Interesting and informative. But 8 minutes too long - the woman should talk faster.

I recall seeing a mechanical machine (no electrical parts) in the Science Museum in London. There was a place to hold a sheet of paper with a printed graph of a waveform. There was a sort of stylus (linked to levers) that you would use to trace over the waveform and the machine would draw (on other pieces of paper) the first 3 (I think) harmonics of the waveform. Mechanical Fourier analysis.

Two or three hours spent thinking and reading documentation solves most programming problems.

Chem majors had lsd. Same thing.
What, I need to say something else too?
