Section 243

If Xiao Yi hadn't thought of coming up with this thing first, and had directly approached them to set up this organization and seize the initiative.

Otherwise, it would probably be foreign countries that seized the initiative.

Chapter 215 Greenwald limit increased by 35%!

Chapter 215 Greenwald limit increased by 35%!

As time passed, the existence and smoothness of the solution to the NS equation gradually spread throughout the academic community.

When the mathematics community was celebrating, a view suddenly began to spread from the physics community.

[Xiao Yi should be a physicist with good mathematics, so the two millennium problems he solved are both related to physics. ]

And for this view, the vast majority of people in the physics community agree with it, so much so that quite a number of scholars and students in the physics community have begun to express their support for this statement.

After all, whether it is the NS equation or the mass gap problem, they are indeed problems that are deeply related to physics.

So Xiao Yi is a physicist, which is reasonable.

Of course, this naturally caused many scholars and students in the mathematics community to refute.

Are you kidding me? Just because I study a few physics problems, I become a physicist?

Xiao Yi is obviously a mathematician with a good family background.

Suddenly, people from both sides started a war of words on the Internet.

[It is obvious that Xiao Yi is a physicist first and a mathematician second. Otherwise, among the seven major problems of the millennium, he would not have solved the NS equation problem and the mass gap problem first, but the Hodge conjecture and the Riemann conjecture. ]

[It is hard not to support it. Finally, someone came out to say this. In the past, people always thought that Xiao Yi was a mathematician. What a joke! Compared with mathematics, among the achievements made by Xiao Yi, it is obvious that the achievements in physics are greater than those in mathematics. ]

[Humor, I think this is a kind of confidence. I don’t know where your judgment comes from. You actually have such an idea. Please, which of Xiao Yi’s achievements in mathematics can be compared with physics? 】

【The NS equation problem and the mass gap problem are the seven major mathematical problems of the millennium. "Mathematical" problems are all mathematical problems. Does that mean that physics is also a part of mathematics? I think physics students have a sense of humor. 】

【I think you math students are the real humor. You don't even look at Xiao Yi's recent achievements and see which ones are related to mathematics. 】

【Physics students are embarrassing themselves here again. Even if you say that the NS equation is related to physics, what do you say about the explosion tendency theory? This thing has nothing to do with your physics. It is a pure mathematical theory. 】

【Funny mud pee】

【Look, you are anxious again. You are broken.】

【You # ￥! x-on:……】

【……】

A war of words about whether Xiao Yi is a physicist or a mathematician was set off, which made people laugh and cry.

But given the mutual contempt between mathematics and physics, it is quite normal for such a thing to happen. After all, each wants to prove that the other is not as good as themselves.

However, such things only happen on the Internet.

Xiao Yi didn't pay any attention to this matter.

At this time, he received an invitation call.

"Hello, Professor Xiao Yi, I am Tim Bonas, President of the American Mathematical Society. First of all, on behalf of the American Mathematical Society, I would like to express my sincerest congratulations to you."

"The NS equation has a very important position in both mathematics and physics. We all know that it is closely related to the simulation analysis of fluid mechanics. Therefore, being able to solve this problem is a goal that all of us dream of, and you have successfully achieved this goal for us."

"Now, both the mathematical and physical communities are talking about you."

Xiao Yi in the office, holding the phone, listened to the other party's congratulations, smiled and said: "Thank you, President Bonas, solving such a problem is the wish of each of us, I am just lucky and found a way to success."

"Hahaha!" Tim Bonas laughed and joked: "If someone says that they are lucky enough to solve such a problem, then I am definitely willing to believe it, but If it's you, forget it. Someone who can solve two millennium problems may be lucky. You probably don't even believe this. "

Xiao Yi chuckled and didn't refute it. Then he asked: "But President Bonas called me for something else, right?"

Tim Bonas smiled and said, "Of course, there are less than ten days left before the end of the month's Joint Mathematics Conference. We have invited Professor Xiao to attend before, but you refused. But now, you have proved such a heavyweight problem. I believe that all the people who are going to attend the Joint Mathematics Conference are discussing this matter enthusiastically and are looking forward to hearing your report. "

"So, on behalf of this Joint Mathematics Conference, I would like to invite you again to come here to give a report on the NS equation. "

"Believe me, each of us misses you standing on the podium very much."

Faced with Bonas' invitation, Xiao Yi fell silent.

He had expected the invitation before he answered the phone.

The Joint Mathematical Conference is the second largest academic conference in the mathematics community after the International Congress of Mathematicians. There are more than a thousand participants each time, which can be said to be quite large.

