Reborn and become a Great Scientist

Chapter 400 139 Twenty pounds gift

Two days later, the Cavendish Laboratory ushered in a doctoral thesis defense meeting.

April is not a common graduation time at Cambridge University. This defense meeting was also specially held for Zhao Zhongyao and Cockcroft who were unable to catch up with their defense last summer.

In the eyes of Liang Sicheng and Lin Huiyin, who came to the University of Cambridge as guests, since Zhao Zhongyao and Cockcroft have both won the Nobel Prize in Physics, the defense meeting for getting their doctorate titles should be just a formality. That’s all.

It can’t be said that they have won the Nobel Prize in Physics, but they can’t even pass their doctoral thesis, right?

This is as ridiculous as someone who can win the gold medal in the 100 meters at the Olympics and set a world record, but then finishes second to last in the 100 meters at the school sports meeting.

But not everything in the world is like someone's imagination, but it can always break through other people's perceptions time and time again.

The defense meeting that took place in the Cavendish Conference Room was still extremely demanding. Both the speaker on the stage and the person asking questions talked about a lot of physics knowledge that the two of them could not understand at all.

The one had a mustache and was tall. Rutherford, who was introduced by Chen Muwu as his teacher at the Cavendish Laboratory and also the director of the laboratory, looked even more serious.

Seeing him like this, Lin Huiyin even felt that today's result for these two Nobel Prize winners in physics would be disastrous.

After everyone asked questions about the content of the paper, Rutherford finally spoke and asked Zhao Zhongyao and Cockcroft the same question: "Do you think that if the particle accelerator continues to develop backward, What should its form be and what will it develop into?”

A layman like Lin Huiyin can tell that this last question does not actually involve a lot of professional physics knowledge, but is just a fantasy about the future based on existing theories.

But the two people who answered the questions on the stage got stuck on the last question.

They were hesitant and speechless, and at one point they were so embarrassed that they couldn't even get off the stage.

Chen Muwu, who had been silent like Rutherford from the beginning, finally started to save the situation for his two right-hand men after the situation became extremely embarrassing.

"Consider Professor Einstein's relativistic effect."

Chen Muwu's words were like a secret code. Not long after he said them, the two people on the stage gave the answer to Rutherford's question.

"The future development of particle accelerators will enter a bottleneck period that is difficult to break through. This is because taking into account the relativistic effect, blindly increasing the accelerating voltage cannot lead to a linear increase in the relationship between the speed and voltage of the accelerated particles. Therefore, we must consider how to break through this bottleneck. In a short period of time, particle accelerators can only accelerate particles to the order of millions of electron volts."

Although Lin Huiyin could not hear any useful information from the answers of the two of them, it seemed that he was just saying a sentence from beginning to end.

But she saw Rutherford, who was sitting in the witness position on the main screen, nodded, indicating that he was quite satisfied with the answer. At the same time, she also said that Zhao Zhongyao and Cockcroft had passed this doctoral thesis defense meeting, and from now on Later, he officially became one of the holders of PhD title at Cambridge University.

Lin Huiyin couldn't understand this matter. How did she know that Rutherford asked this question because he wanted to have a battle with his favorite student Chen Muwu. He accidentally affected the two questions he was answering on the stage. Pond fish.

Rutherford had long realized that Chen Muwu took Zhao Zhongyao and Cockcroft, two people who won the Nobel Prize in Physics for their particle accelerators, to Sweden so far in advance, not just to prepare for the award.

The three of them were probably studying some new issues related to particle accelerators, but after they came back, no matter how Rutherford tried to insinuate themselves, he could not get anything useful out of these two people.

Rutherford really wanted to know what new ideas Chen Muwu had come up with. Today he finally met his good student who had been staying at his home in London for three or four months, so he raised this question to try to persuade him. He got an explanation brought to him by Chen Muwu.

Hearing Chen Muwu mention the relativistic effect, Rutherford felt that what he said should be true.

It seems that they in Stockholm just want to develop a particle accelerator that surpasses the million electron volts of the Cavendish Laboratory. And judging from the expressions on their faces and the answers just now, it seems that this research work Not too optimistic?

It's no wonder that Rutherford would make this kind of judgment based on the performance of others. Even if he was given another head, without understanding the principle of Chen Muwu's cyclotron, he would never have imagined that his good student was actually trying a new one. Accelerator mode.

This temporarily added doctoral thesis defense meeting was finally held successfully without any danger.

Zhao Zhongyao and Cockcroft put on their doctorate hats, which were overdue for more than half a year, and became the two most eye-catching people in the audience amidst the congratulations.

Liang Sicheng and Lin Huiyin quickly sent their blessings to their compatriot Zhao Zhongyao.

Lin Huiyin felt a little uncomfortable in his heart when he saw other people graduate with Ph.D.s, put on doctoral robes and hats.

This is because he and his husband Liang Sicheng both studied architecture at the University of Pennsylvania. Liang Sicheng has received a master's degree from the University of Pennsylvania, but he has not even received a doctorate.

The reason given by the school is that just because Lin Huiyin is a woman, women cannot officially enter the School of Architecture and can only audit as an auditor.

At this moment, seeing that their compatriots had already obtained doctorates from Cambridge University, Lin Huiyin could only temporarily use his happiness for others to bury the bitterness in his heart.

I heard that many Chinese people have come to Cambridge University in recent years, all because of the reputation of Dr. Chen Muwu who is standing next to them.

Lin Huiyin even wondered, if he had come to the UK instead of the United States, would he have been able to successfully obtain his degree for Chen Muwu's sake?

While everyone was celebrating the birth of two new doctors in the Cavendi Laboratory, Chen Muwu, who had just been sitting on the review bench, planned to slip out of the slightly chaotic conference room.

