Two days later, the Cavendish lab held a doctoral dissertation defense.

April is not the usual graduation time for Cambridge University, and this defense meeting was also held for Zhao Zhongyao and Cockcroft, who failed to defend last summer.

In the eyes of Liang Sicheng and Lin Huiyin, who came to Cambridge University to visit and visit, since Zhao Zhongyao and Cockcroft have both won the Nobel Prize in Physics, the defense meeting to win the title of doctor should be just a defense meeting that goes through the motions.

It can't be said that they have all won the Nobel Prize in physics, but they can't even pass their doctoral dissertations, right?

It's as ridiculous as someone who can win a gold medal in the 100 meters at the Olympics and set a world record, but run the penultimate place in the 100 meters at a school sports day.

However, not everything in the world is like someone's imagination, but it can always break through the cognition of others again and again.

The meeting in the Cavendish conference room was still very harsh, and both the people on the stage and the people who raised the price to ask questions said a lot of physics knowledge that the two of them did not understand at all.

The one with a mustache and a tall build. was introduced by Chen Muwu as his teacher in the Cavendish laboratory, and Rutherford, who was also the director of the laboratory, had a serious face.

Seeing him like this, Lin Huiyin even felt that the result of defending these two Nobel Prize winners in physics on the stage would be more than auspicious today.

After everyone asked questions about the content of the paper in turn, Rutherford finally opened his mouth and asked Zhao Zhongyao and Cockcroft the same question respectively: "What do you think the particle accelerator should look like if it continues to develop backwards, and what will it become?" ”

A layman like Lin Huiyin can hear that the last question does not involve a lot of professional physics knowledge, but is just a kind of imagination for the future based on existing theories.

But the two people who answered the question on the stage both coincidentally got stuck on this last question.

They were all at odds with each other, unable to speak, and even embarrassed to the point that they couldn't get on or off the stage for a while.

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

"Consider Professor Einstein's relativistic effect."

Chen Muwu's words were like a code, and not long after he said it, 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, because considering the relativistic effect, blindly increasing the acceleration voltage will not make the accelerated particles gain a linear increase between the speed and voltage. So it is necessary to think about how to break through this bottleneck, and in a short period of time, particle accelerators can only accelerate particles to the order of million electron volts. ”

Although Lin Huiyin couldn't hear any useful information from the answers of the two of them, it seemed that he was just saying a sentence back and forth from beginning to end.

But she saw Rutherford, who was sitting in the witness position on the main screen, nodded, indicating that he was satisfied with this answer, and also said that Zhao Zhongyao and Cockcroft passed the doctoral dissertation defense meeting and officially became a member of the doctoral title holders of Cambridge University from now on.

Lin Huiyin couldn't understand this matter, how did she know that the question raised by Rutherford was that he wanted to fight with his favorite student Chen Muwu, and accidentally touched the two pond fish standing on the stage to answer.

Rutherford had long been aware that Chen Muwu took Zhao Zhongyao and Cockcroft, two people who won the Nobel Prize in Physics for particle accelerators, to Sweden so much earlier, and it should be more than just to prepare for receiving the prize.

It was likely that the three of them were working on some new questions about particle accelerators, but when they returned, no matter how much Rutherford tried to side-knock them, he couldn't get anything useful out of their mouths.

Rutherford wanted to know what new idea Chen Muwu had come up with, and today he finally met his good student who had been in his London home for three or four months, so he asked this question to knock on the mountain and get an explanation that Chen Muwu brought him.

Hearing Chen Muwu mention the relativistic effect, Rutherford felt that he should be telling the truth.

It seems that they are in Stockholm, and they should just want to develop a particle accelerator that surpasses the million-electron volts of the Cavendish laboratory, and judging by the expressions on their faces and the answers they just answered, it seems that this research work is not very optimistic?

It's no wonder that Rutherford would make this kind of judgment based on other people's performance, 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 accelerator mode.

This temporary increase in the doctoral dissertation defense meeting was finally held smoothly without danger.

Zhao Zhongyao and Cockcroft, who wore the doctor's hat more than half a year late, became the two most eye-catching people in the audience in the celebration of everyone.

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

Seeing others graduating with doctorates, wearing doctorate robes and doctorate hats, Lin Huiyin felt a little uncomfortable in his heart.

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

The reason given by the university for this is that because Lin Hui is a woman, women cannot officially enter the School of Architecture, and can only audit as an auditor.

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

I heard that many Chinese people at Cambridge University have come to Cambridge in recent years, all because of the face of Dr. Chen Muwu who stood beside them.

Lin Huiyin was even thinking that if he hadn't gone to the United States, but came to the United Kingdom, would he have been able to successfully obtain his degree in the face of Chen Muwu?

