Famous quotes containing the word size:

    “Men of genius are not quick judges of character. Deep thinking and high imagining blunt that trivial instinct by which you and I size people up.”
    —Max Beerbohm (1872–1956)

    “O hideous little bat, the size of snot,
    With polyhedral eye and shabby clothes,”
    —Karl Shapiro (b. 1913)

    “In mathematics he was greater
    Than Tycho Brahe, or Erra Pater:
    For he, by geometric scale,
    Could take the size of pots of ale;
    Resolve, by sines and tangents straight,
    If bread and butter wanted weight;
    And wisely tell what hour o’ th’ day
    The clock doth strike, by algebra.”
    —Samuel Butler (1612–1680)
