Two thoughts from Steven Strogatz:
“To grasp how different a million is from a billion, think about it like this: A million seconds is a little under two weeks; a billion seconds is about thirty-two years.”
“...nothing cements a friendship like hating the same person.”
i love that million/billion factoid. also, it seems (from googling) that a TRILLION seconds is more than thirty-one THOUSAND years. i'm going to think about that every million seconds or so, i bet.
