Changes

The first sentence, that Field Theory is a generalization of QM to infinite degrees of freedom, is true, but vague to the ordinary reader.  In my edit, I changed that to emphasize what infinite degrees of freedom we're talking about: namely, unlimited numbers of particles with any arbitrary energies/momenta, and the possibility of CHANGING the number of particles.

The previous line that said field theory is "sometimes called quantum electrodynamics" was just wrong. QED is a SUBSET of field theory. Other parts of field theory include QCD, electroweak theory, and on and on. So saying that field theory is sometimes called QED, is like saying algebra is sometimes called the quadratic equation. -- [[User:Cuddlytakun|Cuddlytakun]] 13:10, 2 June 2009 (EDT)
