Planck looked disappointed, although he made a temporary offer to give a lecture and did not give others enough time to prepare, which seemed impolite.

But he felt that he and Chen Muwu had cultivated a relationship for a morning, and the other party had to sell him a face.

Although I didn't prepare too much and didn't talk about any specific content, even if I stood on the stage and said a few words casually, it was better than not holding this lecture at all.

As long as Chen Muwu can stand on the stage, he will be a monumental figure, a role model for these students in the physics department and even the entire University of Berlin.

At a young age, he has made outstanding achievements in his own discipline, physics and some other neighboring disciplines.

If Chen Muwu was asked to shout a few more words to the hairy students in the audience on the podium in the auditorium, "If you want to succeed, go crazy first, rush forward regardless of everything", "Fight once, get rich for three generations, and work hard not to fail", then for these students, the motivational effect is definitely no less than that of beating chicken blood.

Planck's fantasy is very beautiful, but the way he imagines this speech is definitely not suitable for Chen Muwu.

However, in a few years, Germany will have a master public speaker, and it will not only inspire the students of the University of Berlin, but directly inspire the non-Jewish people of all Germany.

As a result, Chen Muwu did not respond, whether he was going to hold a lecture in the physics department of the University of Berlin, and he killed an Einstein first halfway and denied his invitation on behalf of others.

Planck, who did not give up, turned his head to Chen Muwu, who had not yet expressed his position, but the latter only shook his head at him, with an apologetic expression on his face.

Originally, if he hadn't met Pauli and two other staff members of the physics department of the University of Berlin yesterday, Chen Muwu would not have visited here today.

In addition, the issue of unification theory with Einstein has not yet been discussed, and if Chen Muwu holds another lecture at the University of Berlin this afternoon, it is estimated that Einstein, who is starting to burn in his eyes now, will really have his own thoughts.

"I'm sorry, Professor Planck, but I did make an appointment with Professor Einstein this afternoon to discuss some issues. Besides, I personally didn't make any preparations for this temporary invitation, and I don't think I can say anything useful. Can't I be asked to give another lecture on "Relativity and Materialism" in Germany, the center of physics in the world? Not to mention that I will be laughed at by physicists all over Germany, I guess I will not be able to pass the level of Professor Pauli. ”

"Relativity and Materialism" is only a special product in a specific country, which is a small black spot that cannot be avoided in Chen Muwu's resume.

However, as long as Chen Muwu is great enough in the future, it shouldn't matter much.

Maybe the spearhead of the attack will instead point to the country that has been smeared alive and whipped again and again when it is dead, and ridiculed this country for being so great that a scientist as great as Chen Muwu will not be spared when he arrives in its territory to tell the content of a lecture with such a title.

I don't know if there will be someone else who will say this time, "Chen Muwu will stand up and toast when he comes"?

Smiles neither arise nor disappear out of thin air, they only move from one person's face to another's face.

Although this statement is modeled on the law of conservation of energy, although it is not science but just a funny way, after Chen Muwu refused Planck's invitation to give a lecture, he saw with his own eyes that Einstein, who was still sullen just now, had a smile full of approval on his face, and Planck, who was still looking forward to it just now, had Einstein's previous expression on his face.

Xiao Chen definitely couldn't make the physics seniors unhappy because of him, so after he rejected Planck, he added a few more words.

"I'm sorry Professor Planck, but it's a pity that I can't give a lecture at the University of Berlin, a historic institution of higher learning. If there is a chance in the future, I will definitely not miss it again.

"However, when I leave Germany, I may write another paper and send it to you, and I hope that Professor Planck will help me and publish it in the Annals of Physics."

Planck stepped down as head of the physics department at the University of Berlin, but he would remain editor-in-chief of the physics journal for a few more years.

Compared with the position of head of the physics department, the daily work of the editor-in-chief of the journal is much more leisurely.

He no longer has to participate in the management of the entire physics department, and only needs to read a few manuscripts a day.

Even though Chen Muwu has been a stable contributor to the Annals of Physics, it is inevitable that the Annals will be surpassed by the emerging Journal of Physics.

As a result, Planck had fewer and fewer manuscripts to review, and his work became more and more leisurely.

