The matter of enrollment and enrollment was quickly settled.

Xu Chuan enrolled in NTU again, but this time as a doctoral student.

But apart from the change from a college student to a doctoral student, almost nothing else has changed.

The supervisor is still Chen Zhengping, the place where he lives is still the original single dormitory, the meals are still in the cafeteria, and the classes are held, oh, the classes have changed, from the undergraduate course to the doctoral course.

For the average undergraduate and doctoral student, college and Ph.D. are completely different experiences.

Because the nature of learning is completely different between the two.

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

Taking the Department of Physics of NTU as an example, the Department of Physics of NTU not only needs to learn the basic knowledge of physics, but also takes mathematics courses, chemistry courses, a small number of computer courses, and professional courses involve most of the geoscience-related disciplines such as geological engineering, geophysics, geochemistry, paleontology, tectonics, and mineral deposits.

The purpose is to give students a lot of knowledge in the field of professional popularization during the undergraduate period, which is conducive to students to choose their favorite direction in the future, and at the same time, it can be regarded as a good foundation, so that they will not know nothing about the field of their research direction in the future.

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

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

So the difference between undergraduate and doctoral is still very big, one learns, the other creates.

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

In fact, he did not follow the curriculum of ordinary undergraduates, but should have taken the route of a master's student.

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

As for the doctoral level, the general doctoral program is selected by the supervisor and the student together, and is linked to the supervisor and the student's own research project.

But what he studied during his doctoral stage, Chen Zhengping didn't ask a word, and went straight to the stocking.

In Chen Zhengping's opinion, anyway, his disciple is about to go to Princeton, does it matter what he studies during the doctoral stage of NTU? It doesn't matter at all.

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

He went to Princeton to study the mathematics he needed in depth, although he did not have a complete specific plan, but the general direction was there, such as turbulence, smooth flow, chaos, analysis, complex functions, algebra, fractals........

"Hiss~"

After calculating it, Xu Chuan suddenly gasped, it seemed that there were a lot of things he had to learn.

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

For example, turbulence is a well-known problem in mathematics, and no mathematician has ever been able to build a mathematical model for any turbulence.

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

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

Pick out any of these branches, and it is enough for a mathematician to study for a lifetime.

Although he has enough confidence in his science talent, Xu Chuan will also begin to doubt his life a little.

Can he really learn so much?

It's a tough challenge, but how is it so exciting?

.........

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

After the Morningstar Math Prize was presented at the end of this month, he was going to Princeton, and when he got there, it would be very troublesome to go home again, and he had to toss back and forth for at least three or four days at a time.

Xu Chuan estimated that it might be the end of the year when he went over there and came back.

So while he is still in China, go back to accompany his family, and see if there is anyone he needs help at home.

He now has six or seven million in cash, most of which comes from various bonuses to prove mathematical conjectures, and a small part comes from the scholarships and grants promised by the school before.

In addition, there is a reward for publishing papers in top journals.

In fact, there are a lot of this part, such as the weakened form proof of the Weyl-Berry conjecture, the reward for SCI papers after the publication of the paper is 260,000, and the proof of the Weyl-Berry conjecture is as high as 590,000.

The rewards for these papers are separate from the bonuses given to prove the conjecture, and last year he published several top journal papers, and the total number of papers added up to more than one million prizes.

However, this kind of thing of getting school bonuses by brushing sci papers is just a freak for him.

As for the Southern Conference, it won't mind, and the Southern University will only say, please do more of this kind of thing, isn't it a bonus, I have it.

For a university, the more SCI papers in top journals, the better, which is related to the evaluation of the school grade, as well as the attraction of talents, enrollment, the amount of scientific research funds and a series of things.

Just like Xu Chuan proved the Weyl-Berry conjecture, the amount of NTU's scientific research funding can increase by at least 0.5 percentage points next year.

Don't underestimate this 0.5 percentage point, it looks very little, but on the basis of 100 million, the amount of funds raised starts at the level of millions.

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

On this basis, 0.5 percent is 39 million, close to 40 million.

What university doesn't want more than 40 million in scientific research funding?

This is still relatively small, and if the Yugoslav Conference strives for it, the increased scientific research funds may be able to exceed 100 million.

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

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

In particular, the proof paper of the Weyl-Berry conjecture is a world-class mathematical conjecture.

Who would dare to say that the mathematics department of NTU is rubbish if it can cultivate mathematical talents who can prove world-class conjectures?

.........

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

Compared with the rapid changes in big cities, time seems to stand still in this small mountain village, and it is still quiet here despite the development outside.

