue.
In view of the current love of astronomy among American scientists, Li Yu is planning to write another article on astrophysics.
His "Fractals and Chaos" made many people start discussing the many-body problem again, but it was obvious that the three-body problem was too difficult, so Li Yu planned to write a conventional two-body problem.
In the article, he first discussed the Roche limit, which Roche had studied decades ago, and the analysis of the causes of the formation of Saturn's rings.
To put it simply, a certain comet or a few comets entered the Roche limit of Saturn, and were then torn apart by tidal forces to form the rings of Saturn.
The Roche limit was also a popular concept before Li Yu's time travel because of "The Wandering Earth". However, there was a small bug in the movie: the director actually gave the wrong Roche limit distance between Jupiter and the Earth.
According to calculations, because Jupiter's density is too small, its rigid body Roche limit is within itself, which means it cannot tear the earth into pieces.
Although the fluid Roche limit reaches a radius of 110,000 kilometers, exceeding its radius of 70,000 kilometers. However, this value is quite small. With such a close distance, it is not as simple as tidal force, because the mass of the earth is not small.
The rigid Roche limit between Jupiter and the Earth given in the movie is 890,000 kilometers, and the fluid Roche limit is 1.71 million kilometers. The story is mainly developed to avoid entering the rigid Roche limit.
The reason for the mistake is that the director team was careless. They included the Roche limit data of the sun and Jupiter. That is, the distance at which Jupiter will be torn apart by the sun when it enters 1.71 million kilometers from the sun. Instead of the Roche limit data of Jupiter and the earth.
extreme distance.
However, this small bug does not affect the excellence of the movie itself.
——This is the bad habit of men in science and engineering.
Haha, it’s hard to find such a good movie, and it’s a hard science fiction movie. I have to find faults with others, find faults in others, and destroy the things I like with my own hands.
Well, what's the saying?
Deserve to be single...
Going back to Li Yu's article, after discussing the formation of Saturn's rings through the Roche limit, he also mentioned that Jupiter also has planetary rings, but they are not easy to observe.
Then we talked about tidal locking.
——There is currently no complete scientific theoretical study to understand why the recent moon has always had only one side facing the earth.
The formation of tides has been studied to some extent by previous people. Li Yu extended it and then discussed through mathematical calculations and force analysis that the moon has been tidally locked by the earth, so only one side faces the earth.
According to analysis, the moon is an oblate spheroid, with its long axis always pointing toward the earth.
Finally, according to Li Yu’s characteristic of having to do something every time he writes a paper, he also mentioned that according to theoretical derivation, the earth’s rotation speed is also very, very slowed down by the moon’s tidal force. One day in the future, the earth may and
The moons will be tidally locked with each other, that is, the two planets will be like two people holding each other in a circle with their hands.
But this time will be very far away, and even the day when the sun explodes will not come.
So at the end of the article, he added a Chinese saying that was a bit off-key: When that day comes, the mountains will have no edges and the heaven and the earth will be united.
Anyway, foreigners like Chinese calligraphy very much, but Li Yu’s level of writing Chinese characters is a bit low, so he can only fool foreigners.
In addition, he naturally had to write an article to introduce his "mobile radio radio device", that is, a radio. In principle, he talked about the great role of triodes in communication.
This article was not only submitted to "Science", but also to Pulitzer's "Le Monde" for publication. However, "Le Monde" deleted the technical part, leaving only the simplest principles and practical application content.

Many big guys are indeed very interested.
The first person to find Li Yu was surprisingly another American super chaebol, the oil king Rockefeller.
Rockefeller is also the kind of person who has more time, because he retired a few years ago, but he still holds a lot of equity and no longer has to worry about daily management.
Rockefeller moved the headquarters of his Standard Oil Company to New York many years ago, and after the University of Chicago, he donated money to build a new university two years ago - Rockefeller University (currently called the Rockefeller Institute of Medical Research). The location is very good.
On the Upper East Side next to Central Park in Manhattan, a wealthy area of New York.
Rockefeller was a man who loved investing in education and would spend even more money on it than Carnegie.
Li Yu and Tesla were invited to Rockefeller University on the Upper East Side of Manhattan.
Like Carnegie, Rockefeller has lost a lot of airs since he stepped down from his management position. Meeting him and meeting Morgan are completely different feelings.
Rockefeller chose to meet at a university to demonstrate his passion for education.
"Hello Mr. Rockefeller!"
Tesla also had little contact with Rockefeller. Previously, he mainly had dealings with Morgan.
"Two great scientists, having you here at this university really complements each other." Rockefeller said, "I heard that you have developed an excellent wireless device. An old man like me really wants to see such a thing.
"
Li Yu and Tesla showed him the radio, and then said: "The operating cost of radio stations is still relatively high now. I think there will be specialized broadcasting companies in the future."
After the sound came from the radio, Rockefeller and Morgan reacted with excitement, "Novelty! Fascinating!"
This time there are more sound sources than last time, and there are even songs.
Rockefeller was obviously more concerned about its role in transmitting information. "It doesn't matter if the cost is higher. I can buy 3 units. What's the price?"
Tesla said: "The current price will be relatively high, $600 per unit."
This is almost a sky-high price, close to a Cadillac sedan.
Unexpectedly, Rockefeller readily agreed: "Yes, but the delivery must be fast."
Tesla continued: "Actually, Mr. Rockefeller, I think its price will come down in less than half a year. But now our production capacity is still relatively weak and we cannot mass produce it on a large scale. By then, I think it will
The price may be only a few dozen dollars.”
Rockefeller laughed loudly: "No wonder I heard Morgan say that you are a weirdo, you really don't know how to do business! Of course I know that its price will decrease in the future, but what if I don't want to wait half a year?"
Tesla understood what Rockefeller meant and said, "Okay, Mr. Rockefeller, I will do it for you as soon as possible."
He was also worried, and he had to prepare the radio again, delaying his trip to Wardenclyffe Tower for experiments.
This is just Rockefeller. You don't have to think about it to know that in the future, many Wall Street plutocrats and bankers may also need it.
"That's it," Rockefeller said, standing up. "Here we are, just taking a walk in the institute."
The Rockefeller University is very small. It has always only admitted doctoral students, and it focuses on biology and medicine. The campus is very small, and those who don’t know it might think it is a middle school.
Rockefeller said to Li Yu: "I happen to have a very good Oriental scholar here, but he is Japanese."
Rockefeller took them to a biological laboratory, then pointed to a young Japanese and said: "This is Hideyo Noguchi. He is currently studying at the University of Pennsylvania. His report on snake venom four years ago was extremely amazing. I am also interested."
Let him enter Rockefeller University after graduation."
