List of interesting math podcasts? mathfactor is one I listen to.  Does anyone else have a recommendation?
I would like to draw attention to the beautifully produced podcast Relatively Prime hosted by Samuel Hansen, which was funded through a successful kickstarter campaign. All eight episodes are well worth a listen and include interviews with some very high profile and influential mathematicians.
There's a new maths podcast that you may be interested in that reviews "Maths at the Movies: Interstellar plus SPECIAL GUEST" in its first series. It's a slightly anarchic look at movies, mathematics, and life: www.mathsat.co.uk (direct link to podcast MP3 audio). There are some additional podcasts included as other blog entries.
