[Hello dear Professor Lu Zhou, I'm Professor Kreber from the Spiral Stone 7-X Laboratory, we met at about this time last year, I don't know if you still have an impression. 】

[I am writing this letter for no other purpose, but I just want to thank you on behalf of the Max Planck Institute for Plasma Physics, all the scholars working in the field of controlled nuclear fusion, and ITER.] 】

[In fact, just last month, we completed the installation of the water-cooled deflector, but the end result was not as good as we expected. 】

[Fortunately, we received an invitation to review PRX at that time, and according to the mathematical model you provided, we redesigned the algorithm of the main control computer and adjusted the control scheme. Then, a miraculous scene appeared! 】

[You can't imagine how surprised we were at the time, the ribbon plasma running along the track was at least 50% more stable than before!] 】

[I believe that if we continue to improve the control scheme and improve the sensitivity of the current control unit of the toroid, this number can be even greater.] There is still a lot of room for use in your mathematical model, but due to limited technical conditions, we can't fully develop it for the time being. 】

[We will present the improved algorithm at the next IAEA-Demo International Symposium.] If you're interested, I can get you an invitation. Of course, if you don't have time to participate, you can also pay attention to the paper information on the official website. 】

[In any case, I have to say thank you to you, and I believe that many people, many people have to say thank you ......]

After reading this email, Lu Zhou's expression was a little strange.

There is such a coincidence.

The reviewer happens to be Professor Kreber?

But think about it, the circle of controlled nuclear fusion is so big, and the research of stellarators is dominated by the Spiral Stone-7-X laboratory, and he can't think of a more suitable reviewer except for Professor Kreber.

It's just that I heard that it's not easy to turn on the stellar simulator once, and it's burning money in milliseconds.

In this way, this is probably the most expensive review since PRX's inception......

At this time, Jimmy came from the lawn next to him.

"What's wrong, Professor?"

"It's nothing," shook his head, and Lu Zhou, who was standing by the lake, put away his mobile phone, "I have something to do, so I'll go back first." It's the last game of your college career, so keep it up. ”

"That's for sure!" Jimmy smiled brightly and continued in a joking tone, "I'm going to come back with another trophy before I graduate." ”

The training of the drone club continued, and after saying goodbye to the members of the club, Lu Zhou went straight back to the office of the Institute for Advanced Study.

Just as he arrived at the office, Vera was coming in from outside with a stack of papers.

When she saw that Lu Zhou was also here, the little girl's eyes lit up and she reported to him.

"Professor, this is the resume of the students who will enter next spring, and I have already printed it out for you."

Lu Zhou nodded: "It's hard work, just put it on my desk." ”

Speaking of which, it will be the end of the year in a few months.

If nothing else, he should be drinking coffee at this time, picking and choosing a few good-looking resumes from this pile of A4 paper, and then take a time for afternoon tea for a video interview, and finally decide who is the "lucky one" who can receive his offer.

However, this year, he does not plan to recruit any new students.

First, I can't get busy.

Second, after this batch of students graduated, it was almost time for him to think about returning to China.

Vera said embarrassedly, "Do you need to help you sort it out?" ”

Lu Zhou smiled and said, "No need, I'll take the time to take a look at it myself." ”

"Okay then."

Seeing that Lu Zhou didn't need help, Vera nodded, returned to her desk, and went about her own business.

Sitting not far away, Wei Wen glanced at the stack of resumes that Lu Zhou hadn't touched at all, and suddenly asked, "Aren't you recruiting new students this year?" ”

Lu Zhou: "Don't recruit it, you can't bring it." ”

Wei Wen nodded thoughtfully, did not speak, but understood something in his heart.

It seems that I have to step up my graduation thesis......

Shaking his head, Wei Wen put aside his distractions and put his energy back into the work at hand.

……

The latest paper published in PRX has caused a sensation in the plasma physics community.

Not just the plasma physics community, to be precise. As far as the content of this paper is concerned, its influence has spread to many fields such as applied mathematics, fluid mechanics, and even hydrology and meteorology.

Prior to this, turbulence was recognized as a chaotic system, and plasma turbulence was one of the most complex turbulence problems.

For Lu Zhou's paper, the vast majority of scholars engaged in research in related fields expressed a considerable degree of surprise.

Because it was so unexpected.

Or to put it another way, if it weren't for Lu Zhou's solution to the millennial puzzle of the NS equation, and if it weren't for the fact that it was a well-known scholar with a good reputation who claimed the discovery, most people would have preferred to believe that it was just an April Fool's joke.

Due to the large number of complex mathematical methods contained in the paper, it is difficult for people who do not have a foundation in differential geometry and partial differential equations to understand the paper, and even if they have a good mathematical foundation, they must refer to Lu Zhou's previous L manifold paper published in the Annals of Mathematics for reading.

However, when those who are interested read the paper and really understand the connotation, they are immediately shocked by the mathematical methods used in it.

Just like Robert Clarinan half a century ago. Kraichnan completed the only self-consistent first-principles energy spectrum equation for pulsating structures based on the conservation of momentum (DIA theory) when he used quantum field theory to perform a statistically closed study of the turbulent pulsating field energy equation satisfying the Navier-Stokes equation, thus creating the "modern turbulence analysis theory".

Lu Zhou's work is, in a sense, similar to his, and even further in degree.

And before that, no one had ever thought that the turbulence problem could be solved in this way!

After the paper was published, in less than half a month, it caused a considerable degree of sensation in the academic community.

In the latest issue of Physical Review Letters (PRL), Dieter Hoffmann, an internationally renowned plasma physicist and former dean of the School of Nuclear Physics and Science at the Technical University of Dam, Germany, was published. Prof. Hoffmann was invited to write a review article expressing his views on the paper, which shook the industry.

“…… The idea he used to build a mathematical model was unique, but the theoretical tools he used were not innovative, after all, the L manifold he created had been published in the Annals of Mathematics a few months earlier, and was later used to study the solution of the NS equation. ”

"In general, it is the job of physicists to generalize mathematical methods to the field of physics. And when a reliable tool is created, it's only a matter of time before it's used in the right place. ”

"If it weren't for this paper, a similar approach would probably be in five or ten years. And the same scene should have happened five or ten years later. ”

"Only now, he's telling us, and he's pushed it all forward by a decade."
