Yan Da.
As I have told Yanda before, the graduate student interviews will be held at Yanda.
There are many students who pass the written examination, but not many meet the requirements.
There are many students like Wei Dongyi and Xu Zhibin, so only five students can actually participate in the interview.
These five students are from Yanda University, Nankai University, Wudaokou University, and Tangdu Jiaotong University.
Wang Donglai didn't care so much. After an interview, he decided on two people directly.
One is Ding Hao, a student from Nankai, and the other is Zhang Zhi from Wudaokou.
In addition, Wei Dongyi, who came forward from Tian Gang to stay with Wang Donglai to study.
There are three people in total.
After the personnel are determined, things are very simple.
Follow the procedure directly and transfer the files of Ding Hao and Zhang Zhi to Tangdu Jiaotong University.
As for the two of them, they can choose to study with Wang Donglai at Yanda University, or they can choose to study at Tangdu Jiaotong University.
Because Wang Donglai had his own ideas about the arrangement between the two.
He has a lot of things to do, so it is naturally impossible to take two people with him all the time. What's more, at the postgraduate stage, he has to rely more on self-study, and the tutor can only play a guiding role.
Finally, there is another reason, that is, the reason why Wang Donglai chose the two of them was because their performance was pretty good.
Even without him, these two people can still achieve some results, provided they don't give up on mathematics and stick to it.
Inside the office.
There were three people standing in front of Wang Donglai’s desk.
Besides the slightly slovenly Wei Dongyi, there are two other people. One of them is a student who looks a little reserved with glasses, named Ding Hao. Next to him are the students who are taller and look quite confident. Zhang Zhi.
"Ding Hao, Zhang Zhi, you two are the graduate students I am leading this time, and Wei Dongyi is following you. Do you three have any ideas?"
"I will stay at Yanda for the next six months. I may not necessarily teach mathematics courses, but may also study physics."
"Ding Hao and Zhang Zhi, if they don't want to stay here, they can stay in Tangdu Jiaotong University, if you have any questions, you can send me an email and I will check it in two days. I will give you answers in due course. If you have any questions, you can go to the Institute of Advanced Mathematics and ask Professor Zhang and others for advice.”
“When you study under me, I will not force you to do anything, because I will. I believe that interest is the best teacher. As a subject of mathematics, if If you don’t focus on this and are unwilling to concentrate on research, you won’t be able to produce results.”
“My graduate students, Ding Hao, Zhang Zhi and Wei Dongyi, every time you are a graduate student. You have two thousand monthly living expenses, and I will personally subsidize it for you. The purpose is Let you focus on mathematics.”
“Each of you is good at it in different directions, but I hope you can spend more time in the library and study room. Mathematics depends on you. Talent also depends on hard work.”
"As long as you are willing to work hard, I, as a mentor, will try my best to help you!"
"How about, tell me what you think!"
Hearing what Wang Donglai said, Ding Hao Both Zhang Zhi and Wei Dongyi were a little surprised.
After all, it is rare for a tutor to give his students a living allowance of 2,000 yuan a month.
Secondly, there is the choice given by Wang Donglai.
Wei Dongyi naturally didn't have to choose. He was a student of Yan University and could only stay with Wang Donglai for half a year.
Ding Hao and Zhang Zhi glanced at each other, nodded to Wang Donglai, and said: "Teacher, we stay here."
Wang Donglai was not surprised. He made this choice. normal.
"Okay, since you stay here, you can study by yourself in the library and study room of Yanda during normal times. If you have any questions, you can come to me. If I am not in school , just send me an email, I will check it in two days, and I will reply to you when I see it.”
“As for student permissions at Yanda, accommodation, etc., someone will take care of it for you when the time comes. ”
This little thing can be done without mentioning Tian Gang's name.
“I understand, mentor!”
The two nodded in response.
"Teacher, what books should we read and what should we do next?"
Zhang Zhi, who was more confident, took the initiative to ask.
When Zhang Zhi asked about this, Wang Donglai smiled and said: "Well, do you still remember the written test questions I asked before? You should all recognize the last question."
"The three of you are in the third question The idea is quite good, that’s why I chose the three of you.”
“Let me give you a task. It’s September now, and before the end of the year, you three will first complete your postgraduate studies. After completing all the courses, this is not a problem for the three of you.”
“At the end of the year, I will check the learning status of you three.”
