After all, military training starts at 6 a.m., which means he basically has to get up at 5:30.

After taking a shower, Lin Xiao returned to the table on his bed.

There was a stack of draft paper on the table with a series of patterns on it. Lin Xiao estimated that Wang Wei left it when he was studying the problem on this table.

After all, this is a double room with two tables, but Wang Wei is the only one, so he can use it as he pleases.

However, Lin Xiao did not read it, but continued to read his book, because there was still a little content left to finish, and he would probably finish it tonight, as it was only just before eight o'clock.

Soon, after ten o'clock, he put down the book in his hand.

After finishing reading the book, he also received a voice from the system.

"The brain development level has reached 3.65%... very close to the original 4%."

It's just that if he wants to break through 4%, I'm afraid there is still some difficulty. Although reading books can increase his experience and upgrade other subjects to level 2, as far as the current situation is concerned, he still has to read dozens of books to master them all.

Raising it to level 2 would take too much time, and he still had his own things to do.

"Let's take it step by step slowly."

Shaking his head and thinking no more, he stood up and stretched. Suddenly, out of the corner of his eye, he glanced at the pile of draft paper on the table.

"Would you like... to take a look?"

He was rather curious about what the counselor Wang Wei was studying.

So he took it over and looked at it briefly.

[Existence of uniform attractor for supercubic weakly damped wave equation with time delay term]

"Is this the title?"

Lin Xiao couldn't help but be stunned.

This is a physics problem...

But if it is Wang Wei’s research, does it fall into the category of mathematical physics?

Mathematical physics is to seek mathematical descriptions of physical phenomena, and to summarize physical things into the field of mathematics to solve them.

Therefore, strictly speaking, it should belong to the field of physics, not mathematics.

Of course, since problems in mathematical physics have very high requirements for mathematics, not to mention that mathematical physics is not divided into different disciplines, so the gap between the two is not big. Many mathematicians choose to study physics in the end.

It's just that Lin Xiao obviously hasn't studied physics enough to understand these things. For example, he has never understood things like the weakly damped wave equation.

Of course, he still had some interest in physics and started reading from the beginning.

"Hmm... I think you can understand a little bit?"

The first is the time-delay differential equation. Lin Xiao knows this. After all, it is something in mathematics. Anyway, it is a type of differential equation. The main feature is that the derivative of the unknown function at a certain moment is determined by the function at the previous moment.

Lin Xiao had already understood this part when he first learned it.

In addition, some nouns that Lin Xiao didn't know appeared in the scratch paper, but when these nouns were converted into mathematical form, Lin Xiao found that he suddenly understood the physical meaning of this noun.

Mathematics is the language of the universe and can represent everything.

Of course, such a 'representative' is very abstract to others, but it is not abstract at all in front of Lin Xiao.

Some physicists can directly see through the intuitive images behind complex mathematical formulas and proofs. Edward Witten, who proposed the M theory, is one of them. He was able to complete a task that mathematicians have not really understood yet.

When proving, you can directly predict what has been proved, and it is often accurate.

For Lin Xiao at this time, he almost figured out what the physics term meant through this method. If he was really unsure, he could just check it online.

And he often finds that his guess is correct.

I woke up late today, and my hair was a little late...
