Johannes Kepler Quotes

Every particle of matter is attracted by or gravitates to every other particle of matter with a force inversely proportional to the squares of their distances.

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

Any two particles in the universe attract each other through the gravitational interaction.

If the earth were not round, heavy bodies would not tend from every side in a straight line towards the center of the earth, but to different points from different sides.

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.

And then everything was in the hands of gravity, which has never had much love for the terminally stupid.

wheresoever the earth may be placed, or whithersoever it may be carried by its animal faculty, heavy bodies will always be carried towards it.

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

I have explained the phenomena of the heavens and of our sea by the force of gravity, but I have not yet assigned a cause to gravity.

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.

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.

That body is heavier than another which, in an equal bulk, moves downward quicker.

And the earth self-balanced on her centre hung.

Even the most eminent persons are subject to the laws of gravity.

If the moon and earth were not retained in their orbits by their animal force or some other equivalent, the earth would mount to the moon by a fifty-fourth part of their distance, and the moon fall towards the earth through the other fifty-three parts, and they would there meet, assuming, however, that the substance of both is of the same density.

We see only the simple motion of descent, since that other circular one common to the Earth, the tower, and ourselves remains imperceptible. There remains perceptible to us only that of the stone, which is not shared by us; and, because of this, sense shows it as by a straight line, always parallel to the tower, which is built upright and perpendicular upon the terrestrial surface.

When the forces that hold it together go away, the body must fall.

And I was crying for gravity. It had sent me down the stairs, and I'd thought that meant something, but maybe it was just the direction that all things tend to flow.

I was sitting in a chair in the patent office at Bern when all of a sudden a thought occurred to me: "If a person falls freely he will not feel his own weight." I was startled. This simple thought made a deep impression on me. It impelled me toward a theory of gravitation.

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

Thus far I have explained the phenomena of the heavens and of our sea by the force of gravity, but I have not yet assigned a cause to gravity. Indeed, this force arises from some cause that penetrates as far as the centers of the sun and planets without any diminution of its power to act, and that acts not in proportion to the quantity of the surfaces of the particles on which it acts (as mechanical causes are wont to do) but in proportion to the quantity of solid matter, and whose action is extended everywhere to immense distances, always decreasing as the squares of the distances.

Gravity has taken over me from time to time. But otherwise than that, I'm blessed with good health. That's the bottom line.

The moon is not kept in her orbit round the earth, nor the earth in her orbit round the sun, by a force that varies merely in the inverse ratio of the squares of the distances.

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.
