The next day, after Yang Rui's morning self-study, he took a small class class of math master Jia Wanli.

There are only about 20 people in the small class, so naturally there is no time to gossip and read poetry collections. In fact, those who can participate in small class sizes cherish this opportunity, because classes such as English and mathematics are now divided into classes.

In the previous year, if you have a grade A, you will be placed in a small class of A, if you have a grade of B, you will be placed in a small class of B, and if you fail, you will have to repeat the course during the holidays or in the new semester.

However, with the exception of English, most students can get a grade of C or above, but it is still extremely difficult to get into a small class of A.

In a small class like A, the teaching difficulty of a big bull like Jia Wanli is also extremely high.

However, Yang Rui thinks it's very good, because Jia Wanli is not really infinitely more difficult, he just narrows the area of learning, so that his students can focus more on learning part of the knowledge.

In Yang Rui's view, this is the best choice, even for students who specialize in mathematics, it is impossible to learn every corner of mathematics, and those geniuses who win the Fields Medal are impossible.

For biology students, it is even more important to narrow down their learning, not to delve into infinite mathematics in a limited amount of time, and to understand what they need to know in detail is quite remarkable.

When you think about the difficulty of high school math, countless people are left behind, let alone the difficulty of advanced math.

Yang Rui is not ready to be a mathematician, so he doesn't need to spend all his time on mathematics, at this time, the role of a big bull like Jia Wanli is reflected.

At the very least, he knows how to narrow down his studies.

In the process of narrowing the learning surface, whether a point is narrowed or not depends on whether it is currently useful for biological research, and whether it will be useful for the study of biological mathematics in the future.

In the era when the syllabus was not yet complete, only Jia Wanli's first-class bull dared to take the initiative to narrow the learning surface, help students save time and improve overall efficiency.

Yang Rui listened very seriously.

By the end of the 90s, such opportunities were scarce, and some prestigious foreign universities, especially expensive private universities, could still afford such educational pressures, but the language and economic problems encountered by Chinese students abroad were far more serious than those at home.

Moreover, domestic university professors will now be more responsible.

Professor Jia Wanli corrects homework every week, regularly answers questions in the office, and occasionally holds free small classes in the office when students have a lot of questions.

Its efficiency is also extremely high, at least many times higher than Yang Rui's self-study.

In the past year, Yang Rui has greatly improved in mathematics, coupled with the accumulation of the repetition period, Yang Rui rarely encountered difficulties when he checked the biological research around the 90s.

Even if you really win the Nobel Prize, you don't dare to say that you are omniscient and omnipotent, and even a mathematician who has won a Fields Medal should consult other professors who have not won a Fields Medal.

When the bell rang for the end of class, Professor Jia Wanli stopped the pen in his hand and said, "That's all for today's class, students who have questions can come to my office on Wednesday." ”

Although he spent a long time on teaching, Jia Wanli still paid attention to the method and efficiency, and the students who needed it were more than enough to ask questions or something at any time, such as math.

There was a squeak of pushing desks, chairs and benches in the small classroom, and the students who had been in class put away their books tiredly, and looked up again, Professor Jia Wanli did not leave the classroom directly as usual, but took the initiative to come to Yang Rui and said with a smile: "Yang Rui, I heard that you have published another "Nature"?"

Yang Rui raised his head in surprise and said, "You know everything?"

"How can I not know, it has been spread all over the school, and a "cell" may have an accidental component, plus "nature", it is an undoubted talent. I heard that it is still a long article"

Yes, published under articles. "In several columns of the journal Nature, only under the article column, there are more than five pages of long articles, and scholars know it.

Jia Wanli nodded happily and said with a smile: "Look at your motivation to learn mathematics, you know that you are very thoughtful, continue to work hard, I support you to expand the laboratory." ”

He went around and learned the news that Yang Rui was going to expand the laboratory.

Yang Rui said cautiously: "Don't you think I'm a bit of a resource crowd?"

"Just kidding! You're trying to get resources for the school. ......Jia Wanli saw that there were other students in the classroom with their ears pricked up, lowered their voices, and said briefly: "You won the award, I don't know how much honor you want to fight for the school, the school doesn't give it to you, and the superiors will also allocate it to you." ”

Yang Ruixi smiled and said, "If you say that, I will be much more relieved." ”

"What do you have to worry about, it's someone else to worry about. Jia Wanli saw the figure outside the window flashing, Nunu mouthed, and said, "Look at people to be accurate." ”

Yang Rui inexplicably got a reminder, and inexplicably sent Professor Jia Wanli away, but he was surrounded by his classmates.

