Chapter 144 Physics in the Early Years of the Neon Country
King Gong and the others naturally wanted to stay longer in Yokohama, and soon Tokyo Imperial University received news that they already knew that Li Yu had arrived in Yokohama.
Yokohama is very close to Tokyo, and Japan's first railway was also built between Yokohama and Tokyo.
Hantaro Nagaoka, a physics professor at Tokyo Imperial University, and Masataka Ogawa, a chemist who is the acting president of Tohoku University, actually came to find him personally.
Takeshi Inukai and Utako Shimoda are also celebrities in Japan, so they found Yokohama Daido School without much effort.
However, Li Yu didn't know them, and indeed they were not important figures in the history of physics or science.
The guard whispered a few words into Inukai Yi's ear, and Inukai Yi raised his eyebrows: "Professor of Tokyo Imperial University!?"
The guard said: "Yes, they have arrived at the door."
Although Nagaoka Hantaro and Ogawa Masataka are not prominent politicians, Tokyo Imperial University is now the highest university in Japan. Everyone also deeply understands the importance of education and scientific research to national strength, and everyone from top to bottom respects the professors of Tokyo University.
.
Inukai Yi did not dare to neglect, and hurriedly greeted him: "Why did the two professors visit my elementary school?"
Hantaro Nagaoka got straight to the point and said, "Excuse me, has a Chinese named Li Yu arrived at your office?"
Inukai Yi nodded: "Yes, this person is visiting our school."
"Then we are in the right place! Great!" Ogawa Masataka said happily, "Please take us to meet Mr. Li Yu. We have admired his name for a long time and can't wait to see him in person."
Although Inukai Takeshi was still a little confused, could an imperial master be so powerful? However, the other party was an important professor after all, so he had no choice but to do as he was told: "You two, please follow me."
Inukai Takeshi pointed forward: "That one is him. He has just been in Yokohama for more than half a day. I didn't expect you to get the news."
Hantaro Nagaoka said: "To be precise, we knew it from the moment he stepped on the train to Yokohama. We thought he was coming directly to Tokyo, but unexpectedly he got off the train in Yokohama on the way. We couldn't wait any longer, so we rushed over.
."
Inukai Yi opened his mouth and was speechless. He didn't expect that Li Yu's energy was beyond imagination.
Although he does not understand mathematical sciences, Nagaoka Hantaro and Ogawa Masataka are both people in the scientific research circle. They exploded on the spot after seeing Li Yu's paper earlier. They know very well what level of existence Li Yu is.
Hantaro Nagaoka stepped forward quickly: "Are you Mr. Li Yu?"
Li Yu knew Japanese, but Hantaro Nagaoka was older than him, so he even used honorifics when he came up.
Li Yu replied: "I am Li Yu, I wonder who you are?"
Hantaro Nagaoka immediately introduced himself: "I am Hantaro Nagaoka, professor of physics at Tokyo Imperial University. I sent a telegram to the Qing Dynasty before. Did you receive it, sir?"
Li Yu said: "It turns out to be Professor Nagaoka. I'm disrespectful. I received the telegram and was about to go to Tokyo University to visit the professor."
Hantaro Nagaoka said: "You are now the star of science in the entire East. It is our honor to be able to come to Tokyo."
Hantaro Nagaoka is Japan's first physics professor and can be regarded as an early pioneer of Japanese physics.
Masataka Ogawa also said: "Although Japan does not currently have all of your complete papers, we have already read your papers on rays, thermodynamics and new planets; by the way, there is also the recently published "Fractals and Chaos"
."
Li Yu was surprised: "The two professors have seen so much."
Hantaro Nagaoka smiled and said: "There are not many people engaged in scientific research nowadays who have not read Mr.'s thesis."
Ogawa Masataka suddenly came back to his senses: "You can actually speak Japanese! This is better. We are still thinking about how to let your husband give a lecture at Tokyo Imperial University. It is really difficult to find a translator who understands the professional field."
"Do you still want to give a speech?" Li Yu asked.
Hantaro Nagaoka said: "Yes, it is difficult to find a gentleman, and he is also a person who understands the most profound science. It is really rare."
"Okay." Li Yu really couldn't refuse.
Hantaro Nagaoka is still gushing: "When I first entered the University of Tokyo to study mathematical sciences, I was confused when faced with choosing a major. I doubted whether Orientals could learn science well and whether they would be able to produce results in the future. For this reason, I even took a break from school to think about it.
, I consulted a large number of Chinese classics and found that the Chinese had long ago invented things such as the compass and gunpowder, discovered the aurora, and measured the movement of celestial bodies, so I established my confidence to continue studying science."
