God's Crown

"Don't worry." Professor Li Bo said with a smile, "You are such a big professor of mathematics and physics, this problem should not trouble you."

An Yan smiled dryly, but didn't know what to say.It seems that it's not good to say anything now, forget it or don't say anything.After thinking about it, he shook his head and looked at Professor Li Bo who was writing something on the blackboard with a pen.After a while, Professor Li Bo put down the pen in his hand and said, "No, this is the vector field."

"Let me try." An Yan nodded slightly.

Putting down the chalk in his hand, he clapped his hands, and Professor Li Bo said, "Since Professor An already knows, I'll go first. I still have some things to do. If Professor An needs anything, feel free to let me know." Call up."

"OK!" An Yan responded, and then he held a pen, folded his hands in front of his chest, and stood on the stage looking at the formula on the blackboard.Wang Yunqi below was not idle either, and was also silently calculating while staring at the formula.

Suppose M is a differentiable manifold, and a tangent vector is placed at each point of M. When the base points of these tangent vectors are required to move continuously, they also change continuously.Wang Yunqi recalled the basic content of the tangent vector field, let M be the Banach differential manifold...Wang Yunqi frowned while writing.

And An Yan didn't seem to have any intention of writing on the blackboard. Both of them were doing their own things, so naturally they didn't know what the other was doing.

Differential manifolds are actually not particularly difficult for An Yan.Before studying Abelian clusters, he studied differential manifolds or the entire topology in depth.He is now looking at the content on the blackboard and frowning. It's not that he can't do the content on the blackboard, but he is thinking about how to do the formula on the blackboard.

There didn't seem to be anything unusual about this formula, An Yan worked on it for a while.

Holding the pen in his hand, he also started writing on the blackboard.The movement is very fast. Originally, this formula is not particularly difficult, but the calculation is a bit complicated. As a physics professor, Professor Li Bo should be able to calculate it.Probably because the calculation time is too long, and he has other things to do, so this matter is handed over to him.

After a while, the whole blackboard was almost finished.

An Yan turned her head and looked at Wang Yunqi.

At this time, Wang Yunqi seemed to be a little confused from the look on his face. He didn't know what to do with the matter in front of him, as if... After calculating, he found something was not quite right.I didn't figure it out, so I put down the pen in my hand, "What?" An Yan said with a smile, "Didn't figure it out?"

"Probably." Wang Yunqi nodded lightly, "Professor, I'm still a little unclear."

"This topic is not particularly difficult, but it is a bit troublesome to calculate. These are minor problems. If you are not careful, you may make a wrong calculation or something. Look at your calculation results again. Is it because of the calculation that you can't do it?" Figure it out." After An Yan finished speaking, Wang Yunqi really began to look at his draft paper honestly.

Originally, according to An Yan's speed, the calculation could be completed today.If it wasn't because Wang Yunqi was his student now, and Wang Yunqi had to be given some time to think, maybe he would be able to fully calculate this problem in a few hours.

According to the current progress, An Yan estimates that Wang Yunqi should be able to fully calculate it the day after tomorrow, that is, Wang Yunqi can give the result to Professor Li Bo the day after tomorrow.An Yan said with a smile, "Let's do this, because the calculation of this project is a bit complicated, you should check it carefully, and you can do the project."

"Me?" Wang Yunqi was stunned, pointing at himself and said, "But the professor..." He wanted to say that he was still a college student, what should he do if he made a mistake in the face of this problem.

An Yan said one step faster than him, "This question, don't be afraid of doing it wrong, and don't be afraid of not doing it well."

"..."

"I also came here from you. I have already started to do graphene experiments at your stage. Don't forget, that is applied physics, which is a little more painful than theoretical physics."

Pursing her lips, Wang Yunqi took a deep breath and thought about it, then nodded heavily and said, "Professor, I understand, I will solve this problem properly."

"Just understand." An Yan wanted to give Wang Yunqi a chance to grow up. In the future, even without his relationship, Wang Yunqi would be able to quickly grow up in the country.He felt that he had always been quite accurate in judging people, especially when Wang Yunqi said that he didn't want to go back to China.But after graduating with a Ph.D., I am afraid that I will still return to China.

It is also helpful for him to meet some top domestic leaders now.

And An Yan himself is very optimistic about Wang Yunqi, such a genius is rare.It was as if Faltings took Pete Schulz very seriously.A genius like this is actually very important in the heart of the professor.In particular, An Yan will choose theoretical physics in the future. At least in the last few years or even ten years, he will develop towards theoretical physics.Mathematics is a very important tool. Without mathematics, the subject of theoretical physics would not have appeared.In other words, those physical theories can only survive in the world on the basis of ethereal things, and it is impossible to verify them at all.

Just as M theory has approached the limit of physics, it is something that cannot be verified.

Although quantum mechanics and high-energy physics still refer to M-theory to some extent, it is only to the point.There aren't many real references to M-theory.

