Yan Xiaoke's actions are very efficient, and after eating barbecue on Friday, he made up his mind to prepare to be a small up master part-time.

She has had an account on the barrage network for a long time, and some shooting equipment can also be used directly with a mobile phone or borrowed from Yi Yanyue in the early stage.

Originally, this weekend, Su Mu was also planning to have a warm relationship with Yan Xiaoke, or go out somewhere else to play, but because there were more courses, Yan Xiaoke started to work again and had to be alone.

Yan Xiaoke's account is simply called "Yan Xiaoke", and her first video is just about to make a simple self-introduction.

Listening to Yi Yanyue, it is actually difficult for newcomers to get traffic support from the barrage network, so in the next period of time, Yan Xiaoke will first show his face in Yi Yanyue's video to accumulate some fans.

Even when he said these plans in WeChat, Su Mu could feel Yan Xiaoke's seriousness.

According to Yan Xiaoke's words, Su Mu is very powerful now, and if he wants to get along for so long in the future, Yan Xiaoke doesn't want to drag him back, but also wants to "become a very powerful person".

He could almost imagine Yan Xiaoke's milky expression when he said these words, and his heart was a little mixed.

It's not that she doesn't believe in Yan Xiaoke, if she can find what she likes to do, Su Mu will naturally be happy for her.

Su Mu just felt that Yan Xiaoke now seemed to be a little different from before.

In the past, Yan Xiaoke belonged to the kind of arrogant little princess, but now she has more gentleness and perseverance.

.......

The School of Physics at Peking University enrolls about 200 students every year, with a total of three undergraduate majors: physics, astronomy, and atmospheric science.

Since it was the first weekend since the beginning of the school year, there were not many activities arranged in the school, so I wanted the new students to adapt to school life.

Su Mu still stays in the library every day to read books and brush up on homework.

Originally, when he was in high school, Su Mu always thought that he would be crazy to make up all the computer games he hadn't played before, but he never thought that now he would be happy to sit in the library until dark.

In the midst of reluctance, the new students ushered in the second week of classes, and now the entry and exit of the school is much stricter than before, and the students have also entered an intense learning atmosphere.

On the way, I occasionally encounter students and teachers hurrying by with folders, and if you want to study and research seriously at university, you need to work hard, and the degree of effort is definitely no less than that of the third year of high school.

"Faun, may I ask a question?"

On Monday morning, there was only one hot class taught by the head teacher, Peng Xuelin, and although Su Mu was now the class leader, he still chose to sit in the back row with his roommates.

The students listened attentively to the class, because the class was full of top students, so the speed of the teacher's lecture was also very fast, and he took notes without missing anything.

Occasionally, someone will raise their hand to ask a question about something that students don't understand, and the interaction between the lessons is generally harmonious.

Now is the time to learn knowledge in formal class, and if you miss something, it will take you three, five, or even more time to make up for it after class.

"Huh? What's wrong? ”

Su Mu was also listening to the lecture carefully, and unlike other students, he didn't take notes.

One is because his memory is very good now, and there is not much difference between writing it down and writing it down with his brain, and the second is because he has actually reviewed this knowledge in advance, and the questions after class have already been brushed up by three, five by two, and now listening to the teacher's lecture is just to consolidate the knowledge a little, and by the way, also express respect for the teacher.

At this time, hearing Zhuge Chuixue talking to himself, Su Mu looked a little nervous, to be honest, he was not afraid of how difficult it was to study, he was afraid that Zhuge Chuixue would come up with some crooked ideas.

"There should be five minutes left before the recess, let's talk about something after class." Su Mu opened his mouth and said.

Zhuge Fuxue nodded and quieted down.

In this class, Professor Peng Xuelin's main knowledge point is about the equation of state of ideal gas in thermal theory.

It's an extension of high school knowledge.

When I was in high school, I had already learned the equation of state of an ideal gas in physics, and the meaning of state and state of matter is similar, but it is more comprehensive in terms of state of matter.

The equation is simple and is expressed as pV=nRT. There are 4 variables in this equation:

p is the pressure of the ideal gas, V is the volume of the ideal gas, n is the amount of gaseous substance, and T is the thermodynamic temperature of the ideal gas. There is also a constant R which is the ideal gas constant.

Because there are many variables in the equation, it can be applied to a wide range of applications, and it is also approximately applicable to air at room temperature and pressure.

When I was in high school, it was very simple to learn, but Professor Peng Xuelin only extended it a little, expanding to the average number of molecules colliding per unit area per unit of time, and everything seemed very complicated.

Although most of the students had already prepared in advance, they couldn't help frowning and falling into deep thought when they wanted to sort it out.

Finally, class is over.

A few girls went to the toilet together, a few boys were drinking water and eating, and some classmates were sitting in their seats and continuing to calculate, Su Mu looked up at Zhuge Chuixue slightly: "What happened just now?" You don't think of any strange things. ”

For this second-year sick boy, Su Mu had already given up saving and decided that it would be better to go with the flow.

"No, it's just that I don't understand what the teacher said." Zhuge Chuixue was a little more serious, and said a little embarrassedly: "I see that you haven't taken much notes, because you have learned it a long time ago, so there are a few places I want to ask you." ”

"Hmm." Su Mu nodded, replied indifferently, and was even a little relieved: "Ask... This chapter is actually not that difficult. ”

This is the content of the first two chapters of Thermology, although it is a bit difficult, but it is much simpler than Newton's cooling law and the specific heat capacity content that follows.

"This is the place." Zhuge blew the snow and came out in a few places, and he was not polite.

After all, it is the god of faun, and in the eyes of Zhuge Chuixue, it is still very reasonable to find Su Mu if there is a problem.

"Here." Su Mu thought for a while: "Here is the microscopic model of the ideal gas, the main reason is that the linearity of the molecule itself is much smaller than the molecular spacing, which is negligible, and then it is necessary to take into account the Lochette constant, which is a problem brought into by a formula." ”

"The average number of molecules you will collide on the wall of the device in an average time...."

was a little bored, so Su Mu opened his mouth and explained to Zhuge Blowing Snow.

Anyway, he is idle, and being able to systematically sort out and explain this knowledge is also very beneficial to himself.

Lin Shaojun and Shen Tianhao on the side were also pondering.

Hearing Su Mu explaining Zhuge Chuixue in detail, he couldn't help but turn his head over.

The girls sitting in front of them also turned around and listened carefully, first, they could finally look at Su Mu's handsome face openly, but they could also consolidate the knowledge of the teacher's lectures.

After six or seven minutes between classes, Su Mu unconsciously gathered more than a dozen people here, and the voice of the discussion gradually became louder.
