Quotes About Physics

We have these words 'space' and 'time,' but you can't touch them. They're not objects, they're not things, they go forever. Space and time are really tools of animal sense perception, the way we organize and construct information.

Keep in mind that if you take a tour through a hospital and look at every machine with on and off switch that is brought into the service of diagnosing the human condition, that machine is based on principles of physics discovered by a physicist in a machine designed by an engineer.

The moon gravitates towards the earth and by the force of gravity is continually drawn off from a rectilinear motion and retained in its orbit.

The standard high school curriculum traditionally has been focused towards physics and engineering. So calculus, differential equations, and linear algebra have always been the most emphasized, and for good reason - these are very important.

As for me, I want to have fun while I'm working. Now not everyone thinks physics is fun, but I do. I think experimental physics is especially fun, because not only do you get to solve puzzles about the universe or on Earth, there are really cool toys in the lab.

We can trace things back to the earlier stages of the Big Bang, but we still don't know what banged and why it banged. That's a challenge for 21st-century science.

Thanks to the fact that the Earth isn't a perfect sphere, and invoking a bunch of Newtonian physics, you can deduce that our planet wobbles, too, taking roughly 26,000 years to trace out a small circle on the sky, a phenomenon known as precession.

No lens is quick enough to track the movement of the human body. The molecules are always moving.

Bosons love to come together; fermions can't stand each other

I admired Bohr very much. We had long talks together, long talks in which Bohr did practically all the talking.

I have experimental evidence that time travel is not possible.

You had to be able to lift yourself outside of the time stream - and that essentially became what is called the yoga of time travel.

The bottom line is that time travel is allowed by the laws of physics.

Don't waste your time on beaming people up or down. Instead, consider gravity waves as advanced physics of the universe that could be used to travel interstellar distances.

Originally, the burden of proof was on physicists to prove that time travel was possible. Now the burden of proof is on physicists to prove there must be a law forbidding time travel.

Geography is just physics slowed down, with a couple of trees stuck in it.

My intention was to enroll at McGill University but an unexpected series of events led me to study physics at the Massachusetts Institute of Technology.

Every body continues in its state of rest or uniform motion in a straight line, except insofar as it doesn't.

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

The fundamental concept in social science is Power, in the same sense in which Energy is the fundamental concept in physics.

The observer, when he seems to himself to be observing a stone, is really, if physics is to be believed, observing the effects of the stone upon himself. Thus science seems to be at war with itself: when it most means to be objective, it finds itself plunged into subjectivity against its will. Naive realism leads to physics, and physics, if true, shows that naive realism is false. Therefore naive realism, if true, is false; therefore it is false.

In the whole theory of the material world, Cartesianism was rigidly deterministic. Living organisms, just as much as dead matter, were governed by the laws of physics; there was no longer need, as in the Aristotelian philosophy, of an entelechy or soul to explain the growth of organisms and the movements of animals. Descartes

We all start from "naive realism," i.e., the doctrine that things are what they seem. We think that grass is green, that stones are hard, and that snow is cold. But physics assures us that the greenness of grass, the hardness of stones, and the coldness of snow are not the greenness of grass, the hardness of stones, and the coldness of snow that we know in our own experience, but something very different

Atoms, by collision, produce vortices, which generate bodies and ultimately worlds.
