National Top Stream

"But." Director Zhou still didn't quite understand, "This is not an outsider, it's your grandson."

"What's wrong with my grandson." Principal Chen Zhong said seriously, "Longcheng University did make a lot of contributions in mathematics in the past few years, but now it's not good. What have you researched one by one? The students didn't take it well either?"

"Even if Rui Ning comes back, are you sure that our Department of Mathematics and Physics at Dragon City University will be able to stand up?" Principal Chen Zhong stood up, "The key is not to rest on the laurels of previous achievements. This Li Fei can come, It was Rui Ning who invited him here. If the academic atmosphere here is not good enough, can he not leave?"

"Rui Ning is here. The academic atmosphere of our Longcheng University is too bad. Do you think he will leave?" Principal Chen Zhong glared at Director Zhou, "So, it's hard to beat the iron."

"Principal, it's not that I don't work hard." Director Zhou rubbed his brows, "I also worked hard for our mathematics department."

"Think about it, we were comparable to the mathematics departments of Peking University and Jinghua University at the beginning, and it has fallen so much over the years. It's not that I don't want to keep it. But you know about the funding issue."

Principal Chen Zhong and Director Zhou sighed at the same time, now Longcheng University is in a dilemma.Their mathematics and theoretical physics can be said to be the most outstanding subjects, and countless students are willing to come to Yongsong University to study mathematics and theoretical physics.However, in recent years, Longcheng University's performance in mathematics and theoretical physics has been particularly poor, and it has been caught up by later schools. Let alone No.4, I am afraid that it will not even be able to keep the top ten.

It is difficult to find high-level professors, and their own research in this area, especially in pure mathematics and theoretical physics, is even worse than that of Beijing University and Jinghua.

The reason why Director Zhou is looking forward to Zhuang Weiran's return is also because Zhuang Weiran's arrival will form a siphon effect.As one of the top mathematicians in the world, Zhuang Weiran must be able to attract a large number of outstanding talents in mathematics to study at Dragon City University.

For example, in the Mathematical Olympiad competition, those who get national rankings are usually in Beijing University or Jinghua, and rarely choose other schools.The reputation has gone there, the top students in Huaguo have gathered, and the resources of teachers are getting better and better.Longcheng University, which used to be comparable to Peking University and Jinghua Department of Mathematics, is lonely.

But there is no way to do it. Mathematics requires a genius.And gifted students are either in Beijing University, Jinghua, or directly go to the youth class of China University of Science and Technology.What about Dragon City University?

"I'm wondering, can we also open a youth class?" Director Zhou cautiously asked, "I'm wondering why the University of Science and Technology of China is doing so well, and the youth class also has a lot of bonuses. Our Longcheng University is also the number one school in Longcheng Province, and it belongs to 985 and 211, so why can Huake University do it, but we can’t?"

"Okay, then what?" Chen Zhong looked at Director Zhou, "Think about it, the junior class is not the solution."

"The right way is to really cultivate students with academic accomplishment." Principal Chen Zhong rubbed his brows.

"In fact, we have trained a lot of students over the years, but unfortunately not many students are willing to stay in school. Especially after studying abroad, there are not many students who want to return to China. Of course, we can't force anyone Where should the students go?" Chen Zhong mused, "But we also have to find a way to keep the outstanding students in the school."

Director Zhou just sat on the chair, "Principal, let me tell you the truth, don't dislike it."

"If your grandson He Ruining comes to the school, I believe that many outstanding students are willing to stay in the school as teachers, or come back from abroad. You also know that talent is very important in the study of mathematics. We have seen Many talented students, but this is the first time I have seen someone like your grandson who can basically be called a modern-day Gaussian."

"If he comes to teach at Dragon City University, no matter whether he is looking for him to discuss academic issues, or students who want to worship under him, I'm afraid he will be ranked outside Dragon City from the Department of Mathematics." Director Zhou paused, " Of course I know that academics should not be superstitious about authority, and the development of the school depends on the joint efforts of all teachers and students. But sometimes, the benefits that a top master brings to the school are also obvious."

"I heard that he invested in the laboratory recently?" Chen Zhong took the notebook next to him and began to sort it out, "What's going on?"

