If you liked that video you'll like this one too, which explains that mechanical and electrical parallel but in the other direction.
Prof. Malcolm C. Smith had an electrical circuit and made its mechanical equivalent. His invention (the inerter) gave the F1's McLaren team an advantage in 2007.

I really enjoy this channel: https://www.youtube.com/@WristwatchRevival He takes watches that need repair, disassembles them to basic components, washes them, and then reassembles and tunes them, replacing any parts that have broken (often the mainspring).
It doesn't have the explanations or the math, but the cameras are high quality and you can really see just how jiggly the balance wheel and spring are, and how the watch will just "spring to life" when you install those bits.

I remember watching MIT lectures in OpenCourseWare back in 2007, before I started at university. What an amazing resource it was at the time.

I did the same thing, at the same time! I'm pretty self-directed when it comes to learning, so access to the raw materials of a course was great and sufficient. Never missed interactivity. I tried Coursera years later, it was much more like enrolling in a real class virtually.
But yeah, great to see OCW still going strong. It's pretty remarkable no administrator has tried to mess with it -- although I wouldn't know if they had.

they did censor (i.e. delete) physics professor walter lewin's popular physics videos because at some very advanced age he was still making known his interest in coeds (or something like that) and, rather than celebrate his robust health and appetites, they decided to unperson him.

"Robust health and apetites" is an interesting euphemism for creep.

Whatever. The world is a slightly worse place because those lectures were pulled offline... and the world is a much worse place because of the entirely-predictable overreaction to such actions.

Creep or not, the lectures were great. I hope they're at least available somewhere. Edit: ah someone put them on YouTube

Sussman is a treasure. I love how deep he goes into topics.
