Thats properly called a slide rule. I still have one, a K&E
log-log-deci-trig that still works just fine. Does that make me a
little jurassic, and probably old enough to be your grandfather? Yup.
I *made* my first slide rule out of a manila folder, following
directions in a book called "The Fun of Mathematics" (IIRC).
That was a good book. I never made a slide rule but I still have a
couple somewhere. Hemmi bamboo slide rules were the best. Come to
that, I have a couple of lovely sorobans too, but I don't use them very
Another old fogie...
Mine is a Pickett log-log slide rule and I used to carry it aound in its
case hanging from my belt like a sword before I replaced it with an HP
25 RPN programmable calculator that cost $195. It had 8 memories, 49
program steps and a 4 number stack. The calculator is long since dead,
but I still have the slide rule. I also still have the applications
manual for the calculator and I wrote an interpreter for the HP 25
language in C for a class when I went back to school for a second degree
-- in CS. I guess I'm Jurassic, too -- and a geek!
