In 1983, the length of the meter was redefined by the international body Conférence Générale des Poids et Mesures (GCPM) by a method to give greater accuracy. Originally based on one ten-millionth of the distance from the North Pole to the equator, the meter was re-established as the distance that light travels in a vacuum in 1/299,792,458 of a second.
I had no idea that the meter was anything other than an arbitrary measurement. Opens up a whole new category of things that I could explore, but probably won't.
And Congrats/Mazel Tov to my CA friends JJ and John, who are welcoming baby #4 into their family. Is it a coincidence that his middle name is Jock??
