Chapter 220

Xu Mang's arrival was a devastating blow to this economics professor. For the first time, he met someone sleeping in his class, and even doubted for several times whether his lecture content was too boring?

However...

the idea was quickly abandoned by the professor, because only one of the nearly 200 students was sleeping, which showed that the problem was from the student himself.

"Cough!"

"This classmate!" The professor said, "don't sleep!"

"..."

"..."

"..."

"..."

everyone looked at Xu Mang, but Xu mang did not know.

At this time,

the most embarrassing thing is Yang Xiaoman. After all, Xu mang is her boyfriend. In a hurry, she steps on Xu Mang's instep.

Ouch!

Xu mang suddenly wakes up, lies on the table and looks at Xiaoman with a confused face. Seeing her expressionless face, he is about to ask. Then he finds that all the teachers and students in the classroom are staring at themselves, just like looking at a monkey...

"what's your name, classmate?" Asked the professor.

"Me?"

"Professor, are you asking me?" Xu mang looks curious: "Xu mang... Comes from the theoretical physics major of physics department."

Physics?

How did the physics department show up here?

The professor looked at Xu Mang in surprise: "how can physics department be in the class of economics department? Classmate... Are you wrong? "

Eh?

It's not... The physics department is on other campuses.

Of course,

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

"I... this... I want to think about a physical and mathematical problem from the perspective of economics." Xu mang began to lie: "this problem is called strange attractor. It has stability and mutation ability. I feel that it is similar to economy, so I come here to listen."

“？？？”

“？？？”

“？？？”

What?

What strange attractor?

Is this guy crazy?

The vast majority of the students present were confused, and they were very vague about the mathematical concepts put forward by Xu Mang, or even did not know them at all.

Although the professor did not know what strange attractor, but he was attracted by Xu Mang's following sentence, with stability and mutation ability at the same time.

"Since it belongs to the audience, it's good to listen. Don't sleep." The professor glanced at Xu Mang and continued his class.

We've survived!

It's close.

Xu mang knows that many of the boys here want to kill themselves, especially those who pursue Xiaoman. Unfortunately, in addition to pretending to be forced to slap the face, I also have a special skill called fishing in troubled waters to hide from the sky and the sea.

This is not,

to get through the difficulties!

"Ah?"

"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, I put it forward, we don't know, just let me blow it..." Xu mang said with a smile: "am I smart? It's all for me to get through. "

Idiots...

think they have the talent of economics.

Yang Xiaoman is a little disappointed. If this guy really has the talent of economics, he must be cheated from physics department to economics department and come to accompany him.

Unfortunately...

he has no talent.

Since he was named, Xu mang has been quite honest. Sitting there playing with his mobile phone has triggered his economic skills, but he doesn't want to learn economics at all. The main reason is that he feels useless. If he has to learn, he should also think about economy from the perspective of physics.

In other words...

can the two be combined?

Xu mang thought about this problem for a while, and then glanced at Xiao man around him. It seemed that he could really combine.

He is a student of physics,

Xiaoman is a student of economics,

by this time next year, we will be able to combine.

Ouch,

What am I thinking?!

In a hurry to decontaminate his thoughts, Xu mang began to think about economics from a physical point of view.

For example...

the degree of freedom of the market economy.

How free is it?

"Little man?"

"Eh?"

"The market economy described in neoclassical economics, what kind of free choice, what rational people... Are these all false?" Xu asked curiously."Why do you ask this?" Yang Xiaoman has a white eye.

"So what..."

"the simplest model in our physics is called free particle, which has six degrees of freedom. Is this enough freedom?" "For another example, our most ideal model is called gas. All the particles have no interaction, no friction and free movement," Xu said

"Here comes the question!"

"I find that many economists, especially those on the Internet, advocate freedom... But from my physical point of view, the concept of economy is no longer freedom, if freedom... Will become gas." Xu mang said solemnly.

Yang Xiaoman gave a white eye and said angrily, "you are bored!"

Xu Mang: Xiaoman

"What are you doing?"

"Let's start from another angle and discuss the issue of market freedom." "I personally believe that under the current social structure, with the division of labor being refined and the organizational capacity being strengthened, people will have less freedom under this framework. Therefore, market freedom may be a myth compiled by foreigners, belonging to Utopian capital theory," Xu said

Yang Xiaoman is going crazy and stares at Xu Mang: "what are you going to do?"

"I..."

"I'll just talk about it." Xu mang shrunk his head: "do not go to heart, I really just casually talk about."

"Hum!"

"From now on, shut up for me!" Yang Xiaoman regretted the choice he made. This guy was not like this before. At that time, he was quiet. How could he be so broken? Did you learn too much knowledge?

How annoying.

