The math advisers from CalTech had a little fun on Friday's episode of "Numb3rs". The Mathematician and the Physicist are looking at a dead person's notebook. They're dead serious. MATHEMATICIAN: it's a category-based approach to I don't know what, but it's a forcasting system. Right?. It's very sophisticated. PHYSICIST: [In awe at what he sees] Oh, no, no. no. This is more than sophisticated. You know what this reminds me of? A topos approach to Bach's music. MATHEMATICIAN: I said: very sophisticated. FBI AGENT: Yes -- you did. Be assured that neither the page we see from the notebook nor the rest of the program had anything to do with categories, topoi or Bach.
