“Theoretical physicists live in a classical world, looking out into a quantum-mechanical world. The latter we describe only subjectively, in terms of procedures and results in our classical domain.” WorldTermResultsLatterQuantumPhysicistDomainTheoreticalProcedures Author:John Stewart Bell
“The concept of 'measurement' becomes so fuzzy on reflection that it is quite surprising to have it appearing in physical theory at the most fundamental level ... does not any analysis of measurement require concepts more fundamental than measurement? And should not the fundamental theory be about these more fundamental concepts?” ShouldDoeLevelsTheoryReflectionConceptsFundamentalsAnalysisSurprisingMeasurementAppearingFuzzy Author:John Stewart Bell
