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.

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...

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...

I might have lost some of the formatting when trying to copy and paste from the wiki page.

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...

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...

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...

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

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.

Because elementary particles are identical. The indistinguishability is a consequence of that. A photon may have a different energy, but still a photon is like any other photon. It starts to look now that by interpreting a physical system as an ensemble the concept of identical particles got...

It is not about describing a single elementary particle, but about an individual physical system. Let me guess, you never had a real look at the link provided at the beginning. There can be different views and opinions about it, but included is a discussion about what an individual physical...

No, there is no such requirement indeed. Thus you are trying to describe with a wave function a system and interpretate it as an "individual physical system" (and not an ensemble) based upon underlying elementary particles that in principle don't have such individuality. I got the impression...

You have corrected me and rightfully so for not taking sufficient time for it. It is very difficult to express these things. Elementary particles simply don't have any individuality. You can distinguish them if they are spatial apart etc.. If in an interpretation it is posed that you are...

OK, during the weekend I had some time to think it over. The electrons cannot be labeled if they each have a probability for presence at a certain position in such a system. That can be illustrated as follows. If it would have been possible to make a measurement at the location and finding an...

Yes, I understand that. You cannot label them if the different electrons have a probability to be in the same position in such a quantum system. By the way "shut up and calculate" is actually interpretation dependant. According to Ballentine that statement is superfluous. So is the idea that...
