Causality (also referred to as causation[1] or cause and effect) is concerned with the study of how systems state of affairs change by means of agents called causes and produce new states called effects. The binding between former and latter states is called causality nexus. One or more concurring causes can produce effects that can be either final and stable or transient and unstable. In this case, the former effects become new causes activating sequential cascades (a -> b -> c -> ...) or exponential growing numbers of parallel chain reactions (as in nuclear fission). --
