on a tangent here - same with my calculus teacher. He would go on and on for forever about the room we were in - it was a chemistry lab: (he was a short guy) the small cabinet in front of the chalkboard only allowed him to use the bottom half of the board. The board was never erased before he got there. The erasers were never cleaned and were so full of chalk they wouldn't erase and made too much dust in the air. The sound echoed. Then he finally got around to the lesson. He put the equation on the board, spent 15 minutes showing us how to do the algebra (that we already knew) to set up the calculus portion, then he says: "Then you do the calculus and the answer is...". I never learned a thing from that guy but somehow got a passing grade.
