After the photo was taken, the three of them left the hotel and headed for the University of Berlin.

Einstein, who led the way in front, was sullen in his face and heart.

Listening to Chen Muwu and Oppenheimer chatting behind him about some questions about the camera, he recalled the first time he met Chen Muwu on New Year's Day in 1923.

In the beginning, the lecture of the Ministry of Industry was no different from the many lectures he had held in Europe, the United States, and Japan.

On those occasions, even if he did not seriously prepare the content of the speech, but stood on the stage and casually said something indiscriminate, the audience in the audience who did not understand the theory of relativity at all, and only wanted to have the capital to boast after returning home, and the vassal elegance would also give him warm applause.

It can be said that in the auditorium of the Ministry of Industry Bureau in the Qihai Public Concession, the last question Chen Muwu asked stood up was the most professional and surprising question among the many lectures Einstein held in history.

For this reason, Einstein did not hesitate to let the organizers disrupt the plan and stayed on the stage for more than half an hour to discuss the solution of the gravitational field equation with Chen Muwu.

After the discussion was forced to end that day, Chattlet, an engineer from the Ministry of Industry, invited Chen Muwu, who stood out in the lecture, to join them at a banquet for Einstein.

Even if you don't want to get to know Einstein, you can get to know all kinds of prominent figures in the public concession, and if you want to get to the top of the table, you will never miss this kind of God-given opportunity.

But Chen Muwu just refused this matter, it seems that this young man who is dedicated to learning just wants to discuss some physics problems with him.

However, three years, just over three years later, the simple young man who liked to discuss physics problems and had no other distractions in his heart had disappeared!

Chen Muwu has been immersed in Europe, especially in England for more than three years, and the purity of this Chinese genius has been eaten away by that hypocritical society, and only sleek and sophisticated are left in the whole person.

What's so nice about the physics department at the University of Berlin?

Is it necessary for him to get along with those strangers?

As long as you achieve enough academically, gain enough prestige and status in the academic world, they will rush to come and slap you!

Chen Muwu, Chen Muwu, you are really confused!

Einstein regretted it all the more and more, and he felt that he had made the biggest mistake he had made in recent years when he sent Chen Muwu to Cambridge University in England by sending him a telegram to Eddington.

This mistake is even more serious than introducing the cosmological constant term into the gravitational field equation myself.

If Chen Muwu had not gone to the old capitalist power, the drunken Britain, but to Germany, maybe he would have learned a little less sleek sophistication.

After all, the Germans couldn't even afford bread at that time, so how could they have any other mind to make something that they didn't have?

But Einstein probably didn't think that the economic crisis in Germany was only aimed at the Germans who made money and spent it in Germany.

The mark depreciated, but the rest of the world's currencies did not, and the exchange rate between them and the mark was even able to rise in response to the economic crisis in Germany.

International students like Chen Muwu can still live a good life in Germany.

If you are the kind of playboy who has a lot of fun and is not shy about it, maybe you can leave the seeds of China in the stomachs of a few German girls before the economic crisis is over.

Thinking of Chen Muwu's regret that he could not come to Germany to study, Einstein began to complain in his heart about Planck, who he entrusted with this matter.

If he had sent Chen Muwu a telegram immediately after receiving his telegram and invited him to study at the University of Berlin, then Chen Muwu would not have become as philistine as he is now.

After not even reading his travel information in the newspaper, he hurried to the train station and intercepted Chen Muwu back to Berlin.

And if Chen Muwu is a student and professor at the University of Berlin, then don't you want to discuss problems with him whenever you want?

Before he arrived at the physics department of the University of Berlin, Einstein already had a deep hatred for the old head of the physics department.

Planck, who was waiting in the office to welcome Chen Muwu's arrival, sneezed twice inexplicably.

The autumn breeze is bleak and the weather is cool, and it seems that it is time to add two more clothes to yourself.

I am about to retire and want to enjoy a few more years of leisure, but I can't get myself into trouble before retirement because I am not careful.

Einstein led Chen Muwu to the campus of the University of Berlin and then to Planck's office.

Oppenheimer also wanted to go in with him, but was dragged back by Einstein.

Although he didn't say a word, his meaning was also obvious, the person Planck wanted to meet was Chen Muwu, a doctoral student who followed Dr. Chen to brush up on his papers and results, and what kind of excitement did he have to follow up.