"Graphene." Director Zhou shook his head, "Our school is actually not very good at being together. There are only two or three big cats and kittens in that laboratory, but he seems to be confident and wants to do things related to graphene. .”

"I remember that he didn't study this direction before?" Chen Zhong frowned very much, "This thing was created by Ruishi, and I wasn't particularly optimistic about it. Now the commercial technology of graphene at home and abroad is basically mature. , There is not much profit in entering this area. He is a mathematician, so it is impossible to think of it."

"I don't understand." Director Zhou really didn't understand Zhuang Weiran's operation, "Compared with this, principal, I think it is more important to notice that the lighthouse country has tightened the restrictions on international students, especially for Huaguo. Quota for international students. Many science and engineering majors almost do not accept overseas students from China. I think this is a signal that it is indeed easier for Ruining to communicate with mathematics problems there. Communicating with so many masters is better than the atmosphere in China. It's much better. But... you said, what if he doesn't come back?"

"You also came back from Princeton University, and you know how domineering the Beacon Country is."

"Yes." Chen Zhong nodded, he was fine at that time.It was much more relaxed than it is now. At that time, Huaguo hadn't developed yet, and it can be said that the Lighthouse Kingdom didn't care about Huaguo at all.These people returned to the country, and even the people there thought that they would come back again in a short time.

It is different now, no matter in terms of national development or research.It is true that there is still a big gap between Huaguo and Lighthouse Nation, but the treatment of top scholars is actually not much different.Especially for academic leaders like Zhuang Weiran, it might be better to be in Huaguo.

There are many masters in Lighthouse Country, but if Zhuang Weiran returns to Hua Country, then he will be the only math master in Hua Country.Undoubtedly, his academic status in Huaguo is very high.Even in the future, it will be the leader of Huaguo mathematics, the kind of existence that will make the Huaguo mathematics community tremble with a stomp.

In addition, in fact, their whole family hopes that Zhuang Weiran will return to China as soon as possible.

They can't stop Zhuang Weiran from being a visiting scholar abroad for academic purposes, they just hope that he can return to China as soon as possible.

"Principal, look, I still have some things to do here, so I'll go get busy first?"

"Okay, let's go." Principal Chen Zhong waved his hand, looking at Li Fei's resume, he was fascinated for a while.Director Zhou is right. Sometimes a well-known scholar can bring a lot of benefits to the school.But the reputation of well-known scholars is also temporary, and in the end it depends on the academic atmosphere of the school.

From the moment he returned to Dragon City University, it was as if he wanted to build Dragon City University into the mathematics center of China and even Asia.The academic atmosphere is a very important thing, but it is a pity that it has not been completed after all these years.

I just don't know if Rui Ning can fulfill his long-cherished wish after he comes back.He himself is not a student who graduated from Dragon City University, but Dragon City is his hometown, and the ancients said that fallen leaves return to their roots.Since he came back from the Lighthouse Country, he naturally returned to Dragon City.

In that era, it was pretty much the same everywhere.

After returning to Dragon City, after so many years, Dragon City University has indeed changed a bit, but unfortunately it is not enough.Now we have entered a predicament, or in other words, have entered a bottleneck.If someone can get Longcheng University out of this bottleneck at this time.Maybe Dragon City University really has the possibility to become the mathematics center of China and even Asia. Originally, Dragon City University has already had such a foundation in the past 30 to [-] years.Just one more chance.

Principal Chen Zhong stood up, looked out the window, and sighed softly.Director Zhou is waiting for Rui Ning to come back, what if Rui Ning goes to Capital University?That was his alma mater.At the beginning, he also almost went to Beijing University.If it wasn't because he still wanted to go back to his hometown, he wouldn't have come to Dragon City.

…………

"Zhuang, congratulations, you have become a chair professor of Princeton University." Handing the letter of appointment to Zhuang Weiran, Princeton University President Christopher Isgrubb smiled happily. After taking a group photo, Zhuang Weiran stepped off the stage.

The professors below all smiled and said to Zhuang Weiran, "Congratulations, Zhuang."

