Juggling: Theory and Practice (aka The Juggling Talk)Juggling has fascinated people for centuries. Seemingly oblivious to gravity, the skilled practitioner will keep several objects in the air at one time, and weave complex patterns that seem to defy analysis. In this talk we'll see a selection of the patterns and skills of juggling while at the same time developing a simple method of describing and annotating a class of juggling patterns. By using elementary mathematics these patterns can be classified, leading to a simple way to describe those patterns that are known already, and a technique for discovering new ones.
Bigger Than InfinityWe're used to thinking of "Infinity" as meaning "As big as you can get". In this talk we find that when we think carefully about "going on forever" we discover that there are different types of infinity, and, even more puzzling, and defying all expectation, different sizes of infinity. Prepare to have your mind blown. No knowledge is assumed, but generally given for 15+ as the ideas are deep, and so ages 1314 might struggle.
Getting lost in 1000 dimensionsSome people find it hard enough to navigate around in two dimensions, and have trouble thinking about moving around in three. In this talk we look at what dimensions are, how we work in them, and how some problems in the real world can best be thought of as going hillclimbing in 1000 dimensions (whatever that means!)
The Doodle TheoremStarting with a simple doodle, this talk goes via a classical problem from the 18th Century, touches on unexpected connections with modern social networks, and finishes with an unsolved problem with a million dollar bounty. This is a board talk, and it's best if the students have pen/pencil and paper to doodle on.
Patterns And PredictionsTalks about puzzles, patterns, and then finishes with finding unexpected patterns in juggling. This overlaps with the juggling talk, so best for any audience not to see both this and that.
The Nature of ProofThe one thing that distinguishes mathematics from all of science, art, and the humanities, is the question of "Proof". In this talk we examine what proof is, why it's important, and how we can know something is true for ever, even when we can't check every example for ourselves.

Maths In A TwistMany students are introduced at some point to the Moebius Strip, that wonderfully perplexing strip with a half twist that has only one side and one edge, and which when cut in half doesn't do what you might expect. In this workshop we don't just stop there, but explore what happens with other possible twists and turns, and try to find some way of understanding how this works, what else is possible, and whether we can make sense of it all.
