Once in a while, #veritasium creates a video that is stunningly good. This one on #FFT and #nuclear #disarmament was one.

FFTs are something I wish I'd learned in school, and have never taken the time to really learn. This video was the best overview I've seen yet of #fourier transforms. And it also covers the application of FFTs to nuclear treaties, as well as a connection to #Gauss I'd never heard before.
