... These calculations are not only simpler, because the commutators were used only for the equations of motion 共2.2兲, but easier for students because the calculations closely follow the corresponding classical calculations. Next consider how the spread of the position and momentum change with time for ...

The new Hamiltonian is superior to the original one in essentially three ways: it involves the experimental electron mass, rather than the unobservable mechanical mass; an electron now interacts with the radiation field only in the presence of an external field, that is, only an accelerated electron ...

... electrons. By conservation of angular momentum, the sum of the two electrons angular momentum must also be 0. If we measure the z-spin of one electron to be +½ then we know that the other electron must have a z-spin of –½. But before we measure the first electron, it is in a mixture of +½ and –½ spi ...
