Quantum Field Theory in a Nutshell A. Zee
Publisher: Princeton University Press

That, in a nutshell, is conservatism. Physics itself is riven by the competing frameworks of quantum theory and general relativity, whose differing descriptions of our world eerily mirror the wave-particle tension. "Principles of Quantum Mechanics" is a little better. When it comes to the very big and the extremely small, physical reality appears to be not one thing, but two. By AddToAny · General Stupidity. 23: Physically, D(x) [propagator] describes the amplitude for a disturbance in the field to propagate from the origin to x.

Chapter 1 of Srednicki's QFT text has a great exposition of exactly what you ask for and this particular chapter is not advanced mathematically for an undergraduate (at least in principle), in my opinion anyways. If you're more comfortable with relativity/field theory than with quantum mechanics, then maybe check out Zee's "Quantum Field Theory in a Nutshell". In trying to resolve the stubborn dualities of their field, physicists create ever more mind-boggling versions of reality. Zee, Quantum Field Theory in a Nutshell, p.

Remains the most plausible institutional vehicle for conservative ideas about health care…” the asshole remains the most plausible corporeal vehicle for smelly gasses.
