Phase Change Materials

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

    I had let preadolescence creep up on me without paying much attention—and I seriously underestimated this insidious phase of child development. You hear about it, but you’re not a true believer until it jumps out at you in the shape of your own, until recently quite companionable child.
    Susan Ferraro (20th century)

    Most men would feel shame if caught preparing with their own hands precisely such a dinner, whether of animal or vegetable food, as is every day prepared for them by others. Yet till this is otherwise we are not civilized, and, if gentlemen and ladies, are not true men and women. This certainly suggests what change is to be made.
    Henry David Thoreau (1817–1862)

    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)
