The Mathematics of Card Shuffling: A Journey Towards Randomness
How many shuffles does it take to mix a deck of 52 playing cards? Behind this simple question lies a surprisingly deep mathematical theory. In this lecture, we explore what it means for a deck of cards to be ‘well mixed’, examine several classical shuffling methods, and see why certain methods require far more iterations to produce a random deck than others. We will view card shuffling through the lens of random walks, a mathematical framework used to model phenomena across physics, evolutionary biology and beyond.

The presentation will be followed by discussion and drinks. The event is free. Registration required via the form below.
