Undergrad Bell's theorem and measurements not done
A minor note : I do not actually get the metaphor in note 5 above . What is actually the common factor? I would expect that you get higher correlations due to for example having a common taste.- Ben vdP

Undergrad Bell's theorem and measurements not done
A minor note: Unfortunately the article in Phys. Rev. Lett. mentioned in note 7 was not accessible through the link as it required credentials. There are several other links available like https://faculty.washington.edu/afine/PRL1982.pdf I do not know what would be the most proper one,- Ben vdP

Undergrad Bell's theorem and measurements not done
The previously provided feedback and references have been helpful and gave some directions to look further into. It was a bit confusing to read about measurements A0, A1, B0, B1 without an explicit statement on what they actually stand for or what relationships exists between them. It makes a...- Ben vdP

High School Chandrasekhar mass is a function of electron fraction and core entropy?
I should add that roughly at the Chandrasekhar limit the speed of the electrons are already very close to the speed of light. So impulse p is about mc and energy is now about pc according to special relativity.- Ben vdP

High School Chandrasekhar mass is a function of electron fraction and core entropy?
This could be at least a partial answer. Degenerate stars can only exist up to a maximal mass, the Chandrasekhar mass. There needs to be an equilibrium between the gravitational pull and outward pressure. For very dense stars, like white dwarfs, gas pressure and it's kinetic energy doesn't...- Ben vdP

High School Why simplifying this function generates different outputs for same input?
As already mentioned in other posts the first function is not defined for the value 2. So they aren't entirely the same functions. But if you substitute values closer and closer to 2 then the result becomes closer and closer to 4. This is a limit. Maybe that wasn't in math classes so far...- Ben vdP

Undergrad Bell's theorem and measurements not done
Indeed, one other assumption that may have been made is that the dynamic behaviour and nature of interactions should be similar to those of a large classical object. Spot the 10 differences. I think this one has been answered.- Ben vdP

Undergrad Bell's theorem and measurements not done
Indeed for large objects, but that is no longer the context. There has been another assumption made. The assumption that the measurement equals to or shows the value for the particle or is a projection of it. That is too simple, it doesn't have to be like that, and a measurement is not a...- Ben vdP

Undergrad Bell's theorem and measurements not done
Ok, thanks for the reply. I may have unconsciously rejected the realism assumption since I find it highly questionable that you can assign values to unmeasured quantities. Nor that measurements A0 and A1 are independent is just a case of coin flipping. There is a reason you can perform only...- Ben vdP

Undergrad Bell's theorem and measurements not done
I wanted to have a quick check on how Bell's theorem was formulated so consulted the wiki page: https://en.wikipedia.org/wiki/Bell%27s_theorem But then saw the following odd section: ===== Hypothetical characters Alice and Bob stand in widely separated locations. Their colleague Victor...- Ben vdP

How do entangled particles know what the other is doing?
The most entangled might (in general) be the problem description. Maybe in first order: Step 1, suppose there is a process in which two quantum particles are created that move away in opposite directions with opposite spins due to conservation laws. Here we are talking about two specific...- Ben vdP

Graduate Quantum interpretations and indistinguishable elementary particles
The issue has become more clearer now and I think these posts misses the point. It is not about individual elementary particles at all. Suppose you are writing down a description for the state of a free particle fp with schrodinger equation and wave function ... After stating that it describes...- Ben vdP

I can agree with that. p.s. Post 8 was not really relevant at all, but lets leave that- Ben vdP

Graduate Quantum interpretations and indistinguishable elementary particles
It is not just a choice. By describing it as an individual physical system, it is being overlooked that every such physical system is like any other such physical system.- Ben vdP
