Princeton, Xu Chuan didn't know what kind of 'surprise' Peverman had brought him, and he was instructing a few students in his office at this time.

Suddenly, the office door was pushed open, and a bushy bearded Feverman walked in.

Xu Chuan pointed to the student and got up and walked towards the friend.

"Xu, I have a job offer here, I don't know if you're interested." Fefferman asked straight to the point.

"What job?" Xu Chuan asked curiously.

"Perhaps you would be interested in an invitation from PPPL Labs to model plasma turbulence?"

Xu Chuan: ????

When this year-old friend said the specific content, his first reaction was: ', there are people who want to harm me!' ’

The second reaction was: "When will Feverman be able to read minds?" ”

Modeling plasma turbulence was indeed one of his ultimate goals in Princeton.

But is this something he can touch now?

Not to mention touching it, when it comes to this kind of knowledge in the field of nuclear physics applications, it is estimated that he will be bad when he comes into contact with it.

In his previous life, he was exposed to the application of nuclear fission physics, which caused him to be stranded here for more than ten years.

It would be stupid to plant it once in this life.

In the office, Feverman looked at Xu Chuan, whose face was uncertain, and asked curiously, "What's wrong with you?" ”

Hearing the inquiry, Xu Chuan came back to his senses and asked in surprise: "How did you study this thing, I remember that you seem to be a distinguished professor of the Fermi National Accelerator Laboratory, right?" How do you get in touch with PPPL Labs? ”

Feverman: "They came from there, and they had some trouble controlling the plasma turbulence and needed a mathematician to help them solve some problems. ”

"But to be honest, I'm not sure about that problem alone, and if you can help, maybe it can be solved. You are more sensitive to mathematics than any professor at Princeton. ”

Xu Chuan shook his head decisively and said, "Nuclear physics is not within my scope of research, and I have my own research in the future, so I'm afraid I won't be able to help with this invitation." ”

He decisively rejected Fefferman's invitation, and was insensitive to the application of nuclear physics.

If he didn't know enough about this friend, I'm afraid he would think that this friend was the one who was arranged by the United States to ask him to stay in the United States.

And in his opinion, Feverman is a little natural, a pure Chinese scholar, if he wants to participate in the nuclear energy research of the United States, it is almost impossible.

He had scarcely ever heard of other scholars of pure Chinese nationality involved in such experiments.

If the PPPL Ion Physics Laboratory invites him to participate in the experiment, he will inevitably mention things like nationality, and it is impossible for PPPL, which is under the management of the Science Office of the University of Energy BU, to put a Chinese person into their laboratory. In particular, it involves such a critical project as controlled nuclear fusion.

......

Seeing off Peverman, Xu Chuan sighed helplessly.

It seems that it is time to plan the journey back to China in advance.

was suddenly cheated by a friend, and despite Feverman's kindness, he still felt quite helpless.

Originally, he also planned to take advantage of the remaining more than a month before the International Congress of Mathematics to quietly talk to some other physics professors, such as Lazersson, Franck, Carr and others.

But now that plan is mostly in vain.

Let's get ready to go back first.

Shaking his head, Xu Chuan said two words to the four students who were studying in the office, and turned around and returned to his villa.

Since he was going to return to China ahead of schedule, some of the precious manuscripts accumulated in the villa in the past two years, such as the letters left to him by Professor Mirzahani, such as the manuscript of his own process of proving the N's equation, and so on.

These precious manuscripts and documents are of great commemorative significance and value to him, and they must be taken with him.

After thinking about it, Xu Chuan picked out the manuscript that proved Hodge's conjecture.

This manuscript was a gift he left to Princeton and the Flintstone Library.

Although he didn't like the country at his feet, he still had feelings for the Princeton school.

Like NTU, Princeton's training of him is real, and he has learned a lot from it in his previous life and in this life.

And leaving a copy of such a manuscript is also a tradition of scholars who have gone out from Princeton.

The reason why the flint library is called the 'treasure library' of libraries is that it contains many original manuscripts of famous scholars, thinking about handwriting and other things.

These things are often lost on the outside and cannot be found at all.

Only here can you see through the stubborn old man.

......

After briefly sorting out the manuscripts in the villa, Xu Chuan also had a headache when he looked at the large number of manuscripts and materials with at least two suitcases.

How do I get these things back home? Do you want to go by courier?

I'm afraid it's not realistic, although I don't know if Mi has monitored itself, but there must be people who keep an eye on it.

The things he mailed back might be noticed, and then these manuscripts would become a signal that he wanted to return to China.

Although the risk is not very large, the lessons of the previous life are too painful, and he wants to minimize the impact of this aspect.

If you don't send it by mail, let someone take it back, or do you want someone here to send it back when you return home?

Just as he was thinking about it, the doorbell of the villa suddenly rang.

