God of black technology

The legendary academician Wang actually came to teach this group of undergraduates. This...is too unbelievable.In fact, when this course was arranged for Wang Yun to teach, this group of students never thought that Wang Yun would actually come to the class.

This was indeed the case before, Academician Wang Yun never showed up.Although I heard that this academician has been at Peking University, but an academician is an academician after all, how could he come to teach undergraduates so easily.Isn't it nice to work on your own topics and projects in the office?Even if it is to hold a symposium or a lecture, it basically belongs to the category of people sitting at home and money falling from the sky.What's the use of giving lectures to this group of undergraduates?

But it never occurred to me that this person not only came to class, but also left his mailbox.

Hey, are you kidding me, the academician's contact information——

Wang Yun looked at the students below who were motionless, as if they hadn't reacted, and looked at the mailboxes on the blackboard.It suddenly occurred to me that there seems to be relatively few mailboxes in China.He smiled and said, "I'm used to using mailboxes at Princeton University, so please settle down, it's not a particularly urgent question, I will reply to you within a week or so. Of course, if you really encounter something Urgent issues or other things may not reply to your emails so quickly. Within about a month, I will solve your questions."

"Besides, I hope you are all right and don't send some junk manuscripts to my mailbox. This is not good!" After Wang Yun finished speaking, he took out the lesson plan and said, "Then, I will give you Tell me about the practical application of the methods of mathematical physics."

"That!" Suddenly a student raised his hand, Wang Yun raised his eyebrows, and before turning around to write on the blackboard, he pointed to the student and asked, "What do you want?"

"Professor." The student looked troubled.

"Just tell me if you have anything to say." Wang Yun smiled at the students, the purpose is to make the students not nervous.

"That is, the practical application of this mathematical physics method, in fact, we have already started to do it before, and have done a lot of experimental data and so on..." Wang Yun nodded as the student said.

It does sound like that. Wang Yun doesn't need to talk about the practical application of mathematical physics methods. After the students finished speaking, Wang Yun said, "Now that you say this, everyone thinks that there is no need to talk about the practical application of mathematical physics methods. Continue to learn about the practical application of mathematical physics methods?"

"This..." The students below look at me, and I look at you.In their hearts, they thought that this is actually no need to study, but the academician standing on the podium is not an academician that everyone can see, which makes them feel a little unpredictable.The method of mathematical physics is indeed a difficult point, but in the last semester, some teaching assistants focused on this thing and let them practice it.Now, why are you talking about this thing again.

Even if you know this thing is very important, you don't need to emphasize it over and over again, right?

The students didn't quite understand and didn't dare to speak.You fell silent in the entire classroom. As a student of the Physics Department of Peking University, it is still possible to be quiet.Everyone looked at Wang Yun timidly, as if they wanted to say something, but they dared not say it.

Wang Yun smiled and said, "If you have anything to say, just say it now. After I write it on the blackboard later, it will be useless to say what you want to say."

Sure enough, an academician is an academician, so--stubborn?

"But Professor, I don't think we need to learn about the practical application of mathematical physics methods."

"you sure?"

"Ah." The student who spoke just now started to hesitate again, not knowing what to say, yes, is he sure that he doesn't need to study the practical application of mathematical physics methods?It seems not.

Wang Yun turned around and wrote a line of formulas on the blackboard, pointing to the formulas and said, "This is a common limit solution to nonlinear partial differential equations. If you can solve this problem with mathematical and physical methods, I can skip it directly. I will teach you something more in-depth, but if you don't make it."

He smiled and said, "Then, I have to tell you about the practical application of mathematical physics methods again, to ensure that you can understand some more in-depth things later."

All the students raised their heads and looked at the formulas on the blackboard. They were all in a bad mood. What the hell is this? How to solve this problem.This... simply touched their blind spot of knowledge.

"Professor, are you sure this is a question for us?" This question does not look like an exercise they should do in their undergraduate years, about the limit solution of nonlinear partial differential equations.Professor are you serious?

"Otherwise?" Wang Yun chuckled, "This question is actually quite simple. If you are really familiar with the methods of mathematics and physics, then this question can almost be said to be easily solved."

