"I met him frequently in later life, and, of all the physicists that I met, I think Schrodinger was the one that I felt to be most closely similar to myself. I found myself getting into agreement with Schrodinger more readily than with anyone else. I believe the reason for this is that Schrodinger and I both had a very strong appreciation of mathematical beauty, and this appreciation of mathematical beauty dominated all our work. It was a sort of act of faith with us that any equations which describe fundamental laws of Nature must have great mathematical beauty in them. It was like a religion with us. It was a very profitable religion to hold, and can be considered as the basis of much of our success."
