Here is a better picture of my laboratory balance. It was made by F. Sartorius in Göttingen, Germany, probably around 1910. I bought it about 40 years ago.

Exactly! And my teacher said, By the time you're older, there will be electric calculators, but it's good to know anyway.

Yes, and not only in school. My pocket-protector outfitted (he'd even wear them at the beach), engineer father (3 degrees from CalTech) made each of his kids learn the slide rule. He tested us on our skills too. One of my going-off-to-college gifts was a shiny new slide rule. I started college off studying literature/illustration/philosophy .

Post Versalog slide rule is the one I used all the way thorough engineering school.

Calculators were a new thing when I was in school and still kind of pricey. We had a lot of poor kids who couldn't afford them, so the school banned them in favor of cheaper slide rules. Mine was plastic and I don't know what ever happened to it.

I'm pretty sure that the Post Versalog slide rule that we used was made of bamboo which is dimensionally stable regardless of heat or cold or humidity.

We used slide rules in electronics school in the mid 60s. We all had the same geeky slide rule holster and book bag.

Yes. High School.

Favorite scene in Apollo 13, when they showed the engineer using the slide rule to calculate angles.
