From University Lecturer to Chief Academician

That night, the official website of the Mathematical Society also issued an announcement, announcing a series of winners.

Some interviewing reporters at the scene released the news early.

Many media have started reporting.

Among the three major awards of the domestic mathematics society, the Hua Luogeng Mathematics Award is the most important, but because the winners are all mathematics academicians and top professors, they do not receive much attention, and there is nothing special to discuss.

The winners of the Zhong Jiaqing Mathematics Award are all doctoral students, and it is difficult for general doctoral thesis-level achievements to attract attention.

The most noteworthy thing is that Wang Hao won the Chern Mathematics Prize.

The day before the meeting, Wang Hao's latest research on "Approximate Solution of NS Equation" has been on the hot search of public opinion, which has aroused many people's discussions.

Now he has further won the Chern Mathematics Award, which is also the recognition of his work and research achievements in mathematics.

Many people discussed, "Wang Hao is really amazing, he set the record for the youngest age of the Chern Mathematics Award!"

"26 years old, Chern Shiingshen, I guess Fields will be in his thirties."

"Wang Hao's achievements are enough for Chen Shiingshen, it would be strange if Wang Hao is not judged!"

"I don't accept other people's awards, but I obey Wang Hao!"

"At the same time, there is also Zhong Mingchu who won the award, but I have never heard of it."

At the same time, some top mathematicians were also interviewed by reporters regarding the awards.

The vast majority of mathematicians are not well-known, even if it is a top mathematics professor in a university, it is difficult for many people to know his name.

However, some top mathematicians are different.

For example, Qiu Chengwen.

Qiu Chengwen can be said to be one of the most famous mathematicians in the domestic mathematics circle, and he is also very influential in the domestic mathematics circle.

When Qiu Chengwen was interviewed, he talked about his participation in the Mathematical Society, "I didn't attend the last and last conference, because I mainly focused on education and training young talents."

"But this time it's different. I'm here for Wang Hao's research."

"Of course it doesn't mean the study of that equation, but a mathematical method that he studied to change the column form from infinite to finite."

"This method, I think, has reached the Fields level. His report has attracted the attention of the international mathematics community, and it has been confirmed that it will be published in the "Journal of Mathematics" under the Institute of Mathematics of the Academy of Sciences."

"The reason why I say it has reached the Fields level is because this mathematical method can greatly advance the research on number theory and algebraic geometry, and can bring new ideas and methods to many researches."

"Here, I dare say that the next Fields will definitely have a Chinese name."

Needless to say, the Chinese name must be Wang Hao.

Qiu Chengwen's affirmation caused another round of heated discussions in public opinion.

There has never been a Fields winner in China, and the Fields Medal has only been awarded to two Chinese until now, one is Qiu Chengwen and the other is Tao Terence.

Qiu Chengwen was an American citizen when he won the award.

Terence Tao is an Australian citizen.

They can only be said to be Chinese, not Chinese, and they have received foreign education since childhood.

There is great hope in China that there will be a real Fields winner.

Now that Qiu Chengwen has affirmed it, and it is said that the next Fields may have Wang Hao's name, many people are looking forward to it even more.

Public opinion was full of Wang Hao's reports that day.

Wang Hao was very low-key. He just rested in the hotel and went to the meeting normally the next morning. Because he didn’t need to make a report, he went to various halls to have a look, and heard something related to the research field and his own interests. Content.

He listened to the report for a whole day without making any comments, but just listened carefully.

A lot of research can also make him feel bright, and he feels that he will have some ideas in his own research.

This is reflected in the increase in inspiration value.

Both tasks have increased a little inspiration value. Although the value increase is not much, the knowledge and ideas that can be brought are still a lot of gains.

However, on the second day, there were significantly fewer people attending the meeting.

The team of the Institute of Mathematics of the Academy of Sciences, including many top mathematicians and scholars in universities, has left early.

The purpose of their coming was to listen to Wang Hao's report. Since the report was over, there was no need to stay.

The plane of Wang Hao and Luan Haiping was also on the morning of the third day of the meeting, and they were not going to attend the rest of the meeting.

When the time entered the third day, there were only some small reports and some work meeting reports left.

On the fourth day, it has nothing to do with most other scholars. The Mathematical Society will hold enlarged meetings, board meetings, secretarial meetings, organizational work meetings, and so on.

To put it simply, it is to adjust personnel and work internally.

Wang Hao and Luan Haiping flew back to Xihai City together.

