Student status and admission matters were settled quickly.
Xu Chuan enrolled in Nanjing University again, but this time he entered the school as a doctoral candidate.
But apart from changing from a college student to a doctoral student, almost nothing else has changed.
The instructor is still Chen Zhengping, the place he lives in is still the original single dormitory, the meals are still in the cafeteria, and the classes are still there. Oh, the classes have changed, from undergraduate courses to doctoral courses.
For ordinary undergraduates and doctoral students, university and doctoral degrees are completely different experiences.
Because the nature of learning between the two is completely different.
In terms of learning content, the undergraduate content focuses on basic knowledge and the breadth of learning.
Take the Physics Department of NTU as an example. The Physics Department of NTU requires not only learning basic knowledge of physics, but also mathematics courses, chemistry courses, and a small number of computer courses. At the same time, professional courses involve geological engineering, geophysics, geochemistry, paleontology, and tectonics.
Science, mineral deposit science and most other geoscience related disciplines.
The purpose is to provide students with a large amount of knowledge in major-related fields during their 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 know anything about the field of their own research direction in the future.
The courses during the doctoral period are very targeted, and the selection 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 essential. Using scientific research experiments to create knowledge is the learning content of doctoral students.
So the difference between a bachelor's degree and a doctorate is still very big, one is learning and the other is creating.
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 ordinary undergraduate course, but should have taken the route of a master's degree.
When he first entered school, Chen Zhengping discussed the direction of his undergraduate study with him. At that time, he often went to class. However, after the weak Weyl-Berry conjecture was proved, he rarely went to class. Instead, he often went to the library.
As for the doctoral stage, generally doctoral courses are selected by the tutor and the student together, and are linked to the tutor's and the student's own scientific research projects.
But Chen Zhengping didn't even ask him what he was studying during his Ph.D., and he just gave up on it completely.
In Chen Zhengping's view, since his disciple is going to Princeton soon, does it matter what he studies during his doctoral studies at NTU? It doesn't matter at all.
Xu Chuan didn't care about these things. He had a sufficient understanding of his life plan.
Go to Princeton to learn the necessary mathematical knowledge in depth. Although he has not yet completed the specific planning, he has a general direction, such as turbulence, smooth flow, chaos, analysis, complex functions, algebra, and fractals that he is most concerned about.
........
"Hiss~"
After doing the math, Xu Chuan suddenly took a breath. He seemed to have a lot to learn.
Each of these names is a very large branch of mathematics, and they are all very difficult.
For example, turbulence is a well-known problem in mathematics. So far, no mathematician has been able to establish a mathematical model for any turbulence.
For example, smoothness is popular. 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 even more things under this very large branch, such as algebraic geometry, algebraic number theory, Clifford algebra, Lie algebra, Boolean algebra, etc.
Just picking any one of these branches is enough for a mathematician to study for a lifetime.
Although he was confident enough in his talent in science, Xu Chuan also began to doubt life a little.
Can he really learn so many things after studying?
This is indeed a difficult challenge, but why is it so exciting?
.........
After re-enrolling in school, Xu Chuan asked for a leave of absence from his tutor Chen Zhengping and returned 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 home. It will take at least three or four days to go back and forth at a time.
Xu Chuan estimated that after going there, he might come back at the end of the year.
So while he is still in the country, he goes back to spend time with his family and see if there is anyone at home who needs help.
He currently has six to seven million in cash, most of which comes from various prizes for proving mathematical conjectures, and a small part of which comes from scholarships and grants promised by the school.
In addition, there are rewards from the school for publishing papers in top journals.
There are actually quite a lot of this part. For example, the weakened form of the Weyl-berry conjecture proves that the SCI paper reward after the paper is published 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 for proving conjectures. Last year, he published several papers in top journals, and the total bonuses he received for these papers amounted to more than one million yuan.
But this kind of thing about getting school bonuses by writing SCI papers is just a weirdo like him.
As for whether Nanda will mind, Nanda will only say, please do more of this kind of thing. Isn’t it just a bonus? I have plenty.
For a university, the more SCI papers in top journals, the better. This is related to the evaluation of the school's grade, as well as the attraction of talents, enrollment, the amount of scientific research funds, and a series of other things.
Just like after Xu Chuan proved the Weyl-Berry conjecture, the amount of scientific research funds at NTU will increase by at least 0.5 percentage points next year.
Don't underestimate this 0.5 percentage point, it may seem like a small amount, but when put on a basis of hundreds of millions, the amount of funds increased starts from millions.
NTU’s total scientific research funding this year is 7.8 billion.
Based on this number, 0.5 percent is 39 million, which is close to 40 million.
Which university wouldn’t want 40 million more scientific research funds?
This is still a relatively small amount. If Nanjing University fights for it, the increased scientific research funds may exceed 100 million.
In comparison, the little money awarded to Xu Chuan was really insignificant.
In addition to scientific research funds, there are also various factors such as the school's influence, honors, school academic capabilities, etc.
