If (the antiproton) had not been discovered, the foundations of physics really would have crumbled.

[Science] is corrosive of religious belief, and it's a good thing too.

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?

Our job in physics is to see things simply, to understand a great many complicated phenomena in a unified way, in terms of a few simple principles.

I can hope that this long sad story, this progression of priests and ministers and rabbis and ulamas and imams and bonzes and bodhisattvas, will come to an end. I hope this is something to which science can contribute ... it may be the most important contribution that we can make.

For good people to do evil things, it takes religion.

In our universe we are tuned into the frequency that corresponds to physical reality. But there are an infinite number of parallel realities coexisting with us in the same room, although we cannot tune into them.
