Chapter 120 The gap between mathematics and physics is not that big

Next, their topic can be studied as follows. Lin Xiao's step directly solved the primary problem they are currently facing.

"Finally, we have reached a stage where we can now formally consider the situation in a two-dimensional nonlinear elastodynamic system."

Cao Chengqing said with some excitement.

"Yes."

Tang Qing also nodded.

The two professors felt relieved for a moment.

Every step of the research on this kind of topic is quite difficult. Any breakthrough can make them excited. After all, it also means that they are getting closer to their goal.

"Then, in the next week, let's start studying the following directions." Tang Qing nodded, "For the next work, the main task is to establish an incompressible elastic dynamic system in the Lagrangian coordinate system, and Given its basic properties, Xiao Huang and Xiao Tang, you two will be responsible for leading your juniors to continue searching for documents. If you have any questions, just come to me."

Xiao Huang Xiaotang was one of the two postdocs. When their supervisor said this, they agreed.

Then Tang Qing looked at Lin Xiao again, and then said with a smile: "Since Lin Xiao has joined our research group today, let's go have a meal together, and we can use our funds again."

Lin Xiao nodded: "Then it's better to be respectful than to obey."

Tang Qing patted him on the shoulder with a smile and said: "You are still polite when you talk. We study mathematics and don't have to do this. Oh, by the way, you can't wrong you in our research group. Every month I’ll give you a salary of 30,000 yuan until the day they solve the problem. In addition, you don’t have to save money when you go to eat. Just take the invoice after eating and we will reimburse you."

Hearing Tang Qing's words, Lin Xiao couldn't help but be surprised. Just ask for 30,000 yuan a month?

"Isn't this... no need?"

"Hey, why are you so polite? Just take it if it's given to you. I'm still worried about how to spend the funds for our project. Just send me your bank card number later." Tang Qing settled the matter without any explanation, and then he said: " Okay, let’s go now and find a roast duck restaurant nearby. Have you ever eaten roast duck in Beijing?”

"I've had it before."

"Haha, then go and experience the roast duck near Beijing University. The taste is guaranteed to be no worse than that of other places."

With that said, Tang Qing grabbed Lin Xiao and took the others to eat together.

In the original plan, Tang Qing had no intention of inviting Lin Xiao to dinner. Even if it was to offer a salary, he planned to offer a salary of 8,000 from the beginning, which was the same level as several of his graduate students. As for the postdoctoral fellow, it was 10,000.

For the same reason, he didn't expect Lin Xiao to be able to provide any help to the project at first, but looking at it now, Lin Xiao actually brought him a huge surprise in terms of mathematical methods. He just showed it casually today. Solve the problems they are currently facing.

Although the problem Lin Xiao solved was in the category of mathematics and had little to do with physics, their study of mathematical physics was not just about using mathematics to solve it.

From this point of view, as long as they convert physical problems into mathematical form and then hand them over to Lin Xiao to help solve them, how much time will be saved for them?

Tang Qing suddenly felt that he had dug a huge treasure.

Then spending thirty thousand yuan a month is nothing.

…

Soon, they arrived at the roast duck restaurant and found a private room. There were nine people in total, so several plates of roast duck were served directly, as well as some other dishes.

As for wine, I didn’t order anything else. After all, Lin Xiao doesn’t drink, so just have some drinks. Although the academic circle in China is not as pure as other circles, and the wine culture is also prevalent, but for small gatherings like theirs, If you don’t need to drink, there is no need to drink.

Soon, after eating and drinking, it was time to go back.

"By the way, Lin Xiao, where do you live? I'll give it to you."

After eating, Tang Qing's car drove over.

As an academician, he is equipped with a driver and secretary, so Lin Xiao came here in his car just now.

Lin Xiao was not pretentious and said, "Sorry to trouble you, I live in Yanbeiyuan."

"Haha, no trouble, Yanbeiyuan. I used to live there when I was not an academician. Later, when I became an academician, I moved to another place. I miss it a little. It was a long time ago. .”

While talking, the two got in the car again. Tang Qing said, "By the way, do you plan to develop into physics in the future?"

Lin Xiao said: "It's mainly about mathematics, but you can also study physics."

"Well, in the future, if I still have some math and physics topics, I'll come to you for help."

Tang Qing said half-jokingly.

Of course, Lin Xiao did not refuse: "That's definitely no problem. It just so happens that I can also learn from you."

"Haha, that's settled."

Tang Qing clapped his hands and smiled heartily.

"Of course, to be honest, your mathematical talent is really very good. If you can really develop into mathematical physics, you might be able to come up with some good things. I thought before that you were studying number theory, which might be related to Our subjects are somewhat different, but today, you brought me a huge surprise."

Lin Xiao smiled and said: "Actually, I feel that the gap between mathematics and physics is not that big. As long as it can be expressed in a mathematical way, the feeling is not much different, right?"

Tang Qing: "..."

Not big?

It does seem a bit small...

But it's not that much different.

Lin Xiao continued: "But looking at it now, only some problems in physics can be expressed mathematically."

Tang Qing was too lazy to worry about the big difference between mathematics and physics, and said: "Haha, that's not necessarily true. Now there are computational chemistry, computational biology, and computational materials science. Aren't they all related to mathematics? Of course. , I’m not saying this to ask you to go and study these things, as well as the mathematical physics I just mentioned. If other people in our college know that you leave pure mathematics alone and come to study applied mathematics, I’m afraid You have to cause trouble for me.”

"Isn't that enough?"

Lin Xiao couldn't help but open his mouth in surprise.

"That's very serious."

Tang Qing shook his head, "Those who study mathematics look down on other subjects, and those who study pure mathematics look down on those who study mathematics. Who makes pure mathematics more difficult than other subjects?"

"So they will definitely think that you should study mathematics with peace of mind, such as your number theory, or algebraic geometry. Recently, I have heard about Lin's conjecture, which is famous in our mathematics community."

Hearing Tang Qing's words, Lin Xiao couldn't help but feel funny. The disciplinary contempt chain is really something that makes people laugh or cry.

Of course, as far as he is concerned, it is still more important to apply what he has learned. Studying more difficult pure mathematical problems is to challenge the limits of wisdom, and applying mathematics to the research of other disciplines is also to show the strength of his research. Things have a certain practical meaning.

In this way, while the two of them were chatting, the car drove to the entrance of Yanbei Garden.

"Academician Tang, I will go back then."

"Well, bye."

Tang Qing waved his hand and said with a smile: "Then I wish you can go further and further in your academic career."

"Thanks."
