    Twenty-five years ago or more my late father attended a talk by the very famous early computer pioneer Grace Murry Hopper.  She handed out foot-long chunks of coaxial cable, pointing out that electromagnetic waves would traverse the cable in one nanosecond.  Ever since I've remembered "one foot equals one nanosecond"

    Would love to have one of the souvenir rulers!
