How many know what a slide rule is, how to use one AND still own one?
Other than me.
Still have my dad’s pre-WWII with ivory scales in velvet lined wooden case.
Do you mean a couple of Log yardsticks sliding back & forth?
The Slide Rule: A Computing Device That Put A Man On The Moon
Me.
I just opened my drawer under the computer and pulled out my Keuffel & Esser Beginners Slide Rula 4058W. On top of it was a small protractor. Downstairs I have French curves and I think somewhere I may have a Leroy Lettering Set which I used to make graphs for my boss’ journal papers. I even have one or more drafting sets, not as complete is the one shown here. No I am NOT A PACKRAT! heh heh, I just want to be ready for the next Carrington Event.
