If language is to be of any use to us, then we ought to try and preserve the meaning of words, and 'god' historically has not meant the laws of nature.

Its a consequence of the experience of science. As you learn more and more about the universe, you find you can understand more and more without any reference to supernatural intervention, so you lose interest in that possibility. Most scientists I know dont care enough about religion even to call themselves atheists. And that, I think, is one of the great things about science-that it has made it possible for people not to be religious.

Nothing in physics seems so hopeful to as the idea that it is possible for a theory to have a high degree of symmetry was hidden from us in everyday life. The physicist's task is to find this deeper symmetry.

Most scientists I know don't care enough about religion even to call themselves atheists.

How strange it would be if the final theory were to be discovered in our lifetimes! The discovery of the final laws of nature will mark a discontinuity in human intellectual history, the sharpest that has occurred since the beginning of modern science in the seventeenth century. Can we now imagine what that would be like?

Journalists generally have no bias toward one cosmological theory or another, but many have a natural preference for excitement.

I now want to tell three stories about advances in twentieth-century physics. A curious fact emerges in these tales: time and again physicists have been guided by their sense of beauty not only in developing new theories but even in judging the validity of physical theories once they are developed. Simplicity is part of what I mean by beauty, but it is a simplicity of ideas, not simplicity of a mechanical sort that can be measured by counting equations or symbols.
