Quotes About Physics

Physics is often stranger than science fiction, and I think science fiction takes its cues from physics: higher dimensions, wormholes, the warping of space and time, stuff like that.

The laws of science do not distinguish between the past and the future.

It is hard to see how one could begin to develop a quantum-theoretical description of brain action when one might well have to regard the brain as "observing itself" all the time!

Formerly, people thought that if matter disappeared from the universe, space and time would remain. Relativity declares that space and time would disappear with matter.

Arc, amplitude, and curvature sustain a similar relation to each other as time, motion, and velocity, or as volume, mass, and density.

As of now, string theorists have no explanation of why there are three large dimensions as well as time, and the other dimensions are microscopic. Proposals about that have been all over the map.

Heat can never pass from a colder to a warmer body without some other change, connected therewith, occurring at the same time.

A great physicist taught at the Massachusetts Institute of Technology. He published many important books and papers. Often he had an idea in the middle of the night. He rose from his bed, took a shower, washed his hair, and shaved. He dressed completely, in a clean shirt, in polished shoes, a jacket and tie. Then he sat at his desk and wrote down his idea. A friend of mine asked him why he put himself through all that rigmarole. 'Why,' he said, surprised at the question, 'in honor of physics!

Relieved of this easily measured outcome, I could focus on the practice alone. I focused on the rhythm, on my posture, on the magic of the physics of casting. At some point, the professional has to bring home the fish. That's the fuel that permits the professional to show up each day. But the catch is the side effect of the practice itself. Get the practice right, and your commitment will open the door for the market to engage with your work.

The computational universe is not an alternative to the physical universe. The universe that evolves by processing information and the universe that evolves by the laws of physics are one and the same. The two descriptions, computational and physical, are complementary ways of capturing the same phenomena.

Quantum fluctuations are the monkeys that program the universe.

The labor we delight in physics pain.

language that felt linked to my experience. In the sixties, the physicist John Stewart Bell theorized that particles that were once connected will, when separated, behave as if still connected, regardless of the distance between them. Some years later a French physicist, Alain Aspect, conducted experiments offering physical proof of Bell's theorem.

In case you haven't noticed, they're moving a lot faster. I don't know about the laws of physics on your planet, but where I come from an object moving at subclass speed can't catch up to one running at starclass. But if you know something about turbines, thrusters and engines, quantum or classical physics that I've somehow missed, then please enlighten me. - Caillen Dagan to Desideria Denarii

The real thing that physics tell us about the universe is that it's big, rare event happens all the time — including life — and that doesn't mean it's special.

This minimum, the so-called critical mass, turned out to be a surprisingly small 4 kg, about the size of an apple.

How many of you have broken no laws this month? That's the kind of society I want to build. I want a guarantee - with physics and mathematics, not with laws - that we can give ourselves real privacy of personal communications.

Now, I'd like to ask people in the room, please raise your hand if you have not broken a law, any law, in the past month... That's the kind of society I want to build. I want to guarantee — with physics and mathematics, not with laws — that we can give ourselves real privacy of personal communications.

In the world of the very small, where particle and wave aspects of reality are equally significant, things do not behave in any way that we can understand from our experience of the everyday world...all pictures are false, and there is no physical analogy we can make to understand what goes on inside atoms. Atoms behave like atoms, nothing else.

It isn't just that Bohr's atom with its electron "orbits" is a false picture; all pictures are false, and there is no physical analogy we can make to understand what goes on inside atoms. Atoms behave like atoms, nothing else.

Sir Arthur Eddington summed up the situation brilliantly in his book The Nature of the Physical World, published in 1929. "No familiar conceptions can be woven around the electron," he said, and our best description of the atom boils down to "something unknown is doing we don't know what".

Every problem in quantum physics had to be first "solved" using classical physics, and then be reworked by the judicious insertion of quantum numbers more by inspired guesswork than cool reasoning.

If the business of physics is ever finished, the world will be a much less interesting place in which to live . . .

The lack of solutions to the Three-Body Problem is not caused by our human deficiencies as mathematicians, it is build into the laws of mathematics.
