Water Pressure Difference

Famous quotes containing the words water, pressure and/or difference:

    By constant dripping, water hollows stone,
    A signet-ring from use alone grows thin,
    And the curved plowshare by soft earth is worn.
    Ovid (Publius Ovidius Naso)

    Destiny is an absolutely definite and inexorable ruler. Physical ability and moral determination count for nothing. It is impossible to perform the simplest act when the gods say “no.” I have no idea how they bring pressure to bear on such occasions; I only know that it is irresistible.
    Aleister Crowley (1875–1947)

    I find it a great and fatal difference whether I court the Muse, or the Muse courts me. That is the ugly disparity between age and youth.
    Ralph Waldo Emerson (1803–1882)
