## Objectives

When we seek to describe the electrical, magnetic, optical or thermal behaviour of solids, taking into account the large number of atoms per unit volume, it is not possible to carry out a precise analysis based on the behaviour of each atom.Solid state physics makes it possible to construct models which, when experimentally verified, may be considered as representative.

The formalism constructed to this end has numerous applications. Examples in diverse fields and which sometimes appear to be far removed from solid state physics will be given.
