Time in quantum mechanics
... much attention has been given to finding an analogue of the uncertainty relation (0.2) in the case of energy and time. If time is not an operator, a relation of this type cannot exist. Nevertheless there do exist ‘uncertainty’ relations between energy and time of a different kind, for example the re ...

... A popular class of problems specifies a force and asks about the motion, or vice versa. These problems look like physics, but they are exercises in differential equations and geometry, thinly disguised. To make contact with physical reality, we have to make assertions about the forces that actually ...

PHYS 415 Introduction to Nuclear and Particle Physics
... Electromagnetic and weak decays violate some of the quantum numbers, i.e. those related to the quark flavor. Weak decays may be divided into: Hadronic: Only hadrons in the final state. Semi-leptonic: Some lepton(s) in the final state. Leptonic: Only leptons in the final state. ...

This may have been fixed (or rather, side-stepped) as of January 2015 ...