An Yan, on the other hand, believes that Wang Yunqi can quickly master the knowledge of theoretical physics, especially the mathematical model, on the basis of a certain mathematical foundation.Maybe it's the next Edward Witten?As far as theoretical physics is concerned, there are many objects of worship of An Yan, such as Mr. Yang, Mr. Li Zhengdao and Edward Witten.

These are very great theoretical physicists.

As a person who pursues theoretical physics, there is only one goal that he wants to accomplish throughout his life-the grand unified theory of "the principle of everything".

Now there is only the unified theory of weak electricity, that is, the unified theory of weak interaction force and electromagnetic force.However, the theory of mutual unification of strong electricity, that is, the unified theory of strong interaction force and electromagnetic force, and the mutual unified theory of gravitational electromagnetic force, that is, the unified theory of universal gravitation and electromagnetic force, has not yet appeared.This leaves a lot of room for imagination for modern theoretical physicists.

He thought, I hope Wang Yunqi is the one who has the hope to make the truth of all things.

Of course, this is just his hope.As for what Wang Yunqi will grow into in the future, no one knows.

An Yan didn't dare to be sure what Wang Yunqi would be like in the future, he could only train him from this aspect now.Wang Yunqi himself is a genius, I believe these things are not too difficult for him.Hmm... As for himself, he can do whatever he thinks he can.

People always have a little dream, what if he really made a grand unified theory?

Seeing Wang Yunqi who was calculating, An Yan decided to go for a walk.

"Wang Yunqi, I'll go out for a walk first, I won't go too far, you do your calculations first."

Wang Yunqi didn't answer him, An Yan was used to it.Speaking of which, he liked it when he did it before.It's not that he didn't answer, but that he was immersed in his own world, and he didn't even think that he had to answer.So he went out by himself. The International Mathematics Research Center of Peking University is quite big. After wandering around for a long time, An Yan came to the lobby.

Someone was smiling at him, and after taking a look, that person seemed to be quite young.

Are you a researcher here?An Yan frowned and was thinking about it, when the man came over and said, "Professor An, hello."

"Hello." An Yan shook hands with that person, who are you?He looked at the person in front of him.

He looks very Zhou Zheng, with a bit of heroism between his brows, even wearing clothes that are quite old-fashioned throughout his life, it can be seen that this person is a very temperamental person.

"My name is Chen Ming." Chen Ming said, "I am currently an assistant researcher at the International Mathematics Center of Peking University."

"Oh?" He is an assistant researcher at a young age, but he is already very powerful.

"Doing geometry and topology." Chen Ming added, "Professor An, are you not at Princeton University at this time?"

"You...how do you all know that I'm at Princeton University?" An Yan said dumbfoundedly, "I really don't understand, I'm like a star, and you all know that I'm a professor at Princeton University."

"Actually, there are not many people in the domestic academic circles who know about your affairs." Chen Ming said with a smile, "Don't put on a bitter face, in fact, knowing this matter is very beneficial to your academic reputation in China. "

"Are you doing geometric topology?" An Yan said thoughtfully, "Which professor did you study at?"

"Look, my professor is here." An Yan turned around and saw a professor he had met at Princeton University nodding slightly at him, "Hi Professor An, when you were giving an academic report at Princeton University Wanted to visit, but when I went to the hotel, the waiter told me you had left."

"It's regrettable." The professor said with a smile, "My surname is Zhu, Zhu Zhenghe."

"Professor Zhu, I've heard of you. You are very good at geometry and topology." After An Yan shook hands with Zhu Zhenghe, "Are you planning to go back?"

"Aren't I afraid that Professor An will poach me?" Professor Zhu Zhenghe said half-jokingly, "You are the most legendary professor at Princeton University now, besides, who would want to go to the graduate student of our International Mathematics Research Center? Princeton University."

An Yan coughed lightly, "How could that be, Professor Zhu, you're overthinking, so I'll take a tour."

"But to be honest, Chen Ming is the best student I have ever seen. Since I met Professor An, I must give you a good recommendation of Chen Ming beside me."

"He not only has research in basic mathematics, but also in partial differential equations." Professor Zhu Zhenghe is a man in his 40s who looks like he is about 50 years old, and he speaks very gently.While chatting with An Yan, he recommended Chen Ming.

"That's right." Zhu Zhenghe said as if thinking of something, "Chen Ming has already graduated this year, isn't this the submission of materials to Princeton University?"

Chen Ming said with a hint of embarrassment, "I sent it to Professor An's mailbox."

"..." An Yan also started to feel a little embarrassed, he knew that there seemed to be quite a few doctoral students who applied for him this year.But it's very likely that you can meet them just by walking around the International Mathematical Center.

"I haven't started checking my mailbox yet. I'll check it when I go back." After talking with Professor Zhu Zhenghe for a while, An Yan left in despair.

At this time, Zhu Zhenghe said to Chen Ming, "I don't think this Professor An is very interested in you. Why don't you change to another professor? Shall I write you a letter to Professor Zhang Shouwu?"

