From all-round academic master to chief scientist

Some people say that college life is like a cup of boiled water, bland and tasteless, but for Lin Xiao, he realized that this cup of boiled water can make him feel fulfilled.

Without the interruption of others every day, Lin Xiao can completely swim in the ocean of knowledge and feel the pleasure of constantly enriching his brain.

As for the group meeting, it was carried out as usual on Friday of the second week. However, this week's group meeting already focused on the exploration of physical meaning, which was what was originally said, establishing an incompressible elastic dynamic system. The two professors clapped their hands and decided on something that Lin Xiao couldn't understand.

For example, Lin Xiao knew the incompressible isotropic Hookean elastodynamic system, which is the Hookean type. As for Hooke, he was naturally the one who proposed Hooke's law. He also knew other terms, such as incompressible. What about isotropy and so on, but when combined, he lacks relevant knowledge reserves.

Of course, Tang Qing didn't care about this. After all, he only needed Lin Xiao to be able to play a role in mathematics, and the project time was still long. Their project had only started for a few months. Of course, the research cycle of a project was very long. , Otherwise, where would they have so much time to spend money?

After the day's group meeting, Lin Xiao left the conference room and walked out of the research center. When he was about to go to the library, he suddenly received a phone call.

"Huh? Is this from Professor Xu Ji?"

Professor Xu Ji is also a mathematics professor at Beijing University. Speaking of which, Lin Xiao has not seen him for so long.

So he answered the phone and said with a smile: "Professor Xu."

"Xiao Lin, have you enrolled in school now?"

"Yes, speaking of which, I haven't seen you in school for so long. Aren't you in school these days?"

"Haha, I went to a mathematics conference some time ago and just came back a few days ago. Where are you now?"

"I'm in the Mathematics Research Center now. I just came out of it and was about to go to the library."

"International Mathematical Research Center?"

"Yes."

After listening, Xu Ji was silent for a while, and then said in a serious tone: "Come to my office now, and I will tell you a few words."

Hearing Professor Xu Ji's tone, Lin Xiao couldn't help but be startled, what's going on?

But the call had been hung up, and he had no choice but to go to Xu Ji's office.

Soon, he arrived at the science building and found Xu Ji's office. He had been here before and naturally he had not forgotten it.

Knocking on the door, "Please come in" came from inside.

Lin Xiao opened the door and entered, and saw Professor Xu Ji sitting inside, as well as several of Xu Ji's graduate students.

"Professor Xu."

When Xu Ji saw him coming, he stood up and invited Lin Xiao to sit on the sofa next to him.

"What do you want from me?"

Xu Ji looked serious and said, "Did you go to the research center to do any research?"

"You have to answer honestly. If someone asks you to work as free labor, tell me who it is and I will trouble him."

"Don't worry about who the other party is, Professor Lao Shizi. We have a lot of bullshit at Beijing University. Normally I don't bother to scold such people. If someone really asks you to do that kind of thing, then I have to talk to him."

The reason why he asked Lin Xiao to come so seriously just now was because he was worried that Lin Xiao would be used as free labor by other professors. Of course, this free labor should refer to 'brain power'. After all, who doesn't know that Lin Xiao is good at mathematics? It's amazing. Maybe there is a professor who is not good enough and asks Lin Xiao to help with research?

Moreover, the International Studies Center mainly conducts project research, and they will definitely not find an undergraduate for no reason, let alone Lin Xiao.

If any professor really asked Lin Xiao to help him research a topic based on his status, then he would really point his finger at that guy and scold him. He would just squeeze those postdoctoral fellows, but also squeeze Lin Xiao?

This is not only harming people, it is also harming their school.

Hearing Xu Ji's words, Lin Xiao's heart warmed slightly, and she felt dumbfounded at the same time.

Hearing Xu Ji's tone just now, he thought there was something bad going on, but it turned out to be because he was worried about this matter.

So he smiled and said: "Actually, there is no such thing. It is Academician Tang Qing's project. I took the initiative to participate in it. I am somewhat interested in physics."

"Academician Tang? Oh, that's okay. I thought you were called over by those incompetent people who came in through connections."

Professor Xu Ji was relieved when he heard that Academician Tang was looking for Lin Xiao.

Even if Academician Tang Qing asks Lin Xiao for help with a project, he will definitely not say that he is squeezing free labor. After all, he is an academician and there is no shortage of labor. Moreover, Academician Tang Qing treats his own people quite well, so there is no need to worry. That kind of problem.

As for Lin Xiao's study of mathematical physics, Xu Ji didn't think there was anything wrong with it. After all, he also studied this thing himself, so of course he would not have such disciplinary bias.

Then he smiled and said: "Why are you interested in studying mathematical physics now? Could it be that mathematics is not difficult for you?"

