Scaling and Root Planing/physical Principles

Famous quotes containing the words root, physical and/or principles:

    Black creeps from root to root,
    each leaf
    cuts another leaf on the grass,
    shadow seeks shadow,
    then both leaf
    and leaf-shadow are lost.
    Hilda Doolittle (1886–1961)

    For my part I do, qua lay physicist, believe in physical objects and not in Homer’s gods; and I consider it a scientific error to believe otherwise.
    Willard Van Orman Quine (b. 1908)

    I cannot consent that my mortal body shall be laid in a repository prepared for an Emperor or a King—my republican feelings and principles forbid it—the simplicity of our system of government forbids it.
    Andrew Jackson (1767–1845)
