Chen Muwu feels that since this spring, he has basically had no time to spare.

At the beginning, he originally planned to take a break after completing the electron diffraction experiment and give himself a good vacation.

Then, Chen Muwu was next door to the electron diffraction laboratory and met Stoner, who was doing electron number experiments outside the nucleus.

There's no way, you can't do without the merit of sending it to the door, right? He could only tearfully accept Chen's incompatibility principle.

Since we chose to announce Zen's incompatibility principle to the physics community in a speech at the Solvay Conference, it would not be too much to propose that electrons have spin to provide a theoretical explanation for this incompatibility principle, right?

Just after that speech, Chen Muwu happened to meet the cat abuser Schrödinger.

When he saw Schrödinger, he was afraid that others would come up with the wave equation first, so he could only grit his teeth and figure out the wave equation.

After quantum mechanics had been initially established, and the papers on matrix mechanics and wave dynamics had been finally published, Chen Muwu thought that he could finally take a break this time.

As a result, Dirac first came to the door, "found" the contradiction between Chen's statistics and Chen's incompatibility principle before him, and made another Dirac-Chen statistics in quantum statistics.

Immediately afterwards, Einstein sent him another letter, forcing Chen Muwu to put forward the uncertainty principle and confront this stubborn old man.

In the nine months of this year, Chen Muwu has published more academic results than in the whole of last year, even if he wasted more than a month to prepare for and participate in the Olympics.

In the past nine months, he has advanced the historical progress of modern physics by three full years.

Whether it is the uncertainty principle, the Dirac-Chan statistics, or the electron diffraction that finally proves the wave nature of the electron, these all appeared in the original space-time, but they all appeared in 1927.

Chen Muwu always felt that there was an invisible hand in the dark, just like the boiling sheep behind the Pleasant Goat, always pushing himself forward behind his back.

……

Chen Muwu always felt that he was very tired and hard, but he didn't know that the theoretical physicists in the world were more tired and harder than him because of a few papers.

And the root of all evil is him Chen Muwu himself.

Before most people could understand why the wave function in the wave equation was a probability wave, Chen Muwu published a new principle of quantum mechanics in the Annals of Physics.

The experimenter's knowledge of quantum location limits their knowledge of its velocity at the same moment.

In the face of this condescending sentence, most people's first reaction is that they don't understand it.

But once they read the paper through and understood what the uncertainty principle was, they understood that the proposer of this principle, Chen Muwu, had gone one step further from matrix mechanics and completely abandoned the existence of electron orbitals.

In his reply to Einstein, Chen Muwu mentioned the uncertainty principle for the first time, which completely angered the German physicist.

He believes that Chen Muwu has not only lost his way back, but has to make inches, and his behavior can be regarded as an academic "declaration of war".

Einstein, of course, did not agree with the idea of the uncertainty principle, so he went to the reporter of the Berliner Zeitung and sent them interview material: "From the very beginning, I did not agree with Bohr's correspondence principle, and therefore did not agree with his statement that the laws of physics behave differently at the macroscopic and microscopic levels.

"Since physics is certain in macroscopic conditions, it should also be certain in microscopic conditions.

The uncertainty principle proposed by Chen Muwu only means that human beings cannot accurately predict and measure certain phenomena, but not that these natural phenomena are inherently uncertain.

"I'm looking for a more profound law that goes beyond statistical probability to refute his point, but it will take some time."

……

One of Chen Muwu's good friends, Dirac, who has been supporting the various theories proposed by Chen Muwu for a long time, also has his own views on the uncertainty principle.

Both had moved out of their rooms on the second floor of Mrs. Brown's house, and had seen each other much less than they had been before.

But Dirac still found an opportunity to come to the office of Cavendish Laboratory, meet with Chen Muwu, and offer him some of his opinions.

"Chen, the thought experiment you designed in your latest paper is indeed very subtle, and the derivation in it is indeed very rigorous, but I don't think that what you have obtained cannot exist as a physical principle.

"I may be offended by saying this in the Cavendish lab, although it is always said that physics is a science based on experiments, but I think that physics should be a discipline based on mathematics.

