    • constant Specifically In natural history, not subject to variation; not varying in number, form, color, appearance, etc., in the species or group; always present: as, the middle stria is constant, though the lateral ones are often absent; the reniform spot is constant, but the other markings are subject to variation.

    • n constant Specifically— In mathematics, a quantity which is assumed to be invariable throughout a given discussion; in the differential calculus, a quantity whose value remains fixed while others vary continuously. Although the constants do not vary by the variation of those quantities that are at first considered as variables, some or all of them may be conceived to vary in a second kind of change, called the variation of constants. A quantity which upon one supposition would remain constant becomes variable by the introduction of another supposition. Thus, taking into account the earth's attraction only, the longitude of the moon's node is constant, but by the attraction of the sun and planets its place is slowly changed. In this case one of the constants is said to vary. In algebra the unknown quantities are considered as variables, the known quantities and coefficients as constants.
    • n constant In physics, a numerical quantity, fixed under uniform conditions, expressing the value of one of the physical properties of a certain substance. Thus, the physical constants of ice are the values of its specific gravity, melting-point, coefficient of expansion, index of refraction, electrical conductivity, etc. Similarly, in the case of a physical instrument a constant is a fixed value depending upon its dimensions, etc. Thus, the constant of a tangent galvanometer is the radius of its coil divided by the number of coils into 6.28318+.
