Re: Quantum Physics, Robert's models, sensory perception

Wow....I miss a few days of email and I come back to alot of reading! :)

I have a general reply to most of these posts by Ionel and Howard, but I can
tell already it will be rather lengthy, so it may take a day or so. The
short response re Feynman 'sum over histories' is that I am quite certain
that is does not take us out of the state-based paradigm. It is only yet
another way to encode quantum states and trajectories information. See, for
example:
