Because of its proximity to the University of Berlin, this bistro resembles the one von Neumann invited to steak when he went to Cambridge University.

Even Chen Muwu, who became famous at a young age, is no different from ordinary people in the eyes of the waiters at that restaurant.

The waiters at the hotel at the University of Berlin have long been accustomed to having all kinds of people discussing all kinds of problems inside.

The middle-aged and elderly men in the diners, who are unremarkable, balding, wearing thick glasses, and wearing pleated suits, may be some professor, expert, or scholar from a nearby university or research institute.

But unlike the Cambridge University restaurant, the restaurant in Cambridge County basically only serves the teachers and students of Cambridge University, plus a small number of local residents who look down with them and don't look up.

The University of Berlin is located in Berlin, the capital of Germany, and in addition to the school's teachers, students, and nearby residents, there is also a large floating population.

In today's restaurant, in addition to the usual regulars, there are also new customers who pass by inadvertently, just in time to catch up with the hungry, so they casually walk in to eat.

It is indeed a pleasant surprise to see Albert Einstein, who often appears in newspapers with his words and photographs in such a hidden restaurant.

Even though most people don't like to see this great Jewish physicist in their usual daily chats, it was when no one had ever met him in their lives.

After meeting each other, the feeling in my heart is something else.

It is not an honor or an honor to be able to dine in the same restaurant as the best physicists in the world today, but it can only be said that no one else wants to have this opportunity.

It's a pity that there is no mobile phone and no network, so I can't take out photos, videos, and send X ins.

So I had to wait for the waiter to pass by my table the next time, borrow him a pen and paper, and ask Dr. Einstein to sign it for him when he finished his meal and was ready to leave.

Yet, yet.

Before the waiter arrived, he saw a young student walking straight to Einstein's table, looking like a greeting, but he refused to leave after standing for a long time.

Dr. Einstein was also kind enough to say something to the young man.

No one expected that at the end, the young man suddenly raised his voice,

Although I can't understand any "transformation" or "affine theory", I can still see the commanding look of his speech, and the mockery in his tone can still be understood.

What grade is this hairy young man who dares to reprimand Einstein to his face?

It's just this table in the center of the storm, and I don't know what the other guests in the restaurant think of them now.

After Pauli expressed his disapproval of the unified theory, Einstein was eager to find out why the future head of the physics department at the University of Berlin would think of him.

So, after asking the two guests for their opinions, he invited Pauli to sit down and eat at the same table with them, and chatted with them.

Chen Muwu has no objection to this, looking at today's situation, it is estimated that Pauli will discuss his unified theory with Einstein all night, and the fire of war will not easily burn to himself.

If Einstein is willing to pay more money to invite someone to dinner, it is also his business, and it has nothing to do with him.

In any case, Germany has gradually come out of the economic crisis caused by various reasons such as the defeat in World War I, and the purchasing power of the mark has long since recovered.

Take 10,000 steps back, even if Einstein is unwilling to pay for it, it is not impossible to help out with the money himself.

Oppenheimer was reluctant in his heart, but since Chen Muwu had no opinion, he was embarrassed to say anything more.

At this table, he is the one with the lowest academic status.

Although he looked down on Pauli, he was an associate tenured professor at the University of Berlin.

A Chinese proverb says that the dragon that rides the wind and waves in the sea is teased by small shrimp on the shallows, and the tiger that dominates the tiger in the deep mountains is bullied by the puppies on the flat ground.

Oppenheimer felt more and more that he was the dragon, the tiger, who happened to be born in 1904, according to the zodiac sign, he belonged to the dragon.

The traditional culture of China is really broad and profound.

Pauli sat down, and the two colleagues who were invited to Pauli's banquet today could only sit down with him.

They are all faculty members of the physics department of the University of Berlin, and their relationship with Einstein is not too good or too close, but they always bow their heads in the department every day without looking up.

What really surprised these two people was Chen Muwu who appeared at the table.

They also read in the newspaper about Dr. Chen's unwarranted disaster in Poland, but no one expected that Professor Einstein would be able to cut off Dr. Chen's beard at the Berlin train station and invite him to the University of Berlin.

It is a well-established fact that German food is much better than British food.

Oppenheimer felt that the dishes on this table seemed to be somewhat similar to the dishes he had eaten at the banquet in Fengtian's Zhangfu.

