Say Einstein, and Einstein will come to the door.

In addition to Bohr and Heisenberg, he also sent a letter from Berlin during the time when Chen Muwu was out to play.

Since he returned to Germany from Sweden last summer to reconnect with Chen, the correspondence between the two has not stopped.

Apparently this time, Einstein must have met Langevin and de Broglie in Berlin, and also received the letter sent to him by Chen Muwuto.

In the letter, Einstein gave another big compliment to his Chinese genius.

Einstein saw Chen Muwu's paper on the use of electron diffraction to verify that electrons have waves, and praised his idea that all matter is wave.

Einstein also said in the letter that he had recently calculated and analyzed the quantum ideal gas according to the new statistical method proposed by Chen Muwu, and found that the pressure of the quantum ideal gas also came from two components, namely particles and waves.

He intends to publish this paper, which, to a certain extent, will also illustrate the self-consistency between the two theories, Chen and Chen.

Chen Muwu always felt that Einstein's title in the letter was a little strange.

Well, the English name "Chen Wave" is fine.

But after translating "Chen Bo" into Chinese, Chen Muwu always felt that there was something too wrong with this word.

After he obtains his doctorate, he must not let others call him "Chen Bo".

If you find an opportunity in the future, you must clarify to the physics community that there is no problem at all in naming other experiments and theories made by Chen Muwu with his surname "Chen".

It's just this matter wave, let's honestly call it "Matter Wave", don't call it Rausch Chen Bo!

Einstein also said in the letter that Langevin relayed to him the fourth quantum number of the atomic model and the theory of electron spin presented by Chen Muwu at the Solvay conference, and also heard some arguments between him and Lorentz over whether the electron spin would violate the theory of relativity.

It is true that he proposed that the problem of spin can be solved by adding classical theory and relativity, but he always feels strange to use this method, and perhaps the spin of electrons does not really rotate like the earth.

Einstein finally comforted Chen Muwu that it didn't matter if he didn't go to Germany to meet this time, after all, graduation is the top priority he is facing now, and there is still time to meet in the future, so it will not be bad this time.

Einstein's letter is long enough, and after the end, there is one more.

He said that the new acquaintance, Louis, the younger brother of the Duke of de Broglie (Maurice), who had come with Langevin, was also a very interesting person.

Chen Muwu said in his heart, De Brogyi is not only interesting, he will also be the pioneer of your old love account in the future.

If the talented Copenhagen School is compared to Cao Wei, then Einstein is Shu Han, and he is supported by Prime Minister Ai alone.

He had only two well-known men under him, one was Schrödinger and the other was De Broglie.

Einstein continued in the letter, these days Louis often praises you in front of him how smart Chen Muwu is, and also taught him how to play mahjong.

This brain game from China is really interesting!

……

In addition to the letters from the two physicists, Chen Muwu also received a large envelope from the organizers of the Solvay Conference.

The envelope contained a group photo of the Solvay Conference, as well as the group photos that Chen Muwu had asked a photographer to help him take with others, as well as a group photo with Eve with the big tree as the background.

Chen Muwu took out the photos and browsed them one by one, then put them in an envelope and prepared to take them back to Mrs. Brown's house to pack up the group photo of the Cavendish laboratory last fall.

……

A Cavendish lab chatterbox, a math nerd, and an English literature gourmet, these three people can get together because Chen Muwu is a link in it.

After attending Ye Gongchao's master's thesis defense meeting at Magdalen College, the four of them got together for a meal.

Ye Gongchao's intention to leave the UK and go to France has been decided, Chen Muwu suddenly thought of a certain line in a certain song "Xintianyou", what is called Bai Huahua, what is the water spirit, such a good place can't keep you.

But then he thought about it, Cambridge University is really not a good place, basically either balding men, or not bald men.

And the name of Paris as the "romantic capital" has long been resounding all over the world.

Ye Gongchao has passed his twentieth birthday this year, and it is at the age of "having a man with spring".

It is understandable that he wants to leave the monk's temple in Cambridge and go to the outside world of flowers.

It's just that the key to this delicious delicacy is that you don't have to cook your own Chinese food, and now you don't have to eat one less meal.

A few days ago, the publishing house sent a sample book, and they wrote Chen Muwu's name in the author's column on the cover.

Chen Muwu just came up with an idea, and put forward a lot of revisions to the manuscript, and most of the rest of the writing work was written by Ye Gongchao.

Moreover, this gentleman is not used to typewriters like Chen Muwu, and all manuscripts are written letter by letter on the manuscript paper.

