After reviewing the first few questions, Professor Wang Zhong looked at Zhang Yuan and slowly said, "The handwriting is pretty good and neat. Unlike some people who use computers too much, they can't even write words, and they are like dogs crawling."

Xu Yunjing, who was standing aside, turned red. She shouldn't be the one who was talking about it?

Won't!

It must be someone else.

Wang Zhong did not care about Xu Yunjing's expression. In his perception, the correct answer to the first few simple questions is a student's duty.

After looking at the medium-difficulty questions, the answers were correct.

The proven land is pretty good, but the idea is a bit strange, a little different from the normal way...

Anyway, it's quite correct.

Wang Zhong took a long breath and looked up at Zhang Yuan. The anger in his heart slowly disappeared.

If you look closely, this young man is actually pretty good and handsome, and looks a bit like his father when he was young.

More than 30 years ago, the days and nights that teachers and students worked together have passed, and it seems to be close to you.

Time flies so fast!

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

It is impossible for 500,000 people to be born with saints. There is always a little habit remaining on the earth, and it can only be corrected slowly in the future.

If there is no such thing as human relationships and worldly style, it will be too cold and insecure; but if it becomes a human relationship society and bureaucracy prevails, it will inevitably be a huge disaster for a civilization.

Keep reading.

Hey, the difficulties behind...

That's right!

Not bad, very good!

Even some smart students may not be able to get these questions right.

Wang Zhong's stern face began to melt, which was a symbol of his mood starting to improve.

I was wrong about the young man. At this level, there is no need to go through the back door. It is not easy to take the astronaut exam.

Seeing Professor Wang's expression relaxed, Xu Yunjing also breathed a sigh of relief. She said that she had been in her throat for a long time that she had sent a wrong test paper and swallowed it back.

Since this guy has done it right, I shouldn’t need to say anything more, right? What if he doesn’t matter!

The last one...

Well, this...

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

Xu Yunjing watched curiously, and she really couldn't understand the proof of this question. Moreover, she was abused so badly during the exam that she didn't do it at all.

"Did you do it yourself?" Wang Zhong couldn't help but ask.

In fact, he knew in his heart that the questions were all produced by himself, and it was impossible to find the answers online.

"Yes." Zhang Yuan replied.

"Xu Yunjing, do you understand?"

"ah?"

Xu Yunjing was stunned and suddenly called, her head in a mess.

"It seems that you didn't answer this question during the exam."

She blushed and covered her face for a long time before she spit out two words.

"No."

"Zhang Yuan, come and tell her about her ideas for solving the problem."

Zhang Yuan thought for a while and said, "This constructed L function has the following properties... The natural inverse functor of the sliding shadow cluster will be decomposed through any special upward homomodulation theory..."

Xu Yunjing pretended to listen carefully, and looked at the junior brother she had just met.

When talking about mathematical thinking, excellent mathematicians will master several methods.

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

To give a simple example, Fermat's Grand Theorem and Tanyama Shimura Conjecture are a pair of equivalence problems. Mathematician Wiles proved the famous Fermat's Grand Theorem by proving the Tanyama-Shimura Conjecture.

The second method: If this question is difficult and there is no way to find the equivalent problem, then you can try to think about problems that are more broadly defined than it.

What does it mean? Take Fermat's Grand Theorem as an example. "Abc Conjecture" is a more powerful and broader conjecture than Fermat's Grand Theorem. If the abc conjecture is true, then Fermat's Grand Law is a scumbag, and it can be proved in just five sentences.

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

Most people do questions simply, without understanding the profound mathematical essence. Not everyone can learn from one example and learn from one example.

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

Xu Yunjing was stunned for a moment and replied in a low voice: "That... should be understood."

"Do you really understand?"

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

“…”

She blushed and felt ten thousand grass mud passing by in her heart. She could only stick out her tongue with great distress, "...I don't understand very much. I just understood a little."

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

I just burst the topic completely...

Not only is this question blown into Feng Shui, but the same type of question is all solved at one time.

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

Wang Zhong frowned, knowing that the graduate student he taught now is not a genius. Xisha University is not the first two universities after all, and it is inevitable that the quality of students is poor.

"Forget it if you don't understand, no one blames you. Don't pretend to understand in the future."

He turned around and said to Zhang Yuan: "It's a good idea to prove it, but it's a bit of a big deal. Have you read through those documents? motivic-L function, this is the most cutting-edge mathematics."

Zhang Yuan said embarrassedly: "I just read some introductions, cutting-edge mathematics is still too difficult for me to understand. But I know the properties of these functions, so I used it."

Use it with it?

Xu Yunjing muttered in her heart: Why can’t I use it?

Professor Wang couldn't help but smile and said, "Use cutting-edge mathematical theorems to solve a mathematical problem in the test paper? Can the theorems you don't understand be used? You just believe in other people's research results, what if it's wrong?"

This is also his usual style. Anyway, he never praises others...

But in fact, my heart is full of appreciation.

What does scientific research require?

It's innovation!

Instead of the guy who follows the steps and follows the map!

How many people are very good at doing questions, but they are really a scumbag when doing scientific research. Because they can only circle around the existing rules and regulations. When they hear cutting-edge mathematics, they only have one reaction: I can’t do it, I can’t understand it, it’s simply a heavenly book!

They didn't even dare to pay attention to it, and they didn't have the spirit of exploring the unknown and exploring the fog!

"What you are talking about..." Zhang Yuan felt that this was indeed wrong.

Wang Zhong's face became a little gentler and he did not dare to attack randomly, which destroyed the young people's self-confidence: "When doing research, you should be more down-to-earth. Although you can't calculate mistakes, you are not down-to-earth enough. However, it is better to get the questions out than not, so I will give you 99 points in this test paper."

Zhang Yuan nodded very consciously and admitted his mistake: "Sorry, these are all courses I have taught myself. I have a deep understanding of my lack of knowledge and my foundation is not solid, so I want to study for postgraduate studies..."

“Self-study…”

Wang Zhong came to his senses and suddenly choked in his throat with a word.

What's going on?

Suddenly I remembered that this guy is just an undergraduate!
