I spent some good times exploring deterministic chaos.

Mathematica had sound outputs for the logistic map. I remember one could distinctly hear the octaves progression, then noise, then a fifth. I remember making a video overlapping the sound and the cobweb plot to "see" what I was hearing.

Instead of studying calculus, I fell for the trap of trying neverending, eardrum busting, iteratibly non-converging functions.

My study method was pretty chaotic.
