Every librarian/math geek's dream

I've been reading Indexed, a delightful book of hand-drawn charts, graphs and - yes! - even Venn diagrams that "make fun of some things and sense of others". Jessica Hagy, who also blogs these gems at Indexed blog, has an amazing knack for distilling thoughts into simple images, each of which fit on a single index card.

Take today's, for example. It'll take you a minute to parse out this diagram, and then...wham!
