After taking two steps, Xu Chuan suddenly remembered another question.

He stopped and looked at Paxia Mirith, who was standing still, and asked curiously, "I remember you just said that you studied under Professor Marianne Mirzahani?" ”

Paxia Miris thought that there was room for things to turn around, and her eyes lit up, and she walked over quickly.

"That's right, my mentor is Mirzahani."

"You say you're a Ph.D. student at Princeton? But if I'm not mistaken, Professor Marianne Mirzahani seems to be at Stanford University, right? ”

Xu Chuan asked a little strangely, why did Professor Marianne Mirzahani's students come to Princeton?

Exchange students?

No, for most people, if they can study under a Fields Medal winner, this is almost the best choice, and there is no need to exchange to Princeton to study at all.

Hearing this, Pahia Mireis shook his head and said with some loss: "Professor Mirzahani was my supervisor in graduate school, and I came to Princeton when I was 12 years old. ”

Xu Chuan suddenly understood that the girl in front of him was really a little unlucky.

She studied with Professor Marianne Mirzahani in graduate school and went to Princeton for 12 years, but then won the Fields Medal just two years later.

Although going to Princeton for further study is a good choice and you can learn a lot, correspondingly, following a Fields Medal mentor can get more resources, status, and more.

Not everyone can compare himself to himself, and he was able to study with two Fields Medal winners after entering Princeton.

I think that the girl named Pahia in front of me just missed this opportunity.

.........

Back in the dormitory, Xu Chuan cleaned the dormitory and sorted out the luggage he brought over.

Princeton University still has quite sufficient resources, such as accommodation rooms and so on, and there are five residential colleges in the dormitory alone.

Each residential college includes a series of dormitories, a cafeteria, and other facilities such as study rooms, libraries, stages, dark rooms, and more.

But there are still a lot of single rooms like him, but not everyone can apply for them.

Even if you are a doctoral student in Princeton, if you apply for accommodation without the help of your supervisor, you will most likely only be able to apply for a double or triple room.

Xu Chuan does not have high requirements for accommodation, he can accept a double room or a multi-person room, but a single room is obviously better.

After all, sometimes he often stays up late or even all night when he is studying or studying, and if he lives with others, it will definitely affect others.

There is no such trouble in the single dormitory, and he can toss and turn as he wants.

After briefly cleaning the room and tidying up the luggage he brought over, Xu Chuan got up and went downstairs to go to the off-campus dining club for dinner, and then went to sleep to adjust the jet lag.

Princeton University is the only Ivy League school located in a village or town known for its food, and this school is famous for its unique celebrity chef visits, where you can taste the specialties cooked by famous chefs on campus every week.

But unfortunately, these well-known chefs are basically chefs of all kinds of Western food, and they don't know Chinese food.

If you want to eat Chinese food in Princeton, you have to go to some of the special 'restaurants' near the campus, or special 'food clubs', which only serve Chinese food.

He has been here for more than ten years, and he naturally knows where the food tastes best for him.

However, Xu Chuan underestimated his influence a little, and when he appeared at the Daqian Food Forest Restaurant outside Princeton and was recognized, the whole restaurant immediately became agitated.

Mr. Xu underestimated the allure of an 18-year-old Filipino Prize candidate for a mathematics professor at Princeton University.

In particular, when these professors basically learned that he would come to Princeton to study, they had already told their assistants or students that if they met him, they must recruit him.

So while eating, Xu Chuan encountered people constantly coming up to talk to him, hand over business cards, and recommend mentors.

After eating a meal, he received more than a dozen business cards.

One of them was handed to him by the owner of the Daqian Food Forest restaurant.

The boss is a Chinese, five big and three thick, but the cooking skills are very high, in the cooking of fish, whether it is water fish, or sea fish are very powerful.

In particular, the boiled fish fillet can be said to be an authentic hometown taste.

Unfortunately, the vast majority of Princeton students don't eat much boiled fish made with grass carp, tarpon and blackfish.

In the eyes of the vast majority of foreigners, Chinese food is either too spicy, too salty, or too tangy, and not suitable for the stomach at all.

In this regard, Xu Chuan can only say that you really only deserve to eat burger sandwiches and fries.

.......

After politely declining all the students and assistants who came to recommend tutors, and publicly saying that they already had tutors, the following time was a lot quieter, and there was no longer an endless stream of people coming to talk to them.

