Chapter 97 A Numerical Simulation Method for Turbulence Based on Differentiable Neural Networks

Professor Daniel smiled at the other party's questioning.

After a pause, he said, "Although the error between the calculation and the experiment is a little larger, I think it's acceptable." These optimizations are very difficult, and they cannot be completed by one person, but rely on the joint efforts of all peers. ”

"Although this material is not the first time it has appeared, its mechanism is something that we have not been able to understand. Now, a new clue has been given, a new direction. ”

"This clue may be a dead end, but there is also a certain probability that it will lead to another new world. So, I decided to accept this paper anyway. Do you think you can? ”

One of the core problems with the failure of many physics, such as some superconducting materials, is that most of the calculations in physics are based on perturbation methods.

As long as the expansion parameters are small enough, only the first few items of the perturbation expansion can be taken, and the latter ones can be omitted, so that the problem can be greatly simplified.

However, perturbation unfolding has proven to be a dead end for some materials with odd properties.

To understand them further, it is necessary to develop non-perturbated computational methods, which is a huge challenge for humanity.

Anyway, admit it or not, it's a good paper. Because it uses a non-perturbated way of thinking, it's a new way of thinking. Whether there is a new world behind it is another matter.

Xia Xu nodded, it is impossible for him to mess around with his current identity and embarrass a junior, "From this point of view, it is indeed a very good thesis." Congratulations, Mr. Daniel, you have one more achievement for your school magazine. ”

After the whole peer review process and the congratulations of the competitors, Daniel was in a good mood.

He asked casually, "Principal Xia, what good papers do you have over there?" You can also share it together. Europa is coming, and if it is not published, everyone will hibernate. ”

Comparatively speaking, Xia Xu's mood was not very good, and he said expressionlessly: "I'm sorry, there are no particularly good results for the time being...... According to the language of our Xia people, this kind of thing also depends on fate, doesn't it? ”

Daniel smiled again and asked, "It's true, the experimental conditions are poor, which hinders a lot of work, otherwise we could have done better." ”

"By the way, Academician Ding's students, aren't they doing some turbulence problem? Recently, I have been borrowing our school's laboratory. The turbulence problem is a world-class problem! ”

Xia Xu smiled and said, "Oh, I've heard of this too." Do you really expect him to do something particularly good? For the turbulence problem, his father's algorithm is good enough, and the research is too difficult, even if his mentor Ding Zhaodong himself struggles hard for ten or eight years, he may not achieve anything. ”

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

"That's right...... I've heard that some people are thinking about the Goldbach conjecture? ”

"It's nice to be young, to be able to challenge these challenges without fear."

"I also studied this big problem back then, but because of the poor algebraic foundation, I quickly gave up ......"

"Oh, really?"

Master's degrees, as well as PhDs, are the most creative age groups in life. Many major scientific research achievements were made at this age.

When you get older and have a higher status, on the one hand, your thinking vitality and creativity will decline, and on the other hand, you will be dragged down by fame and no longer have the courage to challenge those problems.

The two sighed slightly. They started talking about administrative work again.

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

"That's a question I'm thinking about. The old system had all kinds of drawbacks, but it did solve a lot of problems, and it was certainly not enough to rely on the moral character of individuals. ”

“…… By the way, how will the school manage the next hibernation time, and do you have any plans? ”

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

……

Just when this group of people was discussing the entire new civilization plan, the editor-in-chief Zhang Xiaoyong, who was sitting on the side, suddenly received an email.

He glanced at it, and by mistake, clicked on the title.

A Numerical Simulation Method for Turbulence Based on Differentiable Neural Network

I don't know why, just seeing a headline, my heart beats violently.

Look at the author's name again - Zhang Yuan!

"I'll ...... This Zhang Yuan actually submitted? ”

Swallowing his saliva, his nerves were inexplicably a little nervous.

It's actually not polite to look at the phone for a long time in the meeting, but Zhang Xiaoyong's two eyes stared at the phone screen motionlessly, and he couldn't move away at all.

He looked at the formulas and words, sweat oozing from his forehead, as the knowledge inside began to slowly exceed what he knew.

The direction he did, materials science, was so far from the field that it became more and more difficult to keep up with the ideas in the above.

Finally, he couldn't help but scream.

"Principal Xia!"

"What's wrong?"

"I'm in a bit of a hurry, if there's nothing wrong here, I'll go back first!"

Xia Xu saw his strange expression, and also realized that something seemed to have happened, "Then you go back first, 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 muttered in his heart and hurriedly walked out of the room.

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

"Please come in!"

Ding Zhaodong pretended to be serious, but in fact, he was happy in his heart, "You came a few minutes later than I expected......

"Is your paper true or false?"

"What do you call my thesis, it was written by my student Zhang Yuan, don't be mistaken. It doesn't have my name written on it, he did it on his own! ”

"Is it real or fake?" Zhang Xiaoyong shouted anxiously, and his old face flushed.

Ding Zhaodong was unhurried: "Do you suspect that my student data is fraudulent?" I watched the whole experiment from the sidelines. ”

"That's so much to ...... I was pleasantly surprised, although I didn't understand it very well. However, the experimental effect is too good, is it stronger than Zhang Qiming's algorithm? What a situation! ”

"Was 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 expression.

Now let the scare spread a little farther!
