Kapitsa was overjoyed, and Chen Muwu sighed.

Now he has finally forced himself to a dead end, so that after a few years, he once again realized what is called the dead line is the primary productive force.

Regarding those things about theoretical research, Chen Muwu didn't have to worry too much.

There is basically not much difference between having him and not having him.

Ramsey's math papers, he basically couldn't help.

As for the lecture notes on quantum mechanics, Dirac, who has already received his Ph.D., is now at full speed, with the help of Oppenheimer and von Neumann, and recently a new Heisenberg.

The IQ level of these individuals, if you can't even write a lecture note on quantum mechanics, then Chen Muwu himself doesn't believe it.

But if you want to talk about the quantum mechanics lecture notes they have written, whether the students who will use this book in class or learn by themselves in the future can understand it, this Chen Muwu is really hard to say.

Although Albert Einstein was the discoverer of the theory of relativity, the textbooks used by German physics students are still written "Pauli".

But this handout, which Fowler instructed Dirac to write at the very beginning, should have foreseen what his master would write a book.

Since he is not afraid, Chen Muwu is even more afraid.

Anyway, the name on the author's column of this book is very luxurious, and he is not a shame.

Before leaving, Chen Muwu left a clever plan for this handout writing team.

He asked them to go to Trinity College from time to time to chat with the dean of Thomson, after all, many of the physics and mathematics textbooks used by Cambridge students today were written by his old man.

Of these people, only von Neumann occasionally came to chat with Chen Muwu and talk about some issues.

The paper on the conclusive nature that the two of them had written together had been submitted to the Proceedings of the Royal Society of London.

The editors of the editorial department, although they don't know why, in the past year or two, Chen Muwu has changed his previous way and no longer works alone, but publishes articles with others every day.

But as long as the author column has this Chinese name that obviously does not conform to the English spelling rules, and the content of the paper is broadly related to science, whether it is a theory or an experiment, they will arrange for publication as soon as possible.

Previously, the editorial board's trust in Chen Muwu was limited to physics and astronomy.

The editorial department could not make up their minds about the incomplete principle of the paper, so they could only send letters to several well-known mathematicians in the UK, asking them to help review the paper.

What was the result? Isn't Dr. Chen's paper correct, but the leaders of the mathematical community are stunned?

The distrust of Dr. Chen's dissertation is not that they can't get along with Dr. Chen, but that they can't get along with themselves.

It's a waste of time, and a review fee, so why bother ending up with a paper that's accurate from the start?

So the mathematical paper co-written by Chen Muwu and von Neumann, after arriving in the editorial office, did not enjoy the treatment of the previous mathematical paper, but directly proofread and typeset, and planned to publish it in the latest issue, that is, the issue of the "Huibao" where Chen Muwu left the UK for Sulian.

Von Neumann now came to Chen Muwu, and the issue to be discussed was of course no longer decisive.

He was very interested in Chen Muwu's Chen machine in order to verify this problem.

How can we turn this virtual machine, which can only rely on the imagination of the brain, into real life?

Every time von Neumann asked a variety of related questions, Chen Muwu could only respond vaguely to a few words.

Although he knows the answer, he can't say the answer.

Tubes, transistors, chips......

Regardless of the degree of surprise the other party was upon hearing these topics, even if it took a few days and nights to tell von Neumann about this matter from beginning to end, he would be able to understand it at a glance even if he was gifted and intelligent.

But Chen Muwu felt that even if they were given ten or even twenty years, they would not be able to achieve any results.

This thing will be another twenty or thirty years, and after returning to China, it will not be too late to go to Shaojing to ask for a place called Zhongguan Village, build some buildings and research institutes, and then conduct research.

At that time, if von Neumann is willing to follow him back to China, it is estimated that even if he follows the local customs and takes a Chinese name, most of the people in the institute will be willing to call him by his nickname, Lao Feng.

sent a telegram back to the crown prince of Sweden, saying that he had agreed to accompany him on a visit to China, and after roughly arranging the theoretical work, the only thing waiting for Chen Muwu was the proton source on Cockcroft's side.

If the motor is a cannon, then the particle source that generates protons is equivalent to a cannonball loaded into it.

