There can never be two or more equivalent electrons in an atom, for which in a strong field the values of all the quantum numbers n, k1, k2 and m are the same. If an electron is present, for which these quantum numbers (in an external field) have definite values, then this state is 'occupied.'

God made the bulk; the surface was invented by the devil.

What really matters for me is ... the more active role of the observer in quantum physics ... According to quantum physics the observer has indeed a new relation to the physical events around him in comparison with the classical observer, who is merely a spectator.

Well, our friend Dirac, too, has a religion, and its guiding principle is "God does not exist and Dirac is His prophet."

To us ... the only acceptable point of view appears to be the one that recognizes both sides of reality-the quantitative and the qualitative, the physical and the psychical-as compatible with each other, and can embrace them simultaneously ... It would be most satisfactory of all if physis and psyche (i.e., matter and mind) could be seen as complementary aspects of the same reality.

It is not only not right, it is not even wrong.

This isn't right. This isn't even wrong.
