Slide Rules

[This post disappeared from the SDF bboard for some reason, so I'm posting it here]

When I was in high school (80's) TI handheld calculators were just starting to be used regularly in math and science classes. But I had a soft-spot for slide rules, as my grandfather taught me to use one when I was 11. He was a civil engineer, and still used them regularly. When I was a bit older he gave me his prized possession, a post-versalog with the bamboo slides and instruction manual (back when instruction manuals were actually hardcover, cloth-bound books). The quality was amazing. Apparently, the more you use the bamboo slides, the smoother the action gets, a property of the natural oils in the bamboo.

I still have that instruction manual, although the original slide rule was lost in a fire. A couple of years ago, I got nostalgic and bought an identical model on ebay for about $20. They are fun to use, if not practical nowadays, and do teach logarithmic principles in a nice, visual way.
