I have a thin slide rule from high school as well as a pocket-sized one. I also have a full-width slide rule with all the rules from college. Pocket calculators had just come out when I was in college and cost a lot, some models costing over $800.
I have a working slide rule as a tie clasp. No one under 60 knows what it is when I wear it.
That's tiny. Will it even do 2 times 2? :)
I'd still wear one, if I had one.
Yes, you can multiply and do square roots with it. Today, I need a magnifying glass to see it even when I'm wearing my glasses.
