What the Meter Means

File this under You Learn Something New Every Day

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??
