"Reprint" should allow the reader to understand the Fourier analysis without looking at any mathematical formula.Fourier analysis is not only a mathematical tool, but also a mode of thinking that can completely subvert a person's previous worldview.

The core idea of this article is:Let the reader understand the Fourier analysis without looking at any mathematical formula.Fourier analysis is not only a mathematical tool, but also a mode of thinking that can completely subvert a person's previous
