Chapter 729: A Mathematical Model Worth 20 Million

After dinner, night gradually fell.

In Xujia Village, from time to time, some villagers and neighbors are walking and chatting on the spacious cement road, very leisurely.

Of course, more people gathered at Xu's house, chatting or playing cards, or introducing Xu Chuan to a blind date

"Chuanzi, I didn't say it, although you are a big scientist and very busy now, but you are also twenty-six or seventeen years old, you are going to get married, and if you don't get married, your parents will have to wait until when you hold your grandson."

In the living room, several middle-aged women chatted around the electric stove, and one of them looked at Xu Chuan with a smile and opened his mouth to introduce.

"Great scientists, it's normal to have a high vision, but you can't be single all the time. I have a niece in my family who is the same age as you. Although the education is only a bachelor's degree, but the beauty is not worse than the average star, I will be a matchmaker for you, while you are at home during the Chinese New Year, how about the two of them meet? ”

On the sofa, Xu Chuan coped with a helpless smile on his face.

Just after dinner, the person who came to the door to say the matchmaker seemed to have made an appointment, one after another. The key is that these matchmakers are more or less intimate with his family.

It's easy to refuse, but it's not enough to stand up to the crowd.

And more importantly, Mother Xu stood on the matchmaker's side.

Other people's face can be used or not, but Mom, no matter how high his achievements are, he can also cut his scalp and beat him with a broom.

So Xu Chuan could only sit helplessly on the sofa and cope with it with a smile.

At this moment, the mobile phone in his pocket suddenly vibrate, and Xu Chuan took it out and took a look, it was a message from Xu Xiao.

"Brother, do you want to get out of there, I have a way, do you want to listen? (squint)"

Xu Chuan was stunned for a moment, and then quickly typed and replied: "What way?" ”

"Once and for all, I guarantee that there will be no matchmaker coming to your door to say goodbye to you in the future, but you know, hee hee §(* ̄▽ ̄*)§"

The corners of Xu Chuan's mouth twitched, and his face was full of black lines.

Sister Plus Money is here again. It's really a desperate wool grabbing for one of his brothers, right?

But to be honest, he was really moved.

Without him, these matchmakers are really too difficult to deal with, and they make him more emaciated than solving a world-class mathematical problem.

In addition, there is an old mother who wants to hug her grandson now, and when they get together, they all say that a woman is five hundred ducks, and there are thousands of them here, and he would rather go to the front and harden the Riemann conjecture than sit here and listen to their nagging anymore.

After hesitating for a moment and taking a breath, Xu Chuan quickly typed and replied, "How much?" ”

"Not much. Ten million is enough, I'm not greedy, brother. ”

Sighing, Xu Chuan looked up at the matchmaker who was still praising with his mother how beautiful, virtuous, and excellent the matchmaker that girl was, and tapped his fingers on the screen a few times.

"Tell me."

"Hee-hee, okay!"

"Brother, you just say that you already have a girlfriend, you have a girlfriend, then the matchmaker will definitely not tell you about the object again, it's so stupid!"

Looking at the message sent on his phone, the corners of Xu Chuan's mouth twitched, this was probably the first person to say that he was stupid.

Well, such a simple solution, he really didn't expect it.

It's just that this pretends that he has a girlfriend, is it really okay?

The matchmaker got rid of these, what will her father say when the time comes?

If he says that he has a girlfriend, and the others don't say it, his mother will definitely ask for understanding.

Why don't you find a senior sister to pretend to be fooled first?

After thinking about it for a while, Xu Chuan felt that maybe it was indeed possible.

After all, if he had a girlfriend, no one would tell him about the blind date anymore.

It's not the New Year yet, and on the first day I came back, there were several waves of matchmakers.

If you really want to come every day, he is afraid that he won't have to do anything during the Chinese New Year, and he is busy with blind dates every day.

Moreover, if this thing is a legend, it will not be a joke.

He is a well-known scientist all over the world, reduced to the point of being forced to go home and go on a blind date

After thinking about it, Xu Chuan suddenly felt a thrill and shuddered.

If this spreads, his reputation in this life will be saved.

"Ahem."

Retracting the thoughts in his mind, Xu Chuan coughed lightly, interrupting the chat of several middle-aged women opposite, and also interrupting the cousin who was 'selling' his niece, and spoke.

"That, blind date, I already have someone I like, so I don't have to trouble my aunts."

