I love talking about maths. Please get in touch (r [dot] elwes [at] gmail [dot] com) if you would like me to come and speak to your school or club. The sessions I currently offer include:
- Knot Theory interactive masterclass – I have versions of this suitable for beginners and for more advanced (e.g. A-level) students.
- Nim and Nimbers – an interactive masterclass on game theory and mathematical strategy, suitable for audiences of all ages.
- Unpicking Pick’s Theorem – an interactive masterclass (ideally requiring computer access for all students, working in pairs) about Pick’s theorem.
- The Maths that Makes the Modern World – a talk, suitable for A-level students, about some of the mathematics behind industry and the internet.
- Infinity and the Limits of Maths – a talk, suitable for A-level students, about infinity and the continuum hypothesis.
- The Science of Geometry and the Art of Optimisation – a talk, suitable for GCSE students, about the mathematics of optimisation.
- The Platonic Solids’ Lesser Known Cousins – a talk, suitable for all ages, about the the weird wide world of polyhedra.
- I have various talks suitable for mixed mathematical audiences (e.g. undergraduate maths societies).
