Quotes About Physics

Theoretical and experimental physicists are now studying nothing at all-the vacuum. But that nothingness contains all of being.

We all know we fall. Newton's discovery was that the moon falls, too-and by the same rule that we do.

We may as well cut out group theory. That is a subject that will never be of any use in physics.

Oh, I never use a seat belt. I don't believe in gravity.

For every action, there is an equal and opposite reaction.

Black holes collect problems faster than they collect matter.

Mathematics began to seem too much like puzzle solving. Physics is puzzle solving, too, but of puzzles created by nature, not by the mind of man.

In fact a favourite problem of [John Tyndall] is—Given the molecular forces in a mutton chop, deduce Hamlet or Faust therefrom. He is confident that the Physics of the Future will solve this easily.

Life is a physics problem. Bodies in motion.

One may characterize physics as the doctrine of the repeatable, be it a succession in time or the co-existence in space. The validity of physical theorems is founded on this repeatability.

The expression e=mc2 is the ultimate statement in bounce per ounce.

The algebraic sum of all the transformations occurring in a cyclical process can only be positive, or, as an extreme case, equal to no

All science is either Physics or stamp-collecting.

The laissez-faire attitude to science education has resulted in a disaster exemplified by the fact that more young people are opting for media studies than physics.

Paul Dirac was notoriously a man of few words. Dick Feynman told the story that when he first met Dirac at a conference, Dirac said after a long silence, "I have an equation; do you have one too?

Biz insanlar evrenin belli gerçeklerini ölçebilecek becerilere sahip deÄŸiliz. Yani, olaylar her ne kadar rastgele görünse de tamamen fiziksel gerçekliklerle koÅŸulland?r?lm??lard?r ve böyle belirlenirler.

It was exciting and intellectually gratifying to speculate on what might lie waiting in the black gulfs when one was behind the business end of a telescope, quite another to do so isolated on an unpleasant little speck of a world such as this, confronted by a ship of non-human manufacture that uncomfortably resembled a growth instead of a familiar device for manipulating and overcoming the neat laws of physics.

As Vilenkin said to me, quantum physics can produce a universe without cause—just as quantum physics shows how electrons can change orbits in atoms without cause. There are no definite cause-and-effect relationships in the quantum world, only probabilities

Carroll and other physicists believe that order is intimately connected to the "arrow" of time. In particular, the forward direction of time is determined by the movement of order to disorder.

with the behavior of the universe before the Big Bang a nearly mirror image of its behavior after the Big Bang. Until fourteen billion years ago, the universe was contracting. It reached a minimum size at the Big Bang (which we call t = 0) and has been expanding ever since, like a Slinky that falls to the floor, reaches a maximum compression upon impact, and then bounces back to larger dimensions.

Because of the hazy, nondefinite character of quantum physics (called the Heisenberg uncertainty principle), at the dimensions of the Planck length, space and time churn and seethe, with the distance between any two points wildly fluctuating from moment to moment, and time randomly speeding and slowing, perhaps even going backward and forward. In such a situation, time and space no longer exist in a way that has meaning to us.

There's no point worrying about it now, at any rate. Things tend to sort themselves out, Alma thinks, although she knows that this directly contradicts the laws of physics, common sense, and her political experience of the last forty years.

Physics is the science of all the tremendously powerful invisibilities - of magnetism, electricity, gravity, light, sound, cosmic rays. Physics is the science of the mysteries of the universe. How could anyone think it dull?

The body thinks it's real. That's the problem of modern physics. How to convince our minds that they're not our own.
