The presenters of this episode of Talkdust are Belgin Seymenoğlu and Emily Maw. Music and editing by Matthew Scroggs, and announcements by Tom Rivlin. In this episode:

• Belgin and Emily talk about going to two very different conferences.
• Belgin and Emily talk to Jason Lotay, who is now Professor of Pure Maths at the University of Oxford but was a Professor at UCL at the time of recording.
• Belgin and Emily discuss a fact about angles in 3D shapes.
• Belgin and Emily play a game of No more integers.

Note: In the No more integers segment, Emily is clearly using $k$ to denote one of the unit octonions, and not a unit quaternion as it may be more traditional/sensible to do.

You may have noticed that in the editorial of issue 08, we mentioned that we had begun work on a Chalkdust podcast. Today, we are very excited to announce that the first episode of Talkdust, a podcast for the mathematically curious, is now available.
