Pretty good, but I would’ve liked to see some discussion of the behavior of sin ax sin bx, and the fact that its long-term average is 0 except when a = b or -b. For that matter, I think the physics of sympathetic vibration would have been a good lead-in to the math of the Fourier transform; after all, the first Fourier transform device most people encounter is an undamped piano!

Gosper clocks as an elementary presentation of FT --- excellently done. It would be interesting to know how this material would go down at high school level.
[ I could have done without the mildly distracting background music; but at least it's not inflicted at the thunderous volume that seems to have become standard elsewhere on YouTube. ]

I'm curious as to what others think about this Fourier Transform video (1/26/2018).
