The November issue features several articles bearing on math education. These include a *Doceamus* on moving from the routine to the nonroutine in problem solving, a piece on the structure of U.S. elementary school mathematics, and an article on what secondary preservice math teachers need to know. In a historical direction, we have an article about the role of Cauchy's mean value theorem in the history of analytic rigor. Finally, there is an unusual article about the application of mathematical principles to the negotiation of peace in the Middle East. --Steven G. Krantz, Editor
