Chapter 97 "A Numerical Simulation Method of Turbulent Flow Based on Differentiable Neural Networks"

Facing the other party’s doubts, Professor Daniel smiled.

After pausing for a while, he said, "Although the error between calculation and experiment is a little larger, I think it is acceptable. These optimizations are very difficult and cannot be completed by one person. They have to rely on the joint efforts of all colleagues."

"Although this material has not appeared for the first time, its mechanism is something we have never understood. Now, it has given a brand new clue and a brand 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. Do you think it can?"

One of the core problems of many physics, such as some superconducting materials, cannot continue to develop, is that most of the calculations in physics are based on perturbation expansion methods.

As long as the expansion parameters are small enough, you can only take the first few items of the perturbation expansion and omit the latter, which greatly simplifies the problem.

However, for some eccentric materials, perturbation has proven to be a dead end.

To further understand them, non-perturbational computing methods must be developed, which is a huge challenge for humans.

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

Xia Xu nodded. He could not mess around with his current identity and make things difficult for a junior. "From this perspective, it is indeed a very good paper. Congratulations, Mr. Daniel, your school journal has another result."

After ending the entire peer review process and receiving congratulations from competitors, Daniel was in a good mood.

He asked casually: "Principal Xia, what good papers do you have there? You can share them together. Europa is coming soon and if you don't publish them, everyone will hibernate."

Relatively speaking, Xia Xu's mood was not very good. He said expressionlessly: "I'm sorry, there are no particularly good results yet... According to the language of our Xia people, this kind of thing also depends on fate, right?"

Daniel asked with a smile again: "That's true. The poor experimental conditions have hindered a lot of work, otherwise we could do better."

"By the way, Academician Ding's students are not turbulence problems? Recently, they have been borrowing our school's laboratory. The turbulence problem is a world-class problem!"

Xia Xu smiled and said, "Oh, I have heard of this. Do you really expect him to achieve a particularly good result? His father's algorithm is good enough for turbulence, and the research is too difficult. Even if his mentor Ding Zhaodong himself worked hard for ten or eight years, he might not achieve anything."

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

"That's true...I've heard that someone is thinking about the Goldbach conjecture?"

"It's great to be young, you can challenge these difficulties fearlessly."

"I also studied this issue, but because of my poor algebra foundation, I quickly gave up..."

"Oh, is that?"

Masters and PhDs are the most creative age group in life. Many major scientific research results are made at this age group.

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 you will no longer have the courage to challenge those problems.

The two of them sighed a little. They started talking about administrative work again.

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

"This is also a problem I am thinking about. The old system has various disadvantages, but it has indeed solved many problems. Relying on personal moral qualities is definitely not enough."

"…By the way, are there any plans for the next hibernation time, how to manage the school?"

"Those who have already passed the postgraduate entrance examination can postpone hibernation for one or two years. The specific hibernation arrangements must be planned by the captain's office."

...

Just as this group of people was in full swing about the entire new civilization planning, the editor-in-chief Zhang Xiaoyong, who was sitting aside, suddenly received an email.

He glanced at it and, by chance, clicked the title.

"A Numerical Simulation Method for Turbulence Based on Differentiable Neural Networks"

I don't know why, but I just saw a title and my heartbeat speeds up sharply.

Let’s take a look at the author’s name Zhang Yuan again!

"I'll go... This Zhang Yuan actually contributed the article?"

I swallowed my saliva and my nerves were a little nervous.

It is actually not polite to look at the phone for a long time during the meeting, but Zhang Xiaoyong stared at the phone screen without moving, and couldn't move it.

He looked at various formulas and words, and sweat oozed out of his forehead, because the knowledge inside began to slowly exceed what he knew.

The direction he did, materials science, was a bit far from this field, so it became increasingly difficult to keep up with the ideas in the above article.

Finally, he couldn't help but shout.

"Principal Xia!"

"What's wrong?"

"I have some urgent matters. If nothing happens here, I will go back first!"

When Xia Xu saw his strange expression, he realized that something seemed to have happened, "Then you go back first, I'll come later."

If you come one minute later, it will be your own loss! Don’t blame me for not telling you!

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

He couldn't wait to rush to Ding Zhaodong's office and shouted loudly, "Old 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 so few minutes later than I expected..."

"Is your paper true or false?"

"What does this paper mean? It was written by my student Zhang Yuan. Don't make it wrong. My name is not written on it, it was completed independently by him!"

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

Ding Zhaodong was calm: "Do you suspect that my student data is fake? I was watching the whole experiment."

"This is so surprising to me. Although I don't understand it very well. However, the experimental effect is too good, it is stronger than Zhang Qiming's algorithm? What's the situation!"

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

Zhang Xiaoyong also laughed loudly. He couldn't wait to see Daniel's embarrassed expression.
Chapter completed!
