121Force-free magnetic field — A force free magnetic field is a type of field which arises as a special case from the magnetostatic equation in plasmas. This special case arises when the plasma pressure is so small, relative to the magnetic pressure, that the plasma pressure… …
122Mixing patterns — refer to systematic tendencies of one type of nodes in a network to connect to another type. For instance, nodes might tend to link to others that are very similar or very different. This feature is common in many social networks, although it… …

124No hair theorem — The no hair theorem in astrophysics postulates that all black hole solutions of the Einstein Maxwell equations of gravitation and electromagnetism in general relativity can be completely characterized by only three externally observable classical …
125Four-vector — In relativity, a four vector is a vector in a four dimensional real vector space, called Minkowski space. It differs from a vector in that it can be transformed by Lorentz transformations. The usage of the four vector name tacitly assumes that… …
