Psychology Speaker: How Culture influences Our Emotions
Speaker: Jeanne Tsai, Ph.D., Stanford University
Speaker: Matthew Wright, St. Olaf Assistant Professor of Mathematics
Abstract: If you watch a skilled juggler, you may see balls (or other objects) flying through the air in intricate patterns. What patterns are possible? Starting with a few basic axioms about juggling, we can use mathematics to describe all “jugglable” patterns. In this talk, I will explain how integer sequences can help us enumerate all such patterns. This talk will feature modular arithmetic, Möbius inversion, and – of course – live juggling.

MSCS Research Seminar: Continuity and chaos in discrete dynamical systems
Speaker: T. H. Steele, Professor, Weber State University, Ogden Utah
Abstract: In the latter part of the nineteenth century, there was a belief in the deterministic, clockwork precision of the universe. From this belief arose an interest in establishing the stability of the planetary motions in our solar system. Oscar II, King of Sweden and Norway, initiated a mathematical competition in 1887 to celebrate his sixtieth birthday in 1889. One of the problems, posed by Karl Weierstrass, dealt with this stability: ”Given a system of arbitrarily many mass points that attract each other according to Newton’s laws, assuming that no two points ever collide, give the coordinates of the individual points for all time….”