Through the hidden surveillance video installed at the door, Xu Chuan saw a familiar figure. Halifax Bruce, director of the PPPL Plasma Laboratory in Princeton.

Seeing someone coming, he frowned slightly, locked the room where the materials were stored and walked out.

At the gate of the villa, Halifax Bruce, the director of the PPPL plasma laboratory, waited quietly and respectfully.

Regardless of age, the people living in this villa, even if they are placed in the United States, are the top talents.

Although the age of being too young makes people look down on it from the bottom of their hearts, in any case, there must be people who can solve the seven millennial problems.

What's more, he is asking for others now, and his posture must be put on a posture.

"Hello, may I ask who you are?"

Xu Chuan opened the door and looked at the man outside the door with a 'puzzled' expression.

Although he was very familiar with the director of PPPL in his previous life, it was the first time he had met in this life.

Seeing Xu Chuan, the pot-bellied Halifax Bruce had a bright smile on his face, as if he had seen a green Franklin.

"Hello, Professor Xu, I take the liberty of interrupting you, my name is Halifax Bruce, and I am the director of the PPPL Plasma Physics Laboratory at Princeton University."

Xu Chuan nodded and said, "Hello, Director Bruce, do you have anything to do with me?" ”

After putting the person in, Xu Chuan handed a glass of water to Halifax Bruce, no matter what, it must still be done.

"Yes, Professor Xu, we would like to invite you to join PPPL, the world's greatest plasma laboratory, whose mission is to lay the scientific foundation for the creation of fusion energy, power sources for the sun and stars......."

At the first meeting, Bruce briefly introduced the glorious history and famous achievements of the PPPL plasma laboratory, hoping to arouse Xu Chuan's interest.

Bruce pulled a lot, and Xu Chuan listened to it with a little desire to sleep.

As for the situation and future development of PPPL, he is not more familiar with the supervisor in front of him, nor is he much worse. After all, his theoretical research on controlled nuclear fusion in his previous life was carried out in PPPL.

"Professor Xu, at present, we are conducting plasma turbulence control experiments in PPPL and the Turbulence Laboratory of Purdue University, and we have invited Professor Feverman to join."

"At the same time, we would love to work with great scholars like you to control plasma turbulence."

Finally, Bruce ended his boasting of the great and glorious history and looked up at Xu Chuan expectantly. But when I saw the person opposite yawning and trying to sleep, my heart suddenly cooled.

Seeing that the other party had finished speaking, Xu Chuan yawned and said, "Professor Feverman looked for me this morning, and this is what you said." ”

"But I'm sorry, I'm not interested in nuclear physics, and I still have my own research going on here, so I can't spare time."

Bruce: "A million meters of gold a year!" It is enough for you to cooperate with Professor Fefferman to complete the data analysis work, and you do not need to come to work. ”

"You can take the job at Princeton and continue your research at the same time. It's not a conflict, it just requires you to put in some time once in a while. ”

Xu Chuan shrugged his shoulders and said, "It sounds tempting, but I haven't even received the one million meters of gold from the Clay Research Institute." ”

His words simply show that he is not short of money and does not care about it.

But in the ears of the director of the PPPL laboratory, it became "Gotta add money!" ”

"One million two hundred thousand! An annual salary of 1.2 million meters! As long as you agree, PPPL can prepay all your salaries in advance. Halifax Bruce gritted his teeth.

His heart is bleeding, and his annual salary of 1.2 million meters of gold is almost as good as inviting Fefferman, who is a Fields Medal winner with decades of scientific research experience.

If it weren't for the fact that Pfeiffman said he had to, and that the PPPL card had been controlling the temperature of the 10-million-level ion temperature gradient turbulence for some time, and now they urgently needed a new breakthrough to get the backroom financiers to continue to invest in them, he would not have been able to make such a number.

Xu Chuan smiled and said, "It's a pity, it's not about money, in my opinion, it's more appropriate to complete your own research than to waste time on a job where you don't see much hope." ”

......

Eventually, Bruce left disappointed, and after stepping out of the lawn, he turned his head to look at the villa behind him, and had a headache. He really couldn't understand why someone would refuse a full 1.5 million meters of gold.

All this money can be piled up on the ground to form a green mountain.

Shaking his head, Bruce let out a long sigh of relief, if money can't make the other party make a move, then what about other things?

Immigrating to become a citizen of the United States? The fame and fortune of the academician of the United States? Top research resources? Or status? Or something else?

It's just that these things are not up to him, and he has to go and discuss them with the top boss of PPPL Labs.

Of course, he also had to go to other professors in Princeton to find out about this Professor Xu Chuan's abilities.

If the young professor is really capable enough to solve the problem of controlling plasma turbulence, what does it matter if he pays a little benefit?

Compared with the gains brought by solving the plasma turbulence problem, the benefits paid are not a dime.

This is one of the biggest problems in controlled nuclear fusion, and the value of solving this problem cannot be described in terms of money.
