I don't like it, and I'm sorry I ever had anything to do with it.

In this communication I wish first to show in the simplest case of the hydrogen atom (nonrelativistic and undistorted) that the usual rates for quantization can be replaced by another requirement, in which mention of "whole numbers" no longer occurs. Instead the integers occur in the same natural way as the integers specifying the number of nodes in a vibrating string. The new conception can be generalized, and I believe it touches the deepest meaning of the quantum rules.

An animal that embarks on forming states without greatly restricting egoism will perish.

Matter and energy seem granular in structure, and so does “life”, but not so mind.

The great revelation of the quantum theory was that features of discreteness were discovered in the Book of Nature, in a context in which anything other than continuity seemed to be absurd according to the views held until then.

The task is not to see what has never been seen before, but to think what has never been thought before about what you see everyday.
