Hearing what the professor said, he knew that the professor must have some questions about partial differential equations that he wanted to ask him.

"Professor, you are the same as Professor Feffman. A few days ago, he always asked me questions about partial differential equations." Zhuang Weiran scratched his head, revealing this question inadvertently.

"Feffman?" Ji Lao snorted coldly, "Isn't he a fluid dynamics scientist? He has been studying partial differential equations for so many years. What else can I ask you?"

Professor Ji's previous research was on algebra and number theory, but he didn't have much research on applied mathematics.It is estimated that it is not needed by the country. Professor Ji must still be studying number theory, not partial differential equations.

"Let's talk about it when we get to the hotel." Professor Yan is a professor of physics, and Professor Ji is a professor of mathematics. They came together and asked him to go back to the hotel to talk about it. Zhuang Weiran already understood this matter.It is estimated that the country is studying the topic of fluid mechanics, but the research of the two people is a bit difficult. It is estimated that this is just seeing myself, thinking that he is not bad in partial differential equations.

So I want to discuss it with him.

"Ahem." Zhuang Weiran spread out his hands, "Professor, the discussion is fine, but I really can't participate in it."

"Don't worry." Professor Ji patted his chest and assured, "Xiao Zhuang, I promise you are fine."

"Professor Ji, of course I don't worry." Zhuang Weiran nodded, "But you also know that I studied mathematical physics with Professor Tao. I have never done any experiments in fluid mechanics, and I am not familiar with flow fields. , I just want to help, I'm afraid it's just talking on paper."

"Sometimes, theories and calculations are often inconsistent with reality. Mainly, theory and calculations are all in a perfect state, but reality always has problems of one kind or another."

"Of course I know." Professor Ji hummed and said, "I've been doing scientific research all my life, so I still don't know about these things."

Professor Yan followed the two and said, "Professor Xiaozhuang, don't worry, it's really just a partial differential equation, which can't represent anything."

"Okay." Zhuang Weiran nodded, accepting it.It is estimated that the two professors would not want to discuss this issue with him, who is still at Princeton University, if there is no other way.

Sitting in the car, Zhuang Weiran came to Thief for the first time, but he has no interest in Thief.Without looking sideways, Ji Anyi next to him looked around, as if he was curious about everything.

Zhuang Weiran turned to look at Ji Anyi and said, "You seem very excited."

"No way." Ji Anyi firmly refused to admit that he was very happy.

"You don't like stealing the country, do you?" Zhuang Weiran turned his head and glanced at the scenery outside the window. To be honest, there was nothing special about it, and he didn't know where Ji Anyi's excitement came from.

"No, no, no." Ji Anyi shook his head hastily, what a joke, he likes stealing countries, how could he like stealing countries.It's just that he has been studying before and has never been abroad.

"You don't even know." Because only Zhuang Weiran is about the same age as him, Mr. Ji is his grandfather, and Professor Yan is also in his 50s and [-]s.The reception group is from Neon, so naturally Ji Anyi can only chat with Zhuang Weiran, "The last time I went abroad was when I participated in the imo competition."

"Oh?" Zhuang Weiran looked at Ji Anyi, "Have you participated in the imo competition?"

"I have participated." Ji Anyi said with a sigh, "But after I went to college, I studied physics. When I took the postgraduate entrance examination, I also wanted to continue studying theoretical physics. Unexpectedly, I was dragged by the old man to study mathematics."

"Learn about mathematical physics." Zhuang Weiran said with a smile, "If you have learned mathematics well, general theoretical physics is no problem."

Ji Anyi sighed, "Master, you are a master, the mathematical physics you study and the mathematical physics I study are not the same thing at all, let's take partial differential equations as an example, I have a headache now. But I know , Dashen is very good at this. Dashen used to study number theory when he was an undergraduate, and you started to study partial differential equations when you were studying mathematical physics with Professor Tao, right?"

"Not really." Zhuang Weiran thought for a while, "Before that, I had already started to study partial differential equations, but I didn't do any in-depth research. It was indeed when I was with Professor Tao that I started to study this in depth. thing."

"No." Ji Anyi's face looked a bit wrong, "Sure enough, the Great God is different from me and other mortals. I have also studied partial differential equations before, but when I come into contact with it now, I am completely confused. Stupid."

"Actually, partial differential equations are pretty easy to solve. If it wasn't for limit partial differential equations, you wouldn't be able to do this after studying physics for so many years."