“ Wei Dongyi’s situation is a little different, so you can continue to improve your thinking on squaring a circle after finishing your studies. When the time comes, you can write a paper and ask me if you have any questions.”
"Of course, if you feel that this learning task is too simple, you can come to me at any time after completing it."
Wang Donglai's tone was very gentle, but he stopped at the words of Ding Hao, Zhang Zhi and Wei Dongyi In the ears, the faces of the three people suddenly fell.
The three of them had actually been mentally prepared before. Being Wang Donglai's graduate student would not be easy, and it would definitely be very demanding.
But when Wang Donglai actually arranged the study tasks, the three of them were still a little surprised.
It takes a few months to complete all the courses at the graduate level. Anyone who listens to it will think it is crazy.
Ding Hao and Zhang Zhi were able to pass the written examination and the interview, so they were naturally geniuses in mathematics.
Although the two of them had some confidence in themselves, they were also nervous.
But after hearing about Wang Donglai's arrangements for Wei Dongyi later, they immediately felt dissatisfied.
Why!
The two of them did not say this, but they held their breath in their hearts.
Wang Donglai has a clear understanding of the psychological changes between the two.
Actually, he did this intentionally.
Without competition, there is no pressure.
Let's just use Wei Dongyi as an irritant for the two of them, which will just stimulate the fighting spirit of the three of them.
In order to better achieve this purpose.
Ding Hao and Zhang Zhi's dormitories were also arranged next to Wei Dongyi's, allowing Wei Dongyi to help them settle in.
......
Wang Donglai did not deliberately hide the news about recruiting graduate students, so naturally it attracted the attention of university circles.
We did not recruit three graduate students, but only selected two, but we asked Wei Dongyi from Yanda University to follow him.
When this news spread, the mathematics departments of major universities immediately broke their teeth.
Especially Wudaokou next door, I regret it even more.
If I had known this was possible, they should have done it last year.
But I completely forgot that Wang Donglai taught classes for ‘Yao Class’ for half a semester.
The news that Wang Donglai was recruiting graduate students did not spread online. After all, the hot news on the Internet came one after another, and the entire society showed signs of high-spirited development.
The next time, Wang Donglai spent time in the library of Yanda.
Take Ding Hao, Zhang Zhi and Wei Dongyi with you.
Yanda’s library is larger in scale, has a richer collection of books, and has many cutting-edge technical papers and monographs. When Wang Donglai was in Wudaokou, he often spent time in the library. Now that he is at Yanda, he naturally does the same.
While reading, Wang Donglai was also thinking about the proof of the existence and smoothness of Navier-Stokes.
In my spare time, I give advice to Ding Hao, Zhang Zhi and Wei Dongyi.
It has to be said that these two are indeed students selected by Wang Donglai through large-scale screening. Their talents are definitely not as good as Wang Donglai's, but compared with other students, they are definitely outstanding.
Wang Donglai is confident that after his teaching, the three of them will become the mainstay of the domestic mathematics community.
It's a pity that Ding Hao and Zhang Zhi are the same age as Wang Donglai, and Zhang Zhi is even older than Wang Donglai. The two of them are bound to be under Wang Donglai's academic shadow throughout their lives.
With Wang Donglai's personal guidance, Ding Hao, Zhang Zhi and Wei Dongyi could be said to have spent sleepless nights in the library, devoting themselves wholeheartedly to mathematics.
Time flies and a week has passed.
...
“Huh!”
In the study room, Wang Donglai exhaled a long breath.
With bright eyes, he looked at the draft paper in front of him with a smile on his face.
“It seems that I have really chosen a big problem!!”
Wang Donglai murmured softly.
The more he studies the Navier-Stokes equations, the more Wang Donglai feels that there are endless mysteries in mathematics and physics.
What is the Navier-Stokes equation.
This equation was established by the Gallic scientist Navier and the British scientist Tox.
This equation is the correct equation used to describe turbulence.
And here, what is turbulence?
The famous Bald Eagle physicist and Nobel Prize winner Feynman once said: Turbulence is the last unsolved important problem in classical physics.
Heisenberg, the founder of quantum mechanics, a famous German physicist, and a Nobel Prize winner, once said this on his death bed: When I see God, I must ask him two questions. What is the theory of relativity and what is turbulence? I believe he only has the answer to the first question.
It can be seen that the difficulty of solving the turbulence problem is unimaginable.
