Famous quotes containing the words keys and/or function:

    without luggage or defenses,
    giving up my car keys and my cash,
    keeping only a pack of Salem cigarettes
    the way a child holds on to a toy.
    I signed myself in where a stranger
    puts the inked-in X’s
    Anne Sexton (1928–1974)

    The information links are like nerves that pervade and help to animate the human organism. The sensors and monitors are analogous to the human senses that put us in touch with the world. Data bases correspond to memory; the information processors perform the function of human reasoning and comprehension. Once the postmodern infrastructure is reasonably integrated, it will greatly exceed human intelligence in reach, acuity, capacity, and precision.
