Good Lord, the connections around here! Lobachevsky (the song, not the man) doesn't teach any math, except that it was about the 3rd year of college before than I learned that "an analytic and algebraic equation of locally Euclidian metri(ci)zation of internally differential Riemannian manifold " actually made sense (and that the Bojemoi! exclamation on the end meant "Ohmygod" in Russian) I second the post about Schoolhouse Rock. The trouble with setting times table to music is that all the times tables are arbitrary; you could substitute one number for another and it would make just as much poetic and metric sense. (there is a song from Mewfoundland containing sailing directions which is just as arbitrary) but the really good songs are the ones in which the next line is almost pre-determined by what has come before. Not making much sense, but clear in his own mind (if I still have it) is PETE
