Unlike before the Nobel Prize ceremony, when the Institute of Theoretical Physics had a great deal of physics, Copenhagen is deserted.

Most of the other guests who went to Sweden for the award ceremony had already returned to their respective countries, and Bohr's students had largely returned to their home countries for Christmas, just like Heisenberg and Pauli.

Therefore, Bohr said that in Copenhagen to celebrate Chen Muwu's victory in physics, in addition to Chen Muwu and his party of four, there was only Bohr and his family.

In Copenhagen, Bohr sent Chen Muwu the Berliner Zeitung a few days ago.

The newspaper has now basically become Einstein's "royal" voice newspaper, and they also interviewed Einstein again, asking him about Chen Muwu's Nobel Prize, Chen Muwu's suggestion at the award ceremony that Einstein's gravitational field equation was wrong, and Chen Muwu's statement that the universe is constantly expanding.

This time, Einstein surrendered completely, saying that he had just learned the news, and that he would think about the physical meaning of the cosmological constant term in the gravitational field equation after he returned.

Albert Einstein also called on more astronomers around the world to make further measurements of galaxies beyond these galaxies.

If the truth is really like the data listed by Chen Muwu, the universe we live in is indeed in the process of gradual and interrupted expansion, then Einstein said that he would not hide it, and would have generously admitted that he had made mistakes.

In the Berliner Zeitung, Einstein once again shouted to Chen Muwu in the air.

Albert Einstein advised Chen Muwu that there was no shame in admitting his mistakes. He has already admitted his mistake this time, and at the same time, he also hopes that Chen Muwu can admit that probability waves and uncertainty principles are two wrong theories, just like himself, and quickly give up these fanciful ideas.

Einstein made a move to retreat into advance, paving the way for a long time, and finally wanted Chen Muwu to give up the two "violent theories" he put forward in quantum mechanics.

But this time his punch hit the cotton, and of course Chen Muwu would not give in.

Chen Muqiao was a little worried about his brother's behavior, and he remembered Einstein as the world's most famous and greatest scientist who repeatedly appeared in the major newspapers in Shanghai.

And it was this Einstein who, when he went to Qihai to give a lecture, discovered his younger brother Chen Muwu with his discerning eyes and recommended him to study in Europe.

In Chen Muqiao's heart, Chen Muwu should not point out Einstein's mistakes on such a solemn occasion.

The Chinese have always paid attention to respecting teachers, and his merciless criticism of Einstein is completely an act of deceiving teachers and destroying ancestors.

The Luo Cheng in the Peking Opera "Silt River", wasn't it because he deceived his teacher and destroyed his ancestors, and learned the method of breaking two guns with one gun from his father-in-law Ding Yanping, and forced Ding Yanping to death when he turned his head, and lost ten years of Yangshou, so he was shot to death by Su Dingfang in the silt river at a young age?

Although most of this story is attached to the romance, the truth is that truth.

Chen Muqiao thought that Chen Muwu's approach was very inappropriate, so after Bohr's reception dinner, he put forward his own views with his younger brother in the room.

"Third brother, I remember this Dr. Einstein from Germany, whether it was in the sea or in the letters you wrote to your family after you arrived in Europe, he helped you a lot.

"My family is very grateful to Dr. Einstein, and even my mother told me before I left that if I can meet Dr. Einstein in Europe this time, I must thank this senior who took good care of you for her.

"Isn't it a little too much for you to make the situation like this now?

"I think I'm going to have to go back to England by land anyway, why don't I accompany you to Berlin, the capital of Germany, tomorrow after leaving Denmark, and come to accompany Dr. Einstein?" ”

Chen Muwu has achieved so many achievements in just two years since he came to Europe, and now even when Chen Muqiao talks to him, he unconsciously becomes cautious.

Chen Muwu didn't want to evaluate his eldest brother's idea, but now that the time was tight and the task was heavy, he really didn't want to take a detour to Berlin again.

"Big brother, he has already admitted his mistakes in the newspapers, and if I go to Berlin now, wouldn't it seem a bit 'better to chase the poor'?

"I myself respect Dr. Einstein very much, but one is one, two is two, physics is not human, he made mistakes, I can't refer to the deer as a horse like Zhao Gao, right?"

Misfortune came out of his mouth, and Chen Muwu unconsciously burst out a poem that should not exist in this world.

