Scholar’s Advanced Technological System

After receiving a reply from Lu Zhou, Carlson basically had no hope, and the issue of the Millennium Challenge Award was put on hold.

However, I don’t know who leaked the news, and the Cray Institute’s cancellation of the original awards plan was passed down.

And finally passed on, it was passed Lu Zhou refused to accept the award.

Since the NS equation was resolved, many media have been paying attention to the one million dollar reward for the Millennium problem. After all, for most people who don’t care about mathematics, the existence of the NS equation is proven to be far less than a million dollars more shocking…

The New York Times reporter wrote an article.

[…After the Russian mathematics home Perelman refused to receive a one million dollar reward, the Chinese state mathematician Lu Zhou also rejected a one million dollar reward. The millennium puzzle seems to be lingering with a mysterious curse. The people who solved these propositions eventually lost interest in money. 】

When he took the newspaper from Hardy’s hand, Lu Zhou threw it into the trash can after shaking it, shaking his head.

“It’s a nonsense. When did I say that I refused to accept the award? I just let the Cray Institute wait, because I am very busy, and I can’t find time to fly to Paris again.”

Hardy: “Professor, are you pushing out the Cray Institute’s bonus because you can’t get the time to win the prize?”

Lu Zhou emphasized one sentence: “It is postponed.”

Hardy shrivugged helplessly: “Well, it’s postponed…Professor, actually I have a suggestion, just don’t know if it should be said.”

Lu Zhou gave him a look: “What advice?”

Sorry to scratch the back of the head, Hardy said with a smile, “I mean, if you really can’t find time, you can send me to Paris to receive the award for you. Your research is very busy, but I I don’t mind going out for a trip…”

Lu Zhou: “…”

This guy……

Is it too busy recently?

……

The rumors about the outside world are just a small episode for Lu Zhou.

He is busy with plasma turbulence research, and he has no time to open a press conference to clarify this boring thing.

In addition to the awards, the troubles brought by the NS equation are not just the media’s excessive attention, but also from other aspects.

For example, since he returned from Brazil with the Fields Medal, his mailbox has been filled with invitations from various places.

Some of them are from domestic and foreign research institutions, and some universities from mathematics subject global ranking top100, and some even from academic circles, but from a TV series and a talk show…

After throwing all of these messages to Xiao AI for processing, Lu Zhou felt a lot easier.

In terms of humanity rejection and dealing with spam, Xiao AI is just like his intimate little cotton jacket. After he has demonstrated it a few times, he is now more and more comfortable.

After arranging these trivialities, Lu Zhou continued to return to the research work and began research on plasma turbulence.

It is worth mentioning that the difficulty of turbulence mainly comes from two major types of problems.

The first category comes from the complexity of the system and the environment, which comes from the diversity of the turbulent motion system.

Taking spacecraft as an example, the gas environment and macroscopic mechanical environment in which the spacecraft is located are constantly changing with changes in flight altitude, speed, and even regional and material surface temperatures.

As for the second type of complexity, it is derived from the methodology of classical physics.

The traditional reduction theory starts from the most basic component of material movement, and establishes the evolution equation of motion from the interaction law between basic components. This sounds simple, after all, many of the classic physics formulas don’t even have to be used in advanced mathematics.

However, in physics, “more complex.”

Similarly, in the case of an aircraft, the flow field around a Boeing 747 will contain 10^15~10^24 microfluidic elements, perform mechanical analysis on each microfluidic element, and consider the disturbances between each other, even if It is also difficult to complete all such computers in the world.

Therefore, most researchers who do fluid mechanics analysis are all phenomenological. Different Scholars use the same CFD method and can even get very different results.

It is for this reason that turbulent CFD calculations based on engineering closure theory are often referred to as “art” rather than science.

The reason why people are so obsessed with the smoothness and existence of the solution to the NS equation is not only to know whether the solution that cannot be found exists, but to hope that the mathematics can study this equation. Get something.

It may be a structural quantity that calculates the boundary between the subsonic zone and the sonic zone, perhaps an approximate weak form that is applicable in a limited range. As for Lu Zhou, it is the L manifold and the differential geometry method to deal with the partial differential equation. .

