In need of a human Dictionary!!! OK - I somehow have forgotten my favorite word. I have used it for years, but for the past week it has completely slipped my mind. To all you intellectuals - please help me remember what the word is. OK - The word is used in describing a situation of perpetual motion. Because A happens, B occurs, and because B occurs A occurs. It is either a negative or positive exponential result. Thats the best description I can think of ... please tell me the word Im looking for.
