Chapter 209: From physics to economy

Xu Mang’s arrival was a devastating blow to this economics professor. He encountered someone sleeping in his class for the first time, and he even wondered for a few times whether the content of his lecture was too boring?
　　 However...
　　 This idea was quickly discarded by the professor, because among the nearly two hundred students, only one is sleeping, which shows that the problem comes from the student himself.
　　 "Ahem!"
　　 "This classmate!" The professor said, "Don't sleep!"
　　"..."
　　"..."
　　"..."
　　 Everyone looked at Xu Mang, but Xu Mang didn't know.
at this time,
　　 The most embarrassing person is Yang Xiaoman. After all, Xu Mang is her boyfriend. After a hurry, he stepped on the back of Xu Mang's instep.
　　 Whoops!
Xu Mang woke up instantly, lying on the table and looking at Xiaoman with a confused expression. 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, just like watching a monkey. ..
　　 "What is your name, this classmate?" the professor asked.
"I?"
　　 "Professor, are you asking me?" Xu Mang looked curious: "Xu Mang... from the Department of Physics, majoring in theoretical physics."
　　Physics?
　　How could the physics department appear here?
Professor 　　 looked at Xu Mang in surprise: "How come the physics department is in the economics department? Classmate...Did you go wrong?"
Uh?
　　 is not right...The physics department is in another campus.
of course,
　　Professor may not know why Xu Mang appeared, and all the students here know why a physics student is in economics class, isn't it because the girl next to him is from the economics department.
"I... this... 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 is stable and stable. He has the ability to mutate. I personally think it's a bit similar to the economy, so come over and listen."
　　 "???"
　　 "???"
　　 "???"
　　What the hell?
　　What strange attractor?
　　 Is this guy crazy?
　　 Most of the students present were bewildered, they were very vague about the mathematical concept proposed by Xu Mang, or even completely ignorant.
Although Professor 　　 didn't know any strange attractors, he was attracted by Xu Mang's next sentence. He was stable and capable of mutation.
　　 "Since it's an observer, please listen carefully and don't sleep." The professor glanced at Xu Mang and continued the class.
　　 escaped!
so close.
　　 Xu Mang knows that many boys present want to put themselves to death, especially those Xiaoman’s suitors, but unfortunately... Besides pretending to be slapped face, I also have a special skill, called catching fish in troubled waters and crossing the sea.
　　 this is not,
　　 Smooth through the difficulties!
"Ugh?"
　　 "What strange attractor you just mentioned...is it linked to the economy?" Yang Xiaoman asked curiously.
"how could I know?"
　　 "This is just a mathematical model of chaos. Anyway, everyone doesn't know when I bring it up. I just play it..." Xu Mang smiled and said, "Am I smart? This made me pass."
moron...
　　 I thought I had a talent for economics.
　　 Yang Xiaoman is a little disappointed. If this guy is really talented in economics, he must be tricked from the physics department to the economics department and come over to accompany him.
　　 What a pity...
　　He has no talent.
Since being named, Xu Mang has been honest a lot. Sitting there playing on his mobile phone, although the economics skills were triggered, Xu Mang didn’t want to learn economics at all, mainly because it felt useless... if he had to learn, Then think about the economy from a physical point of view.
　　 Say it...
　　 Can the two be combined?
　　 Xu Mang pondered this question for a while, then glanced at Xiaoman next to him, as if he could really combine.
　　 I studied physics,
　　 Xiaoman studies economics,
　　 By this time next year, we will almost be able to combine.
　　 Whoops,
　　What am I thinking? !
　　 Hastily decontaminated his thoughts, Xu Mang began to think about economics from a physical point of view.
　　 such as...
　　The degree of freedom of the market economy.
How free can 　　 be?
　　 "Little Man?"
"Uh?"
　　 "The market economy described in neoclassical economics, what free choice, what rational people... is this all fake?" Xu Mang asked curiously.
　　 "Why are you asking this?" Yang Xiaoman gave a blank look.
　　 "Then what..."
"The simplest model in our physics is called a free particle. There are six degrees of freedom. Is this free enough?" Xu Mang said: "For another example... our most idealized model is called gas. There is no interaction, no friction, free movement."
　　 "The problem is here!"
"I found a lot of economists, especially economists on the Internet, what freedom do they advocate... But from a physical point of view, the concept of economy is no longer free now. If freedom... It will become gas." Xu Mang said solemnly.
　　 Yang Xiaoman gave a white glance and said angrily: "You are so annoying!"
　　 Xu Mang: 囧
　　 "Little Man?"
　　 "What are you doing again?!"
"Then let's discuss the issue of market freedom from another angle." Xu Mang said: "I personally think that under the current social structure, the division of labor is continuously refined and organizational capabilities are continuously strengthened. Under this framework, people are free The degree will be less, so market freedom may be a myth compiled by foreigners, which belongs to utopian capital."
　　 Yang Xiaoman was going crazy, and he glared at Xu Mang: "What are you going to do?!"
"I..."
　　 "I'll just talk about it." Xu Mang shrank his head: "Don't take it to your heart, I really just talk about it casually."
"Humph!"
　　 "Shut up to my old lady from now on!" Yang Xiaoman regrets the choice he made. This guy was not like this before... He was quiet at that time, why is he so broken now? Is there too much knowledge?
