You just gave me a flashback of explaining a slide rule to my grandkids.

Boy does that bring up memories, Maj Kim Patterson! Having a slide rule and knowing how to use it was a big thing, back in the day!

Ya, I recall some not so nice comments about needing something so costly for a middle school kid.

Still have my *trifecta* - A TI 51A, HP (reverse logic) and a slide rule.
Competed against MIT way back in the day and never forgot their cheer/fight song!

Love the fight song. Think I still have my slide rule somewhere in garage attic, sure the white coating is completely yellow by now.
