anisotropy
anisotropy A characteristic of a substance or body in which physical properties are different in different directions. In astronomy, the temperature of the cosmic microwave background is observed to be anisotropic on a large angular scale as a result of the Sun's motion through space (dipole anisotropy), and on a small scale as a result of fluctuations in the density of the early Universe. See also Isotropy.
