Xu Mang's arrival was devastating for the economics professor, who for the first time encountered someone sleeping in his class, and even wondered a few times if the content of his lecture was too boring.

However...

The idea was quickly abandoned by the professor, who was alone in his sleep of nearly 200 students, suggesting that the problem was with the student himself.

"Ahem!"

"This classmate!" said the professor, "Don't sleep!"

“...”

“...”

“...”

Everyone looked at Xu Mang, but Xu Mang didn't know.

At this point,

The most embarrassing thing is Yang Xiaoman, after all, Xu Mang is her boyfriend, and in a hurry, she stepped on Xu Mang's instep.

Oops!

Xu Mang came to his senses in an instant, lying on the table and looking at Xiao Man with a confused face, seeing her expressionless face, he was about to ask, and then found that the teachers and students in the entire classroom were staring at him, like looking at monkeys...

"What's your name?" the professor asked.

"Me?"

"Professor, are you asking me?" Xu Mang looked curious: "Xu Mang... Theoretical Physics from the Department of Physics. ”

Physics?

How did the physics department end up here?

The professor looked at Xu Mang in surprise: "How can someone from the Department of Physics be in a class in the Department of Economics? Are you on the wrong track?"

Belch?

It's not right either... The Department of Physics is on other campuses.

Of course

The professor may not know the reason for Xu Mang's appearance, but all the students here know that the reason why a physics student is in the economics class is not that the girl next to him is from the economics department.

"I... This one... I want to think about a certain physics and mathematics problem from the perspective of economics. Xu Mang began to open his eyes and talk nonsense: "This problem is called a strange attractor, and it has stability and the ability to mutate, and I personally think it is a bit similar to the economy, so I came to listen to it." ”

“？？？”

“？？？”

“？？？”

What's that?

What strange attractors?

Is this guy crazy?

Most of the students present were confused, and they were very vague about the mathematical concepts proposed by Xu Mang, or even knew anything about them.

Although the professor didn't know what strange attractors were, he was attracted by Xu Mang's later sentence, which had stability and mutation ability at the same time.

"Since it's an auditor, listen well and don't sleep. The professor glanced at Xu Mang and continued to start the class.

Escape!

It's dangerous.

Xu Mang knew that many of the boys present wanted to put themselves to death, especially those of Xiao Man's suitors, but unfortunately... In addition to pretending to be forced to slap my face, I also have a special skill called fishing in troubled waters.

It's not,

Survive the storm!

"Huh?"

"What strange attractor you just said... Is it linked to the economy?" Yang Xiaoman asked curiously.

"How do I know?"

"It's just a mathematical model of chaos, anyway, everyone doesn't know if I put it up, whatever I want..."Xu Mang said with a smile: "Am I smart? ”

Idiot...

I thought I had a talent for economics.

Yang Xiaoman was a little disappointed, if this guy really had a talent for economics, he must be deceived from the physics department to the economics department and come over to accompany him.

Pity...

He has no talent.

Since being named, Xu Mang has been a lot more honest, sitting there playing with his mobile phone, although he has triggered his economics skills, Xu Mang doesn't want to study economics at all, mainly because he feels useless... If you have to learn, then you should also think about economics from a physical point of view.

Saying...

Can the two be combined?

Xu Mang thought about this question for a while, and then glanced at Xiao Man beside him, and it seemed that he could really combine.

I studied physics myself,

Xiao Man is studying economics,

By this time next year, it will almost be able to combine.

Oops,

What was I thinking?!

Hurriedly decontaminating his thoughts, Xu Mang began to think about considering economic problems from a physical point of view.

Like what...

The degree of freedom of the market economy.

How much freedom can you have?

"Xiao Man?"

"Huh?"

"The market economy described in neoclassical economics, what free choice, what rational man... Is this all fake?" asked Xu Mang curiously.

"Why are you asking this?" Yang Xiaoman glanced at him.

"What..."

"The simplest model in our physics is called a free particle, there are six degrees of freedom, this is enough freedom, right?" Xu Mang said. Our most idealistic model is called a gas, where all the particles have no interaction with each other, no friction, and are free to move. ”

"Here's the problem!"

"I've found a lot of economists, especially economists on the Internet, who advocate freedom... But from a physical point of view, the concept of economy is no longer freedom, and if freedom... It will turn into gas. Xu Mang said seriously.

Yang Xiaoman glanced at him and said angrily: "You are so annoying!"

Xu Mang: Embarrassed

"Xiao Man?"

"What are you doing again?!"

"Let's look at the issue of market freedom from another angle. Xu Mang said: "I personally believe that under the current social structure, the division of labor is constantly refined, the organizational ability is constantly strengthened, and people will have less freedom under this framework, so market freedom may be a myth of foreigners, which belongs to utopian capital." ”

Yang Xiaoman was going crazy, and glared at Xu Mang: "What are you going to do?!"

"I..."

"I'll just say it. Xu Mang shrank his head: "Don't take it to heart, I'm really just talking casually." ”

"Humph!"

"Shut up to my mother from now on!" Yang Xiaoman regretted the choice he made, this guy wasn't like this before... He was quiet then, but now why is he so broken-mouthed? Is it because he has learned too much?

