At two o'clock in the afternoon, the unfinished report of the morning will be carried out.

Compared with the morning, more scholars raised their hands to ask questions in the afternoon, and the questions raised were more application-level.

For these things, Xu Chuan is indeed a little powerless.

He can ensure the correctness of the theory, but he does not know how to apply the phased results of the NS equation to practical industry.

And there are some things that he can't answer at this report meeting.

For example, how to use the phased results of the NS equation to model turbulence, and even ultra-high temperature plasma turbulence, etc.

These things can only say that science has no borders, but scientists have borders.

Even if he knew how to use the results to model the ultra-high temperature plasma in the chamber of a controlled nuclear fusion reactor, he would not be able to say it here.

......

At four o'clock in the afternoon, after two hours of busyness, the report on the phased results of the NS equation finally came to a successful conclusion.

Judging from the repercussions of the meeting, the academic community has basically recognized his paper.

At least, there aren't too many doubts in the math community.

And the question of physics, to be honest, is not within the scope of Xu Chuan's answer.

The NS equation is indeed a top problem in the field of fluid mechanics, and can also be used to solve various turbulence problems, but fluid mechanics is more applied after all.

A symposium in the field of mathematics will never be able to reach into the application of physical mechanics.

Amid loud applause, Xu Chuan ended the report meeting, and then walked towards the exit of the auditorium.

It's time to go and get the news out to the world!

Walking out of the auditorium, he was surrounded by a crowd of people who had been waiting outside.

Among those who surrounded him were journalists, academics, and simply admirers of him.

Not everyone was able to squeeze into the auditorium for the presentation, and many people who arrived late or didn't receive the invitation were waiting outside for the results.

"Hello Professor Xu Chuan, I'm a reporter for the Los Angeles Times......."

"Professor Xu, how is the result of the report, can you tell me about the success? Is the ns equation solved? ”

"Kawajin! Can I shake your hand? ”

"Hello Professor Xu, I am a reporter from Jinling Daily, may I ask if your paper has successfully proved the ns equation?"

"Chuanshen, I'm a math student at Peking University, can I add authority or leave a phone number? I want to learn math from you! ”

“.......”

Outside the auditorium, Xu Chuan was blocked by the crowd as soon as he walked out.

All kinds of questions came flooding in, some from media reporters, and some from other onlookers.

After picking some media and answering questions, Xu Chuan was ready to let people go, but these enthusiastic onlookers obviously didn't intend to let him go so easily.

Fortunately, the staff in charge of reporting the order of the meeting at NTU discovered the situation here and quickly rushed over to relieve the siege and rescue him.

"Whew~"

After being pulled out of the crowd, Xu Chuan breathed a sigh of relief and walked towards his office.

Now there is no need to rush back, there is also a dinner and exchange meeting in the evening, just in time to exchange with other mathematicians.

Even he has to maintain his attention to mathematics and the absorption of knowledge.

After all, mathematics has always relied heavily on inspiration and communication, and working behind closed doors is not a discipline for this subject.

Smoothly returning to the office, Xu Chuan pushed open the door and walked in, leaning on the chair to rest.

I have to say that today's report will really be the most tiring in the history of his life.

The NS equation is so relevant that even if it is only a phased achievement, it still attracts the attention of many scholars in the two major fields of mathematics and physics.

The impact of fluid mechanics on society is simply too great.

Airplanes, missiles, rockets, automobiles, trains, bridges, high-rise buildings, and other structures are all inseparable from the design of fluid mechanics.

Hydrodynamics is also indispensable for dams, hydroelectric power, ship design, port and coastal engineering, underwater pipelines, sewage treatment and tap water supply.

Even in medicine, in the fields of hemodynamics, respiratory mechanics and digestive system mechanics, fluid mechanics can help humans better treat diseases.

In addition, there are various disciplines such as atmospheric science, environmental protection, and biological engineering, in which fluid mechanics plays a key role.

While he was resting, there was a sudden knock on the office door.

Coming back to his senses, Xu Chuan beckoned: "Please come in." ”

"Xu, congratulations, you have solved another difficult problem."

It was a middle-aged man who walked in, even though it was already early May, and he was still wearing a neat suit and tie.

After glancing at the visitor, Xu Chuan got up with a smile and greeted: "Editor-in-chief Camilo, hello." ”

He was well acquainted with the editor-in-chief of the Annals of Mathematics, Camilo de Lylis, a member of the Princeton System and, of course, an alumnus.

Camilo de Lylis stepped forward with a smile and gave Xu Chuan a warm hug.

"Long time no see, Xu, congratulations on solving another Seven Millennium Problem, it's really unexpected." Camilo smiled and congratulated.

