# Statistical Physics

Many physical systems contain a large number of particles which may have complicated interactions. The use of statistical methods to describe such apparently intractable problems has been one of the greatest triumphs of theoretical physics. While classical statistical mechanics has explained both the foundations and the intricate consequences of thermodynamics, in recent years the emphasis has shifted towards applying probabilistic approaches to almost any type of complex phenomenon, extending from physics and chemistry into biology, social sciences and economics.

The Open University organises an annual Open Statistical Physics meeting, usually held in late March.
