**Geometry
Tea**

Geometry tea is a seminar series in Cambridge covering geometry in all it's forms. It's usually given by PhD students or postdocs. Talks (usually) take place on Fridays in MR13 at 3pm, and are followed by tea and biscuits in the Pavillion E common room. If you would like to give a talk or invite a speaker please contact Joe (jaw66@cam.ac.uk). Expenses can be provided by the department for external speakers, roughly on the level of travel from London.
