Chapter 96 Come to Yanbei after you celebrate the New Year
The opening ceremony was very lively.
Different from the school’s orientation meeting, after the big shots gave their speeches, there was an hour-long theatrical performance.
Unlike those dull meetings, the opening ceremony did not take long for the big shots to make speeches or speeches.
First the principal of the host school spoke, then a big boss from the School of Mathematics of Yujiang University came to speak, Academician Tian came third, and finally a provincial leader from Yujiang Province announced after his speech Winter camp officially opens.
Four people spoke, plus the national anthem was played before the formal meeting, and it took less than half an hour in total.
The next step is a one-hour cultural performance.
The opening ceremony officially started at nine o'clock and ended on time at 10:30, and then spent another half an hour taking photos on the school track and field. Then the staff, with the cooperation of the team leaders, led the contestants to start Visited the campus and got familiar with the examination room for tomorrow’s competition.
After the process was completed, the team leaders of each competition area counted the number of people for the last time and then returned to the hotel. After dinner, the entire afternoon and evening were the time for the campers to communicate freely.
It is said to be free communication, but in fact it is free movement.
As long as they don't miss the time when the team leaders of each competition area count the number of people at 10 o'clock every night, the organizers don't care what the campers do.
However, the personalities of the competition area leaders are different, and the requirements for the contestants are also different.
A cautious team leader will ask all contestants to stay only in the hotel. In order to fear that something unexpected will happen if everyone is too free, they may simply arrange two papers for each person in the afternoon, or let everyone stay in the hotel. Make friends there.
A more relaxed team leader is allowed, as long as the players take a leave and go out together to have a look at the local customs of Ningshui. Of course, they must ensure that they return to the hotel before the head count every night.
Leader Luo from Xingnan belongs to the latter, but the requirements are slightly stricter. For example, during the winter camp, you can only eat in hotels specified by the organizer. You are not allowed to eat out, let alone order takeout. The main reason is that I am afraid that I will eat too much during the exam, which will affect my performance.
Of course, Qiao Yu couldn't ask for leave today.
After lunch, Qiao Yu took a nap in the room for half an hour. After getting up, he started looking for more basic mathematics videos on the Internet as usual.
For example, Qiao Yu’s favorite video recently is analyzing the Riemann zeta function from various angles.
For Qiao Yu, the ζ function is indeed a very interesting research point. It is closely related to the distribution of prime numbers, and at the same time it can give a glimpse of the beauty of infinite series. The ζ function can be expanded through analytical continuation. to almost the entire complex plane.
Of course, the most important thing is that Qiao Yu feels that the ζ function is helpful in solving the problem of factoring large prime numbers, although the connection between the two is not obvious now.
For example, by completely analyzing the zeta function, it is possible to find the specific ways in which prime numbers control the behavior of certain complex functions.
As we all know, the zero-point distribution of the Riemann zeta function is closely related to the distribution of prime numbers among natural numbers.
If the zero point distribution of the ζ function has a hidden structure that can be directly linked to the relationship between the zero points with a real part of 1/2 on the complex number plane and the factorization properties of specific integers, maybe we can Makes factoring large prime numbers simple and efficient.
For example, directly use the zero point of the ζ function to construct a formula for mapping composite numbers and their prime factors, and form an algorithm, and then bring large integers into this formula to quickly find Its prime factor.
In this way, the most mainstream RSA encryption algorithm will be self-defeating. After all, the principle of RSA is actually the product of two prime numbers as the public key, and these two prime numbers are the private key.
If this method can quickly find the private key through the public key, the mainstream encryption principle of the entire Internet will be self-defeating.
Look, a series of principles of number theory are actually so simple that even elementary school students can understand them. But if you really do it, you will know how difficult it is.
At least a seemingly simple Riemann hypothesis just needs to prove that all non-trivial zero points of the ζ function are located on the straight line with a real part of 1/2 on the complex plane.
The result is that a full 165 years have passed since Riemann proposed this, which is equivalent to more than 60,000 days and nights, but no one has been able to solve it. This is when all mathematicians know that once they can solve this problem, they will directly become famous and get various medals and bonuses.
But then again, this is actually the fun of mathematics. If every problem is easily solved, there will be no fun at all.
