Chapter 75 A phone call that changes perception (Part 1)

Qiao Yu admitted his cowardice very simply.

Face? Doesn’t exist!

He is a fifteen-year-old kid who has not yet reached the age where he needs to save face.

If a group of professors really want to talk about face with him, then it will appear that those professors have no face.

Come on, if you can, come and quarrel with me, a fifteen-year-old kid, and let the news spread to see who will be embarrassed! This is an unstoppable and shameless age advantage. If it spreads, it will directly kill the professorship. But obviously,

Qiao Yu again overestimated the composition of this forum's population.

It would be fine if you just chatted privately with professors, but posting such a post directly on the forum really made many graduate students break their guard. "Is this account hacked? Please show me your method of solving equations first."

chat!"

"I feel offended!"

"Haha? Middle school students, do you think we will believe it?"

"No? Qiao Yu? Could it be the one from Star City Railway No. 1 Middle School?" "What Star City Railway No. 1 Middle School?"

"The list of little Libaba's finalists is out. The only gold medal winner in the algebra and number theory group is Qiao Yu. The school is Star City Railway No. 1 Middle School. You can find out by going to the official website." "What? It means that this rookie is really

Middle school student?"

"Hehe, hehe, hehehe. Newbie?"

"Let me go, brothers, it turns out to be real! Sorry to bother you, I'll leave first!" "Wait for me and delete your account together, I won't play anymore!"

"This classmate Qiao Yu, I advise you to be more sensible and give you two minutes. It is best to delete this post before my tutor sees it!" "Everyone, I combined Little Libaba's algebra and number theory.

Here’s a screenshot of the rankings, please evaluate it yourself.”

Yes, for these graduate students, is Qiao Yu here to apologize? This is just to show off the university! Applying for the question-answering system has ensured that the people who can hang out in this forum are all mathematicians.

So no one’s heart is purer than anyone else’s. Today is Saturday, and the day after tomorrow is Monday.

Although it is summer vacation, those who have studied graduate school know that in order to maintain the consistency of research progress and academic results, in most cases, these graduate students, who are no longer valuable, also need to continue to work and study during the winter and summer vacations.

Even if pure mathematics research is not as hard as engineering, and you don’t need to work around the laboratory twenty hours a day, and even your enlightened tutor will allow you to go home for the summer, but if you want to graduate on time, weekly reports are generally indispensable.

Even if it is remote reporting through WeChat or other software.

When the supervisor is unavailable, there will usually be a junior supervisor watching over him. Those graduate students who have not completed the tasks at hand can already imagine the supervisor's face after the news spreads, and what he is likely to say. "That's it? You've been waiting for so long

Are you handing over such a useless thing? You are really going back more and more, you are not even as good as a junior high school student, do you know that?"

What’s even more sad are the domestic students in the forum who participated in the Little Libaba Mathematics Competition, entered the finals, and even won prizes.

Although there are five tracks in the finals of the Little Libaba Mathematics Competition, this forum is for discussing algebra and number theory. The graduate students hanging out here must have chosen the track the same way as Qiao Yu. At this time, someone took a screenshot of the final results to the forum Inside, it just doesn’t look good.

"Tsk, tsk, tsk...this ranking...forget it, I won't comment, let's go to the next one." "I don't understand either, let's go to the next one."

"Brother Zheng from Huaqing, first of all, I would like to congratulate you on winning the bronze medal. But it's really not me who started the problem. That Qiao Yu came to the forum to post such a post at this time. I think he just wanted to slap you in the face." Ahem, I also think this is a little too much. The administrator should come out and delete this post, it attracts too much hatred."

"I told you, don't do this. That high school student might be snooping on the screen and enjoying himself." Qiao Yu had indeed been snooping on the screen, and he kept refreshing the snooping screen.

This forum is too simple. There is no real-time reminder function for replying. It is not even as good as the post bar. You can only see new comments by constantly refreshing them manually. It is just a matter of adding a few lines of code between the front end and the back end. 80% of it is The administrator is too lazy to add such useful features.

But I have to say that the emotional value obtained in the forum is much more enjoyable than in the group chat of Class 13.

The only pity is that the forums where people keep complaining are not very high-level, not to mention mathematics experts, there are only a few weirdos. Most of them are mathematics masters and mathematics experts, with a few mathematics upstarts interspersed among them. .But this is also good, you can play more relaxedly.

For example, when he saw a math guru saying that he was peeking at the screen, Qiao Yu replied without hesitation.

"Uncle, please don't slander me. I didn't peek at the screen at all! And I only entered the first year of high school in September, so the most you can say is that I am a quasi-high school student. After all, I am here to apologize to all uncles and aunts. , we can’t throw away a large group of high school students!”

