  Zero \Ze"ro\, n.; pl. Zerosor Zeroes. [F. z['e]ro, from Ar.
     [,c]afrun, [,c]ifrun, empty, a cipher. Cf. Cipher.]
     [1913 Webster]
     1. (Arith.) A cipher; nothing; naught.
        [1913 Webster]
  
     2. The point from which the graduation of a scale, as of a
        thermometer, commences.
        [1913 Webster]
  
     Note: Zero in the Centigrade, or Celsius thermometer, and in
           the R['e]aumur thermometer, is at the point at which
           water congeals. The zero of the Fahrenheit thermometer
           is fixed at the point at which the mercury stands when
           immersed in a mixture of snow and common salt. In
           Wedgwood's pyrometer, the zero corresponds with
           1077[deg] on the Fahrenheit scale. See Illust. of
           Thermometer.
           [1913 Webster]
  
     3. Fig.: The lowest point; the point of exhaustion; as, his
        patience had nearly reached zero.
        [1913 Webster]
  
     Absolute zero. See under Absolute.
  
     Zero method (Physics), a method of comparing, or measuring,
        forces, electric currents, etc., by so opposing them that
        the pointer of an indicating apparatus, or the needle of a
        galvanometer, remains at, or is brought to, zero, as
        contrasted with methods in which the deflection is
        observed directly; -- called also null method.
  
     Zero point, the point indicating zero, or the commencement
        of a scale or reckoning.

  zero point
       n : the quantity that registers a reading of zero on a scale
           [syn: zero]

  zero point
     n.
     (lb en military) The location of the center of a burst of a nuclear
  weapon at the instant of detonation. The zero point may be in the air,
  or on or beneath the surface of land or water, depending upon the type
  of burst, and it is thus to be distinguished from ground zero.
