Motion Quotes - page 8
I always saw a close kinship between the needs of "pure" mathematics and a certain hero of Greek mythology, Antaeus. The son of Earth, he had to touch the ground every so often in order to reestablish contact with his Mother; otherwise his strength waned. To strangle him, Hercules simply held him off the ground. Back to mathematics. Separation from any down-to-earth input could safely be complete for long periods - but not forever. In particular, the mathematical study of Brownian motion deserved a fresh contact with reality.
Benoît Mandelbrot
From the beginning I could not believe that the "efficient market” hypothesis was dependent on a pure Brownian motion white noise or any truly random random walk. Place a minuscule colloidal molecule on a horizontal table that covers unlimited acres. Bombard it from every direction with thousands of minute atoms; and then if you wait long enough that original molecule can have traveled a billion miles in one direction. That's truly a random Bachelier-Einstein walk, but not my notion of economic fluctuations.
Paul Samuelson
The main difficulty in using either lazo or bolas, is to ride so well, as to be able at full speed, and while suddenly turning about, to whirl them so steadily round the head, as to take aim: on foot any person would soon learn the art. One day, as I was amusing myself by galloping and whirling the balls round my head, by accident the free one struck a bush; and its revolving motion being thus destroyed, it immediately fell to the ground, and like magic caught one hind leg of my horse; the other ball was then jerked out of my hand, and the horse fairly secured. Luckily he was an old practised animal, and knew what it meant; otherwise he would probably have kicked till he had thrown himself down. The Gauchos roared with laughter; they cried they had seen every sort of animal caught, but had never before seen a man caught by himself.
Charles Darwin
Intelligent creatures [that] evolved to live deep within the atmosphere of a gas giant planet could be deluded, for eons, into thinking that the Universe is an approximately homogeneous expanse of gas, filling a three-dimensional space, but featuring anisotropic laws of motion (which we would ascribe to the planet's gravitational field). Are we human scientists comparably blinkered?
Frank Wilczek
In a sense, all of Earth glows in the dark. The energy release from natural radioactivity, the lingering fluorescence of stellar explosions, keeps Earth dynamic. It melts the core and keeps it flowing, and heats the crust and mantle, with consequences ranging from the generation of earth's magnetic field to earthquakes and the motion of continents. By contrast, Luna and Mars, because they are smaller, derive less energy from radioactive decays. Geologically, they are dead.
Frank Wilczek
In the thousands of articles that made up the technical literature of chaos, few were cited more often than "Deterministic Nonperiodic Flow." For years, no single object would inspire more illustrations, even motion pictures, than the mysterious curve depicted at the end, the double spiral that became known as the Lorenz attractor.
James Gleick
The Pennsylvania legislature, who, on a proposition to make the belief in God a necessary qualification for office, rejected it by a great majority, although assuredly there was not a single atheist in their body. And you remember to have heard, that when the act for religious freedom was before the Virginia Assembly, a motion to insert the name of Jesus Christ before the phrase, "the author of our holy religion," which stood in the bill, was rejected, although that was the creed of a great majority of them.
Thomas Jefferson
I had always hoped that the younger generation receiving their early impressions after the flame of liberty had been kindled in every breast, & had become as it were the vital spirit of every American, that the generous temperament of youth, analogous to the motion of their blood, and above the suggestions of avarice, would have sympathized with oppression wherever found, and proved their love of liberty beyond their own share of it.
Thomas Jefferson
I have seen the astrolabe called Zuraqi invented by Abu Sa'id Sijzi. I liked it very much and praised him a great deal, as it is based on the idea entertained by some to the effect that the motion we see is due to the Earth's movement and not to that of the sky. By my life, it is a problem difficult of solution and refutation. [...] For it is the same whether you take it that the Earth is in motion or the sky. For, in both cases, it does not affect the Astronomical Science. It is just for the physicist to see if it is possible to refute it.
Al-Biruni
He was an actor of genius. There was no more overwhelming actor on the stage, in the motion pictures, nor even in the pulpit. He would whirl arms, bang tables, glare from mad eyes, vomit Biblical wrath from a gaping mouth; but he would also coo like a nursing mother, beseech like an aching lover, and in between tricks would coldly and almost contemptuously jab his crowds with figures and facts-figures and facts that were inescapable even when, as often happened, they were entirely incorrect.
Sinclair Lewis
A person must have lost his mind to believe in God. The product of either fear or weakness, this abominable phantom, Eugenie, is useless for the system of the earth, It would even be infallibly harmful. You see, its will, which must be just, could never ally itself with the injustice essential to the laws of nature. It would constantly have to wish for goodness, which nature desires only as compensation for the evil that serves its laws. It would have to act continuously, and nature, one of whose laws is that perpetual motion, could only rival and perpetually resist it.
Marquis de Sade
How came the king by a power which the people are afraid to trust, and always obliged to check? Such a power could not be the gift of a wise people, neither can any power, which needs checking, be from God; yet the provision, which the constitution makes, supposes such a power to exist. But the provision is unequal to the task; the means either cannot or will not accomplish the end, and the whole affair is a felo de se; for as the greater weight will always carry up the less, and as all the wheels of a machine are put in motion by one, it only remains to know which power in the constitution has the most weight, for that will govern; and though the others, or a part of them, may clog, or, as the phrase is, check the rapidity of its motion, yet so long as they cannot stop it, their endeavors will be ineffectual; the first moving power will at last have its way, and what it wants in speed is supplied by time.
Thomas Paine
