Famous quotes containing the words discrete, rings and/or fields:

    “The mastery of one’s phonemes may be compared to the violinist’s mastery of fingering. The violin string lends itself to a continuous gradation of tones, but the musician learns the discrete intervals at which to stop the string in order to play the conventional notes. We sound our phonemes like poor violinists, approximating each time to a fancied norm, and we receive our neighbor’s renderings indulgently, mentally rectifying the more glaring inaccuracies.”
    —W.V. Quine (b. 1908)

    “The next time the novelist rings the bell I will not stir though the meeting-house burn down.”
    —Henry David Thoreau (1817–1862)

    “a child’s

    Through the parables
    Of sunlight
    And the legends of the green chapels

    And the twice-told fields of infancy”
    —Dylan Thomas (1914–1953)