After more than a hundred years of research, people believe that the Navier-Stokes equation is the correct equation to describe turbulence, and the results of the modern direct numerical simulation (DNS) of the Navier-Stokes equation are almost completely consistent with the experimental data.
From an engineering perspective, the Navier-Stokes equation describing turbulence meets application requirements.
However, mathematicians are more concerned about the existence and smoothness of the solution to the Navier-Stokes equation, and this issue has not been proven so far.
To this end, the Navier-Stokes equation is one of the seven Millennium Million Dollar Prize problems announced by the Bald Eagle Clay Mathematics Institute at the turn of the millennium.
The reason why Wang Donglai chose this difficult problem was actually that he didn’t think much about it. He just happened to think of it and chose this difficult problem.
As soon as I got started, I realized how difficult this problem was.
Of course, if this problem is solved, the rewards will be huge.
The most obvious application is that the design of aircraft can be greatly improved.
By then, whether it is military or civilian use, it will be a leap forward.
So after understanding this, Wang Donglai had already made a decision in his heart.
This conundrum can be proven, but not now.
With this decision, he did not use [Super Brain] and other abilities and skills to speed up.
Haste makes waste, and scientific and technological progress also requires a process.
At this time.
Wang Donglai’s phone vibrated.
Taking out the phone, it was Zhou Jun’s number.
After seeing this call, Wang Donglai remembered that he had informed Zhou Jun that he had developed a super battery.
Thinking of this, Wang Donglai's eyes suddenly became dark.
Because, he clearly contacted Zhou Jun a week ago, but it was only now that he got a call.
Thinking about it, Wang Donglai answered the phone.
After the simple communication, Wang Donglai’s expression became extremely calm.
soon.
Wang Donglai met Zhou Jun.
"Professor Wang, you really released a big satellite this time."
After meeting, Zhou Jun said to Wang Donglai with a wry smile.
“Director Zhou, what do you mean by this?”
Wang Donglai was a little confused and couldn't help asking.
"Professor Wang, are you feeling a little uncomfortable? The sample was obviously sent a week ago, but I didn't contact you until now?"
Zhou Jun did not answer directly. Instead, he changed the subject and asked other questions.
Wang Donglai nodded, shook his head, and said: "I'm not uncomfortable at all, I just feel that such a situation should not happen."
Wang Donglai's directness and lack of concealment, Zhou Jun His eyes lit up, and the smile on his face became more sincere, and he said: "Professor Wang, actually after you sent the sample, we conducted a performance test."
"The test results are extremely ideal and fully meet the requirements. I was planning to contact you after the test results came out, but at this time, something happened and the leader decided to postpone it."
"Professor Wang, You should be able to think of what happened, right?"
Hearing Zhou Jun say this, Wang Donglai quickly calculated the time and understood.
“I have a clear conscience!” Wang Donglai’s tone was calm, and his expression did not show any worry.
"Professor Wang misunderstood. The report you wrote actually caused quite a shock. Professor Wang must also know what kind of impact that report will have, and many people will have Dissatisfied.”
"At this time, the super battery happened to appear, so the leader reported it to the superiors."
"The superiors attached great importance to it, so the super battery sample was tested more rigorously, and the test results were also very Excellent, no, it cannot be described as excellent, excellence is more appropriate.”
“The super battery project is very good. important, so the leaders quickly reached a consensus."
"The super battery will be handed over to your company, and we will cooperate in accordance with the previous contract!"
"In addition, after the super battery, we will cooperate with you. With the success of the project, the leaders are ready to cooperate at more levels. I wonder what Professor Wang’s intention is?”
With a smile on his face, Zhou Jun gently asked Wang Donglai for his opinion.
Wang Donglai was very calm, not too proud, and said: "Director Zhou, this is just a semi-solid battery. I believe there must be laboratories in China that have batteries with better performance, and the cost may be high. Some, but if you are using it, you probably won’t care about the cost.”
Director Zhou smiled. He made a sound and said: "Professor Wang, there is indeed one, but the situation here is more complicated, and I can't say more."
"For the super battery project, the sample provided by Professor Wang is indeed the most suitable. That’s why I’m here.”
“Does Professor Wang have any ideas about cooperation?”
Wang Donglai nodded noncommittally, pondered for a moment, and then said: "Since you have taken a fancy to me, I have no problem, but what is the method of cooperation?" (End of Chapter)
