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)

    The change of Philomel, by the barbarous king
    So rudely forced; yet there the nightingale
    Filled all the desert with inviolable voice
    And still she cried, and still the world pursues,
    “Jug Jug” to dirty ears.
    —T.S. (Thomas Stearns)

    If our entertainment culture seems debased and unsatisfying, the hope is that our children will create something of greater worth. But it is as if we expect them to create out of nothing, like God, for the encouragement of creativity is in the popular mind, opposed to instruction. There is little sense that creativity must grow out of tradition, even when it is critical of that tradition, and children are scarcely being given the materials on which their creativity could work
    C. John Sommerville (20th century)
