Famous quotes containing the words specific, weight and/or air:

    The permanence of all books is fixed by no effort friendly or hostile, but by their own specific gravity, or the intrinsic importance of their contents to the constant mind of man.
    Ralph Waldo Emerson (1803–1882)

    You will trail across the rocks
    and wash them with your salt,
    you will curl between sand-hills
    you will thunder along the cliff
    break retreat get fresh strength
    gather and pour weight upon the beach.
    Hilda Doolittle (1886–1961)

    At length, having come up fifty rods off, he uttered one of those prolonged howls, as if calling on the god of loons to aid him, and immediately there came a wind from the east and rippled the surface, and filled the whole air with misty rain, and I was impressed as if it were the prayer of the loon answered, and his god was angry with me; and so I left him disappearing far away on the tumultuous surface.
    Henry David Thoreau (1817–1862)
