Encounters with Chaos by Denny Gulick… Years and years ago this was a textbook for a course that I took. I have to admit that I did not have the necessary math background to understand everything. With covid I felt it was perhaps a good time to reread it. Apparently, there is a new edition of this book and maybe if a library has a copy I would consider checking it out in the future.
There is something rather enjoyable with reading a textbook for fun. You don’t have any homework, you can focus on the important parts, and also you can skip the boring parts (including some horrible proofs). I have to admit that I did not spend that much time reading the section on 2D mapping functions.
