Hearing Xu Chuan say, "It's not that difficult," Zhang Weiping couldn't help but twitch the corners of his mouth.

What should I do if he wants to hit someone?

Although the knowledge used to solve IMO competition problems is basically limited to high school, skills and experience cannot be locked.

In this case, it takes him more than an hour to solve a problem with decades of mathematical knowledge and experience. Is this called not difficult?

What he said... was simply too pretentious...

All right.

For this person, it may not be difficult.

After all, he has solved three of the seven millennium problems by himself. In today's mathematics community, there may be some people in a single field who can compare with him, or even surpass him.

For example, Faltings and Deligne in the field of algebraic geometry; Sarnak in the field of number theory; Perelman in the field of topology, etc.

These top experts can still compare with this one in their respective fields of proficiency, and may even be ahead or surpassed.

But looking at the overall situation, I am afraid that except for Terence Tao who may be able to barely keep up and dabble in so many fields at the same time, it is really difficult to find another mathematician who can be proficient in so many fields of mathematics at the same time.

What's even more abnormal is that in addition to the field of mathematics, he has also made considerable achievements in almost completely different fields such as physics, materials, astronomy, etc.

To be honest, can human talent really be so powerful?

It's hard not to wonder whether there is a quantum computer hidden under this skin.

...

Standing opposite the two of them, Xu Chuan didn't think much about it.

He was still a little surprised when he heard that Liu Jiaying was the only girl to get perfect scores in the entire IMO.

IMO, the last big question on the exam was asked by him, and it was indeed not too difficult in his opinion.

If he really had to ask a difficult question, he was sure that no student in the entire IMO competition could solve it.

But that doesn't make any sense.

For a mathematics competition, the content of the assessment is not how much knowledge these students have mastered, but how they use their limited knowledge to solve problems.

Mastering knowledge is only the foundation, using knowledge to solve problems is creativity.

However, this does not mean that the problem is so easy to solve.

The questions he asked do not require the use of college knowledge, what you learned in high school is enough.

But the skill required to solve that problem is not low, it can even be said to be high.

To be able to solve the problems he asked, talent and hard work in mathematics are absolutely indispensable.

Xu Chuan was indeed a little surprised when such a genius appeared among his friends.

But considering Liu Jiaxin's talent in mathematics, it is normal.

It's not that these things are inherited genetically.

In fact, genes are not necessarily 100% effective. No one can guarantee that an older brother or older sister will have amazing IQ, while a younger brother or younger sister will also have excellent intelligence.

But if there is a brother or sister around you who is talented enough in a certain way and can bring experience to the younger siblings, as long as the brother or sister is willing to teach, it is absolutely unimaginable for ordinary people.

Just like him and Xu Xiao.

When he was in middle school and high school, he taught a large part of Xu Xiao's extracurricular tutoring, homework, learning problem-solving ideas and techniques every winter and summer vacation.

These things have brought Xu Xiao more experience on the road of learning, allowing her to learn more easily and stand out among middle schools at the same level.

This is also the reason why relatively wealthy families are more likely to produce outstanding geniuses.

Because their parents, or their family conditions, are capable enough to find an excellent teacher to do this job.

In relatively poor families, most children face parents who have not finished junior high school or high school, and teachers who have to take care of entire or even multiple classes in school.

If you are not talented enough to stand out and receive extra attention and guidance, otherwise it will be very difficult to get an 'extra' and detailed guidance.

And sometimes, middle school and high school teachers may not have this ability.

This 'theorem' is not only applicable to learning, but also applies to many other broad fields.

After all, the most precious thing for a person is not wealth or status... but time.

...

After sizing up Liu Jiaying, Xu Chuan smiled and said, "If you are willing, you can come to my place..."

Opposite me, Zhang Weiping raised his eyebrows and interrupted: "I said, isn't it a bit unkind of you to do this? I finally accepted an undergraduate, and you just want to poach him."

