Surface Integral Vanishes

Famous quotes containing the words surface, integral and/or vanishes:

    White Pond and Walden are great crystals on the surface of the earth, Lakes of Light.... They are too pure to have a market value; they contain no muck. How much more beautiful than our lives, how much more transparent than our characters are they! We never learned meanness of them.
    Henry David Thoreau (1817–1862)

    An island always pleases my imagination, even the smallest, as a small continent and integral portion of the globe. I have a fancy for building my hut on one. Even a bare, grassy isle, which I can see entirely over at a glance, has some undefined and mysterious charm for me.
    Henry David Thoreau (1817–1862)

    The only way therefore to try a Piece of Wit, is to translate it into a different Language: If it bears the Test you may pronounce it true; but if it vanishes in the Experiment you may conclude it to have been a Punn.
    Joseph Addison (1672–1719)
