I just watched the first video, but compared to almost all similar videos (about the same length, teaching math) I found it to be SUPERB. It explains things extra clearly by explaining the idea of wrapping a periodic function around the circle, and accompanying each statement of the narrator with the appropriate pictures. Does anyone know who is responsible for this video? —Dan Henry Baker wrote: ----- I'm curious as to what others think about this Fourier Transform video (1/26/2018). http://www.3blue1brown.com/ https://www.youtube.com/c/3blue1brown -----