After a pause, he sighed again, and then said: "Forget it, if you really want it, just take him away. It will definitely be better to study with you than with me."

After being interrupted for a while, Xu Chuan also came to his senses, thought for a while and then said:

"Forget it, let her study with you, Academician Zhang, in college. I have a lot of research on hand here. You may not learn anything by following me in college. It's more important to lay a solid foundation."

"If she waits until she gets a master's degree or a doctorate, she can apply to Nanjing University."

"Only if you are willing."

He looked at Liu Jiaying and said the last sentence.

Originally, he wanted to poach this senior's sister directly, but after being interrupted by Academician Zhang Weiping, he gave up the idea after thinking about his time.

He didn't have much time to guide her during the foundation-laying stage of college. Instead of poaching her like this, it would be better for her to study with Academician Zhang Weiping during the undergraduate stage.

When she reaches the master's or doctoral level, if she is willing, he will still be happy to accept this student.

Of course, the premise for these things is that she is willing.

If Liu Jiaying didn't want to, he couldn't force the person to come over. There was no need.

This chapter is not over yet, please click on the next page to continue reading! Opposite, Liu Jiaying blinked, met Xu Chuan's gaze, and then looked at his mentor.

After feeling the encouragement and recognition from those kind eyes, she nodded and said obediently: "Thank you, Academician Xu, I will study hard."

Having the opportunity to study with a leader in mathematics is a rare opportunity for anyone who is interested in making further progress in mathematics.

And this person seemed to be very special to her sister, which made her very curious.

After a pause and hesitation, she finally said, "Xu...Academician Xu, can I give you some credibility?"

Xu Chuan smiled, took out his mobile phone from his jacket pocket, and sent his mobile phone number to her with added authority.

"This is my phone number. If you have any questions or study problems, you can send me a message or call me. You don't have to worry about disturbing me, and you don't have to be so polite."

After a pause, he looked at Zhang Weiping and said with a smile: "Academician Zhang, I won't disturb your meal. Let's go now. We'll talk when we have time."

Zhang Weiping said with a smile: "Go ahead, I have time to go to Sun Moon (Fudan) University after returning to China."

Xu Chuan waved his hand, turned and left.

.......

After returning to his room from the restaurant, Xu Chuan took a shower, turned on his computer, and connected to the hotel's wireless network.

He unexpectedly met an 'acquaintance' in St. Petersburg. He really didn't expect that he would have called his senior sister to come with him.

He clicked on the prestige and found senior Liu Jiaxin's prestige. He sent a message: "Guess who I met in St. Petersburg?"

After sending the message, he realized that there is a time difference of about five hours between St. Petersburg and China. It should be early morning in China and the other side should have gone to bed.

But just when he was thinking about turning off his prestige and going to review the report process of this mathematics conference, the news from the other end came back.

"Jia Ying?"

Seeing the reply, Xu Chuan raised his eyebrows, smiled and typed: "Has she told you?"

"Well, she just sent me a message and said she met you."

Xu Chuan smiled and typed: "Speaking of which, you already knew that your sister would attend this mathematics conference, right? Why didn't you tell me?"

"She is an adult and can take care of herself."

Xu Chuan: "You treat me like an outsider, you're too polite. Forget it, let's not talk about it. It's already early morning in China, why haven't you fallen asleep yet?"

"I'm still with the company."

"Why are you still working overtime at this hour? What happened?"

"There are some problems with the algorithm of the artificial intelligence program, and I will solve them as soon as possible."

Looking at the message that came back on the screen, Xu Chuan was stunned for a moment and typed: "It's not too late to do this tomorrow. Go back and rest early. You are an adult too. Don't make me worry."

There was silence on the other side for a few seconds, then a message came over.

"Hmm~."

.......

The next day, early morning.

After Xu Chuan woke up from bed, he opened the heavy blackout curtain.

Before seven o'clock in the morning, it was already bright outside.

In the winter in St. Petersburg, the sun rises very late and sets very early, and the daylight hours may be less than six hours a day.
