Nagaoka Hantaro prepared another speech in Tokyo and sent Kimura Sakae to specially invite Li Yu.
Kimura Sakae is a Japanese astronomer who also studied in the UK and later won the medal of the Royal Astronomical Society.
After arriving at Tokyo Imperial University, Li Yu discovered that Nagaoka Hantaro had given himself the title of "visiting professor".
Li Yu didn't refuse too much, he just took it as a matter of course, otherwise it would have a great impact on the Japanese physics academic community and make them make more detours.
There were more people sitting under today's speech. The principal even sat next to him, leaving seat C to an old man about 70 years old.
Nagaoka Hantaro made an introduction: "This is the president of the Imperial Academy, Mr. Kato Hiroyuki."
The Imperial Academy was later the Japanese Academy, equivalent to the highest domestic academic institutions such as the Chinese Academy of Sciences, the British Royal Society, the Prussian Academy of Sciences, and the French Academy of Sciences.
The founder is the famous Yukichi Fukuzawa. Later, Hantaro Nagaoka also became the dean during the war of aggression against China.
The back was crowded with students from Tokyo Imperial University's Faculty of Science, as well as students from the Faculty of Medicine and the Faculty of Engineering.
Li Yu still started with the second law of thermodynamics, then slowly extended to aerodynamics and mechanics, and also mentioned the application of differential equations in physics many times. Finally, he mentioned airships many times, intentionally or unintentionally.
Few people in Japan understand these things, especially sophisticated differential equations, which combine profound mathematics and high-end physics. Currently, only top scientists in Europe are working on them.
Li Yu spoke for three hours. Although he only touched on some superficial topics, the audience still burst into prolonged applause.
Kato Hiroyuki, President of the Imperial Academy, praised: "You are indeed the best scientific giant in East Asia, and you deserve it! Today, Tokyo Imperial University has awarded you the position of visiting professor. I think it is not enough. On behalf of the Imperial Academy, I will give you the title of Duke of Edinburgh." Also given to Mr. Academician.”
The Duke of Edinburgh is an honorary member of the Japanese Academy. Isn’t it true that Japan has been imitating Europe, so it uses this very British title?
The Japanese Academy is different from institutions such as the Royal Society or the Prussian Academy of Sciences. The Japanese Academy mainly evaluates and summarizes research results. As a research institution, it is not particularly strong, so the work is easy and the research pressure is not high. Thesis Naturally less stress.
But the reputation is still quite high, one level higher than that of a visiting professor. After all, for Japanese scholars, becoming an academician of the Japanese Academy of Sciences (a member of the Japanese Academy of Sciences) is an honor second only to those who have received the Japanese Cultural Medal or the Japanese Cultural Merit.
Physics professors like Nagaoka Handaro later also received the Japanese Cultural Medal, but this honor was basically only for Japanese.
The only exception should be Li Mei.
Very surprising! The highest level of the Japanese Cultural Medal, the "First Class Medal of the Rising Sun", was actually awarded to Li Mei after the war. It is simply shocking!
This Li Mei was the one who carried out Li Mei's fire attack during World War II. The fire attack he led caused more damage to the Japanese mainland than the atomic bomb.
The United States bombed Japan many times, but the results were very poor. After Li Mei was transferred to the Pacific Theater, she had a sudden idea: Japanese buildings are all made of wood, so they can be attacked with fire!
Just do it! Li Mei replaced all the bombs on the B29 with napalm, which are high-heat incendiary bombs.
The effect is outstanding! As soon as the napalm bomb appeared, it almost "boiled" the rivers in Tokyo. A large number of Japanese residents were roasted into charcoal. About a quarter of Tokyo's urban area was razed to the ground. Nearly 100,000 people were burned to death, and hundreds of people were burned to death. Thousands of people are homeless.
Two days later, LeMay sent more than 300 B-29 bombers to continue the "fire attack" on Nagoya, followed by Osaka and Kobe... All industrial cities in Japan during World War II were all spared by LeMay's incendiary bombings. The losses are unprecedented.
On May 9, 1945, in order to celebrate the surrender of Germany on the European battlefield, LeMay once again dropped more than 2,000 tons of incendiary bombs on Tokyo, burning 56 square kilometers of land. Tokyo at this time was not very big, and it was called a carpet fire attack. .
The flames over Tokyo could be seen hundreds of kilometers away in the Pacific Ocean.