After getting off the plane, Wang Hao went back to put his luggage and items, and then went to the office of the complex building, busy preparing the lesson plans for the evening class.

at the same time.

Luan Haiping also went to the laboratory building of the Faculty of Science.

When passing by the teacher's office, Luan Haiping went in and walked around, and several professors looked over immediately.

Zhou Qingyuan immediately asked, "How is it this time? I saw the news. Wang Hao won the Chern Shiingshen Mathematics Award!"

"The school hasn't issued an announcement yet. Director Yang of the Propaganda Office just said that when you come back, it seems that you want to talk about the announcement."

Luan Haiping nodded and said that he would go and have a look in a while.

Then several professors talked about Wang Hao again, "Is there a lot of people in this meeting of the Mathematics Society? Dean Luan, you didn't introduce some top scholars. Let Wang Hao get to know him? He is still young, so he needs to know more about mathematics circles." There's no harm in anyone."

"Now he has won the Chern Mathematics Award, and he is considered to be the top in the mathematics circle, much better than us."

"Knowing more people who are good in the mathematics circle will be helpful in the future."

"Dean Luan, you still need to go out and take care of him on such an occasion. Wang Hao is too young after all."

Several mathematics professors are very concerned about Wang Hao.

They wanted to come to Luan Haiping and Wang Hao to attend the mathematics conference together. It must be Luan Haiping who took care of Wang Hao, because Luan Haiping would attend every conference. It can be said that he has rich experience and knows many people.

Luan Haiping grinned, but couldn't say a word. When he recalled the process of attending the meeting with Wang Hao, he felt that he was completely a foil.

Take care of Wang Hao?

What an international joke!

Every time he walks with Wang Hao, he is always the one ignored.

Others came to shake hands with Wang Hao, and completely left him aside. After experiencing it several times, he simply didn't want to be with Wang Hao.

That's how someone finally recognized him.

Is this him taking Wang Hao to the meeting? This is Wang Hao taking him to the meeting!

After greeting others, Wang Hao also helped introduce Luan Haiping. That scene was as embarrassing as it could be.

"Oh~~~"

In the end, Luan Haiping sighed and said, "In the future, there will be a meeting like this, so let's go, I will give you the seats."

"This kind of communication opportunity is more suitable for you to go."

"I'm old, I can't do it anymore..."

...

Wang Hao was busy sorting out the lesson plans in the office of the complex building.

In the evening it was "Fundamentals of Theoretical Physics". The reason why he rushed back was to not miss the course.

The study of NS equation is very important, and the study of annihilation force is equally important.

Moreover, he feels that he has made very fast progress in the research of physics. Every time he reads "Fundamentals of Theoretical Physics", he feels that he has gained a lot from the basic content.

The same goes for the lessons of the day.

In the time of one class, the task gained two points of inspiration, and I felt that I had new gains and ideas for the micro-mathematical system.

In the morning of the next day, Wang Hao went to the teaching and research office to sort out his new achievements in the NS equation.

"Boom boom boom."

There was a knock on the office door.

"Please come in!" Wang Hao shouted and raised his head, and saw Luan Haiping walking in with a middle-aged man.

"Don't bother me?" Luan Haiping said politely, walked in and let the middle-aged man sit down, and then introduced, "This is Professor Cui Xunnian."

He then gave a brief introduction.

Cui Xunnian's title is 'Professor', and he is actually a researcher of aero-ground dynamics. He has been engaged in the research of low-altitude aircraft flight in a certain equipment base for a long time.

Wang Hao was immediately in awe after hearing this.

There are many domestic experts engaged in research on military equipment.

People engaged in similar research will hardly appear in the public eye. Even if there are many major achievements, they will not be reported. It can be said that they are doing scientific research in obscurity.

Cui Xunnian is one of them. The research on the dynamics of aircraft flying at low altitude is obviously directly related to fighter jets.

Wang Hao quickly stood up and shook hands with Cui Xunnian.

Cui Xunnian looked very serious. Seeing Wang Hao smiling, he didn't have the philistine feeling of ordinary people, and he had a military-like temperament all over his body.

After he shook hands with Wang Hao, he directly explained the purpose of his visit, "We have recently encountered a problem in research, and we have consulted many other experts, but there is no way to solve it."

Cui Xunnian did not go into details, but handed over a document, which listed a complex equation system, "This is the equation system, we hope to find several sets of the most approximate solutions, but the results obtained by numerical substitution, During the experiment, it was found that it was not ideal.”

After listening to it, Wang Hao almost understood.

This involves the issue of aircraft design.

