Chapter 43 Don’t guess what the girl is thinking

Zhuo Lang tilted his head and looked in the direction where Jiang Xudong's eyes had just straightened.

Not surprisingly, it was the window of the liberal arts base classroom opposite.

"It's broad daylight, Sichun?"

Jiang Xudong suddenly blushed and shook his head quickly, "No way! I was just looking at the curtains and thinking about a philosophical question."

"Yo yo yo~! Third brother, wake up! We are a science class, not a liberal arts class!"

Mark, who came over to eavesdrop, couldn't help laughing.

Jiang Xudong's face turned redder and he pointed at the curtain and said, "Tell me, are the flags moving or the wind moving?"

Zhuo Lang rolled his eyes at him, "The heart of a benevolent person is moved! Damn it, you haven't read it, have you?"

Jiang Xudong shook his head, "I must have heard this story before, and I also know that it is the heart of a benevolent person. But she asked me, from the perspective of a science student, is it the wind that moves, or the flags that move?"

Zhuo Lang hissed and started to look at the curtains in a daze.

Mark glanced at the two of them strangely, "What kind of problem is this? The force of the wind blew the flag, so the two objects interacted with each other and moved together."

"Shut up, you scumbag!" Several math and science bosses in the classroom shouted at the same time.

Mark's eyes widened, feeling a little incredible.

Is this...difficult?

It’s something that all junior high school students know!

Are they collectively playing tricks on me?

But with so many big bosses speaking at the same time, he felt a little scared and began to lose confidence.

Mark looked eager for knowledge, "What's the problem? Isn't this an explanation from physics?"

Zhuo Lang touched his chin, with a confused look on his face, "The problem... is a bit big! What you said is not wrong from the perspective of elementary physics."

Mark rolled his eyes, "Then it's over. Why do you call me a scumbag?"

Wu Jun glared at him, "This is a question that any science student can answer.

But you have to think about it, who is asking the question?

That's Yin Mo! Yin Mo, who is ranked 7th on the school beauty list! The monitor of the liberal arts base class!

How could the question she asked Dongzi be so superficial?"

Mark thought about it and suddenly felt that it made sense!

Any science student can answer this kind of question, so why would you ask Jiang Xudong such a simple question?

There must be a deep meaning in this.

Zhuo Lang thought about it carefully, "What kind of problem is this? Physics can be counted, and mathematics can be counted."

Mark was completely confused, "I don't read much, but I also know that the wind blows and the flags move, it has nothing to do with mathematics!"

Zhou Kun raised the bottom of the beer bottle on the bridge of his nose, his eyes shining with wisdom, "This is related to information theory. Information itself, according to Shannon's definition, is the 'mathematical theory of information dissemination', so it is mathematics.

The question is not surprising."

Mark took a breath when he heard this. He was the strongest math and science guy in the class besides Qing Yun.

However, he said he didn't understand what Zhou Kun was talking about at all.

All the big guys in the classroom were collectively lost in thought.

"Young maknae, what do you think?" Seeing that everyone was at a loss, Zhou Kun shouted from a distance.

At this time, Qing Yun was still talking to Tang Qianying.

After listening patiently to them for a while, Qing Yun was stunned for a while, and then smiled bitterly,

"There are too many possibilities involved here, including field information feedback closed loops, cybernetic categories, uncertainty principles, and observer utility. They can all be discussed, and they all make sense."

Qing Yun scratched his hair. He also felt that this problem was difficult to solve.

Mainly because I don't know how to explain it to them.

These big guys in the classroom are all people who have broken through the limits of elementary physics and are now exposed to and exploring advanced physics.

In fact, this problem has multiple explanations in multiple disciplines.

Qing Yun thought for a while and decided not to complicate things, "For example, from the perspective of information theory proposed by Zhou Kun, let me ask you, what is information?"

Zhou Kun immediately answered, "In Chinese, the word "information" means "communication" and "reception", and "information" means a shrinking pattern, which implies the behavior we are describing.

The two words information put together mean: we are describing and spreading something, and this thing is information to us.

Shannon believed that information is something used to eliminate random uncertainty."

Qing Yun nodded, "Is 'information' matter or energy?"

Zhou Kun was stunned and thought for a while, "It does not belong to matter or energy?"

Qing Yun smiled, "Shannon's definition of information is basically derived from the concept of entropy in thermodynamics.

In thermodynamics, entropy is a measure of the disorder of a system.

According to Shannon, information is when humans find something of value to us among some chaotic possibilities..."

Unknowingly, Qing Yun walked up to the podium as naturally as he did in his previous life, started writing definitions and formulas on the blackboard, and began to deduce.

At this moment, his face was filled with the light of confidence, and his movements were all that of the 38-year-old full professor of chemical physics in his previous life.

Everyone in the classroom suddenly felt in awe. Even the physics teacher Wang Jianjun who had just walked into the classroom felt as if he had returned to a university classroom.

Wang Jianjun did not interrupt Qing Yun's story, but walked to an empty seat, pulled out a chair and sat down.

Some competition students no longer come to school, and there are many empty seats in the classroom.

"Information can be shared, but material resources and energy cannot be shared. If I give you information, I will not lose anything, but I will lose as much as I give you material resources and energy.

This is the most obvious way that information is different from material resources and energy."

The young man on the stage scolded Fang Qiu, while the comics in the audience had cautious eyes.

Tang Qianying said she didn't understand.

But it doesn't stop her from watching her handsome brother perform!

Qin Manman also had a thick smile on his lips.

Daxing's eyes were full of pride, he was proud of him and even more proud of himself.

The man I chose!

So handsome!

But……

With the bright and happy boy in front of him, do I really want him to embark on the path of intrigue and deception in the business world?

“A tree or a river in front of us is a ‘thing’; the growth of the tree and the flow of the river are ‘things’.

I personally believe that "things" are described by our observers' movements of objects. Without us observers, things would not exist, and "things" exist objectively and still exist without us observers.

Wind and flags are objects, and the movement of wind and flags are things.

Then the question comes, things are described by observers, so..."

"I'm here? Things are there? If I'm not there, things aren't there?" Zhou Kun was also stunned.

Jiang Xudong's eyes widened, "So, is it still the heart of the benevolent?"

This conclusion caused an uproar in the audience.

Qing Yun smiled proudly in his heart. As a professor of science who writes to obtain project funds, complicating simple things is an essential skill for him to write papers in the underworld.

Wang Jianjun knocked on the table, "Hey! It's a physics self-study class after all, from the perspective of physics experiments."

Qing Yun was a little embarrassed.

It’s not that I can’t talk about it, but I don’t plan to be reborn and win the Nobel Prize in Physics!

Talk about entanglement?

Depend on!

Even if he follows Zhang Chaoyang's path, he must at least make enough money.

He closed his eyes and thought for a while, then said, "Mr. Wang, just now it was actually in the realm of physics.

So, let me change the direction.

You are standing in a closed and transparent box, and you cannot directly feel whether there is wind outside the box.

You may see the flags moving outside the box, but you cannot be sure whether there is wind or whether the wind causes the flags to move.