"Professor, I'm going to try." Chen Ming pursed his lips and thought for a while. Anyway, he had already sent his information, and it was not too late.What's more, he has already been admitted by Princeton University, but when choosing a professor, he chose An Yan.If An Yan doesn't work, choose another professor.

In fact, Zhu Zhenghe expressed his understanding of Chen Ming's choice.

It wasn't that Chen Ming thought An Yan was good, but that he thought so too.Think about it in your own shoes, if you are only in your twenties like Chen Ming, Princeton University has such a great professor.And he was a 21-year-old Chinese professor. Thinking about it, his first choice would be this 21-year-old Chinese professor anyway.Moreover, this professor was a professor who graduated from a Ph.D. and became a professor in less than a year when he was studying for a doctorate, and he solved one of the problems of the Millennium Prize.

Think about it, how knowledgeable such a professor can be?

How could it be possible not to choose him, but to choose someone else?However, just thinking about the fact that this guy will go to the Yau Shing Tung Mathematics Research Center next door to receive the Morningside Mathematics Award this year makes people feel a little uncomfortable.But he is not a student of Peking University, and what is related to Peking University is the Department of Physics, which has nothing to do with the Department of Mathematics.

In fact, they don't have many connections in domestic academic circles.Why not be able to receive the Morningside Mathematics Award, what's more, even if you receive the Morningside Mathematics Award, so what?It is not to say that a medal can turn a top mathematician into an elite person.

What's more, An Yan will go to receive the Chern Mathematics Award in the second half of this year.

Maybe there will be a Fields Award next year, so why must this person be from Jinghua University?This is very unrealistic.Zhu Zhenghe said with a smile, "I also came from your age, so I know what you are thinking. Professor An is indeed a very powerful professor, but I heard that there are two Nobel Prize winners' recommendation letters from the University of Manchester." A student was rejected by Professor An."

Chen Ming was stunned for a moment, then took a breath and said, "No way, professor, can you be rejected with two letters of recommendation from Nobel Prize winners?"

"Yeah." Zhu Zhenghe didn't know where he heard the news, "I heard that Professor An recommended that person to go to his teacher."

"No, it can't be." Chen Ming felt that this was a very shocking news. Those who had two letters of recommendation from Nobel Prize winners were so disrespectful.Not to mention that it is impossible for him to get joint recommendation letters from two Nobel Prize winners.The one who can let An Yan save face is probably someone of Yang Lao's level.

Is this the legendary Princetonian arrogance?

Thinking about it, it's really scary.

"In short..." Professor Zhu Zhenghe patted Chen Ming on the shoulder and said, "Don't... think too much, kid. Be prepared. If it doesn't work, go to Professor Zhang Shouwu. Professor Zhang Shouwu and I still have some problems. If you are friendly, take your recommendation letter and see your grades, he should be able to accept you."

"Okay, I know the professor." Chen Ming took a deep breath.

Now no one knows what kind of style this doctoral student accepted by Professor An can only be prepared.If Professor An's side doesn't work, it's impossible for him to not have a professor at Princeton University.

Without a professor, it is too miserable to think about it.

After Professor Zhu Zhenghe left, Chen Ming followed Professor Zhu Zhenghe and left the International Mathematical Research Center.

Back in the research room, Wang Yunqi was still frowning and calculating.Even though it is summer now, the sun is almost setting.An Yan glanced at the time and said, "Wang Yunqi, don't forget, let's go eat first. After eating...you go back to the hotel and continue to count."

Wang Yunqi raised his head in confusion, looked at An Yan and said, "Professor, can you wait for a while? I'm about to finish the calculation here."

"That's fine." An Yan sat beside him and took out his computer.He thought that he happened to meet someone, so let's take a look at this Chen Ming's information.Sending his resume to him should have passed the test of Princeton University. When choosing a professor, he wanted to choose him.

After turning on the computer, connect to the Internet, and open your mailbox.Only then did he see that dozens of letters had been sent to his mailbox.An Yan pondered, is he really so famous?These emails were not sent to him by journals, nor were they sent to him by other professors he knew.It is estimated that all the people who sent him were those who wanted to apply for his doctoral students.

He originally accepted students in the first year, but he didn't want to accept too much.

But so many students who want to be his doctoral students - he really didn't expect it.After graduating from university in the United States, almost all of them study direct Ph.D.Of course, it doesn't rule out people like Chen Ming who want to study for a doctorate with him after finishing their graduate studies.

After looking through dozens of emails, An Yan finally found the email of Chen Ming.

Opening the email, he browsed slowly.

They all look pretty good, Chen Ming is a very outstanding student no matter in college or graduate school.In fact, An Yan was somewhat interested in such a student.

As for declining Han Qiu, it was really an accident.Obviously Han Qiu is studying applied physics, but he is studying theoretical physics.He couldn't mislead his son, so he directly rejected Han Qiu.Who knew that after this incident spread in Chinese academic circles, he became very critical of students.

If An Yan knew that he was being passed on like this, he would probably be extremely speechless.

After finding the contact information, An Yan took out his mobile phone and dialed the number.
