Famous quotes containing the word science:
“Science, unguided by a higher abstract principle, freely hands over its secrets to a vastly developed and commercially inspired technology, and the latter, even less restrained by a supreme culture saving principle, with the means of science creates all the instruments of power demanded from it by the organization of Might.”
—Johan Huizinga (1872–1945)
“Everything is becoming science fiction. From the margins of an almost invisible literature has sprung the intact reality of the 20th century.”
