*In this series of posts, we’ll be featuring mathematical podcasts from all over the internet, by speaking to the creators of the podcast and asking them about what they do.*

We spoke to maths podcaster Erik Seligman about his self-published podcast *Math Mutation*.

**Podcast** **title**: Math Mutation**Website**: mathmutation.com**Links**: Apple – RSS**Average episode length**: 5 minutes**Recommended episode**: 258 – Memory or Knot

#### Tell us about your podcast.

It’s about interesting, fun, or weird math (or math-adjacent) tidbits that can be explained in 5 minutes or so. It’s for people of any age curious about expanding their minds with math-related knowledge, or with insights math can provide in other areas.

I release about 1 episode per month. It’s a simple format, just me chatting with the audience about the topic. For the first couple of years I tried to do it weekly, but couldn’t keep up that pace…

#### What’s special about your podcast?

This one is not concerned with homework help or repeating stuff you heard in school – I focus on interesting ideas on the boundary of mathematics that you likely haven’t heard elsewhere.

#### Which episodes would you recommend for someone wanting to listen?

Some of my recent favourites, as well as 258 – Memory or Knot mentioned above, include 257 – Turning Things Sideways In Time, 254 – How To Annoy Your Cat and 252 – A Mathematician Translating Pushkin.

#### Any plans for the future?

To continue podcasting! Highlights of the first 200 episodes are now available in a book (*Math Mutation Classics,* from Apress/Springer). If I make it to episode 400, maybe I’ll publish another volume!

Also, I’m not getting any younger… maybe if I retire from my day job in a few years, I’ll start making episodes more frequently again.