Aerodynamics is a branch of fluid mechanics, and aircraft design must involve the content of NS equations, and will adopt a design that minimizes wind resistance and increases engine air intake efficiency.

However, how to maximize this problem involves very complex calculations.

When encountering some difficult designs and higher performance requirements, it is necessary to obtain more accurate values.

This is a difficult question.

The solution of partial differential equations is originally a research direction, and most NS-related equations cannot be solved accurately by existing means.

If only an approximate solution is sought, the degree of approximation cannot be judged.

Cui Xunnian continued, "I read the latest report, Professor Wang, you have reached the highest international level in the research on approximate solutions of NS equations. I sincerely hope that you can help me solve this problem."

Wang Hao glanced at the equations and said, "I'm still doing related research recently, and I'll give it a try."

"Thank you, this is very important for our research."

Cui Xunnian said a few more words, and left with Luan Haiping.

After a while, Luan Haiping seemed to send Cui Xunnian away, and came back to explain, "Professor Cui came here suddenly, and I don't know the situation. Is the equation system very difficult? It's okay if they can't solve it. It is said that they found him Many mathematicians and experts in fluid mechanics have not solved it.”

He said and shook his head.

Wang Hao looked at the content on the paper and said, "I'm just giving it a try, and I can't guarantee it 100%. I'm currently researching this aspect, and it's good to have a look at it when I have time to learn about the application."

"It would be best not to delay your research." Luan Haiping was a little worried that Cui Xunnian's visit would affect Wang Hao's own research.

Wang Hao shook his head and said, "It's okay."

After Luan Haiping left, Wang Hao carefully looked at the content on the paper, which was a system of equations related to NS equations.

He carefully looked at the contents of the equation system, and suddenly froze.

He was thinking about a question before, because many NS equations may not have exact solutions, how to study approximate solutions that are infinitely close to exact solutions?

Now, the answer to this question came out.

equation set.

A single ns equation is indeed a problem of partial differential equations, but more complicated equations can be understood as equations of partial differential equations, and the difficulty naturally rises to a level.

A single partial differential equation may not be able to find an exact solution, and a system of partial differential equations may not have an exact solution.

However, there is a situation -

An infinite number of 'approximate ungroups' can be obtained, and it can be found among them that is closer to the 'ungroup' that makes the image of the original system of equations smooth.

This involves the content of algebraic geometry.

The ungrouping of the original equation system is not only a real number solution, but also an imaginary number solution. The image composed of the imaginary number solution will be very complicated, because the exact solution cannot be obtained, and the image of the ungrouping map is not clear, so it can only be substituted with approximate values. form to describe vaguely.

Then a certain "approximate ungrouping" can make the graph appear smoother, which is closer to the exact solution.

"This is too complicated!"

Wang Hao felt a headache when he thought about it, but he knew that his thinking was correct, so he began to study slowly.

...

The next day was another day of classes.

"Modern Partial Differential Equations" is a course that Wang Hao attaches great importance to, because the course may bring inspiration to the research of NS equations.

After finishing the explanation of a class, several students gathered around to ask questions, and Wang Hao answered them one by one, which took about half an hour.

By this time, it was almost over. Even if the students had more questions, he would not continue to answer them. After all, he was not a "answering machine" for the students, so half an hour more for answering questions was fine.

But there were still two students who stayed.

Wang Hao looked up and was a little surprised. It was his two graduate students in informatics.

Zhang Xinyi and Li Xin.

He asked strangely, "Why do you come to this class?"

"Modern Partial Differential Equations" is a very complex mathematics course. Functional analysis, even nonlinear functional analysis, is only the basis of the course, and graduate students of informatics are generally out of reach.

Li Xin shrugged his head and said, "Mr. Wang, we are here to ask questions. The information you gave us is completely incomprehensible to the two of us."

"Like..."

Zhang Xinyi immediately took out the information in his hand and put it on the podium, showed it to Wang Hao, and said, "This part of the content is the second page at the beginning. We thought about it for a long time, but we didn't understand it. "

"This computational transformation? Why?"

"From functions and collections, I suddenly jumped to this step, how did I derive it?"

Wang Hao glanced at it and knew what Zhang Xinyi was talking about. He explained, "This is very simple, it involves..." He immediately came to his senses, stopped talking and said, "I understand."

"ah?"

Zhang Xinyi and Li Xin looked up together.

Wang Hao said with a smile, "Are you trying to make yourself fat with one bite, so you just read this information thoroughly?"

"How is this possible?"

