Notable Quotations and Concepts
"Here was the end of an evolution almost as long as Man's. Its beginnings were lost in the mists of the Dawn Ages, when humanity had first learned the use of power and sent its noisy engines clanking about the world. Steam, water, wind-all had been harnessed for a little while and then abandoned. For centuries the energy of matter had run the world until it too had been superseded, and with each change the old machines were forgotten and new ones took their place. Very slowly, over thousands of years, the ideal of the perfect machine was approached-that ideal which had once been a dream, then a distant prospect, and at last reality: No machine may contain any moving parts. Here was the ultimate expression of that ideal. Its achievement had taken Man perhaps a hundred million years, and in the moment of his triumph he had turned his back upon the machine forever. It had reached finality, and thenceforth could sustain itself eternally while serving him."In the passage above, Clarke describes the Central Computer that maintains Diaspar in an unchanging state, and refers to the end of all evolution and the apparent creation of a perfect society.
Jeserac sat motionless within a whirlpool of numbers. The first thousand primes.... Jeserac was no mathematician, though sometimes he liked to believe he was. All he could do was to search among the infinite array of primes for special relationships and rules which more talented men might incorporate in general laws. He could find how numbers behaved, but he could not explain why. It was his pleasure to hack his way through the arithmetical jungle, and sometimes he discovered wonders that more skillful explorers had missed. He set up the matrix of all possible integers, and started his computer stringing the primes across its surface as beads might be arranged at the intersections of a mesh.In this passage, Clarke describes the prime spiral, a method of graphing the prime numbers that reveals a pattern, seven years before it was discovered by Stanislaw Ulam. Apparently, Clarke did not notice the pattern revealed by the Prime Spiral because he "never actually performed this thought experiment."
The fact that Clarke's protagonist was ale to identify environmental issues within the fictional world illustrates Clarke's own attitude towards the issue. When Clarke moved away from his place of birth, one thing he commented on was the breath of nature.

Famous quotes containing the words notable, quotations and/or concepts:
“In one notable instance, where the United States Army and a hundred years of persuasion failed, a highway has succeeded. The Seminole Indians surrendered to the Tamiami Trail. From the Everglades the remnants of this race emerged, soon after the trail was built, to set up their palm-thatched villages along the road and to hoist tribal flags as a lure to passing motorists.”
—For the State of Florida, U.S. public relief program (1935-1943)
“Reading any collection of a man’s quotations is like eating the ingredients that go into a stew instead of cooking them together in the pot. You eat all the carrots, then all the potatoes, then the meat. You won’t go away hungry, but it’s not quite satisfying. Only a biography, or autobiography, gives you the hot meal.”
—Christopher Buckley, U.S. author. A review of three books of quotations from Newt Gingrich. “Newtie’s Greatest Hits,” The New York Times Book Review (March 12, 1995)
“It is impossible to dissociate language from science or science from language, because every natural science always involves three things: the sequence of phenomena on which the science is based; the abstract concepts which call these phenomena to mind; and the words in which the concepts are expressed. To call forth a concept, a word is needed; to portray a phenomenon, a concept is needed. All three mirror one and the same reality.”
—Antoine Lavoisier (1743–1794)