With such a low-level title, he is definitely not a professor.

Since everyone is a student, Qiao Yu is absolutely honest and must show an attitude of apology.

Looking back now, when a bunch of math geeks ridiculed him, these little Karami were also watching and supporting him, so we must not stop apologizing to them just because we are all students. As promised, all living beings are equal. Xiaozhou, China .

It's already the end of August and school is about to start...

So Professor Xue Song from Yujiang University is busy on blind dates today.

Anyone who has been a professor in a university knows that as long as they have obtained the official establishment and have become a leader in the research field, their life during the semester is almost the same as during the winter and summer vacations, and there is no concept of whether the school should be open or not. Some professors attach great importance to teaching, and will go over the courseware again before the semester, and even modify and update it to a certain extent.

Other professors are probably more casual. They forget that the semester is about to start unless their graduate students remind them. They are confident that their knowledge is profound enough in class, and they can adapt to changes in every class, making those silly undergraduates worship them, and they don’t need to do anything at all. Special preparation.

Of course, for some young professors, well, there is actually not much difference between winter and summer vacations and the beginning of school.

Under the pressure of being promoted or leaving, both scientific research and teaching cannot be delayed. During the winter and summer vacations, I also work hard overtime, either busy with projects or busy publishing articles. Xue Song is actually somewhere in between.

In fact, he cannot be regarded as a powerful academic leader in the mathematics major of Yujiang University, but he is definitely a leader among professors of his age. Moreover, Xue Song has a strong say in the relevant directions of his research.

Not only because he has published two important papers, but also because some related research groups often invite him to participate in seminars when doing research projects. He can indeed put forward some very good suggestions. These suggestions must not be written into papers. , but colleagues in related research fields all know that Professor Xue Song of Yujiang University has a solid theoretical foundation, active ideas, and strong comprehensive strength.

This is also one of the manifestations of status in the academic circle. Contributing unique ideas to high-level academic discussions is also one of the sources of fame. But this kind of fame is difficult to break out of the circle.

Xue Song is only thirty-five years old this year. It is the age when he is in the prime of life and can produce results. His energy is mainly focused on his career, and some personal matters are naturally delayed. In addition, there are very few women in the mathematics circle, whether it is It’s the same whether at home or abroad.

So Xue Song, like Lan Jie, is still single in his thirties.

The difference is that Lang Jie's parents are open-minded enough and don't think being single for a lifetime is a big deal.

However, Professor Xue's parents were more traditional and held the idea of ​​being unfilial and having no offspring, so they were anxious and angry every day about their child being single. Naturally, they mobilized everyone around them to help Xue Song find his future partner. But they couldn't resist it. , I can’t resist it at all.

Yesterday, his aunt just introduced a new female colleague from a public institution. Today happened to be Saturday, so they made an appointment to have a meal. Originally, Xue Song was just doing some errands, and after dinner, he planned to say goodbye and leave.

As soon as he walked out of the mall, the girl thanked Xue Song for inviting him to dinner. There happened to be a summer movie called "Chicken Doll" that I had always wanted to see, but because my work unit had been very busy, I couldn't go. Plus, there was still time today It's early, so I want to invite Professor Xue to watch a movie together.

The girl took the initiative to invite, and Xue Song couldn't refuse, so she could only happily agree. By the time the two of them arrived at the nearest cinema, there were only 7:40 tickets available.

The girl bought the tickets, Xue Song bought two drinks and two buckets of popcorn, and started watching the movie when the time came.

The first half of the movie was enjoyable, but in the second half, Xue Song’s cell phone started to get restless again, vibrating in his pocket. It was naturally inappropriate to take out the cell phone in the cinema, Xue Song I excused myself to go to the toilet and walked out of the screening room before taking out my phone and taking a look. Good guy, in just a while, I got three missed calls, and none of them were from the same person.

What kind of emergency is this?

Xue Song responded directly in the order in which he called.

"Professor Chen, is something wrong?"

"Old Xue, I remember that you were on the marking team for this Little Libaba competition, right? Send me a screenshot of Qiao Yu's answer." "Huh? Professor Chen, you may have misunderstood. Qiao Yu has just graduated from junior high school.

, not here yet."

"Hey, I know. Oh, you haven't been to the forum yet, right? Just go to the forum and you will know. That guy is the rookie who solved your equation before." "What? Qiao Yu is the rookie?" Xue

Song was stunned for a moment.

But now that I think about it, it really fits that rookie status.

The forum IP shows that the address of the rookie when posting is Xingnan Province. Qiao Yu is indeed from Xingcheng, Xingnan Province, and goes to school in Xingtie No. 1 Middle School. There is also a metaphor in the ID. The most important thing is, Little Li Baba's competition

He was obviously able to do it with ease. But why didn’t he think of it at the time?

