Good news! The first episode of a new maths podcast, Relatively Prime, came out this week and it's a good 'un. Host Samuel Hansen has taken the plunge by interviewing our favourite statistician, David Spiegelhalter, and a host of others to explore some fascinating mathematical tools: game theory, risk and relief geometry.

There'll be a new episode every monday for the next seven weeks, so stay tuned to the website, or subscribe using RSS or iTunes.
