Nonlocal interactions: a jammerian analysis

It is general practice to describe a microsystem by means of a model characterized by probability amplitudes possessed at each spacetime point between preparation and measurement events. Recent developments initiated by Bell's theorem indicate that any such model must in some cases be considered as participating in nonlocal interactions. Adapting ideas originated by Jammer, this paper asserts that that conclusion may be indicative only of limitations in the applicability of physical properties in the modelling of microsystems and thus might not lead to inferences about the microsystems in themselves. Recent discussions of the Aharanov-Bohm effect further exemplify the difference in these alternative interpretations of nonlocality.
