[Wick]

I forgot one thing--the fine structure constant. Feynman speaks of a number that "all good theoretical physicists put...up on their wall and worry about. That number is the fine structure constant, or in this case the coupling constant that describes "the amplitude for a real electron to emit or absorb a real photon." That number just happens to be 137.03597. Feynman prefers it in a different form (-0.08542455). Now these numbers mean almost nothing to me (given my background in languages), but I can't help thinking that this number somehow describes the relationship between 4-d particles of matter interacting with 4-d particles of light on the surface of a 3-d hyperplane. I'm sure that if such a relationship exist, all never be able to write it in mathematical terms. Right now this is just a gut feeling. Its seems a beautiful relationship, so I'll stick with it until a better idea comes along.
