Next week is the biennial Topology Students Workshop, organized by Dan Margalit since 2012. As part of this event, there will be a public lecture on Wednesday, July 27, 4-5 pm, in the Student Success Center. The title of the talk is *Juggling Numbers, Algebra, and Topology*. Refreshments will be served at 3:30.

The talk is appropriate for people of all ages and backgrounds.

One goal of mathematics is to describe the patterns in the world, from weather to population growth to disease transmission. We will use mathematics to describe juggling patterns, count the different kinds of patterns, and create new patterns. We will make surprising connections to group theory, topology, combinatorics, and number theory. This talk is meant to be accessible to curious people of all ages and backgrounds.
