Famous quotes containing the words numbers and/or abundant:

    I’m not even thinking straight any more. Numbers buzz in my head like wasps.
    Kurt Neumann (1906–1958)

    It was a flourishing tropic he required
    For his refreshment, an abundant zone,
    Prickly and obdurate, dense, harmonious,
    Yet with a harmony not rarefied
    Nor fined for the inhibited instruments
    Of over-civil stops.
    Wallace Stevens (1879–1955)
