    A Bell inequalities demonstration

    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 ...

    I Does information get lost by measurement?

    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 Patrick

    I What Is the Role of Ontology in the Interpretations of Quantum Mechanics?

    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 On the relation between physics and philosophy

    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...

    I What Is the Role of Ontology in the Interpretations of Quantum Mechanics?

    Does conscious experience derives from a material basis ? Correlation isn't causality. Patrick

    I On the relation between physics and philosophy

    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 ? Patrick

    I On the relation between physics and philosophy

    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...

    I Does a measurement setup determine the reality of spin measurement outcomes?

    Can an entity that is not measurable be considered as being ontological? /Patrick

    I Does a measurement setup determine the reality of spin measurement outcomes?

    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...

    I Does a measurement setup determine the reality of spin measurement outcomes?

    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...

    I Polarization in Bohmian mechanics

    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...

    A Bohmian mechanics for instrumentalists and quantum measurement

    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. /Patrick

    A Bohmian mechanics for instrumentalists and quantum measurement

    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

    A Bohmian mechanics for instrumentalists and quantum measurement

    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...