With the "shell", it was possible to accelerate through the long "barrel" and finally bombard the target.

Isn't this particle accelerator a kind of electromagnetic gun?

It's just that the shells are a little smaller than the regular ones.

This Van der Graaf motor can produce a large positive electric high voltage.

If the DC power supply that supplies power to the conveyor belt at the lowest end is reversed, and the conveyor belt is sent with a negative charge, the negative electric high voltage can be created according to the same principle.

But for now, negative electric high voltage is useless, although it can accelerate negatively charged particles, but there is only one kind of negatively charged particle that is common in the laboratory, and that is electrons.

Bombarding the nucleus of a target with electrons that are accelerated to high speed is funnier than carrying a toy gun loaded with BB bullets on the battlefield.

As for how you can prepare a large number of protons. 、

Compared to the proton and hydrogen atoms, there is only one electron difference between the two.

Hydrogen atoms are the only atoms that make up hydrogen, and hydrogen can be easily prepared in laboratories or industries.

Therefore, if you want to make a proton source, the most troublesome step is how to separate the nucleus of hydrogen atoms from hydrogen.

It is definitely not feasible to cut directly with a knife, and he is not an academician of Beijing University of Science and Technology, and he does not have such superb knife work, so he can cut the magnetic monopole directly from the magnet.

But there is no need to rely on knife work to strip electrons from hydrogen atoms.

Hydrogen is only injected into a vacuum, and then an electron beam with a certain amount of energy collides with it to ionize hydrogen molecules into protons.

Then from this plasma composed of hydrogen molecules, electrons and protons, the protons in it are attracted by high voltage, and after rectification, a good proton source can be obtained.

The principle is simple, but the process is more complicated.

Chen Muwu has made it clear and clear about the theoretical issues.

But how to turn this theory into a blueprint, and how to produce a physical object according to the blueprint, depends on Cockcroft, a hands-on expert with an engineering background.

The most important piece of equipment was a vacuum pump, but it wasn't a problem for the Cavendish lab.

De Broglie donated one before, and after Chen Muwu completed the electron diffraction experiment, it went to the Aston professor who developed the mass spectrometer.

He copied and improved the vacuum pump he had purchased at a high price, and now the Cavendish laboratory is a world leader in vacuum level and accuracy.

But no one in the lab was willing to invest in and develop the world's first high vacuum as Dewar and Onnes did in their race to low temperature physics – and there was no need for such a thankless task.

The attitude is also very pragmatic, and the focus of the work must be on particle physics.

As for the vacuum, it's enough.

Your room with a motor in Cambridgeshire has long since lost the habit of leaving work at six o'clock every day in Cavendish Laboratory.

Chen Muwu, Zhao Zhongyao, and Cockcroft worked overtime and spent several days to finally finalize the design of the proton source, and draw the dimensions and shapes of the parts needed and the additional parts needed to be made onto the blueprint.

As with the old rules for making electric motors, it is also necessary to send the blueprints of these parts that need to be processed to the factory that cooperates with the laboratory and ask them to help make them.

Due to the special shape that needs to be customized, it is still unknown how long it will take to complete the production and send it to Cambridge University.

Chen Muwu felt that before he left, this thing would definitely not be successfully developed.

But when he returns, will he be able to participate in the first human nuclear transmutation?

If, two months later, the inefficient British factory had not yet made the parts, he would have no problem catching up.

But Rutherford, who was anxious, should not tolerate this.

Even if the factory replied that it really took two months to make such a few parts, he would definitely write letters, telegrams and phone calls to the factory twice in three days, and even personally go to the factory to supervise and urge.

Chen Muwu felt that he probably couldn't catch up with this first experiment, so he could only tell Cowcroft and Zhao Zhongyao again and again before leaving.

We must insist on our own beliefs, and we must not be soft-hearted and follow Rutherford's requirements and use deuterium nuclei as targets for experiments.

Bombarding a deuterium target with high-energy protons not only yields no results, but it is also quite troublesome to produce deuterium gas with higher purity.

After saying these heartfelt words, Chen Muwu immediately regretted it.

