My equation-oriented book, Physics of Societal Issues: Calculations on National Security, Environment and Energy (PSI) is now available as a paperback for $25 (total cost), which is 15% of the $159 hardback (without shipping and handling). Go to www.springer.com/mycopy when on-campus to purchase PSI. Most universities have a contract with Springer for this my-copy bargain. PSI is now in its second printing, and in the distant future there will be a 2nd edition. It was reviewed in American Journal of Physics [AJP 77, 479 (2009)] and Physics and Society [July 2007, pp. 14-15].
