Great Country Academician

The matter of student status and enrollment was settled quickly.

Xu Chuan entered Nanjing University again, but this time he entered the school as a doctoral student.

But other than changing from a college student to a doctoral student, little else has changed.

The tutor is still Chen Zhengping, the place to live is still the original single dormitory, the meal is still in the cafeteria, and the class, oh, the class has changed, from undergraduate courses to doctoral courses.

For ordinary undergraduates and PhD students, university and PhD are completely different experiences.

Because the nature of the two learning is completely different.

In terms of learning content, the undergraduate content focuses on basic knowledge and the breadth of learning.

Take the Department of Physics of Nantah University as an example. The Department of Physics of Nantah University not only needs to learn basic knowledge of physics, but also to learn mathematics courses, chemistry courses, and a small amount of computer courses. At the same time, professional courses involve geological engineering, geophysics, geochemistry, paleontology, and structure Geosciences, mineral deposits and most other geoscience-related disciplines.

The purpose is to give students a lot of popularization of professional-related field knowledge during the undergraduate period, which will help students choose their favorite direction in the future, and at the same time lay a solid foundation so that they will not be ignorant of their own research fields in the future.

The courses during the doctoral period are very targeted, and the choice of courses is basically determined by the tutor. It is mainly to supplement the knowledge related to the project.

For a doctoral student, scientific research is indispensable. Using scientific research experiments to create knowledge is the learning content of doctoral students.

So there is still a big difference between a bachelor's degree and a Ph.D., one for learning and one for creation.

However, for Xu Chuan, there seems to be no difference between the undergraduate stage and the doctoral stage.

In fact, his undergraduate course did not follow the course of ordinary undergraduate students, and he should take the route of master's degree students.

When he first entered school, Chen Zhengping discussed with him the direction of undergraduate study. At that time, he often went to class, but after the weak Weyl-Berry conjecture was proved, he seldom went to class, but often ran to the library.

As for the doctoral stage, the general doctoral courses are selected through consultation between the tutor and the students, and are linked to the research projects of the tutor and the students themselves.

But Chen Zhengping didn't even ask him what he was studying at the doctoral stage, and he just gave it away completely.

In Chen Zhengping's opinion, since his student is going to Princeton soon, is it important what he studies during his Ph.D. at Nantah University? It doesn't matter at all.

Xu Chuan didn't care about these things either, he had a good understanding of his life plan.

Go to Princeton to learn the required mathematical knowledge in depth. Although he has not yet completed the specific plan, he has a general direction, such as turbulence, smooth flow, chaos, analysis, complex variable function, algebra, fractal, which he is most concerned about. .

"Hiss~"

After thinking about it, Xu Chuan suddenly took a deep breath. It seems that he has a lot to learn.

Each of these names is a very large branch of mathematics, and all of them are very difficult.

For example, turbulent flow is a well-known difficult problem in the field of mathematics. So far, no mathematician has been able to establish a mathematical model for any turbulent flow.

For example, smoothness is popular, and this branch directly points to one of the seven millennium problems in mathematics, "the existence and smoothness of solutions to NS equations".

Another example is algebra, there are more things under this super branch, such as algebraic geometry, algebraic number theory, Clifford algebra, Lie algebra, Boolean algebra and so on.

Picking out any one of these branches is enough for a mathematician to study and study for a lifetime.

Although he has enough confidence in his talent in science, Xu Chuan also began to doubt his life at this time.

Can he really finish learning so many things?

This is indeed a very difficult challenge, but why is it so exciting?

After re-enrolling, Xu Chuan asked his tutor Chen Zhengping for a leave of absence and went back to his hometown.

After the Morning Star Mathematics Prize is awarded at the end of this month, he will go to Princeton. Once there, it will be very troublesome to go back home. It will take at least three or four days to go back and forth.

Xu Chuan reckoned that it might be the end of the year when he came back after going there.

So while he was still in the country, he went back to spend time with his family, and by the way, check if there was anything he needed help at home.

He currently has six or seven million in cash, most of which come from various bonuses for proving mathematical conjectures, and a small part of it comes from the scholarships and bursaries promised by the school.

In addition, it is the reward of the school for publishing papers in TOP journals.

This part is actually quite a lot. For example, the weakened form proof of the Weyl-Berry conjecture, after the paper is published, the SCI paper reward is 260,000 yuan, and the proof of the Weyl-Berry conjecture is as high as 590,000 yuan.

The rewards for these papers are separate from the rewards for proving conjectures. Last year, he published several papers in top journals, and the total rewards for all these papers were more than one million.

But this kind of thing of getting school bonuses by writing SCI papers is only a freak like him.

As for whether NTU would mind, NTU would only say, please do more of this kind of thing, isn't it just a bonus, I have plenty of it.

For a university, the more SCI papers in top journals, the better. This is related to the assessment of the school's level, as well as a series of things such as attracting talents, recruiting students, and the amount of scientific research funds.

Just like Xu Chuan proved the Weyl-Berry conjecture, the amount of scientific research funds in NTU will increase by at least 0.5% next year.

Don't underestimate the 0.5% point, it looks like a small amount, but if you put it on a base of 100 million, the amount of increased funds will start at the million level.

NTU’s total scientific research funding this year is 7.8 billion.

Calculated according to this number, 0.5 percent is 39 million, which is close to 40 million.

Forty million more scientific research funds, which university doesn't want it?

This is still relatively small. If the South University Congress fights for it, the increased scientific research funds may exceed 100 million.

In comparison, the little money rewarded to Xu Chuan was really insignificant.

In addition to scientific research funds, there are also various factors such as the influence of the school, honor, and academic ability of the school.

