Brian Beckman(a astrophysicist and software architect -- a rare hybrid) and Erik Meijer(of Haskell fame) try to represent the same relationships in different notational system; one in physics and the other in programming(actually functional programming). Quite interesting and I wonder how it would go with J notation. ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
