Well, Art is busy, so life imitates a cartoon instead.

The other night on the Colbert Report, he interviewed George Johnson, author of The Ten Most Beautiful Experiments (which I’ve mentioned before), and the idea for which was stolen from Chad. The interview was standard Colbert schtick, and Johnson doesn’t really explain what’s going on with the physics, but the last 30-45 seconds is great, and becomes the XKCD cartoon “The Difference,” about science and pain.

UPDATE: if you are getting frustrated with the Comedy Central player, there’s an embedded link here that seem worked better for me. (I can’t embed the video myself, alas)
