Dipole anisotropy typically refers to a directional dependence in a physical quantity, often observed in the context of cosmic phenomena or fields. In cosmology, for example, dipole anisotropy is often discussed in relation to the Cosmic Microwave Background (CMB) radiation. In this context, the CMB is the afterglow of the Big Bang, and while it is generally uniform, it does exhibit slight variations in temperature that can be analyzed.
