The statement "a picture is worth a thousand words" has haunted writers for ages. It gives photographers a leg up on their counterparts, since photographers only have to find the right angle and lighting to convey what could take even the most skilled writer a couple of pages to convey.

I just finished listening to an audio presentation from Dan Pink, author of A Whole New Mind. At the end of the presentation, one statement stood out in my mind as a great take home message. "While a picture might be worth a thousand words, a metaphor is worth a thousand pictures."

My challenge- to find great metaphors in science!