For Qiao Yu, this kind of mathematical problem is nothing more than a game of finding patterns. By connecting numbers that are related to each other through a pattern that no one else has discovered yet, he can make a lot of money.
It’s just that this law is hidden very deep and it’s not that easy to find.
Just when Qiao Yu viewed the third video, there was a knock on the door. Lan Jie, who had been sitting on the bed looking at his phone, stood up, but instead of opening the door, he rushed to Qiao Yu. He winked.
“Here we come.” Qiao Yu quickly stood up and opened the door.
Sure enough, Academician Tian Yanzhen, whom I had just met on the rostrum during the opening ceremony in the morning, was standing at the door, and Team Leader Luo was accompanying Academician Tian.
In fact, he was still a little surprised, mainly because he didn't expect Academician Tian to come to him on his own initiative. He originally thought that it might be Team Leader Luo who notified Lan Jie this afternoon and took him to visit Academician Tian.
If you go to him, you will probably have a chat alone, but if you take the initiative to come here to find him, it probably means that today is a very ordinary conversation. After all, you can’t drive away both Leader Luo and Lan Jie. Let's go?
"Academician Tian and Team Leader Luo, okay, Academician Tian and Team Leader Luo, please come in." Qiao Yu said politely.
Yesterday, Lao Xue specifically explained that he is still a child and he just needs to be himself honestly.
Qiao Yu's understanding of his true self is probably that of a good boy who is polite and knows how to advance and retreat in front of his elders.
"Okay, I'm here unexpectedly. I won't disturb your rest, right?" Tian Yanzhen asked casually when he walked into the room.
"No, I usually take a nap for half an hour and get up early."
"Academician Tian, hello, I am Qiao Yu's Mathematical Olympiad tutor at school. My name is Lan Jie Please take a seat."
Ran Jie, who was standing in the room, saw Tian Yanzhen and said hello quickly.
"Hello, okay, stop standing, everyone, sit down, sit down."
There were only two stools in the room in front of the table by the window. Tian Yanzhen and Leader Luo sat on the stools, while Qiao Yu and Lan Jie sat directly on the edge of the bed by the window.
After a brief greeting, Tian Yanzhen took the initiative to ask: "Have you guessed the reason why I came to see you today?"
"Leader Luo came to ask you yesterday I didn't guess it at the time, but I guessed it after calling Professor Xue," Qiao Yu said honestly.
"Xiao Xue is a good person. If you are valued by him, it means you are good. Today I am just here to have a casual chat with you. You don't have to have any psychological burden, let alone worry about saying the wrong thing." Tian Yanzhen said with a smile.
Qiao Yu replied easily: "Well, Professor Xue told me the same thing yesterday. He said that if I am really lucky enough to meet you, I just need to stop being clever and be myself honestly. Okay. So I don’t think there’s anything to be nervous about.”
"Haha, this little Xue... But you really don't need to be clever. After all, we are mathematicians, and cleverness is of no use. We still have to rely on great wisdom." Tian Yanzhen said with a smile.
Actually, when Qiao Yu said those words, he noticed that Team Leader Luo next to Lao Tian frowned a bit, but when he saw that Lao Tian didn't pay attention to this, his eyebrows gradually relaxed.
Of course, Qiao Yu didn't care much about these micro-expressions.
Although the big boss in front of him is indeed a good choice for him, it is not the only choice.
Lao Xue also said yesterday that Academician Tian is only one of the current flagpoles of the Chinese mathematics community, indicating that there is another flagpole. Since his paper can be appreciated by this person, I believe that he will not completely ignore it after it is published.
If he really couldn't rely on either party, Qiao Yu felt that it was not impossible to go to Yujiang University and seek refuge with Lao Xue.
Although Lao Xue said that he was not good and could not handle anything, Lao Xue’s mentor was awesome! He was a serious Fields Medal winner. It was also a way to find a way to connect with his mentor's mentor through Lao Xue's relationship, so Qiao Yu was really relaxed and didn't feel nervous at all.
“I read the paper you are going to submit to Journal of Number Theory. It is very well written. But I am more curious about the story Xiao Xue told me. You saw his equation on the forum Have you ever systematically studied algebraic number theory?”
After laughing, Tian Yanzhen asked seriously.