Half a month later, 500 B-29s bombed Tokyo for the last time. After that, Le Mei never bombed Tokyo again because Tokyo had no targets to bomb.
At this point, Tokyo had been bombed by more than 100,000 tons of bombs, and nearly 60% of the urban area was reduced to scorched earth, making it one of the cities with the heaviest losses in World War II.
In total, more than 500,000 people in Japan were burned to death and more than 8 million people were made homeless because of the Li Mei Fire Attack. This kind of lethality was already more powerful than the two subsequent atomic bombs.
If the offensive can continue for another three or four months, Japan will almost have to surrender.
Li Mei knew this well and went to the Pentagon to propose that he could let Japan surrender. However, the United States was already preparing to use atomic bombs at that time, so he did not care too much about Li Mei's words.
Even former Japanese Prime Minister Konoe Fumimaro once pointed out that the US military's bombing of Tokyo made Japan begin to consider an armistice.
As for LeMay himself, he once said frankly: "Killing Japanese does not disturb me. What disturbs me is the end of the war, so I don't care how many Japanese are killed in our operations."
The Japanese's attitude towards him was rather cynical: in 1964, the Japanese Congress passed a resolution and decided to award Le Mei Japan's highest-level Medal of Honor, the "First Class Medal of the Rising Sun".
In my childhood, I really bullied the weak and feared the strong!
What’s even more funny is that Li Mei didn’t even bother to receive the medal of the fascist camp, preferring to wear the Soviet Union’s Patriotic Medal.
Since Li Mei can win the Japanese Medal, Li Yu has no psychological burden, not to mention it is just a Japanese Academy. Although Li Yu may not make any contribution to Japan in the future, it will still set them back a bit.
Li Yu said to Hiroyuki Kato: "If there is anything that is not done enough, Mr. Kato needs to correct me."
Kato Hiroyuki, who is 70 years old, said: "We should learn from you!"
Several people came to an auditorium and performed a ceremony to confer Li Yu with the title of Duke of Edinburgh.
Also awarded the honor of being a member of the Imperial Academy of Japan is Aiki Tanakadate, who is also an older generation Japanese physicist who engages in geophysical surveying.
Kato Hiroyuki said: "This position cannot be compared with the academician of the Royal Society and the Nobel Prize that you have received. I hope you will not be offended."
Li Yu said with a smile: "There is no distinction between high and low academic positions, the key is academic itself."
Tanakakan Aiki praised: "With such a status, Mr. Academician can still be so humble. He has really learned the essence of Confucian culture."
Anyway, it was a polite statement, so Li Yu casually replied: "Sir, you are overly complimentary."
Tanakadate Aiki added: "Back then, I studied at the University of Glasgow, Scotland, under Lord Kelvin. I recently read some news in the newspaper, and Lord Kelvin's evaluation of you was outrageously high."
Li Yu thought to himself, that's not true. He was the one who saw his first paper. Lord Kelvin had almost witnessed Li Yu's growth in the past few years.
The key point is that Lord Kelvin's status in the physics community is not to mention. Not to mention the British, even the entire European scientific community has to give him face. Even France and Germany on the European continent, which are not at odds with Britain, have to respect and respect Mr. Kelvin now that science has advanced by leaps and bounds.
The respect the little Japanese have for themselves now shows that they recognize the British very much.
After accepting the position of the Imperial Academy of Japan and the position of visiting professor at Tokyo Imperial University, Li Yu wanted to give more lectures at Tokyo Imperial University.
Li Yu still focused his main energy on physics and engineering applications. On the one hand, this was his expertise, and on the other hand, this could play a role in skewing Japan's technological tree.
Li Yu even gave a lecture on the Navier-Stokes equation in class - which is absolutely correct. After all, this equation was also a major research direction in the early twentieth century, whether it was thermodynamics or engineering. There are many people.
Even Einstein often quoted this equation in his papers.
"Water flowing through a pipe, air flowing over an airplane wing, or smoke from a cigar, any fluid you can think of can be solved using the Navier-Stokes equation. It's not just a mathematical problem, it's a fluid problem. There is an unbridgeable gap in mechanics. If you can solve it one day, I dare say you will get a higher honor than me!" Li Yu said on the podium.
Immediately, a student asked: "Taller than you? Does it mean that you can win the Nobel Prize in Physics and the Swedish Mathematics Prize at the same time?"
Li Yu nodded: "Without a doubt."
"But the mathematics involved in this equation are really maddening. I don't think even Amaterasu can solve it." One student said.
