What is a Slide Rule?



Do you know what a slide rule is?

If you don't have the answer and would like to know it, please read Chun See's post on Yesterday.sg: Slide Rule.

I was quite fascinated when Chun See gave a demonstration of how to use a slide rule when I was at his place for the recent Friends of yesterday.sg (FOYer) gathering. Cool and ingenious item.