Fortunately, Chen Muqiao didn't care about this sentence, he always felt that his younger brother was answering whether he was secretly changing his concept, or trying to persuade Chen Muwu to go to Berlin to apologize to Einstein.

But no matter how he persuaded him, Chen Muwu just didn't listen to his opinion, which made Chen Muqiao feel a deep helplessness that his younger brother couldn't help it.

The next day, the group of four said goodbye to Bohr in Copenhagen and continued their journey back to England.

From the island of Zealand, where Copenhagen is located, to another Danish territory on the European continent, and then to Leiden in the Netherlands via Germany.

Take the ferry first, then the train, and change trains several times along the way.

Sitting on the train, Chen Muqiao was still a little dissatisfied with his younger brother.

Oppenheimer saw that the atmosphere between the two was a little abnormal, and he wanted to help his teacher ease the relationship with his eldest brother, but he couldn't speak Chinese well, so he could only do it in a hurry.

He can't move Ye Gongchao as a rescuer, although Ye Gongchao can speak Chinese and has a good relationship with both brothers.

But at this time, Ye Gongchao was on the train, rushing to the draft in an extremely uncomfortable posture.

After Chen Muwu's flickering before, Chen Muqiao also thought that it was a good thing for Ye Gongchao to write Chen George's series of books.

Not only can it make money, but it can also reverse some of these foreigners' perceptions of Chinese people to a certain extent.

Although the two brothers are now a little disagreeing with each other, they have tacitly reached an agreement on the matter of "exploiting" Ye Gongchao.

Chen Muwu wanted to divert the attention of his eldest brother and ask him not to worry about Einstein anymore.

So on the train, he confessed to Chen Muqiao, and told his eldest brother his plan to run a school in Europe.

Hearing that the younger brother was going to engage in education in Europe, Chen Muqiao was really interested.

But after the excitement, he felt that Chen Muwu's idea was a little unrealistic.

A few years ago, a semi-official "work-study program in France" was carried out by many well-known figures, but did it end in failure?

How easy is it for his younger brother to single-handedly build a school in Europe to train Chinese students?

Chen Muqiao once again expressed his concerns to his younger brother, feeling that his idea of staying in Europe to run a school was really naïve.

Not to mention anything else, just the funds, Chen Muqiao didn't believe that Chen Muwu could solve it alone.

Indeed, the younger brother won a Nobel Prize in physics for 100,000 yuan, and the books he and Ye Gongchao wrote together also made a lot of money.

The money is a lot less, and it's okay to sponsor the two young people from Beijing to study abroad, as they did before.

But it's not too much, it's not rich to run a school in China, and isn't it a drop in the bucket to run a school abroad?

Chen Muwu has a series of plans to make a fortune in his heart, but he can't talk to his eldest brother now, so he can only vaguely fool the matter of funds, saying that there is a big man who is interested in Chinese culture, the crown prince of Sweden pays money, and he himself just wants to know more about Chinese culture and piggyback on a few more international students.

Chen Muqiao will be suspicious of his younger brother's statement, he originally wanted to let Chen Muwu, who has already obtained a doctorate, do research in Europe for a few more years, and then call him back to China, whether it is Shao University in the north, or Nanyang University in Qihai, to make him a professor, after all, although Liang Yuan is good, it is not a long-term love home.

But before that, Chen Muwu had already shown a strong resistance to returning to China, and suddenly said strange words such as "as long as you return to China, you will be 404".

Moreover, if what his younger brother said is true, the crown prince of Sweden is really willing to pay for such a school out of his own pocket, this condition is still very exciting to Chen Muqiao.

Because Chen Muwu mentioned to him the issue of establishing a technical school, in Chen Muqiao's understanding, this school founded in Sweden should be similar to the Sino-French University founded in France before, which sends Chinese students to work abroad.

Although Sweden is not an old power like Britain, France, Germany, the United States, and Japan, it can also rank second among the great powers.

And Sweden is strategically located, it is also located in Europe. If students can be sent to Sweden to study, it will also make it easier for them to learn and understand the advanced knowledge of the West.

Chen Muqiao proposed another solution to his younger brother.

He said that perhaps after he returned to China, he would come forward to visit the Ministry of Education in Shaojing in person to establish a relationship with the government.

Chen Muwu felt that as the provost of Nanyang University and the second person under the president, he could talk to the Ministry of Education.

Moreover, Ma Xulun, who is now acting as the deputy minister of education, is also from the province, and there is a friendship between himself and him.