"Thank you all."

"Zhuang, will you come to the party tonight?"

"Of course." Zhuang Weiran smiled, "See you tonight, Professor Feffman."

When I came to the office, this office was just vacated and cleaned.But basically nothing was placed there. When Pierce came in, he looked a little pitiful when he saw the huge empty office.

He was very surprised, Professor Zhuang is a chair professor, why is the office...so simple?

"Professor Zhuang." Pierce looked at the office in front of him suspiciously.

Zhuang Weiran smiled, "Why, do you think there are too few things in the office?"

Pierce smiled and dared not speak, Zhuang Weiran pointed to the chair in front of him and said, "I have seen the recommendation letter from Professor Wiles. You have been at Princeton University for a while, right?"

"Yes." Pierce nodded. "It's been a long time."

"Mr. Pierce." Zhuang Weiran looked at him seriously, "I need to tell you something."

"Professor, tell me." Pierce listened carefully.

"Actually, I won't be able to stay at Princeton University for a long time. I am a native of Huaguo, and I applied for a visiting scholar to come to Princeton University. That is to say, I still have to go back to Huaguo, and, to return to Huaguo After that, I don’t plan to teach in other countries. I don’t know if you can understand me, but I need to explain to you that my time at Princeton University is only one or two years at most.” Zhuang Weiran said with a sigh , "Obviously, according to my standards, I don't think you can graduate within one or two years."

"I might be able to recommend Professor Deligne to you, or any other professor. Pierce, you are a very talented scholar, and I don't want to delay you. Do a project with me. After I leave, maybe your project It needs to be done again. It takes too much time."

"Professor." Pierce puffed up his chest and said to Zhuang Weiran, "I came to Princeton University to learn mathematics from you. Even if you return to Huaguo, if you want, you can give me a project to do. I I believe that no professor will deny the subject you gave me."

"But I'm not at Princeton University." Zhuang Weiran shook his head. Pierce's idea is very good, but the chance of realizing it is not very high.After all, after he returned to Dragon City, he had to take other doctoral students with him.He didn't even have time to deal with Pierce, plus jet lag.Almost impossible to explain to Pierce.

Pierce was indeed gifted in mathematics, otherwise he would not have become a student of Wiles.So Zhuang Weiran didn't want to delay Pierce, maybe because Pierce studied with him, Pierce's math talent was delayed, which is not a good thing.

"Mr. Pierce, I am very happy to accept yours." Zhuang Weiran raised his voice and said sincerely, "But you must know that I may leave Princeton University in a year or two. I am here as a visiting scholar. to Princeton. So I'm definitely not going to be here for many years."

"Sorry, I know you will definitely show your ambitions in mathematics, and I regret that I can't be your tutor." Zhuang Weiran sighed, "If you can, you can go to Mr. Deligne. During my period at Princeton University Time, if you don’t understand anything, you can ask me.”

Pierce's face was obviously not very good-looking, Zhuang Weiran looked at Pierce, "Or go to other professors? Do you have any professors you want to follow?"

"Professor Zhuang, I want to study mathematics with you." Pierce said very seriously, "I came to Princeton University from England, and I want to study mathematics with you."

"..." Zhuang Weiran had a headache. Obviously Pierce was determined to study mathematics with him, but he had already told Pierce that it was impossible for him to stay at Princeton University until he graduated with a Ph.D.

"Okay." Zhuang Weiran really had nothing to do with this stubborn Pierce, "You can convince me."

"From now on, you study mathematics with me." He paused and said sternly, "But, Pierce, I need to remind you that since you study mathematics with me, I will be very strict."

Pierce smiled slowly, "No problem, Professor Zhuang, I am happy to accept your severe criticism."

"First of all, I'm promoting the Abelian field. You can join this project, or should I draft a new topic for you? Or are you planning to draw up a topic yourself?"

"Professor, may I join your project on the Abelian field?"

"Yes." Zhuang Weiran nodded, and reminded Pierce, "The speed of the subject is very fast. If you can't keep up, I think you can change to a simpler subject. I gave you a lesson in the field of functional analysis before." The topic, you send it to me by email."

