Reborn and become a Great Scientist

Chapter 253 201 Genius Reporter Crowther
Kapiza was overjoyed, while Chen Muwu sighed.

Now he has finally pushed himself to a dead end, allowing him to realize once again what a dead line is the primary productive force after a few years.

Chen Muwu didn't need to worry too much about the theoretical research.

With him and without him, basically there is not much difference.

Ramsey's math papers, he was basically not helpful.

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

If the level of IQ of these individuals cannot even write a lecture on quantum mechanics, then Chen Muwu himself would not believe it.

But Chen Muwu is really hard to say whether the quantum mechanics lecture notes they compiled will be understood by students who use this book in class or learn by themselves in the future.

Although Einstein was the discoverer of the theory of relativity, the textbooks used by German physics students in class are still "Pauli's works".

However, Fowler instructed Dirac to write this handout from the very beginning. He should have foreseen what his student would write a book.

Since he was not afraid, Chen Muwu was even less afraid.

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

Before leaving, Chen Muwu left a piece of advice to the handout writing team.

He asked them to go to Trinity College from time to time to chat with Dean Tomson to learn from him. After all, many textbooks on physics and mathematics used by Cambridge students are written by him.

Among these people, only von Neumann would occasionally come to chat with Chen Muwu and discuss some issues.

The paper on decidability co-written by the two of them has been submitted to the "Proceedings of Natural Science" of the Royal Society of London.

The editors of the editorial department, although they don't know why Chen Muwu has changed his previous method in the past one or two years, no longer acting alone, but publishing articles with others every day.

But as long as there is this Chinese name that obviously does not conform to the English spelling rules in the author column, and the content of the paper is generally related to science, whether it is theory or experiment, they will arrange to publish it as soon as possible.

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

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

What was the result?Isn't it true that Dr. Chen's thesis is correct, and the leaders of the mathematics world are deflated?
The distrust of Dr. Chen's thesis is not against Dr. Chen, but against themselves.

After wasting time and paying a review fee, why bother to end up with a paper that was correct from the start?
Therefore, this mathematical paper co-written by Chen Muwu and von Neumann, after arriving at the editorial department, 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, when Chen Muwu left the UK In the issue of Sulian's "Meeting".

Now that von Neumann came to find Chen Muwu, the issue discussed was of course no longer the matter of determinability.

He was very interested in the Chen Ji that Chen Muwu created to verify this question.

How can this virtual machine, which can only be imagined by the brain, be transformed into real life?
Every time von Neumann raised various related questions, Chen Muwu could only answer a few vague words.

Although he knew the answer, he couldn't say the answer?
Tubes, transistors, chips...

Regardless of how surprised the other party was after hearing these topics, even if it took a few days and nights to tell von Neumann about this matter from beginning to end, he, who is gifted and intelligent, would be able to understand it immediately. .

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

For this thing, it will take another 30 to [-] years. After returning to China, it will not be too late to go to Beijing 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 the country, it is estimated that even if he does as the Romans does and takes a Chinese name, most of the institute will be willing to call his director by his nickname, Lao Feng.

I sent a telegram back to the Crown Prince of Sweden, saying that I agreed to accompany him to visit China, and after roughly arranging the theoretical work, the only thing waiting for Chen Muwu was the proton source at Cockcroft. this matter.

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

With the "cannonball", it can be accelerated through the long "barrel" and finally hit the target.

Isn't this particle accelerator a kind of electromagnetic gun?
It's just that the shells are slightly smaller than the regular ones.

This Van de Graaff generator can produce a large positive 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 fed with negative charges, the negative high voltage can also be produced according to the same principle.

But for now, negatively charged high voltage is useless. Although it can accelerate negatively charged particles, there is only one kind of negatively charged particles commonly found in laboratories, and that is electrons.

Bombarding the target nucleus with electrons accelerated to a high speed, that feeling is more funny than carrying a toy gun loaded with BB bombs to the battlefield.

As for how to prepare a large number of protons. ,

Compared with the proton and the hydrogen atom, there is only one electron difference between the two.

Hydrogen atoms are the only atoms that make up hydrogen gas, which can be easily produced in the laboratory or in industry.

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

It is definitely not feasible to cut directly with a knife. He is not Academician Hou Xiaoming of Beijing University of Science and Technology, and he does not have such superb knife skills to cut the magnetic monopole directly from the magnet.

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

It only needs to inject hydrogen gas into the vacuum environment, and then collide with it with an electron beam with a certain energy to ionize hydrogen molecules into protons.

Then, from the plasma composed of hydrogen molecules, electrons and protons, high voltage is used to attract the protons inside, and after rectification, a good proton source can be obtained.

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

Regarding theoretical issues, Chen Muwu has already explained clearly.

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

The most important piece of equipment inside is the vacuum pump, but that's not a problem for the Cavendish Laboratory.

De Broglie donated one before, and after Chen Muwu finished the electron diffraction experiment, it was in the hands of Professor Aston who developed the mass spectrometer.

