So the thing I realized rather gradually - I must say starting about 20 years ago now that we know about computers and things - there's a possibility of a more general basis for rules to describe nature.

I sit astride life like a bad rider on a horse. I only owe it to the horse's good nature that I am not thrown off at this very moment.

If I take the theory as we have it now, literally, I would conclude that extra dimensions really exist. They're part of nature. We don't really know how big they are yet, but we hope to explore that in various ways.

Even before string theory, especially as physics developed in the 20th century, it turned out that the equations that really work in describing nature with the most generality and the greatest simplicity are very elegant and subtle.

String theory is an attempt at a deeper description of nature by thinking of an elementary particle not as a little point but as a little loop of vibrating string.

The scientist's inquiry into the causes of things is providing an ever more extensive understanding of nature.

Without Liberty, Law loses its nature and its name, and becomes oppression. Without Law, Liberty also loses its nature and its name, and becomes licentiousness.

Nature holds the key to our aesthetic, intellectual, cognitive and even spiritual satisfaction.

A vacuum is a hell of a lot better than some of the stuff that nature replaces it with.

Baseball gives every American boy a chance to excel, not just to be as good as someone else but to be better than someone else. This is the nature of man and the name of the game.

Spring is nature's way of saying, "Let's party!"

I don't think I'll ever be able to stay in one place for more than a year or two. It's not in my nature.

Nature reserves the right to inflict upon her children the most terrifying jests.

Another thing I like to do is sit back and take in nature. To look at the birds, listen to their singing, go hiking, camping and jogging and running, walking along the beach, playing games and sometimes being alone with the great outdoors. It's very special to me.

It takes so long to train a physicist to the place where he understands the nature of physical problems that he is already too old to solve them.