"It's different, it's really different." Ji Anyi cried bitterly, "I feel that I have studied very hard, but I still haven't been able to learn."

"Take it easy." Zhuang Weiran said with a smile, "The limit partial differential equation is indeed a bit difficult."

When the car was safely parked at the hotel, Zhuang Weiran and Ji Anyi got out of the car first. Zhuang Weiran opened the door and waited for Professor Ji to get off the car. After getting off the car, Professor Yan was also waiting for Mr. Ji.

Professor Ji got off the car, and Zhuang Weiran was by his side.

Occasionally, a professor from the Department of Mathematics of Princeton University passed by and greeted Zhuang Weiran, "Hey, Zhuang!"

Zhuang Weiran checked in with Professor Ji with a smile, and then sent Professor Ji back to the room.Only Professor Ji, Professor Yan and him were in the room.

Ji Anyi is drinking coffee below, which is also Professor Ji's meaning.

Holding the draft paper, Professor Ji wrote down a calculation formula, "Xiao Zhuang, let's take a look, what should this formula do?"

Zhuang Weiran took a look at the formula, and instantly remembered the formula that Professor Feufman had shown him before. This formula cannot be said to be exactly the same, but there are some similarities.

He didn't tell Professor Ji about this, but just started to write the calculation steps on the draft paper. When he was about to finish his meal, Zhuang Weiran raised his head and said to Professor Ji, "Professor, look at my pair." No. It should be like this."

"Let me take a look." Professor Ji took the draft paper and said to Zhuang Weiran, "Xiao Zhuang, don't you have something to do today?"

"Yes." Zhuang Weiran nodded, "There is a party, but it doesn't matter if you go later."

"You kid, I stayed abroad for half a year, and I didn't learn it well, but you learned it very quickly because foreigners like to party."

Professor Yan said next to him, "Mr. Ji, Professor Xiaozhuang is only in his teens. We like to play at Xiaozhuang's age."

"That's right, but after playing for fun, you have to do serious things." Professor Ji never took his eyes off the draft paper, but he still told Zhuang Weiran.

"I know."

"You guys know." Professor Ji turned the page and continued, "I heard that the theme of your academic report is the weak Goldbach conjecture. How are you doing?"

"There is a breakthrough. The paper has been sent to the organizing committee a few days ago."

"That's good." Professor Ji nodded, and he breathed a sigh of relief, "I heard that your kid wants to solve the weak Goldbach's conjecture at the academic report meeting, which is too risky. I have never I agree, Xiaozhuang, you know."

"I know." Although he has not been studying with Professor Ji for too long, Zhuang Weiran knows exactly what kind of personality Professor Ji is.He has always disapproved of students eager for quick success. Zhuang Weiran's reckless attempt to solve the weak Goldbach's conjecture at the academic report of the International Congress of Mathematicians is a manifestation of eagerness for quick success.

Professor Ji believes that Zhuang Weiran can indeed be ranked among the world's top mathematicians now, but at the same time, he has to work steadily.

Not long after solving the Millennium Prize puzzle, he wanted to solve the weak Goldbach conjecture, one of the world's puzzles.It's really a bit eager for quick success, and Zhuang Weiran is not omnipotent. If a person's strength is strong, how strong can he be.In addition, there are too many branches of modern mathematics, and there are many subdivisions of subjects.

It is impossible for Zhuang Weiran to be omniscient, and he may be particularly outstanding in one aspect.Correspondingly, it may be unsatisfactory in some respects.

Whether it's mathematics or scientific research.After all, they are all humans, not gods, and the concept of omnipotence does not exist.

Otherwise, if you ask Zhuang Weiran some questions about chemistry or physiology, he promises to know nothing.

"So, I am also in favor of your boy going to Princeton University." Professor Ji paused, "You should go out and see the world, and there are not many people in Huaguo who can discuss mathematics with you. But Princeton University is different. There are many top masters, and there are also many who can discuss mathematics with you."

"But mathematics, firstly, depends on talent, and secondly, you need to work hard. You are very talented and have achieved good results, but I hope you will not be satisfied with this. You must make more and better things. Grades, this is my expectation for you!" Professor Ji turned the page again, "Which teacher doesn't want his students to be more outstanding. I not only hope that you can be a world-class mathematician, but also that you can become the top mathematician .Who said there are no mathematicians in China?"

