After Carlson received a reply from Lu Zhou, he didn't have any hope, and the Millennium Prize Problems award ceremony was put on hold.
However, someone leaked the news, and the news of the Clay Institute canceling the award ceremony spread like wildfire.
In the end, it became Lu Zhou refusing to accept the award.
Ever since the Navier – Stokes equation was solved, a lot of media outlets had been paying attention to the million-dollar reward for the Millennium Prize Problems. After all, for most people who didn't pay attention to mathematics, proving the existence of a Navier – Stokes equation was far less impactful than a million-dollar reward …
A reporter from The New York Times wrote an article.
[… After the Russian mathematician Perelman refused the million-dollar reward, Chinese mathematician Lu Zhou also refused the million-dollar reward. The Millennium Prize Problems seem to be surrounded by a mysterious curse, and the people who solve these problems eventually lose interest in money?]
When Lu Zhou took the newspaper from Hadi's hand, he finished reading it and threw it into the trash can. He shook his head and spoke.
"What a load of nonsense. When did I say I refused to accept the award? I just told the Clay Institute to wait because I'm very busy, and I don't have time to fly to Paris. "
Hardy: "Professor, did you turn down the Clay Institute's prize money because you didn't have time to accept the prize?"
Lu Zhou emphasized, "It's a delay."
Hadi shrugged and said, "Okay, it's a delay … Professor, I actually have a suggestion, but I don't know if I should say it or not."
Lu Zhou looked at him and said, "What suggestion?"
Hadi awkwardly scratched his head and said, "What I mean is, if you really don't have time, you can send me to Paris to accept the award for you. You're very busy with your research, but I don't mind traveling … "
Lu Zhou: "…"
This guy …
Has he been too free lately?
…
The rumors were just a small interlude for Lu Zhou.
He was busy with plasma turbulence research, so he didn't have time to hold a press conference to clarify these boring things.
Other than the award ceremony, the Navier – Stokes equation didn't only bring him too much attention from the media, but it also brought him trouble from other aspects.
For example, ever since he returned from Brazil with the Fields Prize, his mailbox had been filled with invitations from all over the world.
Some of them were from domestic and foreign research institutions, some were from a top 100 mathematics university, and some weren't even from academia at all. They were from a certain TV series or a certain talk show …
After leaving all these emails to Xiao Ai to deal with, Lu Zhou felt much more relaxed.
When it came to rejecting and dealing with spam, Xiao Ai was like a caring little cotton-padded jacket. After he demonstrated it a few times, he was getting more and more comfortable with it.
After arranging these trivial matters, Lu Zhou returned to his research work and began to study the plasma turbulence problem.
It was worth mentioning that there were two main types of turbulence problems.
The first type came from the complexity of the system and environment. This complexity came from the diversity of turbulent systems.
Take a spacecraft as an example. As the altitude, speed, and even the surface temperature of the spacecraft changed, the gas environment and macroscopic mechanical environment of the spacecraft would constantly change.
As for the second type of complexity, it came from the methodology of classical physics.
Traditional reductionism started from the most basic components of the motion of matter and established the evolution equation of motion from the interaction between the basic components. This sounded simple. After all, many formulas in classical physics didn't even require advanced mathematics.
However, in physics, "more is more complicated".
Take an aircraft as an example. The flow field around a Boeing 747 would contain 10 ^ 15 to 10 ^ 24 microfluidic elements. Even if all of the world's computers were used, it would be difficult to complete such a large amount of calculations.
Therefore, most of the models established by researchers who did fluid mechanics analysis were phenomenological. Different scholars using the same CFD method could even get completely different results.
Because of this, turbulence CFD calculations based on engineering closed theory were often referred to as "art" rather than science.
The reason why people were so obsessed with the existence and smoothness of the Navier – Stokes equation wasn't just because they wanted to know if the unsolvable solution existed. It was also because they hoped that mathematicians would be able to obtain something from studying this equation.
It might be a construct to calculate the boundary between the subsonic and sonic zones, or it might be an approximate weak form that was applicable in a limited range. As for what Lu Zhou obtained, it was the L Manifold and the differential geometry method for partial differential equations.
