How a Watch Works (1949) [video]
- tzs 11y agoI've never understood why these old instructional films so often seem much better at getting things across and making them stick in my mind than more modern material. A couple other examples. 1. A 1959 film from Bell Labs on wave behavior that made standing wave, reflections, energy loss due to impedance mismatch, and impedance matching much clearer than anything else I've seen: [1]. 2. A 1937 explanation of how the differential in a car works: [2]. Here is another upload of that which is lower resolution, but has more from the same source in the sidebar [3]. I suppose it could be something akin to survivorship bias that makes old educational films seem so good--the bad ones don't get remembered 60 years later.

- Animats 11y agoThis is spam. Someone copied an out of copyright industrial film from the Internet Archive and "monetized" it on YouTube.[1] The Internet Archive has a good selection of other Jam Handy films. Recommended: "American Maker" and "Master Hands". There's also a long series of Chevrolet-sponsored films on brakes, suspensions, differentials, engines, and such.
