Symmetries and quantum field theory: an introduction Jean-No¨ el Fuchs
... Symmetries constrain the form of theories (symmetry dictates design). We shall use space-time symmetries to construct relativistic field theories. Symmetries imply conservation laws. Even more so in quantum physics. In addition to space-time symmetries, there are also less obvious internal symmetrie ...

... • Probabilistic nature of QM is in extracting info from the WF; • Physical quantities are represented by linear operators. Their eigenvalues provide the allowed values for those quantities; • Measurement sensitivity is reflected in the action of those operators. In particular, the commutator of two ...
