Pressure Waves

Famous quotes containing the words pressure and/or waves:

    He who is of a calm and happy nature will hardly feel the pressure of age, but to him who is of an opposite disposition youth and age are equally a burden.
    Plato (c. 427–347 B.C.)

    You waves, though you dance by my feet like children at play,
    Though you glow and you glance, though you purr and you dart;
    In the Junes that were warmer than these are, the waves were more gay,
    When I was a boy with never a crack in my heart.
    William Butler Yeats (1865–1939)
