Chapter 207 The tears of the astronomical world flowed to the mathematical world
After sending away Halifax Bruce, the director of PPPL Laboratory, Xu Chuan had a headache.
Judging from the memories of the previous life in my mind, the PPPL Plasma Laboratory, which is under the direct jurisdiction of the U.S. Department of Energy, seems to have been studying how to control plasma turbulence in the past two years.
This is also in line with the purpose of Bruce coming to him, to model and control plasma turbulence.
As for the specific progress and situation, he is not very clear. After all, when he conducted experiments in PPPL in his previous life, it was already after 2030.
Although he had seen some historical data from the PPPL laboratory, it had been a long time and he couldn't remember it clearly.
However, he is certain that this research must have failed and been abandoned in the end.
After all, if it succeeds, 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 picked up his cell phone from the sofa, preparing to buy a ticket to return home.
But when the ticket booking software opened, he finally hesitated for a while and then closed the ticket purchase page.
Although he wanted to return to China as soon as possible, now was not the right time. He was still waiting for an opportunity, but he didn't know if it would come.
Shaking his head, Xu Chuan calmed down his emotions and began to think.
The experience in his previous life made him a little panicked when he faced the application of nuclear energy physics in 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 to return home immediately.
According to the custom of this immigration country, if you want him to stay, the executive of the immigration ju will come and personally invite you, 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 subject to ordinary immigration applications.
Even the highest level of EB-1A talent application in the US immigration policy is not worthy of his achievements.
For such talents, the immigration judiciary is usually specially introduced.
For example, in March this year, the genius Cao Yuan, who completed the 1.1° angle superconducting experiment on double-layer parallel graphene, was specially invited by the American immigrants.
So if the United States really invited him to stay, it would probably be someone from the immigration office who would come in person, not the director of PPPL.
Bruce came to see him, most likely accepting Fefferman's suggestion and wanting to invite him to study the control of plasma turbulence with Fefferman.
But now that he has rejected the invitation with an annual salary of 1.5 million meters, Bruce will go back to discuss with other senior executives and managers to discuss whether to increase the price and pay other costs to continue inviting him.
But according to the old urine in the United States, there is a high probability that continuing to increase prices will be denied.
Because Philippine Prize winner Fefferman has 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.
If you apply this to any laboratory or company, the result will most likely be the same. The annual salary of 1.5 million meters is already very high. If you improve it, who knows how much effort it will take to get it done.
Therefore, it is speculated that PPPL Laboratory will definitely let Fefferman try it alone first. If the work can be advanced, there will be no need to invite him again.
….
If Fefferman can't move forward, PPPL will definitely come back to him again.
So when the next invitation will be, it depends on Fefferman's personal ability.
But what is certain is that Fefferman will most likely not be able to solve this problem, not even with the help of Purdue University.
On the one hand, the phased results of the NS equation cannot provide support for plasma turbulence modeling.
On the other hand, Fefferman's physical abilities are not good enough.
Xu Chuan couldn’t be clearer about his friend’s abilities. Let’s not talk about mathematics. He is the winner of the Philippine Prize and the world’s top university.
ox.
I also have some abilities in physics, but they are basically limited to the analysis of high-energy physics and particle physics, which I learned while working with the Fermi National Accelerator Laboratory.
As for fluid mechanics, although Fefferman had some contact with it because of his study of manifold mathematics, he did not go in depth and had basically no contact with turbulence.
When the two of them collaborated in a previous life, he taught him bit by bit the in-depth knowledge of fluid mechanics.
Without knowing much about turbulence, it is impossible to model plasma turbulence. Even with the assistance of turbulence experts from Purdue University, it cannot be done.
If possible, he and Fefferman had already solved this problem in a previous life.
If possible, he would never need to take the risk of going to Princeton to study mathematics again in his life.
So what is certain is that as long as the PPPL laboratory does not give up control of plasma turbulence, they will definitely come back to him later.
More favorable terms will definitely be offered at that time.
Such as helping him immigrate, bonuses, profit sharing, income sharing, promising academician glory and other things.
Although PPPL Laboratory does not have such great energy, its superiors do.
In order to retain a talented person, this immigration country can offer conditions that many people would never dare to think of.
As for when to come find him, this depends on Fefferman's ability.
But according to his understanding of Fefferman, 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 calmer.
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.
On the contrary, he has to thank this good friend.
Without the ideas and ideas brought by Fefferman, we don’t know how long it would have taken for this phased achievement of the NS equation to be produced.
One of his purposes in coming to Princeton in this life is to seek to establish a mathematical model for ultra-high temperature plasma turbulence in controllable nuclear fusion reactors.
This chapter is not over yet, please click on the next page to continue reading! Now that he has achieved this initial result, he can take at most two steps forward and start modeling.
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 charge towards controllable nuclear fusion.
Although the problems of 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 until 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 he formally refuses the immigration invitation and breaks 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 devoted his time to teaching his four students and continuing to make breakthroughs in the NS equation.
However, there is no liver-breaking research this time. It is just a follow-up to the NS equation.
Just trying, not even the main focus is on it.
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, in the past ten days or so, the PPPL Physics Laboratory did not come to him again, and Fefferman also disappeared in Princeton.
Obviously, PPPL Laboratory finally chose a more 'saving and cost-effective 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 that young genius.
What's more, Xu Chuan's age is such that 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 Prize winner, is still uncertain.
In comparison, it is undoubtedly safer to let Fefferman try it alone first.
This also allowed Xu Chuan to further confirm his suspicion.
...
At the end of June, on this day, Xu Chuan was explaining "algebraic varieties, group mappings, and tools" to his four students when his cell 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 Glecher, 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 Mathematical 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-eyl-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 discussion 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 and astrophysics communities are writing to you? Are you asking me to hold a mathematics report? What's going on?"
Martin Glecher shrugged and said: "Yes, they said they have sent you many emails and made many phone calls. They want to ask you to explain the extended application of the Xu-eyl-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-eyl-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 a letter to the International Mathematical Union, please ask a mathematician
You are the first person to give a math report since the founding of IMU, and you are probably a miracle that will never happen again in the future."
[The problem of slow update of new chapters will be resolved soon.
ann., View the latest chapters of this book on multiple sites at the same time.]
"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-eyl-Berry theorem, he will write to the Nobel Prize Committee every year until you
Until you 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 conference that will help expand the influence of mathematics.
"Forehead......".
After hearing Martin's explanation, Xu Chuan paused for a moment, his expression was awkward, and he was a little 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 achievements in the astronomical world, he was too embarrassed to refuse anymore when things got to this point.