“You can’t say that you haven’t studied systematically at all, right?” Qiao Yu thought for a while and replied: “I have read a lot of articles and videos in bits and pieces before, and it happened that Teacher Lan gave them to me during that time. I have almost finished reading his treasured copy of "Algebra and Number Theory."
"Oh? Which version of "Algebra and Number Theory"?" Tian Yanzhen asked.
"Written by Mr. Feng Keqin." Qiao Yu replied immediately.
This name is very impressive. In fact, Qiao Yu is now very impressed by all the names of people with the surname Feng. Even von Strofsky is imprinted in his mind...
< br>Tian Yanzhen nodded, glanced at Lan Jie who was sitting next to Qiao Yu and looked embarrassed, smiled, and asked: "In other words, you have watched some scattered videos on the Internet. Just follow a number theory textbook and solve that equation on your own? "Huh...it's not that easy. You don't know, I was so angry at that time. I worked on that equation a little bit in the past three days." There is no way, there is no way to solve it. I really doubt that the equation has an integer solution. I even complained on the forum at that time
As a result, I didn’t know it was Professor Xue at that time. He replied on the forum that in the future mathematical life, there will definitely be an integer solution. There were also a group of people there who were sarcastic and sarcastic. I felt very angry at that time!
However, everyone said that there is a solution. I analyzed it more carefully at that time, and found relevant articles to study it carefully. Later, the equation was a smooth projective curve with genus 1 on the domain, and then I suddenly found it. inspired.
The equation was directly simplified into a closed elliptic curve problem, and then a breakthrough was found. The next step was to repeat the calculation process to find the point where the three values are all positive integers.
Really, I spent ten days trying to understand this equation. In addition to studying at a set pace in the morning, I spent the afternoon and evening solving problems. Sometimes I stay up until two or three in the morning! "
Qiao Yu said vividly.
He was indeed deeply impressed by that time. After all, it was probably the first time that he went all out to solve a mathematical problem.
After finishing speaking, Qiao Yu said: "By the way, I also made a lot of thoughts and summaries on this question every day, and they happened to be copied to the computer given to me by the school. You can Do you want to see it?”
“Oh? I really want to see it,” Tian Yanzhen said with interest.
The computer was already on. Qiao Yu stood up, came to the table, and clicked the mouse. A paused video about the ζ function appeared. However, Qiao Yu quickly minimized it and clicked on it. D drive...
At this time, Leader Luo, who had been by his side and had not spoken a word, was already a little confused.
He knew that Qiao Yu had won the gold medal with a perfect score in the number theory group at the Little Libaba International Mathematics Competition, and he also knew that Qiao Yu had received the only perfect score in Xingnan in the provincial league this time.
But this kid solved an equation in the number theory forum, and even wrote a paper to be submitted to an internationally renowned mathematics journal. He really didn't know these things. I haven't heard anyone from Tieyizhong mention it.
Thinking of this, I couldn't help but turn my head and look at Lan Jie melancholy.
Lan Jie keenly felt Leader Luo's gaze, and then smiled politely.
Although he knew that Qiao Yu solved the equation that Xue Song posted on the mathematics forum, he did not know some of the details. Today is the first time I heard about it.
As for not keeping up with the head about some things...
It seems that we can't blame him, after all, no one has asked him. Moreover, the paper has not been published, so what I say everywhere seems like showing off. Lang Jie happens to not be the kind of person who likes to show off everywhere. Anyway, he doesn't have much pursuit, just being a high school math teacher for the rest of his life is fine.
In fact, there are two types of people in schools and similar institutions who are really working hard to support the business of the unit. One type is those who feel that they still have hope and work hard and are responsible to the leaders; the other type is that although I am very satisfied with the current situation. Although I have no motivation to climb up, I still work hard for the sake of conscience...
Obviously Lang Jie belongs to the latter, so people of his temperament naturally don't care what the leader thinks. He, let alone a team leader, cannot be considered his leader.
So Xiaoxiao passed away.
However, Tian Yanzhen was in front of the computer and carefully browsed Qiao Yu's daily summary documents.
Qiao Yu did really well in this area. Not only did he keep records when he solved the equation problem, but he also had various backups and records, as well as his thoughts when writing papers and watching videos.
He even helped his fellow students revise their papers and read more documents to record his thoughts.
