Hello,
In this thesis https://tel.archives-ouvertes.fr/tel-01743877/document at "1.2.2 Bell inequalities" page 7-8 it's define a correlation function :
C(x y) = P(+ + |x y) + P(− − |x y) − P(+ − |x y) − P(− + |x y), with −1 ≤ C(x y) ≤ 1.
How do one get to this relationship −1 ≤ C(x y) ≤ 1 ...
Hi all,
Concerning the collapse of the wavefunction, Franck Laloë proposes a theoretical model : https://phys.org/news/2020-02-deconstructing-schrdinger-cat.html
The preprint : https://arxiv.org/abs/1905.12047

Mind i don't know what is it. However smell, color, taste, sound, hot/cold, pain, ... are foremost first person experiences.
It is through these sensations in the first person that we become aware of ourselves and of what surrounds us. The rest, such as for example our theories, are derived...
I don't have a problem with philosophy or metaphysics. I became aware a long time ago that we perceive the "world" first and foremost through our consciousness (our first person experiences) and that by inter subjectivity via language we create a scientific process of objectification, in the...
What is the meaning of "understanding" ?
Finding a primitive formulation of quantum physics like the set theory which is the foundation of Mathematics or finding methaphysical beliefs to replace naive realism ?

The problem seems to be primarily a problem of interpretation of the theory of quantum mechanics. Richard Feynman lamented “I think I can safely say that no one understands quantum mechanics.”.
If we adopt vanhees71's point of view, which is to see the models derived from the theory of quantum...
The action has the dimension M·L2·T-1. I don't think that the wave function has a dimension.
if the wave function is just a calculation tool for calculating measurement predictions, can it then be considered as an "ontic/beable entity"? A Platonist may answer yes, hence the ambiguity of these...
For example by analogy: We never measure absolute positions or speeds, but always distances between several objects taken as a reference frame or relative speeds.
And so it is through an interactive process that we give birth to the physical quantities position and velocity, which do not...
hi;
This paper describes the evolution of the polarization state during its propagation inside a polarizer.
The Stokes vector s determines a point located on the Poincaré sphere S2 of radius s. The direction of the vector s, characterizes the polarization. Thus, the polarization state of the...
Yes, what I wanted to raise awareness about is that what is stored in a computer is not what is physically measured. We need an interpretation/model that can be formalized by computer.

in the same way, we can notice that many outcomes are numbers, real numbers. Are numbers a physical property of "nature" that we can observe/read or rather an abstract conception imagined by us, human being?
/Patrick
Position derives from the senses by which human beings perceive "nature". We can imagine abstract observables like the spin, but at the very end, what we observe derives from our human being senses.
Another example is cloud chamber to observe particle.
That's how I understand the concept of...
