Enter the Immortal Cultivation

PS: Sorry, I made a typo yesterday when I wrote Chebyshev! The translation of Chebyshev in that world is actually "Chexev"!

On the night of receiving the journal, Wang Qi and Chen Youjia both received a message from Chexev, the sender of the Wanfamen Northern School. The content of the letter was very simple, that is, this free and easy monk and legendary figure hoped to meet the two young geniuses who proposed the new law of large numbers and exchange ideas.

Regardless of what Chen Youjia thought, Wang Qi was very excited about it.

The Northern School corresponds to the Petersburg School in the history of the earth, represented by Chebyshev, Markov, Lyapunov, etc. Although in terms of reputation and presence in the history of mathematics, it is not as good as the Paris School, Göttingen School, Polish School and other European mathematical schools, but its influence on later generations is not inferior to any university school.

Chexev is the founder of the Wanfamen Northern School, one of the few great masters of the Wanfamen, and a rare strong man in the fields of number theory, function, integral, etc.

After the two people replied, they spent about a day preparing. On the morning of the third day, they entered the Wanxian Fantasy together and followed the signpost sent along with the letter to a place in the fantasy.

The scenery of the northern country, thousands of miles of ice and snow. In this silver fantasy, a semi-open hut was steaming with heat. Two old men were sitting in front of a table, talking about something. Rich people always like to set the fantasy of the chat room to what he is most familiar with, and this northern king is no exception.

The old man sitting on the main seat had white hair and beard. But he didn't look old, he was full of energy and strong, and his white hair and three-foot-long beard were meticulously groomed.

Well, it formed a sharp contrast with the other old man next to him.

Wang Qi couldn't help but be surprised: "Teacher Feng? Why are you here too?"

Feng Luoyi's image was not so bad. But it was a little worse than Che Xuefu's meticulous look. I don't know who is the monk from the martial northern country.

Feng Luoyi smiled and said, "Everything in the Fantasy World of Ten Thousand Immortals is handled by me, so it's normal for me to be here. Besides, the new things you have come up with are very interesting, and I also want to participate in it - are you not welcome?"

Chen Youjia pulled Wang Qi and lowered his head and said, "How could it be?"

For Chen Youjia, who is interested in applied mathematics, Feng Luoyi, the strongest applied mathematician, is simply an idol-like figure.

Chebyshev is much kinder than expected. After hearing Wang Qi blurt out "Teacher Feng" once, he glanced at Feng Luoyi. Then he smiled at the two juniors and said, "You don't have to pay attention to this guy. Don't worry about me. I just want to talk to you two young people. Talk about your ideas about probability theory."

Probability theory...

Wang Qi looked at the old man with a complicated look in his eyes. The mathematical law called "Chen Wang's Law of Large Numbers" that he and Chen Youjia came up with is called Chebyshev's Law of Large Numbers on Earth. Facing this isotope, he always feels a little weird.

What surprised him even more was that it was Chebyshev's latest paper, "A Generalization of Chen Wang's Law of Large Numbers".

That was clearly Markov's law of large numbers.

According to the history of mathematics on Earth, this was the representative achievement of Markov, Chebyshev's disciple. It is the cornerstone of modern probability theory.

Although it has long been known that Shenzhou Xiaoyao's research ability and actual level are higher than their counterparts on Earth, it was the first time that Wang Qi was shocked in such a direct way.

——Well, it was so naive to think that I could finish the law of large numbers quietly by myself...

Shenzhou underestimated the role of probability too much, thinking that it was just an approximation of "absolute causality". As long as all the conditions are known, all uncertainties can be eliminated and the inevitable result can be obtained - this is the creed of Shenzhou. Because the calculation power of the Yuanshen is too powerful compared to the human brain, many monks simply use primitive statistical tools, and there are not many famous mathematicians who go back to the field of probability. Chebyshev had no idea of ​​​​doing probability before.

As for Markov... He is also a "missing" person. There is no him in the history of Shenzhou. Most of his achievements in the history of mathematics were also developed by the Northern monks represented by Chebyshev.

In addition to Markov's law of large numbers, which is an extension of Chebyshev's law of large numbers.

However, Wang Qi underestimated the freedom of this world after all. Because of their deep accumulation, just a little bit of things can inspire their inspiration.

This may not be good news for Wang Qi. He should not think about monopolizing the entire research chain in the future. He did not memorize many papers before crossing over. What he can remember now must be the achievements that he had learned about in his previous life and had an important position in academic history. I don't know how many great powers are watching such achievements. As long as there is a breakthrough, they will rush in.

But now it seems that this is also an opportunity...

Chexhoff smiled and said, "I have seen your results. It is a great research. How did you two think of starting from this aspect?"

Chen Youjia opened his mouth to say, "This is an idea I had a long time ago..."

Wang Qi's voice interrupted him neatly, cutting off Chen Youjia's words like a sharp blade: "Because this is inevitable in the accident. The law of large numbers is the skeleton of the probability field and the most practical problem in this field."

Chexhoff raised his eyebrows: "Oh? 'Most'? You are so sure? Why?"

Wang Qi was relaxed and talked freely: "First, we need to think about a question, what is the meaning of our mathematics?"

What is the meaning of mathematics?

Mathematics is a highly abstract, highly idealized and fragile existence, which is not the same as the material world. There are no events that occur perfectly according to probability, no truly uniform texture, and even no standard straight lines and standard circles.

What we can draw in the material world is only "approximation". Approximate straight lines and approximate circles.

Strictly speaking, the premise of all mathematical theorems cannot be perfectly satisfied in the real world, so the conclusions asserted by mathematical theorems cannot be perfectly established in the real world.

This conclusion can also be extended to all theories. The laws mastered by humans are just the statistical averages of random events, nothing more.

So, what is the meaning of science and mathematics?

Feng Luoyi nodded affirmatively: "I understand what you mean. The law of large numbers is all, and approximation is meaningful. My way is not the way but close to the way. The theory of the Immortal Alliance and the way today are probably related in this way, right?"

The inevitable is contained in the accident.

Chen Youjia looked at Wang Qi blankly. Since she always had no expression, no one could tell what she was thinking.

"This bastard...I was the first to do this! You were the last to get involved! Why do you talk more beautifully than me?"

Cheschoff was very fond of this young man: "You really have a lot of ideas. It seems that we need to communicate more." (To be continued ~^~)
