Hi, Further to my previous messages on Ball's book, members of the list in the American continent won't have access to it before June, so maybe it's best to let Ball speak. Here's a selection of his work on the topic that predates the book: Ball, P.,"The physics of society", Nature 415, 371 (2002) (Attached) Utopia Theory http://physicsweb.org/article/world/16/10/7 Ball, P. "The physical modelling of society: a historical perspective" Physica A 314 (2002) 1 - 14 Available at: http://www.whitebottom.com/philipball/ps01_01.asp Rui
