  statistical mechanics, quantitative study of systems consisting of a large number of interacting elements, such as the atoms or molecules of a solid, liquid, or gas, or the individual quanta of light (see photon) making up electromagnetic radiation. 
  MaxwellBoltzmann statistics apply to systems of classical particles, such as the atmosphere, in which considerations from the quantum theory are small enough that they may be ignored. 
  Statistical mechanics has also yielded deep insights in the understanding of magnetism, phase transitions, and superconductivity.
