Phase Change Materials

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

    “This is certainly not the place for a discourse about what festivals are for. Discussions on this theme were plentiful during that phase of preparation and on the whole were fruitless. My experience is that discussion is fruitless. What sets forth and demonstrates is the sight of events in action, is living through these events and understanding them.”
    —Doris Lessing (b. 1919)

    “In the great and deep qualities of mind, heart, and soul, there is no change. Homer and Solomon speak to the same nature in man that is reached by Shakespeare and Lincoln. but in the accidents, the surroundings, the change is vast. All things now are mobile—movable.”
    —Rutherford Birchard Hayes (1822–1893)

    “Though the hen should sit all day, she could lay only one egg, and, besides, would not have picked up materials for another.”
    —Henry David Thoreau (1817–1862)
