"Lord Hantaro Nagaoka:
“Seeing the words is like seeing the face.
"I haven't contacted you for a long time, teacher. I wonder how your teacher is doing lately?
"When you receive this letter, I should have left the Institute of Theoretical Physics at the University of Copenhagen in the Kingdom of Timor and arrived at Leiden University in the Kingdom of Holland.
“I’m thinking about whether I should change my research direction and no longer be obsessed with purely theoretical physics research, but return to experiments.
“What gave me this idea was that I met the Chinese physics genius Chen Muwu at the Institute of Theoretical Physics.
“Although I am very embarrassed, I have to admit that in the field of theoretical physics research, I think I am not even remotely comparable to this young Chinese.
“During a conversation, I asked him about the mainstream direction of the future development of physics. Unexpectedly, the answer he gave was not the theory of relativity or the atomic nucleus, which are very popular in the physics community today, but the superconducting effect.
"During the chat, I carefully observed the Chinese man's expression and demeanor. When he answered the questions, his logic was clear and he gave detailed examples. I could feel that these were the results of his careful consideration and were not improvised or made up randomly. .
"So after thinking for a long time, I plan to go to the Low Temperature Physics Laboratory of Leiden University to find out whether studying superconducting effects is a way out for the future of physics.
“I think Imperial University should also develop a set of low-temperature refrigeration equipment on its own or purchase it from the West. Our research on low-temperature physics and superconducting effects should also be established as soon as possible.
"After I arrive at Leiden University, I will conduct an on-site inspection of the cryogenic technology there, and then write a letter to you, teacher.
“If you need to purchase relevant equipment, you can ask the teacher to write a letter and let the students purchase it on their behalf.
"Please give me some advice.
"Nishina Yoshio's tribute"
…
As Yoshio Nishina said in his letter to Hantaro Nagaoka, a professor at Tokyo Imperial University, at the dance that night, he was still suspicious of Chen Muwu at first, thinking that this cunning supporter would not tell what he was thinking. Say it.
But as the conversation progressed, Yoshio Nishina felt more and more moved by the "sincerity" revealed in Chen Muwu's words.
Especially when Chen Muwu said that as an Asian, he was struggling in Europe, being restricted and bullied everywhere, Nishina Yoshio felt the same.
These Omi ghosts are really bullying people too much.
Heisenberg of Copenhagen is even considered the better among these people.
The most outrageous thing was the Pauli I met when I was studying in Germany. Who the hell was he!
He is young and arrogant, just because he is a European.
Did he make any contribution to the development of physics?
On the other hand, Chen Muwu, who was a few years younger than Pauli, had made countless achievements in physics, but he was also very humble in his dealings with the world. To use an idiom, he was extremely humble.
So before the dance ended, Yoshio Nishina almost completely accepted the very pertinent advice of Chen Muwu, who had the same problem as himself.
He plans to leave Copenhagen and first go to the Netherlands to see what is going on at Leiden University before making the next decision.
However, even though he completely trusted the Chinese man in front of him, Nishina Yoshio was still not completely honest.
After hearing Chen Muwu say that he would spend at least two months as an exchange student at the Institute of Theoretical Physics in Copenhagen, Nishina Yoshio made a small calculation in his mind.
If I could successfully find the superconducting properties of thallium metal within this two-month time gap, wouldn't I be able to successfully cut off Chen Muwu's next achievement in advance?
He is neither a drug nor a husband, not to mention the achievements of Chinese people. Yoshio Nishina has no burden or pressure at all.
But Chen Muwu didn't tell the truth completely to Nishina Yoshio.
Before he even arrived in the UK, he had already established a firm foothold in the European and American physics circles with his two papers.
After arriving at Cambridge University, everyone loved him, and flowers blossomed. Not only did he have the calf-protecting Rutherford and Old Thomson, but Eddington, who had always been a gentle gentleman, even beat someone because of him.
Moreover, Chen Muwu's height and appearance are completely incomparable to Nishina Yoshio.
If he were told that there were many beautiful girls in Europe who had a crush on him, I wonder if this short, round-faced fat man would burst into tears, break down, or even commit seppuku after hearing this?
…
"Well, Dr. Chen, you just arrived in Copenhagen and you poached one of my students. I thought you were both from the Far East and you should have something in common with each other. I didn't expect you to be so unkind to him."
After a few days of sightseeing in Copenhagen, Chen Muwu once again met his senior brother Bohr in the office of the Institute of Theoretical Physics.