　　 So annoying.
at the same time,
　　 Xu Mang used his mobile phone to download a classic book by Adam Smith from the Internet.
　　 watched,
　　 Xu Mang found a problem. The name of this book contains rich, but the book does not tell what rich is, but simply quotes Hobbes, rich is the so-called power.
　　 Then,
　　 Xu Mang discovered another problem, the so-called invisible hand in this book.
　　 "Little Man?"
　　 "What are you doing?!"
　　 "The invisible hand is the self-regulation of the market economy, right?" Xu Mang asked.
"Ok."
　　 "What are you looking at?" Yang Xiaoman glanced at his phone curiously, and said helplessly: "Are you planning to study economics?"
"Do not!"
　　 "I'll take a look." After Xu Mang finished speaking, he deleted the book. He felt that the so-called self-regulation seemed...it seemed to be covering up some kind of doctrine behind market competition.
　　What kind of doctrine?
　　 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 ends.
　　 Just as the two were about to leave, the professor suddenly left Xu Mang with him. As Xu Mang’s boyfriend, Yang Xiaoman naturally stood by his side.
　　 "Xu Mang?"
　　 "Your strange attractor was very interesting just now." The professor said, "Can you be more careful?"
"what?"
　　 "I...this..." Xu Mang looked dazed.
　　 Yang Xiaoman stood aside, with a smile on his face, letting you brag, look... let's blow things out.
　　 "Professor..."
"I'll just talk about it casually." Xu Mang straightened his attitude and said respectfully: "For example, a professor, now there is an economic variable that is spinning around. It does not converge to a single point and cannot reach the classical level. Equilibrium in economics, but it will not explode, which will lead to unlimited growth. It just keeps turning and turning and turning..."
　　 "Its dimension is not zero or one, nor two. It is not a whole thing, but a fraction, which is a fractal." Xu Mang said: "This is a very complicated mathematical concept, and I personally feel it is very similar to economics."
　　 "Professor..."
　　 "I haven't studied economics, don't forget these words of mine." Xu Mang hurriedly said: "I like to brag."
　　 Hearing Xu Mang’s words,
Professor 　　 smiled, shook his head and said: "Everyone has their own opinions, and this so-called strange attractor does meet certain characteristics in economics."
after that,
　　 Xu Mang and Yang Xiaoman left the classroom.
　　On the way to the school cafeteria, Yang Xiaoman glanced at the next to him, and asked silently: "Why didn't you tell the professor the things that harassed me in class?"
　　 "I'm not stupid!" Xu Mang smiled bitterly: "Those are just my simple thoughts. When he hears words, wouldn't I be scolded to death?"
"Humph!"
"You also know?" Yang Xiaoman gave a blank look: "Do you have any idea to transfer to the Department of Economics? Your mathematics is very good, but your financial ability should not be too bad, do you know? The highest credits in our department are mathematics course."
"Oh..."
　　 "I know that the protagonist in the movie "Beautiful Mind" is a mathematician. He won the Nobel Prize in Economics for his game theory." Xu Mang said blankly, "I'll study physics."
　　 "Cut!"
　　 "It's like you can get the Nobel Prize in Economics as long as you study economics." Yang Xiaoman pouted, then hugged Xu Mang's arm and said with a grin: "Go shopping at night?"
"no, sorry!"
　　 "I want to learn physics." Xu Mang shook his head.
"Hey!"
　　 "It's easy for you to lose me like this. Did you see the number of your opponents today?" Yang Xiaoman was very upset. He actually competed with physics for a man.
　　 "I'm really going to be fired... If I am fired, I can only go to the math department." Xu Mang said helplessly, "I don't want to go to the math department..."
　　 Yang Xiaoman made many assumptions about Xu Mang's obsession with studying physics, but none of them fits his current situation. How could a good person suddenly learn physics.
　　 The two dine in the cafeteria. The food is relatively simple, but Xu Mang has found some happiness in simplicity.
　　 Fish-flavored shredded pork, moss pork, sweet and sour pork, braised pork, etc.
　　 Yang Xiaoman is sometimes envious, this guy always eats Hesai, he is not fat.
　　After eating,
　　 was taking a walk on the campus. On the way, I received a call from Director Xia, telling him that the key had been given to the security staff at the school gate and asked him to pick it up.
"what?"
　　 "You live in the laboratory?" Yang Xiaoman heard Xu Mang's words ~EbookFREE.me~ and looked at him with surprise: "So miserable?"
　　 "School beds are tight."
　　 "No way." Xu Mang sighed.
　　 Yang Xiaoman had an idea, and said maliciously: "Or...or should I accompany you?"
what?
　　 There is this kind of operation?
　　 Xu Mang looked at Yang Xiaoman in surprise: "Are you crazy?"
　　 Yang Xiaoman gave a white glance: "Coward!"
　　 "This is not a question of timidity." Xu Mang was speechless: "This is a moral bottom line issue. Do you understand if you want to go to jail?"
"moron!"
　　...
　　夜,
　　 is always so peaceful.
　　 In the laboratory, Xu Mang was not sleeping, but was playing around with the computer. There were no other things here, only the computer.
　　 In the previous two hours, Xu Mang was visiting the school forum and found a lot of posts. These posts have a certain pattern, which is to criticize a physics student who came to listen in this afternoon in the economics department.
　　 But a closer look reveals that the core idea is to criticize unfair competition across platforms and regions.
　　 don’t look at it,
　　 This must be issued by a graduate student in the Department of Economics!
