This is a re-airing of a podcast originally released in January 2021.

An episode of Escape Pod all about understanding. We start by discussing the self-awareness of dolphins and whales, and the intricacies of their language and vocalisations. Then we marvel at the seemingly impossible abilities of gymnasts and ballerinas, most notably Simone Biles who performed a legendary triple double. And then we take a look at the Chinese board game Go - a game with more possible moves than there are atoms in the universe.

On the pod are Rowan Hooper, Anna Demming and Timothy Revell. Find out more at newscientist.com/podcasts
