You may recall that Samuel Hansen and I used to have a weekly conversation about mathematics in the news and news in mathematics, which we called the Math/Maths Podcast and released through the (still going!) science communication project Pulse-Project. When we put Math/Maths on hiatus (the length of which is still an open question), this left a gap in the lucrative ‘two blokes talking about maths-y stuff’ market. Leaping on the opportunity, plucky young podcasters Colin Beveridge and Dave Gale started Wrong, But Useful (as you may recall from a previous post here). Well, that was a year ago now and, as creatures whose outlook is tied to this planet, that is apparently worth celebrating. Through a careful constructed mock-feud, Colin and Dave reeled in first Samuel and then me to join them in an anniversary recording.

### An infinite series of blog posts which sums to -1/12

Many of you who are aware of the internet will have noticed that some mild controversy has surrounded a recent Numberphile video, posted last week:

### The minch, the mound and the light-gigaminch

On Wednesday 27^{th} November 2013, friend of The Aperiodical and standup mathematician Matt Parker tweeted a link to his latest YouTube video.

In the video Matt apologises for some remarks on the imperial number system that he made in an earlier Number Hub video about the A4 paper scale. He then goes into some of the quirkiness of the many imperial number units used for measuring length. It is an unusual ‘apology’, although very entertaining.

This got me thinking about how I think about lengths, and I tweeted that I often think in ‘metric-imperial’ units of length, or multiples of exactly 25mm in my job as a civil and structural engineer – a metric inch, if you like. Colin Wright suggested the name ‘minch’ for these units; there are then two score *minch* to the metre.

### Maths at the Fringe

Starting next week, the historic city of Edinburgh will be taken over by entertainers of all types, performing comedy, dance, theatre and music, entertaining visitors to their massive world-famous festival fringe. Since discerning mathematicians sometimes also enjoy being entertained, I thought I’d write a roundup of the shows maths has non-empty intersection with.

First up, since we haven’t mentioned him in a while, it’s Alan Turing! No, his reanimated corpse isn’t performing edgy stand-up, but theatre company Idle Motion is performing a visual theatre piece entitled **That Is All You Need To Know**, celebrating the work of Bletchley Park codebreakers. Alan Turing Alan Turing Alan Turing.
