Path Integral Formulation/concrete Formulation

Famous quotes containing the words path, integral, formulation and/or concrete:

    The broken ridge of the hills
    was the line of a lover’s shoulder,
    his arm-turn, the path to the hills,
    the sudden leap and swift thunder
    of mountain boulders, his laugh.
    Hilda Doolittle (1886–1961)

    Painting myself for others, I have painted my inward self with colors clearer than my original ones. I have no more made my book than my book has made me—a book consubstantial with its author, concerned with my own self, an integral part of my life; not concerned with some third-hand, extraneous purpose, like all other books.
    Michel de Montaigne (1533–1592)

    You do not mean by mystery what a Catholic does. You mean an interesting uncertainty: the uncertainty ceasing interest ceases also.... But a Catholic by mystery means an incomprehensible certainty: without certainty, without formulation there is no interest;... the clearer the formulation the greater the interest.
    Gerard Manley Hopkins (1844–1889)

    “The city’s grotesque iron skeletons
    Would knock their drunken penthouse heads together
    And cake their concrete dirt off in the streets.”
    Robert Frost (1874–1963)