"Thank you, Professor." Pierce was ecstatic. Zhuang Weiran looked at his expression and continued, "Pierce, I will send you the progress of the current research by email. You'd better see if you are suitable, if not , I will propose another topic for you, of course, you can also find a new topic to do. Algebra, geometry, functional analysis, topology, partial differential, ordinary differential, etc., are all fine.”

"Knock knock knock" at this moment, the door was knocked.

"Come in." Lin Sen came in from the door, and he said with an embarrassed smile, "Professor Zhuang, Professor Wei Teng asked me to come to you."

"Oh?" Zhuang Weiran looked at Lin Sen, "What did Professor Wei Teng ask you to come to me?"

"He said that I need to follow you to learn some knowledge about the field of functional analysis and theoretical physics, especially gauge field theory." Lin Sen was very embarrassed. He was rushed to find Zhuang Weiran just after being accepted by Professor Weiteng today.He didn't know why, so he asked him to follow Zhuang Weiran to learn functional analysis and theoretical physics.

The corners of Zhuang Weiran's mouth turned up slightly, "I know what Professor Weiteng means."

"Sit down." Zhuang Weiran looked at Lin Sen, "I remember that you didn't do much research in the field of functional analysis before, and almost never did gauge field theory."

Pierce turned his head to look at Lin Sen, and smiled at him, "Lin, we meet again."

Now Pierce is very happy, so after seeing Lin Sen, he greeted him directly.Lin Sen, on the other hand, looked extremely cramped, and said with an embarrassed smile, "Mr. Pierce, we meet again."

"Okay, Pierce, if you have nothing to do, you can go back first. Remember to send me the email." Zhuang Weiran took the draft paper on the desktop and began to look.

"Professor Zhuang." Pierce stood up and saluted Zhuang Weiran like a gentleman, "I'm leaving first."

After Pierce left, Lin Sen was left cramped in the office.Zhuang Weiran didn't speak either. Lin Sen was suffocated by this weird atmosphere.

He looked at Zhuang Weiran cautiously, "Professor Zhuang?" In the office or in Princeton University, it is impossible for him to call Zhuang Weiran cousin.

If he hadn't been too excited before, he wouldn't have been able to call out.A professor is a professor, even his cousin is still a professor.What's more, he is a chair professor.

"Do you know why Professor Weiteng asked you to come to my place?" Zhuang Weiran casually looked at the draft paper, holding a pen and preparing to calculate.

Lin Sen shook his head, "I don't quite understand. I just went to Professor Witten's place today, and he asked me to come to you."

"You know that M-theory and loop quantum theory are the most likely to succeed in the Theory of Everything, right?" Zhuang Weiran kept writing on the draft paper without even looking at Lin Sen.

Lin Sen nodded slightly. He did hear Zhuang Weiran and Professor Weiteng discussing before, but there were still many things that he didn't understand at all.After that, I read a lot of documents and materials, but it was too difficult to understand their profound thoughts.He is still in a state of vague understanding.

"Professor Witten thinks that you are very talented in mathematical physics. I have a different view from Professor Witten." Zhuang Weiran paused, "I have read M theory and loop quantum theory. Both of these theories hold a skeptical attitude. This is why I debated with Professor Witten. He asked you to follow me to learn, just to learn something from me. Then follow him to learn, It’s just the saying that gathers the strengths of a hundred schools of thought.”

"got it?"

"Understood." Lin Sen nodded. It turned out that Professor Wei Teng meant that.Why didn't he think of it just now, probably because he was rushed to Zhuang Weiran's place when he went to Professor Weiteng's office on the first day, he was a little confused.

But hearing Zhuang Weiran's words, Lin Sen was in high spirits.

"So, doesn't Professor Weiteng dislike me?" Lin Sen scratched his head, thinking that Professor Weiteng disliked him, and accepted him because of Zhuang Weiran's affection.After accepting him, they sent him to Zhuang Weiran's side.Unexpectedly, it's not that I dislike him, but that I want him to learn more things.

"Otherwise, what do you think?" Zhuang Weiran smiled, "You don't think that Professor Weiteng doesn't want to see you, do you? If Professor Weiteng doesn't want to accept you, he will tell me directly, and he won't go around this big circle. Totally unnecessary."

