We are pleased to announce the winners of the Great Application Contest. First prize is awarded to Dr. Jason Schattman, for his entry Can a Square Roll?, an exploration of the "Renaissance Man of calculus problems", the square wheel problem. The runner-up is Prof. Mario Lemelin, for his Pré-test en Mathématique, a Maple-based questionnaire that lets beginning differential calculus students test their secondary school mathematics comprehension. These and many other Maple applications can of course be viewed on the Maple Application Center. Congratulations to both!
