In the evening, Ge Juntian took Jiang Shuiyuan and Zhang Jin to the hotel to meet Hui Chengze alone. For ordinary high school students, it is undoubtedly a huge honor to be able to sit down and chat face-to-face with academician-level figures. And Ge Juntian was able to take the two of them to see Hui Chengze, which also shows his great love for the two proud disciples.

When passing by Hui Qiongju's room, her door was not closed, and the three of them heard Hui Qiongju talking on the phone outside the house, describing everything they saw to someone vividly: "...... Liangshu, he really just glanced at it, and then memorized all those two questions! You know, when I first looked at it, I saw that messy picture, and I didn't know what the title was talking about. Then he closed his eyes and began to think, and in just a few seconds, he gave the solution to the first problem and the idea of the second question. You know, at that time, a lot of people didn't quite know what the first question meant. My first feeling at the time was that I had been in vain for so many years at Jingshi University!"

To say that Hui Qiongju has been in Jingshi University for so many years, it is not that she has never seen teachers and classmates with excellent memory, but it is the first one who is so exaggerated like Jiang Shuiyuan, especially when it is displayed in front of her so simply and rudely, which has brought her a huge impact and shock, making her eager to share her experience with her girlfriends.

Ge Juntian glanced at Jiang Shuiyuan, did not speak, and directly knocked on the door of Mr. Hui Chengze's room.

Hui Chengze was reviewing other people's academic papers in front of the computer, and when he heard the sound, he quickly got up and let the three of them into the room, and said to Jiang Shuiyuan and Zhang Jin with a smile: "You two little guys are good! I also pondered these two questions for a long time, but I didn't expect you to give the answer so quickly, no wonder your teacher Ge is so optimistic about you." ”

Zhang Jin stammered and replied: "I, I also spent a long time, the river and the river water source are the most powerful, and I can make it at a glance." ”

Jiang Shuiyuan waved his hand: "That's because I'm lucky, I happen to know the determination theorem of the four-point continuum." Otherwise, it wouldn't have been made so quickly. Speaking of which, I would like to thank Mr. Ge for his teaching, otherwise we wouldn't even be able to touch the four-point confluence problem. ”

Ge Juntian glanced at him again, meaning that even if you kid has a conscience, you can still remember the teacher's good at this time!

Hui Chengze laughed: "Xiao Jiang is right! If you don't know the four-point coherence theorem, it is indeed very difficult to solve the first problem. It feels like a tiger eating the sky - nowhere to eat. But what if you knew? What would have seemed like a tricky topic becomes a breeze. In fact, this is not only the case with mathematics, but also with all subjects, and even the whole life, which used to seem to be an insurmountable hurdle, but after a few years of rich knowledge and experience, it is not worth mentioning at all. Therefore, don't be discouraged when you encounter problems, and accumulate more knowledge and experience while you are young. ”

Jiang Shuiyuan and Zhang Jin nodded again and again when they heard this: Sure enough, academicians are academicians, and so many life philosophies can be derived from such a trivial matter!

Ge Juntian knew that Hui Chengze was using the topic to play, and took the opportunity to enlighten himself not to be entangled in the previous oath. The Hilbert problem can be solved slowly by accumulating knowledge, the key is to go to Jingshi University as soon as possible to study for graduate school, and by the way, get married!

Since Hui Chengze threw out the question, Ge Juntian couldn't help but answer, so he had to continue with the conversation: "The teacher has a point! But just like the inverse theorem exists in our mathematics, what the teacher just said sometimes the other way around, for example, running 800 meters and climbing the 10th floor when he was young is not a problem at all." When I get old, my muscles are sore, and even standing up and walking two steps has become a luxury. And the ones in our math. Middle school students all know that the sum of the internal angles of a triangle is equal to 180 degrees, but in the eyes of the great mathematicians, there is a problem, thinking that it may be greater than 180 degrees or less than 180 degrees, so they developed Lobachevsky geometry and Liman geometry. ”

Hui Chengze pointed at Ge Juntian and scolded: "You, you, you know that you are stubborn." Sooner or later you'll regret it!"

The atmosphere in the room was a little dreary for a while. Hui Chengze sighed slightly, then turned his head and asked Zhang Jin kindly: "Zhang Jin, have you been under a lot of pressure on schoolwork lately, what books are you reading after class?"

Zhang Jin rubbed the corner of his clothes and replied solemnly: "The pressure of class and homework is quite high, and I usually read some math materials given by Mr. Ge and Mr. Ge outside of class. ”

"Oh, what are you reading right now?"

"I'm looking at Introduction to Algebra. ”

"You like algebra?"

"No, I don't know. ”

Hui Chengze nodded: "That's right, algebra has many branches of disciplines such as linear algebra, group theory, domain theory, Lie group, Lie algebra, Kac-Moody algebra, ring theory, model theory, lattice theory, etc. Not to mention you, even a mathematician who specializes in algebra will find it difficult to know and like every sub-discipline. Let's change the question, which direction of mathematics do you prefer?"