Although it is not as exquisite as the latter, after all, the price and environment are there, but the cooking techniques and taste of the ingredients are the same as the Northeast cuisine in China.

As for the matter of eating, Chen Muwu is pessimistic.

The food in Germany is decent, and you can eat delicious meals for more than ten days in France.

After leaving France and returning to England, endless torture awaited him.

At the dinner table, the Germans Albert Einstein and Pauli had no special feelings about their meal tonight.

For them, it's just a daily routine, and they've long been accustomed to the taste of their homeland.

These two men devoted all their energies to the controversy over the theory of unity.

The public said that the public was reasonable, and the mother-in-law said that the mother-in-law was reasonable, and neither of them could convince anyone, so they could only find a third person outside the field to comment.

The third person, Chen Muwu, could only eat on the side and play Tai Chi at the same time.

He had to sigh at how terrible Pauli's intuition in physics was.

For a while, although he could not say what was wrong with Einstein's transformation theory, he insisted that the electromagnetic force and the gravitational force could never be united, and that there might be a third force in addition to these two forces.

Hear Pauli's novel argument in order to disprove Einstein's theory.

Chen Muwu, who was eating, was stunned, and the black bread he was chewing in his mouth was also stuck in his throat.

"Chen, what's wrong with you?"

The host, Albert Einstein, was a little lost in the verbal exchange, so he chose to avoid the battle and turned his head to care about his guests.

"No, it's nothing......"

Chen Muwu also picked up the wine glass in front of him, and Einstein's glass of non-alcoholic punch opened up a new idea for him.

So he also followed suit and ordered a glass of zero-alcohol punch, but in apple flavor.

Chen Muwu took a few sips of apple juice, soaked the piece of black bread stuck in his throat, and finally swallowed it.

"I think Professor Pauli's point of view is a bit interesting, after all, we still haven't figured out which of the electromagnetic or gravitational forces in the nucleus holds together those positively charged protons that are repulsive to each other. Maybe it's neither, but there really is a third force......"

Pauli was surprised, he didn't expect that the Chinese man who he thought in his heart must not deal with him would actually stand on his side this time, agree with his own point of view, and speak for himself.

Just seeing that the smile on Einstein's face disappeared, and the wrinkles between his eyebrows were a little more, Chen Muwu, who had a glass of wine, could only continue to change his words and said: "However, even if there is a third force, maybe this third force can still be unified with electromagnetic force and gravitational force."

"In the absence of a third force, I think it would be useful for Professor Einstein to try his way of thinking, first find a way to unify electromagnetic force and gravitational force, and then wait for the third force to be discovered, and then apply this method to it."

I knew it, I knew it!

Pauli secretly complained to himself, and the good impression of Chen Muwu that had just sprouted in his heart was gone.

This technique of praise and disparagement is used so skillfully, it is worthy of something that only his lifelong enemy, Chen Muwu, can do.

In fact, Chen Muwu never agreed with Einstein's ideas, but he just didn't want to ignore it like Pauli, go straight to the point, and inadvertently hurt other people's hearts with words, but he didn't know it himself.

Hearing Chen Muwu speak for him, Einstein at the table may have been very happy for a while.

But if Einstein thinks about it after he goes back, he can figure out what is wrong with this.

There are sixteen independent components, and gravity alone accounts for ten of them.

The remaining six, the force assigned to the electromagnetic force at the beginning, may be okay, although it is not equal to the number of gravitational forces, but it is still reasonable.

But what if there really is a third force?

It doesn't make sense that the electromagnetic force and the third force together grab six indicators, but gravity dominates the other ten.

Chen Muwu just said it very vaguely, not as unsentimental as Pauli, what he thought was that at least he had to finish today's dinner well.

After all, as soon as he got off the train, he was stopped by Einstein to discuss the problem, he didn't eat breakfast, he didn't eat lunch, if he didn't eat well at dinner, Chen Muwu really wanted to shoot the case.

When the meal was finally finished, Einstein had settled the bill, and Pauli led the two guests he had invited to leave.

Einstein meant to continue to go to Chen Muwu to talk about his reunification, but Chen Muwu politely refused on the grounds that he was tired from the journey, that the coming day was long, and that it was not too much time.

Thinking that Chen Muwu had been grinding for a whole day today, although he was reluctant, Einstein could only leave temporarily.

Oppenheimer said that he wanted to go to Berlin for a walk, but Chen Muwu just wanted to beg him to let him go.

