In this year's advent calendar we revisit some of our favourite episodes of our Maths on the move podcast. We're lucky to get to speak to lots of interesting mathematicians throughout the year, and our podcast captures many of those fascinating conversations, explores the maths people do, and why they love doing it.

Whether it's the maths of chocolate, new breakthroughs in pure mathematics, or the mathematical sound of music, we hope you enjoy this selection of Maths on the move episodes!

You can subscribe to our podcast through Apple Podcasts, Spotify and through most other podcast providers via podbean. And you can follow Plus on Twitter and Facebook or get Plus delivered straight to your inbox!

Some of this content is part of our collaboration with the Isaac Newton Institute for Mathematical Sciences (INI), an international research centre and our neighbour here on the University of Cambridge's maths campus. INI attracts leading mathematical scientists from all over the world, and is open to all. Visit www.newton.ac.uk to find out more.
