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.
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.
