**Order in Disorder**

**Professor Imre Leader
Department of Pure Mathematics and Mathematical Statistics, University of Cambridge**

*"Some bits of mathematics are completely free of equations: just about patterns. I want to tell you about such a bit of maths, with no equations at all, called Ramsey Theory."*

This talk was originally given to an audience of Y12 A-level Maths students (age 16/17).

**Einstein, Relativity and Gravity Waves**

**Professor David Tong
Department of Applied Mathematics and Theoretical Physics, University of Cambridge **

*"This talk will mostly be stories... I want to tell you about Albert Einstein, and about his theory of relativity - what it is, why he was thinking about it and also about some of the very latest developments that have happened just this year."*

This talk was originally given to an audience of Y12 A-level Maths students (age 16/17).

**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.*

This talk was originally given to an audience of Y12 A-level Maths students (age 16/17).

**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."*

This talk was originally given to an audience of Y12 A-level Maths students (age 16/17).

**Seeing More in Images - A Mathematical Perspective**

**Dr Carola Schönlieb
Department of Applied Mathematics and Theoretical Physics, University of Cambridge**

*Dr Carola Schönlieb gives an insight into some of the mathematics behind image analysis and its wide-ranging applications in fields ranging from developing cancer therapies to restoring artworks, together with some personal reflections on her own career journey through mathematical study and research.*

This talk was originally given to an audience of Y12 A-level Maths students (age 16/17).

**How to Solve Equations**

**Dr Vicky Neale
Mathematical Institute, University of Oxford**

*How do mathematicians solve equations? Dr Vicky Neale explores some celebrated equations to find out more, and covers some highlights from the rich history of number theory along the way.*

This talk was originally given to an audience of Y12 A-level Maths students (age 16/17).
