Direct Piezoelectric Effect

Famous quotes containing the words direct and/or effect:

    Of course it is of no use to direct our steps to the woods, if they do not carry us thither. I am alarmed when it happens that I have walked a mile into the woods bodily, without getting there in spirit.... What business have I in the woods, if I am thinking of something out of the woods?
    Henry David Thoreau (1817–1862)

    Before the effect one believes in different causes than one does after the effect.
    Friedrich Nietzsche (1844–1900)
