Laplace's demon - A hypothetical all-knowing entity (later called "Laplace's Demon") who knows the precise location and momentum of every atom in the universe, and therefore could use Newton's laws to reveal the entire course of cosmic events, past and future. Based upon the philosophical proposition of causal determinism. (See also causality).
Maxwell's demon - A demon able to distinguish between fast and slow moving molecules. If this demon only let fast moving molecules through a trapdoor to a container, the temperature inside the container would increase without any work being applied. Such a scenario would violate the second law of thermodynamics.
