Can you do rubber duck learning with any topic? I always wanted to learn Fourier transformations and related topics, but I completely forgot all high school and uni math, so I have to start from scratch and it seems like a huge commitement.

Sure, just type what you need to know, an idea for how to look at it and start playing.

The play part is how i get it. eg. Writing python code to generate exponents... Oh now i get why exponents loop under modulo!

I have just the book for you :-)

Buy yourself a copy of; Who Is Fourier?: A Mathematical Adventure (any edition will do) and study it. Check reviews on Amazon and elsewhere. This is a great book written in Manga style which is highly approachable.
