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)

    News reports don’t change the world. Only facts change it, and those have already happened when we get the news.
    Friedrich Dürrenmatt (1921–1990)

    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)
