The May issue showcases diverse features of the mathematical life. John Ewing, former executive director of the AMS and now president of Math for America, tells us of the dangers of value-added modeling. Michael Saclolo writes of a mathematical analysis of the poetry of medieval troubadours. Catherine Bénéteau and Patrick Van Fleet explain how wavelets can be used to augment undergraduate mathematics education. Finally, we share memories of noted mathematician Leon Ehrenpreis.