Hearing Professor Xu Ji's question, Lin Xiao couldn't help laughing: "How is that possible? I don't know many problems in mathematics. I just have a little interest in physics."

"Haha, I hope so. If mathematics wasn't too difficult, I wouldn't study mathematical physics."

Xu Ji sighed, the more difficult the subject of mathematics is to learn, the more difficult it becomes. When mathematicians find themselves rushing into the "other world" of pure mathematics, they will always find that this "other world" is so special. It’s not something people can tolerate, so they choose to leave here and enter the physical world.

There are many such people, and there are also many who have made great achievements in physics.

"They are all doing academic research, so there is nothing different." Lin Xiao said with a smile.

"Haha, look, you have answered two questions in the field of prime numbers, and now you are not considering developing in the field of prime numbers? Twin prime number conjecture, Goldbach's conjecture or something?"

When Lin Xiao heard about Goldbach's conjecture, he couldn't help but think of the problem he had seen in a mathematics textbook when he was a child.

At that time, he didn't even understand the question. He only knew that it was a 1+1 question, but he just didn't know why it was a 1+1 question. He just thought that 1+1 is equal to 2. Does this still need to be proved?

But now, he has a deep understanding of this problem.

"If I have a chance in the future, I will try it."

he said.

Hearing what Lin Xiao said, Xu Ji couldn't help but raise his eyebrows.

He had an inexplicable feeling that Lin Xiao might succeed?

No longer discussing this issue, Xu Ji asked as if inadvertently: "By the way, are you about to choose a mentor?"

Lin Xiao was stunned for a moment, and suddenly remembered what was said in the class group before, and it seemed that they were indeed going to start selecting a tutor.

"Yes." He nodded.

Xu Ji said with a smile: "Which tutor are you going to choose? Our Math Institute has many options to choose from."

Suddenly he remembered something and said: "By the way, has Academician Tang told you about selecting a mentor?"

"That's not true."

"That's good." Xu Ji seemed to be relieved, and then as if he was afraid that Lin Xiao would misunderstand something, he explained to him: "Academician Tang is basically working hard on mathematics and physics now, although you are interested in mathematics. You are a little interested in physics, and I support this, but you should still continue to study more in mathematics. Your talent cannot be wasted, so you should also choose some tutors who mainly focus on mathematics."

"For example, I plan to go to France in January next year to attend the Bourbaki seminar. Do you know about the Bourbaki seminar? If you are willing to go then, I can take you with me - of course, you You have to learn French before that, because they all discuss it in French.”

Hearing Xu Ji's words, Lin Xiao raised his eyebrows.

Why does Xu Ji's words sound like... self-recommendation?

However, compared to other things Xu Ji said, Lin Xiao was more interested in the Bourbaki seminar.

He had already heard about this thing.

The Bourbaki seminar has a close relationship with the well-known Bourbaki school in mathematics. The Bourbaki school’s status in mathematics is extremely important, and their contribution to the mathematics world is also considerable, bringing great influence to the development of mathematics. Big motivation.

At the same time, it was the roots and development of the Bourbaki School in Paris, France, that also provided considerable assistance for Paris to become one of the world's mathematics centers. Even now, the economic strength of the United States has attracted many mathematicians to take root there, especially It is Princeton University, but it still does not affect France's status as a holy place in the hearts of mathematicians.

To this day, Paris, France is still home to the largest number of mathematicians in the world.

The Bourbaki seminar, also under the influence of the Bourbaki school, was started in 1948 and continues to this day as a lecture format. It does not refer to a class with fixed members, but invites Those Bourbaki and other famous mathematicians, plus some students, then went to Paris, France, to discuss it.

This form of discussion class has also influenced various current discussion classes. It can be said that the current discussion classes were all established under the influence of Bourbaki’s discussion class.

Lin Xiao asked curiously: "Will the Bourbaki seminar be held in January next year?"

Hearing that Lin Xiao was interested in this, Xu Ji smiled and said: "Yes, it will be held in January next year, but it usually holds four events every year. There is already one next month, but I plan to participate in January next year. That scene.”

"If you want to participate, just apply there and they will probably be willing to agree. But again, you need to learn French. Otherwise, you may not understand it after you go there."

Lin Xiao nodded. He was indeed a little interested in this seminar, but after all, he had to learn French first.

Due to France's status in the mathematics community, there are also many mathematicians who master French and English.

"I'll think about it later."

"That's okay. Of course, it's best to decide early so that you have time to learn French. It's still a bit nervous to learn some daily vocabulary and mathematics in three months."

Xu Ji smiled and nodded, then asked: "Then do you have any ideas about choosing a mentor?"

Lin Xiao couldn't help but feel funny when she heard that Xu Ji mentioned the mentor thing again, and at the same time, she was sure that the old professor wanted to be his student.

He smiled and said: "If you don't mind, I hope to learn under your hands when the time comes."
