Join us on Tuesday, February 28th at Noon in Tome 115 for our next Math/CS Chat.  Jim Wiseman, Agnes Scott College, will present "Computation and Chaos".  Free pizza & everyone welcome.

Abstract: A dynamical system is one that evolves over time according to fixed rules - for example, the motion of the planets, the populations of competing species of animals, or the formation of traffic jams.  Simple rules can often lead to chaotic behavior.  It's natural to try to use computers to understand these systems, but unfortunately even the tinest numerical error renders the results useless for pure mathematics, which demands exact answers, not approximations.  The problems are especially bad when we try to study the long-term behavior of chaotic dynamical systems, since small errors can quickly accumulate into big ones.  We'll look at these problems, and at ways in which we can overcome them to use numerical approximation to prove mathematically rigorous results.

Benjamin J. Galluzzo, Assistant Professor of Mathematics at Shippensburg University, will present "Water, water everywhere, but is it safe to drink?" on Tuesday, February 7th at Noon in Tome 115.  Free pizza, everyone welcome!

Abstract: In Pennsylvania and throughout North America, clean potable water is in abundance, or is it?  Interestingly, answers to this question are formulated using remarkably accessible mathematics.  In this talk, we will introduce basic hydrogeologic principles and use algebraic manipulation - as well as a little calculus - to develop a working subsurface fluid flow model.  The talk will conclude with a brief discussion on the direction of current research in the discipline.
