The maths and magic of shuffling

Will Houstoun and Cheryl Praeger

We all have our favoured methods of shuffling cards, but most of us don't think any more about it once we've started playing a game. But there's so much more to be discovered! In this podcast mathematician Cheryl Praeger and magician Will Houstoun reveal the maths and magic behind shuffling cards. And to celebrate our new collaboration with the Isaac Newton Institute, Dan Aspel tells us all about the INI!

You can watch Cheryl Praeger talk about the mathematics of shuffling in her Kirk Lecture at the INI in 2020. You can be astounded by Will Houstoun's magic, including the amazing trick we mentioned in the podcast, and find out more about his work as magician in residence at the Imperial College London and Royal College of Music Centre for Performance Science, at his website. And you can read all the details behind the maths and magic of shuffling in their Plus articles: The magic of shuffling and The mathematics of shuffling.
