Quantum phenomena may have macroscopic counterparts

Abstract

From various points of view it is argued that one may find phenomena similar to the quantum effects also in macroscopic cases. This forces one to give up as a general requirement the assumption of realism as formulated by Gill and others. For any potential set of experiments on a limited set of units, we find it useful to introduce for these units the concept of a total parameter, a set of parameters which is so large that a joint value is meaningless.
