A spontaneous and lengthy chat about teaching states of matter, about glasses and supercooled liquids and the Challenger Space Shuttle disaster. Also, back to school and the double life of a teacher flipping from summer and back into the groove. And Ed's hilarious umbrella joke, plus Toby remembering the blandness of Tracy Chapman songs live on air. Next week: more meandering and a preview of the Rethinking Education conference.