At the same time,

Xu mang downloaded a classic book of Adam Smith on the Internet with his mobile phone.

Looking at it,

Xu mang found a problem. The name of the book is rich, but the book does not tell what the rich is, but simply quotes Hobbes' words, that is, the so-called power.

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

"Little man?"

"What are you doing?"

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

"Well."

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

"No!"

"I'll look around." After Xu mang finished, he deleted the book. He felt that the so-called self-regulation seemed to cover up some kind of doctrine behind the market competition.

What doctrine?

Xu mang does not know about this problem for the time being, but vaguely feels that it is related to power competition.

Soon,

Xu Mang's audit tour ended.

When they were ready to leave, the professor suddenly left Xu mang behind. As Xu Mang's girlfriend, Yang Xiaoman naturally stood beside him.

"Xu mang?"

"Your strange attractor was interesting." The professor said, "can you speak more carefully?"

"Ah?"

"I... this..." Xu mang looks confused.

Yang Xiaoman stands aside with a smile on his face. Let's brag. See... Blow things out.

"Professor..."

"I'll just say it casually." Xu mang straightened out his attitude and said respectfully: "for example, Professor, there is an economic variable that is rotating in a circle. It does not converge at a point and can not reach the equilibrium in classical economics, but it will not explode, which will lead to infinite growth. It will go straight and round..."

"its dimension is not zero, it is not one, it is not two, it is not an integer It's a fraction. It's a fractal. " "It's a very complicated mathematical concept, and I personally feel like the economy," Xu said

"Professor..."

"I haven't studied economics, so don't forget these words." Xu mang said in a hurry: "I like to boast."

Hearing Xu Mang's words,

the professor laughed, shook his head and said, "everyone has his own point of view, and this so-called strange attractor really conforms to some characteristics of economics."

After that, Xu Mang and Yang Xiaoman left the classroom.

On the way to the school dining room, Yang Xiaoman glanced at the asshole around him and asked quietly, "why didn't you tell the professor those words that harassed me in class?"

"I'm not stupid!" Xu mang said with a wry smile: "those are just my simple thoughts. When he hears them, are they not scolded to death?"

"Hum!"

"You know that, too?" Yang Xiaoman gave a glance: "do you have any idea to transfer to the Department of economics? You're good at math, and your economic ability should not be too bad, you know? The highest credit in our department is mathematics. ""Oh..."

"well, I know that the main character in the movie" beautiful heart "is a mathematician, and his game theory won the Nobel Prize in economics." "I'd better study physics," said Xu mang without expression

"Cut!"

"It's like you can get the Nobel Prize in economics as long as you study economics." Yang Xiaoman Dudu mouth, and then holding Xu Mang's arm, said with a smile: "go shopping at night?"

"No way

"Learn physics." Xu shook his head blankly.

"Hello

"It's easy for you to lose me like this. Do you see the number of your opponents today?" Yang Xiaoman is very unhappy. He competes with physics for a man.

"I'm really going to be expelled... If I'm opened, I'll have to go to the math department." Xu mang helplessly said: "I don't want to go to the mathematics department..."

for Xu Mang's persistent study of physics, Yang Xiaoman has made a lot of assumptions, but none of them is in line with his current situation. How can a good person suddenly study physics.

Two people in the dining hall, the meal is relatively simple, but Xu Mang in the simple to seek some happiness.

Fish flavored shredded meat, Muxu meat, sweet and sour sirloin, braised pork and so on.

Yang Xiaoman is envious sometimes. This guy always eats haisai, but he is not so fat.

After dinner,

after a walk in the campus, I received a phone call from director Xia, informing him that the key had been given to the security personnel at the gate of the school and asked him to pick it up by himself.

"What?"

"You live in the lab?" After hearing Xu Mang's words, Yang Xiaoman looked at him in surprise: "so miserable?"

"School beds are tight."

"No way." Xu sighed blankly.

Yang Xiaoman had a brainwave and said with malice: "or... Or I will accompany you?"

Huh?

And this kind of operation?

Xu mang looked at Yang Xiaoman in surprise: "crazy?"

Yang Xiaoman a white eye: "coward!"

"It's not a matter of timidity." Xu mang was speechless: "this is the bottom line of morality. Do you understand it if you want to go to prison?"

"Idiot!"

...

night,

is always quiet.

Xu is playing computer in the lab. there are no other things in the lab.

In the past two hours, Xu mang was visiting the school forum, and then he found many posts. These posts have some rules, that is, they are criticizing a physics student who came to visit the economics department's class this afternoon.

However, we can find that the core idea is to criticize the cross platform and cross regional unfair competition.

Needless to say,

it must have been issued by a graduate student in the Department of economics!
