7 Commutators, Measurement and The Uncertainty Principle
... are inherently incompatible with each other and the measurement of one will destroy information of the other(s). Such incompatibility is encoded in mathematical language as non-commutativity of the operators associated with the observables. We then show that the Postulates of Quantum Mechanics lead ...
