Terry Pratchett Quotes

I've been noticing gravity since I was very young.

Gravity wins over all other known forces.

We know there is gravity because apples fall from trees. We can observe gravity in daily life. If we could throw an apple to the edge of the universe, we would observe it accelerating.

Gravity is more powerful where there's more stuff.

Everything every day here on Earth is based on gravity, and you don't realize it until you don't have it anymore.

Gravity is more suggestive than convincing.

Gravity is matter’s sugar daddy.

There is still some gravity where we are and even as far out as our moon. That is why our moon stays in orbit around the Earth. We don't feel the gravity up here because it is so much smaller than the force we feel when we are on the Earth.

In the school I went to, they asked a kid to prove the law of gravity and he threw the teacher out of the window.

I suppose I'll have to add the force of gravity to my list of enemies.

Centripetal force is the force by which bodies are drawn from all sides, are impelled, or in any way tend, toward some point as to a center.

Weight is caused by one element being situated in another; and it moves by the shortest line towards its centre, not by its own choice, not because the centre draws it to itself, but because the other intervening element cannot withstand it.

Physics has the cutest words.

Acceleration is finite, I think according to some laws of physics.

My physics teacher, Thomas Miner was particularly gifted. To this day, I remember how he introduced the subject of physics. He told us we were going to learn how to deal with very simple questions such as how a body falls due to the acceleration of gravity.

The black holes of nature are the most perfect macroscopic objects there are in the universe: the only elements in their construction are our concepts of space and time.

Gravitation is, so far, not understandable in terms of other phenomena.

You can be only a modest distance away from the gravity brane, and gravity will be incredibly weak.

Black holes are very exotic objects. Technically, a black hole puts a huge amount of mass inside of zero volume. So our understanding of the center of black holes doesn't make sense, which is a big clue to physicists that we don't have our physics quite right.

Gravity is one variable in a lot of scientific processes. If you can remove gravity or minimize its effect, then you can understand the other processes that are going on.

The universe is composed of matter, and, as a system, is sustained by motion. Motion is not a property of matter, and without this motion the solar system could not exist.

Millions saw the apple fall but Newton was the one who asked 'why.'

Some of the best scientists can't explain gravity; Neil Degrasse Tyson, Bill Nye, in the end, do they even know?

You think Earth's gravity is really something when you're climbing the stairs. But, as far as physics goes, it is a pipsqueak, infinitesimal, tiny little effect.

I love physics.