As soon as they met this time, Bohr gave him a "boost".
But seeing the smile on his face, Chen Muwu could guess that what he said was probably a joke.
"Professor Bohr, you are really good at telling jokes. I have more topics in common with a pig than with a human being."
"Do you have anything in common with the Germans who invaded Schleswig, Denmark?"
Just after he finished speaking, Chen Muwu felt that the last sentence was a bit inappropriate.
Bohr, who was sitting behind his desk, kept glancing at Chen Muwu. Not only were they two people in this office, but also Bohr's close assistant, the German Heisenberg, was sitting on the sofa.
"Uh," Chen Muwu hurriedly went back to make up for it, "Werner, I was just making an analogy. Forget it, let me put it in a way that is more acceptable to you.
"Faced with the French who invaded Alsace and Lorraine, and the Poles who invaded Danzig, would you, as a German, talk to them without any trouble in your heart?"
After thinking for a while, Heisenberg gave his answer: "Well, how to put it, although I hate French people and Polish people, but if we are just talking about science, I don't think we should care about their nationality. .My teacher Professor Sommerfeld, Professor Planck in Berlin, and Professor Einstein, all of them have many good friends in the French physics community."
"Werner, you are wrong. Although science has no national borders, scientists do have nationalities.
"And most people in this world don't think like you do. In the two consecutive International Congresses of Mathematicians and the two consecutive Solvay Conferences, the Allies led by Germany were not allowed to participate. This is to refute you. The best example of this kind of naive thinking.
"But I still have to apologize for my behavior. I didn't want to see someone who made me unhappy in Copenhagen, so I took it upon myself to find a reason to send him to the Netherlands.
"Professor Bohr, I hope you can forgive me."
Chen Muwu's attitude of admitting his mistake was very sincere.
But everyone was "sent" away by him, so what's the use no matter how good his attitude of admitting his mistakes is?
"Chen, you don't have to blame yourself too much. As a visiting scholar at PeopleSoft, of course he has the freedom to come and go,"
Bohr paused after saying this, and wanted to take out his pipe and light one.
But he also remembered that Heisenberg had told him that Chen Muwu didn't like the taste of tobacco very much. Bohr, who hoped to leave a good impression on him, had a battle between heaven and man in his brain for a while, and finally gave up the idea of smoking.
"If possible, I would rather send away ten or even a hundred PeopleSofts, just to exchange for you staying in Copenhagen."
"Uh...Professor, you really value me too much."
Chen Muwu did not expect that Bohr could forcefully switch to this topic in a place like this.
"It doesn't matter, we have a long time to come. I think I have enough time to allow you to stay here." Bohr forced a smile on his face.
"But, then again, Chen, do you really think that research on superconducting effects will be the mainstream development direction of physics in the future?"
This Nishina Yoshio's mouth is really looser than the old lady's cotton waistband.
He could just leave quietly by himself, why would he tell the world? No wonder Oppenheimer's mood has not been very high these days.
Could it be that after listening to the message, he also felt that superconductivity would be the mainstream of physics in the future, and then thought that he, the teacher, was hiding something?
Alas, I'll have to find Oppenheimer to explain it later.
But now, he still has to deal with Bohr and Heisenberg in front of him.
"Well, Professor Bohr, it is undeniable that physicists still know too little about low-temperature things.
"I don't know if you have seen it. In my second paper on Chen Statistics last year, I discussed the existence of a condensed matter.
“I have always been interested in whether this kind of condensed matter exists. Maybe after I finish this battle in quantum mechanics, I will go back and study low-temperature physics.
"Of course, we don't rule out studying superconductivity by the way."
The first half of the talk about working on condensed matter is completely nonsense.
But in the second half about superconductivity, Chen Muwu told the truth.
He really wanted to, and at the same time, he had to study issues related to superconductivity.
If he doesn't make some achievements in superconductivity, it will be a matter of time before Yoshio Nishina realizes that he has been cheated.
Now that the pie has been drawn, it is time to bake the pie, so that it has a beginning and an end!
Bohr did not delve into Chen Muwu's words. Anyway, as a purely theoretical physicist, he was not very interested in any experiments.
"Okay, Chen, if you think there is a need to study superconducting effects, I certainly support you in trying it. But as you said, the top priority right now is to win the tough battle of quantum mechanics. I hear Say, you received a lot of resistance from Einstein’s side?”
