"The essence of the universe is a vacuum zero. If it is an energy, there will be energy. If it is an energy, there will be radiation diffraction..."

"Star energy is also a kind of energy, but it is different from conventional energy. It has unique qualities..."

"Look at this example, use the differential form of momentum theorem: fdt=mdv=d(mv)f=ma=m(dv/dt), you can take the lead in finding..."

In fact, the course of Introduction to Star Energy is very difficult because it is an alternative and profound scientific system that ordinary people have never been exposed to.

There are significant differences between the logic and understanding methods and the traditional knowledge system on earth.

Even if Su Ye can see that the editors of the textbook try to use the Earth's knowledge system to interpret star energy, the huge gap in civilization level actually leads to a problem.

That is, question a is explained by traditional knowledge, but question b has to be answered using the scientific system of the mechanical civilization of Gashu.

In this way, both sides are not pleased, which will increase the difficulty of this course.

Therefore, it is easy for beginners to learn this course for the first time.

Especially among the students in the class, there are not many students who have preview habits like Su Ye. Therefore, when they looked at the inexplicable formulas and concepts on the blackboard, they all wrote in their hearts:

"?"

The new students were confused and began a repetitive cycle of doubting their lives and doubting themselves.

Who am I, where am I?

What is the teacher talking about?

Why can't I understand?

Some students with poor psychological qualities have begun to express their collapse.

In fact, as a teacher, Jiang Qingying certainly knows this.

But even though she had deliberately slowed down the pace of teaching, the difficulty of the course itself was here, and she had no better way.

However, unlike everyone, for Su Ye who had already prepared in advance, it was not that difficult to understand Jiang Qingying's ideas.

Soon, Su Ye and other students in the class formed two different pictures.

Most of the students looked at the blackboard without moving, with a dull look on their faces, which deeply interpreted the vivid image of the poor student.

Student Su Ye took notes while nodding from time to time, looking deeply understanding.

At first glance, he is a top academic master!

At this time, Fang Zhun, who was sitting next to Su Ye, said that he couldn't listen anymore, his mentality was about to explode, and he couldn't wait to find a companion.

So he pushed Su Ye with his elbow and asked softly:

"Yezi, do you... understand?"

Su Ye looked at Fang Zhun, pondered for a moment, and shook his head decisively.

In order to make his friends happy, he chose a lie with kindness.

Knowing that Su Ye was like him, Fang Zhun turned his head with peace of mind and continued to face the destruction of Star Energy Knowledge:

"The essence of star energy is the key and difficult point of this chapter, and it is also a point that is often tested in the exam."

Jiang Qingying paused, turned her eyes to the classmate below and said:

"Take this opportunity to get to know new classmates."

After looking at the list, Jiang Qingying pointed to a name:

"Student Xu Yi, let's talk about your understanding."

Xu Yi is a tall and thin girl with a pair of round-frame glasses and a long ponytail, which has a literary flavor.

Su Ye was worried about this problem for a long time last night, and Xu Yi, who had not previewed it, was naturally confused.

And there is no answer to this question in the book.

So she could only stand up and said with a bitter face:

"Teacher, I... don't know."

Jiang Qingying also expressed her understanding, and did not make things difficult for Xu Yi, nodded and said:

"Then you sit down first and pay attention to the opinions of other students."

Xu Yi nodded, let out a breath, and sat down.

Jiang Qingying said again:

"Who does anyone want to express their opinions on this issue?"

Jiang Qingying also knew that this question was not easy, so she asked a question publicly.

However, wherever Jiang Qingying's eyes reached, the students lowered their heads one after another, looking like "I don't know, don't call me."

Su Ye naturally knew the answer to this question, but he did not take the initiative to answer this question.

He is not a person who likes to show off, nor does he like to actively express his opinions on such occasions.

However, because he knew the answer to the question, he felt confident, so he did not lower his head and pretend to be an ostrich like other classmates.

At this time, Jiang Qingying's eyes happened to patrol Su Ye and noticed the difference between him and other classmates.

In fact, before this, Jiang Qingying had noticed Su Ye.

For a teacher, observing students' learning status in class is a basic skill, and she can see that Su Ye's concentration in class.

Even though the actions during class can be disguised, the clearness in the eyes cannot deceive people.

Therefore, Jiang Qingying's eyes finally fell on Su Ye after looking around:

"Come on, this classmate, what's your name?"

Su Ye slowly stood up and said his name to Jiang Qingying:

"Su Ye."

At this moment, the eyes of the whole class were gathering on him.

Jiang Qingying nodded, she had a deep impression of Su Ye:

"Let's talk about your opinion from the question just now."

Su Ye thought for a moment.

Although he had thought about this issue yesterday, the complexity of the issue itself still requires him to organize the language.

Seeing the encouragement in Jiang Qingying's eyes, Su Ye looked calm and said slowly:

"First of all, star energy itself is an energy, but it is different from the kinetic energy, heat energy or potential energy we are familiar with, and has its own particularity."

Su Ye’s clear voice sounded in the classroom:

"Since the possibility of dispersion of moving objects is much more than the possibility of aggregation, the energy must be divergent, that is, it must obey the second law of thermodynamics - the law of entropy increase."

"Entropy is used to measure the degree of chaos of a system. When a system is more orderly, its entropy is smaller, and when the system is more disorderly, its entropy is larger."

"The process of entropy increase is irreversible, that is, in an isolated system, the system will eventually reach an isolated and disordered state..."

As Su Ye talked casually, the atmosphere in the classroom gradually became quieter.

In fact, what Su Ye talked about was the scope they were going to learn, but this question appeared in the textbook by thinking about questions. There were only questions in the book, but no answers, and the teacher needed supplements.

The original intention of Jiang Qingying's question was just to take this opportunity to understand everyone and listen to their classmates' ideas, and there was no hope that they would give a definite answer.

But who knew that a freak like Su Ye would appear. Not only did he preview all night before class, he also sought out the knowledge points he had not understood.

No one would have known each other, so no one would be embarrassed.
