In the hotel room, Xu Chuan's eyes moved.

I have to say that the various benefits attached to this invitation are indeed exaggerated.

The salary was doubled by 2 million meters, the house and car were allocated, the corresponding scientific research funding resources, the right to use various large-scale scientific research equipment, the title of national academician, and the immigration of three generations of relatives......

For talents, the United States is indeed eager to find it.

Even if it's a Fields Medal winner, that's exaggerated enough.

It can be said that a Nobel laureate in the Department of Applied Sciences is invited, and the conditions and treatment are probably just like this, while a Nobel Prize winner who is not an applied theory may not necessarily have such a high salary.

But no matter how good these things are, it is not his homeland, his home, in the land where he has lived for twenty years.

Pretending to be a little shocked, Xu Chuan swallowed his saliva and still didn't speak.

On the other side, Andre Millier smiled, judging from the performance, the young genius was a little tempted.

They have investigated that Xu Chuan is just a student who came out of a poor family in the countryside, with no background, his family is poor and not rich, and he relies on his personal talent and hard work to have today's glory.

This kind of person is the most suitable for the United States, and it is also the easiest to be persuaded to move.

After a pause, he continued: "Professor Xu, I believe that in the United States, you can give full play to your talents, and there are the top scholars in the world here. Whether it's mathematics, physics, or astronomy, there are countless top talents. ”

"In addition, we have the world's best scientific research equipment, which can help you achieve your dreams."

"I believe that there is no country more suitable for you than the United States."

On the other side, Feverman also smiled and said, "Xu, welcome over, I believe you have a good life in Princeton." Maybe we can solve the ns equation together. ”

Xu Chuan was silent for a moment, as if thinking about the pros and cons, and only after half a sound did he say with some difficulty: "I need to think about it." ”

Andre Miller smiled: "Of course it's fine, hopefully one day we can work together." ”

He didn't let Xu Chuan make a decision now, after all, immigration is not a trivial matter.

However, he also believed that no one could resist such a temptation, and in the end the young genius would fall into their arms.

Xu Chuan nodded, turned around and left without speaking.

In the room, Andre got up and chased after him, stuffed a bag of tea into Xu Chuan's hand, and said with a smile: "Professor Xu, this is for you, and it is a waste to put it in my hand." ”

Xu Chuan took the tea and said, "Thank you." ”

......

Xu Chuan left, and in the room, Andre and Peverman continued to communicate.

"It looks like we're going to have another talent soon." Andre smiled and took a sip of the tea in the cup, then frowned: "This one is really not delicious, far worse than our coffee." ”

Feverman glanced at the door and said, "Hopefully, Professor Xu is a real genius, and if he can continue on the academic path, his future achievements are expected to surpass Gauss or Newton." ”

He was a little puzzled by Xu Chuan's performance today, in his impression, Xu Chuan was a person with his own ideas, basically not very entangled, but today he was a little screwed.

But he didn't think much about it, after all, immigration is a big deal, and it's normal to be entangled and hesitant.

Of course, he is not Andrei's lobbyist, it doesn't matter to him whether Xu Chuanjia joins the United States, and it is unlikely that the people of the United States can have a strong sense of family and country.

This is the most typical country of immigrants, and he himself is not a traditional American himself, and his parents are immigrants from Germanic countries.

Xu Chuan can join the United States, and he is looking forward to it, and the NS equation may be solved with him; It's normal not to join, and not everyone is willing to emigrate.

Andrei was a little surprised, and said: "You have a really high opinion of him, the former Schultz is only the successor of Grothendieck, surpassing Newton and Gauss, can he afford it?" ”

Feverman nodded seriously and said, "He's better than anyone I've ever met, and maybe he can move the times." ”

Andre shrugged his shoulders and grinned, "But if it's not in our great country, it doesn't make any sense. ”

......

In the elevator, Xu Chuan pinched the tea leaves in his hand, with a smile on his lips.

