Direct Piezoelectric Effect

Famous quotes containing the words direct and/or effect:

    A temple, you know, was anciently “an open place without a roof,” whose walls served merely to shut out the world and direct the mind toward heaven; but a modern meeting-house shuts out the heavens, while it crowds the world into still closer quarters.
    Henry David Thoreau (1817–1862)

    The second [of Zeno’s arguments about motion] is the one called “Achilles.” This is to the effect that the slowest as it runs will never be caught by the quickest. For the pursuer must first reach the point from which the pursued departed, so that the slower must always be some distance in front.
    Zeno Of Elea (c. 490–430 B.C.)
