Famous quotes containing the words science and/or technology:
“We would be a lot safer if the Government would take its money out of science and put it into astrology and the reading of palms.... Only in superstition is there hope. If you want to become a friend of civilization, then become an enemy of the truth and a fanatic for harmless balderdash.”
—Kurt Vonnegut, Jr. (b. 1922)
“The real accomplishment of modern science and technology consists in taking ordinary men, informing them narrowly and deeply and then, through appropriate organization, arranging to have their knowledge combined with that of other specialized but equally ordinary men. This dispenses with the need for genius. The resulting performance, though less inspiring, is far more predictable.”
—John Kenneth Galbraith (b. 1908)
