After reviewing the previous questions, Professor Wang Zhong glanced at Zhang Yuan and slowly said, "The words are written well, and they are neat. Unlike some people who use more computers, they cannot even write hyphens, dog It ’s the same. "

Xu Yunjing, who was standing aside, flushed. Shouldn't she be talking about her?

I won't!

I must be someone else.

Wang Wangzhong didn't care about Xu Yunjing's expression. In his cognition, the first few simple questions that answered correctly were the responsibility of a student.

Look again, the questions of moderate difficulty have been answered correctly.

Prove that it is not bad, but the idea is a bit strange, and a little different from the normal way ...

Anyway, it is correct.

Ye Wangzhong took a long breath and looked up at Zhang Yuan. The anger in her heart slowly disappeared.

Look carefully, this guy is actually pretty good, handsome, and a bit like his father when he was young.

Thirty years ago, the days and nights that teachers and students struggled together had passed a long, long time, and seemed to be close at hand.

Time flies!

The elderly always have a bit of old mentality. After reviewing the test papers here, he thought to himself, since these questions have been done correctly, the young man is still a bit of a bit, so he will no longer investigate whether you have gone through the back door.

With 500,000 people, it is impossible that everyone is a natural sage. There is always a residual of habits on the earth, which can only be corrected slowly later.

If there is no such thing as human affairs, it will be too cold and insecure; but if it becomes a human society and bureaucracy prevails, it must be a disaster for a civilization.

Continue to look down.

Alas, the difficult ones behind ...

I'm right too!

Nice, very good!

These topics, even some of the more intelligent students, may not be able to do the right thing.

The king Wang Zhongban's face began to melt, which was a symbol of a better mood.

I blame the boy wrongly. At this level, there is no need to walk through the back door. An astronaut exam is not easy.

Seeing Professor Wang's relaxed expression, Xu Yunjing was also relieved and wandered in his throat for a long time, "the test curl was wrong", and swallowed back again.

Since this guy has done it right, I don't need to say anything more, right? who cares!

The last one ...

Alas, this ...

A thin layer of sweat came from Professor Wang's head, and his expression became serious.

Xu Yunjing watched curiously beside him. The proof of this question really did not understand. Moreover, she was miserably abused during the exam and did not make it at all.

"Did you do it yourself?" Wang Zhong could not help asking.

In fact, he knew clearly that the questions were all made by himself, and it was impossible to find answers online.

"Yes," Zhang Yuan answered.

"Xu Yunjing, do you understand?"

"what?"

Xu Yunjing froze suddenly, suddenly called, a messy head.

"You didn't seem to answer this question when you took the test."

She blushed and veiled for a long time before spitting out two words.

"No."

"Zhang Yuan, come and talk to her about the idea."

Zhang Yuan thought about it and said, "This constructed L function has the following properties ... The category of sliding projective clusters to the natural inverse functor of H will be decomposed by any special cohomology theory ... "

Xu Yunjing pretended to be a serious listener, while looking at the young master he had just met.

When it comes to mathematical thinking, good mathematicians will master several methods.

The first method: If a problem is difficult and cannot be solved directly, you can try to think about its equivalent problem.

To give a simple example, Fermat's Last Theorem and Taniyama Shimura's conjecture are a pair of equivalence problems. The mathematician Wiles proved the famous Fermat theorem by proving the Gushan-Shimura conjecture.

The second method: If this problem is difficult and the equivalent problem cannot be solved, then you can also try to think about a problem that is broader than it.

What does that mean? Take the Fermat theorem as an example, the "abc conjecture" is a stronger and broader conjecture than the Fermat theorem. If abc's conjecture is true, then Fermat's Law is a scum, which can be proved in five sentences.

It's easy to say, but hard to do.

The vast majority of people do problems, they just do it, without understanding the profound mathematical essence, not everyone can.

Zhang Yuan explained for a long time, Professor Wang nodded with satisfaction, "Do you understand?"

云 Xu Yunjing froze, and whispered, "That ... should understand."

"Really understand?"

King Wang frowned and said slowly: "Then you repeat it again."

"..."

She blushed, feeling that 10,000 grass and mud were passing by in her heart, and she could only spit out her tongue in distress, "... I don't understand. I just understand it."

According to Xu Yunjing's very reluctant understanding, the proof of the last question used a very cutting-edge L function, which is equivalent to driving a bomber and suddenly throwing a nuclear bomb!

Directly blasted the topic clean ...

It is not just that this problem was blasted into feng shui, but the same type of problem, all of which were solved at once.

This is a typical high-dimensional crushing method, full of violent beauty.

Ye Wangzhong frowned, knowing that the graduate student he was taking was not really a genius. After all, Xisha University is not the first two universities, and poor student quality is inevitable.

"Even if you don't understand, no one will blame you. Don't pretend to understand."

He looked back and said to Zhang Yuan: "It's a very good proof idea, but it's a bit overwhelming. Have you read through the literature? Motive-L function, this is the most advanced mathematics."

Zhang Yuan said embarrassedly: "Just reading some introductions, cutting-edge mathematics is still too difficult for me to understand. But I know the nature of these functions, so I can use them easily. .com "

Bian Shun used it?

Xu Yunjing muttered in his heart: Why can't I use it smoothly?

Professor Wang could not help but smile, and said, "Use the most advanced mathematical theory to solve a mathematical problem in a test paper? Can the theorems you don't understand be used? You just trust the research results of others in case Wrong? "

This is also his usual style, anyway, he never praises people ...

实际上 In fact, my heart is full of appreciation.

What is needed for scientific research?

Is innovation!

I'm not the kind of guy who works step by step and asks for pictures!

多少 How many people are doing amazing problems, and really starting research is a scum. Because they can only circle in the existing box. When I heard about cutting-edge mathematics, there was only one reaction: I could n’t do it, I could n’t understand it, it was a godsend!

They dare not even pay attention to it, they have not explored the unknown and explored the spirit of the mist!

"You said ..." Zhang Yuan felt that he was really wrong.

Wang Zhong's face became slightly milder, and he did not dare to strike at random, which undermined the self-confidence of the young man: "How about learning, you need to be more pragmatic. Although you can't count wrong, it's not pragmatic. It's better than not making it, so give this exam 99 points. "

Zhang Yuan nodded admirably: "Sorry, these are all self-study courses. I deeply understand the lack of my knowledge and the foundation is not solid, so I want to study and study ..."

"Self-study ..."

King Wang Zhong went back to his heart, and a word suddenly struck his throat.

what's the situation?

I suddenly remembered that this was just an undergraduate!

Uh ...
