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, professor of physics at Tokyo Imperial University, and chemist Masataka Ogawa, acting president of Tohoku University, actually came over in person.
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 in Inukai Takeshi's ear, and Inukai Takeshi 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, However, Tokyo Imperial University is now the highest institution of higher learning 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 Takeshi did not dare to neglect, and hurriedly greeted him: "Why did the two professors visit my elementary school?" Nagaoka Hantaro went straight to the point and said: "Is there a Chinese named Li Yu in your office?" Inukai Takeshi nodded. Head: "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 Yi is still a little confused, is an imperial master so powerful?
However, the other party was an important professor after all, so he had no choice but to do as he was told: "Both of you, please follow me." Takeshi Inukai pointed to the front: "That one is him. He has just been in Yokohama for more than half a day, and 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 science, 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, and Hantaro Nagaoka was older than him, so he even used honorifics when he came up.
Li Yu immediately replied: "I am Li Yu. I wonder who you are?" Nagaoka Hantaro immediately introduced himself: "I am Nagaoka Hantaro, a physics professor at Tokyo Imperial University. I sent a telegram to the Qing Dynasty before. I wonder if you have received it? ?" 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. You can come here Tokyo is our glory." 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 read your papers on rays, thermodynamics and new planets; by the way, there is also the recently released "Fractals and Chaos" ." Li Yu said in surprise: "The two professors pay so much attention to me." Nagaoka Hantaro smiled: "There are not many people who are doing scientific research now who have not read Mr.'s thesis." Ogawa Masataka suddenly came back to his senses: "Li Yu He actually speaks Japanese! This is even better. We are still thinking about how to let him give a lecture at Tokyo Imperial University. It is really difficult to find a translator who understands the professional field."
"Still giving 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 make achievements 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 invented things such as the compass and gunpowder long ago, discovered the aurora, and measured the movement of celestial bodies, so I established my confidence to continue studying science." Japan was also a scientific desert before. Like He Yujie, the later meritorious figure in the Department of Physics of Peking University, they were all trying to cross the river by feeling the stones.
Li Yu said: "Professor's perspective and method of looking at history are worth learning from." Nagaoka Hantaro 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 in every aspect." Us! I hope to defeat those white people in 10 or 20 years. But you did it early and did it so well! We are really impressed!" Li Yu said with a smile: "I also agree with what you said, white people It's impossible to be better than us in every aspect." Takeshi Inukai on the side found that the dignified professor of Tokyo Imperial University and Li Yu had a lively chat. It seemed that he was definitely a real talent and learned, not fake.
He asked Ogawa Masataka in a low voice: "Li Yu is really so powerful?" Ogawa Masataka said: "In terms of science, especially mathematics and physics, he can be said to be the best now." Inukai Yi was shocked: "There are actually people in the Qing Dynasty. What is the educational background of such a person?" Masataka Ogawa shook his head: "We don't know anything about his past. We only know that his achievements are very magnificent. Isn't this enough?" Takeshi Inukai said thoughtfully. Hantaro Nagaoka nodded: "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 Takeshi said: "Of course there is no problem. , As long as Li Yu agrees." King Gong and others will stay in Datong School for one day for the time being, and they don't understand science, don't have much interest, and 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 own scientific research direction again: "I am also a staunch supporter of atomic theory, but I have never been able to find anyone 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. I would like to discuss it with my husband." Li Yu said: "Professor, please give me a lecture." Hantaro Nagaoka said from He 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 expectation: "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 seemed that Hantaro Nagaoka's
The “Saturn Model” and Rutherford’s a few years later
The "planetary models" are similar, but physicists have a very vicious vision: one is Saturn with satellites, and the other is the sun with planets.
Essentially very different. Rutherford dared to bring it up
The "planetary model" has its foundation: that is, the famous a-particle scattering experiment. It was through this experiment that Rutherford knew that most of the atomic nucleus was empty, and the volume of the atomic nucleus should be very small.
That's why he proposed something like the entire solar system
"Planet model", because the solar system is also very empty, and the mass of the sun is extremely large. But Nagaoka Hantaro's model is too much like a guess: the system composed of Saturn and its satellites does not have that much open space at all.
If Nagaoka had also done alpha particle scattering experiments, he would certainly 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 honestly: "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 am 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 achievement entirely because of the far-sightedness of a person from the future. Unfounded guesses, even with a little less evidence, would be rejected by foreigners.
Hantaro Nagaoka 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 is nothing wrong with this, but it feels strange 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 later, Japan invaded China and engaged in
"Slavery education" forced the Chinese to learn Japanese, he said angrily: "It is necessary for Japan to re-understand this country and its people. It must fully consider the greatness of its people and their contribution to world culture. Let's Forget it about speaking Japanese! But Japanese people can’t do it without speaking modern Chinese. We should abolish the ancient Chinese subject and learn modern Chinese.” At that time, many professors and presidents of the University of Tokyo expressed their incomprehension about the Japanese army’s actions. , but the power of the academic community was too small after all, and the Japanese army at that time had long been out of control.
Li Yu said: "Perhaps the fate of the East and the West will reverse after many years. Thirty years from Hedong and thirty years from Hexi." Hantaro Nagaoka guessed only one
The "Saturn Model" has no special contribution, but 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. We don't even have the raw materials. How can we build an atomic bomb just by shouting "Banzai" in the spirit of Bushido?
But in fact, if you think of the atomic bomb, the most high-tech weapon that perfectly interpreted the top theories of atomic physics in the 1940s, you can imagine how far Japan's physics has developed in just thirty or forty years.
They even built a particle cyclotron in the 1930s... which took a hit in Hiroshima
After "Little Boy", it was Yoshio Nishina who went to the scene to investigate in person what weapons the U.S. military used, and finally concluded that it was the 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 were 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 the second one didn't take long.
"Fat Man" is here too. Later, Japan has been soliciting international sympathy, saying that it is the only country to be attacked by atomic bombs, which is too tragic.
But they didn’t mention why they were bombed, haha. As the second generation of Japanese physics, Yoshio Nishina wasted his time in atomic bomb research, but later the third generation began to become more 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. How many people came to Japan? During the day, I was either watching the Quanye Expo, visiting schools or on the road.
I heard that the hot springs here are good, but as soon as the idea came to my mind, I fell asleep as soon as my head hit the pillow. I slept well that night, because I didn't have to worry about falling off like a small hotel bed - this time I slept on the floor in a traditional way.
It also shows that Nagaoka Hantaro arranged a large residence for Li Yu and took great care. The next day, when Li Yu came outside the auditorium of the Faculty of Science, it was already crowded. 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’s 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
"Kang Shengren".