The students slandered in their hearts, of course you think this is very simple, otherwise how could you be an academician and we are still undergraduates?But this question is too difficult for undergraduates, how can it be done.It can't be done at all!

The most worrying thing is that they not only have to do it, but also have to do it.Want to give Academician Wang a good impression? Thinking of this, everyone silently started to calculate with their notebooks.

There is no other sound in the whole classroom, it is all the sound made by the students touching the scratch paper with the tip of the pen while calculating.Wang Yun sat on the podium and said with a smile, "I'll give you a hint, you can solve this problem as quickly as possible by making good use of the program."

Program, what program.Some students are still in a daze, while others have already thought of this possibility. Isn't the so-called program the Wang Yun program?This is something that has only recently been incorporated into their textbooks.It is very complicated to learn. Even this group of physics students who are not bad at mathematics are learning harder than each other, and it is said that what they have learned is only the surface of the program.It's hard to imagine how this big guy created this thing in the first place.

Let the students have an urge to beat him up, and most of the students have reacted.

Responding is reacting, but let them use Wang Yungang to solve the problem.Forget it, they are not even familiar with how to use the Wang Yun Program.

You have to use it to solve problems, which is simply too difficult.

For this question on the blackboard, countless students stared at the blackboard in a daze, not knowing where their thoughts had gone.

Wang Yun didn't speak, but just let the students continue to think.

After all, he is a student of Capital University. In any case, even if he can't solve it, he should have some ideas.Therefore, he was quietly waiting for the students to solve the problem.

After more than 20 minutes, Wang Yun coughed lightly and said, "How is it? How are you doing?"

"..." The students looked at Wang Yun speechlessly. What can they do?Of course it's not very good, there are some ideas, but it's simply impossible to solve it concretely.

Wang Yun raised his eyebrows, "It seems that you are still not familiar with the methods of mathematics and physics." After speaking, Wang Yun took the chalk and began to write on the blackboard, and began to explain while writing.

The students were a little confused, most of them could understand, but a small part still didn't understand.

After Wang Yun finished speaking and put down the chalk, the students seemed to have not recovered.

Wang Yun smiled and said, "Okay, that's the end of this lesson, you guys are thinking about it, if you have any questions you don't understand, you can come up and ask me."

Speaking of this, Wang Yun seemed to be searching for something on the podium.After a while, he said, "Exactly, this is our first class, right?"

"..." The students didn't quite understand what Wang Yun wanted to do. The students sitting in the front row nodded slightly. It was indeed the first time for this big boss to give a lecture.The boss is indeed a boss, he solved the problem they thought was very difficult so easily, and he spoke very well.He doesn't know if others understand it, but he does understand it.

"I checked, and there is still half a class left." Wang Yun said holding the roster, "When I was at Princeton University, I didn't like roll call too much. And, generally speaking, Princeton Universities don’t call names. It’s up to you whether you come or not. I’ve already taught you the knowledge, and how much you learn depends on you.”

"However, this is China after all. If I don't roll the roll, it's not good." Wang Yun continued, "A few days ago, my doctoral student was still saying that several students did not come when the roll call. Specifically I don't know who."

"However, I'm starting roll call now. In order not to waste more time, I definitely can't roll roll one by one." Wang Yun smiled, "If you didn't come to class and I didn't get called, then you can only say You are very lucky. But if you are called by me, you will not be there. Unless your final exam results are excellent, don’t think about your usual grades.”

It sounds kind, at least better than some teachers.But in fact, I am afraid that if the roll call is not there, it will be very miserable.

The students began to tremble. Speaking of it, the mathematical physics method is too difficult to understand, and the scope of use is not too wide. Many people will not come to this class.For example, several people did not come to class today.If named, probably...

You can basically say goodbye to this course!

"Okay, let's start the roll call now. The students who have been called can just say one word." Wang Yun took the roster and started to roll the rolls at random. In fact, he just read the name to see whose name is more pleasing to the eye.

Fortunately, all the students who were called today are present.

Wang Yun looked around and chuckled lightly.
