“On the side of physics, there were a few key figures in Oxford who realized, in all probability unlike the majority of their colleagues in the physics department, that physics without interpretation is only part of the story, and that theories like quantum mechanics need careful foundational reflection.”

Context: The underlying physical laws necessary for the mathematical theory of a large part of physics and the whole of chemistry are thus completely known, and the difficulty is only that the exact application of these laws leads to equations much too complicated to be soluble. It therefore becomes desirable that approximate practical methods of applying quantum mechanics should be developed, which can lead to an explanation of the main features of complex atomic systems without too much computation.