If the Ministry of Education of the People's Republic of China really comes forward, then this school established in Sweden modeled after the Sino-French University may really be able to do it.

Chen Muwu felt that his eldest brother should have come up with this idea, but he did have a bad idea.

Under the current Beiyang government, the Ministry's Ministry of Education was at best out of money.

After four years, the city will change the banner of the king, and not only will there be no money, but it may also have to be transfused to the country.

Who can stand this?

Chen Muwu hurriedly stopped his eldest brother's reverie: "Big brother, I don't want to have any contact with the domestic government departments. Although I am far away in Europe, I also know how many times the cabinet has changed in the two years that I have been abroad.

"After a battle between the direct warlords and the Feng warlords, although the little emperor who had been under house arrest in the Forbidden City for more than ten years was kicked out, Cao Kun, who was elected president by bribery, was put under house arrest by General Feng Huanzhang.

"Nowadays, all government departments are too busy to take care of themselves, where is the time to take care of my school?

"Big brother, to tell you the truth, after the ceremony, I stayed in Stockholm for a few more days, just to discuss with the Crown Prince of Sweden about building a school there.

"If nothing else, I guess there will be news from this school by next spring.

"I'm talking to you about this today, just because I want to invite you to do my little brother a favor and be responsible for managing the school's related matters when the school is really completed.

"It's okay for me to give lectures, but when it comes to managing a school, no one I know is more experienced than you, big brother."

Chen Muqiao felt that his younger brother's idea was somewhat unrealistic.

But he didn't want to dampen his enthusiasm too much, after all, the starting point of this matter was good.

So Chen Muqiao half-jokingly agreed: "Well, as long as this school can really be established in the end, then I will resign from my teaching position at Nanyang University and go to Europe to accompany you." ”

It was his inadvertent joke that eventually became a promise that had to be kept.

The four of them spent a total of two days and one night on the road, and finally arrived in Leiden, a small town in the Netherlands, the next night.

As the hometown of the famous painter Rembrandt, Leiden is only a small town in the Netherlands, but Leiden University is the oldest and most high-level university in the Netherlands.

Over the centuries, Leiden scholars have also left many contributions to physics.

Christian Huygens, who proposed the Huygens principle, is a graduate of Leiden University.

It was from him that the wave theory of light gradually replaced Newton's theory of particles.

The first capacitor in the history of physics was also invented in the laboratory of Leiden University.

As a power source for electrical experiments, the Leyden bottle is a major foundation for electrical research.

It was only after the invention of the Leyden bottle that the nature and properties of electricity began to be studied.

In modern times, Leiden University's position in physics should not be underestimated.

Zeeman, who discovered the Zeeman effect;

Zeeman's teacher, who preliminarily explained the Zeeman effect and also proposed the Lorenz transformation of Lorentz;

Van der Waals, who derived the equation of state of non-ideal gases and proposed intermolecular forces;

There is also the main reason why Chen Muwu came to Leiden University this time, the former director of the low-temperature physics laboratory, Camyrin Onnes, who first discovered the superconductivity effect.

These four are the four Nobel laureates in physics that the Netherlands has so far, and they are all professors and alumni of Leiden University.

The number of Nobel Prizes in physics for such a small university is twice that of the United States and four times that of the People's Republic of China.

Bohr used his strong connections to help Chen Muwu find a candidate to receive them in advance.

Professor Ehrenfest of Leiden University, along with his two students, Uhlenbeck and Goodsmit, waited on the platform of Leiden train station long before the train arrived.

These two Chen Muwu peers were studying for a doctorate under their teacher Ehrenfest at this time.

If it weren't for Chen Muwu, they should have been the first to come up with it by mistake two years later, and electrons have spins.

As for Ehrenfest, he was an Austrian Jew who had acquired Dutch citizenship and was a close friend of Einstein and Bohr.

Historically, the latter two physicists, who were not convinced by anyone, often quarreled over questions about quantum mechanics, and Ehrenfest has always acted as a mediator in them.

Einstein and Bohr's most famous photo was also taken by Ehrenfest himself in his own home.

Ehrenfest was also a student of Boltzmann, a professor at the University of Vienna, and in the end he followed in the footsteps of his own teacher and committed suicide.

As soon as they met, Ehrenfest began to greet Chen Muwu with enthusiasm and chatter, which he had prepared a long time ago.