Chen Muwu nodded: "That's true. It seems that Dr. Einstein's philosophical philosophy made him attach great importance to the law of cause and effect."
"He has indeed become a bit stubborn recently and has become cautious in physics. However, Chen, I personally agree with your point of view, and so does Werner."
Bohr looked at Heisenberg, who quickly nodded in agreement.
"The entire Institute of Theoretical Physics agrees with your point of view."
"Professor Bohr, this is a great honor for me."
"Chen, I'm thinking about this. Can you take the opportunity of your coming to Copenhagen to give some open classes to the young people at the Institute of Theoretical Physics? Tell them about your quantum mechanics?
"I think that if there is really a war, only one general is not enough. If the general has no soldiers, then he becomes a mere commander in name only.
"This group of boys in Copenhagen are very enthusiastic about physics, especially your quantum mechanics. If you can train them a little, then this will definitely be a new force with high combat effectiveness and can help you fight. Win the quantum battle.
"Chen, don't worry, you will definitely be paid for the labor fees for this course."
"Professor Bohr, you are so kind in your speech. Being able to give lectures at the Institute of Theoretical Physics is also something to be proud of. I am just afraid that my level is not enough, and I will make people laugh and mislead others."
Chen Muwu is already very good at giving lectures, especially quantum mechanics.
He had already tried the waters once before with the Kapitsa Club of the Kapitsa organization.
Then he followed Rutherford's arrangement and gave a series of lectures to people of all ages in the Cavendish Laboratory.
Chen Muwu can now stand on the podium without any stage fright no matter how many people are sitting below him.
But as for how much the audience understood, he couldn't guarantee.
This is not because what he said is too obscure and difficult, but because the steps are too big and the content is a bit too advanced for today's people to accept.
…
After agreeing to Bohr's invitation to give lectures and pretentiously preparing for two or three days, Chen Muwu began to lecture a group of young people in their twenties and thirties about quantum mechanics "founded" by him in the lecture hall of the Institute of Theoretical Physics. .
Oppenheimer, who had already heard similar content twice, was promoted to teaching assistant for this course.
As a bachelor's degree graduate, he understands quantum mechanics better than the Ph.D.'s here, which makes him very proud.
Chen Muwu spent a long time talking about the superconducting thing he had talked about with Yoshio Nishina before, and finally explained it clearly to him.
After hearing that, as he had imagined when he left the meeting, the teacher had indeed deceived the unpleasant person with false news, Oppenheimer finally became happy again.
He knew that the teacher would not lie to him.
…
Compared with the ancient Cambridge University, Copenhagen, which is full of young people, can be said to be an uninterrupted "youth storm".
These peers may respect Chen Muwu who imparts knowledge to them in class.
But in every spare time, in addition to asking questions, many people came to Chen Muwu and Oppenheimer and invited them to do various activities: such as going to the cinema in the city center to watch newly released movies, and going to sing songs. Listen to an opera in the theater, continue the dance in the lecture hall like before, or go to the bar to drink all night.
Only the last activity would be rejected mercilessly by Chen Muwu.
Because Chen Muwu is an Olympic swimming champion, he is naturally indispensable for sports events.
Bohr invited Chen Muwu more than once to take a walk in the beech forest in the Kalamborg Forest outside Copenhagen during his breaks. This was Bohr's favorite form of exercise.
As for the most popular sport among young people in the Institute of Theoretical Physics, Chen Muwu had never imagined it.
pingpong.
The sport of table tennis was popular for a period of time in the early 20th century, but suddenly disappeared in most parts of Europe.
Only in a few countries in Eastern Europe has it continued.
However, in the 1920s, perhaps because of the end of World War I, the sport of table tennis began to gradually recover again.
During break time, no one in the reading room of the Institute of Theoretical Physics loves learning anymore.
Everyone occupied the long table in the reading room, set up a homemade net, took out celluloid balls and wooden rackets, and started playing table tennis with a clanging sound.
The ball-making technology in the early days was not perfect, so the current table tennis ball is shaped like a basketball, with eight celluloid pieces spliced together to form a ball.
Racquets are also very simple. They are wooden boards cut into a round shape with a handle. Only a few people cover the wooden boards with a layer of rubber.
As for skills...
The best among these guys all use chip shots.
And because the score rules completely inherited the twenty-one point system of tennis, this resulted in the game being long, stinky, and uninteresting.
Seeing the table tennis ball, the Chinese genes in Chen Muwu started moving again.
