Although he was still at Cambridge University, Chen Muwu had already sent a telegram to Bohr in advance, informing him of the departure time of the ship to Denmark.

But because of seasickness, Chen Muwu chose to stay in Helsingør for one day after getting off the ship, and all the plans originally arranged were disrupted.

So the next day, after Chen Muwu took Oppenheimer from Helsinger on a four-hour train ride to Copenhagen, there was no Bohr waiting to pick him up outside the train station.

Therefore, Chen Muwu can no longer reproduce the situation of Bohr and Einstein arguing on the tram, and neither of them can convince each other.

But the consequences of no one answering the station also showed at the same time, that is, whether it was Chen Muwu or Oppenheimer, neither of them could speak Danish.

In the end, Chen Muwu could only take out an envelope from his bag that Bohr had written before, and according to the address on it, the two of them inquired all the way in half-hung German, and then reluctantly arrived at their destination.

Oppenheimer's German was even a little better than Chen's, after all, he was a descendant of German Jewish immigrants.

Outside Copenhagen, Bledhamswaistrasse 17, a three-storey building with a red sloping roof and neoclassical style, has a sign prominently at the main entrance that reads "Universitetets Institut for Teoretisk Fysik".

Although Chen Muwu doesn't know Danish, he can basically recognize the words, which should be "University Institute of Theoretical Physics".

Next to the institute were two other construction sites, which he didn't know when he first arrived, but they had also been taken over by Bohr, and the scale of the institute was constantly expanding.

Chen Muwu, who was standing on the side of the road, just wanted to walk into the building, when he suddenly saw a small man with black hair and yellow skin coming out of the gate.

His brain is running rapidly, and if the son of a rich and noble family in this era goes abroad to study at his own expense, he basically either studies politics or economics, in order to enter the political arena after returning to China, or take over his own business.

Only a small number of them, like Xu Zhimo, are not good at politics and economics, but they are also obsessed with literature and history, such as literature and philosophy, or artistic disciplines such as painting and music.

But no one will study abroad at their own expense to study some thankless pure science and engineering disciplines such as mathematics and physics.

So basically, all Chinese physics students today are government-funded students who have been admitted to Gengzi indemnity and studied at American universities.

It was rare for him to meet Chinese students studying physics in Cambridge or even in the UK, let alone Denmark, a small Nordic country.

Chen Muwu concluded that this person must not be his compatriot, but should be himself.

It's really strange, not counting the few people who competed with him in the swimming field of the Paris Olympics, this is the first time Chen Muwu has seen a living book.

Chen Muwu was still standing in place and thinking nonsense, but he didn't expect Oppenheimer, who was more actionable, to take a step ahead.

He walked up to the man, greeted him politely, and then asked how Bohr's office should go.

With Oppenheimer's character, he definitely regarded him as a Chinese, so for the sake of Chen Muwu's face, he was so polite.

"Teacher, your compatriot's English is really bad, and I can only rely on Lian Meng to guess."

Oppenheimer's first sentence after coming back was to complain to Chen Muwu.

And Chen Muwu, who had just pricked up his ears to eavesdrop on the conversation between the two, was already very sure that the person was definitely himself: "Robert, that person is not Chinese, according to his pronunciation of 'l' and 'r', there is absolutely no doubt that he is himself." You don't have to be so polite to him. ”

"Yes."

Oppenheimer still asked for the way, he carried his luggage, took Chen Muwu, and walked directly through the long corridor to the end of the first floor.

Unlike Dirac, a puritan-like ascetic roommate before Chen Muwu, Bohr should be regarded as a representative of hedonism.

Although the entire institute does not occupy much space, he still built himself a magnificent office on the first floor.

Soon after the knock on the door, the room heard the words "Kom ind." sounds.

Thanks to the fact that the Danish language is almost the same as the English, the two of them were able to understand the sentence.

Like Capitsa, Bohr was a terrifying person with extremely social skills.

He was sitting behind his desk and spitting clouds, when he heard the sound of the door being opened, he looked up and found a yellow and a white man standing at the door, and immediately greeted him heartily: "Dr. Chen, I have been looking forward to you, and I have finally brought you here." ”

Although he had never seen Chen Muwu in person, Bohr had already seen many photos of Chen Muwu from newspapers that carried news about the Olympic Games.

