Tiny differences in input could quickly become overwhelming differences in output.... In weather, for example, this translates into what is only half-jokingly known as the Butter- fly Effectโthe notion that a butterfly stirring the air today in Peking can transform storm systems next month in New York.
James GleickWhen the Lilliputians first saw Gulliver's watch, that "wonderful kind of engine...a globe, half silver and half of some transparent metal," they identified it immediately as the god he worshiped. After all, "he seldom did anything without consulting it: he called it his oracle, and said it pointed out the time for every action in his life." To Jonathan Swift in 1726 that was worth a bit of satire. Modernity was under way. We're all Gullivers now. Or are we Yahoos?
