Chapter 208 The Tears of the Astronomical Community Flowed to the Mathematical Community

After seeing off Halifax Bruce, the director of the PPPL laboratory, Xu Chuan had a headache.

From the memory of his previous life, the PPPL plasma laboratory, which is directly under the jurisdiction of the U.S. Department of Energy, seems to have been studying how to control plasma turbulence in the past two years.

This also fits Bruce's purpose of coming to him, to control the modeling of plasma turbulence.

As for the specific progress and situation, he is not very clear, after all, when he conducted experiments at PPPL in his previous life, it was already after 2030.

Although he has seen some historical data of the PPPL laboratory, it has been a long time and he can't remember it clearly.

However, he can be sure that this research must have failed and been abandoned in the end.

After all, if it succeeds, the PPPL laboratory will definitely apply this technology, and he will definitely have a very clear memory.

After watching Halifax Bruce leave, Xu Chuan turned around and touched his mobile phone from the sofa, ready to buy a ticket to return home.

But when the ticket booking software was opened, he finally hesitated for a long time and then forked off the ticket purchase page.

Although he should return to China as soon as possible, it is not suitable now. He is still waiting for an opportunity, but he doesn't know if it will come.

Shaking his head, Xu Chuan calmed down and began to think.

His experience in his previous life made him a little panicked when he faced the nuclear physics application of this country again.

But in fact, if you think about it carefully, you will know that being approached by PPPL is not an urgent matter that requires him to buy a ticket back to China immediately.

According to the custom of this immigration country, if he wants to stay, then the senior executives of the immigration department must come to invite him personally, not the director of a laboratory.

This has something to do with the immigration policy of the United States. Top scholars like him are no longer restricted by ordinary immigration applications.

Even the highest EB-1A talent application in the US immigration policy is not worthy of his achievements.

For such talents, they are generally specially introduced by the immigration department.

For example, in March this year, Cao Yuan, a genius who completed the 1.1° angle superconductivity experiment of double-layer parallel graphene, was specially invited by the people of the US immigration department.

So if the United States really invites him to stay, it will probably be the people from the immigration office who come in person, not the director of PPPL.

Bruce came to him, most likely because he accepted Feferman's suggestion and wanted to invite him to work with Feferman on the control of plasma turbulence.

But now that he has rejected the invitation of 1.5 million MiGold per year, Bruce will go back and discuss with other senior executives and managers whether to increase the price and pay other costs to continue to invite him.

But according to the nature of the Americans, it is likely that continuing to increase the price will be rejected.

Because the Fields Medal winner Feferman has already accepted the invitation.

When a top mathematician has already accepted the invitation, it is not worth spending a lot of money to invite another mathematician.

The result is likely to be the same in any laboratory or company. The annual salary of 1.5 million MiGold is already very high. If it is increased again, who knows how much it will take to get him.

So according to speculation, PPPL Laboratory will definitely let Feferman try it alone first. If he can advance the work, he will not be invited again.

If Feferman can't advance, then PPPL will definitely come to him again.

So when will the next invitation be? It depends on Feferman's personal ability.

However, it is certain that Feferman is unlikely to solve this problem, even with the help of Purdue University.

On the one hand, the interim results of the NS equations cannot provide support for plasma turbulence modeling.

On the other hand, Feferman's physics ability is not good enough.

Xu Chuan knows the ability of this friend very well. Not to mention mathematics, he is a winner of the Fields Medal and a world-class expert.

He also has some ability in physics, but it is basically limited to the analysis of high-energy physics and particle physics, which he learned when working with the Fermi National Accelerator Laboratory.

In the field of fluid mechanics, although Feferman has been exposed to some because of his research on manifold mathematics, he has not been exposed to turbulence in depth.

In the previous life, when the two worked together, he taught them the knowledge of in-depth fluid mechanics bit by bit.

It is impossible to model plasma turbulence without knowing much about turbulence. Even with the assistance of turbulence experts from Purdue University, it is impossible.

If possible, he and Feferman would have solved this problem in the previous life.

If possible, he would never have to risk going to Princeton to study mathematics again in his life.

So it is certain that as long as PPPL does not give up the control of plasma turbulence, it will definitely come to him again in the future.

At that time, it will definitely offer more favorable conditions.

For example, help him immigrate, bonuses, profit sharing, income sharing, promises of academician honors and other things.

Although PPPL does not have such great power, its superiors do.

In order to retain a talent, this immigration country can offer conditions that many people dare not even think about.

As for when to come to him, it depends on Feferman's ability.

However, according to his understanding of Feferman, this time may be about two to three months.

After thinking about these things clearly, Xu Chuan breathed a sigh of relief and felt a little relieved.

I have to say that Fefferman, his lifelong friend, really scared him this time, so scared that he almost bought a ticket and ran away.

Of course, the blame cannot be placed on Fefferman’s head.

Instead, he had to thank his good friend.

Without the ideas and ideas brought by Fefferman, we don’t know how long it will take to produce this phased result of the NS equation.

One of his purposes in coming to Princeton in this life was to seek to establish a mathematical model for ultra-high temperature plasma turbulence in a controllable nuclear fusion reactor.

Now that he has this initial result, he can take at most two steps forward and start modeling attempts.

Once he has figured out the control model of plasma turbulence, and combined with the superconducting materials, dual magnetic mirror systems and other things he developed in his previous life, he can try to launch a charge towards controllable nuclear fusion.

Although issues such as first wall materials and tritium self-sustainment are still not clear, as long as the ultra-high temperature plasma in the reactor chamber is controlled, the remaining troubles will be far less big.

