After everything was decided, Junxin stopped and turned to leave Professor Wiles's house.

Although it was decided that he would join forces with Professor Wiles to prove Fermat's theorem, Junxin and Professor Wiles' approach was slightly different. After all, Professor Wiles was influenced by the academic climate in Europe and chose to go it alone. But this does not mean that Junxin, as a collaborator, has to fight alone.

So after a day off to regain his spirits, he sought out Professor Charles Feverman, who was the chair of the Department of Mathematics at Princeton University and a professor in the School of Mathematics at the Institute for Advanced Study in Princeton.

In fact, the exchange between Junxin and Professor Feverman is relatively rare in the Department of Mathematics of Princeton University and even the School of Mathematics of the Institute for Advanced Study. The reason is very simple, Professor Feverman is more often studying his subject, and as a top algebra expert, although his understanding of geometry is far beyond that of ordinary people, he is only based on the knowledge of his huge mathematical system, and when he really communicates with Junxin, there are always great limitations.

Of course, as a professor, from the perspective of professors and students, Professor Feverman is very satisfied and appreciative of Junxin's talent, which is an important reason why Junxin can enter the special afternoon tea meeting organized by the professors of the Department of Mathematics.

According to the afternoon tea rules of the mathematics department at Princeton University, both professors and students organized by the students can participate, but in the other professors' afternoon tea meetings, only professors from the mathematics department can participate. Junxin was able to participate in the professor's afternoon tea party because he was invited by Professor Charles Fefferman, who is the head of the Department of Mathematics at Princeton University.

In addition, at Princeton University, the Department of Mathematics is one of the most prominent disciplines, and the direct leader of its department, Professor Charles Feverman, is also very powerful. The identity of Junxin's exchange student in the Department of Mathematics was naturally determined after the approval of Professor Feverman.

Therefore, Junxin still has a sense of gratitude to Professor Feverman. As someone who is about to leave, Junxin is not only seeking the help of Professor Feverman, but also with gratitude.

Professor Feverman is a very traditional new academic leader, and the reason why he is called traditional is because he follows all the good traditions of academia, which is cautious, serious, persistent and mechanical. He is said to be new because he can accept new ideas and views, is not stubborn, and likes to promote the next generation, the famous mathematician Tao Zhexuan entered Princeton, in fact, there are reasons behind his promotion.

For such a respected professor, although the two do not have much in common because of the issue of professional direction, Junxin still values Professor Feverman's opinions and suggestions. This time was no exception.

"It's rare for you to come to me, tea or coffee?" Professor Feverman was a little surprised by Junxin's arrival, but Junxin could see that Professor Feverman was still very welcoming to his arrival.

"Let's tea!" Junxin doesn't like coffee very much, and coffee is like a hypnotic thing to him a lot of the time, and it doesn't have a refreshing effect at all. Therefore, Junxin has never had any feelings for coffee, and has always used tea as a drink.

"Then you'll have to prepare yourself, on the table over there!" Professor Feverman is an orthodox Westerner, so he naturally prefers coffee, so although he prepared tea leaves, he did not brew them.

Seeing that Feverman was still dealing with some things in his hands, Junxin shrugged his shoulders and stood up, walked to the coffee table, took out the tea leaves, and brewed them himself.

When Junxin poured the tea into the cup, Professor Feverman also finished his work, walked to the coffee table and sat down, and said, "After coming to Princeton for such a long time, this is the first time you have taken the initiative to find me, right?" In fact, I thought you were going to go to Professor Thurston for something! ”

Of all the Princeton universities and institutes for advanced study, it is a well-known fact that Junxin and Professor William Thurston have the best relationship, according to Professor Feverman.

Jun Xin shook his head and said: "Maybe I'm more interested in geometry than algebra, especially about superstring theory, some things in topology have a lot to do with it, looking at Princeton, Professor Thurston is an authority in this area, I often go to him to discuss problems has made you habitually think that I have any problems to find Professor Thurston?" ”

"Haha, just kidding!" Professor Feverman explained with a smile and asked, "So, in your Oriental saying, you don't come to me just to drink this cup of tea, do you?" ”

Hearing this, Jun Xin put down the teacup in his hand, and said solemnly: "I did come here for some things to ask you for help!" ”

"Tell me about it!" Professor Feverman waved his hand, "If it's an academic question, I can only give you some professional advice!" ”

"You are too modest, although your main achievements are in algebra, but your research in other directions is also very admirable to us!" Jun Xin shook his head and said seriously.

In this day and age, it is not necessary for two people to be able to communicate with each other if they are mathematicians. This involves the question of direction, one who specializes in algebra and the other who specializes in geometry, although they are both mathematicians, but there is absolutely not much room for communication, and they are not even as good as a geometer and a physicist.

Because of the high development of mathematics, mathematicians are becoming more and more specialized and niche, and the absolute professionalism of mathematics makes people who communicate more and more tend to the same direction or related direction. This is also the reason why Junxin knows that although Professor Charles Feverman in front of him is a world-class mathematician who has won the Fields Medal, he has very little communication.

But Junxin knows that although the serious professor in front of him has achieved mainly in algebra, his achievements in other aspects are not low at all, at least he can keep up with the ideas of other top mathematicians.

However, the people who communicate with Junxin are basically top mathematicians in various fields, although they are not as good as Professor Feverman in algebra research, but they are far better than Professor Feverman in their respective fields. Naturally, Professor Feverman rarely speaks in areas that he is not good at, which is why Junxin rarely communicates with Professor Feverman.

"Okay, let's talk about it, what's the problem?" Professor Feverman didn't waste much time on the pleasantries, and asked digressively.

"I would like to ask you what you think of Fermat's theorem!" Junxin also put away his smile and asked seriously.
