Famous quotes containing the words structure and, structure and/or properties:

    “With sixty staring me in the face, I have developed inflammation of the sentence structure and definite hardening of the paragraphs.”
    —James Thurber (1894–1961)

    “The structure was designed by an old sea captain who believed that the world would end in a flood. He built a home in the traditional shape of the Ark, inverted, with the roof forming the hull of the proposed vessel. The builder expected that the deluge would cause the house to topple and then reverse itself, floating away on its roof until it should land on some new Ararat.”
    —For the State of New Jersey, U.S. public relief program (1935-1943)

    “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)