It's like taming a wild horse. The first thing you have to do is put the reins on it.

As long as the reins are on, there is a certain chance of taming it.

However, before trying to tame this wild horse, he had to go back.

Fortunately, he has never entered the field of applied science in his life.

Research in pure theory and basic science has not been paid too much attention by this country in the current year.

If he waits 20 or 21 years later when this country begins to block talents in the field of basic science, he will definitely not be able to go back with his current achievements.

As for now, there is still enough time. He should still be able to leave before formally rejecting the immigration invitation and breaking his face.

In fact, at this moment, Xu Chuan probably had some speculations in his mind as to why there had been no movement from the United States, including his home country, and no one from the immigration office or talent introduction organization had come to look for him.

However, this speculation will take some time to be verified.

After returning to normal life, Xu Chuan focused his time on teaching his four students and continuing to make breakthroughs in the NS equation.

However, there was no liver-breaking research this time. It was just a follow-up attempt on the NS equation, and the main focus was not even on this.

The days passed like this little by little, and in the blink of an eye, the time came to the end of June.

As he had expected, the PPPL Physics Laboratory did not come to him again in the past ten days, and Fefferman also disappeared in Princeton.

Obviously, PPPL Laboratory finally chose a more ‘saving’ method.

After all, the annual salary of 1.5 million meters is terrifying enough, and if it continues to increase, no one knows how much it will cost to invite the young genius.

What's more, Xu Chuan's age is there. He is in his early twenties, and even though he has great achievements in mathematics, he does not have enough scientific research experience.

Whether it is worth spending a huge price to invite him, even with the endorsement of Fefferman, a Philippine Award winner, is still uncertain.

In comparison, it is undoubtedly safer to let Fefferman try it alone.

This also allowed Xu Chuan to further confirm his suspicion.

At the end of June, on this day, Xu Chuan was explaining the 'algebraic varieties and group mapping' tool to his four students, when his mobile phone vibrated in his pocket.

Xu Chuan stopped explaining, took out his phone and took a look. The number looked familiar, but he couldn't remember where he had seen it before.

After the call was connected, the voice on the other end came over: "Hello, Professor Xu Chuan, I am Martin Gleicher, Secretary General of the International Mathematical Union."

Some familiar voices made a figure who looked like a bald eagle immediately appear in Xu Chuan's mind. He smiled and said: "Hello, Secretary-General Martin."

Martin Gleicher, executive committee member and secretary-general of the International Mathematical Union, is a German mathematician, but his inverted V-shaped eyebrows and aquiline nose, coupled with his sharp eyes, make him look like the bald eagle, the national bird of the United States. Quite similar.

However, completely contrary to his appearance, Martin has a very easy-going personality and once promoted the 2006 International Mathematics Congress in China.

Prior to this, he had received a call from the Secretary-General in April, inviting him to attend the International Mathematical Union Congress and give a one-hour report at the meeting.

"I hope the call did not disturb your research." Martin Glecher said with a smile on the phone: "I am calling you this time to invite you to give a sixty-minute report at the International Mathematics Congress."

Hearing this, Xu Chuan was a little confused: "A one-hour report? But I remember that I agreed to it last time, and I have already submitted the report papers."

Martin Glecher explained: "This sixty-minute report is an additional invitation."

"Due to your previous expansion of the Xu-Weyl-Berry theorem, scholars in the astronomy and astrophysics circles are eager for you to explain it in detail. After receiving letters from many well-known scholars, and after discussions by the committee, I would like to invite You will give an additional report at this mathematics conference.”

Xu Chuan was stunned for a moment, a little confused, and asked hesitantly: "The astronomy community and the astrophysics community are writing to you? Invite me to hold a mathematics report? What's going on?"

Martin Grecher shrugged and said: "Yes, they said they have sent you many emails and made many phone calls. They would like to ask you to explain the extended application of the Xu-Weyl-Berry theorem, but You keep putting it off because you don’t have time.”

"Many scholars who study astronomy find it difficult to use your expanded Xu-Weyl-Berry theorem freely, so they eagerly hope that you will hold a few more lectures."

After a pause, Secretary-General Martin then joked: "What can make three Nobel Prize winners in astrophysics and more than twenty top scholars in non-mathematical fields unite to write to the International Mathematical Union, please ask a mathematician You are the first person to give a mathematics report since the establishment of IMU, and it is probably a miracle that will never happen again.”

"In addition, Professor Sal Perlmutter wanted me to tell you that if you take the stage this time to report on the expanded application of the Xu-Weyl-Berry theorem, he will write to the Nobel Prize Committee every year until you to win the Nobel Prize.”

Three Nobel Prize scholars and more than 20 top scholars jointly wrote to IMU. IMU could not ignore this application no matter what.

Moreover, it is the responsibility of IMU to promote international cooperation in mathematical research and encourage and support international mathematical activities that contribute to the development of mathematical science.

The International Mathematical Union will definitely find ways to promote this kind of report meeting that will help expand the influence of mathematics.

"Forehead".

Hearing Martin's explanation, Xu Chuan paused for a moment, with an embarrassed expression on his face and a bit confused about whether to laugh or cry.

After the secretary-general's reminder, he finally remembered the emails that had been casually dealt with in the mailbox in the past, and the phone calls he had casually answered.

However, he really didn't expect that all the casual rejections in the past would actually go to the International Mathematical Union (IMU).

Although he didn't care about the results in the astronomical world, he was too embarrassed to refuse anymore when things got to this point.