However, some people didn't want to see him do this. Chen Muwu had just taken a few steps towards the door when a loud voice called his name: "Chen, do you have time to wait? Let's go to the office and have a chat. ?”

Without looking back, Chen Muwu knew that there was no one else but Rutherford just by hearing the loud voice of the person who spoke.

Chen Muwu certainly couldn't turn a blind eye to the teacher's "invitation", nor could he run away quickly.

He could only stand there, turned around, and nodded towards Rutherford with a smile: "Of course, of course." This secret conversation between master and disciple did not talk too much about physics. .

Chen Muwu initially thought that Rutherford would ask him about the future development trend of particle accelerators, just like he had just asked Zhao Zhongyao and Cockcroft.

But Rutherford was just in the office, constantly persuading Chen Muwu, urging him to think more carefully and not to make a rash decision to leave Cambridge University completely and go to the cold Stockholm in Northern Europe.

For Chen Muwu, this problem was much easier than what he imagined.

If Rutherford asked him what research he was doing in Stockholm, it would be difficult for Chen Muwu to answer.

But since he was talking about this topic, Chen Muwu had enough words to make excuses with the teacher.

He said that his home is in London, because the winter in the North is very cold, and there is no possibility that the entire family will move to Sweden in the future.

In this way, he will definitely travel back and forth between the UK and Sweden in the future. He will come to Sweden when the weather is still good, and in winter, he will return to the relatively warm UK to escape the severe cold.

Chen Muwu's plan for himself is to stay in Sweden for eight or nine months every year, and spend the remaining two or three months in the UK. The master and apprentice have sufficient time to meet each other.

Regarding Chen Muwu's answer, Rutherford could only say that he was quite satisfied.

He has also learned about it through various channels recently. It seems that Chen Muwu has invested a lot of energy in the school in Stockholm.

You can't just use a few words to ask him to give up the huge upfront investment and just stay in the Cavendish Laboratory with peace of mind, right?

After completing their studies, students always have to travel far away, and Rutherford can still accept this.

At least I can work with Chen Muwu for two or three months every year in the future. Compared with Bohr, who also stayed in Northern Europe all year round and might not meet once a year, it was already a very good ending.

After leaving Rutherford's office, Chen Muwu also invited Liang Sicheng and Lin Huiyin to attend Trinity College's daily dinner as guests.

He has already done a very good job as a host. If the dinner at Trinity College were more delicious, it would earn him more face.

Seeing the two guests trying not to show any embarrassment on their faces, Chen Muwu knew that the two of them could not adapt to the food of this college, which had a long history but was the most unpalatable in the University of Cambridge.

So he complained mercilessly: "If I don't understand physics research in the future, after I retire, I will find a store next to Trinity College and open a Chinese restaurant. I will definitely make a fortune in a few years." earned a lot."

Everyone knew that what Chen Muwu said was false, but his words still made the two of them smile knowingly.

"Dr. Chen, I guess it will have to wait a few more decades before the students of Cambridge University will be happy. Because you can't say goodbye to physics research at a young age, right? I think of the physics students at that time. The textbooks will definitely be much thicker than the textbooks we have now."

After getting along with each other for a few days, Liang Sicheng also realized that Chen Muwu was not a serious person, but a person who loved to joke.

So he followed his wife's footsteps and continued to add: "Brother Hanchen once mentioned before that there is something called the 'Grandma Paradox', where a person takes advantage of the opportunity of time and space travel to travel back to several times. Ten years ago, if I killed my grandmother, would this person still exist?

"I have never thought about this issue very clearly, but according to what Dr. Chen once said, this person time traveled to another parallel world, so after killing his grandmother, he himself will still exist.

"But what I want to say is, will a certain physics student in the future, unable to bear the physical laws and formulas named after Brother Hanchen in his books, actually invent a method that can carry out time travel?" The machine has come to force Brother Hanchen to stop studying physics?"

Before Chen Muwu could respond, Lin Huiyin took over the conversation again: "You are also a 'grandmother's paradox'. If Dr. Chen is not allowed to study physics back to the present, then the physics theories and formulas he proposed will not appeared, and without these theories and formulas, people in the future may not be able to develop time travel technology, and naturally they will not be able to return to the present to stop Dr. Chen."

As soon as she finished speaking, the three people laughed.

After attending the doctoral thesis defense meeting of Zhao Zhongyao and Cockcroft, and taking the newlyweds Liang Sicheng and Lin Huiyin to visit Cambridge University, the three of them left Cambridge again and returned to London.

The couple also wanted to travel to other European countries for their honeymoon, and they also had to rush back to China to meet relatives they hadn't seen for several years, so they parted ways in London a few days later.

Lin Huiyin expressed his regret for not being able to attend Chen Muwu's wedding, while Liang Sicheng just nodded in agreement.

But not long after they left, the servant at home was tidying up the room and found an envelope under a pillow.

Chen Muwu was very familiar with the font in the letter.

Not long ago, he received a letter from Ottawa, the capital of Canada, and learned that two of his guests were coming to London to visit.

In the letter, Liang Sicheng expressed his gratitude to Chen Muwu for his enthusiastic hospitality to the couple. He also left twenty pounds in the letter as a gift from the couple to Chen Muwu who was about to get married.

For Chen Muwu, twenty pounds was not a big sum. He only needed to make two bets with Pauli to make it back.

But for those two poor students who were away from home, twenty pounds was no longer a small amount.

Liang Sicheng and Lin Huiyin had already gone far, and Chen Muwu could not chase them to the train station, to the English Channel seaside, or even to France to return the money to them.

He could only remember that there was still such an account in his mind, and when the time came, he would repay their family more.
