One of the major ingredients for professional success in science is luck. Without this, forget it.

Theorists write all the popular books on science: Heinz Pagels, Frank Wilczek, Stephen Hawking, Richard Feynman, et al. And why not? They have all that spare time.

Physics isn't a religion. If it were, we'd have a much easier time raising money.

The physicists defer only to mathematicians, and the mathematicians defer only to God.

I sometimes think about the tower at Pisa as the first particle accelerator, a (nearly) vertical linear accelerator that Galileo used in his studies.

Those who do not stop asking silly questions become scientists.

We hope to explain the entire universe in a single, simple formula that you can wear on your T-shirt.

Science should have no less lofty a goal. My ambition is to live to see all of physics reduced to a formula so elegant and simple that it will fit easily on the front of a T-shirt.

My children have often asked me why I never received a Nobel Prize. I used to tell them it was because the Nobel committee couldn’t make up its mind which of my projects to recognize.

I'm so old I can remember when the Dead Sea was only sick.

Neutrinos ... win the minimalist contest: zero charge, zero radius, and very possibly zero mass.

But how sane can the mind really be if it doesn't even know its own depth?

I know what it feels like to miss everything about him--the way he smells, the way his mouth curls up when he laughs, his voice.

All rivers pay homage to the ocean for it lies lowest.

Something that confirms all fears and many conspiracy theories about government is finding out what our elected representatives would put into law if they could.

There was a law in Connecticut - I believe it is still formally unrepealed - making it illegal for a man to kiss his wife on Sunday.

When I go on a nostalgia trip it's not aesthetic. For me it's about trying to recapture the smell or the feeling of something that I've experienced in the past personally.

Wars should be over in three days or less...and the American people must be all for it from the outset.

I think everybody's book is about somebody's daughter, in a lot of ways. I dig that.

I just try to do what I do best, contribute to my team.

Live life to the fullest. It's too bad we're not cats...we only have one life.
