"Starting today, we will officially start the training camp."

In the first class in the morning, Lu Jiaotou suddenly said something that made everyone scratch their heads.

'Formal training camp? So what were we doing before? Play!? ’

Looking at the bunch of confused faces below, Lu Zhi nodded with satisfaction, "First of all, I would like to introduce two of my friends to you." ”

As soon as Lu Zhi's words fell, the two old professors, who were obviously old, walked in slowly and waved their hands to the classmates kindly.

'I always feel like these two are a little familiar......

But before Wu Bin could remember who these two were, Lu Zhi had already invited the two old men to the podium to introduce them one by one.

"This is the scientific research director of basic physics in the Department of Physics of the School of Physics of Peking University, Professor Shu Yousheng."

“……”

"What...... What the!!? ”

The students below were in an uproar, including Wu Bin, the old professor's "Mechanics" made him read it with relish.

"Hello classmates." Shu Yousheng, who was introduced, greeted everyone with a smile.

"Hello Professor!" The students spontaneously stood up and bowed, expressing their respect and admiration for the old professor in the simplest way.

Then, before the students sat down, Lu Zhi introduced the next old professor and said: "This is the former IPhO national coach, Professor Cheng Jiafu of China University of Science and Technology. ”

"What!?"

The classmates were shocked again, especially Wu Bin, who was sitting in the first row, his eyes were almost bursting with stars, and his body took two steps forward uncontrollably.

"You...... Are you Professor Cheng? At this moment, Wu Bin's voice was nervous and a little trembling.

"Hello, classmate." Cheng Jiafu smiled at Wu Bin in a friendly manner.

"You...... Hello. After speaking, Wu Bin took two deep breaths, and then said, "I'm looking at the book you wrote...... No, I should say that physics and I are together under the witness of your book! ”

"It's an honor for you to like the book I wrote." After Cheng Jiafu finished speaking, he stretched out his hand towards Wu Bin.

Wu Bin saw that his hands hurriedly wiped his clothes twice, then shook them, and said excitedly: "Thank you for leading me into the world of physics." ”

"This kid is really interesting." Cheng Jiafu shook hands with Wu Bin and looked at Lu Zhi with a smile.

"This is the Wu Bin I told you about." Lu Zhi replied.

"Oh~ It's you." After listening to this, Cheng Jiafu looked at Wu Bin again, "I've heard many professors mention you, you are a good seedling, you have to continue to work hard." ”

"I will, I will." Wu Bin nodded vigorously.

At this time, Gong Chengwei, who was standing behind Wu Bin, patted Li Yan twice and asked strangely: "This guy is also exaggerated, right?" Did Professor Cheng sponsor him or what? ”

As a physics competition student, Gong Chengwei has of course read three Cheng books, and at the same time admires the depth of knowledge of Professor Cheng Jiafu, who wrote these three books, but he will never exaggerate like Wu Bin......

"I haven't heard of it." Li Yan glanced at Wu Bin, who was trembling with excitement, "This reaction, probably seeing an idol, right?" ”

"Idols?" Gong Chengwei also glanced at Wu Bin, nodded in agreement: "It's a bit of a meaning, and this guy is definitely a fanatic." ”

"Okay, Wu Bin, how long are you going to hold it, and you can't go to class yet?"

After waiting for a while, he found that Wu Bin still didn't mean to let go, so Lu Zhi had to drink lowly.

"Oh, got it."

After hearing this, Wu Bin let go of Cheng Jiafu's hand and slowly retreated.

Then under Lu Zhi's introduction, the students knew that these two introductions were here to teach them the four major mechanics, although they had obviously heard of the competition before, they didn't know how to use the four, but no one would open their mouths to ask this kind of question now, after all, they came to this training camp just to learn new things.

The teacher for the first class was Professor Shu Yousheng, who wrote four words on the blackboard before the class.

【Beyond Measure】

Then ask the students below, "Does anyone know why I wrote these four words?" ”

The students below looked at each other, what is this for, come up and give a dismount first, saying that they are not self-sufficient to learn the four major ones now?

Looking at the inexplicable appearance of his classmates, Shu Yousheng's expression felt like he had succeeded in his scheme, and then turned around and crossed an equal sign after the four words [self-sufficient], and wrote another line of words.

[Don't teach yourself quantum mechanics]

The students below were stunned for a moment after reading it, and then burst into laughter.

Everyone never expected that this old professor would be so humorous.

And the content of Professor Shu Yousheng's lecture is also interesting, explaining the topological insulator and spherical harmonic function that will make most people's eggs hurt very clearly, so that the students respect this professor more and more.

In the third lesson, Professor Jiafu came to teach them about thermodynamics, that is, thermodynamics and statistical mechanics.

At present, Wu Bin has a considerable degree of understanding of the four major mechanics, and he believes that the most difficult of them is this thermal system.

Because he thinks that this thermosystem is more abstract than most people find the most difficult quantum mechanics.

【Entropy】

Professor Cheng Jiafu first wrote this word on the blackboard.

"Statistical mechanics starts with entropy, not temperature."

After starting with this sentence, Professor Cheng Jiafu spent a whole class telling the students the reasons for learning this way, and after doing so, they can explain many questions, such as why the rotation system is hot.

I don't know if it's because of the idol bonus, Wu Bin listens to Cheng Jiafu's class and has a lot of brain cells, and even takes a lot of notes.

This state of euphoria lasted for a week, until the four major mechanics and solid state physics were gradually finished.

And not only Wu Bin, the other students also have an unusually high head-up rate when these two professors give lectures, unlike at the beginning, when some people like to listen to lectures during class, and some like to bury their heads in reading.

Of course, even in such an elite class, there are still a lot of people who listen to it......

For example, Lin Ziqi is one of them, she came to Wu Bin for help when she heard about it on the third day, and coincidentally, like Wu Bin, she also felt that Retong was the most difficult, and she was about to torture her.

"Ah~ I feel like I'm going to die." Lin Ziqi, who finished the question with the help of Wu Bin, spread out on the table.

Wu Bin looked at her and smiled: "Actually, there is one thing about statistical mechanics that is quite friendly, that is, everything can be deduced as long as the most basic equal probability assumptions are used. ”

After Zhao Kehan heard this sentence in the back, he couldn't help but complain, "Come on, it's all from Jingbei to Seattle, and the horse is deduced." ”

"Tsk, that's because you don't love it deep enough." Wu Bin shook his head at him.

At this time, Gong Chengwei on the side also raised his head and said: "Yes, I also think that statistical mechanics is quite friendly, and even Professor Tsung-Dao Lee thinks that statistical physics is one of the most perfect subjects in theoretical physics, because its basic assumptions are simple, but its applications are extremely wide."

"Lazy and you two demon theories." Zhao Kehan raised a middle finger at the two of them and then slipped out to rest.
