Statistical physics is one field of physics, challenging to reconstruct our world from its elements. This field started from a theory to connect thermodynamics and molecular motion and statistical description of a state based on molecular-level equations of motion, virtual mathematics of causality. Thermodynamics entropy is reformulated with information measure, and information theory hatched on it. Theories on phases and transitions are a starting point of emergence phenomena, optimization, and intelligent systems. Now a day, methodologies of statistical physics have been applied successfully to non-physical objects like social systems, for example, traffic flow, money flow and socialrelationships.
