The Slide Rule: Calculating by Mind and Hand (2005) [pdf]
- bediger4000 2y agoThe slide rule museum site, and slide rule related content, show up on HN regularly. How many HN participants have a slide rule? I got one in 1975 or 76, because a 4 function calculator my mom got me couldn't do some, cosine, etc. I believe slide rules were on a fire sale basis at the local college, because of calculators coming on the market.