After promising a paper, Planck's face finally changed from cloudy to better, but it was not completely clear.

Chen Muwu didn't have to worry about what the topic of the paper was, Einstein had sent him a ready-made paper a day ago.

After leaving Germany, Gao and Low will also write a paper to prove why the transformation theory cannot solve the problem of the unified field, so as to completely dispel Einstein's thoughts, and let him quickly find a new way to continue gnawing this hard bone.

Chen Muwu felt that after his new paper was published, he didn't know whether Planck's face would reappear, but the smile on Einstein's face should have disappeared for a while.

After lunch, Einstein took over Chen Muwu's next trip at the University of Berlin from Planck.

The so-called itinerary just took Chen Muwu to his office, and then discussed with him the important matter of unifying electromagnetic force and gravitational force.

Although there is also an office in the school, because Einstein often went to the Kaiser Wilhelm Institute for Physics, this one at the University of Berlin is not used much, but it is still kept clean and tidy.

Regardless of whether the content is correct or not, Chen Muwu feels that the way he discussed problems with Einstein is much more comfortable than when he discussed problems with Bohr in Copenhagen before.

Even if Bohr's big smoking gun is extremely restrained from smoking in front of him because of his great respect for the rising star Chen Muwu, it is still difficult to change the official authority he cultivated after he became the director of the Institute of Theoretical Physics.

Bohr was notoriously grinding when discussing problems with others.

His habits of thinking and writing are gradually developed through discussions with students, assistants, or visitors.

Bohr writes articles by asking people to record their thoughts and inspirations every time they think of something, and then revise it repeatedly.

Because of this less flattering way of writing, his assistants changed one after another.

The last unlucky man, Kramers, was mentally ill by Bohr and was admitted to the University Hospital of Copenhagen, where he eventually left him.

Heisenberg, the current assistant, seems to be holding on well in Copenhagen so far, but after coming to the UK from Denmark and arriving at Cambridge University, even if Chen Muwu returned to China on leave, Heisenberg was still reluctant to leave the Cavendish laboratory, not just because of the freshness of just arriving in a place.

The only one who could cure Bohr was Dirac, who went straight to the point.

In the original time and space, after graduating from Cambridge University with a doctorate, Dirac first went to the University of Göttingen to meet Oppenheimer, and then parted ways with him, the latter went to Leiden, the Netherlands, and the former went to Copenhagen, Denmark.

It was Bohr who relied on his reputation among young physicists to attract a steady stream of free labor to the Institute of Theoretical Physics.

When Dirac got there, of course, he couldn't escape discussing physics with Pol, and by the way, he served as an assistant to record the bad luck.

No matter how good Dirac's personality was, he couldn't stand this kind of revising work over and over again.

Dirac, who was very irritated by Bohr, said this to Bohr after the outburst:

"Professor Bohr, when I was in middle school, my teacher taught me not to start writing until I understood the sentence."

But now with Chen Muwu, it is impossible for Dirac to leave Cambridge University after graduation, leave England and leave his homeland to wander around Europe.

As a result, the physics community has lost another famous scene, and no one can point out to his face how torturous Bohr's way of writing papers is.

In their offices, Einstein and Chen Muwu discussed the issue of unified theory for another whole afternoon, but still nothing useful came out.

In other words, it is the strangest thing to be able to produce results, Chen Muwu has always been accurately controlling the score, and he pretended to understand with a fool in his stomach.

But today's Einstein is different from yesterday's.

He didn't show any anxiety now, even if Chen Muwu was leaving Berlin tomorrow, and the two of them still didn't know anything about the study of the unified theory.

Still having dinner in the cafeteria of the University of Berlin, Einstein did not invite Chen Muwu to continue to fight with him in his office at night, but told Chen Muwu to rest as soon as possible after he went back, and he would visit the hotel again during the day tomorrow to continue to discuss this problem that bothered him.

Chen Muwu vaguely felt that Einstein's performance today was a little strange, but he didn't take it to heart.

Perhaps Einstein also gradually felt that this transformation theory may be a bit unreliable to explain the unified theory, right?