Telling a lie, Xu Chuan said according to Xu Xiao's suggestion with a 'honest' face, but his girlfriend was replaced by the person he liked.

In this way, even if the parents ask, there is a good direction for explanation, anyway, it is just someone who likes it, and he is not afraid that his mother will force him to take it home to see.

Hearing this, the distant relatives who were chatting and 'selling', including Xu's mother, were stunned.

"You have a girlfriend? When did it happen? Who is it? Why don't you tell me? Is there still a mother like me in your eyes? ”

Stunned for a moment, Xu Ma, who was the first to react, looked at Xu Chuan suspiciously, and asked with a crackling face, with a look of disbelief, as for the person Xu Chuan said she liked, she was directly regarded as her girlfriend.

Xu Chuan coughed lightly and said with a smile: "Really, but I'm not a girlfriend yet, I'm chasing it, so I don't need to trouble my aunt to help me introduce my girlfriend." ”

After saying a word, he secretly added in his heart: It is true that he does not have a girlfriend, but it is not a lie to say that he likes someone.

By the stove, several middle-aged women were stunned for a moment, and then someone smiled and said, "Since Chuanzi already has someone he likes, what else do we want to introduce." ”

Some people persuaded with a smile, and some people said with a smile: "Isn't it that you don't have a girlfriend yet, Chuanzi doesn't have to be in such a hurry to reject everyone, take a look at it more, look at it more, maybe there will be someone who likes it more and is more suitable."

Before he finished speaking, someone else around him tugged at the man's sleeve.

It's okay to talk about this in private, it's not appropriate to say it in front of Xu Chuan.

was ripped off her sleeve, and the middle-aged woman also reacted, and hurriedly added: "Ahem, I mean, Chuanzi, you still have to catch up with the girl as soon as possible and bring her back." You're not too young, you're twenty-six or seventeen, and if you hang for another two years, you'll be thirty. People have no children after thirty, they are too old, and it is not so convenient to have children in the future."

As soon as these words came out, others echoed a few words.

"What Aunt An said still makes sense, Chuanzi, you are a little older, your parents are also older, and now they are married and have children, they can still help with it, and it will be inconvenient to be older."

"That's the reason, it's better to get married early. After getting married and stabilizing, your parents are relieved, and you can do your research with peace of mind, no? ”

In the living room, there was a lot of chatter, all of which were trying to persuade Xu Chuan to get married as soon as possible.

As for the matchmaking matter, no one will mention it.

Xu Chuan nodded, and after coping with it for a while, he found an excuse to leave and returned to the second floor.

On the sofa, Xu Ma looked at Xu Chuan's departing back suspiciously.

Although he had a stomach full of doubts, after Xu Chuan showed that he already had someone he liked, this time he didn't pull him to sit down and face these distant relatives who were talking about the media.

This stinky boy, can't he be a liar?

Things are weird, I'll go up and ask later!

After finally getting rid of his mother and the group of distant relatives who were talking about the matchmaker, Xu Chuan walked down the stairs to the second floor and breathed a long sigh of relief.

"How about it, brother, I'll just say that my method is easy to use, right?"

At this moment, a crisp voice with a smile in his ears came, Xu Xiao didn't know where it came from, looked at Xu Chuan with a tired face and asked with a smile.

Xu Chuan glanced at her, he cheated 10 million in one sentence, and he didn't rob the bank so quickly.

If he hadn't known that this girl was basically asking for money for experimental research, even if he had money, he wouldn't give it like this.

And for blind dates, the trouble is not those distant relatives who talk about matchmaking, but their own mothers.

If it weren't for his mother's stubborn pull and refusal to let him go, those who said that the media introduced the object, he would just find a reason to send it away. A distant relative who can't be beaten by eight poles is really important to him.

"Dude, remember my pay." Xu Xiao smiled and stretched out a finger in front of Xu Chuan's eyes.

"Ten million, that's fine."

Xu Chuan sneered and continued: "But if you ask me to help you make a mathematical model, you have to be paid, right?" ”

"I, a Nofi double award winner and an academician of the National Academy of Sciences and the Chinese Academy of Engineering, invited me to charge a fee, and it was not a simple matter. For the sake of your sister, I'll give you a 50% discount and charge you 20 million. ”

As soon as these words came out, Xu Xiao was stunned, looked at Xu Chuan with his mouth wide open, and said with a cry: "You didn't play like this, you promised to help me do it before." ”

Xu Chuan smiled and said lightly: "I did promise to help you make a mathematical model, but I didn't say that I didn't want to be paid!" ”

patted Xu Xiao on the shoulder, he left a word, turned around and entered his room.