Especially proof papers like the Weyl-Berry conjecture, which is a world-class mathematical conjecture.

Who dares to say that Nantah's mathematics department is rubbish when it can cultivate mathematical talents who can prove world-class conjectures?

After several hours of high-speed rail and taxi rides, Xu Chuan returned to his hometown smoothly.

Compared with the ever-changing big cities, time seems to stand still in this small mountain village, and it is still quiet here as the outside world develops.

Along the concrete road repaired in the past few years, Xu Chuan dragged his suitcase and walked all the way to the depths of the village. On the way, he occasionally met a few village elders busy in the fields, and he greeted them with a smile.

Soon, a house under construction came into Xu Chuan's eyes.

"Mom, I'm back."

Dragging his luggage, Xu Chuan called out to his mother who was squatting by the well of the new house to choose vegetables.

Hearing the sound, Mother Xu turned her head to look, and then stood up in surprise.

"Chuan'er is back."

Seeing the familiar figure, Xu's mother stood up happily, wiped her wet hands on her underwear, and hurried over to take the suitcase from Xu Chuan's hands.

Xu Chuan smiled and said, "Well, come back from the holiday and rest for a few days, and take a look at how the new home is being built."

"If you have holidays, you can stay for a few more days. The house is still early, and the exterior walls are still being built not long after the foundation is laid. It is estimated that it will not be completed until October."

Xu's mother dragged her suitcase happily and walked towards the old house. This time, his family did not push the old house to rebuild on the original foundation, but chose a new homestead in the village. The old house is still in place, but when Xu Chuan comes back, he still has a place to live.

"Dad, do you still need money to build a house at home?"

During dinner, Xu Chuan asked his father.

Xu Jianguo thought that Xu Chuan needed money, so he said, "Including what you left last time, there is a total of more than 1.6 million in the family. Do you need money? How much do you want? Let your mother go to the bank to transfer it to you tomorrow." You."

Seeing that his father misunderstood what he meant, Xu Chuan quickly said: "No, I don't need it, I just ask if there is any money needed to build a house at home, and I still have five or six million yuan here, so you don't have to go and talk to me." Borrowed by others."

"Where did you get so much money? You didn't do anything illegal, did you? You can't do illegal things, Chuan'er." Hearing that Xu Chuan still had several million in his hand, Xu Jianguo froze for a moment, and asked quickly.

Xu Chuan shook his head dumbfounded, and said, "I'm the kind of person who would do illegal things. I solved a difficult problem for the country and the school some time ago. The money was rewarded by the school and the country. Graduation also has to do with the problems it solves.”

"What question can be worth millions?" Xu Jianguo asked in a daze.

Xu Chuan smiled and asked, "Did any leaders from the county visit our house in March?"

Xu Jianguo recalled it for a while, and said: "Yes, the county official did come to our house, expressed condolences to us, and rewarded us with 100,000 yuan, saying that it was you..., huh? Is that the time? That time the county official said you solved a problem. A world-class problem and a contribution to the country."

After recalling, he belatedly looked at his son.

Xu Chuan nodded, and said, "That's right, the money on my side is basically from that national reward. Don't worry, Dad, I can't do anything illegal."

Xu Jianguo breathed a sigh of relief and said, "It's good that I didn't do anything illegal."

After a pause, he continued: "You keep the money on your body for yourself. The family doesn't need it. The money you left last time is enough to build a new house."

Xu Chuan thought for a while and said, "In this way, I will transfer another two million to my mother's card."

Before he finished speaking, he was interrupted by his father: "No, keep the money on your card for yourself, and you still have money at home. It is enough. You are away by yourself. There are many places where you need money. You will buy a house in the future." Marrying a wife requires money for everything.”

Xu Chuan: "Listen, Dad, what about the two million yuan, of which 1.5 million is used to repair the new house, I know it is reserved for me, and you also said about marrying a wife, so the materials used for subsequent decoration Try to choose something better."

"There is another 500,000 yuan left for the village. You will be in charge of this money. Go communicate with the village and repair the large and small ponds in the village."

"After all, the village has helped our family so much over the years. Now that we have the ability, we still need to give feedback. In addition, we can stop some gossip."

Xu Chuan made two excuses, otherwise he knew that his father would definitely not accept the money again.

It doesn't take two or three million to build a new house, and one million is enough to build a beautiful villa in the countryside. However, he asked his father to use good materials to decorate the new house in the name of being for him, so that he can live a happy life. up.

As for giving back to the village, there is nothing to say about this.

His family received a lot of help from the village. When he was admitted to Xingcheng High School, most of the village's households gave extra-standard red envelopes at the wedding banquet to help him go to school.

Including after the college entrance examination last year, the village also found a way to reward him with a sum of money. Although it is not much, it must be kept in mind.

So Xu Chuan wanted to help the village repair ponds and dams for water storage. The reason was very good, and he reckoned that his father would not refuse, after all, every household in the village still farms.

In addition, this is also to save face for my family, to save face for my father, to show others that I can get ahead in reading, and to get rid of the gossip of a small number of people.

After all, where there are people, there are rivers and lakes. Although most of the people are good, there are always a few cuckoos in the forest.

Some people always like to say that even if you study, you may not be able to make money. His nephew graduated from junior high school and can start a company without studying. The annual income is hundreds of thousands, so college students come to help him work and gossip behind his back.

This time Xu Chuan completely blocked the mouths of these people.

Ps: The state is average, and I can’t concentrate. After five or six hours of grinding, I finally finished the second one. Let’s update it for another day tomorrow, take a good rest, and resume the update the day after tomorrow.