Of course, Einstein left him behind for another meaning.

"Mr. Oppenheimer, I heard Dr. Chen say that you also know the theory of relativity, and I would like to hear what you think about the unified field theory."

Since yesterday morning, when he and Chen Muwu were discussing the issue of unified theory in the hotel, Oppenheimer has been writing and drawing with a notebook and pen next to him, and it seems that he is also very enthusiastic about this matter.

In the chat, I learned that Oppenheimer had been studying and working with Chen Muwu for more than two years.

As long as he can learn some fur from Chen Muwu, maybe he will be able to talk to himself about the theory of relativity and the unification field.

Not to mention that Einstein pulled Oppenheimer to his office, more than three years later, Chen Muwu finally met Planck, who had been his long-time friend in this office at the University of Berlin.

It's not the first time he's met Planck, after all, in textbooks and on the Internet, you can see many elegant photos of Planck as a young boy, as well as unkempt jade photos in his later years as a professor.

When I entered his office today, I met this master of physics for the first time, and his appearance was exactly the same as the photo printed in the book.

And Planck, the owner of the office, this is the first time he has really seen Chen Muwu.

He wasn't too surprised to see an East Asian with a raw face walk into his office.

Because there were many East Asians studying at the University of Berlin, Planck also used to have students from China, or the Qing Dynasty.

Seeing that this person was still carrying beautifully packaged things in his hands, and his appearance was similar to the photos he often saw in newspapers, Planck immediately reacted, this should not be the school student who accidentally went to the wrong door, but the distinguished customer he has been waiting for today.

Except for Pauli, who doesn't like to read newspapers very much, most of the people at the University of Berlin have seen from the newspapers what Chen Muwu encountered in Poland.

Even if you are a physicist who is famous all over the world, you can't explain why you have a good encounter with soldiers.

Everyone regards this as a pleasure, a pastime and spice outside of daily life.

Even Planck didn't expect that Einstein's mobility would become so high, he saw the news in the newspaper the first night, and the next morning he hijacked Chen Muwu from the train station to Berlin.

He heard about Chen Muwu's presence in Berlin from the two physics department employees who had gone to dinner with Pauli, and then contacted Albert Einstein overnight, expressing his desire to invite Dr. Chen to the physics department of the University of Berlin.

"Professor Planck, after all these years, I finally meet you today. I'm Chen Muwu. ”

"Dr. Chen, welcome! I've heard Xia Yuanzhen, Einstein, Bohr and others mention your name for a long time, and we finally met today. ”

Chen Muwu took a few steps forward, and Planck quickly got up from his seat and stretched out his hand.

After a long handshake, Chen Muwu handed over the gift in his hand again: "Professor, you praised it falsely." These are two bags of tea from my hometown, which is a little bit of caution on my part, please be sure to accept it. ”

The old man only accepted the gift with a symbolic politeness, and his face did not show much surprise.

Most people in Europe like to drink caffeine, and only the two island countries in the British Isles of Britain and Ireland have a heartfelt love for tea.

A large part of Chen Muwu's luggage was tea to bring back to the UK.

Unlike the British who are fond of black tea, among those around Chen Muwu at Cambridge University, everyone has gradually changed to green tea and oolong tea.

Especially in the Cambridge Apostle Society, which is all Gongzi's brother, everyone even launched a retro movement, resolutely resisting the second creation behavior of adding milk and sugar cubes to black tea, but following the drinking method of tea, the birthplace of the drink, just brewing it with boiling water.

Seeing that their posture was so big, Chen Muwu was a little glad that he didn't introduce them to the more complicated and complicated way of drinking tea in ancient China.

He also has an unrealistic idea, that is, if one day, he hits a bottleneck in physics, then he will open a bubble tea shop around Cambridgeshire, and promote this drink to the whole of the United Kingdom like mahjong, which is estimated to make a lot of money.

Planck put the tea back on his desk and invited Chen Muwu to sit on the sofa in his office.

Unlike Einstein, Planck, who was about to retire, had long since bid farewell to the frontline of physics research.

His current focus is entirely on the management of the Department of Physics at the University of Berlin and the review and control of submissions to the Annals of Physics.

The frequent exchanges between Planck and Chen Muwu are also based on the manuscript of the paper sent by Chen Muwu to Planck.

