All-round mathematician

Chapter 111 The War of Words in Academia
"Actually, I still feel 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 everything."

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

"I feel sorry for Mr. Hua. If it wasn't for the country's detours in the early years, the world's mathematics trophies would have been won all over the place."

"Yes, I think so too."

"We're still talking about status, let's discuss academics." Teacher Qian could see that the grading teachers sitting here were actually complicated, and involved domestic and foreign disputes.

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

Mr. Zhou has a good view of the big picture, and guided the topic, saying: "Mr. Hua's academic achievements are mainly concentrated in number theory, Fahrenheit's theorem, Fahrenheit's operator, etc. He is indeed the father of modern Chinese mathematics."

"Mr. Chen's research direction is differential geometry. There are Huanghuang's masterpieces "Lectures on Differential Geometry", "Differential Manifolds" and so on. He is known as the father of differential geometry by the world."

"So I think that the branches and directions of the research of the two are completely different, and they cannot be compared on the basis of academic level. It is like the folk saying that Guan Gong's battle with 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 praised those two people, obviously ignoring a principal of Aurora University, which is not bad.

She sneered and said: "Teachers, haven't you heard of Mr. Su Buqing Su? He was also a master of mathematics at that time. In the early years of Huaxia's differential geometry, there was nothing like Mr. Chen. Mr. Su brought it up with his own hands. .”

The voice fell, and the office was silent.

Teacher Qian's eyes darkened, but he still came.Mr. Su's status is obviously inferior to the previous two. However, in the academic circles around the Yangtze River Delta, the reputation of this great master overwhelms the other two.

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

Su School, a disciple group of Mr. Su Buqing in Jiangsu, Zhejiang and Shanghai in the Yangtze River Delta.

In mathematics, it is also known as the North-South dispute.

"Don't talk about it, don't talk about it, it's not the 80s now, it's not that complicated, marking papers, marking papers." Teacher Qian yelled, and couldn't mention it any more.

There were countless incidents of falling in love and killing each other during the dispute between the North and the South. At that time, apprenticeship was very strict, and it was common to kneel down while serving tea.

Mr. Hua Luogeng brought out his disciple Chen Jingrun, Mr. Su Buqing brought out his disciple Gu Chaohao, and Mr. Chen Shengshen brought out his disciple Qiu Chengtong. They are all world-renowned mathematicians.

The domestic and foreign disputes, the Beijing faction and the Soviet faction's north-south dispute are also public opinion wars over which side is more important in algebraic geometry.

There is a lot of saliva in the mathematics world.

------------

In the evening self-study that night, when the papers were handed out, Teacher Zhou said with a gloomy face: "The average score is 11 points. In one exam, some people were directly pulled away by more than 10 points. It is not embarrassing. All of you are geniuses in mathematics." , It can be said that as long as the school takes the math test, it is not too much to be the first. Now that you compare, you will know the gap. Whether the composition is good or not, just look at the final score, hurry up."

Teacher Zhou began to explain the topic, 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 Mathematical Olympiad questions, and he found it very interesting.

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

"Then what's the matter with Mr. Feng, why does it feel like he's worse than this one?"

Yang Fan suspected that Lao Feng was very careless, and he was a little bit coping.He also took a long class with Feng Yao. When the latter gave a lecture, he often only gave one answer, and then went back to think about it.

Obviously, they don't pay enough attention to the Olympiad, and even look down on it a bit.Is the vision too high?
On the podium, Mr. Zhou explained one by one, explaining all kinds of problem-solving ideas in place, and analyzed them one by one from possibility to inevitability. Yang Fan listened to it and felt a kind of epiphany.

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

When a topic is presented in another way, no matter whether there are students who have made it or not, they will feel amazing.Why couldn't I figure it out.

After finishing the lecture, I will feel that other ideas are better than my own, which is very emotional.

The first day passed so peacefully.

Early the next morning, there were three big problems in algebra.

Algebra is not as changeable as geometry, there will be many kinds of solutions, algebraic steps are basically an inevitability.

The first question, let n be a given positive integer, T is a set whose elements satisfy x on the plane, y is a non-negative integer and x+y

For this question, Yang Fan calculated on the draft first. It took about 20 minutes in total, and he sorted out his thoughts. According to the steps, he put it on the paper. Looking at the time, it took only half an hour.

"I feel that algebra is a bit inferior to geometry. Is it because geometry is changeable? Or is it because high school algebra is less difficult?"

The first problem is completed, continue to the second problem.The next two questions took about the same amount of time, which made Yang Fan feel even more weird.

"It shouldn't be so different. There are still 3 hours left. Is it because after the confidence was hit yesterday, the difficulty is deliberately lowered today to increase the self-confidence of the students?"

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

"Geometry yesterday, algebra today, and number theory tomorrow. There will be comprehensive questions after a week, and there will be no special classification."

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

From this day on, the difficulty of the questions gradually increased. After 6 days and two rounds, the comprehensive questions appeared, and the difficulty reached the peak from then on.

Doing questions, reading books, giving lectures, repeated for two weeks, no entertainment, no leisure, all students are working hard to get out.

Two weeks later, Yang Fan discovered that two people in the dormitory had left, and they were eliminated.Yang Fan couldn't even tell the names of these two.

Everyone will seize the time to take a lunch break at noon to let the brain rest.In the afternoon, I consciously study by myself in the classroom.

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

"This kind of atmosphere, this kind of life, is boring. Is this still high school?"

Yang Fan felt too bored, and the topic of the first day's explanation became amazing, but when it was similar for two consecutive weeks, it lost its freshness.

"It's too boring. I'm not learning mathematics, but trying my best to become a problem-solving machine. Teacher Feng's methods are brilliant."

After working under Feng Yao for several months, Yang Fan never felt that mathematics was boring. After only half a month here, he could only do the problems until he vomited.

"It's no wonder Mr. Feng doesn't like Orsay. There's a reason for that. Even my nerves are exhausted, let alone other people."

Everyone's eyes were bloodshot, as if they were about to fall down at any time, and they were struggling.

"Persist for another two weeks."
