... The measurement of say Xs is done by coupling the quantum system S to another system, the probe P. In real experiments, P will have many degrees of freedom. The final result of the interaction of P with S will be a record or reading. This final stage is classical, no issue of non-commuting operators o ...

Particle Notes
... We can see right away that in the limit |~p | → 0, solutions have E = ±m. Does this mean that the Dirac Equation has negative energy solutions?! No. We interpret the “negative energy solutions” as antiparticles with positive energy. Antiparticles are like their corresponding particles with all signs ...