"Yang Rui, you have released "Nature" again?"

"What is Nature?"

“《nature》！”

"What's that?"

They are both second-year students at Peking University, but the students' insights are very different. In the ten years before university, middle school students in big cities such as Bei, Beijing, and Shanghai were exposed to more things than middle school students in the big ravines. After entering Peking University, there are students who study in the classroom, students who study in the library, students who study in school, and those who are not at ease to study.

However, with Yang Rui as a lesson from the past, the reputation of "Nature" has been played.

Yang Rui replied casually, and the rest of the questions were picked up by the students next to him, and after a while, the students who stayed in the classroom chatted together.

Yang Rui smiled, packed his schoolbag, and went out on one shoulder, he still had to go to the laboratory in the afternoon, and there was not much time for lunch.

At the door, a black shadow who had been wandering for an unknown amount of time saw Yang Rui, walked over quickly, stopped Yang Rui, and said with a smile: "Hello Yang Rui, do you have time to chat?"

The person who came was about 30 years old, with thick and dense eyebrows, big and bright eyes, and at first glance, it was the so-called thick eyebrows and big eyes.

"What's the matter?" Yang Rui stopped.

"Yang Rui. The person rubbed his hands, came to Yang Rui a little embarrassed, hesitated for a moment, and almost just when Yang Rui thought he was going to confess, this one opened his mouth and said, "I'm here to apologize." ”

"Why?"

"I'm here to apologize for my father, my father is Pang Xianzhen you met yesterday, my name is Pang Du, and I am his son. ”

"Are you Principal Pang's son?" Yang Rui somewhat understood.

"Yes, I am the son of Principal Pang and currently work in the school's academic affairs office. Pang Twilight laughed very shyly and said: "I'm different from my father, my father is a strong person, I have been more controlled by him since I was a child, but I am weaker, at the beginning, my father supported Richard, I was actually against it, but I am soft-spoken, I can't do anything......"

"The past is over. Yang Rui waved his hand and said, "There's no need to talk about the past." ”

"To say, to say. I apologize to you on behalf of my dad. My dad, I'm a little confused......" Pang Dusk said, a little verbose, but people couldn't refuse.

Yang Rui raised his hand to look at his watch twice before Pang Duan noticed his movements.

Pang Du stopped nervously, apologized again and again, and said: "I'm sorry, I'm sorry, I have this problem as soon as I speak, you must be very busy today, I'll come back another day, come back another day." ”

"Don't mind, if you have anything to say, just say it at once, don't change the day. ”

"Then I said it. ”

"Say it. ”

"That's it, I'm a little embarrassed, what do you think, I have a table in Donglaishun, how about we go to Donglaishun at noon to solve it? ”

How could Yang Rui accept his invitation, he immediately shook his head and said, "I'm really busy, just treat it, there's no need." ”

"This ......"

"If you don't, I'll be gone. ”

"No, it's not ......" Pang Dui stopped him cautiously and said, "It's easy to say, I just want to apologize to you, and then please tell the principal, just forgive me, just say forgive me, just do it." ”

Yang Rui said strangely: "What does this have to do with the principal?"

Pang Dui's face wrinkled, lowered his head, and said, "I'm worried that the principal will transfer me." I've done a good job in the Academic Affairs Office, but if I get transferred, all the hard work of the previous years will be in vain, and you have a lot of them, so forgive me. ”

Yang Rui nodded suddenly, thought about it, and said: "This matter is true, you see how it is, I will understand the situation, if it is indeed because of my reason for the transfer, I will tell the principal, how it is." ”

Woe to his children, he was very unhappy with Principal Pang, but he didn't care about Principal Pang's son.

"Okay, good ......" This result was not what Pang Du expected, he hesitated for a moment, and then said expectantly: "If it doesn't affect the promotion, then it's the best." ”

"Promotion?"

"That's it...... This year, there was a vacancy in the Academic Affairs Office, and I should have a chance, so I would be grateful if you could tell the president that you have indeed forgiven me. Pang Dusk's eyes were shining with starlight, looking at Yang Rui like a cat.

Yang Rui suddenly thought of Professor Jia Wanli's reminder: Look at people more accurately.

Pang Dusk's thick eyebrows and big eyes, if he is a good person, he can't look crooked.

"I know, I'll give you an answer after I understand the situation. Yang Rui did not agree, nor did he refuse, and used the procrastination trick.

Pang Twilight watched him leave with starry eyes, and only then did he kick the tree hard, and the leaves were all over his body, and he returned in a huff.
