Chapter 99

Facing the other side's question, Professor Daniel smiled.

After a pause, he said, "although the error between calculation and experiment is a little larger, I think it is acceptable. These optimizations are very difficult and can not be completed by one person. They have to rely on the joint efforts of all peers. "

"Although this material is not the first time, its mechanism has not been understood by us. Now, it gives a new clue, a new direction. "

"This clue may be a dead end, but there is also a probability that it will lead to another brand new world. Therefore, I decided to admit this thesis. Do you think so? "

One of the core problems why many physics, such as some superconducting materials, can not develop is that most calculations in physics are based on perturbation expansion.

As long as the expansion parameters are small enough, we can only take the first few items of the perturbation expansion and omit the later ones, so that the problem is greatly simplified.

However, for some strange materials, perturbation expansion has been proved to be a dead end.

To further understand them, we must develop non perturbative calculation methods, which is a great challenge for mankind.

Anyway, whether admit it or not, this is really a good paper. Because it uses a non perturbative way of thinking, it is a new idea. Whether there is a new world behind it is another matter.

Xia Xu nodded. He couldn't mess around in this status and embarrass a younger generation. "From this point of view, it's really a good paper. Congratulations, Mr. Daniel, your school journal has another achievement. "

After the whole process of peer review, Daniel was congratulated by his competitors. Daniel was in a good mood.

He asked casually, "headmaster Xia, what good papers do you have over there? You can also share it together. Europa is about to arrive. If it is not published, everyone will hibernate. "

Relatively speaking, Xia Xu's mood is not very wonderful. He said expressionless, "I'm sorry, there are no particularly good results for the time being... According to our Xia people's language, this kind of thing also depends on fate, isn't it?"

Daniel smiled again and asked, "indeed, the poor experimental conditions hinder a lot of work, otherwise we can do better."

"By the way, aren't academician Ding's students engaged in turbulence problems? I've been borrowing our school's laboratory recently. Turbulence is a world-class problem! "

Xia Xu smiled and said, "Oh, I've heard of this, too. Can't you really expect him to make a particularly good result? His father's algorithm for turbulence is good enough, and the research is too difficult. Even if his mentor Ding Zhaodong has worked hard for ten or eight years, he may achieve nothing. "

"I don't know why he chose this subject."

"That's true... I also heard that someone was thinking about Goldbach's conjecture?"

"It's nice to be young. You can challenge these problems without fear."

"I also studied this big problem in those years, but I soon gave up because of my poor algebraic Foundation..."

"Oh, really?"

Masters and doctors are the most creative age in life. Many important scientific research achievements were made at this age.

When you are old and in a high position, on the one hand, your thinking vitality and creativity will decline. On the other hand, you will be dragged down by fame and no longer have the courage to challenge those problems.

They sighed a little. They started talking about administrative work again.

"What do you think of the new scientific research assessment system?"

"This is also a question I am thinking about. The old system has various drawbacks, but it has indeed solved many problems. It is certainly not enough to rely on personal moral character. "

"... by the way, do you have any plans for the next hibernation time and how to manage the school?"

"Those who have been admitted to graduate school can postpone hibernation for one or two years. The specific hibernation arrangements should be planned by the captain's office. "

……

Just when this group of people were making great efforts to discuss the whole new civilization planning, Zhang Xiaoyong, the editor in chief, who was sitting on one side, suddenly received an email.

He glanced and clicked the title.

A numerical simulation method of Turbulence Based on differentiable neural network

I don't know why. I just saw a title and my heart beat faster.

Look at the author's name - Zhang Yuan!

"I'll go... This Zhang Yuan really contributed?"

Swallowed saliva, nervous inexplicably a little nervous.

In fact, it's not polite to look at the mobile phone for a long time in the meeting, but Zhang Xiaoyong stared at the mobile phone screen motionless and couldn't open it at all.

He looked at all kinds of formulas and words, and sweat seeped from his forehead, because the knowledge inside began to slowly exceed the scope of his understanding.

His direction, materials science, is a little far from this field, so that it becomes more and more difficult to follow the ideas above.

Finally, he couldn't help shouting.

"Headmaster Xia!"

"What's the matter?"

"I have something urgent. If there's nothing here, I'll go back first!"

Xia Xu saw his strange expression and realized what seemed to have happened. "Then go back first and I'll come later."

If you come a minute late, it's your own loss! Don't blame me for not telling you!

Zhang Xiaoyong said something in his heart and hurried out of the room.

He couldn't wait to rush to Ding Zhaodong's office and shouted, "Lao Ding, Lao Ding, are you there?"

"Please come in!"

Ding Zhaodong pretended to be serious. In fact, he was happy at the bottom of his heart. "You came a few minutes later than I expected..."

"Is your paper true or false?"

"What is my thesis? It was written by my student Zhang Yuan. Don't make a mistake. My name is not written on it. He did it alone! "

"Is it true or false?" Zhang Xiaoyong shouted anxiously, and his old face ruddy.

Ding Zhaodong said calmly, "do you doubt that my student data is false? I watched the whole experiment. "

"It's amazing to me... Although I don't understand it very well. However, the experimental effect is also very good, which is stronger than Zhang Qiming's algorithm? What's going on! "

"Is it just a surprise?" Academician Ding finally couldn't help laughing, "I think it's fright!"

Zhang Xiaoyong also laughed. He couldn't wait to see Daniel's embarrassed look.

Now let the scare spread further!
