Famous quotes containing the words video, elementary and/or stream:

    These people figured video was the Lord’s preferred means of communicating, the screen itself a kind of perpetually burning bush. “He’s in the de-tails,” Sublett had said once. “You gotta watch for Him close.”
    William Gibson (b. 1948)

    As if paralyzed by the national fear of ideas, the democratic distrust of whatever strikes beneath the prevailing platitudes, it evades all resolute and honest dealing with what, after all, must be every healthy literature’s elementary materials.
    —H.L. (Henry Lewis)

    Thou stately stream that with the swelling tide
    ‘Gainst London walls incessantly dost beat,
    Thou Thames, I say, where barge and boat doth ride,
    And snow-white swans do fish for needful meat:
    George Turberville (1821–1873)
