Hi Manuel,
I liked your essay very much. I do have a couple of questions, however. On page 3, in discussing the two-slit experiment, you talk about a "deterministic selection" being applied, which leads to the observation of a collapsed state, or eigenstate. Now, it's the presence of a detection screen behind the slits that makes such observation possible; so, it seems that the "selection" here is associated with the screen. But I'm not sure why you describe this selection as deterministic; for unless you make some additional assumptions, the effect of the screen on the relevant observed eigenstate appears to be only probabilistic, just like the effect of dropping a coin on the edge of a cup.
The second question concerns p. 6, in the discussion of Figs. 4a and 5a. If I understand correctly, you're identifying a spin-down orientation (-) with the non-existence of a selection event; but what is the rationale for this identification? Your remarks near the bottom of p. 5, in particular, seem to imply that a state doesn't exist if there's no selection associated with it; but in that case, it follows that spin-down states don't exist, which doesn't make sense (or, is blatantly false)- hence, equating spin-down with no-selection seems highly problematic.
I apologize if I've misunderstood your ideas, and I'd be grateful for any clarification.
Best of luck,
Willard
