"It's a great honor to meet you in this new class, and it's a great honor to meet so many people in this class, and to be honest, it's a bit of a surprise to me. I didn't think there were so many people coming to my class! Junxin stood on the podium with a smile on his face and said to the students in the classroom that were almost half seated.

"I think that since you have chosen my course as one of your elective courses this semester, there will be no shortage of understanding of me. But before I do that, I want to introduce myself. My name is Junxin, I am from Shuimu University in China, and I am a sophomore exchange student in the Department of Mathematics at Princeton University. Do you have any questions about this? After saying that, Junxin glanced under the podium.

In fact, Junxin himself knew that more than half of the students in the audience chose their own course only for credit, although most of them knew him and knew his achievements. However, it is not recognized that his achievements are recognized as his ability to teach. To a large extent, the lectures are just for those 2 credits. However, Junxin doesn't care much about this, although he doesn't think that the fancy that he can say attracts most students, but at least he won't mislead people's children. Science is different from liberal arts in that science is a systematic discipline, and boring is inevitable, so science will always make people feel bored, no matter how funny it is, it is impossible to change the boring nature of science. Only those who can truly endure loneliness can learn the real thing.

"Those who know me may know that although I am from the Department of Mathematics, in fact, my research direction is not limited to mathematics, physics is also a subject that I am good at. Some of the studies I have done on unified field theory on superstring theory have been published one after another, and the response has been quite good. In addition, I also have a little bit of research in chemistry, and you may know that one of the hottest research directions in chemical crystallography - quasicrystallography is a project that I completed last year. Also, when I was traveling to Mit with our Princeton varsity basketball team not long ago, I met Professor Alan Paley and gave a talk on quantum communication technology at Mit, which was based on some of my thoughts on the development of electronic computers. ”

"I beg your pardon, the reason why I said so much is not because I want to show off anything, it's not necessary." Junxin said with a calm face, "These things have become a thing of the past for me. And the reason why I still mention these things is because of the course that we're going to talk about today. ”

Looking at the students below who began to look more and more serious, the corners of Junxin's mouth couldn't help but show a smile: "The course we are going to talk about today is the latest course created by Princeton, and it is also the first course established after looking at all the universities. The course of Mathematics Synthesis is, in my opinion, bound to become a landmark subject in Princeton in the future. ”

"Of course, if you think I'm bragging, I can't prove it to you. However, what I said is not unreasonable: the most powerful discipline in Princeton is undoubtedly mathematics, and mathematics is the mother of natural sciences, and we have creatively proposed to take mathematics as the center, driving physics, chemistry, computer science and biology, and bringing you a divergent way of thinking from multiple perspectives, which will be the most important feature and role of this discipline. How to build an interdisciplinary way of thinking will be something you will need to think about in the next five months. ”

"Teacher, what is the assessment method for this course?" A student asked, holding up his hand.

Junxin glanced up at him and asked with a smile, "I guess you're a biology major, right?" ”

"My name is Floyd, I'm a sophomore majoring in biochemistry, how do you know I'm from biology?" Freud asked, surprised.

"It's not hard to guess!" Jun Xin shook his head and replied easily, "As I just said, the main purpose of this course is to cultivate your interdisciplinary way of thinking!" ”

"If you're a math student, you're not going to ask that question, you're going to ask me what the cut-off score is for passing. Chemistry students may ask me how I can pass the exam. Physics students would ask me what I would take in the final exam, etc., and only biology students would ask me this question. Junxin said with a smile.

"Actually, whether it is physics, chemistry, mathematics and computer science students, including Freud's biology, the ultimate goal of the questions they ask me is to pass the assessment, but because of the different ways of thinking under the influence of their respective disciplines, the way of asking questions is also different. Mathematics students are naturally sensitive to numbers, so what they care about is an accurate number, or a question of the logical relationship of mathematics, so they will ask the question of the score line. Chemistry departments, on the other hand, are concerned with the application problem, that is, how to use it, so they are more practical, so they will ask how to do it. ”

Speaking of this, Junxin glanced at the following, and did not continue to speak, but changed the conversation and said: "In fact, we are learning in the same atmosphere, whether it is physics, chemistry, computers, or even biology, we are subject to the same teaching atmosphere and external environment, and the reason why we have formed different ways of thinking is that we have different ways of thinking because of the characteristics of our respective disciplines. ”

Of course, I am just giving an example here to illustrate that different disciplines have different thinking and have their own characteristics. Since you have chosen this course as your elective, you have chosen to have a certain understanding of other subjects. In the next period of time, I will guide you to understand each other in different disciplines through the medium of mathematics. Junxin said with a smile.

Of course, the topic is a bit far away, so let's return to Freud's question. I have very low requirements for you, I don't need you to take any exams, and I don't need you to do a lot of exams, this is not necessary. As long as everyone gives me a copy before the end of the semester, about using mathematical thinking to solve a paper or physics, or biology or chemistry, mathematics students are also required to do the same, but you need to use the thinking methods of other disciplines to solve a mathematical problem, I will grade according to the specific situation of the paper, and you can get credit if you pass the minimum standard, do you have any questions? ”
