Chapter 13 I thought about it

[The registration list for next week's physics competition is as follows, please see if there are any problems.] 】

Two days later, Li Mu was walking on the way to Professor Lin Yao's office when he suddenly saw a list sent by the class leader in the class group.

This is the physics competition that they said two weeks ago when they took Professor Wu Mengyuan's class, and if they get good results, they will have the opportunity to participate in the International Collegiate Physics Competition.

For this competition, although Li Mu is interested, but now he is not here.

Today, his only interest is writing papers.

Just like at this time, he was about to take the paper that he had translated and repeatedly confirmed that there was no problem with the layout and formatting, and let Professor Lin Yao see if there were any problems.

Looking at the list sent below, he nodded curiously, wanting to see who in their class had registered.

The list contains all the applicants for each grade and class, and there are quite a few applicants in the sophomore and junior years, as for the seniors?

The senior year is ready to graduate, and of course he won't participate in this kind of competition, so the sophomore and junior years are basically the main force.

As for the freshmen, although there are some, but there are very few.

However, when Li Mu saw the number of applicants for the international class of physics in their department, he couldn't help but be amazed, worthy of being an international class.

The international class is a cooperative class between Shanghai Jiao Tong University and foreign universities, mainly with Duke University and the University of Maryland in the United States, and the classes are all taught in English.

In terms of the quality of students, on average, it is slightly higher than that of ordinary classes, after all, the score line for applying for the exam is there.

Of course, the important thing is to have money.

Take a look, there are twenty applicants for their freshman international class, and I'm afraid that the whole class will come.

Tut-tuk a few times, and then he looked at the number of applicants in the class, there were very few, the few Li Mu who signed up had heard that they had all participated in the physics Olympiad in high school, and they were considered competitive talents.

No longer paying attention, he casually turned off the interface, and he also came to the door of Professor Lin's office.

There was a knock on the door, followed by a "Please come in" from inside, and he walked inside.

As a result, what made him a little stunned after walking in was that Professor Wu Mengyuan was also there.

Last time I went to Professor Wu Mengyuan, Professor Lin Yao was there, and now when I go to Professor Lin Yao's office, Professor Wu Mengyuan is here again.

Both of them were standing next to a small blackboard at this time, as if they were studying something.

"Professor Lin, Professor Wu."

Seeing Li Mu come in, Wu Mengyuan greeted with a smile: "Xiao Li is here." ”

Lin Yao also nodded to him and said, "You sit down first, Professor Wu and I are still discussing a problem." ”

Li Mu nodded, then sat to the side and glanced at the office, where several seniors were reading or writing at the desk.

Well, all hard math people.

Retracting his gaze, he looked back at the problem the two professors were working on.

It's a mathematical matrix, and of course, the main thing is that there are some physical things mixed in it.

The content of linear algebra is obviously of the difficult kind, because the two professors are arguing about the next steps.

"You're obviously not good, we're going to get the unit matrix now, and your method will definitely not be able to figure it out in the end."

"But what new direction can we think of now?"

"Unless we find a new way to deal with it, hey, maybe that's the innovation of our paper?"

"Then look for it first."

"I'll do the math first."

As he spoke, Lin Yao took out a blackboard marker and began to write.

And Professor Wu Mengyuan was watching from the side, also touching his chin and thinking.

Li Mu didn't know how to do it, the problems studied by the two professors looked very powerful......

He returned to the question that the two professors were working on and looked at the ......

Suddenly, how could Li Mu feel that this thing had a familiar rush?

He pondered for a long time, and finally figured it out.

Isn't this something similar in the paper in his mind that proves Adama's conjecture?

And then follow that method in that paper......

He began the calculus in his mind, and was surprised to find that he had succeeded in finding the matrix of units that the two professors were looking for.

Belch......

Looking at the appearance of the two professors, he hesitated, should he say it himself?

However, as soon as he thought about it in his heart, Professor Wu Mengyuan suddenly looked at him and asked with a smile, "Xiao Li, are you also interested in this issue?" Would you like to give it a try? ”

Of course, Wu Mengyuan's words were just to take care of Li Mu, but he didn't really want Li Mu to give it a try.

It's just that Li Mu heard Professor Wu's words, try it?

Then "try".

"Okay, I'll give it a try."

So saying, he stepped forward.

Wu Mengyuan was slightly stunned, and then there was a smile on his face, since Li Mu had the spirit of this attempt, then he naturally supported it, so he handed the blackboard marker in his hand to Li Mu, and at the same time explained it to Li Mu in his mouth.

"We now need to make this matrix capable of generating singular values similar to singular value decomposition, and you're going to ......"

However, before he could finish speaking, he was stunned.

Because Li Mu had already started the calculation on the blackboard.

And the first step is completely different from what the two of them discussed before.

It's just that this one is completely different, but it has a different effect......

"It's actually to replace the singular value in S with H, and then eliminate the matrix U and V...... Then divide the square of H by ......"

"Wait......"

When Li Mu's first few steps came out, Wu Mengyuan's thoughts suddenly became clear.

"This ......"

He was a little stunned, and then he pulled Lin Yao, who was still calculating by himself, and pointed at Li Mu.

Lin Yao looked at Li Mu suspiciously.

"What?"

Just after glancing at Li Mu's first few steps, he was also stunned.

"This ......"

After a while, Li Mu put down the pen in his hand, clapped his hands gently, and then looked back at the steps he had completed.

"Hmm...... There should be no problem. ”

Immediately, he turned his head to look at the two professors and said, "Professor......"

As soon as he opened his mouth, the two professors stepped forward and squeezed him aside, and then stared at his steps, carefully and carefully from top to bottom, from left to right.

In the end, Lin Yao turned his head to look at Li Mu, his eyes were complicated, although he felt that he was not worthy, but he really wanted Li Mu to apply for his graduate school at that time.

Of course, he still didn't say this sentence, so as not to put pressure on Li Mu.

He said, "Li Mu, you ......"

After he spoke, he didn't know what to say, and finally he could only simply say: "You are the most talented student I have ever met." ”

Wu Mengyuan also nodded in agreement: "It's also the most talented I've ever seen, your favor can be said to have saved us a lot of time at once." ”

"How did you come up with this?"

Although this problem does not bother them in the end, the problem is that the time and effort spent in the middle is not so easy to measure.

Li Mu scratched his head, he didn't expect to be so praised by the two teachers.

He said a little shyly: "Actually...... It's nothing, I just thought about it, and then I just wrote it. ”

The tone was embarrassing, but the words that came out were very interesting.

Lin Yao and Wu Mengyuan both rolled their eyes.

I thought about it and then I wrote it out?

It felt like he was laughing at the two of them.

Of course, they wouldn't be angry about it, after all, Li Mu was also unintentional.

What's more, Li Mu seemed to really think about it just now, and then wrote out the question?

After all, they haven't been here for long.

This made the two professors wonder, what is inside this young man's head?

At this time, Lin Yao suddenly asked, "Li Mu, why don't you come and participate in our current project?" ”
