My advice is to go for the messes - that's where the action is.

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.

It is positively spooky how the physicist finds the mathematician has been there before him or her.

Elementary particles are terribly boring, which is one reason why we're so interested in them.

Maybe nature is fundamentally ugly, chaotic and complicated. But if it's like that, then I want out.

It is even harder to realize that this present universe has evolved from an unspeakably unfamiliar early condition, and faces a future extinction of endless cold or intolerable heat. The more the universe seems comprehensible, the more it seems pointless.

As for me, I have just enough confidence about the multiverse to bet the lives of both Andrei Linde and Martin Rees’s dog.
