God used beautiful mathematics in creating the world.

It seems that if one is working from the point of view of getting beauty in one's equations, and if one has really a sound insight, one is on a sure line of progress.

I do not see how a man can work on the frontiers of physics and write poetry at the same time. They are in opposition.

If we are honest - and scientists have to be - we must admit that religion is a jumble of false assertions, with no basis in reality.

The physicist, in his study of natural phenomena, has two methods of making progress: (1) the method of experiment and observation, and (2) the method of mathematical reasoning. The former is just the collection of selected data; the latter enables one to infer results about experiments that have not been performed. There is no logical reason why the second method should be possible at all, but one has found in practice that it does work and meets with reasonable success.

The only object of theoretical physics is to calculate results that can be compared with experiment... it is quite unnecessary that any satisfactory description of the whole course of the phenomena should be given.

There are always more people who prefer to speak than to listen.