At the beginning, Chen Muwu's first paper sent to the Annals of Physics in Qihai was only because of Einstein's telegram that Planck agreed to publish it.

Planck was as good as a stream, but only halfway through, he published Chen Muwu's paper, but failed to send Chen Muwu an invitation to study at the University of Berlin.

Later, as more and more papers were published in the Annals of Physics, and he made more and more achievements in physics, Planck realized that he had missed a genius who could improve the physics level of the University of Berlin, and gave him to the British in vain.

It only took one year for Chen Muwu to get his PhD at the University of Cambridge.

And he has done all the experiments and research over there, even if he digs the foot of the wall, it is estimated that without a golden hoe, he will not be able to dig up this jade lingzhi.

Planck's remedy was to ask Chen Muwudo to publish an article in the Annals of Physics to help him gain an advantage in the confrontation with the emerging Journal of Physics.

Planck, who had been the editor-in-chief for many years, did not want to see this old German physics journal, so it was ruined in his own hands.

So after saying hello, Chen Muwu and Planck fell into a kind of polite cycle: the former expressed his admiration for his predecessors in physics, while the latter expressed his gratitude to the former for sending so many papers.

Finally moving on to the next topic, Planck began to invite Chen Muwu again, hoping that he would stay in the physics department of the University of Berlin.

"Dr. Chen, when you came into my office today, although you hadn't introduced yourself yet, I knew that it was you. And at the first sight of you, I even had the illusion that you came today not only to greet me, but also to take over my class and help me inherit the career in this school. How about the position of head of the physics department," Planck turned around and patted the back of his chair with his hand as he spoke, "until now." ”

Well, forget it.

He Chen Muwu dared to agree to Planck's invitation this morning, and Pauli dared to come to him with his sword to duel this afternoon.

Moreover, this position is not very attractive to him, and the racism in Germany will only become more and more serious in the future.

Why bother?

Prescient Jews like Pauli, Einstein, and Born all found a way out for themselves in advance.

Although Planck the Elder was an authentic German, he was also a German who loved Germany very much, and although he was able to stay in Germany justifiably, he became the worst one.

Loyalty is not absolute, it is equal to absolute disloyalty.

Because of his sympathy for the Jewish physicists and scientists in Germany, Planck became the target of criticism from racists who claimed to build Aryan physics, declaring him a "white-skinned Jew" and openly questioning whether his famous masterpiece, the first formula for thermal radiation to propose the quantum concept, was plagiarized from someone else.

On the one hand, as a representative figure of the German physics community, Planck was held high on the altar like a mascot.

On the other hand, there are many young people under the altar, who attack and abuse him openly or secretly.

During the war, Planck, who had long since retired, maintained this state of dire straits.

At the age of eighty-six, he witnessed the defeat of his beloved motherland in the war for the second time.

Although it was Planck's misfortune to stay in Germany, it was also his fate.

Even if Chen Muwu invites him to Stockholm in the future, it is estimated that Planck will never leave Germany.

He had all the opportunities to leave a long time ago, but he still stayed without hesitation and stayed with his homeland.

Looking at the old man in front of him who was happy and longed for a leisurely life after retirement, Chen Muwu really couldn't bear to think of all the tortures that life had done to Planck in the future.

After visiting Planck, Chen Muwu visited the physics department of the University of Berlin with the old man, and listened to him introduce himself to a certain laboratory where Kirchhoff once worked, and in a certain office, he met Helmholtz for the first time.

Planck also unconsciously showed a happy expression on his face, as old Thomson had done when he recalled Lord Kelvin and Baron Rayleigh III.

But no one wants to believe that happy times always pass in a hurry, and there will be more suffering in the future.

After doing all this, Chen Muwu, accompanied by Planck, had lunch at the University of Berlin.

Einstein and Oppenheimer sat down with them, wondering what they had done on the morning of their visit.

Looking at the expression on his face, it seems that he is getting along well?

At the dinner table, Planck proposed that Chen Muwu give an impromptu lecture to the students of the University of Berlin in the physics department this afternoon.

The person himself has not yet expressed his position, but Einstein, who was sitting next to him, excitedly expressed strong opposition.

"No, absolutely not! Dr. Chan has already made an appointment with me this afternoon, right, Dr. Chan? ”
