Please answer my question first, and then read on.

I asked myself such a question when I was in the second grade of primary school.

Later, I studied mathematics as an undergraduate in Tsinghua. A big reason for choosing this major is that I hope to have an opportunity to give an answer to my childhood questions.

Undergraduate students have been thinking about this problem and discussing it with their classmates, especially when they are freshmen. I want to say that if you are not a math major and have never studied pure mathematics, you will have a taste of real mathematics. Engineering only regards mathematics as a tool, and mathematics studies the tool itself. When we were freshmen, we spent a lot of time trying to solve a problem. What are numbers? What is 1, 2, 3, pie, etc.

A wonderful question: why can the nature we live in be described so accurately by mathematical formulas? simple

F=am。

Concise and precise (with some modifications under the theory of relativity).

There is a saying.

He wrote all the laws of nature into mathematical formulas, and then created geniuses like Newton and Einstein to discover them. If you have the opportunity to learn more physics, such as Schrodinger equation and wave function, you will understand the meaning of this sentence better, which is also the pursuit of many physicists.

Talk about my understanding of mathematical beauty. The beauty of mathematics has two aspects. On the one hand, it is the beauty of watertight logical deduction. A building built with mathematical logic will last for thousands of years. Pythagorean theorem was proved in this way 2000 years ago, and it is still correct after 2000. On the other hand, the conclusion of mathematics itself is beautiful, and there are also beautiful results in number theory. If you study probability statistics, the central limit theorem is a wonderful conclusion. Of course, you need to really understand it, not just read the theorem.

The beauty of this mathematical conclusion sometimes makes me wonder whether God created mathematics and waited for people to discover it, or whether people invented mathematics themselves. This problem has been bothering me for some time. I discussed this issue with a foreign Christian professor. In Christianity, human wisdom is given by God. He believes that God has given mankind wisdom to create mathematics.

I am studying abroad now and have been baptized into Christ. I asked three questions before I was baptized, one of which was mentioned above. The professor's answer inspired me a lot.
