I've often wondered it fractals would be useful for plotting stability of feedback systems.
Hopefully I'll re-learn enough in the near future to try to see.
I think I still have an old fractal program around that I used to run on a PC clone. I would start the program before bed and check it in the morning!
Just an old guy (60+) who found he has forgotten more than a lot of people ever learnd, and wants to try to get some of it back.
I've been helping my granddaughter with geometry (High School) and had no problem getting up to speed, but I realized I don't remember a great deal of what I learned in college.
I bought a copy of Network Analysis by Valkenberg to try to refresh my skills.
It looks like there are many helpful people here, and lots of resource material.
