    • n zero In function-theory, a value of x which makes the function vanish.
    • n zero In psychophysics, the temperature at which a thermal stimulus fails to arouse a sensation either of warmth or of cold in the cutaneous organs; the indifference-point of thermal stimulation.
    • n zero Cipher; the figure 0, which stands for naught in the Arabic notation for numbers.
    • n zero The defect of all quantity considered as quantity; the origin of measurement stated as at a distance from itself; nothing, quantitatively regarded. Upon a thermometer or any similar scale zero is the line from which all the divisions are measured in the positive and negative directions. Upon the centigrade and Réaumur's thermometers, it is the point at which the mercury stands when the thermometer is plunged into a mass of melting ice coarsely pulverized, from which some makers allow the water to drain off, but it is better not to do so. For some years after a thermometer is made the zero is said to rise—that is, the melting-point of ice stands higher and higher upon the scale. Upon the Fahrenheit thermometer the distance on the glass stem between the melting-point of ice and the temperature of steam at one English atmosphere of tension is divided into 180 degrees, and 32 such degrees below the melting-point of ice is marked as zero.
    • n zero Hence—3. Figuratively, the bottom of the scale; the lowest point or ebb; a state of nullity or inanition.
