Modulus is the
diminutive
A diminutive is a root word that has been modified to convey a slighter degree of its root meaning, either to convey the smallness of the object or quality named, or to convey a sense of intimacy or endearment. A (abbreviated ) is a word-formati ...
from the Latin word ''modus'' meaning measure or manner. It, or its plural moduli, may refer to the following:
Physics, engineering and computing
*
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
*
Modulo operation (
a % b,
mod(a, b), etc.), in both math and programming languages; results in remainder of a division
* Casting modulus used in
Chvorinov's rule
Chvorinov's rule is an applied physics relationship first expressed by Czech engineer Nicolas Chvorinov in 1940, that relates the solidification time for a simple casting to the volume and surface area of the casting. In simple terms the rule est ...

Modulus (modular arithmetic)
In mathematics, modular arithmetic is a system of arithmetic for integers, where numbers "wrap around" when reaching a certain value, called the modulus. The modern approach to modular arithmetic was developed by Carl Friedrich Gauss in his book ...

* Modulus, the
absolute value
In mathematics, the absolute value or modulus of a real number x, is the non-negative value without regard to its sign. Namely, , x, =x if is a positive number, and , x, =-x if x is negative (in which case negating x makes -x positive), an ...

Moduli space
In mathematics, in particular algebraic geometry, a moduli space is a geometric space (usually a scheme or an algebraic stack) whose points represent algebro-geometric objects of some fixed kind, or isomorphism classes of such objects. Such spac ...

Conformal modulus In the mathematical theory of conformal and quasiconformal mappings, the extremal length of a collection of curves \Gamma is a measure of the size of \Gamma that is invariant under conformal mappings. More specifically, suppose that D is an open se ...