"..." Lin Sen smiled awkwardly, but did not speak.

"Okay, if you're okay, go to the library to find some literature and materials on gauge field theory. I personally don't recommend you to read the gauge field theory I made before. You start with the simplest one, and Parity is not conserved, you need to do more research."

"Okay." Lin Sen stood up, "Then... I'll read the book first."

Lin Sen left, and the entire office was empty.Zhuang Weiran turned on the computer and emailed his current study to Pierce.

When Pierce received Zhuang Weiran's email, he was about to send him the content of the functional analysis he had done before.After clicking on the email, Pierce looked at it for a long time, and he was sure that he couldn't keep up with the professor's speed.The speed of the professor's research is too fast, he can't keep up with this rhythm at all.If he really had to do it, it would only be self-defeating, and even drag the professor down.

[Professor, after reading your current research progress, I can't keep up.Professor, you give me a topic, let me study it.I don't have a good subject right now, and I'm doing nothing. I hope you can give me a topic for me to study. 】

Zhuang Weiran smiled after receiving this email.It seems that Pierce really can't keep up with his progress. He expects to complete the promotion of Abel Domain before Christmas. BSD guessed that the rest of the work should be done before June next year. Zhuang Weiran didn't find it strange that Pierce couldn't keep up with his progress.

There are few people in this world who can keep up with his progress, there is no doubt about it.Zhuang Weiran never doubted his research ability.

He did find a problem in algebra and sent it to Peirce, homology algebra, a new branch of mathematics, an algebraic method formed with the development of topology, especially homology theory.It develops some problems in algebra that have been individually studied in the past, and uses a unified point of view to give a powerful development, forming a field as a general system.This method is based on the viewpoint of category and functor, and it is characterized by not only dealing with the internal structure of the object, but also dealing with the functional structure of the object.

Pierce was ecstatic when he received the project, but he didn't expect the professor to have researched in homology algebra.

And now Zhuang Weiran has left the office. He has no class today, and he doesn't need to talk about some topics to the students. He has already gone home early to study the unpublished research results of algebra and geometry that Grothendieck gave him.

His thoughts are so profound that even Zhuang Weiran can't fully understand them now.For many things, he needs repeated calculations to understand these ideas.This is still a relatively simple part, but Zhuang Weiran now finds it very difficult to even look at the most complicated part.Staring at these calculations, he needs to run his brain [-]% without any mistakes.

Studying mathematics is actually a very boring and no fun thing.At least for most people who are not interested in mathematics, studying mathematics is too boring.Research in any academic field is boring.Even literary studies are quite dull and obscure.

And like Zhuang Weiran is like now, after Grothendieck handed over these achievements to Zhuang Weiran, he didn't care what he could learn at all.Looking at these obscure results, Zhuang Weiran felt a headache for a moment.Putting down the notebook, he rubbed the space between his eyebrows.He still needs a richer knowledge and understanding now to understand the thoughts of Grothendieck, the great geometric and algebraic god.

Putting down the notebook in his hand, those obscure words made him dizzy.I was able to calculate it repeatedly before, but now I can hardly even understand it, let alone calculate it.He can only start to calculate according to the calculation of this God.

But when the calculation reached the middle, Zhuang Weiran felt that he couldn't count at all.Comparing the contents in the notebook, he finally began to feel that this great mathematician was really not joking.

Mr. Pope, who was able to lay the groundwork for modern geometry and algebra, did not just stop at the stage of bragging.He had read the fragments of this gentleman's research results before, and they were all extremely profound research. At least he could understand them. This gentleman has lived in the Pyrenees for so many years.Meditation and mathematics have improved several realms again.

Zhuang Weiran can say without hesitation that he is one of the most outstanding and top mathematicians in the world.He couldn't even understand the obscure text, and he finally knew why Grothendieck didn't let him show it to others.

As far as the contents of this notebook are shown to others, it is estimated that everyone will lose confidence in mathematics.He needs to absorb more knowledge, and access to Grothendieck's thinking.