"When will the remaining 10 million be transferred to me, and I will give you the mathematical model."

In the study, after Xu Chuan boiled a kettle of hot water, he took out his laptop from his backpack, clicked on the mailbox, opened the paper sent to him by Xu Xiao, and re-read it.

Although he doesn't know much about biology, he still knows a little bit about virtual reality technology.

In particular, he is familiar with computer technology linked to virtual reality technology.

If virtual reality is seen as a world, then the computer technology linked to it is the elementary particle that builds this world.

And mathematics is the law of the universe!

Flipping through the papers in his hand page by page, Xu Chuan's eyes were shining with interest, and he muttered to himself.

"It's kind of interesting, if you want to build a model that simulates nerves, you first have to transform the discontinuity of quantum theory into continuity, and then go around and back to discrete mathematics."

As we all know, if we start from the perspective of mathematics, mathematics itself can be divided into two parts: 'continuous mathematics' and 'discrete mathematics'.

Discrete and continuous, on the other hand, correspond to the two opposing and unified aspects of the movement of matter in the real world.

The earliest mathematics was essentially a discrete type of mathematics, but with the advent of calculus, it had a profound impact on the study of mathematics as a whole. Mathematics was studied from a continuous point of view, describing a variety of specific problems in the study of natural sciences, thus forming the continuous mathematics that is now dominant.

This also led to the gradual end of discrete mathematics.

However, with the development of modern science and technology, especially the rise of computer science and technology, discrete mathematics has regained its original position.

"Operability" is a fundamental issue in computing. It is determined that the structure of the computer itself and the objects it deals with are discrete, and even many continuous problems must be transformed into discrete problems before they can be processed by the computer.

So from this point of view, computer science and technology is essentially discrete mathematical technology.

While pondering, Xu Chuan wrote down lines of mathematical formulas on the manuscript paper.

Although he doesn't know much about biology and cranial nerve signals, he knows a little bit about the foundation of virtual reality technology.

With these, it is enough.

As for quantum theory and mathematics, I am afraid that no one knows more than him in this day and age.

Building a mathematical model for simulating neural signals and electrical signal conversion based on quantum theory is as difficult for him as it is for a college student to do a primary school problem.

As for modeling, although he is not a professional, don't forget that in controlled nuclear fusion technology, the mathematical model of high-temperature plasma turbulence is made by himself little by little.

Compared with the complexity of the high-temperature plasma turbulence model, the simulation of neural signals and the conversion of electrical signals are really too simple.

In front of the desk, Xu Chuan pinched the tip of the pen and danced quickly, like a top piano master, quickly grinding a string of smooth and neat characters from the paper.

"The evolution of isolated quantum systems follows the Schrödinger equation, and actual systems often inevitably interact with the environment, so in many cases they cannot be treated as isolated systems, which is a problem."

As lines of characters are written, the smooth handwriting occasionally comes to a halt.

However, for Xu Chuan, who was sitting at the desk, this level of problem obviously bothered him.

The thoughts in his mind flowed, the corners of his mouth hooked a curvature, and the ballpoint pen in his hand crossed a few horizontal lines on the manuscript paper, undoing the formula he had written down before, and writing down the lines of calculations again.

"If this is the case, for an open system that is weakly coupled to the environment, the evolution of its state can be approximated to be related only to the current state, and independent of the previous evolutionary process."

"With the Born-Markov approximation, the evolutionary equations satisfied by the open system can be derived."

In front of the desk, Xu Chuan kept sorting out the thoughts in his mind, and wrote the most basic mathematical principles on the manuscript paper little by little.

Building mathematical models for simulating neural signals and electrical signal conversion based on quantum theory is not very difficult for him, but the work is quite complex.

He plans to take advantage of the leisure time during the Chinese New Year to hand over the mathematical principles to others to build the model after all the mathematical principles are completed.

But then again, he was a Nofi double award winner to solve a Ph.D. problem in his dissertation.

emmmm, isn't this a bit too big and overused?

Forget it, whatever.

He's just this one sister, who doesn't spoil him?

And if virtual reality technology does make a major breakthrough because of this, it is completely worth it.

Anyway, it's just a bit of time for entertainment.

At least instead of wasting your time on introducing blind dates, it's better to sit upstairs and do some research.

Although the difficulty is average, he is still interested in the latter.
