Had I been present at the creation, I would have given some useful hints for the better ordering of the universe

               Alphonso X, the learned King of Spain, 1252-1284

The average physicist can perhaps be forgiven a certain amount of paranoia regarding the physical universe, for it often seems that no sooner does he display his latest Theory than the universe is found to feature an additional Effect that renders said theory incomplete if he is lucky (e.g., Erwin Schroedinger) or incorrect if he is not (e.g., Niels Bohr). This element of mistery is one of the things that makes physics exciting.
