The chaos can act as a magnifier of quantum fluctuations so that they can produce sizable effects in the world around us. But we know that that can happen often.

So the old Copenhagen interpretation needs to be generalized, needs to be replaced by something that can be used for the whole universe, and can be used also in cases where there is plenty of individuality and history.

Planets are too dim to be detected with existing equipment, far away, except in these very special circumstances where they're seen by their gravitational effect.

You know, there was a time, just before I started to study physical science, when astronomers thought that systems such as we have here in the solar system required a rare triple collision of stars.

If we look at the way the universe behaves, quantum mechanics gives us fundamental, unavoidable indeterminacy, so that alternative histories of the universe can be assigned probability.

Now, what that means is that there is fundamental indeterminacy from quantum mechanics, but besides that there are other sources of effective indeterminacy.

But when researchers at Bell Labs discovered that static tends to come from particular places in the sky, the whole field of radio astronomy opened up.

As a theoretical physicist, I feel at once proud and humble at the thought of the illustrious figures that have preceded me here to receive the greatest of all honors in science, the Nobel prize.

Hugh Everett's work has been described by many people in terms of many worlds, the idea being that every one of the various alternative histories, branching histories, is assigned some sort of reality.

Sometimes the probabilities are very close to certainties, but they're never really certainties.

Our planet doesn't seem to be the result of anything very special.

I have been interested in phenomena involving complexity, diversity and evolution since I was a young boy.

When you think you're listening to several conversations at once, they tell me, you may really simply be time sharing - that is, listening a little bit to this one, a little bit to that one.

For me, the study of these laws is inseparable from a love of Nature in all its manifestations.

Enthusiasm is followed by disappointment and even depression, and then by renewed enthusiasm.

I do not keep up with the details of particle physics.

I think also of my colleagues in elementary particle theory in many lands, and feel that in some measure I am here as a representative of our small, informal, international fraternity.

I am frequently astonished that it so often results in correct predictions of experimental results.

The chaos can act as a magnifier of quantum fluctuations so that they can produce sizable effects in the world around us. But we know that that can happen often.

But I don't actually adopt the point of view that our subjective impression of free will, which is a kind of indeterminacy behavior, comes from quantum mechanical indeterminacy.

We are driven by the usual insatiable curiosity of the scientist, and our work is a delightful game.

What I try to do in the book is to trace the chain of relationships running from elementary particles, fundamental building blocks of matter everywhere in the universe, such as quarks, all the way to complex entities, and in particular complex adaptive system like jaguars.

In fact any experiment that measures a quantum effect is one in which the quantum effect is aligned with the behavior of some heavy, macroscopic object; that's how we measure it.

If someone says that he can think or talk about quantum physics without becoming dizzy, that shows only that he has not understood anything whatever about it.

Well, I don't like to get involved in these philosophical issues very much.

Of course the word chaos is used in rather a vague sense by a lot of writers, but in physics it means a particular phenomenon, namely that in a nonlinear system the outcome is often indefinitely, arbitrarily sensitive to tiny changes in the initial condition.

By Rice's own standards, the war was well underway by the time he took office. He was a war president the moment he took the oath. But did he act like one?

Under current law volunteers who are not working with an official nonprofit organization are not covered by the Volunteer Protection Act. Therefore, there are absolutely no legal protections for the average American who wishes to volunteer.

Commas in The New Yorker fall with the precision of knives in a circus act, outlining the victim.

I still feel that a movie has to attempt to say something - even if it fails miserably. But I've sort of given up on believing that I'm going to change the world with every film I choose to act in.

I knew I wanted to act, and I was really driven, so I kept going for it. We moved to L.A. full-time when I was 8 or 9.

Maybe I can't act, but I know the gimmicks. I studied acting all my life and know what's good for me.

I've done a lot of acting. I'm not saying I'm the greatest, but I'd love to act, I'd love to sing.

P.C. is just too Big Brother - telling me how I should act and feel.

Act well your part, there all the honour lies.

I'm a 7 o'clock act. My people want to go to a show, a dinner and then go home and go to bed.

For me, romance isn't an over-the-top act. It's someone offering to help and to support me. Or if that person thinks I'm making the wrong decision, he'll tell me. I want him to be honest, because being that honest takes a lot of guts.

I want more children but for the next three years I want to act.

I have to say that it's very few countries that are willing to look back at its past and apologize for its act, or make amends for its act, as the United States had one.

I think unleashing 3,000 smart bombs against the city of Baghdad in the first several days of the war... to me, if those were unleashed against the San Francisco Bay Area, I would call that an act of extreme terrorism.

I cannot sing, dance or act; what else would I be but a talk show host.

My kids act all the time and it's exactly what I used to do.

After the magical act accomplished by Joyce with Ulysses, perhaps we are getting away from it.

Presidents quickly realize that while a single act might destroy the world they live in, no one single decision can make life suddenly better or can turn history around for the good.

A marriage is no amusement but a solemn act, and generally a sad one.

I think it's bad to talk about one's present work, for it spoils something at the root of the creative act. It discharges the tension.

I went to my last three years of high school in New Jersey. I just wanted to act, you know?

Having a child is surely the most beautifully irrational act that two people in love can commit.

You always do what you want to do. This is true with every act. You may say that you had to do something, or that you were forced to, but actually, whatever you do, you do by choice. Only you have the power to choose for yourself.