But the uncertainty principle you came up with is not an equation in mathematics, but only a description of uncertainty. The inequality you proposed may explain some physical phenomena, but this thing is not clear enough to me, and it is a bit vague. ”

Unlike Einstein, who used macroscopic classical physics to deny it, Dirac took a different approach this time.

Because he was an undergraduate in mathematics, Dirac tried to deny the uncertainty principle mathematically.

Chen Muwu does not plan to have an academic quarrel with this high-achieving math student friend in what he is good at.

Instead, he pointed out a different path for Dirac: "Paul, I don't have a very deep understanding of mathematics myself, but just yesterday another mathematician came here to talk to me about it.

"If you want to talk about physics, I'm welcome, of course, but if you want to raise it to the level of mathematics or philosophy, then I urge you to go to the Cambridge Observatory and talk to Mr. Eddington."

……

The reason why Chen Muwu mentioned Eddington was because the other mathematician who came to him yesterday was the director of the observatory.

Eddington had come to Chen Muwu once before, asking him for authorization to write a popular science article on the matrix and wave theory of quantum mechanics for the public.

Unlike Dirac, who visited today, Eddington highly praised Chen Muwu's new uncertainty principle, just as he did when he strongly supported Einstein's special and general theories of relativity.

He even excitedly said to Chen Muwu yesterday that "the uncertainty principle is a basic universal principle, and its importance seems to be comparable to that of the principle of relativity."

Chen Muwu did not expect that he had promised to let Eddington write a popular science article on quantum mechanics would be so highly praised by the latter.

You know, Einstein also became famous in the English-speaking world because of the introduction of his popular science articles.

Eddington had no nostalgia for the classical physical age, and he hated the determinism proposed by the French astronomical predecessor El Laplace.

Laplace once envisioned a highly intelligent creature called Laplace, who knew everything and could accurately tell the position and speed of each object in the universe, so he could predict the trajectory of each object in the universe according to Newton's laws of motion, and could deduce the history of the entire universe and the future development trend from it.

Unlike Dirac's suggestion that "physics is a discipline based on mathematics", Eddington believed that mathematics was nothing more than a tool in the service of physics.

Mathematicians should take their responsibilities more seriously than indulge their preference for arithmetic symbols.

Chen Muwu introduced Dirac to Eddington, who had a different opinion from him, and he didn't know who could convince whom between the two in the end.

……

Rutherford was still not interested in Chen's theories, but he was happy to see his students deflated the world's leading physicists.

I never step into the laboratory, and my daily work is to sit at my desk, use the paper and pen in my hand to sit and talk, and now I finally eat back, right?

Does the electron orbital exist or not? Is the wave function in the wave equation a probability wave?

Quarrels in physics journals and newspapers alone will not solve this problem.

If you want to prove the truth of the concept, you have to go back to the laboratory after all.

Although the current technological means cannot explore the truth, the optimistic Rutherford believes that as human technology becomes more and more sophisticated, one day, everyone will find the answer to the question.

But at the same time, Rutherford had some faint worries in his heart, that is, his student Chen Muwu, might be more suitable for him to engage in theoretical research than to stay in Cavendis's laboratory to do experiments.

……

Rutherford shared the same view as Bohr, another of his belovers.

After experiencing the betrayal of his younger brother Chen Muwu on the atomic model, Bohr was indeed depressed for a while.

But with the help of his new assistant Heisenberg, he soon accepted the quantum mechanics proposed by Chen Muwu.

After reading Chen Muwu's latest paper on the uncertainty principle in the Annals of Physics, Bohr always felt that his idea was familiar, as if he had seen it somewhere.

This question bothered Bohr for a day or two, until he was in his study and found the first reply letter that Chen Muwu had sent him last fall.

Bohr looked at the hand-drawn circular pattern on the reply and fell into deep thought.

His heart once again overflowed with love for talents, and he felt that Chen Muwu was really unfathomable, this kind of person could no longer stay in the Cavendish laboratory and waste his youth, and he had to dig into the Institute of Theoretical Physics.

It's just that Bohr thought that his invitation not long ago had just been ruthlessly rejected by Chen Muwu himself, on the grounds that he still had the task assigned by Rutherford in the laboratory, and he really couldn't leave.

So this time he simply took a different approach and wrote the invitation letter to his teacher Rutherford.

