J. Robert Oppenheimer Quotes

There's something called From 'Alchemy to Quarks,' which will teach you everything you have to know, you want to know, about physics.

It is just physics - who can argue with Newton and the first law of thermodynamics?

I like physics. I think it is the best science out of all three of them, because generally it's more useful. You learn about speed and velocity and time, and that's all clever stuff.

Physics without mathematics is meaningless.

Physics has the cutest words.

What goes up must come down.

Before the discovery of quantum mechanics, the framework of physics was this: If you tell me how things are now, I can then use the laws of physics to calculate, and hence predict, how things will be later.

Electrical science has disclosed to us the more intimate relation existing between widely different forces and phenomena and has thus led us to a more complete comprehension of Nature and its many manifestations to our senses.

Weight, force and casual impulse, together with resistance, are the four external powers in which all the visible actions of mortals have their being and their end.

The same law takes place in a system, consisting of many bodies, as in one single body, with regard to their persevering in their state of motion or of rest. For the progressive motion, whether of one single body or of a whole system of bodies, is always to be estimated from the motion of the center of gravity.

In bodies moved, the motion is received, increased, diminished, or lost, according to the relations of the quantity of matter and velocity; each diversity is uniformity, each change is constancy.

Another mode of accumulating power arises from lifting a weight and then allowing it to fall.

Though we may never be able to comprehend human life, we know certainly that it is a movement, of whatever nature it be. The existence of movement unavoidably implies a body which is being moved and a force which is moving it. Hence, wherever there is life, there is a mass moved by a force. All mass possesses inertia; all force tends to persist.

Whenever you say you're a physicist, there's a certain fraction of people who immediately go, 'Oh, I hated physics in high school.' That's because of the terrible influence of high school physics. Because of it, most people think physics is all about inclined planes and force-vector diagrams.

In order to lift a certain object from the ground, we have to use energy. But then to sustain it at that level, we have to keep on adding energy, or otherwise, the object falls to the ground. It's exactly the same thing with the sound.

Our annual school physics trip was always to Blackpool Pleasure Beach, as it's such a good example of Newtonian physics. You can learn about centrifugal force and Newton's first law from the roller coasters, and the Viking long boat is a giant pendulum. It's good for children to understand that science underpins all these brilliant things.

I love physics.

Momentum,' She repeats. 'You can't just stand there if you want something to fly. You have to run.

Momentum solves 80% of your problems.

But in physics I soon learned to scent out the paths that led to the depths, and to disregard everything else, all the many things that clutter up the mind, and divert it from the essential. The hitch in this was, of course, the fact that one had to cram all this stuff into one's mind for the examination, whether one liked it or not.

The day I went into physics class it was death.

I figured it out eventually," she says. She's sitting on the edge of the gurney again; her features slowly materialize as my vision clears. "It's momentum." "What?" I whisper. The feeling returning to my lips, spreading out to my fingertips and toes. "Momentum," she repeats. "You can't just stand there if you want something to fly. You have to run.

All great results in our universe are founded in motions and forces the most minute.

Bowling is all physics and energy distribution. It's F = ma. So it is actually one of the most science-y sports, because it literally is just a ball and a surface and objects to knock down.

If your theory is found to be against the second law of theromodynamics, I give you no hope; there is nothing for it but to collapse in deepest humiliation.
