Hi Tejinder.
Bell carefully made no assumptions of his own but was testing QM's assumptions "..will use freely all the usual notions". Much of what he said is ignored by most in QM! In his own view he falsified those assumptions. "in our opinion lead inescapably to the conclusion that quantum mechanics is at the best, incomplete." He just couldn't find which one and how.
Basically I add the 'particle morphology' which QM didn't. The simplest one possible; a spinning sphere, and find by looking harder that it produces Maxwells two orthogonal coupling forces, one linear, one 'curl', both bidirectional.
Electrons, or rather 'Fermions', rotate with detector fields, all findings and values are 'relative' between the arriving and field particles (even Bohr said the detector is part of the 'system'!).
Because fermions re-emit at c in their own centre of mass rest frame physics is localised, exactly as Einsteins 1952 conception which I've discussed, and SR and QM are unified. It's that simple (plus a couple of other consequential matters identified which all melts away the great belt of interpretive 'junk' and nonsense.
I get lots of people looking, then looking up my profile, finding I'm not an emeritous professor so dismissing it. (My essay also identifies why).
Bell brilliantly anticipated all this. All quotes from 'Speakable...'; (page numbers available if anyone wants);
"It may be that a real synthesis of quantum and relativity theories requires not just technical developments but radical conceptual renewal."
"The founding fathers of quantum theory decided even that no concepts could possibly be found which could emit direct description of the quantum world. So the theory which they established aimed only to describe systematically the response of the apparatus."
"...in my opinion the founding fathers were in fact wrong on this point. The quantum phenomena do not exclude a uniform description of micro and macro worlds...systems and apparatus."
"I think that conventional formulations of quantum theory, and of quantum field theory in particular, are unprofessionally vague and ambiguous. Professional theoretical physicists ought to be able to do better."
"What is essential is to be able to define the position of things, including the positions of instrument pointers... In making precise the notion of position of things the energy density comes immediately to mind." (but) We would have to devise a new way of specifying a joint probability distribution. We fall back then on a second choice - fermion number density."
"...the new way of seeing things will involve an imaginative leap that will astonish us. In any case it seems that the quantum mechanical description will be superseded."
"...the 'Problem of Interpretation of QM' has been encircled. And the solution, invisible from the front, may be seen from the back.."
I just went and looked round the back. But it DOES need that "imaginativ quantum leap!" to first see.
