Quadratic Difference Tones

Famous quotes containing the words difference and/or tones:

    It is so wonderful to our neurologists that a man can see without his eyes, that it does not occur to them that is just as wonderful that he should see with them; and that is ever the difference between the wise and the unwise: the latter wonders at what is unusual, the wise man wonders at the usual.
    Ralph Waldo Emerson (1803–1882)

    There sighs, lamentations and loud wailings resounded through the starless air, so that at first it made me weep; strange tongues, horrible language, words of pain, tones of anger, voices loud and hoarse, and with these the sound of hands, made a tumult which is whirling through that air forever dark, as sand eddies in a whirlwind.
    Dante Alighieri (1265–1321)
