Boundary Layer Separation

Famous quotes containing the words boundary, layer and/or separation:

    “The totality of our so-called knowledge or beliefs, from the most casual matters of geography and history to the profoundest laws of atomic physics or even of pure mathematics and logic, is a man-made fabric which impinges on experience only along the edges. Or, to change the figure, total science is like a field of force whose boundary conditions are experience.”
    —Willard Van Orman Quine (b. 1908)

    “After a few months’ acquaintance with European “coffee,” one’s mind weakens, and his faith with it, and he begins to wonder if the rich beverage of home, with its clotted layer of yellow cream on top of it, is not a mere dream after all, and a thing which never existed.”
    —Mark Twain [Samuel Langhorne Clemens] (1835–1910)

    “The scholar was not raised by the sacred thoughts amongst which he dwelt, but used them to selfish ends. He was a profane person, and became a showman, turning his gifts to marketable use, and not to his own sustenance and growth. It was found that the intellect could be independently developed, that is, in separation from the man, as any single organ can be invigorated, and the result was monstrous.”
    —Ralph Waldo Emerson (1803–1882)
