Heat Exchange Surface

Famous quotes containing the words heat, exchange and/or surface:

    Even if you find yourself in a heated exchange with your toddler, it is better for your child to feel the heat rather than for him to feel you withdraw emotionally.... Active and emotional involvement between parent and child helps the child make the limits a part of himself.
    Stanley I. Greenspan (20th century)

    So long as the law considers all these human beings, with beating hearts and living affections, only as so many things belonging to the master—so long as the failure, or misfortune, or imprudence, or death of the kindest owner, may cause them any day to exchange a life of kind protection and indulgence for one of hopeless misery and toil—so long it is impossible to make anything beautiful or desirable in the best-regulated administration of slavery.
    Harriet Beecher Stowe (1811–1896)

    We say justly that the weak person is flat, for, like all flat substances, he does not stand in the direction of his strength, that is, on his edge, but affords a convenient surface to put upon. He slides all the way through life.... But the brave man is a perfect sphere, which cannot fall on its flat side and is equally strong every way.
    Henry David Thoreau (1817–1862)
