"Actually, I'm still sorry for Mr. Chen, he didn't catch up with the good times, and his reputation in China is still worse than that of Mr. Hua's boss. ”

"It's okay, time will tell. ”

Since the reform and opening up in the 80s, Mr. Chen was invited by an old man who drew a circle in the South China Sea to return to China, and has been working for the national education cause all his life, which is admirable.

"I'm still sorry for Mr. Hua, if it weren't for the detours in the country in the early years, the world mathematics trophies would have been brushed all over. ”

"Yes, I think it should be. ”

"We're still talking about status, let's talk about academics. Teacher Qian saw that the teachers sitting here were actually complicated, and they were involved in domestic and foreign disputes.

This is Aurora High School, and another math master is involved, and I hope no one mentions it.

Mr. Zhou has a good view of the overall situation, guiding the topic, saying: "Mr. Hua's academic achievements are mainly concentrated in number theory, Fahrenheit's theorem, Fahrenheit operator, etc., and he is worthy of being the father of modern Chinese mathematics. ”

Mr. Chen's research direction is differential geometry, and he is known as the father of differential geometry in the world. ”

"So I think that the branches and directions of the two research are completely different, and they can't be compared with academic levels, just like the folk say, Guan Gong vs. Qin Qiong is pure nonsense. ”

The discussion continued, all talking about the achievements of the two masters, deliberately avoiding the issue of political identity, and the topic was friendly.

Teacher Zhang from Aurora University was indignant, and these people touted the two people, obviously ignoring one of Aurora's principals, which was worth it.

She sneered and said, "Teachers, haven't you all heard of Mr. Su Buqing? He was also a master of mathematics in that era. In the early years of differential geometry in Huaxia, there was nothing to do with Mr. Chen, and Mr. Su brought it up. ”

The voice fell, and the office was silent.

Mr. Qian's eyes were dark, and sure enough, he still came. Mr. Su's status is obviously worse than the previous two, but in the academic circles in the Yangtze River Delta, this big name has a reputation that surpasses the other two.

This is the Beijing faction, a group of students headed by Mr. Hua Luogeng.

Su Pai, Yangtze River Delta, Jiangsu, Zhejiang and Shanghai, Mr. Su Buqing's disciple group.

In the mathematical community, it is also known as the dispute between the north and the south.

"Don't say it, don't say it, it's not the eighties, it's not that complicated, batch papers, batch papers. Teacher Qian yelled, I can't mention it anymore.

The dispute between the north and the south, when there were countless incidents of love and killing, the apprenticeship was very strict at that time, and it was common to go to tea and kneel.

Mr. Hua Luogeng brought out his disciple Chen Jingrun, Mr. Su Buqing brought out his disciple Gu Chaohao, and Mr. Chen Shiingshen brought out his disciple Qiu Chengtong, all of whom are world-famous mathematicians.

The dispute between the domestic and foreign countries, the dispute between the north and the south of the Beijing and Soviet factions, is also a public opinion war in which side of algebraic geometry is more important.

There is a lot of saliva in the world of mathematics.

————————————

That night, when the paper was distributed, Mr. Zhou said with a gloomy face: "The average score is 11 points, and some people are directly pulled away by more than 10 points in an exam, and they are not ashamed." All of you are geniuses in math, and it is not an exaggeration to say that as long as there is a math test in school, it is not an exaggeration to be the first in every time. Now when you compare, you can see the gap. The ingredients are not watery, just look at the final score, and give me a grip. ”

Mr. Zhou began to explain the topic, and there were only three questions, and he talked for nearly four hours.

It was the first time for Yang Fan to participate in this kind of targeted explanation of Olympiad questions, and he found it very interesting.

For example, in the first question, Mr. Zhou actually used three methods to solve it, which opened his eyes.

"What's the matter with Teacher Feng, how do you feel like you're worse than this one. ”

Yang Fan suspected that Lao Feng was very careless, and he coped with things a little. He also took classes with Feng Yao for a long time, and when the latter lectured on the topic, he often only said one answer, and then said something to go back and think about it for himself.

Obviously, I don't pay enough attention to the Olympiad, and I even don't look down on it. Is it that the horizon is too high?

On the podium, Mr. Zhou explained one by one, and explained all kinds of problem-solving ideas in place, analyzing them one by one from possibility to inevitability.

"Niu B, this is the beauty of mathematics, which is much more interesting than what Mr. Feng said. ”

When a question is presented in another way, students will be amazed whether they have done it or not. Why couldn't I figure it out at the time?

After I finish speaking, I will feel that other ideas are better than what I thought, and I feel very good.

The first day passed peacefully.

Early the next morning, it was another three major algebra problems.

Algebra is not as varied as geometry, there will be many solutions, algebraic steps, basically a kind of inevitability.

In the first problem, let n be a given positive integer, T is a set, and its elements are points (x,y) on a plane satisfying x,y is a non-negative integer and x+y

For this question, Yang Fan calculated it on the draft first, and it took about 20 minutes in total to sort out his thoughts, and according to the steps, he moved to the volume, and when he looked at the time, it only took half an hour.

"I feel that algebra is a little worse than geometry, is it because geometry is changeable, or is it because high school algebra is less difficult?"

Finish the first question and continue to the second question. The following two questions took about the same amount of time, which made Yang Fan feel even more weird.

"It shouldn't be that bad. There were 3 hours left. Is it because after undermining people's confidence yesterday, today we deliberately lowered the difficulty to increase students' self-confidence?"

Yang Fan believes that this answer should be close, and the spirit is always jumping, and it may not be able to get the most ideal effect.

"Yesterday geometry, today algebra, tomorrow may be in number theory. After a week, there will be a comprehensive question, and it will no longer be deliberately classified. ”

Sure enough, as Yang Fan expected, the scores were announced the next night, and two-thirds of them scored 21 points.

From this day, the difficulty of the questions slowly increased, and after two rounds in 6 days, the comprehensive questions appeared, and the difficulty reached the top from then on.

Doing questions, reading books, lecturing questions, repeating for two weeks, no entertainment, no leisure, all students are working hard to get out of the line.

Two weeks later, Yang Fan found that two people in the dormitory had left, and they had been eliminated. Yang Fan couldn't even name these two.

Everyone will take a lunch break at noon to give their brains a break. In the afternoon, I consciously studied in the classroom.

After the evening class, the lights were turned off within 20 minutes, and there was no time to communicate, and even between the four of them, there was a faint hostility.

"This kind of atmosphere, this kind of life, it's not interesting, is this still high school?"

Yang Fan felt too bored, and the topic of the first day was amazing, and when it was similar for 2 consecutive weeks, it lost its freshness.

"It's so boring, I'm not learning math, I'm trying my best to be a problem-solving machine. It's still Mr. Feng's clever methods. ”

After following Feng Yao for several months, Yang Fan never felt that mathematics was boring, and it was only half a month since he came here, so he did the problems and vomited.

"No wonder Mr. Feng doesn't look down on the Olympiad, there is a certain reason. Even my thick nerves were tired, let alone anyone else. ”

Everyone's eyes were bloodshot, as if they were about to fall down at any moment, and they were beating their spirits.

"Hold on for another 2 weeks. ”