He did not give up understanding Grothendieck's thoughts. Since the master solemnly handed over all these achievements to him, he must absorb them all and make good use of them.It has to be said that when he thought he had a bottleneck in mathematics.Grothendieck's academic achievements and achievements are like a bright light to him.

Shining on his path, perhaps, he still can't fully understand all the thoughts of this master.But Zhuang Weiran can guarantee that after he fully understands the thought of this master, he may really be able to bring mathematics into a new field.Vaguely, he felt that the master had already touched the door, and he only needed to take a few steps forward.

Gently push the door open, maybe there is a brand new world outside the door.

Unfortunately, the master's time is numbered.If the master had been given a little more time to live, he might even have literally brought mathematics into a whole new world.

Rubbing the notebook with his hands, he didn't speak.He is thinking now, after reading these academic achievements, Zhuang Weiran does have a more profound understanding of algebra and geometry.What happens if you use these things as an Abelian field?Zhuang Weiran is very curious. Since the last century, Hilbert's 23 questions have been a puzzle that all mathematicians are keen to solve.But more than a century later, Hilbert's 23 questions still have many questions that have not been solved.

What is Uncle Problem, this is Uncle Problem!For more than a century, countless mathematicians have studied the questions he raised, and there are still many unanswered questions today, and there is still a long way to go before the final answer to the question.Unfortunately, the extension of Crocker's theorem on the Abel field that Zhuang Weiran needs to do is the type that is still a long way from the final answer to the question.

But Zhuang Weiran has already shortened this road a lot. Once his undisclosed achievements are made public, they will definitely cause a sensation in the global mathematics circles, and even turn everyone's eyes away.

Uncle Hilbert, known as the uncrowned king of mathematics in the [-]th century, was born in the Göttingen School of Mathematics.At that time, the Göttingen School of Mathematics was the center of mathematics in the world, just as Princeton is the center of mathematics now.

The Göttingen School has produced countless geniuses, such as Gauss, Klein, and Hilbert. Even in the last century, the Göttingen School still has countless geniuses.For example, Albert Einstein, von Neumann, Richard Courant and so on.

And as these geniuses went to the lighthouse country, the Göttingen school began to decline, and the mathematics of the lighthouse country ranked a leading position in the world. Only then did Princeton replace Göttingen as the world's mathematics center.

Interestingly, Grothendieck, the master known as the pope of mathematics.Also once studied in another school in France.The Bourbaki School, this master once joined the Bourbaki Group, and was influenced by the founder of the Bourbaki Group, so he can be regarded as a figure of the Bourbaki School.

Of course, in modern society, these schools of thought are just interesting to hear.Schools such as Göttingen and Bourbaki have long since ceased to exist.

When Zhuang Weiran thought of Hilbert, he suddenly thought of a famous school in history.

Forget it, since he hasn't understood the results of this master, and he hasn't even had time to read the complete "Draft Program" later, Zhuang Weiran spread out the draft paper.The current research on the Abel field has been considered very in-depth, and now he needs to study this issue more in-depth.Take a pen and start writing calculation formulas on the scratch paper.

Lin Sen is in the living room, looking up literature on gauge theory.

"Grandpa?" Lin Sen was a little flustered when he received the call.

"How does Komori feel at Princeton University?"

"It's great." Lin Sen said with a smile, "Now I'm living with my cousin Rui Ning. Today I went to see Professor Wei Teng, and he also agreed to let me study for a Ph.D. with him."

"This is a good start. Weiteng is at the top level in the world in mathematics and theoretical physics, and is especially good at solving problems in theoretical physics with mathematics. You should study hard with Professor Weiteng." Chen Zhong He is very clear about the professors at Princeton University, especially these old professors. When he was at Princeton University, he might even have brought some of them.

Lin Sen was brought up by him since he was a child. He Ruiming had no choice but to follow his father to become a policeman since he was a child.When He Zhenguo and Chen Xinyao got married, he didn't like He Zhenguo.How did an ignorant bastard get his daughter to like him?Every time he sees He Zhenguo, he blows his beard and stares, but he really wants his daughter to fall in love with his student.But his daughter doesn't like it, she just likes He Zhenguo, a bastard who is not well literate.

