Would have been nice to have seen this back in school days, hmmm, they didn't have monitors back then :(

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.

Here's a molecular machine animation - Jordan Peterson shows you a video of DNA fixing itself (https://www.youtube.com/watch?v=fkjwL6gnvoA&t=193s)
