Famous quotes containing the words radiation and/or forces:

    There are no accidents, only nature throwing her weight around. Even the bomb merely releases energy that nature has put there. Nuclear war would be just a spark in the grandeur of space. Nor can radiation “alter” nature: she will absorb it all. After the bomb, nature will pick up the cards we have spilled, shuffle them, and begin her game again.
    Camille Paglia (b. 1947)

    The poorest man may in his cottage bid defiance to all the forces of the Crown. It may be frail—its roof may shake—the wind may blow through it—the storm may enter—the rain may enter—but the King of England cannot enter!—all his forces dare not cross the threshold of the ruined tenement!
    William Pitt, The Elder, Lord Chatham (1708–1778)