"Professor, the students will never let you down."

"You have never let me down. It's just your temperament. I think it's time to polish it." After Professor Ji finished speaking, he continued to turn the page, "It will take a few days to calculate this formula, Xiaozhuang, you go first Go about your business."

"Okay." Zhuang Weiran nodded, leaving the room and closing the door softly.

"Come on, Lao Yan, take a look." Professor Ji put the draft paper on the table, "If he comes to do this part, we should be able to solve this problem soon. It's a pity, this kid is now in Princeton University, even if we want to find him, there is no way."

Professor Yan held the draft paper and looked at it silently. Not to mention, Zhuang Weiran's thinking was very clear, and the steps to solve the problem were also very detailed.The key is that he solved the problem very quickly. He almost started to write the proof after reading the equation, and he solved the problem that had troubled them for a long time without spending much effort.

"The speed is very fast. If our project is done by Professor Zhuang, it should be able to finish it several years faster than us." Professor Yan smiled and shook his head and said, "Professor Zhuang is indeed very powerful."

"Let's put it this way, I don't think Xiaozhuang has any weaknesses in number theory, partial differential equations, algebra, geometry." Professor Ji also said with a smile, "It's a pity that he is not in Huaguo, otherwise, he must be appointed as the leader of this research group." Team leader, much better than me."

"Professor Ji, you can't underestimate yourself like this. You are able to train students like Professor Zhuang, which already shows that you are very good."

"Those who can teach are not necessarily the most powerful people. What's more, I am not very good at teaching. It all depends on Xiao Zhuang's self-taught."

"You are joking, even if Professor Xiaozhuang started learning mathematics from the womb, without your guidance, he would not become the current Professor Xiaozhuang." Professor Yan said with a smile, "It's a pity, Professor Xiaozhuang doesn't know when to return home."

"Yes." Professor Ji also sighed, and the time for Zhuang Weiran to return to China is far away.No one dared to ask Zhuang Weiran when he would return to China, besides, Zhuang Weiran had not been abroad for a long time.

Zhuang Weiran used to help professors deal with some projects and subjects at Peking University and China University of Science and Technology, but basically these subjects and projects had nothing to do with the government or the military.

But at Zhuang Weiran's situation, if he is abroad, it is hard to guarantee that many research institutions will not invite him to participate in some projects.And foreign private research institutions will also cooperate with foreign military or government.

In this way, it will be even more difficult for Zhuang Weiran to return to China.

However, Professor Ji also knows very well that at Zhuang Weiran's level, it is almost impossible for Zhuang Weiran to improve except for the world's top mathematics research institutions or schools.

So naturally, there are not many places Zhuang Weiran can go to, and Princeton is considered the best place among them.

The academic tower is not just talk.

"We still have a lot of calculations, and we can't show them to Professor Xiaozhuang at all. Otherwise, I believe that Professor Xiaozhuang can do all these calculations in a few days, which can save us more than half a year." Professor Yan held The draft paper is amazed, they need half a year or more to calculate, I am afraid Zhuang Weiran can complete it in just a few days.

This is probably the difference between people who are gifted in mathematics and ordinary people. It is not uncommon for Ph.D. students from the School of Mathematics of the University of Science and Technology of China to participate in this project, but their progress is not too fast. Zhuang Weiran directly solved the problem. They have not been able to solve the problem for half a month.

If Zhuang Weiran is allowed to go to the research group, I am afraid that the military will have to come and snatch people from them!

After leaving Professor Ji's room, Zhuang Weiran first went back to the room to put down his things, and then contacted Professor Feffman.Professor Feufman told him very excitedly that he would introduce a friend to him today. It was probably that Professor Feufman was listening to an opera while drinking coffee with a loud voice.Zhuang Weiran was going to have a meal first, when he opened the door, he saw a young man with European and American appearance was about to knock on the door.

Zhuang Weiran looked at the man in astonishment and said, "Who are you looking for?"

"Zhuang, Professor Zhuang." The man blinked, "Are you Professor Zhuang from Princeton University?"

"I'm Zhuang Weiran." Zhuang Weiran looked at the young man in a daze, "What can I do for you?"

"Hi Professor Zhuang, I am a student of Merton College, Oxford University."

"Merton College?" Zhuang Weiran frowned, feeling amused.