He had been addicted to it a few times. He just used simple fast breaks and smashes, and even without using the loop ball, he beat these Bohr students without any ability to fight back.
People today have never seen this kind of skill before, and they all marvel at Chen Muwu's ability not only to swim well, but also to play table tennis well.
Those who were not convinced even came to challenge them and asked Chen Muwu to give them advice.
After a few rounds, the arrogant voices gradually disappeared, and only the excited Oppenheimer was left shouting on the sidelines.
In the end, the young people at the Institute of Theoretical Physics had to reach a consensus in private.
That is, every time before playing table tennis again, one or two people from the participating athletes will be sent to Chen Muwu for advice on physics issues.
We can't let this sports demon come to the reading room again and ruin their only fun in their spare time.
…
During these days of lecturing, Chen Muwu's impression of Heisenberg went up and down.
In the beginning, Heisenberg would come to the classroom early every time and sit in the middle of the first row, the seat reserved for good students.
Not only did he listen carefully, he also always took meticulous notes in his notebook.
But Bohr, the owner of the institute, only came to the lecture hall occasionally and inspected a few times.
Chen Muwu had never seen his senior brother sit on the bench and listen to a complete class.
He also thought that this was because Bohr was a Nobel Prize winner in physics after all, and he should have figured out what he wanted to express from his previously published papers.
But the truth is that Bohr was a bit embarrassed. He didn't want to sit in the audience and listen to a lecture by a young man who was nearly twenty years younger than himself.
That's why Bohr sent his confidant General Heisenberg and asked him to listen carefully in class, take notes, and repeat them to him when he came back.
Chen Muwu didn't know the twists and turns behind this, and he couldn't stop praising Heisenberg in his heart.
No wonder he was able to graduate from undergraduate to doctoral degree in three years. He never expected to love learning so much.
It's just that this good impression of peers who love learning did not last long.
One morning, Heisenberg suddenly disappeared from his seat in the front row.
Chen Muwu's first reaction was: Could it be that he was sick?
In his memory, it seemed that Heisenberg had symptoms of hay fever.
But then I thought about it, it was already the end of October, and even the chrysanthemums were already in bloom.
And where are the flowers in bloom that can produce pollen that could make Heisenberg allergic?
Chen Muwu and other students inquired and found out that Heisenberg was not sick, but no one had seen him in the institute since this morning.
This made Chen Muwu, who was standing on the podium, secretly complain: It seems that this German's patience is only that much!
Within a few days I couldn’t hold on any longer!
…
However, Heisenberg appeared again that afternoon, making Chen Muwu understand that he had misunderstood him that morning.
Because after opening the door of the guest room on the third floor where he lived, Chen Muwu found that standing outside the door was not only Heisenberg who knocked on the door, but also another person standing behind him.
"Mr. Chen, I didn't disturb your rest, right?"
"No, no, please come in."
“Allow me to introduce, this is another student of my teacher Professor Sommerfeld, who is now a lecturer at the University of Hamburg, Wolfgang Pauli.
"After he learned that you had come to Denmark from the UK, he rushed over from Germany just to meet you. I just picked him up from the train station."
"Wolfgang, this is the one you have always wanted to meet, Dr. Chen Muwu from Cambridge University."
Before Heisenberg introduced him, Chen Muwu had already recognized him as Pauli through his very recognizable eyes.
Why is he here? Fortunately, Copenhagen is the Institute of Theoretical Physics, so there are no experiments to do.
And judging from his face and expression, he looked like he was coming with bad intentions.
Pauli was now somewhat dissatisfied with his junior brother Heisenberg for introducing himself to Chen Muwu first.
Because in his opinion, this was a sign that Heisenberg believed that his status and reputation were inferior to Chen Muwu.
"Hello, Dr. Pauli."
Chen Muwu took the lead in extending his hand.
This situation made Pauli even more angry.
He reached out his hand very perfunctorily and touched Chen Muwu.
Pauli's brows were furrowed from the moment he walked in, and he didn't even say "hello" in greeting.
After he put down his hand, he got straight to the point: "Mr. Chen, I have recently carefully studied several papers you published this summer. Now I want to regretfully inform you of something, that is, I discovered something in your paper. A very ridiculous mistake."
Chen Muwu felt that this sentence sounded familiar.
Not long ago at Cambridge University, he heard this sentence from Dirac who broke into the lecture at the Kapitsa Club.
Today in Copenhagen, Pauli broke into his room and did it again.
Why is it that the first words you guys say when they meet are so disappointing?
