I'll recommend a couple of other channels:

- Old Royal Navy instruction manuals and documentaries: https://www.youtube.com/@davidbober7035

My favorite is Hands To Flying Stations (1975): https://youtu.be/cALccuPShQc

- Historic films and clips, mostly focused on workplace safety: https://www.youtube.com/@markdcatlin

My favorite is NASA's Toxic Propellant Hazards: https://www.youtube.com/watch?v=ND2TeNfcmKA

I'd like to throw in a recommendation for Huygens Optics: https://www.youtube.com/@HuygensOptics

Everything you ever wanted to know (and more) about light and lenses, explained in a way that's totally comprehensible if you learned electricity and magnetism physics in college.

Yes - he's one of the very best! I loved his 3 part series on making a reflector telescope from a single chunk of glass.

That toxic propellant one is fantastic.
