Motion Quotes - page 29
The distinction, between what is done by labour, and what is done by nature, is not always observed.
Labour produces its effects only by conspiring with the laws of nature.
It is found that the agency of man can be traced to very simple elements. He does nothing but produce motion. He can move things towards one another, and he can separate them from one another. The properties of matter perform the rest.
James Mill
Man himself is an enigma in motion; his questions never stay asked; whereas the mold, the footprint, and by natural extension, the statue itself, like the vaults, the arches, the temples with which man records his own passing, remain immobile and fix a moment of man's life, upon which one might endlessly meditate.
Émile Chartier
There is, in nature, perhaps nothing older than motion, concerning which the books written by philosophers are neither few nor small; nevertheless I have discovered by experiment some properties of it which are worth knowing and which have not hitherto been either observed or demonstrated.
Galileo Galilei
He kept flinching. The low sun shone in the face of a two-hundred-foot-tall wind turbine in the field across the crick, and its blades cast long scything shadows over them. ... The sun above blinking on and off with each cut of a blade. ... Something about their being in motion, in a place where everything else was almost pathologically still, seized the attention; they always seemed to be jumping out at you from behind corners.
Neal Stephenson
[W]e live... in the pockets of reducibility. ...I should have realized [that] very many years ago, but didn't... [I]t could very well be that everything about the world is computationally irreducible and completely unpredictable, but... in our experience of the world there is at least some amount of prediction we can make. ...[T]hat's because we have ...chosen a slice of ...how to think about the universe, in which we can... sample a certain amount of computational reducibility, and that's... where we exist. ...It may not be the whole story about how the universe is, but it is that part of the universe that we care about and ...operate in. ...In science, that's been ...a very special case ...science has chosen to talk a lot about places where there is this computational reducibility... The motion of the planets can be ...predicted. The... weather is much harder to predict. ...[S]cience has tended to concentrate itself on places where its methods have allowed successful prediction.
Stephen Wolfram
Insanity is often the logic of an accurate mind overtasked. Good mental machinery ought to break its own wheels and levers, if anything is thrust among them suddenly which tends to stop them or reverse their motion. A weak mind does not accumulate force enough to hurt itself; stupidity often saves a man from going mad.
Oliver Wendell Holmes, Sr.
Momentum may be roughly described as quantity motion. A body moving at a speed of say twenty an hour, has a certain quantity of motion. If the body goes forty miles an hour there is twice as motion; or if twice as much matter goes twenty miles hour, there is also twice as much motion. Momentum is measured by the quantity of matter moving at a rate mass \times velocity.
William Kingdon Clifford