Zhang Jin asked without answering: "What are the directions of mathematics and mathematics?"

"What are the directions of mathematics?" Hui Chengze counted with his fingers: "If you follow the division of the Ministry of Education, there are five second-level disciplines under the first-level discipline of mathematics, namely basic mathematics, computational mathematics, probability theory and mathematical statistics, applied mathematics, operations research and cybernetics. However, this classification is too general and slightly coarse, and the academic community generally refers to the national standard subject classification table, which is divided into 26 secondary disciplines under the first-level discipline of mathematics, such as history of mathematics, mathematical logic and mathematical foundations, number theory, algebra, algebraic geometry, geometry, topology, mathematical analysis, non-standard analysis, function theory, ordinary differential equations, partial differential equations, and dynamical systems, and there are more third-level disciplines below, with a total of no less than 150 kinds!"

"Ahh

"That's not much! For example, biology and economics have nearly 200 third-level disciplines, and that is the real giant!" Although Hui Chengze is engaged in mathematics, he is clear about the affairs of the academic world: "Nowadays, the knowledge is getting deeper and deeper, and the disciplines are becoming more and more detailed. Therefore, today, encyclopedic scientists like Mr. Sun Baixi, the father of the nation, who opened up politics, education, culture, science, engineering, and medicine, and spanned dozens of first-level disciplines, are basically impossible to appear again. No matter how powerful a genius is, he can only make first-class results in some professional directions of a few first-level disciplines, and it is impossible to be proficient in all aspects. ”

Ge Juntian glared at Jiang Shuiyuan and said: "Did you hear it? It's you! Look at how big your stall has been in the past few years, not to mention my math Olympiad, I also participated in singing and dancing, Chinese culture and difficulty, essay competitions, biology Olympiads, and became class president, president, and vice president of the student council. Look at what you can, why don't you go to heaven?"

Hui Chengze glared back at Ge Juntian dissatisfiedly: "People Xiaojiang participated in so many activities and can achieve such good results, which shows that people are energetic and have a wide range of hobbies." If you aim at Hilbert as soon as you come up, won't you be able to reach the heavens?"

"Yes, yes, yes. "Ge Juntian, how dare he have a half-sentence of stubbornness.

Hui Chengze saw that Ge Juntian had a good attitude in admitting his mistakes, so he continued: "It is precisely because the disciplines are becoming more and more detailed and people's energy is limited, that it is difficult for a school to ensure that it maintains the first position in the country in all fields of a certain discipline, even if it is a Jingshi University. Take mathematics as an example, the Department of Mathematics of Jingshi University is the first in the country in terms of historical origin and academic level, but it is not necessary to say that it is detailed to the specific secondary disciplines. For example, in probability theory, the most powerful should be Beiping Normal University, and you must know that the only academician of the Chinese Academy of Sciences in the direction of probability theory is in their school. Another example is fuzzy mathematics, the most powerful is an unknown ordinary university called Lingnan Institute of Technology. If you are interested in a certain branch of mathematics right now, you may wish to choose the best schools under the same conditions, so as to avoid many detours. If you haven't decided on a good direction, then choose a prestigious school, cultivate your academic heritage, and make a choice in the future. ”

Jiang Shuiyuan and Zhang Jin couldn't help but look at each other: it turns out that there are so many things to pay attention to in choosing a university in the college entrance examination, and they didn't know much about it before!

Hui Chengze saw the clue from the expressions of the two of them, shook his head and said: "A few years ago, I proposed to the Ministry of Education that a course should be opened at the high school level, and appropriately introduce the professional settings, subject classifications, main situations, and development prospects of China's colleges and universities, so that high school students can have an intuitive understanding of what courses to study in certain majors and what they can do in the future, and know what school they should go to if they want to develop in a certain direction in the future." Avoid being influenced by the social atmosphere, feel that it is good to study computer science and economics, and rush to apply for the computer department and business administration department, and only to find that it is far from your own interests when you go to university, regret it, and even suffer for a lifetime. Now it seems that the Ministry of Education is completely dismissive and indifferent to the words of this old man!"

Ge Juntian hurriedly said: "Teacher, don't worry, tomorrow I will make a suggestion to our Principal Lei and ask him to add this part of the content to the career planning course to ensure that it is implemented in Huai'an Mansion!"

Hui Chengze said: "This kind of thing should first consult your principal, if it can be increased, it will be increased, and if it can't be increased, even if the old man's belly is out of place." By the way, Zhang Jin, what university would you like to study in if possible?"

"I—Have I ever thought about it. Zhang Jin lowered his head and said.

Hui Chengze hadn't asked Jiang Shuiyuan what he thought, and Hui Qiongju, who had just entered the house after making the call, covered his coffin for him and said, "If Jiang Shuiyuan is going to study in the mathematics department of our Jingshi University, right?" )
