Our Open Days are intended to give an insight in to Maths at Oxford, whether you are a potential applicant or are just curious. In this talk to an audience of sixth-formers (High School students) and their families, about the Applied Maths that our undergraduates study at Oxford, Dominic Vella uses everyday examples to explain that Applied Mathematics is about looking afresh at the world around you, looking at scientific problems and using mathematical models to solve them.