After adjusting the pace of life and jet lag for a day or two, Xu Chuan almost completely adapted to the lifestyle here in Princeton, and received invitations from various clubs at Princeton University by the way.

It's worth mentioning that in Princeton, the various clubs that have been built around the entire campus are quite a beautiful cultural scene.

Princeton's 'pocket' university has just over 1,000 freshmen each year, but it has more than 300 student organizations, 38 sports clubs, and a dozen pastors and campus centers where students can pray.

These student organizations and clubs make up much of Princeton's campus culture, and they are hierarchical, many of which are highly xenophobic, or chains of contempt.

For example, a food club.

Princeton has 11 eating clubs, 5 of which are no-entry and 6 that require screening.

In contrast to fraternities, sororities, or other societies, the food club has its own selection process called the "bicker" process, in which students get to know each other in an academic "argument" with the members of the food club.

Obviously, the food clubs that need to be screened before they can enter, such as the Ivy League Food Club, have top students.

But don't simply think that this is a similar structure to the student union in China.

Here, the top club can provide student members with help and free guidance in studying abroad applications, career planning, academic exchanges, etc., and will also hold regular study abroad lectures and salons, and invite students from other famous universities such as Harvard and Yale and career elites to share valuable experience in study abroad application and job search and employment for members.

This is a platform for high-end social networking and DIY resource sharing, so it will also be heavily screened and filtered step by step.

Of course, these heavy screenings are completely non-existent rules for real top talents.

It's like the Ivy League Club, the top club in Princeton University, Xu Chuan hasn't applied for it in his life, and the other party took the initiative to send him an invitation.

In comparison, there is no comparison between the previous life and the fact that I went through the steps of application, traditional and ancient debate, etc., and there is a world of difference between the two.

It can only be said that geniuses or capable people are welcome everywhere.

.........

After dealing with invitations from clubs, student organizations, etc., Xu Chuan retreated back to his dormitory, ready to concentrate on completing the data calculations for the 'Proton Radius Mystery' problem.

But just then, he received a call from his mentor, Deligne.

Putting down the manuscript paper in his hand, Xu Chuan came to the Institute for Advanced Study in Princeton.

Most of the time, his two mentors, Deligne and Witten, are basically doing research at the graduate school, and as for the classes at Princeton University, if they are in a good mood or have a big class, they will go over once, and the rest of the time is basically handed over to their assistants or students.

This is normal for an elder of their level.

Knocking on the office door, Xu Chuan walked in, and in the office, an old man in long sleeves was sitting at a desk.

"Mentor."

Xu Chuan said hello, and Deligne glanced up and put down the ballpoint pen in his hand.

"How have you been adapting in the past two days? Have you adjusted for the jet lag or something? ”

Xu Chuan: "Thanks to the teacher's concern, it has been adjusted." ”

Deligne: "That's good, adapt to life here as soon as possible, and enter the state of study and research as soon as possible, Witten is still waiting for you." ”

Xu Chuan nodded: "I will do my best to speed up the improvement." ”

Hearing this, Deligne smiled and said: "Don't be so anxious, study and research should be combined with daily life, Princeton still has many interesting clubs and student organizations, such as rugby, football, ice skating, you can get in touch with these, after all, the body is the most important." ”

Deligne advises with a smile, he is not worried that the student in front of him is not working his studies.

Whether it was him, Witten, or other professors at Princeton, they all brought students from China.

In addition to the rest, in terms of diligence and hard work, there are no other students in Princeton who can compare with students from China.

Sometimes they hardly have any other recreational activities other than eating, sleeping, and studying.

Such a student cannot be said to be bad, but he lacks a little of the spirituality and communication necessary for academic pursuit.

And sometimes, it is often this spirituality and communication that can push a person further down the academic path.

It is impossible to engage in academic and research behind closed doors, and apart from Perelman's 'weirdo', there are almost no researchers who have made significant achievements behind closed doors.

Inspiration and sparks are born in communication and collision, and a person's thinking is always limited.

Therefore, Deligne hopes that Xu Chuan can go out more activities, make some friends, and maintain the absorption of external knowledge.

Xu Chuan naturally knew about this, and nodded in response.

While his approach to learning and research is somewhat similar to Perelman's ascetic approach, he has never denied the importance of interacting with his top peers.

"By the way, this is for you."

After a brief chat, Professor Deligne took out a piece of paper that looked like a certificate from the drawer, placed it on the table, and pushed it to Xu Chuan.

