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.
Steven Weinberg

Though aware that there is nothing in the universe that suggests any purpose for humanity, one way that we can find a purpose is to study the universe by the methods of science, without consoling ourselves with fairy tales about its future, or about our own.
Steven Weinberg
Image
If history is any guide at all, it seems to me to suggest that there is a final theory. In this century we have seen a convergence of the arrows of explanation, like the convergence of meridians toward the North Pole.
Steven Weinberg

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.
Steven Weinberg

A theorist today is hardly considered respectable if he or she has not introduced at least one new particle for which there is no experimental evidence.
Steven Weinberg

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

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

It does not help that some politicians and journalists assume the public is interested only in those aspects of science that promise immediate practical applications to technology or medicine.

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

They felt that science would be corrosive to religious belief and they were worried about it. Damn it, I think they were right. It is corrosive to religious belief and it's a good thing.
Steven Weinberg
Image
For good people to do evil things, it takes religion.

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

The invisible and the non-existent look very much alike.

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

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.

The effort to understand the universe is one of the very few things that lifts human life a little above the level of farce, and gives it some of the grace of tragedy.

If you have bought one of those T-shirts with Maxwell's equations on the front, you may have to worry about its going out of style, but not about its becoming false. We will go on teaching Maxwellian electrodynamics as long as there are scientists.

Sometimes nature seems more beautiful than strictly necessary.
Steven Weinberg
Image
It appears that anything you say about the way that theory and experiment may interact is likely to be correct, and anything you say about the way that theory and experiment must interact is likely to be wrong.

Our mistake is not that we take our theories too seriously, but that we do not take them seriously enough.