The price of this bag of tea in his hand is probably not cheap, at least in four or five figures. Because even if he doesn't drink much tea, he can clearly feel the difference between the cup of tea just now and the previous one.

It's such a good thing to leave it to the old man of the United States.

An exchange, earned a bag of tea, not bad, anyway, nothing was lost.

With the tea, Xu Chuan returned to the hotel in a happy mood.

The International Congress of Mathematics is just two days away, and some other things should be arranged.

Back at the hotel, Xu Chuan made a phone call to Princeton's two mentors, Deligne and Witten, to make an appointment to meet.

"Have you already decided?"

In a café opposite the venue where the International Mathematical Congress was held, Deligne looked at Xu Chuan and asked.

Xu Chuan nodded and said, "Well, I've decided to go back." After this International Congress of Mathematics, I left. ”

"As for my four students, I will tell them, if they are willing to go to China with me, I will still take them, and if you want to stay in Princeton, I will trouble you, tutor."

Deligne nodded and said, "This is not a problem, but you and Fefferman are not working together on the NS equation?" Leaving now, what about the NS equation? ”

Xu Chuan said with a smile: "The ns equation is not so easy to solve, if it is simply to prove that its solution exists and is smooth, maybe I still have a glimmer of hope for a few years of cooperation with Pfeiffman, but I am afraid that it will not be possible to calculate its solution in a short time." ”

On the side, Witten asked curiously, "Are you going back to preside over the matter of Huaguo's accession?" ”

Hua Guo joined, he knew it, and Xu Chuan still had a lot of credit in this.

Although he has not been there for a long time, his performance has been quite impressive.

Whether it is the solution of the proton radius puzzle problem or the method of using mathematics to calculate the energy level channel of physical particles, it is a hot topic and a world-class problem.

Xu Chuan shook his head and said, "I shouldn't be responsible for this, these things have nothing to do with me, at most, when I need to do research, I will go through the channel on the Huaguo side to apply for the right to use LHC and other equipment." ”

"And what are you going to do when you get back?" Witten asked in surprise, he thought that Xu Chuan was going back to preside over related matters.

Xu Chuan thought for a while and said, "On the one hand, I will continue to study mathematics, and on the other hand, I may expand to physical materials."

"When I was a student at NTU, my supervisor was a researcher in the field of physical materials, and I was quite interested in this aspect."

In front of Deligne and Witten, Xu Chuan didn't care about revealing his future development.

These two people, although they are both scholars in the United States, basically do not participate in political affairs, in the previous life he was eager to go back, Deligne and Witten have been helping to persuade and support.

Some scholars in Princeton are still relatively pure, not like those who came out of Harvard and Yale, and many of them have some political ideas.

Including Feverman, who came to him with the director of the immigration office, actually didn't care about this aspect of things.

This has something to do with the core of the Institute for Advanced Study in Princeton since its inception.

It is a research institute that brings together the best scholars in various fields to do the purest cutting-edge research, without any pressure from teaching assignments, research funding, or sponsors.

Hearing this, Deligne raised his eyelids, looked at Xu Chuan and said, "If you still want to study mathematics, Princeton is actually a very good place." ”

"If you're worried that some people are going to interfere with you, you don't have to, the people at the Institute for Advanced Study at Princeton have always come and gone and never do anything."

Xu Chuan smiled, the Princeton Institute for Advanced Study is indeed the case, but it is not necessarily the case in the United States.

Seeing that he didn't speak, Deligne sighed and said, "Forget it, you have always had your own ideas, and you are very firm; But I still want to say that even if you go back, I hope you can focus on math and don't waste your talent. ”

Xu Chuan nodded vigorously and said seriously: "Don't worry, mentor, I will continue to move forward." ”

"Go ahead, I'll talk to Witten for a while." Deligne waved his hand, he knew the character of his student, the kind that would not look back after making a decision.

