Anyway, the particle accelerator had reached a bottleneck, so Chen Muwu moved his office back to the Cavendish Laboratory.

Compared to Trinity College, this place is still more convenient.

Whether it is Dirac at St. Peter's College or Ramsay at King's College, they can enter and exit the laboratory freely without having to abide by outdated and rigid rules.

Because Chen Muwu himself is a dabbler, although he wants to help Ramsey, his ability is limited.

However, it has been more than two years since the handshake question was raised, which has allowed Ramsey to continue thinking about this theorem for a long time. Basically, he already has a formed thesis framework in his brain.

Seeing that he couldn't get any more inspiration from Chen Muwu, he had no choice but to follow the established direction.

On the contrary, Dirac and Chen Muwu got along very well, because this is what he did in his old field.

But Chen Muwu’s thesis plan came to nothing.

Because he proposed an incompleteness theorem, which shocked the entire mathematical community, Chen Muwu received congratulatory letters from various people from all directions.

In the past few years since arriving at Cambridge University, every time Chen Muwu published an experimental or theoretical result, someone would always write to him to congratulate him.

If this result is reported by newspapers, there will be a lot of letters, and the identity of the letter writer is not limited to the scientific community.

But if it is not reported and is only published in professional journals of the corresponding discipline, then the number of letters will naturally be smaller, and accordingly, the content discussed in it will be more meaningful.

Among them, one person who frequently wrote to Chen Muwu was Bohr.

On the one hand, this is because their academic views are consistent in most cases. Except for that time a long time ago, Bohr flatly denied that light is a particle, and even sacrificed energy conservation to come up with the BKS theory. Then he was slapped in the face.

On the other hand, it was because as the director of the Institute of Theoretical Physics, Bohr had always wanted to lure his good junior fellow student to Copenhagen from his teacher.

So every time he learned that Chen Muwu had come up with something new, Bohr would always write to his junior brother as soon as possible, and even accompany him personally to Stockholm to receive the Nobel Prize. The main thing was to accompany him first hand.

So the Incompleteness Theorem is no exception. Bohr's usual rainbow fart, and of course at the end there is the sentence "Copenhagen needs theoretical talents like you. As long as you talk about it, your salary and everything will be arranged for you." .

However, after extending the olive branch this time, Bohr added another paragraph to the letter, asking Chen Muwu that he had previously said that he would write another paper on quantum mechanics, what was the specific content, and whether it had been published.

Chen Muwu had wanted to write the thesis, but now he was reminded by Bohr, so he expressed his thoughts to Dirac.

He wanted to prove the strict mathematical equivalence between matrix mechanics and wave mechanics in Hilbert space, and he needed the help of a top student in the mathematics department.

Facing Chen Muwu's invitation, Dirac gave him an answer that was both good and bad.

The good news is that Fowler, who was born in the Department of Mathematics, also believed that this problem was worth studying, so he handed it over to Dirac. After a long period of careful consideration, he already had a very complete idea.

The bad news is that Dirac not only had a very complete idea, but he had even solved the problem.

send.

Chen Muwu had always thought that his idea was very good. It was more than enough to write a paper, and it could also bring a little mathematical shock to physicists.

But who would have thought that he has already finished writing it!

"Paul, have you submitted your paper yet?"

"Thesis? I didn't write a thesis, but I wanted to write this calculation and derivation process into the "Quantum Mechanics" lecture notes that I will write soon."

Dirac's straightforward answer made Chen Muwu dumbfounded.

If you write something that is basically a pure mathematical proof into a physics textbook, then this proof process, or who is this book for?

Of course, it's okay to show it to a few mathematics students who are interested in quantum mechanics, but it's a bit of a trick.

If it were indeed a physics textbook, most physics students would not be able to understand it if this proof process was written in it, right?

"Paul, why don't you write this part of the content in a book, but write it as a paper and publish it. Otherwise, when the time comes, the school who teaches based on your book will learn this chapter, whether it is the teacher giving the lecture, or listening to the class. students, it will be a torture for them.”

Dirac's main focus was to listen to advice. At first, he only regarded this proof as a thinking question assigned to him by his tutor Fowler. Even though he had solved it, there was no need to write it into a paper.

But since Chen Muwu said so, it doesn't matter if he writes it down.

