The September issue features many exciting and diverse articles. One, by David Borthwick and Skip Garibaldi, is on the group E_8 and its importance for physics. Another, by Fields Medalist S.-T. Yau and Steve Nadis, is about string theory and the shape of the universe. David Zitarelli writes about the 1904 Mathematics Congress in St. Louis. A number of authors share their memories of Gerhard Hochschild. Keith Stroyan, in his education column, discusses why so many students take calculus. Peter Olver contributes the first publication column on journals in flux. Susan Hezlet and others report on the workshop at MSRI on the changing nature of mathematics journals. And Eric Friedlander (president of the AMS) and Frank Morgan debate the merits of the Fellows Program.--Steven G. Krantz, Editor
