A Visit of Granular Matter
Granular materials have been used for ages in many domains of technology and have served as models in describing the differents states of matter for many centuries. However, their study knows presently new spectacular developments thanks to the use of methods and concepts of statistical physics introduced to describe the disorder of matter. We describe a few properties and experiments wich often display surprising behaviors and begin to be understood. This note is a reduced version of a recently written book “du sac de billes au tas de sable”  which deals with the coordinated activity on the subject , in particular in France.
