The discussion centers around the concept of "observable" in quantum mechanics, exploring its definition, the equipment used for quantum measurements, and the implications of wave function collapse. The scope includes theoretical and conceptual aspects of quantum mechanics.
Participants express differing views on the nature of wave function collapse, indicating that multiple competing interpretations exist. There is no consensus on the specifics of observables or the measurement process.
The discussion highlights the dependence on interpretations of quantum mechanics and the potential ambiguity in defining observables and measurement processes.
Whether wave function collapse happens at all is an open question (different interpretations of quantum mechanics say different things on this topic).dsaun777 said:How small of a region of space does the wave function "collapse" into when measuring particles?
One example of equipment is photodetectors. But there are other types of equipment used, depending on what is studied. Examples of additional equipment: magnets, polarizers, waveplates etc.dsaun777 said:What types of equipment do physicists use to make all these quantum measurements that are used in books so frequently?
