“A physical constant in quantum mechanics may thus be looked upon either as an observable with a single eigenvalue or as a mere number appearing in the equations, the two points of view being equivalent.”

“...How then do they manage with these incorrect equations? These equations
lead to infinities when one tries to solve them; these infinities ought not to be there.
They remove them artificially. ... Just because the results happen to be in agree-
agreement with observations does not prove that one's theory is correct. After all, the
Bohr theory [of the hydrogen atom] was correct in simple cases. It gave very good
answers, but still the Bohr theory had very wrong concepts.”