While everyone was celebrating the birth of two new doctors in Cavendy's lab, Chen Muwu, who was still sitting on the review bench just now, planned to slip away from this slightly chaotic conference room.

However, some people didn't want to see him do this, Chen Muwu just walked a few steps to the door, and a loud voice stopped his name: "Chen, do you have time to wait?" Shall we go to the office and have a chat? ”

Without looking back, just listening to the loud voice of the person who spoke, Chen Muwu knew that there was no one else except Rutherford.

Regarding the teacher's "invitation", Chen Muwu must not turn a blind eye to hear it, nor can he raise his legs and run away quickly.

He could only stand still, turned around, and nodded at Rutherford with a smile on his face: "Of course, of course. ”

This secret conversation between master and apprentice did not talk too much about physics.

At first, Mr. Chen thought that Mr. Rutherford would ask him what the future of particle accelerators was, as he had just done when he asked Mr. Zhao and Mr. Cockcroft.

But Rutherford was just in his office, constantly persuading Chen Muwu to think about it more, not to make a rash decision, and to leave Cambridge University completely and go to Stockholm, Northern Europe.

For Chen Muwu, this question is much easier than the question he imagined.

If Rutherford asked him what kind of research he was doing in Stockholm, Chen Muwu would really not be able to answer.

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

He said that his home is in London, because the winters in the north are warm and cold, and it is unlikely that a large family will move to Sweden in the future.

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

Chen Muwu's plan for himself is to stay in Sweden for eight or nine months every year, and the remaining two or three months in the UK, so that the two of them have enough time to meet.

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

He has also learned about it through various channels recently, and it seems that Chen Muwu has put a lot of energy into the school in Stockholm.

You can't just use a few words to make him give up the upfront investment that cost a lot of money and be in the Cavendish laboratory with peace of mind, right?

Students always have to fly away after they finish their studies, and Rutherford can still accept this.

At least in the future, I can work with Chen Muwu for two or three months every year, which is already a very good ending compared with Bohr, who also stays in Northern Europe all the year round and may not see each other once a year.

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

The work he has done as a host has been very good, and if the dinner party at Trinity College had been more delicious, it would have earned him more face.

Seeing that the two guests kept as little embarrassed as possible on their faces, Chen Muwu knew that the two of them also could not adapt to this meal, which was the most unpalatable college in Cambridge University despite its long history.

So he spat out 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, and I will definitely make a lot of money in a few years." ”

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

"Dr. Chen, then I estimate that it will be a few decades before the students of Cambridge University will have a good mouth. Because it's impossible to say goodbye to physics research at a young age, right? I think that by that time, the textbooks for physics students will be much thicker than the textbooks we have now. ”

After a few days of getting along, Liang Sicheng also realized that Chen Muwu is not a serious person, but a person who likes to joke.

So he followed in his wife's footsteps and continued to add: "Brother Hanchen mentioned before that there is something called the 'grandmother paradox', a person takes the opportunity of time travel to travel back in time and kill his grandmother decades ago, then whether this person himself will still exist.

"I haven't been too clear about this question, but according to Dr. Chen's statement, this person has traveled to another parallel world, so after killing his grandmother, he will still exist.

"But what I want to say is, will a certain physics student in the future be unbearable to bear the fact that the books are full of physics laws and formulas named after Brother Hanchen, and really invent a machine that can travel time, and force Brother Hanchen to stop studying physics now?"

Without waiting for Chen Muwu to respond, Lin Huiyin took over the conversation again: "You are also a 'grandmother paradox', if you go back to the present and don't let Dr. Chen study physics, then the physics theories and formulas he proposed will not appear, and without these theories and formulas, maybe people will not be able to develop time-travel technology in the future, and naturally they will not be able to go back to the present to stop Dr. Chen." ”

As soon as her words fell, the three of them burst out laughing.

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

The couple had to travel to other countries in Europe for their honeymoon, and they had to rush back home to meet relatives they hadn't seen for a few years, so they parted in London a few days later.

Lin Huiyin expressed his regret that he could not attend Chen Muwu's wedding, while Liang Sicheng only nodded in agreement.

Shortly after they left, however, the housekeeper was tidying up the room and found an envelope under a pillow.

The font in the letter is very familiar to Chen Muwu.

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

In the letter, Liang Sicheng expressed his gratitude to Chen Muwu for his warm hospitality to the couple, and also left 20 pounds in the letter as a gift money from the couple to Chen Muwu, who was about to get married.

For Chen Muwu, twenty pounds was not a lot of money, and he only had to make two bets with Pauli to earn it back.

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

Liang Sicheng and Lin Huiyin have already gone away, and Chen Muwu can't chase them to the train station, to the English Channel, or even to France to return the money.

He could only write down such an account in his heart, and when the time came in the future, he would repay their family more.
