Slide rules Rule on e-Bay (or did a couple years back when I looked). Pity I gave away my K&E Log Log Decitrig a while back. Besides - most calcs. are about a few-% estimate. Lots to be said for the discipline needed with a slide rule: ya gotta carry the decade multiplier in head. This forces a reasonable assessment of the order of magnitude you expect. The ez 10 digits of now throw-away calculators.. often gets you a quite precise number... off by 10\ufffd you forgot in some unit.