"Hello, Professor Bohr, I'm sorry to have arrived a day later than scheduled, because I got seasick in the North Sea, and I had to rest for the night in a hotel in Helsingør."

"I see, I said why I waited outside the train station in Copenhagen for a long time yesterday and didn't see you. Today I read in the newspaper again that the ship had come to port, and if you hadn't been there right now, I would have sent someone to Helsingør to look for you. It's just that I didn't expect that an excellent swimmer would get seasick. Please take a seat, Chen. ”

There was a young man sitting on the sofa in the office just now, but when Chen Muwu and the others came in, he also stood up.

When Chen Muwu recognized Bohr, he also recognized that this person should be Heisenberg, who is now working as Bohr's assistant in Copenhagen.

To be honest, Chen Muwu called him a young man in his heart, which was really a bit excessive, because after all, Heisenberg was a year or two older than him.

Although Heisenberg had written to Chen Muwu before, he never thought that Chen Muwu was so young.

After seeing the real person in the newspaper photo, Heisenberg was faintly unconvinced.

Moreover, the question about why the electron spin factor is 2 that he asked Chen Muwu in his letter was actually solved by an unknown person named Dirac at Cambridge University.

This made Heisenberg even more angry, he felt that this Englishman, who had never heard the name before, must not have relied on his true talent to learn, but Chen Muwu secretly revealed the answer to his question.

Now that he sees a real person, he thinks that Chen Muwu is nothing remarkable, everyone is a person with a nose and two eyes, how can he be smarter than himself? It's just a bit of luck.

"Professor Bohr, this person is Robert Oppenheimer, who just graduated from Harvard University in the United States this year, is a student of Bridgeman, and is now a graduate student in the Cavendish laboratory."

"Chen, I would also like to introduce you to Werner Heisenberg, the tall foot of Professor Sommerfeld, who is now working as a teaching assistant with me. The three of you are all the same age, so you should be closer to each other. ”

"Dr. Heisenberg, a great name for a long time, we have exchanged letters before."

The three men took turns shaking each other's right hands.

There was a bit of arrogance in Bohr's words, and he unconsciously thought of himself as the commander of the other three.

This made Oppenheimer on the side a little unhappy, because Chen Muwu and Bohr were both Rutherford's students, and it stands to reason that the two should be equals.

Now that Bohr has made such a come, doesn't it mean that he, Oppenheimer, has now become Bohr's disciple grandchild?

Fortunately, the physics community is far less sensitive than Deyun Club in terms of seniority, and after all, it was Chen Muwu who was invited, and he was just an accessory brought by the teacher in a good mood, so he didn't have a seizure in Bohr's office.

Maybe Oppenheimer subconsciously had already tacitly accepted Chen Muwu as his own teacher, and he didn't react at all to the other meaning of Bohr's words, the three of them were all equals.

……

After a few more small talks in this office, the sun was already directly above the head.

Bohr invited Chen Muwu and his entourage to lunch, and by the way, he personally took the lead in introducing the layout of the building of the Institute of Theoretical Physics to the two new visitors.

Only half of the entire three-storey building is actually used for academic research.

Bohr not only built himself a large and bright office, but also used the entire second floor as an apartment for himself and his family.

On the third floor, on the top floor, there is a dining room, maids, concierges, and student dormitories, as well as guest rooms for scholars like Chen Muwu who come to visit the institute.

Like the open lab on the first floor of the Cavendish lab, Bohr gathered all his students into a large workshop, perhaps to give them a spark of ideas to brainstorm.

As the group passed by the workshop, there was indeed a lot of gossip inside, just as Bohr had envisioned.

Although English and German are not so standard, Chen Muwu can still reveal the youth and vigor from the crack in the door, and feel completely different from the old-fashioned Cambridge University.

In addition to Bohr's office, there is also this workshop, a well-stocked reading room on the first floor, and a lecture hall with six rows of wooden benches.

In the other corner of the hallway, there are two other small labs, and at the end of the hallway there is a staircase leading to the dark, damp basement where Bohr has set up his main lab.

As it is the Institute of Theoretical Physics, Chen Muwu is glad that his teacher Rutherford did not choose to visit Copenhagen, otherwise he would have been half angry by the layout here.

