"My favorite way to think of it is in terms of seconds," says David Schwartz, a children's book author whose How Much Is a Million? tries to wrap young minds around the concept. "One million seconds comes out to be about 11½ days. A billion seconds is 32 years. And a trillion seconds is 32,000 years. I like to say that I have a pretty good idea what I'll be doing a million seconds from now, no idea what I'll be doing a billion seconds from now, and an excellent idea of what I'll be doing a trillion seconds from now." A stack of one trillion $1 bills would reach more than a quarter of the way to the moon — replacing one incomprehensible thought with another doesn't do much good.