"Old Xue, Old Xue... I've been talking to you for a long time, why don't you talk anymore?" the other person urged.

"Oh, I was thinking about other things just now. Huh...it turned out to be him. No wonder I couldn't find out! But he is still a junior high school student..." Xue Song subconsciously sighed. It was not just a sigh, there was actually something in his emotion.

With some horror.

I didn’t expect that I was simply deceived by Qiao Yu’s age. He’s 15 years old!

Even though he can skillfully solve the math problems given by professors, solving the equations he gave is more than just solving problems. It also involves some of the latest research directions. Such as modular form, number theory geometry, and

Local field theories such as p-adic theory.

The questions in the Little Libaba Mathematics Competition are also difficult, but in a different direction. The form of the competition questions is very direct. Even if they are also looking for integer solutions, they are usually limited to a specific range, and the basic problem-solving skills of the contestants are tested, as well as

Flexible use of theorems and methods.

Solving his equations directly involves the theoretical depth of modern number theory, and its solution requires more complex algebraic geometry tools, arithmetic geometry tools, and advanced skills in numerical analysis. The simplest and easiest to understand difference is that the competition questions

The questioner knows the correct answer and can give detailed steps to solve the problem as a reference answer.

But for the equation he gave on the forum, he, the question maker, didn't even know the correct answer. He only confirmed that there was an integer solution, and he didn't know what the numerical solution was.

In other words, although Qiao Yu is only fifteen years old, and although he has not had time to go to high school, let alone go to college, he already has the ability to do mathematical research, and this ability has even been indirectly verified. Even

It can be said that Qiao Yu is not only capable of answering competition questions, but his research ability is stronger than many mathematics graduate students in China.

What's the difference?

Let's put it this way, on the day Qiao Yu disclosed the solution to the equation, he assigned finding the numerical solution to the equation as an additional task to his graduate students. There were master's students, doctoral students, and both master's and doctoral students, but more than one

Months have passed, and still no one of his students can find an idea.

It only took more than ten days from the time he gave the equation on the forum to the time Qiao Yu gave the correct numerical solution.

Comparing one person to another really makes me angry! At this moment, Xue Song didn’t know whether to say that his students were too stupid, or that Qiao Yu’s ability was too strong.

"Yes, it's because he is still a junior high school student, so we can't let him go. This kind of thing depends on your own methods. If you can grab this kind of student, the tutor will not have to think about it during the master's and doctoral studies.

He can be used as a small guide. So can you send me a screenshot of his answer to the question? I can take a look at his thinking."

After hearing this, Xue Song took a deep breath and said: "I'm outside right now, so it's inconvenient. But you don't need to look at it. He is the only one with a perfect score in this year's number theory track. The problem-solving process is not much different from the standard answer.

Even more detailed. Also, don’t try to get his idea. He can’t win over Huaqing or Yanbei. I have communicated with him. This guy has a very clear plan for the future. Even our Yu adults don’t like it, let alone your school.

Already."

"No, have you already communicated with him?"

"Yes, I even treated him to a meal. During the finals, he was one of the contestants invited to Xiaohu to participate in the competition. I happened to take a look here." "What about his tutor? Can he tutor someone like this?

The level of students is very high, right?”

"The teacher who brought him here is called Lan Jie. He has a bachelor's and master's degree from Shuangdan University. I checked his master's thesis on CNKI, "Combinatorial Design and Experimental Optimization: Research Based on Response Surface Method." You can know the level by checking it out.

How’s it going? Anyway, my evaluation is the most basic double-dan master’s degree.”

"No, then how did he get his accumulation in algebra and number theory? Not to mention self-study."

"Otherwise? Don't ask me everything. You can find your own way to find out the enrollment rate and Qingbei rate of Xingcheng Railway No. 1 Middle School in recent years? Okay, that's all I know, so I'll give up now."

After saying that, Xue Song hung up the phone directly.

He didn't even bother to say too much to his peers who were obviously trying to take advantage of the other party's ignorance.

He has been teaching at Yujiang University for five full years, so he naturally knows a lot about all kinds of nonsense in the academic world. Even if he doesn't deliberately inquire about it, many things will automatically trickle into his ears.

Various inheritances, factions, and even because there is some overt and covert competition between a certain director and a certain director on a certain project, any simple cooperation between a graduated and uninformed student and the other party will be regarded as treason by the same disciples...

Many intellectuals who have already stood at the top of the pyramid have narrow minds than the tip of a needle, but Xue Song has always been unwilling to get involved in such nonsense.

As for the competition for results, there are more things. On the surface, they are all harmonious, but secretly they probably want the other party to die. Xue Song has already offended a lot of people for this, so naturally he doesn't care about offending more people.

