*"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 video contains a talk by one of our favourite physicists, David Tong at the Department of Applied Mathematics and Theoretical Physics at Cambridge. It was originally given to an audience of Year 12 A-level maths students (aged 16-17) in June this year and formed part of a mathematics enrichment day organised by the Millennium Mathematics Project with a special focus on encouraging the development of mathematical thinking.
