It always amazes me when I think about the Apollo series of trips to the moon. Especially that the astronauts took slide rules with them...grin When Chuck showed me his new acquisition while he was home, once again I had to wonder why we always seem to think that prior to computers everyone had to work everything out in their head or on a piece of paper... This is a 1920's desktop calculator... he has a small one that can be carried around in a pocket...
