isotropy

n. isotropism; uniformity of properties and characteristics along all axes (Physics); state of having no predefined axes (Zoology)

Isotropy (the opposite of anisotropy) is the property of being independent of direction. Isotropic radiation has the same intensity regardless of the direction of measurement, and an isotropic field exerts the same action regardless of how the test particle is oriented.Within mathematics, Isotropy has a few different meanings:Isotropic manifolds: Some manifolds are isotropic, meaning that the geometry on the manifold is the same regardless of direction. A similar concept is homogeneity. A manifold can be homogeneous without being isotropic. But if it is inhomogeneous, it is necessarily anisotropic.Isotropic quadratic form: A quadratic form q is said to be isotropic if there is a non-zero vector v such that q(v)=0.Isotropic coordinates on an Isotropic chart for Lorentzian manifolds.
