In 2063, the People's Daily published a series of special articles on the centenary of the birth of the father of modern Chinese science, famous mathematicians, physicists, chemists, biologists, musicians and educators.

The People's Daily immediately published the full text of this dialogue, which provided an important basis for people to understand the thoughts and concepts of Junxin in the early days. The following is an excerpt from one of them.

Reporter: Junxin, hello. According to the professor at the school, your article was published in Nature, congratulations to you for that.

Junxin: Thank you.

Reporter: We are all curious, you are a mathematics student, but the results you made in Nature are in chemistry, how did you come up with it?

Junxin: Gauss, the prince of mathematics, once said that "mathematics is the queen of natural science, and number theory is the queen of mathematics", but very few people know that Gauss also said that "mathematics is the queen of natural science and the servant of natural science". In Gauss's second sentence, everything I do is based on the study of mathematics.

Reporter: Can you elaborate on that?

Junxin: This was last semester. Since I solved one of the more complex conjectures in mathematics, the rigorous Mizuki was kind of open to me, and I had the privilege of being free to attend classes. Once, I was working in the all-night study room to solve a problem all night, and I felt that my energy was good, so I went to class. But I didn't notice that I was in the wrong classroom, and I was in the crystallography class of the chemistry department. At that time, the professor asked me the question of explaining the meaning of crystals, and I didn't know much about it, so I omitted a little bit of explanation, but explained it according to the thinking of a mathematician. At that time, the explanation was rejected by Professor Chen, and of course I was a little unconvinced, so I made a breakthrough with the periodicity in the definition of crystals, cooperated with Penrose's two-dimensional structure, and then triggered the study of quasicrystals.

Reporter: Looking back now, what kind of thoughts did you have at that time?

Junxin: I don't have any ideas, but I have some feelings. Our Mizuki University has always been known for training engineers, and it is natural that we are rigorous in teaching, but it is surprising that Professor Chen was able to come up with my ideas at that time. This shows that the teachers in our school actually have a very cheerful personality, are not so stubborn, and are easy to accept new things. It is my pleasure.

Reporter: I remember that your article was published in Nature in the form of a supplement, what do you think is the reason why the strict Nature published your article in the form of a supplement?

Junxin: Actually, I just said the answer. Mathematics is the queen of natural science, and since the queen has already spoken, how can there be no pass?

Reporter: Hehe...

Junxin: Of course, it's just a joke, but that's not wrong. Because I reasoned from a mathematical point of view, there are many applications of mathematics in the article, including a lot of data analysis, model construction, geometric structure derivation, etc., which has a mathematical foundation. If the results of a new natural science study can be expressed in strict mathematical models or formulas, then its rigor and accuracy can be ensured to a large extent, so this article is rigorous enough.

Reporter: What else?

Junxin: In addition, the article is cutting-edge enough, and it can almost be said that it has created a new branch of chemistry. The concept of quasicrystalline is not the first time I have proposed it, a professor of chemistry at Princeton University has already proposed this concept, but what I did was to establish this incomplete concept thoroughly and give it a complete mathematical model, which is the first in the history of chemistry.

Reporter: So you found this quasicrystal, do you have any plans for the future?

Junxin: After my discussion with the school, I decided to set up a special quasicrystallization laboratory with a part of the school's public funds, and the team leader of the laboratory project team has been recruited, and the early work will start in the near future.

Reporter: Leading a teacher as a student, it's a bit...

Junxin: Hehe, I know what you're going to say, but it's nothing. You know, I'm already a researcher here at the Institute of Mathematics. In the research institute system, a researcher is equivalent to a professor. The other two project leaders are associate professors, and strictly speaking, their titles are actually slightly lower than mine. In this way, there is nothing wrong with it. In addition, this project is jointly carried out by the Department of Chemistry and the Department of Mathematics, and I am the head of the Department of Mathematics, so I may be a little lacking in qualifications, but I think other aspects should be enough.

Reporter: I heard that you have been writing a textbook recently?

Junxin: Strictly speaking, it's not a textbook, it's just a reference book for mathematics.

Reporter: How did you come up with the idea to write a book like this?

Junxin: In the beginning, because I published a mathematical paper on Modell's conjecture, but it was published in the Annals of Mathematics, I wrote to some of the world's top mathematicians. For example, Grothendieck, Beckett, Griffiths, Deligne, Chen Xingsheng, Professor Yau Chengtong and so on. But then I don't know what happened, and I received more and more letters. But a lot of them told me that they solved a famous problem and asked me to help post articles or something.

Reporter: Do they really have a solution?

Junxin: No, it's all nonsense. One of the letters said that he had five ways to prove Fermat's theorem. Wo Zi is dismissive of this statement. In today's world, I dare to say that when it comes to understanding Fermat's theorem, I think there should be no one above me. But even if I want to solve the problem of Fermat's theorem completely, I have to do it, put aside all the work that has nothing to do with the proof of the theorem, and spend at least seven years or more dedicated to proving this problem, and I don't know if I can succeed. He said that there were five ways to prove Fermat's theorem, and I was really dismissive.

Reporter: Why? This is also their achievement, right?

Junxin: Because if someone can really make such a result, then you can send the manuscript directly to the journal and magazine, even if you don't go through me. Because the really top research results, everyone knows whether they are true or not. But I don't believe he was able to make five ways to prove Fermat's theorem. If this is the case, then he is not only above all mathematicians for nearly 300 years, but even before mankind enters the age of intelligence, no one can surpass it. If we say respect for his work, then I would say that if we respect his work, then who will respect the work of mathematicians who have built a complete mathematical system and stood the test of time since Euler, Gauss, Riemann, Poincaré, etc.?

Reporter: So you wrote that reference book?

Junxin: That's right. I officially named this book "Mizuki University Mathematics Guide", which includes an introduction to most of the achievements of mathematics, sub-disciplines, an introduction to the results of basic mathematics research since the 20th century, the direction of mathematical research in the next 20 years of the 20th century, and an introduction to some mathematicians and their achievements and works. It is a guide-type book for popularizing mathematics education and professional knowledge.

Reporter: Where did the book begin?

Junxin: Originally, I wanted to write a book that I could read at a high school level, but in the end, I found that I couldn't do it, and if I wanted to read the professional part of the book, I had to have undergraduate professional knowledge.
