Great movie, but not one of the engineers was totin' a slide rule.

 

I'd reckon the younger folks reading this are asking, "What's a slide rule?"

I always did figures in my head. Hated it in the army when I had use forms, pencils, and books of log tables.

 

Maybe slide rules didn't have the required degree of accuracy. They are not 5 digit instruments.

Haven't seen it yet. Did they have pocket protectors?

going through stuff a while back and found my slide rule. Took a few tries to get it to work - old battery a little weak would be my quess...

 

The contacts are likely corroded. That or the denominator is stuck. :)

I've got a very fine slipstick that will calculate almost anything. Had a carrying case that I used to hook to my belt. Once I got out of college (1965), never used it! By the time I got out into the aerospace industry, electronic calculators had made the sliderule obsolete! :( Showed it to a couple of high school students...and could barely remember how some of the more archane scales worked! -_- My current "sliderule" is a pocket calculator that cost about $15.

It has trig functions and statistical functions on it. There are pocket calculators today that have more memory than the main computers aboard the Apollo spacecraft and maybe even the Space Shuttles!

I used a slide rule in High School physics and in the Navy's Nuclear Power School, even though portable electronic calculaters were available. The top rule is the one I used.
