Modulus

Modulus is the diminutive from the Latin word modus meaning measure or manner. It, or its plural moduli, may refer to any of 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
• Elastic modulus, a measure of stiffness
• Young's modulus, a specific elastic modulus
• The modulo operator (%, mod, etc.) of various programming languages

Mathematics

• 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
• Modular arithmetic, the modulus being the value at which numbers "wrap around"
• Similarly, the modulus of a Dirichlet character
• Modulus (algebraic number theory), a formal product of places of a number field
• The absolute value of a real or complex number ( |a | )
• 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