Previously, Japan was also a scientific desert, and people like He Yujie, a distinguished figure in the Department of Physics of Peking University, were crossing the river by feeling the stones.
Li Yu said: "The professor's perspective and method of looking at history are worth learning from."
Hantaro Nagaoka continued: "For hundreds of years, white people have been the strongest in science. But I have always believed that there is no reason for white people to be ahead of us in every aspect! I hope to defeat those white people in 10 or 20 years. And you
You did it early and did it so well! We are really impressed!”
Li Yu smiled and said: "I also agree with what you said, white people can't be stronger than us in every aspect."
On the side, Takeshi Inukai found that the dignified professor of Tokyo Imperial University and Li Yu were having a lively chat. It seemed that he was definitely a real scholar and not a fake.
He asked Ogawa Masataka in a low voice: "Is Li Yu really that powerful?"
Masataka Ogawa said: "In terms of science, especially mathematics and physics, he can be said to be the best now."
Inukai Yi was shocked: "There is such a person in the Qing Dynasty. What is his educational background?"
Ogawa Masataka shook his head: "We don't know anything about his past. We only know that his achievements are very magnificent. Isn't this enough?"
Inukai Yi nodded thoughtfully: "That's enough."
Nagaoka Hantaro turned to Inukai Takeshi and said: "If you don't mind, Mr. Congressman, we would like to invite Mr. Li Yu to Tokyo Imperial University now."
Inukai Yi said: "Of course there is no problem, as long as Li Yu agrees."
King Gong and others have to stay in Datong School for one day for the time being, and they don't understand science, and they don't have much interest in it, so they are in no hurry to leave Yokohama.
Li Yu was also very kind and could not refuse. King Gong and others would also follow him to Tokyo, so he had to agree to take the first step.
On the train, Hantaro Nagaoka talked about his scientific research direction again: "I am also a staunch supporter of atomic theory, but I have never been able to find someone to talk to. I am so excited to meet you today.
I have always had an idea about the atomic model in my mind, which is different from the 'jujube cake model' proposed by Professor Thomson, so I would like to discuss it with my husband."
Li Yu said: "Professor, please give a lecture."
Hantaro Nagaoka took out a stack of paper from his bag: "This is the result of my research during this period. I imagine that the microscopic model of atoms should be similar to the structure of Saturn and its satellites."
"Huh?" Li Yu picked up the piece of paper. There was a huge atomic nucleus drawn in the middle, and then there were small extranuclear electrons around it. It was indeed like the structure of Saturn and its satellites.
Hantaro Nagaoka asked with some anticipation: "What do you think, sir?"
Li Yu said: "It is indeed more advanced than the jujube cake model. How did you make this conjecture?"
Hantaro Nagaoka said: "Actually, I also relied on intuition and guesswork."
Li Yu sighed in his heart. Although it seems that Nagaoka Hantaro's "Saturn Model" is similar to Rutherford's "Planet Model" a few years later, physicists have very vicious views: One is that Saturn has satellites
, one is the sun with the planets. It is very different in nature.
Rutherford's dare to propose the "planetary model" has a foundation: that is, the famous alpha particle scattering experiment. It was through this experiment that Rutherford knew that most of the atomic nucleus is empty, and the volume of the atomic nucleus should be very large.
Small.
That's why he proposed a "planetary model" similar to the entire solar system, because the solar system is also very empty, and the mass of the sun is extremely large.
But Hantaro Nagaoka's model is too much like a guess: the system composed of Saturn and its satellites does not have such a large open space at all. If Nagaoka had also done alpha particle scattering experiments, he would definitely not have proposed this model.
But after all, it was better than the jujube cake model, so Li Yu had no choice but to say: "You can try to publish it."
Nagaoka sighed sincerely: "I have sent it to many Western scientific magazines, but no institution is interested. Japan now has little say in the scientific community, and there is no place to even express an opinion. That's why I
I'm shocked that your achievements can actually make those white masters and the Royal Academy of Sciences treat you with great courtesy."
"It's really not easy." Li Yu said.
He was able to achieve this kind of achievement only because of the far-sightedness of a person from the future. Unfounded guesses, even with a little bit of evidence, would be rejected by foreigners.
Nagaoka Hantaro said helplessly: "I have also studied abroad, and I can see that white people regard people of other skin colors as inferior. But I firmly believe that in terms of morality and ethics, Asians are far better than Westerners, even though the country
poverty."
There's nothing wrong with saying this, but it feels weird to say it from a Japanese person.
After all, what the Japanese did in China decades later was nothing short of moral and ethical.