It's annoying.

meanwhile

Xu Mang used his mobile phone to download a copy of Adam Smith's classic book on the Internet.

Look at it,

Xu Mang found a problem, the name of the book has wealth, but the book does not tell what wealth is, but simply quotes Hobbes's words, wealth is the so-called power.

subsequently

Xu Mang found another problem, the so-called invisible hand in this book.

"Xiao Man?"

"What are you doing?!"

"The invisible hand is the self-regulation of the market economy, right?" asked Xu Mang.

"Hmm. ”

"What are you looking at?" Yang Xiaoman glanced at his mobile phone curiously, and said helplessly: "Are you going to study economics?"

"No!"

"I'll take a casual look. After Xu Mang finished speaking, he deleted the book, and he felt that the so-called self-regulation seemed to be... It seems to be hiding a certain ismism behind market competition.

Whatism?

Xu Mang didn't know this question for the time being, but he vaguely felt that it was related to power competition.

soon

Xu Mang's audit tour ended.

Just as the two were about to leave, the professor suddenly left Xu Mang behind, and Yang Xiaoman, who was Xu Mang's boyfriend, naturally stood by his side.

"Xu Mang?"

"Your weird attractor just now was interesting. The professor said, "Can you be more careful?"

"Huh?"

"I... This..."Xu Mang looked confused.

Yang Xiaoman stood on the side, with a smile on his face, let you brag, look... Let's blow things out.

"Professor..."

"I'll just say it. Xu Mang corrected his attitude and said respectfully: "For example, professor, there is an economic variable that is spinning in a circle, it does not converge at a point, it cannot reach the equilibrium in classical economics, but it will not explode, which will lead to infinite growth, and it will keep turning and turning..."

"Its dimensionality is not zero, not one, not two, not the whole thing, but a fraction, which is a fractal. "This is a very complex mathematical concept, and I personally feel that it is very similar to the economy. ”

"Professor..."

"I didn't study economics, so don't forget these words of mine. Xu Mang hurriedly said: "I like to brag. ”

Hearing Xu Mang's words,

The professor smiled, shook his head, and said, "Everyone has their own opinions, and this so-called strange attractor does fit some characteristics of economics. ”

afterwards

Xu Mang and Yang Xiaoman left the classroom.

On the way to the school cafeteria, Yang Xiaoman glanced at the bastard beside him and asked silently, "Why didn't you tell the professor those words that harassed me during class?"

"I'm not stupid!" Xu Mang smiled bitterly: "Those are just my simple thoughts, and when he hears it, won't he be scolded to death?"

"Humph!"

"Do you know?" Yang Xiaoman glanced at him: "Do you have any idea to transfer to the Department of Economics?" Your math is very good, and your economic ability should not be too bad, do you know? ”

"Oh..."

"I know this, the protagonist of the movie "A Beautiful Mind" is a mathematician, and his game theory won the Nobel Prize in Economics. Xu Mang said expressionlessly: "I'll study physics." ”

"Cut!"

"It's like you can win the Nobel Prize in Economics just by studying economics. Yang Xiaoman pouted, then hugged Xu Mang's arm, and said with a smile: "Go shopping at night?"

"No!"

"You have to study physics. Xu Mang shook his head.

"Hey!"

"It's easy for you to lose me, and you also saw the number of your opponents today, right?" Yang Xiaoman was very unhappy, he actually competed with physics for a man.

"I'm really going to be expelled... If you are fired, you can only go to the mathematics department. Xu Mang said helplessly: "I don't want to go to the mathematics department..."

For Xu Mang's insistence on learning physics, Yang Xiaoman has made many, many assumptions, but none of them meet his current situation, how can a good person suddenly learn physics.

The two ate in the cafeteria, and the meal was relatively simple, but Xu Mang found some happiness in the simplicity.

Fish-flavored shredded pork, mushu pork, sweet and sour tenderloin, braised pork and so on.

Yang Xiaoman is sometimes very envious, this guy always eats seas, but he is not very fat.

After eating,

Walking around the campus, I received a phone call on the way, which was from Director Xia, who informed him that the key was given to the security personnel at the school gate and asked him to pick it up himself.

"What?"

"You live in the laboratory?" Yang Xiaoman looked at him in surprise after hearing Xu Mang's words: "So miserable?"

"School beds are tight. ”

"No way. Xu Mang sighed.

Yang Xiaoman had an idea, and said with bad intentions: "Or... Why don't I stay with you?"

Ha?

And this kind of operation?

Xu Mang looked at Yang Xiaoman in surprise: "Crazy, right?"

Yang Xiaoman glanced blankly: "Coward!"

"It's not a matter of timidity. Xu Mang was speechless: "This is a moral bottom line issue, do you understand if you want to go to prison?"

"Idiot!"

...

night

Always so peaceful.

In the laboratory, Xu Mang did not sleep, but was tinkering with the computer, there was nothing else here, only the computer.

In the previous two hours, Xu Mang was visiting the school forum, and then he found a lot of posts, and these posts had a certain pattern, that is, they were attacking a physics student who came to audit the big class of economics this afternoon.

But a closer look reveals that the core idea is to criticize unfair competition across platforms and regions.

No need to look,

This must have been sent by a graduate student in the Department of Economics!
