Famous quotes containing the words engineering and/or science:

    Mining today is an affair of mathematics, of finance, of the latest in engineering skill. Cautious men behind polished desks in San Francisco figure out in advance the amount of metal to a cubic yard, the number of yards washed a day, the cost of each operation. They have no need of grubstakes.
    Merle Colby, U.S. public relief program (1935-1943)

    You are all fundamentalists with a top dressing of science. That is why you are the stupidest of conservatives and reactionists in politics and the most bigoted of obstructionists in science itself. When it comes to getting a move on you are all of the same opinion: stop it, flog it, hang it, dynamite it, stamp it out.
    George Bernard Shaw (1856–1950)