The founding of Merton College can be traced back to 1264, when W. Merton (Walter Demerton), the Lord Chancellor of Great Britain, decided to create an independent academic organization, establish a foundation, and formulate relevant regulations. prototype.The characteristic of this regulation is that it stipulates that Merton College is self-governing, and the funds are directly controlled by the dean and academicians. This is the characteristic of most independent colleges in Oxford University today**.

"Oh, what can I do for you?"

"Professor Zhuang." The young man was blond and blue-eyed. He looked much stronger than Zhuang Weiran, but he was a little shy.

"Professor Feffman asked me to invite you to the party."

"Oh!" Zhuang Weiran nodded, just after calling Professor Feufman, the opera was quite loud there, so the party has already started?What kind of party, an opera party?He himself doesn't have any appreciation for opera. Wouldn't it be nice to make a few more mathematical conjectures when he has that time?

But he will not hold any objection to other people's hobby, it is other people's business and has nothing to do with him.

"Just now I finished the phone call with Professor Feffman. Is there an opera party over there?"

"No." The young man scratched his head. "You must have misunderstood. It's not an opera party. Professor Feffman just went there too. He called me and asked me to invite you to attend."

"Who are the people attending the meeting?"

"There are many mathematicians." The young man smiled, looking forward to it, "There are many people."

"Then wait a minute, are you at the hotel?"

"Yes." The young man nodded heavily, "It will be held in the backyard."

"All right, wait for me to clean up." Zhuang Weiran closed the door, changed into a more formal attire and opened the door, seeing the young man standing outside the door, he asked with a smile, "Are you at Merton College?" Math?"

"Yes." The young man nodded happily, "Professor Zhuang, you are very famous, and our Merton College students all hope that you can arrive at Oxford University and give a grand academic speech."

"what's your name."

"Jerome Pierce."

"Mr. Pierce, who are you?"

"Master of Science."

"Is the math right?"

"Yes." Pierce nodded vigorously, and said eagerly, "Professor Zhuang, can I go to your place to study for a doctorate?"

"Ah?" Zhuang Weiran froze for a moment, turned to look at Pierce, and said with an incredulous expression, "Mr. Pierce, you are at Oxford University, which is one of the best universities in the world. Why do you want to come to Princeton University? Study with me?"

"Princeton University has a lot of well-known professors." Zhuang Weiran continued, "To them, I am nothing at all."

"Professor Zhuang, you are already very famous, and you are already very good. We all think that your mathematics level has reached the top in the world. Besides, you are in the prime of life, and you still have a lot of time to do various projects. I want to study with you , follow you to do more subjects." Pierce said straight to the point, "My tutor is Mr. Wiles."

"Wiles?" Zhuang Weiran was slightly surprised, "Mr. Andrew Wiles?"

"That's right." Pierce nodded vigorously, "I want to study with you, Professor Zhuang, during my PhD."

"But Mr. Pierce." Zhuang Weiran paused for a moment, and carefully looked at Pierce, this unattractive-looking young man, "Maybe you won't be able to participate in my project, or in other words, I don't intend to let my students participate in my project." Projects. I still prefer to do projects alone, because the feeling of quietly thinking about problems makes me feel great."

"But Professor Zhuang, maybe you need an assistant. I want to study mathematics with you because you are already a world-class mathematician. There is an old saying in your country of China, 'When you hear the Tao, you can die at night'. I believe that, From Professor Zhuang, I can learn a lot of things that I haven't fully understood before."

"Mr. Pierce, it seems that you came prepared." Zhuang Weiran raised his eyebrows, "But I'm just an associate professor at Princeton University now, aren't I?"

"But Professor Zhuang, you will soon become a professor at Princeton University and a doctoral supervisor."

"Eh..." Zhuang Weiran was puzzled, "Why do you all know about this? I suspect that someone has been spreading the news."

"Professor Zhuang, you are already one of the well-known mathematicians. Everyone pays attention to your news immediately. As long as you are studying and researching mathematics."

"But Mr. Wiles is a mathematician who solved Fermat's last theorem. It is no exaggeration to say that he is one of the greatest mathematicians in the world. Why don't you continue to study with Mr. Wiles?"

"This is also the suggestion Mr. Wiles gave me. He thinks that I can learn more knowledge from you. Mr. Wiles said that he has given me all the knowledge that he should give me. If you want Find a professor, he hopes it's you."

"Me?" Zhuang Weiran didn't quite understand, he and Mr. Wiles had never met, why Mr. Wiles wanted his students to study with him.

