Hello students, I believe you should already know my name. ”

"Peng Xuelin."

Peng Xuelin turned on the computer and projector on the podium, and wrote his name and phone number, as well as an email account number, on the blackboard.

"What about me,It's everyone's thermodynamics teacher this semester compatible with the class teacher.,If you usually have any questions.,It's okay to call and email to ask me.,Or directly on QQ.,It's okay to say it in the class group.,Don't be embarrassed.,The teachers won't leak your news.。

"I once had a student who liked to send me an email to ask questions, so if you have such a student, you can also learn to write it."

Peng Xuelin laughed.

The teacher looks serious, but the beard on his mouth is curled up one after another.

The students also cooperated and burst into laughter.

"Today is the first time we have officially met, and in the first class, let's take a roll call first and get to know everyone." Peng Xuelin took out a roster or called names, and the students also said "yes" very cooperatively.

There were 38 people in the class, and all of them were there.

Immediately afterwards, a PPT appeared on the projector, and on the first page of PTT, the words "metaphysics" were written.

"Are there any classmates who can say what metaphysics means?" Peng Xuelin asked.

There was a commotion in the class, but I didn't expect that the first lesson of physics would actually examine the knowledge of literature. A few girls raised their hands, and this little problem still couldn't help the top students.

"You don't need to raise your hand, just speak directly, we don't have as many rules in high school in college, just feel free."

Peng Xuelin laughed, very satisfied with the positive response of the students.

"Metaphysics is the study of the causes and origins of all beings and phenomena, and when studying a certain problem, it is necessary to still figure out the details of this thing, and then to study other things related to this thing."

Gu Tunan sat in the front row and was the first to make his own voice.

The class was quiet, and Peng Xuelin nodded: "Well, yes, I learned something." ”

"Our Gu Tunan is the gold medal champion of this year's physics international competition, everyone should know it, his spirit of studying physics is still good, everyone can learn more from him."

Peng Xuelin glanced at Gu Tunan with satisfaction, and then looked at the classmates, and did not turn the PPT page, but walked straight down, closer to the students.

"The entire education system we have established today is actually borrowed from the Western education system in many places, and I will not be told to you that after I finished my graduate school at Peking University, I also went to the UK to study for a doctorate, and at the same time studied some problems in the education system."

"In our current education system, many things are clearly divided, of course, this method is very scientific, mathematics, physics, chemistry, biology, each branch has enough things for us to learn."

"But in fact, this world is not like this, metaphysics is a philosophical point of view, in this world, everything is chaotic, although in the experience of our predecessors, all the knowledge is classified, so that we can learn one by one, but when we study it ourselves, many times we will find that all kinds of branches are entangled."

"Especially when future generations are building on what they have learned and then moving forward, it's a very, very difficult and complicated journey."

"Let's take calculus as an example, it's not that there was something called calculus in mathematics at the beginning, it didn't exist at the beginning, but when a physicist was researching, he found that there was a thread in the mess that he couldn't figure out, so he began to think about what to do, and finally everyone found that a new set of mathematical tools needed to be developed at this time, so calculus appeared."

"For example, if you want to study physics, and you find that you need to find the original materials in English after you have learned a certain level, so you start learning English. After you have learned almost English, you find that you need a certain amount of computer knowledge to conduct the test, so you need to learn computer science at this time. ”

"When the required computer reaches a certain level, you will find that there are some deficiencies in mechanical learning and neural networks, or that the hardware conditions are not enough, and if you want to solve the heat dissipation problem of large-scale computers one day, you must learn the physical specific heat capacity of thermal."

"The essence of this world is a mess, in your future learning process, I hope that you can learn the ability to deal with new knowledge, and be able to untie each mess one by one, so as to understand the world more clearly."

......

Peng Xuelin's eyes at the students were full of enthusiasm.

After saying this, I talked a lot about physics.

For example, in the current socio-economic conditions, he clearly pointed out that it is not so easy to find a job after graduating from physics, but there must be such a group of people in society who dedicate themselves to the progress of science.

For example, the frontier of physics has reached a very far-reaching place, and it must be accumulated for a long time before it can slowly take a step, but this step is a big step for the treasure of the entire human civilization.

All the students were very quiet.

Listening carefully to the teacher's introduction, Zhuge Chuixue on the side didn't open his mouth to ridicule the beard, and there was still some shame on his face, as if he felt guilty because he had teased the teacher's beard before.

Even Su Mu, who has never listened to lectures much.

This time, it was also rare to be engrossed.

He used to read books and learn by himself, but he didn't communicate with the teacher when his grades were poor, and he didn't need to communicate with the teacher when his grades were needed, and he didn't feel this kind of resonance between teachers and students for a long, long time.

With the study of the five major subjects, Su Mu had already begun to perceive the problem that Peng Xuelin said.

Many aspects of knowledge are inherently intertwined.

And the sense of mission that Peng Xuelin mentioned later is also something that Su Mu is pursuing now.

He suddenly became in awe of the teacher.

In this world, in addition to him, there are also countless predecessors who are working hard to make the world better.

Suddenly I felt a little lucky.

I can come to this place.

Meet such teachers.

Meet such a group of classmates.

There can be such a group of like-minded people.
