Phase Change Materials

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

    “It no longer makes sense to speak of “feeding problems” or “sleep problems” or “negative behavior” is if they were distinct categories, but to speak of “problems of development” and to search for the meaning of feeding and sleep disturbances or behavior disorders in the developmental phase which has produced them.”
    —Selma H. Fraiberg (20th century)

    “Thus change the forms of being. Thus arise
    Races of living things, glorious in strength,
    And perish, as the quickening breath of God
    Fills them, or is withdrawn.”
    —William Cullen Bryant (1794–1878)

    “The competent leader of men cares little for the niceties of other peoples’ characters: he cares much—everything—for the exterior uses to which they may be put.... These are men to be moved. How should he move them? He supplies the power; others simply the materials on which that power operates.”
    —Woodrow Wilson (1856–1924)