Walking back to the hotel where Oppenheimer lived, before going upstairs, Chen Muwu specially asked the front desk if they had bought the train tickets to Paris tomorrow.

If you haven't bought it today, you may not be able to buy it tomorrow.

The receptionist gave a satisfactory reply, saying that the ticket had already been done, and that Mr. Einstein had paid for it, and that they did not need to pay any additional money.

Yo ho! Einstein did this very well, and even paid for the ticket for them.

When we meet tomorrow morning, I'll have to say a few words of thanks to him.

Oppenheimer also praised Einstein to Chen, after all, he had been with Einstein when Chen Muwu and Planck were catching up in the department chair's office this morning.

He recounted to Chen Muwu in detail all the experiences he had had in Einstein's office today, including how he had discussed the unified theory with him, and under his own inspiration, Einstein thought of those novel ideas.

In the end, Oppenheimer even had a grateful look on his face:

"Dr. Chen, Professor Einstein is such a good person! He praised me for my good study of relativity today, and said that after I graduated from Cambridge University, he would help me see if I could be offered a teaching position at the University of Berlin, but it was just ......."

"Just what?"

"He said he wanted me to dig you up with you to the University of Berlin."

Chen Muwu was really speechless after hearing this.

Einstein and Oppenheimer discussed the theory of unity with great relish, which is strange enough.

It would be a bit whimsical for him to want to recruit himself by poaching Oppenheimer to the University of Berlin.

"Robert, do you want to teach at the University of Berlin?"

Chen Muwu did not respond to Oppenheimer, but asked rhetorically.

"Well, of course, I would like to find something good for myself before I graduate, and many universities in the United States have sent me invitations to teach, but in Europe, the University of Berlin is the first. As you know, American universities are not as good as those in Europe in terms of teaching level and prestige, so I was very excited to hear Professor Einstein bring this up. But if you hadn't stayed in Berlin, I wouldn't have come. ”

Seeing that Chen Muwu's expression was a little serious, Oppenheimer explained a little hurriedly.

"It's okay, it's okay, I'm just asking. If you want, you can also become a teacher in Stockholm in the future. ”

"That's great, I'm willing to go to Sweden, Dr. Chen!"

Regarding the question of Oppenheimer's future whereabouts, Chen Muwu did not understand it for the time being.

If he had not returned to the United States and had followed himself to Sweden, he might not have been able to lead the Manhattan Project.

There is another thing, since he has already come here, is it necessary for the first country in the world to grow mushrooms to be the United States?

With this question, Chen Muwu lay on the bed and fell asleep.

The next day, their last day in Berlin, Einstein arrived at the hotel where they were staying.

Chen Muwu was also very cooperative with this senior as he had done in the previous two days, and still coaxed him to discuss the unified theory for more than half a day.

Today's Einstein is even more abnormal, and even took the initiative to stop the discussion with Chen Muwu.

He looked at his watch, squinted his eyes intimately and smiled, "Chen, in half an hour, you are almost about to leave." It will not be too late for us to discuss this issue in the future.

"In this case, you pack your bags first, and I'll wait for you downstairs. When I was ready, I got in my car and went to the train station together. ”

Chen Muwu felt that Einstein might really feel that there was something wrong with his theory, so the discussion in the past two days ended faster and faster.

Since the host was reluctant to say any more, Chen Muwu was also happy.

After packing up with Oppenheimer, the two of them went downstairs and took their train tickets to Paris, France tonight from the front desk.

Einstein not only spent a lot of money to buy the two of them the fastest train, which only took a little more than one night to cover the more than 1,000 kilometers from Berlin to Paris.

Not only did he send a car and a driver, but he also accompanied the two guests to the train station as he did when he came.

Chen Muwu, who got out of the car, was ready to say goodbye to Einstein and politely thanked him for the meticulous hospitality he had prepared during the three days in Berlin.

But something surprising happened again.

Einstein didn't know where to conjure up a suitcase, and nodded to Chen Muwu with a smile.

"What do you mean, Professor?"

"Marie Curie's children are getting married, and if I don't know about it, I don't know, but now that I know, I have to go to Paris to say hello to my old friend! Also, Chen, we have a few days before the wedding to be able to continue chatting about the previous topics. ”
