Quotes About Physics

Everything is natural, though if we do not know, or if we misread nature's laws, we falsely call it otherwise. Consider: Fifty years ago a man beholding the radio would have called it supernatural, yet the laws of physics governing the device were known as well then as now. But their application had not yet been learned.

If you believe that the atoms that are inside your brain and your body act differently because they are in a living person than if they were in a rock or a crystal, then what you're saying is that the laws of physics are wrong.

In 1965, physicist Richard Feynman opined, "I think I can safely say that nobody understands quantum mechanics," and the sentiment is equally applicable today.

There is a famous joke, attributed to Einstein: "When a man sits with a pretty girl for an hour, it seems like a minute. But let him sit on a hot stove for a minute and it's longer than any hour. That's relativity." I don't know whether Einstein actually ever said those words. But I do know that's not relativity.

It's only because the data force us into corners that we are inspired to create the highly counterintuitive structures that form the basis for modern physics.

Rµv - (1/2)Rgµv = 8?GTµv. This is the equation that a physicist would think of if you said "Einstein's equation"; that E = mc2 business is a minor thing,

Don't play Quantum Russian Roulette.

The strength of the electromagnetic interaction, for example, is fixed by a number called the "fine-structure constant," a famous quantity in physics that is numerically close to 1/137.

Ernest Rutherford, a New Zealand–born experimental physicist who was as responsible as anyone for discovering the structure of the atom, once remarked that "all of science is either physics or stamp collecting.

Space itself is not fundamental; it's just a useful way of talking from certain points of view.

Upon measurement, the wave function collapses. However spread out it may have been pre-measurement, afterward it is concentrated on the result we obtained.

The idea that light is emitted in discrete quanta of energy related to its frequency is puzzling,

We might be able to guarantee that events along a closed timelike curve are consistent with the microscopic laws of physics, but in general they cannot be compatible with an uninterrupted increase of entropy along the curve.

That's the uncertainty principle. It's not that we can't know both quantities at the same time; it's just a fact about how wave functions work that if position is concentrated near some location, momentum is completely undetermined, and vice versa.

The principle that light can be in two places at the same time is absolutely extraordinary.

This change in the conception of reality is the most profound and the most fruitful that physics has experienced since the time of Newton. Refering to James Clerk Maxwell's contributions to physics.

There was a time when we wanted to be told what an electron is. The question was never answered. No familiar conceptions can be woven around the electron; it belongs to the waiting list.

I cannot stress this enough - if you try to install an HDTV in a non-HDTV compatible house, you may tear the space-time continuum.

I do believe it is the first time in history that fire has ever melted steel. I do believe that it defies physics for the World Trade Center Tower Seven, building seven, which collapsed in on itself.

Or in other words, why does disorder increase in the same direction of time as that in which the universe expands?

In real time, the universe has a beginning and an end at singularities that form a boundary to space-time and at which the laws of science break down.

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

Michio Kaku and Albert Einstein, they're both so ahead of our time. It's just fascinating to read about them, what their theories are on loopholes and everything else. It's fascinating stuff.

Relativity theory forced the abandonment, in principle, of absolute space and absolute time.
