Tao Li has not felt the joy of doing problems for a long time, although he has been exposed to high school mathematics competitions since last year, but whether it is the finale of the mathematics test paper or the various questions in the competition, for Tao Li, it cannot be compared with the professional courses in college.

Those so-called high school math problems, in Tao Li's eyes, are really just appetizers, solving these problems, playing skills, but like the problems in advanced mathematics, playing is brainpower, pure brain-burning!

Tao Li likes the feeling of burning your brain!

At this time, Tao Li's brain is running rapidly, just like a high-performance supercomputer, Maxwell's equation has been selected as one of the ten most beautiful formulas in the world, and the mathematical theoretical knowledge contained in it is definitely not as simple as it seems, so Tao Li can't do it for a while, but it is normal.

In this way, time passed minute by minute, and Tao Li was completely immersed in this question and couldn't extricate himself, completely forgetting his original purpose, just to wait for Chen Tianxiang, who had a stomachache to go to the toilet.

After Chen Tianxiang solved his personal problems, he came out of the bathroom, looked left and right, and was stunned that he didn't see Tao Li.

"Where did this Teacher Tao go?" Chen Tianxiang muttered as he walked down the aisle.

"Hey, I said where did you go, it turned out that you were hiding here to do the questions? Do you like doing the questions so much?" Chen Tianxiang walked around, and finally saw Tao Li in the classroom, so he couldn't help but walk in and said.

"It's coming out so soon! I thought I'd have to wait a while. It's not idle and boring, so it's just used to pass the time. Tao Li heard that it was Chen Tianxiang's voice, and said without looking back.

"Your way of passing the time is quite special! But I can't understand any of what you've written. Chen Tianxiang stepped forward, looked at so many familiar and unfamiliar mathematical symbols, and couldn't help but have a headache and said.

He has been in contact with high school mathematics for more than ten years, and he has almost forgotten the knowledge of mathematics in college, where can he still understand what Tao Li wrote.

"Wait two more minutes, and it's going to be done. Tao Li did it to the end, and he couldn't bear to give up like this, so he accelerated the speed of doing the question.

As a math teacher, Chen Tianxiang of course knows that this kind of feeling of not being able to do it halfway through the problem is like not being able to get in, so he didn't rush it, sat quietly on the chair, and quietly watched Tao Li "pretending to be forced".

"Whew~ It's finally done!" After about five minutes, Tao Li shook his slightly sour right hand and said in a comfortable mood.

"Is it cool?" Chen Tianxiang put down his phone and asked angrily.

"Cool!" Tao Li replied with a smile. If he hadn't done this question, Tao Li would definitely not have been able to sleep tonight.

"Then let's go back quickly! It's almost eleven o'clock when we get to the hotel!" Chen Tianxiang put away his mobile phone, stood up and said.

As soon as the two of them walked out of the classroom, they met two young people who were about the same age as Tao Li, and the two young people walked into the classroom where Tao Li was originally located while talking and laughing, one of the two people was called Tian Yinong and the other was Zhang Xiaobin, both of whom were third-year students of the School of Physics of Yan University.

Originally, the two of them were going to go to this classroom to discuss the solution of this problem, but there was something temporary in the laboratory, and the two of them had to return to the laboratory, and they were busy until now before they had time to come back. But what they didn't expect was that as soon as the two of them entered the classroom, they were immediately stunned by the scene on the blackboard, only to see that the blackboard was densely filled with the problem-solving process, which had a lot of mathematical symbols, and even they felt unfamiliar.

"What is the situation? Why hasn't it been more than an hour, and the blackboard is full of these things? Do you see if it's written correctly?" asked Zhang Xiaobin, holding his glasses.

"I'll take a look...... It seems like it's right! But it's too complicated! No wonder I can't do it. With such advanced mathematical knowledge, even if you are a graduate student in the Department of Mathematics, I am afraid that there are few who know it!" Tian Yinong also said in surprise.

"The point is, who will make this question? I don't understand it, it's good to find it and tell us about it!" Zhang Xiaobin touched his head and said helplessly.

Although it is said that people who are engaged in physics will not have bad mathematical knowledge, but generally speaking, in order to save trouble, they will leave the calculation process to the computer, and only need to program and input MATLAB, and they can automatically get the desired result, which requires them to calculate by hand!

"Do you think it could be the two people we met just now?" Tian Yinong suddenly remembered that before they entered the classroom, they seemed to see Tao Li and Chen Tianxiang walking out of the classroom!

"It's really possible! I seem to see them coming out of the classroom!" Zhang Xiaobin patted his head, as if he remembered something.

"Let's go, let's stop them and ask them if they really did it, and if they really did it, we might as well ask them to tell us about it." With that, Tian Yinong rushed outside the classroom.

chased until the door of the teaching building, Tian Yinong saw Tao Li and Chen Tianxiang who were about to go out.

"Wait a minute, you two!" Tian Yinong couldn't figure out what Tao Li was doing, so he could only whisper in the back.

"Are you calling us?" Chen Tianxiang turned around and asked curiously.

"That's right, teacher, I want to ask, did you solve the Maxwell's equation on the blackboard just now?" Looking at Chen Tianxiang's age, Tian Yinong naturally regarded him as the teacher of Yan University, so his tone of voice was also a lot more respectful. As for Tao Li, who was standing next to Chen Tianxiang, he was regarded by Tian Yinong as Chen Tianxiang's graduate student.

"What Maxwell's equations? Oh, you mean the question on the blackboard!" Chen Tianxiang was a little confused at first, but soon remembered what Tian Yinong was asking.

"Yes, yes, yes, you made it, teacher, can you explain to us the idea of solving the problem! There are several steps on the blackboard to solve the problem, and my classmates and I can understand it!" Tian Yinong scratched his head and said embarrassedly.

A third-year graduate student in the Department of Physics is not good at mathematics, and it is embarrassing to say it.

"You're mistaken, I didn't make that question, he made it. Chen Tianxiang pointed to Tao Li on the side and said.

Tian Yinong was stunned, he didn't expect it to be made by this young man, it seems that he must be a top student of the Academy!

"I don't know this classmate's surname?" Although Tao Li looked younger than himself, Tian Yinong was still very polite when he spoke.