"You must be Dr. Chan, whom Albert has mentioned more than once in his letters to me.

"While he was still lecturing in the Far East, he crossed the ocean and sent me a letter saying that he had discovered a genius of physics in the Far East.

"When you arrived in Europe, I realized that Albert was right, and in just two years, you had already made many major inventions and discoveries in physics.

"Later, I was even afraid to receive and open every issue of the Annals of Physics that came from Germany.

"Because I was scared that there would be papers that you had written, and every time I read them, I realized that I really didn't know anything."

This rainbow fart is really comfortable to praise people.

No wonder both Bohr and Einstein can become friends with the Ehrenfest in front of them.

Chen Muwu hurriedly said politely: "Professor Ehrenfest, you are really a mistake. ”

"Dr. Chen, you don't have to be modest, what I said is true, if it weren't for your achievements, Sweden would not have awarded you this year's Nobel Prize in Physics.

"A few days ago, Professor Einthofen had also returned to Leiden University. The school plans to help you and him hold a celebration banquet to celebrate the two of them winning this year's Nobel Prize. ”

Eintofen, this year's Nobel Laureate in Physiology or Medicine, is also a professor at Leiden University.

More than half a month ago, Eintofen and Chen Muwu arrived in Stockholm one after the other to receive the award.

Now, the two of them have come to Leiden, the Netherlands.

Fate is wonderful.

Uhlenbeck and Goodsmitt stepped forward to help a few people carry their luggage, and then a few of them took the tram to Ehrenfest's house in Leiden.

Chen Muwu suddenly found that after coming to Europe, he went to France, Denmark, Sweden, and now to the Netherlands.

Every time I stayed in someone else's house, I didn't even stay in a hotel once.

It seems that your connections are okay, huh?

After a brief dinner, Ehrenfest invited the guests to the living room for a chat.

Everyone also knows that Ehrenfest mainly wants to chat with Chen Muwu.

So Chen Muqiao planned to rest first under the pretext of being tired from the journey, while Ye Gongchao was bombarded to his room to continue to catch up with the manuscript.

Only Oppenheimer was by his teacher's side, and he would not give up any opportunity to meet his predecessors in physics.

Ehrenfest first chatted with Chen Muwu and introduced him to Leiden University's plan for the Nobel Prize celebration.

He also informed Chen Muwu that he had made contact with the low-temperature physics laboratory and could take him to the laboratory to visit and communicate at any time.

Ehrenfest then introduced the scenery around Leiden and invited him to visit the most famous windmill in the city if he had time.

After chatting so much, Ehrenfest, who was "Xiang Zhuang Dancing Sword, Intended for Pei Gong", finally inadvertently chatted with Chen Muwu about the next topic.

"Dr. Chan, in the last year, Albert and I have exchanged a lot of letters.

At that time, Albert complimented you every once in a while, and even told me that the most important discovery of his life was not the theory of relativity, but the person of you, Dr. Chen.

"However, in the last few letters Albert has written to me, he has some fear of the probability wave and the uncertainty principle you mentioned.

"Albert always felt that the world should not be what you described in quantum mechanics, and even wrote to me that he felt that you had created a monster with teeth and claws to destroy the laws of cause and effect in this world.

"To be honest, the quantum mechanics you founded, and the development and extension of several concepts on the basis of quantum mechanics, I still haven't fully understood it, and you can't comment on who is right and who is wrong between you and Albert.

"Albert is a man with no malice, he is just a little stubborn in his pursuit of truth.

"The two of you used to have such a good relationship, but now you have more and more differences because of different opinions on physics, and I always feel that this is not a good thing.

"Dr. Chen, I have a reluctant request. How about we go to Berlin together after you're done with Leiden, or I write to invite Albert to Leiden?

"The problem between the two of you, it's not a way to drag it out like this, and the relationship will only get worse and worse.

"It's better to meet in person, have an academic discussion, and explain the problems and contradictions between each other clearly."

Well, this is another lobbyist.

It is estimated that Einstein does not know that Chen Muwu has come to Leiden University, and Ehrenfest does not have time to write to him to report the news.

Ehrenfest was able to say this to Chen Muwu, completely following his own heart, this person should be dedicated to the development of physics, and he does not want him and Einstein to turn against each other because of academic problems.

In his previous life, the two people he mediated were Bohr and Einstein.

Only this time, Bohr's position was replaced by Chen Muwu.
