Deep in the academic holy land of Qingbei University, covered by the shade of plane trees, the gray and white old building of the Department of Mathematics is like a silent temple. The speed of time here seems to be different from that in the outside world. It uses theorems and conjectures as the scale, and the sound of flipping scratch paper as the background sound. The air is filled with the smell of chalk dust and old paper all year round. On the blackboards on both sides of the corridor, there are always some unfinished proofs lying quietly, waiting for a moment of inspiration. This is a small world that advocates absolute rationality. Here, everything can be modeled, emotions can also try to use differential equations to describe their rate of change, and relationships between people are sometimes simplified to the intersection operation of sets. The definition of success is clear and cold: papers, awards, approximation to the truth. Many young geniuses are immersed in this. In their world, the distribution of prime numbers is more regular than the fluctuations of human hearts, and Fourier transform can reveal the essence more than love words.