Especially the proof papers like the Weyl-berry conjecture, which is a world-class mathematical conjecture.
Who dares to say that NTU’s mathematics department is rubbish if it can produce 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 rapid changes in big cities, time seems to have stood still in this small mountain village. No matter what happens outside, it remains quiet here.
Along the cement road that had been built a few years ago, Xu Chuan dragged his suitcase and walked deep into the village. On the way, he occasionally encountered a few village elders busy in the fields, and he also said hello with a smile.
Soon, a house under construction came into Xu Chuan's sight.
"Mom, I'm back."
Dragging his luggage, Xu Chuan called out to his mother who was squatting by the well in her new house choosing vegetables.
Hearing the sound, Xu's mother turned her head and looked, 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 clothes, and quickly came over and took the suitcase from Xu Chuan's hand.
Xu Chuan smiled and said, "Well, I'm coming back for a few days to rest after the holiday, and take a look at how the construction of the new home is going."
"I'll stay there for a few more days if I have a vacation. It's still early for the house. The foundation has just been laid and the exterior walls are still being built. I estimate it won't be completed until October for people to move in."
Xu's mother happily dragged her suitcase towards the old house. This time, her family did not push the old house and rebuild it on the original foundation. Instead, they chose a new homestead in the village.
The old house is still there and has not been pushed forward. When Xu Chuan comes back, he will have a place to live.
........
"Dad, do we 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, the family currently has a total of more than 1.6 million. Do you need money? How much? Ask your mother to transfer it to the bank tomorrow.
you."
Seeing that his father had misunderstood what he meant, Xu Chuan said quickly: "No, I don't need it. I just asked if the family is still short of money to build a house. If I am short of money, I still have five or six million here. You don't have to go and fight with me."
Borrow it from someone else.”
"Where did you get so much money? You didn't do anything illegal, right? You can't do illegal things, Chuan'er." Hearing that Xu Chuan still had several million in his hand, Xu Jianguo was stunned for a moment and asked quickly.
Xu Chuan shook his head dumbfounded and said: "I am the kind of person who will do illegal things. I solved a problem for the country and the school some time ago. All the money was awarded by the school and the country. This time I will advance
Graduation is also related to the problems solved."
"What question is worth millions?" Xu Jianguo asked in confusion.
Xu Chuan smiled and asked, "Did any leaders from the county come to our house in March?"
Xu Jianguo recalled for a while and said: "Yes, the senior county official did come to our home, expressed condolences to us, and rewarded us with 100,000 yuan, saying it was you..., eh? Was that that time? That time
The senior county official said that you solved a world-class problem and made a contribution to the country."
After recalling it, he belatedly looked at his son.
Xu Chuan nodded and said: "Yes, the money I have here is basically from the national reward. Don't worry, Dad, I can't do anything illegal."
Xu Jianguo breathed a sigh of relief and said, "It's fine that I didn't do anything illegal."
After a pause, he continued: "Keep the money you have for yourself. Your family doesn't need it. The money you left last time was enough to build a new house."
Xu Chuan thought for a while and said: "In this case, I will transfer another two million to my mother's card..."
Before he could finish his words, he was interrupted by his father: "No, keep the money on your card for yourself. There is still money at home, which is enough. You are out on your own and there are many places where you need to use money. You will buy a house in the future."
Getting a wife costs money for everything.”
Xu Chuan: "Listen to me, Dad, there are two million, of which 1.5 million is used to build a new house. I know this is left for me. You also said about marrying a wife, so the materials for subsequent decoration will be used."
Try to choose something better."
"There are also five hundred thousand left for the village. You will be in charge of this money to 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 also stop some rumors."
Xu Chuan made two excuses, otherwise he knew that his father would never accept the money again.
It doesn't take two or three million to build a new house. One million is enough to build a beautiful villa in the countryside. However, in the name of the new house being given to him, he asked his father to use good materials to decorate it, so that he could get by.
Already.
As for giving back to the village, there is nothing to say about that.
His family received a lot of help from the village. When he was admitted to Star City High School, most families in the village gave him extra-large red envelopes during the wedding banquet to support his education.
Including after last year's college entrance examination, the village also found ways to reward him with a sum of money. Although it was not much, it must be remembered.
So Xu Chuan wanted to help the village build ponds and dams for water storage. This reason was very valid. He guessed that his father would not refuse. After all, every household in the village still farmed.
In addition, this is also to support my family and my father, show others that studying can help me get ahead, and get rid of the gossip of a few people.
After all, wherever there are people, there are rivers and lakes. Although most people are nice, there are always a few Du Juans in the forest.
Some people always like to say that you may not be able to make money even if you study. His nephew graduated from junior high school and started a company that earned hundreds of thousands a year without studying. He asked college students to work for him 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 grinding for five or six hours, I finally finished the second one. Let's just update it again tomorrow. Have a good rest and resume the update the day after tomorrow.