After roughly knowing what the situation was, Xue Song did not call everyone back, but directly logged into the forum with his mobile phone. As expected, he saw Qiao Yu's post again, um, and a private message.

Xue Song first glanced at the private message, ignored Qiao Yu's little thoughts, and clicked on Qiao Yu's post. After seeing a group of students complaining there, he exited the browser and opened WeChat.

It was almost as he imagined. The group of professors who had been chatting animatedly to guess who the rookie was was completely deserted.

He couldn't help but sneered twice, then he called up his address book and was about to call Qiao Yu. He hesitated again, then walked into the screening room, found the girl who was on a blind date today, and said, "Sorry, the school just called. , it’s a little urgent, I have to leave today. Shall we contact you later?”

"Oh, okay, Professor Xue, work is more important." "Thank you for your understanding."

Xue Song smiled apologetically, turned around and walked out of the screening room before dialing Qiao Yu's phone number.

There was no way, Xue Song felt that this phone call would take a long time. He couldn't let his girl wait in the screening room. He didn't have to like it, but he couldn't disrespect it.

Qiao Yu, who was enjoying himself on the forum, immediately picked up the call when he saw an incoming call on his cell phone.

How to argue, Qiao Yu has already made plans in his mind. After all, some things will have to be faced sooner or later. Fortunately, this phone call is not for questioning at all. "Hi, Professor Xue, hello."

"Well, Qiao Yu, that Yu Jian Xiao Qianqian is really you, right?"

"hey-hey..."

Qiao Yu laughed twice and was about to start quibbling, but the other person asked directly: "Have you told anyone else about the solution to the equation?" "Well, I told Teacher Lan, but Teacher Lan said she didn't understand it very well. ." Qiao Yu said honestly.

"It's normal that he doesn't understand. If someone asks about it on the forum, don't talk about it for now. Your solution can be used to write a paper that is qualified to be submitted to the first section." After hearing this, Qiao Yu immediately answered. Said: "Teacher Lan told me the same thing, but he said that I must first make sure that my solution needs to be universal."

"There is no need to be sure. Since you can solve the numerical solution of this equation, you can definitely solve this type of Diophantine equation. It just depends on how much computing power is consumed. I am sure of this for the problem I asked." "That's it..." Qiao Yu said with emotion. It seems that the difference between university professors and high school teachers is indeed very big.

"So don't mention it to anyone for the time being. If other professors call and ask, don't mention it either." "That's not true, is it? University professors still covet my little skills?" Qiao Yu said in surprise.

"Don't think too highly of the moral character of professors. Let me tell you something. Two professors were drinking together and talked about a point. They argued in depth. One of the professors wrote this after he returned home. The article was published directly. Because of this matter, another professor had been fighting with him for several years, arguing over who was the originator of this idea. A point of view that has not been widely demonstrated can be argued like this. Your kind of Do you think someone will covet a paper that can directly produce results?"

Xue Song's answer made Qiao Yu feel astonished.

The professors mentioned by the good old man seem to be good people, but from what Professor Xue said, that doesn't seem to be the case?

But speaking of it, Xue Song's answer seemed to be more in line with his understanding of people, so he immediately replied seriously: "I understand."

"Well, just understand. We can discuss this matter later. I'm making this call because of another very important issue. What are your plans for the future?" The other person asked straight to the point, catching Qiao Yu off guard. So he just Can answer honestly: "Actually, I haven't thought about it yet."

"Okay, let me ask more specifically, do you plan to go abroad?"

This time Qiao Yu answered firmly: "No, I have to take care of my mother in China." "Then you will have to choose between Huaqing and Yanbei in the future. Which one do you plan to go to?"

Qiao Yu hesitated for a while, and then asked: "...I'm actually still hesitating about this. That, do you think I can talk to these two universities about the conditions? For example, scholarships or something?" "Yes. Who told you that you can negotiate terms with universities if you have capital?"

Qiao Yu was a little confused and asked: "Is it impossible?"

"I can tell you clearly that if you only have a gold medal in the Little Li Baba Mathematics Competition, it is not enough." Qiao Yu asked: "What if I can also win the gold medal in IMO?"

"When I hang up the phone later, go check the list and results of the members who represented China in the IMO in 2005. If I remember correctly, I was one of the only two gold medal winners of the Chinese team with perfect scores that year.

Of course, Huaqing and Yanbei did contact me back then, but they just asked briefly if I had any intention to go to them. After I expressed my intention to study abroad, there was nothing more. Contacted me for the second time. Do you understand? Don’t be deceived by the messy news from the outside world. They are just for parents’ need. At least in China, the so-called top scorer in the college entrance examination is actually not true for Huaqing and Yanbei. It's no different from cabbage in the field.
Chapter completed!
