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.

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.

I am now convinced that theoretical physics is actually philosophy.

The NFL today has bigger, stronger, bodies than ever, moving faster than ever, hitting a stationary object harder than ever before - so the physics of the hit have changed.

Physics is, hopefully, simple. Physicists are not.

The creation of Physics is the shared heritage of all mankind. East and West, North and South have equally participated in it.

The growth of technology is such that it is not possible today for a nuclear physicist to switch into medical physics without training. The field is now much more technical. More training is needed to do the job.

It is funny that men who are supposed to be scientific cannot get themselves to realise the basic principle of physics, that action and reaction are equal and opposite, that when you persecute people you always rouse them to be strong and stronger.

It should be possible to explain the laws of physics to a barmaid.

Industrial opportunities are going to stem more from the biological sciences than from chemistry and physics. I see biology as being the greatest area of scientific breakthroughs in the next generation.

Indubitably, magic is one of the subtlest and most difficult of the sciences and arts. There is more opportunity for errors of comprehension, judgment and practice than in any other branch of physics.

Most medical physicists work in the physics of radiation oncology making sure that the desired dose is given to the cancer and the dose to normal tissues are minimized.

There are several books that I have-the Physics of Star Trek, Star Trek and Business, there are manuals on command style and countless scholarly papers that have been written about the significance of Next Generation.

It is wrong to think that the task of physics is to find out how Nature is. Physics concerns what we say about Nature.

Well, I'm leaning probably toward the sciences like physics.

When modern physics exerts itself to establish the world's formula, what occurs thereby is this: the being of entities has resolved itself into the method of the totally calculable.

It's always a combination of physics and poetry that I find inspiring. It's hard to wrap your head around things like the Hubble scope.

Chemistry has been termed by the physicist as the messy part of physics, but that is no reason why the physicists should be permitted to make a mess of chemistry when they invade it.

And the actual achievements of biology are explanations in terms of mechanisms founded on physics and chemistry, which is not the same thing as explanations in terms of physics and chemistry.

If anybody says he can think about quantum physics without getting giddy, that only shows he has not understood the first thing about them.

In 1948 I entered the Massachusetts Institute of Technology, undecided between studies of chemistry and physics, but my first year convinced me that physics was more interesting to me.

This book is about physics and its about physics and its relationship with mathematics and how they seem to be intimately related and to what extent can you explore this relationship and trust it.

Quantum physics thus reveals a basic oneness of the universe.

The laws of physics should allow us to arrange things molecule by molecule and even atom by atom, and at some point it was inevitable that we would develop a technology that would let us do this.

In 1948 I was appointed to a Lectureship in Physics and in 1949 elected to a Fellowship at Trinity College.
