You may object that by speaking of simplicity and beauty I am introducing aesthetic criteria of truth, and I frankly admit that I am strongly attracted by the simplicity and beauty of mathematical schemes which nature presents us. You must have felt this too: the almost frightening simplicity and wholeness of the relationship, which nature suddenly spreads out before us.

Natural science, does not simply describe and explain nature; it is part of the interplay between nature and ourselves

Every tool carries with it the spirit by which it has been created.

The structure underlying the phenomena is not given by material objects like the atoms of Democritus but by the form that determines the material objects. The Ideas are more fundamental than the objects.

I think that the discovery of antimatter was perhaps the biggest jump of all the big jumps in physics in our century.

Only a few know, how much one must know to know how little one knows.

The problems of language here are really serious. We wish to speak in some way about the structure of the atoms. But we cannot speak about atoms in ordinary language.
