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

I enjoy being at a meeting that doesn't start with an invocation!

It seems that scientists are often attracted to beautiful theories in the way that insects are attracted to flowers — not by logical deduction, but by something like a sense of smell.

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.

In complexity, it is only simplicity that can be interesting.

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

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