Well I guess I was speaking as a phenomenologist, so I personally don't find models that describe the same physics in a new way that interesting unless such models turn out to describe some new physics. I didn't mean to dismiss those researching alternative interpretations, but the point I'm...

Actually your plain old e(-iS) gives only diagrams without endpoints; i.e. if you were to associate particles with these diagrams, you would see nothing turning into something back into nothing. These are typically called vacuum bubbles, and their sum represents the vacuum(or ground state)...

He is equating the exponents on 4.55, and using what he discusses in 4.49

Quantum mechanics is completely consistent with regular Newtonian physics, except in experimental cases where quantum mechanics dominates(usually cases of small length scales). We understand physics almost perfectly at most of the energy scales of the universe. However, at high energies, our...

Hi maverick, From what I understand, different philosophical interpretations of quantum mechanics are just different ways of talking about the same physics. For example, you might have learned about the Schrödinger picture; operators time independent, states changing in time, and the...
