Phase Change Materials

Famous quotes containing the words phase, change and/or materials:

    The problem of the twentieth century is the problem of the color-line—the relation of the darker to the lighter races of men in Asia and Africa, in America and the islands of the sea. It was a phase of this problem that caused the Civil War.
    —W.E.B. (William Edward Burghardt)

    It was palpable, all that wanting: Mother wanting something more, Dad wanting something more, everyone wanting something more. This wasn’t going to do for us fifties girls; we were going to have to change the equation even if it meant . . . abstaining from motherhood, because clearly that was where Mother got caught.
    Anne Taylor Fleming (20th century)

    In how few words, for instance, the Greeks would have told the story of Abelard and Heloise, making but a sentence of our classical dictionary.... We moderns, on the other hand, collect only the raw materials of biography and history, “memoirs to serve for a history,” which is but materials to serve for a mythology.
    Henry David Thoreau (1817–1862)
