Today when reading useless articles on 知乎, I found a pretty interesting problem discussing the inherent relationship between physics and mathematics. It really echoes my thoughts recently. Personally, I realized this magical connection when I started to learn physics Olympiads, in which q …

In last article I talked about how to use only one simple spring force to set up a differential equation and solve it to give the dynamics of SHM, which is a typical projection of uniform circular motion. Forces that follow the Hook’s Law seem to be very special in real world. There a …

Introduction Recently, when we studied oscillation or SHM —- fundamentals of waves and periodic motions —- Birdy(鸟哥) asked me a question that “seemed” to be so obvious: why the equation of oscillations are derived from the circular motion? Here are some explanation …
