Lacking more direct observational information, after assigning the quantum state of a system appropriate to her physical situation, an of the laboratory's quantum state to the situations of Eugene, John, respectively A true claim about the value of a physical magnitude states an objective ./cache/work_ibqdhdyxlbfhfctmepbzttunay.pdf ./txt/work_ibqdhdyxlbfhfctmepbzttunay.txt
