Observables and measurements
== Observables == Under the notion of observable in quantum mechanics one ... which can be measured in some experiment. Mathematically observables are postulated to be Hermitian operators mapping Hilbert ... itself and have following properties: Eigenvalues of observables are real and in fact are possible outcomes of measurements ...
