Humans invented time by measuring how many times a certain atom vibrates in a certain amount of time.
Yo dawg, I herd you like time.
I'm guessing that the usages of time refer to two different notions? It's all starting to get a little Inception to me.
D'oh. I posted the bold part in a hurry - obviously it is a circular reference.
"Humans invented time by taking a number of vibrations from a certain atom and calling that one second." would have been a better thing to say.