In those years, Chen Zhong was also very angry.But He Zhenguo was really kind to his daughter, he never blushed, and Rui Ning was abducted by someone so big, he would never be cruel to his own people.

It was that He Ruiming really made Chen Zhong hate iron for being weak, and he couldn't teach him no matter what, so he insisted on being a policeman.Chen Zhong was so angry that he stomped his feet. If it wasn't for Lin Sen, he would definitely chase He Zhenguo and beat him up.

It's really irritating, but luckily Rui Ning is the best one in their family now.

"But Grandpa." Lin Sen said cautiously, "Professor Wei Teng asked me to learn functional analysis and gauge field theory from Rui Ning."

Chen Zhong said without hesitation, "Rui Ning has the top international level in functional analysis and gauge field theory. I heard that he and Professor Wei Teng have some theoretical conflicts. I guess Professor Wei Teng wants to let You win the head of a hundred schools."

"Study hard, and don't leave behind both mathematics and physics."

"I'm currently looking at the literature and materials on gauge theory." Lin Sen sighed, "Grandpa, I think I may not be graduating too soon."

"Five years is enough for you to learn. You are still very talented. Your parents also worked in this field. Rui Ning has not had the qualifications like you since he was a child." Chen Zhong said, "Give it to your father." Did mom call?"

"Fight." Lin Sen looked at the documents, "Grandpa, then I will continue to study."

"Study hard." Chen Zhong hung up the phone, Lin Sen looked at the documents and materials seriously, and didn't know what kind of subject his cousin would assign him.Just let him read the documents and materials first, without any purpose, just looking at it like this, Lin Sen felt a little awkward.In the past, when he read these documents, he always had a purpose. He had a plan for what he needed to find and what he needed to study.Now that there is no such plan, he just looks at it aimlessly, which really makes him not used to it.

A few days later, Zhuang Weiran basically didn't go out much, and stayed at home to do research. Lin Sen thought it was amazing that Zhuang Weiran could really stay in the house all the time, and he really didn't go to other places except for parties. .

Lin Sen also needs to go to the library to look at documents and materials, and then go out for a stroll and so on.Zhuang Weiran stayed at home and hardly ever went out. Either he had to go to class, and he had to explain difficult problems to the students for half a day before going out.

Even Pierce, Zhuang Weiran's student, hasn't seen the professor for a long time.

Every time I asked Zhuang Weiran a question, I had to leave Princeton University and go to his residence.However, now Pierce likes to come to Zhuang Weiran's house very much.Because the food cooked by the professor was so delicious, he felt that the things provided by the school were hard to swallow.Or the food made by the professor is delicious.

He would come to Zhuang Weiran's house every two days to grab a meal, and as soon as the doorbell rang, Lin Sen didn't have to think about it, it must be Pierce who came to eat.

Sure enough, the door was opened, and Pierce was standing outside with a lot of things.

Lin Sen felt it was funny, "Why don't you just live here?"

"No, this is the professor's house." Pierce shook his head, "Where's Professor Zhuang?"

"I'm doing research upstairs." Pierce came to the table and put down the documents, materials, computer, and his draft paper.

"Lin." The two were very familiar. It was already November and the weather was getting colder and colder.The two knew each other before, and Pierce came to Zhuang Weiran countless times in the past month or so, which can be regarded as forging a deep friendship.

After Lin Sen sat down, he lowered his head and began to do calculations, "Did the professor give you the subject?"

"Yes, the subject of Banach space and gauge field theory." Lin Sen frowned. This subject was more difficult for him.

"What about your subject?" Lin Sen asked Pierce with concern, "I've seen the subject for you, and it seems to be difficult, right?"

"Yes, homology algebra is indeed very difficult, but fortunately, you can continue." Pierce smiled, "How about you, can you continue? I see that you have been sad for several days, it is too difficult." ?”

"It's not particularly difficult." Lin Sen shook his head, "Well, there are still some things I haven't been able to understand."

Pierce understood, "Actually, I really don't know much about the gauge field theory. You still have to ask the professor to give you some advice.