Along the cement road that had been repaired a few years ago, Xu Chuan dragged his suitcase all the way to the depths of the village, occasionally encountering a few village elders busy in the fields on the way, and he also greeted him with a smile.

Soon, a house under construction came into view of Xu Chuan.

"Mom, I'm back."

Dragging his luggage, Xu Chuan shouted to his mother, who was squatting by the well in the new house to choose vegetables.

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

"Chuan'er is back."

Seeing the familiar figure, Xu Mu stood up happily, wiped her wet hands on her clothes and pants, and walked over quickly to take the suitcase from Xu Chuan's hands.

Xu Chuan said with a smile: "Well, come back from vacation to rest for a few days, and by the way, see how the new home is built." ”

"If you have a holiday, you will stay for a few more days, the house is still early, and the exterior wall is still being built not long after the foundation has been laid, and it is estimated that it will not be completed until October."

Xu Mu happily dragged the suitcase towards the old house, his family did not push the old house to the original foundation to rebuild, but re-selected a homestead in the village, the old house is still left without pushing, this will Xu Chuan come back but there is still a place to live.

........

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

At dinner, Xu Chuan asked his father.

Xu Jianguo thought that Xu Chuan needed money, so he said: "Plus the one you stayed behind last time, there are currently more than 1.6 million yuan in the family, do you need money?" How much do you want, let your mother go to the bank tomorrow and transfer it to you. ”

Seeing that his father misunderstood what he meant, Xu Chuan hurriedly said: "No, I don't need it, I just ask if there is a shortage of money to build a house at home, and I still have five or six million on my side if I lack money, so you don't have to borrow it from others." ”

"Where did you get that much money? Didn't do anything illegal, did you? You can't do anything that violates the law, Chuan'er. Hearing that Xu Chuan still had millions in his hand, Xu Jianguo was stunned for a moment and hurriedly asked.

Xu Chuan shook his head with a smile and said: "I'm the kind of person who will do illegal things, I solved a problem for the country and the school some time ago, and the money is rewarded by the school and the state, and my early graduation this time is also related to the problem solved." ”

"What problem is worth millions?" Xu Jianguo asked stunned.

Xu Chuan smiled and asked, "In March, did any leaders from the county come to our house?" ”

Xu Jianguo recalled for a moment and said: "Yes, the county officials did come to our house, condoled us, and rewarded 100,000 yuan, saying that it was your ......., huh?" Is that the time? At that time, the senior county official said that you have solved a world-class problem and contributed to the country. ”

After recalling, he looked at his son in hindsight.

Xu Chuan nodded and said, "That's right, the money on my side is basically rewarded by the state, don't worry, Dad, it's impossible for me to do anything illegal." ”

Xu Jianguo breathed a sigh of relief and said, "It's good that you haven't done anything illegal." ”

After a pause, he continued: "You keep the money on your body, you don't need it at home, and 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, you keep the money on your card, you still have money at home, it's enough, you are out by yourself, there are many places to use money, and you will need money to buy a house and marry a wife in the future." ”

Xu Chuan: "Listen to me, Dad, what about these two million, of which 1.5 million are used to repair a new house, I know this is left to me, and you also said that you will marry a wife or something, so try to choose some materials for subsequent decoration." ”

"There is another 500,000 yuan, which is reserved for the village, and this money is in your hands, go and 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, and now that we have the ability, we still have to give feedback, and we can also block some rumors."

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

It doesn't take two or three million to build a new house, and one million is enough to build a very beautiful villa in the countryside, but he asked his father to use good materials to decorate or something in the name of the new house, so that he could get by.

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

His family has received a lot of help from the village, and when he was admitted to Xingcheng High School, most of the families in the village gave him super red envelopes when they held a wedding banquet to help him go to school.

Including after the college entrance examination last year, the village also tried to reward him with a sum of money, although it was not much, but it must be remembered.

So Xu Chuan wants to help the village repair the pond dam that stores water, this reason is very right, he estimates that his father will not refuse, after all, every household in the village still has farming.

In addition, this is also to save face for his own family, to save face for his father, to show others that reading can get ahead, and to remove the rumors of a small number of people.

After all, where there are people, there are rivers and lakes, although most of the people are very good, but when the forest is big, there are always a few Du Juan.

Some people always like to say that they may not be able to make money if they study, and his nephew can open a company without studying after graduating from junior high school, and make hundreds of thousands of dollars a year, so that college students can help him work or something, and gossip behind his back.

This time, Xu Chuan completely blocked these people's mouths.
