Deep Space Planet Leader

After reviewing the first few questions, Professor Wang Zhong glanced at Zhang Yuan and slowly opened the mouth and said: "The writing is pretty good, it’s neat. Unlike some people I use a lot of computers, and I will not write ligatures. It’s like a dog crawling."

Xu Yunjing, who was standing by, blushed. She said It shouldn't be, right?

No!

It must be someone else.

Wang Zhong didn't care about Xu Yunjing's expression. In his cognition, it is a student's duty to answer the first few simple questions correctly.

Look again, the answers to the medium-difficulty questions are correct.

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

In short, it is still correct.

Wang Zhongchang took a long and deep breath, looked up at Zhang Yuan, and the anger in his heart slowly disappeared.

Look carefully, this young man actually looks pretty good, very handsome, a bit like his father when he was young.

Thirty years ago, the days and nights that teachers and students struggled together have passed for a long time, and they seem to be close at hand.

Time flies so fast!

Senior is always a little nostalgic. After reviewing the test papers, he thought to himself that since these questions have been done correctly, the young man's level is still a little bit, so he won't investigate whether you have gone through the back door.

500 thousand people are also impossible. Everyone is born Saint. There is always a little bit of the habit on Earth, which can only be corrected slowly in the future.

This thing about human affection and sophistication, if it is completely absent, it would be too cold and insecure; but if it becomes a human affection society and bureaucracy prevails, it will inevitably be a huge disaster for a civilization.

Continue to look down.

Hey, the few difficult ones behind...

That's right!

Not bad, very good!

These questions, even for some smarter students, may not be able to correct them.

Wang Zhong’s stern face began to melt, which was a sign that his mood had begun to improve.

The young man is wrong. At this level, there is no need to go through the back door. An astronaut exam is not easy.

Seeing Professor Wang's calming expression, Xu Yunjing also sighed in relief, lingering in her throat for a long time, "the paper was sent wrong", and swallowed again.

Since this guy has done it right, I shouldn’t need to say anything more? Leave it to him!

The last one...

Well, this...

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

Xu Yunjing was watching curiously. The proof of this question was really hard to understand. Moreover, when she took the exam, she was abused so badly that she didn't do it at all.

"Did you make it yourself?" Wang Zhong couldn't help asking.

In fact, he knew in his heart that the questions were all made by himself, and the answers were searched on the impossible online.

"Yes." Zhang Yuan replied.

"Xu Yunjing, do you understand?"

"Huh?"

Xu Yunjing was taken aback for a moment, and was suddenly called, his head confused.

"When you took the exam, it seemed that you didn't answer this question."

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

"No."

"Zhang Yuan, you come to tell her the idea of ​​solving the problem."

Zhang Yuan thought for a while and said: "This A constructed L function has the following properties...The natural inverse functor from the category of the sliding projective cluster to H will be decomposed by any special cohomology theory..."

Xu Yunjingzhuang Make a look of listening carefully, and at the same time look at the Little Junior Brother who just met.

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

First method: If a problem is difficult and there is no way to find it directly, then you can try to think about its equivalent problem.

For a simple example, Fermat’s Last Theorem and Gushan Zhicun’s conjecture are a pair of equivalence problems. Mathematician Wiles proved the famous Fermat's Last Theorem by proving the Taniyama-Shimura conjecture.

Second method: If this question is difficult and there is no way to find the equivalent question, then you can also try to think about a broader question than it.

What do you mean? Let's take Fermat's Last Theorem as an example. The "abc conjecture" is a stronger and broader conjecture than Fermat's Last Theorem. If the abc conjecture is true, then Fermat's last law is a scum, and it can be proved in just five sentences.

Easier said than done.

Overwhelming majority people do the questions, just do the questions purely, without insight into the profound mathematical essence of them, inferences about it, not everyone can.

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

Xu Yunjing was stunned and replied in a low voice: "That...should I understand."

"Really understand?"

Wang Zhong frowns, slowly said: "Then you repeat it again."

"..."

She blushed, feeling 10,000 fuck your mother passing by in her heart, she could only stick out her tongue very distressedly, "...I don’t understand. I just got a general idea. "

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

Blow up the question directly...

Not only was this question blown into feng shui, but the same type of question was solved all at once. .

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

Wang Zhong, frowned, knows that the graduate student he is now leading is not actually a genius. After all, Xisha University is not the first two universities, and the poor quality of students is inevitable.

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

He turned around and said to Zhang Yuan: "Very good proof. Thoughts, but a bit of a fuss, have you read through those documents? The motivation-L function, this is the most cutting-edge mathematics."

Zhang Yuan sorry said: "Just read some introductions, cutting-edge mathematics For me, it’s still too difficult to understand. But I know the nature of these functions, so I used it easily."

Did I use it easily?

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

Professor Wang couldn’t help but laughed and said, “Use the most cutting-edge mathematical theory to solve a math problem in a test paper? Can you use the theorem that you don’t understand? You just trust others like this What if his research results are wrong?"

This is also his consistent style. Anyway, he never praises people...

But in fact, my heart is full of The meaning of appreciation.

What is needed for scientific research?

It is innovation!

Rather than the kind of step-by-step, follow-up guy!

How many people do the topic very difficult to deal with, it is a scum to really start scientific research. Because they can only go around in circles. When I heard cutting-edge mathematics, there was only one reaction: what I can't do, what I don't understand, it is simply Heavenly Book!

They didn’t even dare to pay attention. They simply did not explore the unknown and explore the misty Essence, Qi, and Spirit!

"You said..." Zhang Yuan felt that this was indeed wrong.

Wang Zhong's face became a little gentle, and he didn't dare to fight indiscriminately, which undermined the youngster's self-confidence: "You must be a little more pragmatic in learning. This is not a mistake, but it is not practical enough. However. It’s better to work out the question than not. So this test paper will give you 99 points."

Zhang Yuan was very nodded and admitted wrong: "Sorry, these all are my self-taught Course. I have a deep understanding of my lack of knowledge, and the foundation is not solid, so I want to study for postgraduate..."

"Self-study..."

Wang Zhong came back to His senses, a word suddenly choked in the throat.

What's the situation?

Suddenly remembered, this guy is only an undergraduate!
