Zhang Zhai felt very headache about this kind of thing.

Although his knowledge at this time was more than enough to teach these students, he still didn't like this kind of thing.

"This classmate, can we talk about signings after class?" Zhang Zhai said helplessly, "We won't talk about anything else during class time."

"Okay, Zhai Shen, don't forget to sign!"

Well, the student sat down obediently, but other people in the classroom also knew Zhang Zhai's identity.

Suddenly, there was some noise in the classroom, and the whole place was noisy.

"Okay, classmates, let me introduce myself again."

"Yes, I am Zhang Zhai. I have been lucky enough to make some achievements recently. Maybe some of you here have heard of it?"

"But this is not important. What is important is that now, I am the teacher of the classmates present, and the classmates present are also top students in the School of Physics of Peking University and have high-quality talents. So, do you all understand what I mean?"

Zhang Zhai spread his hands and gestured.

The atmosphere in the classroom was finally changed by his few words, and it finally felt like a classroom.

Zhang Zhai secretly wiped his sweat and felt that he had done a terrible job in this class.

A good scientist is not necessarily a good educator.

"This course will now officially begin."

"However, my teaching method may be a little different. If you students have any questions, you can ask Professor Liu later."

"Since I don't know the progress of your course, let's ask the questions first."

Zhang Zhai turned his head and started writing on the blackboard.

"Try to find the particle energy level and wave function in the asymmetric potential (Ε＜ν2)"

Zhang Zhai twice wrote a question on the blackboard.

"Pah!" He tossed the chalk tip coolly.

"Any student who understands this set of questions is welcome to answer it. There is no need for a complete solution, just an idea for solving the problem."

Some of the students below looked at each other in confusion. They didn’t say anything. What’s the point of just throwing out a question?

Suddenly, the classroom was a little noisy.

Although these students admire Zhang Zhai's recent achievements.

However, it is still difficult for these proud people to maintain their trust in Zhang Zhai when they are asked to educate students who are one year younger than them in their own majors.

For a moment, no one responded to Zhang Zhai's words.

Is Zhang Zhai embarrassed?

He didn't feel embarrassed at all. He was also a student and he didn't like answering questions or anything like that.

Just when he was about to make a joke, someone stood up.

"Hello, Teacher Zhang, I think this question should be very simple, the solution of the Schrödinger equation." This is a girl, who looks quite cute, looking at Zhang Zhai, very excited.

"Thank you very much to this classmate for helping me get rid of the dilemma of being ignored." Zhang Zhai smiled and nodded to the girl.

The girl became even more excited, "You're welcome, Teacher Zhang. If you really want to thank me, how about you sign a few more names for me later?"

…

This answer made the students in the classroom couldn't help but laugh, and the atmosphere became more lively.

"Classmate, please sit down."

"This female classmate's idea is very correct. This is indeed a very simple question."

"Let me briefly explain here, first solve the Schrödinger equation, so..."

Zhang Zhai explained this issue in detail and explained the relevant laws to these students.

It took ten minutes.

"It seems that everyone has come into contact with the Schrödinger equation before.

That's just right, let's come today and continue to learn more.

Let’s take a look at this question again.”

Zhang Zhai picked up the chalk and scribbled down another question.

"The motion of particles in a one-dimensional б potential well V(χ)=-αб(x) [α>0] determines the particle's bound fixed energy level and the corresponding normalized stationary wave function."

"Who will answer this question?"

Zhang Zhai had always had a relaxed tone and made jokes from time to time, so the classroom atmosphere was already much more lively at this time.

So, finally, someone spoke enthusiastically.

"Okay, just this classmate, what is your name?"

"Teacher Zhang, my surname is also Zhang."

"Okay, classmate Zhang, come up here. This blackboard is now reserved for you."

Zhang Zhai always felt a little funny when the name "Classmate Zhang" came out of his mouth.

…

Ten minutes later.

"This classmate Zhang's steps are basically correct, but there is one thing he overlooked. Remember to pay attention to it."

Then, Zhang Zhai began to explain this issue.

Just like that, one question followed another.

Ask the questions first, then ask students to answer them, and then Zhang Zhai will make corrections.

The class actually went on so harmoniously.

Zhang Zhai also felt that with such lectures, the knowledge in his mind was constantly being integrated.

After all, when you teach others, you are actually learning it again yourself.

Zhang Zhai talked eloquently, and the students listened with great interest.

No one noticed that there were two people standing outside the back door of the classroom.

"Dean, I think this guy is a physics guy. His talent would be a waste if used in other areas.

With his talent, in physics research, it is not said that he has the same achievements as Einstein, but, at least, China's physics community can truly reach the top of the world in some aspects!"

Lao Liu said to another old man beside him.

This is the dean of physics.

"You are indeed very talented, but..." The dean shook his head. He felt that Lao Liu's idea was too naive.

Even if Zhang Zhai has a talent for physics, is he willing to engage in research in this area?

This kind of boring, boring, day after day, complicated research.

You can't tell when the results will be produced. Even if you work hard and work hard to produce results, how many people can understand? You can't tell even those in the industry can understand.

Real basic scientific research must be lonely and lonely.

I am alone on the road.

Unless you really love him very much, how can you persevere?

Lao Liu was such a person, so he thought Zhang Zhai was too.

…

This class, which started inexplicably, went on in a unique way, and then came to an abrupt end when everyone was still unfinished.

However, Zhang Zhai was relieved.

Not long after class ended

Zhang Zhai must have been blocked by Old Liu in the library.

"How do you feel? Are you happy in class? Are you interested in staying in school and becoming a teacher after graduating from college?"

Zhang Zhai rolled his eyes. It's okay to come to class once in a while.

As a teacher, he was afraid that he would be beaten to death.

"Forget it, I don't want to be a teacher in this life anymore."

"..."

"How do you feel about quantum physics? Isn't it interesting?"

"It's quite interesting. Quantum physics is such a mysterious world." Zhang Zhai said with emotion.

"Have you ever thought about concentrating on research in this area?" Lao Liu stared, looking forward to Zhang Zhai's answer.

At this time, Zhang Zhai finally figured out the cause and effect, and understood the origin of this inexplicable lesson.