"Have you figured it out yet?"

"Not yet." Pierce also shook his head. After thinking for a long time, he still couldn't figure out the reason why Mr. Wiles did this.

"Mr. Wiles has come to steal the country?"

"Yes." Pierce nodded and said, "Mr. Wiles is also going to this party, and it should be almost here now."

That being the case, if there is any question, he should ask Mr. Wiles back then.

Taking the elevator to the first floor of the hotel, Pierce led Zhuang Weiran to the backyard.When I came to the backyard, there was a lot of people here, and someone was sitting in the middle playing the violin.Countless men and women were talking together, Zhuang Weiran was still a little uncomfortable with this atmosphere.

He straightened his clothes and entered the party with Pierce.

Looking around, everyone seems to be very happy.At this time, an old man blocked Zhuang Weiran's footsteps. He raised his glass and said to Zhuang Weiran, "Zhuang?"

As soon as the words fell, the men and women who were almost still chatting turned their heads and looked at Zhuang Weiran in unison.

Although Zhuang Weiran's photos have been widely circulated, Princeton University still has his photos.But looking at photos is not the same as seeing people in person.

At this moment, Zhuang Weiran was embarrassed.

"You are Zhuang, right?" The old man said with a smile, "I didn't expect to see you here."

"This is your first time participating in the International Congress of Mathematicians."

Zhuang Weiran smiled awkwardly, "You are?"

"Yokoz."

"Oh, so it's Mr. Yorks." This is also the winner of the Philippine Award, he patted Zhuang Weiran on the shoulder and said, "Zhuang, how are you, how do you feel?"

"Eh? What aspect are you talking about?"

"Participate in the International Congress of Mathematicians."

"It's...not bad." The corner of Zhuang Weiran's mouth twitched. With so many people staring at him, he also felt very stressed.

"have a drink?"

"I don't drink." Zhuang Weiran shook his head and said, "Sorry, Mr. Yorkz."

"Let's have a glass of juice." Yokez said with a smile, "Zhuang, you are now a big celebrity in the mathematics world."

Before Zhuang Weiran had time to ask why you are a big celebrity, Yorkz whispered in Zhuang Weiran's ear, "Zhuang, everyone is saying that you can win the Fields Medal this year."

"Eh..." Zhuang Weiran spread his hands, "I don't care if I said it. When Mr. Yorkz won the Fields Medal, did the organizing committee tell you in advance?"

"Not really." Yorkz said with a smile, "However, for the Fields Award, cheers!"

Yorkz raised his glass high, Zhuang Weiran had no choice but to drink a glass of juice with Yorkz.As soon as the cup was put down, someone came forward to strike up a conversation, someone asked Zhuang Weiran about number theory, and someone wanted to invite Zhuang Weiran to dance.It made Zhuang Weiran's headache so bad that he couldn't understand why he became so popular all of a sudden?

When I was at Princeton University, it was not like this.

"Zhuang." Professor Feffman's voice was a little louder, "Everyone, Zhuang and I still have something to say."

Then Professor Feffman pulled Zhuang Weiran away, leading him away from the crowd.

"I didn't expect, Zhuang, to be so popular." Professor Feffman said in a joking tone, "I was still thinking about looking for you just now, if Pierce hadn't told Professor Wiles that you were surrounded by the crowd, I would have Thought you weren't here."

"This..." Zhuang Weiran turned his head to look at a large group of people, talking and laughing, but he couldn't figure it out, "Professor Feffman, what do you think is going on with them?"

"Don't you want to see what this year's Philippine Award winner looks like?" Professor Feffman was still teasing Zhuang Weiran, which made Zhuang Weiran very embarrassed.

"Professor, don't say that." He scratched his head and said, "I don't even know when the Philippine Award will be awarded to me."

"Let's go, Zhuang." Professor Feffman said to Zhuang Weiran, "I'll introduce you to a friend."

With that said, he led Zhuang Weiran to the corner.

"Professor Wiles, a professor at Merton College, Oxford University, also served as a professor at Princeton University." Fefferman introduced, "I believe I don't need to say, Zhuang, you also know Professor Wiles."

"Hello, Zhuang." Professor Wiles stretched out his hand in a friendly manner. Zhuang Weiran shook hands with Professor Wiles, "Hello, Professor Wiles, I have heard about your reputation and deeds many times."

"It's like thunder."
