What makes the general theory of relativity so important is not that it can predict planetary motions a shade more accurately than Newton’s theory can, but that it reveals and explains previously unsuspected aspects of reality,

The modern physicist, while he still believes that matter is in some sense atomic, does not believe in empty space. Where there is not matter, there is still something, notably light-waves. Matter no longer has the lofty status that it acquired in philosophy through the arguments of Parmenides. It is not unchanging substance, but merely a way of

Physics basically says we’ll understand the universe because we’re going to extremize a function. That’s what physics does—optimization, some least-action principles. So, we’re going to minimize the time, we’ll minimize the energy, we’ll minimize the distance. We’re looking for those functions that we’re trying to extremize and we’re going to
