Objective :

Deduct properties from macroscopic scaled systems with laws that rule elementary matter at microscopic scales. 

 

Program and Content :

Statistical physics is a part from Physics that studies the global behavior of systems made of a lot of particles, with the aim to establish a link between macroscopical physics and microscopical laws that rule the elementary constituents of these macroscopical systems. It was initially developed to explain Thermodynamics, but then grew up to model complex systems, in-which particles can be concrete objects (electron, atoms, molecules, grains of sand) but also more abstract objects (economical agents, bits of information). Hence statistical physics remains one of the pillar of modern physics. Crossing many areas, it is still facing major scientific challenges with strong societal issues. It is then a key discipline for the engineers of the next century.
