Xueba, I beg you to go and escort him quickly!

As he said that, Xu Heng took the pen and was about to do it, but the moment he put the pen down, Xu Heng stopped.

Everyone, "???"

"Why did you stop?"

Xu Heng, "I'm thinking about whether there is a new way of proving..."

Rumble!

Boom! !

Boom! ! !

As soon as these words came out, it was like five thunderbolts!

clap la la...

New idea of ​​proof?

impossible!

how can that be!

Geek!

Everyone looked at each other, especially those math teachers, this is impossible... this is impossible... this should be impossible... absolutely impossible!

"Student Xu Heng, you know you are..."

Luo Yingnan reminded Xu Heng, but Xu Heng kept his head down in thought, without even looking at them.

"This……?!"

After a while, suddenly, Xu Heng murmured, "Strictly speaking, whether 1 is equal to a cycle or not requires more conditions to be judged."

"What you said and what I said both represent a basic sequence of rational numbers, so the two belong to the same equivalence class and correspond to the same real number."

"In this case... change the direction..."

"It should be fine!"

Suddenly, Xu Heng raised his head, looked at the crowd, and smiled slightly.

"Teachers, have you heard of the power sequence theory?"

For a moment, everyone was stunned.

"???"

Seeing their blank faces, Xu Heng said, "All right... let me explain in detail."

"In this theory, 1 and cycle represent different subsets of integers. It can be proved that the former is strictly greater than the latter, and the two have the same properties in some occasions."

"It can also be replaced by each other."

"When humans or computers deal with the approximate calculation of real numbers, they will not first construct a rational number basic sequence or Dedekind segmentation, but directly process a finite sequence of integers. The intuitive inference of this processing method is that 1 is greater than the cycle .”

"The power order theory can strictly prove that there is an algebraic system larger than the real number field to satisfy this conclusion, and the real number field is the sub-algebraic structure of the algebraic system. In this sense, the power order theory is to reveal the difference between 1 and cycles and The best theory of connection.”

"..."

This time, Xu Heng tried his best to speak fully.

This group of teachers scratched their heads and couldn't understand at all.

They all turned their attention to Luo Yingnan and the math teachers, but they also frowned, not knowing what to do for a while.

It was too obscure.

"Student Xu Heng, wait a moment...you let us sort it out...thank you...｀ ~..."

They looked at each other many times, pondering again and again.

In the end, Xu Heng was allowed to continue.

Xu Heng wrote down on the paper:

A well-ordered set [L, <] is called an almost well-ordered set.

If any x∈L is given, [L≥x, <] is a good order.

Coincidentally, the set of integers Z is an almost well-ordered set.

Xu Heng, "Actually, this is not a coincidence. We define an almost well-ordered set based on the properties of the integer set. Use..."

Luo Yingnan and the teachers showed embarrassment, "Student Xu Heng, please wait a little longer, can you?"

"We...we..."

again and again!

They interrupted Xu Heng again and again.

Xu Heng also frowned slightly.

He looked at these teachers and he knew he was overestimating their knowledge base.

In front of them, Luo Yingnan's math teachers are just like the teachers of other subjects, staring at each other.

They have never been exposed to this aspect of knowledge.

Although what Xu Heng said also belongs to mathematics, but... far beyond their cognition.

Talk and listen.

Xu Heng, "It is a dense and complete linear continuum. It can be proved that this thing is isomorphic to the classic positive real numbers and isomorphic to the infinite binary decimal system. And the infinite binary decimals do not include finite non-zero numbers like 1. . Convert binary to decimal, and you have..."

Luo Yingnan, "I have a question..."

"There is still a problem..."

"Excuse me!"

"here……"

Xu Heng seemed to be a teacher, and they seemed to be students.

When Xu Heng finished speaking, he felt as if he had gotten into a fight.

very tired.

"So, teachers, do you understand?"

"If you don't understand, I really have nothing to do!"

"I can't be more detailed than I said!"

"I think this way of thinking is much simpler than before! Isn't it too forgiving?"

"In addition, this idea, as long as you understand the theory inside, it will be fine."

"You are all teachers, and you have researched whether the cycle is equal to 1. You must not only care about class and get out of class, but also have teachers who deal with academic issues..."

When Xu Heng said that, many teachers blushed and lowered their heads.

This……

Everyone is sorry!

I am very sorry!

It's so embarrassing.

Xu Heng got up slowly, "If there's nothing else, I'll leave first? Teachers?"

At the moment when everyone was stunned, Xu Heng left the meeting room, and then...

Instead of going back to class, he came to the principal's office.

The headmaster looked confused, "???"

"Xu Heng, why did you come to my place?"

"???"

"This... Xu Heng, what's your situation?"

Xu Heng sat down, and the headmaster immediately poured tea.

"call……"

Xu Heng sighed, "It's been a whole morning, surrounded by a group of teachers, it's too uncomfortable, come here to relax."

The principal's face darkened.

"Forehead……"

Xu Heng glanced at the principal, "Don't tell them I'm with you, shh..."

headmaster,"!!!"

"This...isn't that bad?"

Xu Heng, "What's wrong? They came to listen to the lectures, not to look for me, really..."

"Besides, I won't talk about it when I ask things. The point is that they still don't understand after I explain it. My mouth is dry."

headmaster,"???"

"Did these teachers ask you questions? The point is that they still don't understand...?"

Xu Heng spread his hands, "Yes."

Principal, "Puff——"

"It shouldn't be, they are all teachers with academic research!"

Xu Heng, "Hey...don't mention it!"

"Stop talking about this, don't talk about this."

Xu Heng got up and came to the computer.

"Principal, do you need it?"

Principal, "No!"

Xu Heng smiled, "I'll play two."

Nima...

!!!

Xu Heng, are you serious?

Your class is being attended by representatives of 24 schools across the province, but you come to my place to play games?

At the same time, the teachers in the conference room came back to their senses one by one.

"Student Xu Heng?"

"Student Xu Heng doesn't seem to be here..."

"Where did it go?"

"Go back to class?"

"Go back and see!"

When all the teachers found the class one by one, the chemistry teacher's heart trembled.

He is excited!

He didn't expect these teachers to appear suddenly.

Could it be that something was delayed before?

But that's okay, luckily you're all here!

But it hadn't been three seconds before his "forgiveness" sprouted in his heart. When the group of teachers saw that there was no Xu Heng in the last row, they were all stunned.

Then, you look at me, I look at you.

"He's not in class?"

"This……"

"Where are you going?"