It is indeed suitable as an academic conference for the report meeting on the proof of the NS equation problem.

But...

Xiao Yi said apologetically: "I'm sorry, President Bonas, it may not be convenient for me to go abroad now, so it may be difficult for me to go to the United States."

"In addition, I have other more important things recently, so I can't go to San Francisco to attend this year's meeting."

"In this way, there is no need to trouble the Joint Mathematics Conference because I temporarily adjusted the agenda."

"I plan to hold a report on the NS equation in March this year. The venue will be at the school where I work now, the University of Science and Technology of China. If President Bonas is interested at that time, I also welcome you to participate."

Hearing Xiao Yi's refusal, Bonas could only say helplessly: "Okay, I understand your choice. Of course, I will not refuse your invitation. I will come to China on time. After all, I am also studying PDE. I am probably one of the people who are most looking forward to your report."

Xiao Yi smiled and said: "Thank you for your understanding, President Bonas. I will welcome you in China at that time."

"Okay!"

Hang up the phone.

Xiao Yi shrugged and put the phone aside.

It is indeed inconvenient for him to go abroad now. As an outstanding young scholar and Yangtze River scholar, he needs to report his trip abroad, and then the Ministry of Foreign Affairs, National Security and other relevant departments will assess the risks and decide whether it is necessary to go abroad.

If it is a scientist in some social sciences or some completely civilian technology fields, it is naturally completely irrelevant whether he can go abroad or not. However, for a scientist like him who has mastered multiple core technologies and has unlimited potential, it is naturally not so easy to go abroad.

However, he doesn't care about this at all. Anyway, he is too lazy to go abroad. Isn't it better to stay in China?

He stopped thinking about these questions in his mind.

His thoughts shifted back to the problem he had been thinking about.

Greenwald limit.

Others thought that he developed the explosion trend theory in order to prove the problem of NS equation.

This is indeed true, but it is not so specific, because he proved the problem of NS equation in order to solve the problem of Greenwald limit.

Has the Greenwald limit really reached its limit?

Xiao Yi turned over the previous draft paper and found the new model he derived in order to combine the multi-fluid model and NS equation.

At that time, the model could not be advanced further because of the singularity problem caused by the NS equation. Only by proving the smoothness of the NS equation could it be advanced.

Now, he not only proved the existence and smoothness of the NS equation, but also proved it from a more general perspective.

Therefore, this old model can be completely rebuilt.

Combining the more generalized NS equation with the multi-fluid model to create a more complete model may allow the Greenwald limit to be pushed forward further.

Without any nonsense, he started to work.

Before, he used the NS equation with specific initial conditions to combine with the multi-fluid model. In this case, the technical requirements are relatively complex. After all, it is necessary to take care of various factors brought by specific initial conditions, and it is necessary to keep the original information when combining the two.

Now, under generalized conditions, it is much more convenient and faster to combine them.

Moreover, the new model he plans to build now is created on the basis of Xiao space.

Xiao space is very suitable for the construction of this fluid model.

Whether it is a low-temperature fluid or a high-temperature fluid such as plasma, it is the same.

Just like that, as time passed, Xiao Yi finally stopped writing.

Looking at the new model on the draft paper, he smiled and got it done.

Next, it was time to use the computer for calculation.

This kind of fluid model, of course, needs to be simulated by a computer, otherwise the direct numerical simulation DNS technology would not have been developed.

Calling Wang Hao, Xiao Yi ordered: "Please contact Chaohu Mingyue for me, I need to use the supercomputer."

Wang Hao nodded and said: "Okay, I'll call Director Tu of Chaohu Mingyue now."

Then he took out his mobile phone and left the office to make a call.

While waiting for the result of his call, Xiao Yi picked up the teacup next to him, took a sip, and then shook the cup.

Suddenly, his eyes stared into the cup.

At the same time, the ability of [Perfect Engineering] was quietly activated.

The field of vision suddenly changed.

Just like the need to measure the various data of the material through various experiments to activate [Material Mastery], there are also conditions to activate [Perfect Engineering].

That is, he needs to understand the complete structure of an engineering creation.

For example, for a mobile phone, he needs to understand the structure, location, wiring layout and other information of all the electronic components inside the mobile phone before he can start [Perfect Engineering] to simulate the mobile phone.

However, compared with the need for physical objects to master materials, [Perfect Engineering] does not need it. You only need to understand the structure in your mind to start simulation.

Of course, in addition to this, as long as Xiao Yi reads it carefully, [Perfect Engineering] can also be modeled directly in his mind and simulate the model of the entire engineering creation.
