Famous quotes containing the words structure and/or properties:

    “It is difficult even to choose the adjective
    For this blank cold, this sadness without cause.
    The great structure has become a minor house.
    No turban walks across the lessened floors.
    The greenhouse never so badly needed paint.”
    —Wallace Stevens (1879–1955)

    “A drop of water has the properties of the sea, but cannot exhibit a storm. There is beauty of a concert, as well as of a flute; strength of a host, as well as of a hero.”
    —Ralph Waldo Emerson (1803–1882)
