Like.
I have no idea what you mean by this. A system of particles in an entangled state is described by a single state that cannot be... -
bhobba replied to the thread Graduate Consistent histories -- particle positions prior to measurement.I think QFT sheds light on this. The system is a disturbance in a quantum field or fields; there are no paths or positions (they are...

bhobba replied to the thread Graduate Consistent histories -- particle positions prior to measurement.I have posted this many times, but I will do it again: Basically, decoherent histories (also called consistent histories) is many...

Well, you can tell a story where the system has ... You can also tell another story, consistent with itself and measurement results, but...

The path is a possible consistent story. But it is not the only possible story. In this sense, it is not physically real. But it is more...

Love.
The formalism offers a way to have coarse grained descriptions and their compatible refinements. You are supposed to use those coarse... -

yea I’m having a tough time trying to comprehend what the formalism is saying. Are the coarse grained descriptions supposed to be the...

Are you aware that CH also has a formalism? Is your tough time related to that formalism? Or more to boiling down CH to „some essence“...

At least CH does not reject this statement, if you limit the meaning of „trajectory“ to suitably coarse grained descriptions.

One of my favorite scientific twists: Satellites designed to catch nuclear detonations accidentally discovered gamma-ray bursts — the...

I joined this forum soon after writing this paper, so this is how I have chosen my name. :smile:

OK, I guess I know how your mistake happened. At the end of the The Information Philosopher page for John von Neumann, Bob Doyle had...