"Chen, I really don't know that you still don't drink. This is the most famous Carlsberg beer in Copenhagen and even in Denmark, and my building was finally built thanks to the foundation left by Mr. Carlsberg. ”

Sitting in the dining room on the top floor, Pol said, raising his glass.

From the beginning of the journey, Bohr was proud in the tone of his introduction to the two, this building should be the most proud achievement of Bohr in addition to the atomic model.

Although the atomic model seems to have been overturned by the Chinese genius in front of him, Bohr thinks that at least this building, Chen Muwu will still have some difficulty in overthrowing him.

Although the two of them had only arrived this morning, Bohr had prepared a small family banquet for Chen Muwu and them in a hurry.

In addition to the celebrity Heisenberg in front of Bohr's eyes today, there was also his wife Margaret.

Chen Muwu did not drink alcohol as usual, and he was not interested in the Danish food on the table.

For more than three months after Ye Gongchao left, Chen Muwu always thought about his little brother's goodness.

In addition to Chinese cuisine, there are also delicacies from the mountains and seas that he eats every day at De Broglie's house in France, and the food from other parts of Europe is basically impossible for him to see.

In the Danish food in his memory, Chen Muwu only knows that if he doesn't pay attention to it, he may buy "Danish cookies" produced in Indonesia.

But Bohr was really calm, just in the office, the time was too short.

At the dinner table, he still didn't talk to Chen Muwu about the bombs that the latter had recently dropped in quantum mechanics, but only about his four gold medals in swimming at the Olympics.

"Chen, you know what? I came close to the 1908 London Olympics, but I was studying for a master's degree in mathematics and turned down an invitation from the Danish national team.

"But my brother Harald captained the team that year, beating France 17-1 in the semi-finals, only to lose 2-0 to England in the final."

The martyrs are in their twilight years, and their hearts are strong.

Although nearly 20 years have passed, Bohr is still excited when he talks about the past.

"Mr. Bohr, maybe it was because you didn't participate, so the Danish team could only win the silver medal that year."

Eating people has a short mouth, since Bohr said that he was prosperous, Chen Muwu also followed with a compliment.

Although he knows very well that even if Big Bohr does compete, he will not be able to return to the sky.

Because in those days, the United Kingdom, as the birthplace of football, really swept everything in its football level.

Even the athletes they sent to the Olympics were amateurs, but even so, they won the championship of that Olympics.

Bohr, of course, also knew that Chen Muwu was saying kind words, and he did not continue, so as not to humiliate himself in front of this Olympic gold medalist.

He naturally changed the subject: "How is the teacher doing?" It's been a long time since I've been back to England to visit his old man's home. ”

"Sir Rutherford's body is as strong as a cow, and if he were to cover his head with a cloth, I think he is more like a lad than I am. It's just that the teacher is very dissatisfied with you now, and he said that you can study the theory by yourself, so why do you want to lead me astray. ”

Chen Muwu didn't lie, the experience of planting potatoes in the New Zealand countryside in the early years left Rutherford with a very tough figure.

After arriving at Cambridge University, he did not leave behind sports, playing golf, cricket and swimming.

Rutherford also forced the exercise-free young people in Cavendis's lab to walk outside.

So when he died of illness in 1937, Kapitsa, who was far away in Sulian, did not believe in this matter at all, and although he could not go abroad, he still wrote letters everywhere to inquire about the truth of this matter from his classmates in his early years.

Rutherford's untimely death has always been a piece of Chen Muwu's heart.

Although he risked upsetting his teacher, he would always persuade Rutherford to smoke less cigarettes every time they met, although with little success.

Bohr, who was pierced by the last sentence of Chen Muwu's nonsense, was embarrassed at first, but after thinking about it, he simply picked out his attitude.

"The teacher is right, Chen, I think the Cavendish lab is good, but it's not for you. You are still young, you should not be like those old guys who are in the twilight, devote all your good youth to physics experiments, I believe that the future of physics must be a discipline where theory is king.

"Chen, are you interested in staying at the Institute of Theoretical Physics? If you wish, I can get you a professorship at the University of Copenhagen. ”

Bohr's words made a wish, which made Heisenberg on the side secretly jealous.

He is also a young man who graduated with a doctorate at the age of 22 and is also a genius, why did he come to Copenhagen by himself and could only work as an assistant in a theoretical research institute. But Chen Muwu hasn't done anything yet, and he is already going to be assigned a professor's position?