It's just a pity, if he goes back, in that country, I'm afraid there won't be as good an academic environment as Princeton, and I don't know how far he can go in the future.

After teaching for decades, he has seen many outstanding Chinese students, and when he was in Princeton, these students showed excellent talent and even made a lot of achievements, but after he returned, he rarely heard of these people.

I have to say that this is a very regrettable thing.

I just hope that this student can avoid those things and go further academically.

......

After meeting with the two tutors, Xu Chuan called the four students over again and told them about their preparations to return to China.

"Teach, Professor, you're going back?"

Hearing the news, the four students were stunned, and they didn't speak for a long time with their mouths open, and finally it was the older Roger Dean who came back to his senses and asked.

It's shocking.

None of the four of them expected that their mentor would run away.

After all, after being together for a few months, the four of them never felt any thoughts of leaving Princeton in Xu Chuan.

And, what will they do after Xu Chuan leaves Princeton?

During the doctoral study, the supervisor resigned and ran away, is it a very bad thing, okay?

You'll need to consider and weigh various factors for yourself, including where you want to graduate from, whether your degree and credits can be transferred to a new school, what this new university is like, and the financial and personal academic impact of this.

Xu Chuan nodded and said, "Yes, I'm ready to return to China." ”

"As for you, don't worry; If you are willing to come with me to China, I welcome you, after all, you have been studying with me for a few months. ”

"If you want to stay at Princeton, you can choose one of them, Professor Deligne or Professor Witten, and they'll both accept it. I've told them about it, and they're willing to accept you. ”

"Of course, if you have other ideas in mind and want to follow other mentors, you can tell me and I'll help you find them."

"It's early August, and it's Princeton's fall intakes, so I don't think it will delay you too much."

"After all, you follow me to study, what you learn is some basic knowledge, you have not participated in any scientific research experimental projects, and you are not finalized, presumably many mentors are willing to accept you."

Hearing this, Gu Bing, Shaxi, Roger, and Amelia glanced at each other, not knowing how to choose.

They never imagined that they would encounter such a thing as a resignation from their mentor and running away during their PhD.

Moreover, the solutions proposed by Xu Chuan are also difficult for people to choose.

It was a good choice to go to Huaguo with Xu Chuan, after all, their mentor was now a Fields Medal winner, or the record-breaking kind.

And to transfer with a mentor, this is what most people in academia consider to be the "best choice".

The culture of academia sets the expectation that graduate students should be willing and willing to do whatever their supervisors expect.

This idea comes from a number of sources.

For example, your mentor has invested in you and is willing to continue to invest in you; Or you have already established a good way of communication and guidance with your supervisor, and it will be easier to stay with them for future study and research; Or maybe you should be willing to make any sacrifice to advance your career, be grateful to your mentor for their dedication to you, etc.

But there are some drawbacks to this option.

For example, moving to a new school can bring more stress and financial costs to students. For example, the readaptation of partners, social and cultural changes, changes in the cost of living, and changes in tuition fees.

Especially now, their mentor is going to return to China from the United States, and the customs and habits of the two countries are completely different.

In addition, the second option given by Xu Chuan, to stay at Princeton to continue his studies, is also a good choice.

As Xu Chuan said, it is the fall semester at Princeton, and they originally didn't enroll until this time, but it was only because of Xu Chuan's request that they came to study in advance.

The second is that Deligne and Witten are both Fields Medal winners, especially Deligne, who is also Xu Chuan's mentor, who follows the professors who have been passed down from generation to generation, and does not have to worry about future learning problems at all.

As for Witten, the four of them also knew that this was left by Xu Chuan to Amelia, after all, she had studied physics before.

But the other professors at Princeton, the four of them basically didn't think about it.

Who else could be better at Princeton than Deligne or Witten?

I'm afraid not.

Even if it's Peverman, it's at most comparable to the two.

The four of them were very confused and didn't know how to choose.
