International Slide Rule Museum

How fun. I also found this when I was looking to learn a bit about how to operate a slide rule a friend gave me:

They're really interesting items and of course can be gotten for a couple bucks at any antique knick-knack shop. It's worth taking an hour or two to learn the general idea of how they work if you're curious.

When I joined the USN in 1975 the first course I was given in Nuclear Power School was how to use a slide rule. When I told my dad this he gave me his beautiful K&N slide rule with a great hard leather case. He's gone but the slide rule sits safely on a closet shelf.

My aunt donated my grandpa‘s old slide rule there some time ago [0]. Crazy how far we came in just two generations.

Fun to see this site show up on HN :)

If you only want an approximate answer, and you have a slide rule handy (there are two big ifs), and it's a problem the slide rule is built to handle, then it's probably speed-competitive with a calculator. Maybe faster.

Not an all-purpose device, though.

Ok, let's do this
