beables represent local hidden variables that are supposed to explain correlations seen in observables, and observables are just facts we can actually measure, like whether a particle gives result "spin-up" or "spin-down" when passed through a Stern-Gerlach device oriented at some angle. Take a look at my scratch lotto card analogy in this post
(beginning with the paragraph that starts 'Suppose we have a machine that generates pairs...')--the observables would be the cherries or lemons that Alice and Bob actually see when they pick a single square to scratch, the beables would be the complete set of hidden fruits behind all three squares, which are used to explain why it is that they always find the same fruit whenever they scratch the same box (the assumption being that on each trial, the two cards have the same set of hidden fruits).
I don't know much about relativistic quantum theory which is where I think "spinors" appear--my question here would be, are spinors actually local
variables associated with a single point in spacetime, or are they defined in some more abstract "space" like Hilbert space?
Not clear what you mean by "this subset a
G conditional", can you elaborate?
What do you mean by "implicit in"? Do you mean that the measurement a and the result G can be determined from the value of lambda? If so, I'm not sure why you think that, the measurement can be random and I told you in post #82 on this thread
that the probabilities of different outcomes may be other than 0 or 1 in a probabilistic local realist theory.
Nothing "undefined" about it, as I said to billschnieder:
Like I said to billschnieder in the last post, the basic logic of Bell's argument is a proof-by-contradiction. He starts only by assuming that the universe obeys local realist laws, and then shows that they produce predictions about the statistics of Aspect-type experiments that contradict the predictions (and experimental results) of QM, and so concludes that QM is incompatible
with local realism (so if QM's predictions hold up to experimental tests, our own universe must not obey local realist laws).
