I am impressed by your way of turning abstract math into vivid images. It seems to be informal or unserious to this great subject(just my opinion). But maybe it does work to some people. I have some questions about it. It seems that the math contents you turn them into these pictures are a little simple. I mean how can you turn some complicated math concepts into visualization, such as calculus, maybe I haven’t read some of your other articles. In addition, do you have some other resources or published contents like this that you have finished? It seems to be very interesting.
