Went to hear Doug present on how to use a slide rule at HackPgh last night. 20120121-084355.jpg

I found out how to use the scales for finding squares, square roots, cubes and cubed roots. I also learned that with the bigger slide rules there is no end of exponentiation.

I’m most interested in slide rules with elliptical functions. Pictured is a specialty slide rule for doing duct work.