……

"Dear Teacher,

"After reading several of Dr. Chen's papers recently, I was fascinated by his wit and profound insights into physics. His knowledge and understanding of theoretical physics far exceeds that of a regular graduate student, and I am confident that his talent and talent will be an important contribution to the field of theoretical physics in the future.

However, in the Cavendish lab, he was pushed in the direction of the lab. Although he has also shown outstanding experimental ability, I believe that he should concentrate on delving into theoretical physics instead of wasting time on experiments. As a teacher and mentor, you know this too.

"Therefore, I intend to invite Chen Muwu to work at the Institute of Theoretical Physics at the University of Copenhagen in Denmark. Our team is conducting some challenging and meaningful research, and we are confident that his inclusion will have a positive impact on our research. At the same time, we are willing to provide him with a good working environment, resources and support to ensure that he can succeed.

"I very much hope that Muwu Chen will join our team to carry out meaningful research with us and make greater progress in the field of theoretical physics.

"Heartfelt regards,

"Nils Bohr"

After reading the letter on the couch in Rutherford's office, Chen Muwu cautiously raised his head.

He could not see any emotion on Rutherford's face, and therefore could not guess what his teacher was thinking.

What exactly did he mean by showing himself the letter?

Do you want to ask yourself for your opinion on Bohr's re-invitation, or is it just a loyalty test?

However, Bohr was so bold that he dared to say directly to Rutherford in his letter that theory was much more important than experiments.

Seeing that Chen Muwu raised his head, it seemed that he had finished reading the letter, so Rutherford opened his mouth and asked what his students thought.

"After you turned down Nils last time, he actually wrote an invitation to me this time.

However, he wrote in the letter very politely, and actually said that doing experiments was a waste of time. Probably this is true for him, after all, he is Bohr, and like you, he is the best student I have ever taught.

"Chen, have you changed your mind about Bohr's second invitation now?"

Chen Muwu had previously rejected Bohr's invitation because he wanted to stay at Cambridge University and wait for the arrival of Zhao Zhongyao and Shi Ruwei.

But now it is different from the past, Chen Muwu feels that he can go to Denmark for a trip, so he should put down his work and go to Northern Europe to relax.

Hearing that Rutherford's tone was still as relaxed and happy as usual, Chen Muwu realized that the teacher didn't mean to be angry at all.

At the same time, he finally determined that Rutherford was indeed asking him for advice.

So Chen Muwu cautiously said his true thoughts: "Uh, teacher, if I can, I want to go to Copenhagen, it's not impossible." ”

"Well, since you have this will, then I can't keep you.

"Write an application after you go back, and I'll ask James to go through the process for you according to the procedures for a business trip."

With £10,000 a year, Rutherford also became wealthy.

A year ago, even Rutherford, the director of the Cavendish Laboratory, would only consider travel to the outside world if the conference provided round-trip travel expenses.

Fowler is the only one in the entire laboratory who can travel at public expense every year without worry.

However, his funding source is not the Cavendish laboratory, but the mathematics department.

"Thank you, teacher."

Rutherford struggled in his heart for a moment, and then continued: "Chen, I want to know, what do you think of experiments and theories? ”

"If, like Bohr, you feel that theory is more important than experiments, you don't have to leave the Cavendish laboratory to study theories, go to Denmark, stay at Cambridge University, and still study theories as you like.

"I can help you apply for the position of Lucas Chair Professor of Mathematics, or I can create a new professor of theoretical physics in the Cavendish Laboratory."

Lucas Professor of Mathematics?

This is truly a remarkable position, and it can be called the greatest position in the whole of Cambridge University.

It's not that this professor has much power, but because the second Lucas professor of mathematics was chosen by one of the greatest physicists in human history, Isaac Newton.

In order to keep Chen Muwu, Rutherford actually opened such a big bargaining chip.

In his heart, he seemed to be very afraid that Chen Muwu's trip to Denmark would never return, and he would stay there to study physical theories.

He had already lost one Bohr, and Bohr must not be allowed to abduct another theoretical genius.

Chen Muwu also heard Rutherford's meaning from the words.

He laughed secretly, his teacher was really careful.

First of all, he certainly won't leave the arms of experimental physics so early, after all, there are still so many particles waiting for him to discover.

