Direct Piezoelectric Effect

Famous quotes containing the words direct and/or effect:

    Irony, forsooth! Guard yourself, Engineer, from the sort of irony that thrives up here; guard yourself altogether from taking on their mental attitude! Where irony is not a direct and classic device of oratory, not for a moment equivocal to a healthy mind, it makes for depravity, it becomes a drawback to civilization, an unclean traffic with the forces of reaction, vice and materialism.
    Thomas Mann (1875–1955)

    At the heart of the educational process lies the child. No advances in policy, no acquisition of new equipment have their desired effect unless they are in harmony with the child, unless they are fundamentally acceptable to him.
    —Central Advisory Council for Education. Children and Their Primary Schools (Plowden Report)