Chen Muwu, who came late and lost the right to authorize a paper, had to find another way to do what he promised Bohr.

Although today's forms of entertainment are scarce compared to those of later generations, Cambridge students are always finding new ways to have fun.

Drinking, dancing, participating in sports, and watching movies are traditional entertainment activities that have always been popular.

Mahjong suddenly became popular at Cambridge University a few years ago, and it is still thriving.

However, recently, these over-energetic college students have developed a new sport, and that is racing.

In recent years, the automobile industry has developed rapidly in both the United States and Europe.

The types and shapes of cars are also changing with each passing day, and more and more cars are beginning to adopt the route of fully enclosed compartments.

The Lagonda convertible that Kapitsa bought two years ago was still fashionable at the time, but now it is on the verge of becoming obsolete.

Moreover, the power system of the car has also been greatly improved, so his car no longer has any advantages in terms of appearance or performance. The car costing 1,200 pounds has rapidly depreciated in value.

But Kapitsa is a man who can't sit still. Of course he is unwilling and will never miss this new racing sport.

If he was not busy, he would be involved in every racing event at Cambridge University, but every time he failed, he never achieved any good results.

If you want to get good results, you have to change your car.

If you want to replace a car, you have to spend money on it.

But Kapitsa ran out of money.

The reason why he has been able to live very happily at Cambridge University in the past three years is that in addition to the dead wages he received from Trinity College and the Cavendish Laboratory, he was able to receive an additional Clark Maxwell Scholarship every year.

This scholarship is also awarded by the Cavendish Laboratory to the best students or newly graduated staff who have just entered the workforce.

Scholarships have been awarded since 1920 and are selected every three years.

The first person to receive a scholarship was Chadwick in 1920, and the second time three years later was Kapitsa's turn.

By last year, he had received the last payment of the three-year scholarship. This scholarship explicitly stipulated that it could not be repeated. This year, its third winner will be selected.

It stands to reason that the best student in the Cavendish Laboratory now is undoubtedly Chen Muwu.

Even if Chen Muwu had arrived at Cambridge University a few months earlier, there might not have been anything wrong with Kapitsa in 1923.

Not long ago, Rutherford also revealed to Chen Muwu that if nothing unexpected happens, this scholarship should be given to him in the next three years.

But looking at the hesitant expression on his teacher's face, Chen Muwu knew what Rutherford was holding in his heart and what he wanted to say but didn't say out loud.

"Teacher, I'm very rich now, so I don't want the Clark Maxwell scholarship money. I'd rather give it to classmates who need it more."

Chen Muwu should be the richest student in the entire Cavendish Laboratory, besides Oppenheimer.

Just a Nobel Prize in Physics with a prize of seven to eight thousand pounds can kill the entire net worth of many students in an instant.

Therefore, the Maxwell Scholarship, which is only 600 pounds per year, is just the icing on the cake for Chen Muwu.

But for other poor students, this six hundred pounds is by no means a small amount, it is completely a help in times of need.

However, when it came to persuading people to give up scholarships, Rutherford, a teacher, certainly couldn't say it directly.

Whether Chen Muwu wants it or not is one thing, but whether he wants it or not is another thing.

He doesn't have to give it, but you can't give it to him.

Fortunately, after hearing Chen Muwu's answer, Rutherford's frown immediately relaxed.

In addition to having a high IQ, this good student of his also has a low emotional intelligence. He can observe words, colors, subtleties, and understand what others are thinking.

Before the announcement of the new Maxwell Scholarship, Chen Muwu didn’t know who the new winner would be.

All he knew was that Kapitsa must not be.

Taking a salary from Trinity College and a salary from the Cavendish Laboratory, even without the scholarship, will have little impact on Kapitsa's quality of life.

However, since last year, he has been in love with Anna, who is far away in Paris, and the travel expenses each time are a huge expense.

Under such circumstances, it is definitely wishful thinking to want to buy a new car worth at least one thousand pounds to participate in racing activities.

Unless you can find other ways to make money, or find other ways.

The clever Kapitsa found the solution, Chen Muwu.

Since Rutherford knew that Chen Muwu was rich, Kapitsa also knew it.

Rutherford was too embarrassed to directly tell Chen Muwu to give up his scholarship, and Kapitsa was also embarrassed to directly ask Chen Muwu to borrow money.

