"Senior Fan is awesome."

"Did Zhao Shen attend the annual academic meeting of the Mathematics Society this year? Is it possible that he came to receive the award?"

"I was discussing with my colleagues whether Zhao Shen will be among the winners of the Chen Shengshen Mathematics Prize in China this year. Now it seems that there is definitely one."

"I thought you ran away to the United States."

…

The senior Fan mentioned in this comment was the one who came to attend the annual meeting of the Chinese Mathematical Society and won this year's 13th Zhong Jiaqing Mathematics Award, Fan Yuwei.

In fact, Fan Yuwei and Zhao Xiancai are alumni, because he studied at both Yuanpei College and School of Mathematical Sciences of Peking University, but his main research directions are numerical solutions to partial differential equations and the application of deep learning in computational mathematics.

Zhao Xiancai's research is somewhat different.

After graduating from Peking University, he went to the United States to engage in postdoctoral research in the Department of Mathematics at Stanford University.

…

"Aren't you studying at the University of Michigan now? Is this some kind of awards event in the United States?"

"I went to Zhao Shen's place to check some things, but he didn't post anything."

"Zhao Shen can't post a few updates a year. It's normal that he doesn't post any updates, but it's abnormal that he does."

…

In addition to Fan Yuwei’s post, which had many comments, there were also many comments on posts posted on different social platforms by several other recipients of the 13th Chung Jiaqing Mathematics Prize who took photos with Zhao Xiancai.

In any case, since they came to participate in this year's academic annual meeting of the Chinese Mathematical Society and also won this year's Zhong Jiaqing Mathematics Award, their majors or careers are more or less related to mathematics.

In this case, the updates they posted, especially those posted in Moments, were naturally commented upon by many people in the field of mathematics.

Even for those updates posted on other social platforms, due to Zhao Xiancai's wide popularity, there are still many comments from netizens in non-mathematical fields.

As for Zhao Xiancai, after he had signed the names of the PhDs or postdocs who were older than him and left, Yang Gang on the side smiled and said to him: "Haha, to be honest.

, this is the first time I have seen these outstanding students come to a scholar to get his autograph like they are star-struck, and they are still such a young scholar like you.

I heard Professor Gong say a few days ago that you joined Professor Liu Yuelin from the School of Engineering at Princeton University to conduct a research project on perovskites?"

After smiling and briefly expressing emotion to Zhao Xiancai about the young students' enthusiasm for Zhao Xiancai, Yang Gang asked him again.

"Well, actually, the research on perovskites that Professor Liu asked me to participate in is similar to the research that I participated in before with Professor Gong.

It’s just that Professor Liu’s research is on the aging of perovskite solar cells, and my role is to analyze their relevant experimental data, and to build and continuously improve the relevant mathematical models.”

Zhao Xiancai explained to Yang Gang without much thought that after all, the topic Liu Yuelin was researching was not a military secret or a corporate secret. Even if it was a corporate secret, it was not such that even the title could not be revealed.

Even if Zhao Xiancai didn't say it, Yang Gang could have found it on the Internet, or he could have known it by asking Professor Gong Qi.

Moreover, Zhao Xiancai estimated that since Professor Gong Qi told Yang Gang about his participation in Liu Yuelin's research project on the aging of perovskite solar cells, he must also have told Yang Gang about the content of Liu Yuelin's research project.

"Oh...that's good..."

After hearing Zhao Xiancai's explanation, Yang Gang said this.

However, Zhao Xiancai could obviously tell from the expression on Yang Gang's face. After Yang Gang answered this, he looked hesitant to speak. It was obvious that he still had something to say to himself.

Sure enough, as Zhao Xiancai had guessed, Yang Gang was silent for a brief moment after briefly responding to what Zhao Xiancai said, and then continued to say to him: "You are very smart. I have always felt that your intelligence is only reflected in

Mathematics.

After all, from when you first participated in the National High School Mathematics League, to when you won the gold medal in the International Mathematical Olympiad with perfect scores, to when you published your first paper in your life, "Singular Integral Differential Equations in the Riemann-Hietzschule" shortly after entering college.

Solvability' in Hulbert's problem, and finally to Goldbach's conjecture that you solved not long ago.

These achievements of yours all show people your amazing talent in mathematics...

But……

If I think about it carefully, I find that your growth process from a student who often slept in class and had poor grades to being number one in the class was not only a short period of time, but also did not seem to have any shortcomings.

If there are any shortcomings, it is those things in high school liberal arts.

However, I don't believe those are your shortcomings.

I believe it’s just that you didn’t pay enough attention to it. With your strength, no matter what field you chose at the time, you would probably be able to achieve the same impact you have in the field of mathematics now..."

This time Yang Gang and Zhao Xiancai talked a lot, but until they sat down, Zhao Xiancai didn't hear what Yang Gang wanted to say.

He was a little confused as to why Yang Gang suddenly said this to him today. He was only twenty years old now. There was no need to summarize his previous life so quickly, right?

"...So, actually, when I learned that you were planning to change the main content of your research from mathematics to physics, this is what I really thought in my heart.

If you are like Edward Witten and are only planning to engage in theoretical physics research and use your knowledge and talent in mathematics to study content similar to string theory, I think it’s okay. After all, you still haven’t fallen behind in mathematics.

.

But if you plan to do research in applied physics, or in a field that is a bit far away from mathematics like perovskites, I think you are very likely to fail.

But in this case you will eventually come back to mathematics, so I still think it's okay.

But now, I feel that if you really want to engage in research in the field of applied physics, with your intelligence, whether it is perovskite solar cells or computer-related technologies, it is very likely that there will be major breakthroughs."

Even when Yang Gang said this, the doubts on Zhao Xiancai's face did not disappear. On the contrary, they increased a lot.

"Yang..."

"If you have any shortcomings, it's that you trust people too easily.

Therefore, if you have some ideas for certain research in the future, don’t always be so anxious to tell others.

in addition……"

Just as Zhao Xian was about to say something, Yang Gang interrupted him and continued to speak to him.

Only then did Zhao Xian know what Yang Gang was going to say to him.