For the plasma inside the stellarator, the first type of problem was easy to solve. Although the plasma under high temperature and pressure was unstable, at least the mechanical environment of the entire plasma circulation was uniform on a macroscopic level.
As for the second type of problem, it was the core difficulty.
However, the difficulties here were only for ordinary people.
When Lu Zhou applied the L Manifold to the Navier – Stokes equation and built a mathematical model based on the differential geometry method, he found out that even though the whole process was complicated, it wasn't as difficult as he imagined.
Time quickly passed by, and a new page appeared on the calendar.
Early September.
Lu Zhou sat in his office at the Princeton Institute for Advanced Study. He stared at the computer screen and wrote on a piece of paper from time to time.
When he finished typing the last line of equations on the computer, he finally let out a sigh of relief and put down the ballpoint pen.
"Done!"
When Hadi heard the professor's voice, he looked up with a muddled expression. He looked at Qin Yue, who was next to him, and then he quietly lowered his head.
Jerick and Vera secretly looked at Lu Zhou with admiration. Especially Vera, Vera's eyes were sparkling like little stars.
Even though she didn't know what the professor was doing, she felt like it was amazing.
As for Wei Wen, he was writing his master's thesis, so he didn't care at all. For someone like Lu Zhou, who wanted to graduate this year and start his PhD next year, these things weren't important.
All in all, the professor was going to come up with something nutty again …
Lu Zhou didn't notice the students' reactions. He quickly checked his mathematical model and copied the data into a USB. He then quickly left the office with the USB.
The derivation of equations could be done by the human brain, but when it came to numerical solutions, the terrifying amount of calculations was beyond the scope of human capabilities.
In order to verify his mathematical model and collect first-hand simulation data, he needed a supercomputer.
The sooner, the better!
…
As the richest university in North America, Princeton's wealth was not only reflected in its ability to poach people, but it was also reflected in the construction of campus facilities.
Even though it was located in the small town of Princeton, it had everything from the plasma physics laboratory to the supercomputer center.
This showed how important it was for a university to have the support of a wealthy alumni association.
The campus supercomputer in Princeton was called the John Norman Supercomputer Research Center. It mainly did simulation research in condensed matter physics, plasma physics, celestial mechanics, and other aspects.
Even though Lu Zhou knew David Shaw, who was a genius in the field of parallel computing, Anton's powerful computing power was only reflected in the field of computational chemistry. Anton's performance in the general computing field wasn't ideal.
Not to mention that David Shaw wasn't necessarily interested in plasma physics or fluid mechanics, so Lu Zhou didn't bother him.
After Lu Zhou filled out the application form at Nassau Hall, he didn't have to wait for long. Soon, he received the approval from the university.
Any research project that was related to the PPPL was approved the fastest.
Not to mention that this was a Fields Award winner.
Lu Zhou brought the documents to the John Norman Supercomputer Center and found Professor Amer Green, the director of the research center. He then explained his intentions.
After Green heard Lu Zhou's request, he raised his eyebrows in surprise.
"Unbelievable … Are you sure you're not kidding? You successfully built a mathematical model for the plasma turbulence in the stellarator? "
Even though he wasn't a physicist, he knew how amazing this was.
Lu Zhou sighed and waved the application in his hand. He said, "There's still half a year until April Fool's Day. I'm sure I'm not kidding."
Professor Green didn't waste any time. He turned on his computer and said, "Do you have the model with you?"
Lu Zhou placed the USB on the table and said, "Of course."
Green took the USB and plugged it into the computer. He opened the file and looked at the data and images on the computer screen. He rubbed his chin and thought for a moment before he said, "Forgive me for being blunt, but this seems difficult. I'm not sure if our John Norman can handle this amount of calculations. I'm afraid you'll need the Oak Ridge National Laboratory's Summit … Is there no way to simplify this model? "
Lu Zhou shook his head and said, "This is the simplest I can do."
"Okay then, you've given us a difficult problem on behalf of the PPPL laboratory." Professor Green spun the pen in his hand and said, "I can solve the algorithm part, but don't expect this to be completed in a short period of time."
Lu Zhou nodded and said, "I know. Also, I'll provide you guys with help. "
