Famous quotes containing the word engine:

    “Industrial man—a sentient reciprocating engine having a fluctuating output, coupled to an iron wheel revolving with uniform velocity. And then we wonder why this should be the golden age of revolution and mental derangement.”
    —Aldous Huxley (1894–1963)
