Book excerpt: Excerpt from Microscopic and Macroscopic Models in Plasma Physics One is frequently presented with the alternative of studying a physical problem with a detailed and difficult microscopic model or a less cluttered and simpler, but not so clearly applicable, macroscopic model. The microsc0pic detail can be not only burdensome but, on occasion, even irrelevant; we recall from statistical mechanics the existence of macroscopic laws that are almost independent of particular molecular properties or motions. For classical fluids, we have recourse to experiment and to the (quite difficult and easily misinterpreted) theoretical derivation of macroscopic laws. For a plasma, unfortunately, experimental knowledge is not yet comprehensive enough to provide any significant degree of synthesis. Thus theoretical derivation of macroscopic laws (at least as difficult and as risky as for an ordinary gas) is our only alternative at present.