So he drove a convertible Lagonda with a crocodile welded on the radiator just like he did two years ago. After seeing Chen Muwu, he asked him to get in the car without any explanation and said he would take him for a ride around Cambridgeshire. wind.

Although he didn't know what he was up to, Chen Muwu thought it would be good to sit in the car and enjoy the breeze, just to think about the subject matter and ideas of the paper.

Dirac, who was usually taciturn and restless, actually asked to be taken along for the ride this time.

So except for Blackett's absence, three of the four Cavendish trio were in the car.

Kapitsa, who was already used to racing, drove the car very fast. Chen Muwu sat on tenterhooks, regretting that he would cause some kind of accident.

If this car accidentally hits a tree, I wonder if the history of physics will be rewritten in the next few decades.

God bless, the car finally stopped under the shade of a big tree without any danger.

Kapitsa was calm and relaxed, Chen Muwu was sweating profusely, and Dirac was excited.

Kapitsa, who had already made a plan in his mind, began to lobby Chen Muwu to buy a car and drive it.

Not only does he have so much money, but also with the series of honors he has received and his popularity at Cambridge University, it is really unreasonable to not buy a car of his own but to ride a bicycle like Eddington all day long. Some price drops.

After putting on the hat for Chen Muwu, Kapitsa, who had seen him in person, began to sell him the second-hand car that everyone was sitting on.

“Although I bought this car two years ago, it has been very well maintained in the past two years, and its appearance and color are very fashionable, which is very suitable for young people like you.

"Chen, instead of buying a new car, it is better to buy this one. I spent one thousand two hundred pounds two years ago, plus the cost of maintaining and updating parts in the past two years also cost a lot of money.

"As for the condition of the car, you have experienced it personally today. I don't want more. I only want you eight hundred pounds. How about it? Is it a reasonable price?"

Chen Muwu didn't know that Kapitsa wanted to buy a new car, so he didn't understand why Kapitsa suddenly said he wanted to sell the car to him today.

He didn't want to agree to this innocent thing at all, but he didn't expect that Kapitsa had already set the price.

Seeing that, if he couldn't defeat Chen Muwu, Kapitsa would even want to buy and sell by force.

Uh, do you want to buy a car?

You can buy it, but it’s not necessary.

Cambridgeshire is such a big place, and riding a bicycle is enough for daily use. What's the point of buying a car?

Could it be that I wanted to drive to London, but with the traffic and road conditions, driving was completely torturous.

He is not a car enthusiast!

not to mention……

"Peter, if I want to buy a car, why don't I buy a new car with better condition and performance, but why should I buy your car?

"And if the car was as good as you said it was, why did you sell it?"

"Well, this is naturally because I just said that the appearance and color of this car are too fashionable, suitable for young people like you, but I am in my thirties this year, and I feel a little unsteady when driving this kind of car. ”

Kapitsa temporarily found an excuse, but if he could be considered stable, then there should be no ungentleman in Cambridge University.

"I don't want it," Chen Muwu shook his head, "If I wanted to drive, I would buy a new car and drive it myself."

Kapitsa was a little disappointed. If his car couldn't be sold, he would never be able to raise enough money to buy a new car.

But, buying a new car?

Yes, racing, why do you need to use your own car?

Chen Muwu and he are good friends. If he wants to buy a new car, it is equivalent to owning a new car.

It’s not too much for good friends to borrow each other’s cars and drive around, right?

Kapitsa immediately found a better way than selling his car at a discount. He wanted to sell Chen Muwu a car that he had long been optimistic about.

If Chen Muwu can buy this car back, coupled with his excellent driving skills, he will definitely win the first place in the Cambridge racing competition.

Kapitsa was about to continue speaking, but unexpectedly, another person in the back seat spoke earlier than him.

"Peter, if you sell this car, can it be cheaper? I want it very much, but I can't afford eight hundred pounds for a while."

Dirac still couldn't get over the excitement of racing. At this time, his voice when he asked questions was many times louder than when he usually spoke.

Although the second-hand car sales event carefully planned by Kapitsa failed to seduce Chen Muwu, the buyer he thought was the most likely enemy, it did wake up the future No. 1 road killer at Cambridge University in advance.
