Coulomb's inverse square law was first published more than two centuries ago, but is, of course, still of wide use in plasma researches, in which the whole mighty apparatus of theoretical physics is engaged. Sophisticated methods have been developed to describe the plasma under various external conditions, ranging from classical mechanics to quantum and relativistic statistics. This book exploits another brilliant idea when Coulombs' law is formally replaced by some fictitious pseudopotential and just one single approach provides a wonderful opportunity to correctly predict and firmly grasp the physical properties of many types of plasmas, encountered in nature and laboratory. It is entirely based on the renormalization procedure of interparticle interactions that relies on so elementary and attractive arguments, everyone is surely going to like.
