Morgan agreed to invest another $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
"I have the feeling that others don't have", it doesn't matter if I spend more money or the price/performance ratio is lower. 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 then create artificial lightning." Li Yu said: "I remember the architect said that this project is It will cost 200,000 US dollars." Tesla said: "That's right. I thought Mr. Morgan would only give 150,000 US dollars, and now it's enough." Li Yu felt a big headache. Tesla was very interested in wireless power transmission. Really obsessed.
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, 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: "A few of my engineers will help throughout the process, and I will learn a little by the way." Tesla said: "I know, I will help you teach. But you must keep the direction of my funds secret." Li Yu didn't know Whatever he said, he had no choice but to agree: "I'm afraid the paper can't contain the fire." Tesla said confidently: "This is my last chance, and I won't let it go." Having said this, Li Yu couldn't persuade him anymore.
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 "sce" magazine he invested in was also going to publish a new issue. As promised in advance, he had to continue writing articles.
Things need to have ups and downs, and Li Yu plans to write something less sensational this time. After all, the sales of the first issue were so good that it is still being printed, 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 plans to write another article on astrophysics.
His "Fractals and Chaos" made many people start discussing the multi-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, one or more comets entered the Roche limit of Saturn, and were then torn apart by tidal forces to form the rings of Saturn.
Roche Limit was also a popular concept before Li Yu's time travel because of "The Wandering Earth". But there is 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 that it cannot tear the earth into pieces.
Although the fluid Roche limit reaches a radius of 110,000 kilometers, it exceeds 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 was that the director team was careless and 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 a distance of 1.71 million kilometers from the sun. Rather than the Roche limit distance between Jupiter and Earth.
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? You 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 theory 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, he has to do something every time he writes a paper.
He also mentioned that according to theoretical derivation, the rotation speed of the earth is also slowed down very very slowly by the tidal force of the moon. One day in the future, the earth and the moon may be tidally locked with each other, that is, the two planets are like two people. It's like pulling the hands together in a circle.
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 has to write an article to introduce his
"Mobile radio receiving device", also known as radio, talks about the great role of triode in communication in principle.
This article was not only submitted to "SCE", but also handed over to Pulitzer's "Le Monde" for publication. However, "Le Monde" deleted the technical part, leaving only the simplest principles and practical application content. .
Many elders were indeed very interested. The first person to find Li Yu was 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 his Standard Oil headquarters 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. The location is very good, right on the Upper East Side next to Central Park in Manhattan. Rich 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 rarely had contact with Rockefeller. Before that, he mainly had dealings with Morgan.
"Two great scientists, this university really complements each other with your arrival." Rockefeller said,
"I heard that you have developed an excellent radio device again. An old man like me really wants to see such a thing." Li Yu and Tesla showed him the radio set, and then said: "The current radio operation The cost is still relatively high, and I think there will be a dedicated broadcasting company in the future." After the sound came from the radio, Rockefeller and Morgan reacted equally excitedly,
"Something new! Fascinating!" This time there are more sound sources than last time, and there are even songs.
Rockefeller was obviously more concerned with 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 US dollars per unit." This is almost a sky-high price, close to a Cadillac sedan.
Unexpectedly, Rockefeller readily agreed: "Yes, but the delivery speed 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 cannot be mass-produced. By then, I think its price may only be a few dozen dollars." Rockefeller laughed: "No wonder I heard Morgan say you are a weirdo, you really don't know how to do it. Do business! Of course I know its price will drop 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 settled," Rockefeller said, standing up.
"Anyway, I came here and just took a walk in the institute." Rockefeller University is very small. It has only recruited doctoral students and focused on biology and medicine.
The campus is very compact, and those who didn’t know it would have thought it was a middle school. Rockefeller said to Li Yu: "I happen to have a very good Oriental scholar here, but he is a 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 also intend for him to enter Rockefeller University after graduation."
