The US Navy's old training materials are fantastic for learning about various technologies.
I think their masterpiece is "Basic Hand Tools" a handbook written in plain English that describes the use of practically every hand tool ever invented.
"Basic Hand Tools" on the hammer:
>Whoever conceived the idea of cracking a nut with a rock unknowingly invented a tool. When a later genius tied a stick to the rock, he invented the first hammer. There have been a lot of improvements since that humble beginning.
The modern version "Tools and Their Uses" also covers machine tools but is less fun.
- smlavine 2y agoDo you happen to have a link to the "Basic Hand Tools" version?
- _kb 2y agoNEETS is another to add to the list. A quite literal full stack guide to electronics from the basis of matter up.
- bloopernova 2y ago"Navy Electricity and Electronics Training Series"
- copperx 2y agoI found the "textbook", but is there a video series associated with it?
- mdorazio 2y agoNot just military training videos, older ones in general are often superior to what gets made today. My favorite is probably this one on vehicle differentials: https://m.youtube.com/watch?v=yYAw79386WI https://m.youtube.com/watch?v=yYAw79386WI
- ethbr1 2y agoPeriscope Films uploads a lot of public domain US government material, and has it decently organized. The asbestos series is also interesting, hindsight being 20-20. See https://m.youtube.com/@PeriscopeFilm/playlists https://m.youtube.com/@PeriscopeFilm/playlists
- _trampeltier 2y agoI like this even more. AT&T Archives: Similiarities of Wave Behavior https://m.youtube.com/watch?v=DovunOxlY1k&pp=ygUOYmVsbCBsYWJzIHdhdmU%3D https://m.youtube.com/watch?v=DovunOxlY1k&pp=ygUOYmVsbCBsYWJ...
- halfnormalform 2y agoJam Handy films were amazing. You could show this to an audience who was morally opposed to learning about differentials and they’d still learn about differentials.
- mrandish 2y agoI've never been a car guy. While I've heard of differentials, I never understood what it was. Thanks to you posting this video, I now understand what a differential does and how it does it. (I found playing it at 120% speed to be a good balance between comprehension and engagement)
- limit499karma 2y agoI just downloaded (thanks to other commenter below) and would question the "use" part. What is the "peen" end used for? Having read the section on hammers I still don't know. (Just re-skimmed the section and I still don't know.)
- dcminter 2y agoHitting things ;) https://en.m.wikipedia.org/wiki/Peening https://en.m.wikipedia.org/wiki/Peening I dimly recall making an ashtray (hmmm, not sure that would fly these days) in high school metalwork class by beating out a piece of copper sheet with the peen until it was suitably concave.

- zerohm 2y agoI will never pass up an opportunity to use this joke: Everything is a hammer, unless it's a screwdriver. Then, it's a chisel.
- dmichulke 2y agoNot a joke and different domain, but similar structure and also noteworthy: Everyone should meditate 2 minutes a day, unless he's busy. Then he should meditate 20.
- pmcf 2y ago"The Navy is a master plan designed by geniuses for execution by idiots." - Herman Wouk, The Caine Mutiny This is completely true. 18-20-year-old kids launch and arrest aircraft on a carrier while simultaneously performing an underway replenishment, and it's just another day.