Secondly, even if he wanted to study theoretical physics, Chen Muwu did not plan to send someone to the fence, not to mention, that person was Bohr.

It's okay to be friends with him, but it's okay to be a superior...... That's better not to.

Moreover, he was really moved by the conditions that Rutherford had promised.

Although I can't meet Newton, if I can inherit his mantle, isn't it also a kind of affirmation of myself?

So he comforted Rutherford: "Teacher, please rest assured, I won't be going for too long, probably only for about a month or two, and it shouldn't delay the development of the electron microscope too much." ”

Oh, and there's the electron microscope.

Rutherford felt that the electron microscope in Chen Muwu's mouth was even more unreliable than the "wolf is coming" in the fairy tale, and he didn't know the year of the monkey to see the finished product in the Cavendish laboratory.

If you really can't do it, let someone else take care of it.

"That's great, I'm at Cambridge University, waiting for you to come back for Christmas."

Hearing Chen Muwu's promise, Rutherford put down his hanging heart a little.

Although he complained about Chen Muwu in his heart because of the electron microscope, he still had a smile on his face.

……

Now that he has decided to leave for Denmark, there are still a lot of bits and pieces waiting for Chen Muwu to do before leaving.

The first is to "arrange the aftermath".

He's gone, but what about the three students under him?

Will they take it with them, or will they entrust it to someone else for the time being?

After some careful consideration, Chen Muwu finally decided to leave Zhao Zhongyao and Shi Ruwei behind, entrust them to Kapitsa, who also belonged to the Cavendish Laboratory and Trinity College, and take Oppenheimer to Denmark by himself.

It wasn't that he was biased in making this decision.

On the one hand, it was because with further contact, Chen Muwu learned that in order to send his favorite students abroad, Ye Qisun actually let Shi Ruwei, who was supposed to graduate from his bachelor's degree in 1925, graduate a year early.

One year less study time has led to him being slightly inferior in terms of knowledge.

It is much more beneficial to have two people stay in Cambridge to learn the basics than to take them to Denmark for a sightseeing trip.

On the other hand, it's because Oppenheimer was too prickly.

Oppenheimer and Rutherford looked at each other unpleasantly.

Chen Muwu was afraid that if he left, Oppenheimer who stayed at Cambridge University would do something earth-shattering.

After confirming the personnel, Chen Muwu took Oppenheimer to London to apply for a visa at the Danish Embassy in the United Kingdom.

When Zhu Zhaoxin learned that Chen Muwu was going to leave Britain for a two-month business trip to Denmark, he sent a telegram to the Chinese Legation in Denmark, asking Chargé d'Affaires Xu Zhaoxiong to take good care of him.

After all these things were done, Chen Muwu left Cambridge University with Oppenheimer.

They did not choose to cross the English Channel by boat from Dover and then overland from France to Germany and then to Denmark.

Instead, they sailed north from Cambridgeshire to Norwich, from which they crossed the North Sea to the Danish port city of Helsingør.

Several times this year, Chen Muwu has crossed the English Channel by boat, and Chen Muwu has not felt unwell once.

So he began to be very confident in his physical condition, and felt that his previous seasickness from Tianyu to Shanghai was just an accident.

However, the strong winds and waves on the North Sea did not make Chen Muwu stand on the deck and shout "let the storm come more violently" like Gorky's petrel, but directly shook him into doubt.

During the flight of one day and one night, Chen Muwu couldn't stop nausea and vomiting, and basically never got out of bed.

If he had known that this was the case, Chen Muwu would rather take a long detour to take a train than come to the sea to suffer this crime.

The next day, the ship docked in Helsingør, and Chen Muwu was stunned by Oppenheimer's backfall step by step.

Before he became the principal, he had already gained a Wang Yong.

The two spent the night in a local hotel in Helsingborg, and Oppenheimer was still the teacher who took care of him.

After resting for another whole day, Chen Muwu finally came back to life.

His mood gradually became happy, but he completely forgot that in the middle school Chinese class, when the teacher explained the role of environmental description, he had listed one point, that is, environmental description, which often also has the role of symbolism and suggestion.

Chen Muwu's trip to Denmark is destined not to be smooth sailing.
