102 Tom Salisbury acre! But, from a long life in physics, he can testify for the major role of organizations like the Fields Institute.” Pierre-Gilles de Gennes (Nobel Prize, Physics, 1991.) The following Fields story was told to me by Wendelin Werner. He and Greg Lawler were in an upstairs office at Fields, as participants at a 1999 conference (that year’s Seminar on Stochastic Processes), when they received an e-mail from Oded Schramm sharing a construction of a new conformally invariant random process, now called SLE. Those who know this subject will recognize that this means there is a Fields Institute chapter in the work that eventually led to Wendelin’s 2006 Fields medal. The infrastructure that supports thematic programs is also used in other ways, since Fields is a natural venue for faculty at multiple universities to come together to collaborate on projects. For example, during my time at Fields, statisticians from across Canada worked at developing the National Program for Complex Data Structures (NPCDS), a precursor to today’s Canadian Statistical Sciences Institute (CANSSI). The range of mathematics and statistics conferences and workshops organized through Fields is striking. Among the most unusual I can remember are two musical concerts we organized in the institute, whose audiences sat both in the atrium and above it, looking down. One of these focused on the mathematically constructed compositions of Iannis Xenakis. The other featured music composed by Donald Coxeter, including a string quartet in which Catherine Sulem and Niky Kamran performed. Mathematics Education The Fields Mathematics Education forum brings together mathematicians, teachers, and educators. In 2005 it helped
