    Oh wow I’ve not had to do a Fourier transform for years but that top graphic is actually incredibly helpful for visualising what it is

        You lured me in with the nice gif of circles mapping to sine waves and then suddenly repressed memories of forbidden mathemagicks were returning to me

        Thank you for sharing. This is a great source of you already have a solid background of the basics. The visualisations are great but man, the pace from “what is a circle” to Euler’s identity… Whoof! Still looking for a Fourier for Dummies