The exhaustion of the journey is really not the reason why Chen Muwu rejected Einstein, but his current true state.

And after such a long trip, it is estimated that the eldest young master's heart has long been restless.

He said that he would go for a walk in the city, and it was estimated that the last place he would go to would be either a bar or a dance hall.

Anyway, after sending Oppenheimer away, Chen Muwu, who had taken a bath, fell asleep on the bed.

When he opened his eyes again, it was already dawn the next day.

I don't know what time Oppenheimer finished his game life last night and returned to the hotel, Chen Muwu decided to go for breakfast first, and then come back to wake him up and wait for Einstein's arrival.

As a result, as soon as I arrived at the restaurant on the first floor, I found that the other party was already sitting at a table waiting for me.

Einstein's expression seemed a little unpleasant.

Could it be that after the separation last night, he had already thought of the irrationality in his changing views?

"Chen, how did you sleep last night?"

"Thanks to you, Professor, this is probably the most restful sleep I've ever had on the way back."

"But I didn't sleep well," Einz said with a helpless expression on his face, "I should have stayed last night to continue discussing with you, and as soon as I got home, I was notified that the physics department wanted you to go to the University of Berlin for a walk." ”

Oh, and that's what made Einstein sullen.

He felt that the visit to the Department of Physics had delayed the discussion between him and Chen Muwu, and that Dr. Chen had only stayed in Berlin for three days.

And the reason why Einstein confessed this matter to Chen Muwu was that he hoped that he could refuse the invitation of the physics department, and then discuss the reunification plan with himself.

Physics departments are similar all over the world, and Chen Muwu can refuse invitations to visit other schools, but not the University of Berlin.

No way, Planck, the head of the physics department at the University of Berlin, was kind to him first.

Even if Einstein sent a telegram to recommend it, if Planck, as the editor-in-chief of the Annals of Physics, had not made a decision, Chen Muwu's first paper would not have been published in the top journals of European physics so easily.

As early as three years ago, in 1924, when Chen Muwu followed Rutherford to Brussels to attend the Fourth Solvay Conference, he wanted to visit Germany with the French physicists led by Langevin after the conference.

It was only because Rutherford urged him to go back to Cambridge to do experiments and prepare for his doctoral dissertation, so Chen Muwu did not make the trip that time.

This time, he was finally able to meet Planck's old man before he retired and expressed his gratitude in person, and Chen Muwu said that he would not miss the opportunity.

So he pretended not to see, and Einstein, who had been waiting for him to make a statement, hastily finished dinner, and then went upstairs to call Oppenheimer.

He also asked Oppenheimer to take out two packets of tea from his luggage that he had brought from China as a gift for meeting Planck.

- The reason why I didn't send Einstein yesterday was because he didn't even drink coffee with caffeine.

Oppenheimer, who had just woken up, found the tea leaves and dressed himself quickly at the speed of light.

When he walked out the door still dressed like a rich man, Chen Muwu saw something on Oppenheimer's neck that had never appeared before - a camera.

Although Chen Muwu is not very interested in photography, he does not study the camera.

But he still saw the classic five letters on the lens cover, "Leica".

A trip to Berlin, can Oppenheimer still find this kind of treasure?

Although I don't remember when the Leica brand was founded, Oppenheimer bought this one, which should be one of the company's early models.

In the future, it can be regarded as an antique, and Chen Muwu feels that he should also buy one to play with, not because of its appreciation in the future, but so that he can take more photos to record history.

"Robert, you're got a good camera! How much did it cost? ”

"Not bad, right? I think it's good too! Wandering the streets of Berlin last night, I suddenly wanted to buy some local souvenirs, so I entered the department store building. I picked and chose such a German-made camera. Unlike those bulky goods in the United States, this small and delicate camera, the more I look at it, the more I like it. It only cost a small amount of money, and if I had a camera before I went to China, I don't know how many photos I could take along the way. Alas, what a pity. ”

Anyway, as long as he didn't buy the world's tallest building, Woolworth Building, it was not a lot of money for Oppenheimer, a rich boy.

Chen Muwu, who couldn't ask the price, could only give up and took Oppenheimer to the restaurant downstairs to meet with Einstein.

On a whim, Oppenheimer asked Chen Muwu to stand side by side with Einstein, and the first photo taken by his camera recorded the excited Chen Muwu and the sullen Einstein.
