Zero \Ze"ro\, n.; pl. {Zeros}or {Zeroes}. [F. z[82]ro, from Ar. [cced]afrun, [cced]ifrun, empty, a cipher. Cf. {Cipher}.] 1. (Arith.) A cipher; nothing; naught. 2. The point from which the graduation of a scale, as of a thermometer, commences. Note: Zero in the Centigrade, or Celsius thermometer, and in the R[82]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[f8] on the Fahrenheit scale. See Illust. of {Thermometer}. 3. Fig.: The lowest point; the point of exhaustion; as, his patience had nearly reached zero. {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. |
