From the Radiolab podcast: Love 'em or hate 'em, you rely on numbers every day. We ask how they confuse us, connect us and even reveal secrets about us.

First aired back in 2009, this episode is all about one thing, or rather a collection of things: Numbers. Where do they come from, and what do they really do for us?
