have you ever seen someone juggle and wondered how they do it? or, are you able to juggle but have wondered how the process might be described mathematically? in this talk, i will introduce the concept of a juggling sequence (and what jugglers call “siteswap notation”) and how juggling sequences can be used to describe simple juggling patterns. i will also address some of the mathematical questions related to juggling sequences, such as “which periodic sequences are jugglable?” in addition, i will illustrate some simple juggling patterns by juggling them (when i'm not picking up the balls off the floor) and i'll have a juggling animator program available to illustrate patterns not accessible to my juggling skills. \vskip .1in \noindent refreshments will be provided! \vskip 2in