Why is he so straightforward and unselfish?

The teacher should have crashed into the south wall and wasted more time on the hydrogen-deuterium collision.

In this way, if I come back from China, I may be able to catch up with this experiment to verify the mass-energy equation.

Although because of the overthrow of Hilbert's beautiful ideas, the relationship between him and Einstein eased a lot.

But Chen Muwu felt that the relationship between the two of them was better to get closer.

That's right, just when Chen Muwu, Zhao and Kao were burning anointing oil in the small room to follow the sundial, Kapitsa had already given him a visa to go to Sulian.

To be reasonable, he has been adrift abroad for so long, and he has not returned home for more than three years, so it is not appropriate to go back empty-handed.

The transportation between the United Kingdom and the United States is so convenient, and the import and export of goods is not low.

But when Oppenheimer returned home at the end of last year, didn't he also buy so many things in a big bag?

It's just that Chen Muwu's time is really urgent, and he must set off now, so that he can meet the Swedish crown prince and his party from Sweden half a month after Su Lian's visit and lecture.

Anyway, after this trip, his family will definitely be brought to England by him, and it doesn't matter if he brings any gifts or not.

Chen Muwu didn't even pack his Cambridge diploma in his luggage, he only brought a change of clothes on the road, as well as the four treasures of pen, ink, paper, inkstone, and study, and planned to draw up a rough outline for this lecture on the train to Lenin.

That's right, although the name is called the Sulian Academy of Sciences, but this unit named after the country is not currently in Moscow, the capital of Sulian, but in St. Petersburg, the capital before Tsarist Russia.

In the planned itinerary given to him by Kapitsa, his visit was basically in this city, and only when he took the Trans-Siberian line by train, he would pass through and stop in Moscow for a short time.

The meeting place agreed by Chen Muwu and the Crown Prince of Sweden is also here.

Not only was his trip rushed, but the process of preparation was also carried out in secret.

The people in Cavendis's lab were basically kept in the dark.

Chen Muwu, who got the visa, went to the director's office to ask for leave.

Hearing that Chen Muwu was leaving Cambridge, the hairs on Rutherford's body stood on end.

But when he heard that Chen Muwu was going to return to China to visit his relatives and would definitely come back in two or three months, his heart relaxed.

There was no way to refuse this reason, and Rutherford could only tell the good students to go and return quickly, and pay attention to safety on the way back and forth.

However, in the Cavendish laboratory, the biggest reaction was not Rutherford, but Oppenheimer.

When he heard that Chen Muwu was leaving, he immediately went to Sulian's embassy to apply for a visa and followed him.

But Chen Muwu will leave in two or three days, and his visa will definitely not come down so quickly, which makes Oppenheimer anxious to death.

He could only tell his teacher to wait for him in Leggrad, and when the visa was issued, he would immediately run there to meet him, and follow him to China in the Far East.

Oppenheimer has already said this, and it would be rude to refuse again.

It's not bad to let him see the customs of the East in advance, after all, he still has a lot of feelings for the Far East, and he will even send his two precious children to the Far East in the future.

Crowther is a brilliant journalist who has once again taken advantage of the issue.

On the front page of the Manchester Guardian the next day, a line in bold letters appeared on the key news preview:

"Dr. Muwu Chen is leaving the University of Cambridge".

Newspaper readers who did not know the truth were attracted by this headline.

Everyone still thought that a few days ago, because of support for the strike, Balfort, the Chancellor of Cambridge University, planned to expel Chen Muwu, and finally ushered in the finale.

Some people want to see Chen Muwu's jokes, a Chinese, even if he has achieved so many academic achievements, what about it?

Not treated well by Cambridge University, let you go, don't you also roll quietly?

But most people think Dr. Chan is a pity.

Truth failed to triumph over power, and he had no choice but to leave in disgrace.

After they flipped to the corresponding science and technology page according to the marks in the newspaper, they found the headline "Dr. Chan is about to leave Cambridge".

But underneath this heading, there is another line of subheadings in small print:

“…… Leaving Cambridge, he was invited by the Sulian Academy of Sciences to visit Sulen. ”

Alas!

White is happy/disappointed!
