Friend gave me one of his old slide rules. Coincidentally it is the same make and model of my old slide rule that was stolen years ago. Sweet!
@evilscientistca The Next Generation: As a kid, maybe 7 years old in 1982, I remember playing with my dad's incredibly posh, rather expensive, TI-30 electronic calculator to replace his slide rule. Didn't know that the sin/cos/tan buttons did, but the display would flicker when you used them.
Fast forward to 2021, I'm in a new job as a school science technician in an old school, and at the back of a drawer, in a little used store, marked "beware of the leopard".
Raspberry Pi for scale...
@evilscientistca I also found a slide rule, which I bring out to show the senior physicists. I never used one on purpose, but can do a few basic things to demonstrate it. We still make a point, at curriculum level, of Vernier readings from about 15 years old though, both physics and technical/engineering.
When I was in high school, I took a slide rule instead of a calculator to physics exams. :)
Hm~ also, can one use a Vernier correction on slide rules? It seems that it was a thing: https://www.sliderulemuseum.com/Patents/US/2424713.pdf (I don't recall the nonvertical lines on any slide rules I had.)
