Time-Turning for Muggles: How to keep your distance

The common-sense notion of distance is also a fundamental idea in mathematics. One of the properties that mathematicians–and any sane person–typically require of a distance is that the distance between a point and itself be zero. But what if we allowed self-distance to be positive? Could we still construct meaning out of this? Are there implications of this idea outside the world of wizardry? Join us on Oct 25th for an exploration of the issue.

Additionally, senior Ben Thompson will talk about a paper he has read as part of an independent study on topology.
