... Complex systems admit many descriptions (ways of looking at the system) each of which is only partially true. Each way of looking at a complex system requires its own description, its own mode of analysis ... the principles of the thermodynamics of "closed" systems studied by physicists do not apply. Unlike closed systems (in which a state of equilibrium is established...
