For anyone who gets their podcasts through YouTube, and for the attention of anyone who didn’t already know about the Mathematical Objects podcast, we’ve started posting old episodes on the Aperiodical’s YouTube channel, and will do so once a week (10am GMT on Mondays) until we catch up with the current episode.

The first episode is on Towers of Hanoi, and there’s a playlist where all future episodes will be added. For more information about the podcast, visit our page on the site.
