I'm not sure what your reference is to. So wavefunction is total information about a system. Is information then a mathematical construct or a physical reality? — Mark Nyquist
Information is interaction. — Pop
"The wavefunction is the total information about a system,"
Almost correct. The wavefunction contains only information about the chances where to find a particle. Or the chances of finding a momentum in a certain range. The total information about a system is dependent on the configuration of the particles wrt to each other. But if there is no interaction with the systems surroundings, this wavefunction wavers out in phasespace (well, the position part wavers out while the momentum part collapses). After a while all useful information will be lost. The chances are conserved though (unitarity). Information about these chances, or better, the particles with their chances are conserved whenn falling into a black hole. — Prishon
That observation is an interaction. — Pop
Almost correct. The wavefunction contains only information about the chances where to find a particle. — Prishon
Only the position operator can be used to find expectation values of the wavefunction." Which is, of course, total rubbish. — Kenosha Kid
The wavefunction is our best representation of the information about a system — Kenosha Kid
Where did I state that? The momentum operator can too. — Prishon
The wavefunction contains only information about the chances where to find a particle. — Prishon
I do QM in phasespace. — Prishon
Do you really mean phase space rather than reciprocal space? Then you're doing it wrong. Or, more likely, lying about doing it at all. — Kenosha Kid

I guess we would have to say your imagination is a physical interaction neurally? — Pop
Why are you not the one lying? — Prishon
Because I'm the one who knows that you can get more than positions out of a wavefunction maybe? — Kenosha Kid
Which suggests I've at least seen the time-independent Schrödinger equation. — Kenosha Kid
As Thompson’s recent reappraisal of Husserl indicates, it was never phenomenology that trafficked in Cartesianism and representationalism, it was the early Anglo-American interpreters of Husserl who imposed their own bias on phenomenology. — Joshs
No philosopher of the past has affected the sense of phenomenology as decisively as René Descartes, France’s greatest thinker. Phenomenology must honor him as its genuine patriarch. It must be said explicitly that the study of Descartes’ Meditations has influenced directly the formation of the developing phenomenology and given it its present form, to such an extent that phenomenology might almost be called a new, a twentieth century, Cartesianism.

Where did I state you cant get more than position from the wavefunction? — Prishon
The wavefunction contains only information about the chances where to find a particle. — Prishon
Calling the Wigner function a fiekd I find very strange. QFT is not what we discuss now. — Prishon
Get involved in philosophical discussions about knowledge, truth, language, consciousness, science, politics, religion, logic and mathematics, art, history, and lots more. No ads, no clutter, and very little agreement — just fascinating conversations.