He imitated and improved the vacuum pump purchased at a high price, and now the vacuum level and precision of the Cavendish Laboratory are absolutely world-leading.

But all the people in the laboratory are not interested in this. No one is willing to increase investment and research and development in order to pursue a world-leading high vacuum like Dewar and Onnes competed in low-temperature physics. There's no need to do such a thankless thing.

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

As for the degree of vacuum, just enough.

In your room in Cambridgeshire, where the generator is installed, the habit of leaving get off work on time at [-]:[-] in the Cavendish laboratory has long since disappeared.

Chen Muwu, Zhao Zhongyao and Cockcroft worked overtime and spent several days to finally finalize the design of the proton source and draw the sizes and shapes of the required parts that needed to be made additionally. above the blueprint.

Just like the old rules of making motors, it is also necessary to send the blueprints of these parts that require metal processing to the factory that cooperates with the laboratory, and ask them to help make them.

Since it is a 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 this thing must not be successfully developed before he left.

But after he comes back, can he catch up with the nuclear transmutation that participated in the first artificial participation?

If two months later, the inefficient British factory has not produced the parts, then he will have no problem catching up.

But the impatient Rutherford should not tolerate this matter.

Even if the factory gave a reply that it would really take two months to make such a few parts, he would definitely write letters, telegrams and phone calls to the factory, and even go to the factory in person to supervise and urge him.

Chen Muwu felt that he might not be able to keep up with the first experiment, so he could only remind Cockcroft and Zhao Zhongyao repeatedly before leaving.

You must stick to your beliefs, and you must not be soft-hearted for a moment, follow Rutherford's request, and use deuterium as a target for experiments.

Bombarding a deuterium target with high-energy protons will not produce any results, and it is quite troublesome to produce deuterium gas with relatively high purity.

After finishing his heartfelt words, Chen Muwu immediately regretted it.

How can I be so outspoken without hiding my secrets?
We should really let the teacher and the others hit the wall and waste more time on the collision of hydrogen and deuterium.

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

Although the relationship between him and Einstein eased a lot because of overthrowing Hilbert's beautiful vision.

But Chen Muwu felt that it would be better for the relationship between the two of them to be closer.

That's right, while Chen Muwu, Zhao and Kao were burning ointment in the small room to carry on the sundial, Kapica had already obtained a visa for him to go to Sulian.

To be fair, he has been wandering abroad for so long and hasn't returned home for more than three years, so it's inappropriate to go back empty-handed.

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

But Oppenheimer went home at the end of last year, didn't he also buy so many things in big bags?
It's just that Chen Muwu's time is really tight. He has to leave now so that he can join the Swedish crown prince and his party who set off from Sweden after half a month of visiting and giving lectures in Sulian.

Anyway, after this trip, the family members will definitely be taken to England by him, it doesn't matter whether they bring any gifts or not.

Chen Muwu didn't even pack his Cambridge University diploma in his luggage. He only brought a change of clothes on the way, and the four treasures of the study, pen, ink, paper and inkstone. outline.

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

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

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

Not only did his trip happen in a hurry, but the preparation process was also going on in secret.

The people in Cavendish Laboratory were basically kept in the dark.

After receiving the visa, Chen Muwu 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 he was relieved when he heard that Chen Muwu was going back to China to visit his relatives, and he would definitely come back within two or three months.

There is no way to refuse this reason, Rutherford can 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, it was not Rutherford who reacted the most, but Oppenheimer.

When he heard that Chen Muwu was leaving, he immediately went to the Sulian embassy to apply for a visa, so he went with him.

But Chen Muwu was going to leave in two or three days. His visa must not be issued so quickly, which made Oppenheimer anxious to death.

He could only agree with his teacher and let him wait for him in Lezhigrad. After the visa was issued, he would immediately run there to meet him and follow him to go to China in the far east. a turn.

Oppenheimer has already talked about this, and it would be impolite to refuse.

It is also good to let him meet the customs of the East in advance. After all, he still has a lot of affection for the Far East. In the future, he will even send two precious children to the Far East.

Crowther, a gifted journalist of news coverage, once again exploited this issue.

On the front page of the "Manchester Guardian" the next day, a line of big bold letters appeared on the key news preview:
"Dr Chen Muwu is about to leave Cambridge University".

Newspaper readers who didn't know the truth were attracted by this headline one after another.

Everyone thought that a few days ago, the chancellor of Cambridge University, Balfour, planned to expel Chen Muwu because of his support for the strike, and it finally came to an end.

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

Not being welcomed by Cambridge University, let you go, don't you also go quietly?

But most people feel that Dr. Chen is a pity.

Truth failed to defeat power, so he could only leave sadly.

When they followed the marks on the newspaper and turned to the corresponding science and technology section, they found the headline "Dr. Chen is about to leave Cambridge."

But under this title, there is another line of small print subtitles:
"...Leaving Cambridge, I was invited by the Sulian Academy of Sciences to visit Sulian."

Whoops!
White happy/disappointed!
