Optical Gradient Force

Famous quotes containing the words optical and/or force:

    The convent, which belongs to the West as it does to the East, to antiquity as it does to the present time, to Buddhism and Muhammadanism as it does to Christianity, is one of the optical devices whereby man gains a glimpse of infinity.
    Victor Hugo (1802–1885)

    The event combined with
    Beams leading up to it for the look of force adapted to the wiser
    Usages of age, but it’s both there
    And not there, like washing or sawdust in the sunlight,
    At the back of the mind, where we live now.
    John Ashbery (b. 1927)
