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.

The sensation of colour cannot be accounted for by the physicist's objective picture of light-waves.

The material world has only been constructed at the price of taking the self, that is, mind, out of it, removing it; mind is not part of it...

The verbal interpretation, on the other hand, i.e. the metaphysics of quantum physics, is on far less solid ground. In fact, in more than forty years physicists have not been able to provide a clear metaphysical model.

Consciousness cannot be accounted for in physical terms. For consciousness is absolutely fundamental. It cannot be accounted for in terms of anything else.

Science cannot tell us a word about why music delights us, of why and how an old song can move us to tears.

I insist upon the view that 'all is waves'.
