Physics Quotes - Page 12

As you know, a theory in physics is not useful unless it is able to predict underlined effects which we would otherwise expect.

Therefore psychologically we must keep all the theories in our heads, and every theoretical physicist who is any good knows six or seven different theoretical representations for exactly the same physics.

In its efforts to learn as much as possible about nature, modern physics has found that certain things can never be "known" with certainty. Much of our knowledge must always remain uncertain. The most we can know is in terms of probabilities.

In physics the truth is rarely perfectly clear, and that is certainly universally the case in human affairs. Hence, what is not surrounded by uncertainty cannot be the truth.

I've always thought that one of the the great thing about physics is that you can add more digits to any number and see what happens and nobody can stop you.

We live, I think, in the century of science and, perhaps, even in the century of physics.

As an undergraduate, I did maths and physics. That doesn't make me a scientist. So I try to read and understand and talk to scientists.

Quantum physics fluctuates all the time. But now the fluctuations are not just particles coming into and out of existence, which happens all the time. It's whole universes coming into and out of existence.

Ultimately, my Ph.D. is in mathematical physics, focusing on quantum field theory and curved space-time, and I worked with Stephen Hawking.

Think how hard physics would be if particles could think

Pablo Picasso said, "Art is the lie that tells the truth," and it's not a terribly radical statement. It's always been that you can tell truth through fiction. And this idea also comes from nuclear physics.

Ever since I was a kid, I've had an enormous interest in the sciences - everything from quantum physics to anthropology.

I would hope that the publicity around the Higgs boson would increase the public awareness of physics and cosmology.

At school I briefly wanted to be a palaeontologist, but I was no good at chemistry and physics.

Ronan didn't need physics. He could intimidate even a piece of plywood into doing what he wanted.

I'm a bit of a layman physics junkie. I don't really understand it, but I love trying to understand it.

You watch an old 'Jeopardy!' and the categories alone are very plain. 'Poetry,' or 'Movies,' or 'Physics.' If you watch it now, though, there'll be a theme board where the categories are all Hitchcock movies. Lots more jokes, lots more high-concept categories and questions.

The physics of the 21st century shall deal essentially with non-spatial matter and non-spatial mechanics.

You believe in God? Dude. Only God could have created physics.

Laws of physics laws of love of time and space and the (in)between place (in)between you and me and where we are lost and looking looking and lost

The science behind Interstellar is interesting, because some of it is absolutely real astrophysics and orbital mechanics, some of it is theoretical physics, and some of it is completely Hollywood. When a science fiction movie is based on plausible science, it's really good.

Metaphysics is the science of proving what we don't understand.

Our knowledge of physics only takes us back so far. Before this instant of cosmic time, all the laws of physics or chemistry are as evanescent as rings of smoke.

Going to the moon is not a matter of physics but of economics.

The laws of physics must provide a mechanism for the universe to come into being.