For the plasma inside the imitation star, the first type of problem is better. Although the plasma in the high temperature state is unstable, at least the entire plasma circulation is uniform in the mechanical environment of the macroscopic components.

As for the second type of problem, it is the core difficulty.

However, the difficulties here are only for the average person.

When Lu Zhou applied the L manifold to the NS equation and built the mathematics model for those experimental data based on the differential geometry method, it was found that the whole work was full of complexity, but it was not as difficult as he imagined.

As time went by, the calendar opened a new page.

Early September.

Sitting in the office of the Princeton Institute of Advanced Studies, Lu Zhou was not allowed to stare at the computer screen, and the pen in his hand was written on paper from time to time.

When he knocked the last line of calculations on the computer, he finally put out a long breath and put down the ballpoint pen that was pinched at his fingertips.

“Get it!”

Upon hearing the voice of Professor, Hardy looked up and slammed his head, and looked at Qin Yue next to him, then silently lowered his head.

Jericho and Vera sneaked a sneak peek at Lu Zhou, especially the latter, whose eyes seemed to be twinkling with stars.

Although I don’t know what Professor is doing, I always feel very good.

As for Wei Wen, I am writing a master’s thesis, which is indifferent. For those who are interested in starting to read Bo next year, these things are irrelevant.

In short, Professor has also researched what is arrogant…

Did not notice the reaction of the students, Lu Zhou quickly checked his mathematics model, and then copied the data to the U disk, and quickly left the office with a USB flash drive.

The derivation of the equation is a work that can be done by the human brain, but once the numerical solution is involved, the amount of horrible calculations is beyond the reach of manpower.

In order to validate his mathematics model and also to collect first-hand simulation data, he now needs a supercomputer.

The sooner the better!

……

As one of the richest universities in North America, Princeton’s rich and imposing is not only reflected in the willingness to spend money, but also on the construction of campus hardware facilities.

Although located in its fascinating town of Princeton, it is everything from plasma physics labs to supercomputer centers.

It can be seen that there is a financially strong alumni association behind the support, how important it is for a university.

Princeton’s school super-calculation, known as the John Norman Supercomputer Research Center, is mainly used for simulation studies in condensed matter physics, plasma physics, and celestial mechanics.

Although among the people Lu Zhou knows, there is David Shaw, a cow in the field of parallel computing, but Anton’s powerful computing power is only reflected in the field of computational chemistry, and his performance in general computing is not ideal.

What’s more, David Shaw himself is not necessarily interested in plasma physics or fluid mechanics simulation, so Lu Zhou will not bother him.

After filling in the application form in Nassau Hall, Lu Zhou did not wait for a long time and quickly got the approval application from the school.

Any research project linked to the pppl lab is the most rapid.

Not to mention a Field’s Medal winner.

With a written document to the John Norman Supercomputer Center, Lu Zhou found the director of the research center, Amer Green, and explained his intentions.

After listening to Lu Zhou’s request, Green’s eyebrows picked it up in surprise.

“Unbelievable… Are you sure you are not kidding? Have you successfully built a mathematics model for plasma turbulence in a starburst?”

Although he is not a Physics home, he still knows how amazing this is.

Lu Zhou sighed, shaking the application in his hand: “There are still half a year from April Fool’s Day, I am sure I am not joking.”

Green Professor has no nonsense, and has opened the computer for work. “Do you bring that model?”

Put the USB flash drive on the table, Lu Zhou said: “Of course.”

After taking the U disk and plugging it into the computer, after opening the file inside, looking at the data and images on the computer screen, Green touch the chin on the chin, thinking for a moment, said, “I’m blunt, it looks very difficult. I’m not sure if our John Norman has the ability to withstand this magnitude of computing. What you need is the Summit of Oak Ridge National Laboratory… Is there no way to simplify this model?”

Lu Zhou shook his head: “This is the simplest form I can do.”

“Well, you have given us a problem on behalf of the PPPL lab,” Green Professor said, turning his pen and thinking for a moment. “The algorithm part I can solve, but you don’t expect this work to be in a short time. carry out.”

Lu Zhou nodded: “I know. And I will help you.”

Green said, with a smile: “This is a must. After all, we are doing massive parallel computing, not a plasma physics expert.”