Li Yu said with a smile: "If you study more and offer more sacrifices to Amaterasu, maybe Amaterasu will give you some wonderful ideas."
Encouragement is definitely needed.
However, Li Yu's mere mention that solving it would lead to the highest award was enough to drive these students crazy. Even Japan’s highest cultural award cannot be compared with the Nobel Prize.
"Is this simple equation really so magical?" The student was still a little confused.
Li Yu explained: "Any modern ships, warships, submarines, as well as cars that are now considered luxury goods, and higher-end aircraft are all inseparable from this equation. Even in medicine, its value is incomparable."
"Does medicine have something to do with it?"
"Of course," Li Yu continued, "the medical research on venous and arterial blood flow is still essentially the category of fluid mechanics."
"Oh my God!" Many students were completely convinced. They had never been exposed to such high-end knowledge before. Warships, submarines, and automobiles and airships simply opened a new door.
But they certainly don’t know that immersing themselves in this research direction is almost locking up the possibility of future breakthroughs.
Just like asking a student to solve Fermat's last theorem and Poincaré's conjecture at this time, or suddenly realizing that there are quarks in the nucleus, and there are two other forces in physics - it is simply impossible. This is the development of science. limits.
In other words, Li Yu set a trap for them, a trap that they really wanted to get into, and once they got in, there was almost no possibility of getting out.
It's not a matter of genius or not. Everyone who can do mathematics is a genius, because mathematics is completely based on IQ. No matter how hard a student works, if he does not have a strong talent, he will not make any real breakthrough in mathematics. At most, he will have to change his career to other directions.
Over the past 100 years, have there been still few geniuses born in the world of mathematics?
The Navier-Stokes equation cannot be solved, and Li Yu cannot make any comments, because before he traveled through time, this thing was also one of the seven major problems of the millennium and remained unresolved.
But it can be compared to the solved Poincaré conjecture, or Fermat's last theorem, and Goldbach's conjecture, which has only "the last small step" left.
To borrow the words of a great mathematician: These difficult problems require the emergence of other new mathematical tools, otherwise there is no possibility of solving them.
Li Yu now poses big problems such as the Navier-Stokes equations to these students. In the future, these students will have some small breakthroughs. For example, Japanese mathematicians also played a role in the solution of Fermat's last theorem. But in the end, I still made wedding clothes for others.
Now when it comes to Fermat's Last Theorem, everyone only remembers Wiles. How many people know that the Japanese Yutaka Taniyama and Goro Shimura also contributed to his process? How many people know the significance of the Taniyama-Shimura conjecture to Fermat's last theorem?
It can be said that most of the students who listened to Li Yu's lecture will move forward on an absolutely correct and extremely broad road, but they will never see hope.
For Li Yu, this is also a kind of screening. It is inevitable that some people will jump out, and then they will continue to guide them to the airship.
It's double insurance.
Li Yu's reputation is now so great in the entire East Asian academic circle. His lectures are packed with people every day, and even several professors from the Faculty of Science at Tokyo Imperial University, including Hantaro Nagaoka, Aiki Tanakadate, and Eiji Kimura, all come to listen. , and Kotaro Honda, who later became a great metallurgist in Japan.
Li Yu is not good at giving lectures in primary and secondary schools, and his university lectures are also average, but he treats university lectures as a kind of TED talk.
This thing can be freely used, and you can brag a little bit. Anyway, you know the future better than anyone else. Li Yu also made some predictions:
"In the future, the two dark clouds of science will dissipate, and what will appear behind will be a broader world. What you will see the fastest will be the theory of relativity illuminating half of the sky of physics."
Tanakadate Aiju said: "Academician is referring to the two dark clouds mentioned by Lord Kelvin? That is a big problem that has shrouded the entire physics for ten years and still has no clue."
Li Yu said: "It is about the dark cloud about the ether and the constant speed of light. It is a pity that the German magazine has not been translated yet, otherwise I can explain it to you on the spot."
In terms of understanding of the theory of relativity, Li Yu is definitely second only to Einstein in this era, and he is not bragging at all. Maybe in the future when Edinburgh says that there are only three people in the world who understand the theory of relativity, they will have to consider Li Yu and make it four.
As for the theory of relativity, Li Yu is not afraid of the Japanese studying it, because the theory of relativity is definitely a nightmare for experimental physicists, and there is almost no possibility of experimental measurement. The nickname of the theory of relativity is "the paradise of theoretical physicists and the nightmare of experimental physicists".