He walked out of the podium, took the stack of materials, and said, "The effective and irrelevant carry screening method is very difficult. If you want to understand all the content, you must first have a certain foundation."

"How about this."

Wang Hao thought for a while and said, "I recommend that you learn functional analysis and discrete mathematics by yourself. You should also grasp the content of probability theory."

"You can study these three courses while studying the content in the materials."

"Take your time, don't worry, in another three months, I'll check your progress."

"..."

"..."

Zhang Xinyi and Li Xin were dumbfounded. They are graduate students in informatics, and they have to study three difficult mathematics courses?

Wang Hao felt that the students still needed more comfort, and said with a smile, "This is the foundation, I have high expectations for you, come on!"

Zhang Xinyi and Li Xin looked at each other, and could only leave with bitterness. At first, they felt that it would be okay to spend more time just studying an algorithm data.

They are much better than graduate students in the Department of Mathematics, and they don't have to find the direction by themselves. Wang Hao has already explained the direction.

It turned out that what I thought was too simple!

Efficient vs. Don't Care Carry Screening?

This is a big pit, and after thinking about it, they will definitely not have any free time in the next three months.

Seeing the backs of the two leaving, Wang Hao had some expectations.

Of course, he doesn't expect much help from graduate students, but he still looks forward to the two graduate students in informatics.

As long as their foundations are kept up, they can still do some leftover work in programming and other fields.

There are also some programming problems that can be handed over to the students instead of wasting a lot of time for nothing.

...

In the next half a month, Wang Hao's life has been very ordinary, just accumulating inspiration points in class, and doing research patiently in the rest of the time.

He has made great progress in the approximate solution of the NS equation, and knows how to make transformations to make the approximate value more accurate.

The method is to compare the replacement equation with the original equation on the basis of the original results, and do more detailed analysis to continue to improve the replacement equation.

This step-by-step process can make the approximate solution closer to the exact solution.

For partial differential equations, it is relatively more complicated, but as long as it is transformed slowly, a more accurate approximate solution can still be obtained.

But occasionally I will encounter some problems, some can't figure it out, especially when studying the equations given by Cui Xunnian, every step of the change is very difficult.

Wang Hao has already obtained some results, but he feels that he can continue to refine them to make the values ​​obtained from the solutions more 'ideal'.

at the same time.

Cui Xunnian is also doing the same research.

The analytical problem of this system of equations has troubled him for a long time, and some of the solutions obtained after experiments have been found to be unsatisfactory.

He hopes to be able to get more precise unmarshalling.

After looking for Wang Hao, Cui Xunnian still had high expectations, but after three consecutive weeks passed, there seemed to be no reply from the other party, not even a single inquiry.

Cui Xunnian felt that it was not good to go directly to ask, so it was necessary to ask around.

He asked Peng Hui.

Peng Hui knew Cui Xunnian when he joined the army, and they have been in contact with each other intermittently.

Cui Xunnian knew that Wang Hao had participated in Peng Hui's project, so he called directly. The old friend called and exchanged pleasantries, and then turned to the topic, "You know Wang Hao, right?"

"I know Wang Hao very well." Peng Hui immediately said, "You know, Wang Hao, he is so genius!"

Cui Xunnian said, "I asked him a math question, but after 20 days, there was no reply, so I wanted to ask you to see what's going on?"

"Tell me?" Peng Hui asked with interest.

"It's just a complicated system of equations. No one in our research institute can solve it, and even others can't solve it." Cui Xunnian said, "So I looked for Wang Hao, but there was no news for a long time."

Peng Hui thought for a while and asked, "Is your equation system difficult?"

"certainly."

"The difficulty is so high, it should be very valuable to solve this problem?"

"Of course, this is directly related to design issues, and it is also very interesting for future research."

"Have you paid me? It's the project fee and labor fee."

"No?"

Peng Hui nodded and asked, "Then I understand."

"Ah?" Cui Xunnian was suddenly curious, "Why?"

"Isn't this obvious! Are you ashamed to ask?" Peng Hui asked in a loud voice, "Your research is so difficult and so valuable, but in the end you don't get any money, so you ask others to help you with the research, and I will give it to you." Graduate students are assigned work, and they have to pay labor fees. You can find an expert to help you, and you won’t take a dime out of it!"

"Mathematicians also have to live. Do you think it makes sense for people to spend so much energy on researching for you without paying any money?"

"Even if you are a military research institute, you can't do this!"

...

PS: I recommend the fire book "My Spy Years" by my friend "Zhutouqi", the first military book, more than 2 million words are enough, interested friends can go and read it.
