Scholar’s Advanced Technological System

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

However, it is not known who leaked the news, so the news of the Clay Institute canceling the original awarding program spread.

And finally passed on, it became Lu Zhou refused to accept the prize.

Since the NS equation was solved, 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 solution has been proven to be far less shocking than a million dollars ...

The New York Times reporter wrote a comment.

[... Following the refusal of Russian mathematician Perelman to receive a one million dollar reward, Chinese mathematician Lu Zhou also refused a one million dollar reward. The millennial puzzle seems to haunt a mysterious curse. Those who solve these propositions eventually lose their interest in money? 】

After receiving the newspaper from Hardy, after Lu Zhou finished reading it, he threw it into the trash can and shook his head.

"It's almost nonsense. When did I say I refused to accept the prize? I just let the Cray Institute wait because I'm busy and I can't afford time to fly to Paris recently."

Hardy: "Professor, did you push out the Clay Institute's prize because you couldn't make time to claim it?"

Lu Zhou emphasized: "It was postponed."

Hardy shrugged helplessly: "Well, it was postponed ... Professor, I actually have a suggestion, but I don't know if I should say it."

Lu Zhou glanced at him: "What advice?"

Scratching his head embarrassed, Hardy smirked and said, "I mean, if you really can't make time, you can send me to Paris to receive your award. Your research is busy, but I am Don't mind a long trip ... "

Lu Zhou: "..."

This guy……

Have you been too busy lately?

...

Rumors about the outside world are just an episode for Lu Zhou.

He is busy studying plasma turbulence, but he doesn't have time to hold a press conference specifically to clarify such boring things.

In addition to seeing the awards, the trouble caused by the NS equation is not just the excessive attention of the media, but also from other aspects.

For example, since he returned from Brazil with the Fields Award, his mailbox was stuffed with invitations sent from various places.

Some of them are from domestic and foreign research institutions, and some are from a university with a global top 100 ranking in mathematics. Some are not even from academia at all, but from a TV series and a talk show ...

After throwing all these emails to Xiao Ai for processing, Lu Zhou felt much easier.

In terms of humanized rejection and handling of spam, Xiao Ai is almost like his intimate cotton padded jacket. After several demonstrations, he has become more and more handy.

After arranging these trivia properly, Lu Zhou continued to return to his research work and began his research on plasma turbulence.

It is worth mentioning that the difficulties of turbulence problems mainly come from two types of problems.

The first type comes from the complexity of the system and the environment. This complexity comes from the diversity of turbulent motion systems.

Taking the spacecraft as an example, the gas environment and the macro-mechanical environment in which the spacecraft is located are constantly changing with changes in flight altitude, speed, and even the temperature of the surface of the material.

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

Traditional reductionism starts from the most basic components of material movement, and establishes the evolution equation of movement based on the laws of interaction between basic components. This sounds simple, after all, many formulas of classical physics do not even need advanced mathematical methods.

In physics, however, "more is more complicated".

Taking the aircraft as an example, the flow field around a Boeing 747 will contain 10 ^ 15 ~ 10 ^ 24 microfluids. Do a mechanical analysis of each microfluid and consider the disturbance caused by each other, even if it is With all the computers in the world, it is difficult to complete such a huge amount of calculations.

Therefore, most of the researchers who do fluid mechanics analysis are all phenomenological. The same CFD method is used by different scholars, and even different results can be obtained.

It is for this reason that turbulent CFD calculations based on engineered closed theory are often referred to as "art" rather than science.

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

It may be a tectonic quantity that calculates the subsonic zone and the boundary of the sonic zone. It may be an approximate weak form that is applicable in a limited range. As for Lu Zhou, it is the processing of partial differential equations by L-manifolds and differential geometry methods. .

For the plasma inside the stellar, the first type of problem is okay. Although it is said that the plasma under high temperature and pressure is unstable, at least the mechanical environment of the components of the entire plasma circulation is macroscopically uniform.

As for the second type of problem, the core difficulty lies.

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

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

As time passed, the calendar turned a new page.

Early September.

Sitting in the office of the Princeton Institute of Advanced Studies, Lu Zhou stared at the computer screen with imperceptibility, and from time to time he wrote and wrote on the paper.

When he typed the last line of calculations on the computer, he finally took a sigh of relief and put down the ballpoint pen between his fingers.

"Get it!"

Upon hearing the professor's voice, Hardy looked up aggressively, looked at Qin Yue next to him, and then lowered his head silently.

Jericho and Vera secretly cast their worship on Lu Zhou, especially the latter, as if little stars were shining in their eyes.

Although I don't know what the professor is doing, I always feel terrific.

As for Wei Wen, he is writing a master's thesis and is indifferent. For him who is interested in graduating this year and starting to read a blog next year, these things are irrelevant.

In short, the professor has developed something superb ...

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

The derivation of the equation is a task that can be accomplished by the human brain, but once the numerical solution is involved, the amount of horrible calculations exceeds the scope of human power.

In order to verify his mathematical model and 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 wealth is not only reflected in willingness to spend money to dig people, but also in the construction of campus hardware facilities.

Although it is located in the unpretentious town of Princeton, there is everything from the plasma physics laboratory to the supercomputing center.

This shows how important it is for a university to have a wealthy alumni association behind it.

Princeton's school supercomputing is called the John Norman Supercomputer Research Center. It mainly focuses on the simulation research of condensed matter physics, plasma physics, astronomical mechanics and so on.

Although among the people Lu Zhou knows, there is a bull in the field of parallel computing, such as David Shaw, but Anton's powerful computing ability 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 didn't bother him.

After Nassau Church filled out the application form, Lu Zhou did not wait long, and quickly received the school's approval application.

Any research project linked to pppl labs is approved the fastest.

What's more, a Fields Prize winner ~ www.wuxiaspot.com ~ came to the John Norman Supercomputing Center with written documents, and Lu Zhou found the director of the research center, Professor Amer Green, and explained to him Your own intention.

After listening to Lu Zhou's request, Green's eyebrows were raised in surprise.

"Unbelievable ... are you sure you are not kidding? You successfully built a mathematical model for plasma turbulence in a stellar?"

Although he is not a physicist, he still knows how amazing it is.

Lu Zhou sighed and shook the application in his hand: "It's still half a year before April Fool's Day. I'm sure I'm not kidding."

Professor Green didn't make nonsense. He turned on his work computer. "Do you bring that model?"

Putting the USB flash drive on the table, Lu Zhou said, "Of course."

I took the USB flash drive and plugged it into the computer. After opening the files inside, looking at the data and images on the computer screen, Green felt the scum on his chin and thought for a moment. "IMHO, this looks difficult .I'm not sure if our John Norman is capable of withstanding this order of magnitude calculations. What you need is Summit of Oak Ridge National Laboratory ... Is there no way to simplify this model? "

Lu Zhou shook his head: "This is already the simplest form I can do."

"Well, you have given us a problem on behalf of the PPPL laboratory," Professor Green said, turning his pen, and thinking for a moment. "I can solve the algorithm part, but you don't expect this work to take a short time carry out."

Lu Zhou nodded: "I know. And I will help you."

Professor Green said with a smile: "This is necessary, after all, we are doing large-scale parallel computing, but we are not experts in plasma physics."