However, Hantaro Nagaoka is a pure scholar and does not have any thoughts related to military affairs. Even when Japan later invaded China and carried out "slavery education" in the occupied areas and forced the Chinese to learn Japanese, he said angrily: "(To China),
Japan needs to re-understand this country
The country and the people must fully consider the greatness of this people and their contribution to world culture. Forget it about letting them speak Japanese! However, it is impossible for Japanese people not to speak modern Chinese. We ourselves should abolish the ancient Chinese subject
, learn modern Chinese.”
At that time, many professors and presidents of the University of Tokyo expressed their incomprehension about the actions of the Japanese army. However, the power of the academic community was too small after all, and the Japanese army had long been out of control at that time.
Li Yu said: "Perhaps the fate of the East and the West will indeed reverse after many years, thirty years from Hedong and thirty years from Hexi."
Apart from guessing a "Saturn model", Nagaoka Hantaro has no special contribution. However, he is indeed the originator of Japanese physics, and his disciples and disciples are quite powerful.
His student was Yoshio Nishina, who researched the atomic bomb for Japan.
Of course, even the team led by Heisenberg in Germany did not succeed, and Yoshio Nishina was even less likely to succeed. What's more, Japan has no uranium mines at all. It doesn't even have raw materials. Is it possible to build an atomic bomb just by shouting "Banzai" in the spirit of Bushido?
But in fact, if you think about the atomic bomb, which perfectly interpreted the top theories of atomic physics and the most high-tech weapons in the 1940s, you can imagine how far Japan's physics has developed in just thirty or forty years. They were even in the 1930s
Particle cyclotrons have been built since the 1960s...
After receiving a "Little Boy" shot in Hiroshima, it was Yoshio Nishina who went to the scene to investigate in person what kind of weapons the US military was using, and finally concluded that it was an atomic bomb.
The Japanese Army probably started the atomic bomb project in 1941. Later, the Japanese Navy was defeated, and with nothing to do, they used Kyoto University to set up another team to also study the atomic bomb.
After seeing the power of the atomic bomb, they wanted it even more, and ordered Yoshio Nishina's team to build an atomic bomb within six months.
It's just that the people in the military don't understand the principles at all, let alone nuclear physics. They only hope that with this thing, the empire can stand up again. All they have to do is survive the difficult six months, and then the empire will be new.
tomorrow.
However, as early as April 1945, Yoshio Nishina's laboratory and important information were bombed by the US Air Force. Not to mention six months, six years would be in vain.
The Army didn't care about anything. This was the only hope, so they dragged these scientists to a new base to continue their research. However, they didn't have to worry about it, because it didn't take long for the second "fat man" to arrive.
Later, Japan kept soliciting international sympathy, saying that it was the only country attacked by atomic bombs, which was so tragic. But they never mentioned why they were bombed, haha.
As the second generation of Japanese physicists, Yoshio Nishina wasted his time in atomic bomb research, but later the third generation became really powerful, that is, Japan's first Nobel Prize winner in physics - Hideki Yukawa.
Well, this is all a story for later.
Soon the train arrived in Tokyo, and when they came to Tokyo Imperial University, they went directly to the Faculty of Science.
Anyway, there are many universities that do not separate physics and mathematics, and Li Yu can completely understand.
Hantaro Nagaoka said: "It's getting late. Sir, have a good rest today. We will hold a grand speech for you in the auditorium tomorrow."
Li Yuzhen was a little tired that day. He originally wanted to visit the Neon Country. During the few days he came to Japan, he was either watching the Quanye Expo, visiting schools or rushing on the road. He heard that the hot springs here are good, but the idea just came to him, and his head hit him.
I fell asleep on the pillow.
I slept well that night, because I didn't have to worry about falling off like sleeping on a small bed in a hotel - this time I slept on the floor in a traditional way. It also shows that the accommodation arranged by Hantaro Nagaoka for Li Yu is very large.
Use your heart.
The next day, when Li Yu arrived outside the auditorium of the Faculty of Science, it was already crowded with people. He even found some Chinese people in the crowd.
There is a person Li Yu is quite familiar with because he is so famous: Zhang Taiyan!
He has traveled back and forth between China and Japan many times, so being able to attend today is no exception.
Chinese people in this era really have too much inferiority complex. It is not easy to meet an outstanding Chinese person and everyone wants to see it with their own eyes.
As a top-notch scientific researcher, Li Yu is now even more famous in the Chinese and overseas Chinese circles than in China.
Of course, Li Yu is not good at organizing, and his reputation will not be as good as that of "Kang Shengren" (disregarding revolutionaries).