He revised it several times, and finally copied it cleanly, which was a lot of work.

Erasing the fruits of other people's labor like this, Chen Muwu really can't bear it.

So he took the opportunity of eating and asked Ye Gongchao with a sample book: "Gongchao, what name should you use for the author of this book?" ”

Ye Gongchao thought for a while and said: "Brother Hanchen, it's better to name the protagonist in the book George Chen, you and I each have a name." My surname is Ye, and I start with Y, so I'll just say 'York'. ”

"Then I'll say 'Chandler' and use this Chandler York as our pen name, why not?"

The Chandler selected by Chen Muwu is not from the TV series "Friends", but from a mystery writer he prefers, Raymond Chandler.

"That couldn't be better." Ye Gongchao also likes this name very much.

When Chen Muwu put down the book and planned to continue eating, this book "Murder on the Paris Express" naturally couldn't escape Capitsa's clutches.

"Chen, did you write this book? You see, there's your name on it. However, what publishing house is Penguin Publishing? How come I've never heard of it before? Oh my God, it's still a book! ”

At first, Chen wanted to propose that the publishing house be called Panda Press.

But then he looked for information and found that there are basically few Westerners who have seen live pandas.

If the name is called Panda now, Chen fears it could lead to more poachers sneaking into China's hinterland to hunt the rare animal on a large scale.

So in the end, the name that the publishing house finally finalized was still Penguin.

As soon as he read the beginning, Kapitsa was completely attracted to the content of the book.

Because the journey of the protagonist in the book, George Chen, is the story of taking a train from his own country and taking a train to Europe, which makes him have a strong sense of resonance.

In fact, when Chen Muwu and Ye Gongchao were writing the book, they also asked Kapitsa a lot of things, but he didn't notice it at the time.

Kapitsa saw it with relish, and Ye Gongchao also left the table and ran to the kitchen to see if the soup in the pot was stewed.

At this time, Chen Muwu set his sights on Dirac, who had been silent since eating.

"Paul," after getting acquainted with everyone, especially Kapitsa, Chen Muwu could finally stop calling him Mr. Dirac, but by his first name.

"What have you been up to lately? I have a little problem here, would you like to try it? ”

With the "help" of his mentor Fowler and his roommate Chen Muwu, Dirac's research direction was finally pulled from the theory of relativity to the microscopic level in the atomic nucleus.

In this world, there is now one more person who is sad that students have been snatched away by new disciplines.

Oh, it turns out that this man is still Eddington, so it's fine.

The number of grieves has not increased, and the world remains the same as before.

Chen Muwu's so-called small topic is the problem that Heisenberg mentioned in his letter a few days ago that the g-factor should be 2.

Compared with other physicists who focus on experiments, Dirac, who graduated from the Department of Mathematics, has a solid theoretical foundation, and maybe he can really use the theory of relativity to find a solution to the problem of factor 2.

And the reason why Chen Muwu suddenly asked Dirac to try this question was to make up for the sense of indebtedness in his heart.

That's right, although the final defense of the doctoral dissertation will not be carried out until three or four days later, now, Chen Muwu has begun to calculate in his heart what to write for the next thesis.

This time, he plans to finish his work, publish three wave equations in one go, and write a paper that is dozens of pages long, and he can't always let others call him short and concise.

Of course, one of these three wave equations is the Dirac equation that Dirac once derived.

After more than a year, he did several experiments and published several theories, but Chen Muwu never attacked the good brothers around him.

But this time, if you want to completely establish quantum mechanics, then the Dirac equation is a hurdle that Chen Muwu cannot bypass no matter what.

That's why he felt a little sorry for his good brother, and wondered if he could compensate Dirac in other ways.

After listening to Chen Muwu's description, Dirac was really attracted.

Because whether it is the theory of relativity, or the electrons outside the nucleus, he is very interested in the content.

But after thinking about it for a while, he said with some embarrassment: "Chen, I may not have much time to think about your question now, because the final exam is coming soon, and I may have to devote myself to revision in the next period of time."

"But don't worry, when the exam is over, I will immediately ask you for information to see if I can use the theory of relativity to solve the problem you raised."

"No problem."

This problem, and the solution to this problem within the classical framework, has been told by Chen Muwu to Heisenberg, who is far away in Germany, and Dirac, who is close to him.

Now we have to see who of these two peers whose birthdays are only more than half a year apart will solve this problem earlier and become the smarter of the two smart people.
