Watch our Y12 enrichment day talk videos online

Even if you missed our Year 12 Mathematics Enrichment Day in June 2015, you can now watch the two plenary talks online. 132 Year 12 students (aged 16-17) from 17 different schools took part in the full-day event on 19 June 2015, which had a special focus on encouraging the development of mathematical thinking. The enrichment day programme included two talks: Dr Vicky Neale explored some fascinating aspects of prime numbers, while Professor Ben Allanach gave an overview of the discovery of the Higgs boson and how current research at the LHC might provide insights into dark matter. In addition, each student took part in two different small-group mathematical workshops over the course of the day. The workshops were run by members of the NRICH and Cambridge Mathematics Education Project team, and explored mathematical topics including number theory, graph theory, geometry and proof through paper folding.

7 Things You Need to Know About Prime Numbers Dr Vicky Neale Mathematical Institute, University of Oxford Prime numbers are fundamentally important in mathematics. Discover some of the beautiful properties of prime numbers, and learn about some of the unsolved problems that mathematicians are working on today.

The LHC and the Dark Matter Mystery Professor Ben Allanach Department of Applied Mathematics and Theoretical Physics, University of Cambridge "As a theoretical physicist I spend a lot of my time thinking about fundamental particles smaller than an atom. But I also spend some of my time thinking about the Universe, which is about as big as you can get. ... I'd like to take you on a journey to the very small and the very large."