Chen Muwu didn't know Heisenberg's thoughts, but he was also not interested in Bohr's conditions.

The attractiveness of the professorship at the University of Copenhagen is not even comparable to the Lucasian professorship in mathematics at Cambridge University, and even far less than the theoretical professorship that Rutherford said he would set up for Chen Muwu in the Cavendish laboratory.

And staying in Copenhagen, the top boss can still scold Kramers for depression and Schrödinger for Bohr who has a fever, Chen Muwu doesn't want to make this trouble for himself.

"Thank you, Professor Bohr, for your kindness. However, this matter still has to be considered in the long run. I have a big project at the Cavendish Laboratory, and we're working on the world's first electron microscope for a while. ”

Seeing that the proposal was rejected, Bohr still looked happy.

According to the previous discussion, his junior brother would have to live in Copenhagen for a month or two, and he thought that during this time, he would always find a way to let Chen Muwu stay.

The atmosphere at the table was still harmonious, and it was not until near the end of the luncheon that Bohr glanced at his students again.

Heisenberg stood up with his wine glass and faced Chen Muwu and Oppenheimer: "In order to welcome the arrival of the two of them, the young people of our Institute of Theoretical Physics have specially prepared a ball for Dr. Chen and Mr. Oppenheimer tonight. ”

Bohr's wife, Marguerite, echoed: "Werner is right, Mr. Chen, you young people should spend more time with young people.

"These young talents from our Institute of Theoretical Physics are the ideal lovers of the girls in Copenhagen, and you can't imagine how sought-after these lads are in their eyes."

Bohr eventually used his beauty scheme, and his student Heisenberg and his wife Margaret were accomplices in this scheme.

Although Heisenberg was a little jealous of Chen Muwu now, when the teacher proposed to hold a ball, he raised his hands in approval.

He is at an age when hormones are overflowing, and he wishes that Chen Muwu could come to Copenhagen every day.

Hearing the ball, Oppenheimer was also in good spirits.

Although he is an honorary graduate of Harvard University, this does not prevent him from being a player at the same time.

After a few months of inhibition at Cambridge University, Oppenheimer still wanted to indulge in tonight's upcoming prom, although he had always been admired and chased by Chen Muwu, who was also a teacher and friend in front of him.

All he wanted was to dance with the girl in his arms at the ball, and feel the breath of the opposite sex up close.

This is already the most exciting thing for young people today.

As for the things that go further, in Europe in the twenties of the twentieth century, it was still an act to be spurned by others.

But Bohr's beauty plan was not destined to succeed.

At this time, Chen Muwu was sitting in the corner of the room, watching the red men and green women in the venue dancing to the sound of music, and there was no wave in his heart.

The dance he danced with Eve at Debroil's house last time was always a threshold that Chen Muwu couldn't overcome.

First, he felt as if he had fallen in love with the beautiful, enthusiastic and generous French girl.

Second, I feel that my dancing skills are so bad that I don't want to be embarrassed anywhere, including today's makeshift dance floor in the lecture hall on the first floor of the Institute of Theoretical Physics.

Moreover, Marguerite invited a beautiful girl from Copenhagen with the aesthetics of the Nordics, which in Chen Muwu's eyes was not as good as the 2,000 gold of Marie Curie's family.

However, Chen Muwu, who was sitting in the corner, found another thing that was very interesting.

That is, at this ball, the two players Oppenheimer and Heisenberg, their feelings for each other quickly warmed up.

In the original time and space, one of these two people was the head of the "Manhattan Project" of the United States and the Allied Powers, and the other was the head of the "uranium project" of Germany.

These two men and their teams once competed in the air to see which side would be the first to develop the weapon of mass destruction in human history, the atomic bomb.

And now, as the two young men with the best dancing skills in the audience, they sat side by side at the end of the song - it was rare that Oppenheimer had forgotten his teacher sometimes.

If everything goes according to the original history, then counting Chen Muwu, on the dance floor of this ball tonight, there will be the heads of the atomic bomb projects of three countries.

It's really a gathering of evil scientists!

But in fact, one thing Chen Muwu didn't know was that in addition to him, Oppenheimer and Heisenberg, in fact, among the people present tonight, there was a fourth person who also directly led their country's atomic bomb program in the original time and space.

Congratulations, Lao Zhao is rare to be on time today. Can't be lazy anymore!
