Modulus is the diminutive from the Latin word modus meaning measure or manner. It, or its plural moduli, may refer to the following:
Physics and engineering Moduli (physics), scalar fields for which the potential energy function has continuous families of global minima The measurement of standard pitch in the teeth of a rotating gear Bulk modulus, a measure of compression resistance Elastic modulus, a measure of stiffness Shear modulus, a measure of elastic stiffness Young's modulus, a specific elastic modulus Casting modulus used in Chvorinov's rule.
Computing Modulus (digital counter), the number of states in a counter's count sequence Modulo operation (a % b, mod(a, b), etc.), in both math and programming languages; results in remainder of a division
Mathematics Modulus, the absolute value of a real or complex number ( ) Modulus (modular arithmetic), base of modular arithmetic Similarly, the modulus of a Dirichlet character Moduli space, in mathematics a geometric space whose points represent algebro-geometric objects Conformal modulus, a measure of the size of a curve family Modulus of continuity, a function gauging the uniform continuity of a function Similarly, modulus of convergence Modulus (algebraic number theory), a formal product of places of a number field The modular function in the theory of Haar measure, often called simply the modulus
Other uses Modulus (gastropod) a genus of small sea snails Modulus Guitars, musical instrument manufacturer Modulus robot, a household robot