Xu Chuan picked up the paper from the table with some curiosity and glanced at it.

"Bursary Scholarship?"

Deligne nodded and said, "Well, when I went through the admission procedures for you before, I applied for a full prize for you by the way, and when you take it to the Academic Affairs Office, you can be exempted from tuition and accommodation fees, and you will also be given a living allowance of 100,000 meters, which can be used for daily life subsidies." ”

After a pause, Professor Deligne added: "Of course, with your grades, you can apply for it yourself." ”

Holding the scholarship in his hand, Xu Chuan thanked Professor Deligne.

Neither he nor Déligne cared about it, though.

Although Princeton's bursary award, which includes a bursary + scholarship + waiver of tuition and fees, is difficult to get, especially at the doctoral level, the competition is fierce.

After all, Princeton University tuition is ridiculously expensive.

Not to mention the doctoral level, the tuition fee for undergraduate students alone exceeds 50,000 meters per year, which is 30,000 and 50,000 per Chinese New Year's Eve.

In addition to tuition, there are accommodation, meals, other miscellaneous expenses, and so on.

In total, the tuition fees that need to be spent on studying alone every year are at least 780,000 meters, almost 500,000 y.

Ordinary families simply can't afford such high tuition fees.

And the full award can waive all tuition and fees, accommodation fees, and give you an additional living expenses, which will naturally be fought for by countless people.

However, the application for the full prize is also divided into people.

For Xu Chuan, he is qualified to serve as a full professor directly at Princeton, and can write applications and letters of recommendation to other students, and now he is admitted in the name of a doctoral student, a full award, as long as he applies, Princeton will inevitably pass, even if the review system is strict.

For a gifted teenager who can prove world-class mathematical conjectures at the age of eighteen, no matter which school he goes to, a scholarship or something, it is almost doomed.

Even if he doesn't want to, the school will be stuffed into his arms.

........

After dealing with these trivial chores, Xu Chuan settled down at Princeton University and began to concentrate on perfecting the calculation method of the 'proton radius riddle'.

If you are an ordinary doctoral student, after visiting a supervisor, you will definitely have teaching assistants, scientific research experiment assistants and other jobs.

Xu Chuan was no exception, Professor Deligne arranged for him to be a teaching assistant, but the time of the teaching assistant was not forced, and he was given priority to complete Professor Witten's requirements.

Deligne is not worried that this student will waste his mathematical knowledge, although the problem of the 'mystery of the proton radius' is in the field of physics, but because Xu Chuan's research is based on mathematics, it belongs to the study of mathematics in the final analysis.

The days passed like this, and in the blink of an eye, the time came to the beginning of July.

During this month, Xu Chuan not only perfected the calculation method of the "Proton Radius Puzzle" every day, but also studied other mathematical knowledge with Professor Deligne.

Focusing on the number theory and differential equations that Xu Chuan wanted to learn, the old professor would occasionally teach him some mathematics in algebraic geometry.

After all, Pope Grothendieck Sr., who studied algebraic geometry, algebraic geometry can be said to be a compulsory course.

After more than a month of study, Xu Chuan has a deeper understanding of his mathematics tutor.

There was nothing wrong with his choice.

Although this mentor has been a papal student all his life, it is an honor and a tragedy that cannot be escaped. But this old man's knowledge is really vast and boundless, giving people a sense of unfathomable depth with no end in sight.

In the past month, almost all the various questions he encountered in the process of studying number theory have been answered and inspired by this old man.

Xu Chuan was amazed by Professor Deligne's knowledge, and Professor Deligne was also surprised, even shocked, by Xu Chuan's talent.

In the past month, Xu Chuan mainly learned the knowledge of analytic number theory from him, and there was no hiding in front of him.

In the beginning, the young genius still had a lot of misunderstandings and ignorances about analytic number theory.

However, in just one month, he was able to use multiplicative number theory in analytic number theory to study the properties of the productive generation function with him and explore the problem of prime number distribution.

Although multiplicative number theory is only one part of analytic number theory, it still shocked him greatly.

A teenage genius who solved a world-class conjecture at the age of eighteen, his terrifying learning speed and mathematical talent were arguably the first people he had encountered in his decades at Princeton.

Even Tao Zhexuan, who is known as the 'Mozart of mathematics', when he was studying at Princeton, the mathematical talent he showed was a little bit lower than that of this teenager.