"Thank you, but I haven't solved the NS equation yet, and it's only a phased achievement yet, and it hasn't been peer-reviewed yet." Xu Chuan replied with a smile.

"Wow, Xu, you're so humble. Today's presentation was wonderful. ”

Camilo shook his head exaggeratedly, and then smiled: "Xu, I think you should know why I came, leave it to me, the Annals of Mathematics promises not to live up to it, and we will treat it like our own son." ”

"To this end, we have invited Professor Tao Zhexuan, Professor Qiu Chengtong, Professor Smirnov and other experts as reviewers, and now only your paper is missing."

"It's too much of an exaggeration, it's all Fields Medal winners." Xu Chuan shook his head and smiled.

"No, no, no, it's worth it!" Editor-in-chief Camilo seriously retorted: "This is the seven millennial problems, even if it is only a phased achievement, it is worth facing with the most important attitude by everyone." ”

"And, I don't think there's any other journal worthy of it than the Annals of Mathematics!"

Xu Chuan smiled, skipped the topic and said, "I'm sure you guys will treat him well." ”

It is not a question of what to match or not, and the Annals of Mathematics is indeed the most famous of the four top journals at present.

Because it was founded by scholars of the Princeton School, and Princeton is currently the mecca of mathematics in the world, most of the results made by scholars who came out of here were voted to the Annals of Mathematics.

He also brushed a lot of papers in the Annals of Mathematics, whether it was the proof of the weyl_berry conjecture or the proof of the Hodge conjecture, all of which were submitted to the Annals of Mathematics.

The phased results of the NS equation this time, if there are no accidents, are estimated to be voted for the other party.

What's more, the editor-in-chief of Camilo also came over in person.

Hearing Xu Chuan's answer, the editor-in-chief of Camilo de Lylis turned happy and quickly said, "Of course! Once the peer review is complete, we will arrange for it to be published as soon as possible. ”

......

After being invited to contribute, Camilo de Lylis did not bother too much, and left after a short chat.

After Xu Chuan rested for a while, he also got up and went to the dinner restaurant.

The networking dinner after the presentation is an unmissable occasion for any mathematician.

Here, you can find any math guru you are interested in to say hello, exchange ideas, and ask questions..... There is almost no rejection.

After politely responding to the scholars who came up to greet him warmly, Xu Chuan also found his mentor at Princeton, Professor Deligne.

At this time, the old professor was holding a wine glass and communicating with Qiu Chengtong.

"Mentor, Professor Qiu." Xu Chuan smiled and stepped forward to say hello to the two.

"It's a wonderful proof, it seems that you haven't wasted your math when you return home." Deligne nodded, a rare compliment.

He was worried that the student would waste his talent in mathematics, but now it seems that he didn't.

On the side, Qiu Chengtong said with a smile: "It seems that the last exchange in Mizuki inspired you a lot, and I saw something quite familiar in your proof process." ”

Xu Chuan said with a smile: "I am very grateful to Mr. Qiu and that classmate for the inspiration they brought me. ”

Qiu Chengtong laughed and said: "You don't know, you mentioned in your paper, how happy my student was, and I didn't come today, if I came, I guess I would have to ask you for dozens of signatures." ”

On the side, Deligne asked, "What are you going to study next?" Listening to Feverman, you don't seem ready to go any further on the NS equation? ”

Xu Chuan nodded and said, "Yes, I also want to solve this problem, but my mathematical intuition tells me that to solve this problem is probably not what I can do now." ”

Deligne nodded, he knew the character of this student, and if there was really any hope of solving the NS equation, he would not let it go.

Skipping this, Xu Chuan opened his mouth and asked, "Mentor, is there any hope for the fact that I communicated with you before and borrowed Princeton's chemical experiment database?" ”

When he was researching artificial SEI films last year, he thought about making a chemical mathematical model to help him develop chemical materials.

This is a very ambitious plan, but of course, it is difficult to achieve. To this end, he contacted NTU and Mizuki University to join forces to try.

In addition, at the beginning of the year, he also approached Deligne, told him about it, and asked Deligne to help him communicate with the head of the chemistry department at Princeton University to see if he could borrow the database from Princeton.

Although Princeton's chemistry department is not as good as mathematics and physics, it has also produced several Nobel laureates in chemistry, and its strength is still quite strong.

Coupled with the accumulation of experiments over a long period of time, it would be very good if you could get the help of Princeton.

Of course, this probability is not very large.

On the one hand, he is not in Princeton, and on the other hand, it is difficult to achieve this kind of cross-border university cooperation, especially between China and Mimi, especially in the field of materials research and development.

But Xu Chuan always has to ask, what if there is hope?