Especially when some seniors cite documents incorrectly, they will even analyze the reasons for such mental retardation in their daily reflection reports.
Of course, Qiao Yu recorded this not to teach his fellow seniors who only gave him a tuition fee, but to keep it as a backup in case he really becomes a professor in the future and can lead students to do projects. Okay, we can't let our students be so embarrassed.
In addition to these, there are also Qiao Yu's various insights after appreciating the beauty of mathematics, and there is even a complaint about an Olympiad question that destroys the beauty of mathematics...
Of course, this part of the content Qiao Yu did not intend to give to Tian Academicians read it.
Sharing his journey of solving equations, or his insights on mathematics, is because this is the most proud thing for Qiao Yu after he started studying mathematics seriously. Let him be his true self, and naturally he will have to give it a try.
Especially in front of an academician.
But when he saw Academician Tian reading the articles with great interest, Qiao Yu was a little confused again...
After all, this thing was written for him to read, and it contained a lot of messy stuff. For example, he often complained about some unreliable senior brothers.
"Well, Professor Tian, this is the last article about the idea of solving equations."
"Oh, these shouldn't be the kind of very private diaries, right?"
"That's not true, but..."
"That's it, then I'll look through it casually."
Qiao Yu regretted a little. Lao Tian's mouse had already moved to the upper right corner, and he was about to click the close button...
"Huh? Xiao Xue also asked you to help review the papers of his students?"
"Uh..."
Before Qiao Yu thought about how to answer, the boss suddenly said: "Are your personal trainers in Star City so cheap? You are obviously too cheap, right?"
This is...a confidant!
The boss didn't even say cheap, but used the word "cheap"...
"If you think so, you are already in the postgraduate stage. When you write your thesis assignment, you haven't mastered some of the most basic things. , indicating that the family is definitely not short of money.
At least the students I have seen who come from poor families still insist on taking postgraduate entrance examinations. When it comes time to complete an independent thesis, the most basic things are required. They have already mastered it very solidly.
Especially for these graduate students who are still confused about mathematical logic when doing theorem proofs. Most of them come from very good families and even have many future jobs arranged.
< br>It just requires a diploma from a famous university. Your higher fees will not have any impact on their lives, right?”
After saying that, Tian Yanzhen turned around and jokingly asked Leader Luo next to him.
"Haha, yes! We also have students like this at Xingnan Normal University." Leader Luo suppressed his surprise and echoed with a smile.
Hey guys, Qiao Yu can actually tutor graduate students on their thesis?
Isn’t this too outrageous?
No wonder he is in the eyes of the boss.
"One more thing I would like to commend you for is that when you are helping your fellow seniors to review their papers, you will take the initiative to do extended reading and increase your knowledge. I have taught so many students, and there are not many who will take the initiative to do this. This is a habit. Very good, be sure to stick to it, it will be helpful to you in the future."
"Okay," Qiao Yu replied honestly.
After hearing this answer, Tian Yanzhen smiled, and finally moved the mouse to close the document where Qiao Yu recorded his daily study insights and various complaints.
Fortunately, I haven’t finished reading it. There are still a lot of his various complaints that I haven’t read yet.
After closing the files on the computer, Tian Yanzhen turned around, looked at Qiao Yu and said kindly: "In this way, after the new year and the start of school, I will first come to Yanbei University to adapt to university life. After arriving at the national team How about you just go to the training camp as usual, your grades don’t matter, and you can go directly to the elite class at Yanbei Institute of Mathematics when the summer semester starts.”
Qiao Yu was stunned, mainly because he didn't expect Lao Tian to be so direct. He thought he was just here for a casual chat today.
Then I thought of Lao Xue's repeated instructions that day, and asked: "Is that... a bachelor's, master's and doctoral program? If so, who will be my future mentor?"
After hearing what Qiao Yu said, Leader Luo opened his mouth, but in the end no words came out.
PS1: Dear book friends, the 13th day of the 10,000-word update is complete!
PS2: Qiao Yu is going to university soon. He still lacks travel expenses to the capital. He urgently needs your monthly ticket support!
PS3: Recommend a new book to everyone: A friend of mine who is good at writing folklore has turned to a new fantasy work: "Starting from the Kingdom of God in the Palm"
