Physical Water Scarcity

Famous quotes containing the words physical and/or water:

    Theory may be deliberate, as in a chapter on chemistry, or it may be second nature, as in the immemorial doctrine of ordinary enduring middle-sized physical objects.
    Willard Van Orman Quine (b. 1908)

    We were uncertain whether the water floated the land, or the land held the water in its bosom. It was such a season, in short, as that in which one of our Concord poets sailed on its stream, and sung its quiet glories.
    Henry David Thoreau (1817–1862)
