This year has been frankly ridiculous. And while we’ve done our best to cover all the hot maths topics throughout, we have inevitably missed a few. Here’s some mathematical news bits and bobs from 2016 which we (and you!) may have not noticed.

Aperiodipal numero uno Samuel Hansen’s acclaimed podcast series Relatively Prime is back, on a new monthly schedule, with an episode about how PhD student Ibrahim Sharif designed a lottery to award licences to sell cannabis in the state of Washington.
When the stakes are so high (geddit?! – Ed.) you have to be really sure that your lottery is fair. That’s where a lot of fun maths comes in.
You can listen to Lottery Daze on relprime.com. Sam intends to fund this new incarnation of Relatively Prime through Patreon – you can pledge to pay Sam a certain amount (starting at a dollar) for every episode he releases, with perks for paying more such as a postcard from Sam or placing an ad in one of the episodes.

The Association for Women in Mathematics in the USA is running its annual essay contest again, open to students in three age categories from Grade 6 to undergraduate.
Here’s the blurb:
To increase awareness of women’s ongoing contributions to the mathematical sciences, the Association for Women in Mathematics (AWM) and Math for America are co-sponsoring an essay contest for biographies of contemporary women mathematicians and statisticians in academic, industrial, and government careers.
The essays will be based primarily on an interview with a woman currently working in a mathematical sciences career. This contest is open to students in the following categories: Grades 6-8, Grades 9-12, and College Undergraduate. At least one winning submission will be chosen from each category. Winners will receive a prize, and their essays will be published online at the AWM web site. Additionally, a grand prize winner will have his or her submission published in the AWM Newsletter.
The deadline for entries is January the 31st 2017, and if you want the AWM to pair you up with an interviewee, you need to get a request in by January 10th.
All the prize-winning essays from previous years are online, including this nice one about Tanya Khovanova by high school student Emily Jia.
Back in 2013, our own Christian Lawson-Perfect came up with a way of making a solid from the smallest non-Hamiltonian graph, the Herschel Graph. Called the Herschel Enneahedron, it’s got nine faces (three squares and six kites) and the same symmetries as the graph itself.
The most recent news is that Spektrum magazine – sort of a German version of New Scientist – has included in its regular puzzle column a Herschel Enneahedron-related challenge. Here’s Google’s best effort at translating it:
Please make a polyhedron of 3 squares and 6 cover-like kite rectangles with suitable dimensions (in your thoughts, drawings or with carton). What symmetry properties does it have, how many corners and edges? Is it possible to make a (Hamilton-) circular path on its edges, which takes each corner exactly once and does not use an edge more than once?
Before you get out your cartons and start working on this, given that we started from a graph which isn’t Hamiltonian, you may have a slight spoiler on the answer here… but the solution given includes some nice videos and explanation as to how the solid is formed.

The Science Museum in London has for a long time had a maths gallery; if you didn’t already know that, it’s probably because it was old, stuffy, full of random maths objects (so, very cool if you’re me), and not very easy to find. They’ve updated the gallery, working with the architect Dame Zaha Hadid, to produce a new space which hopefully brings the gallery up to date.
After a preview opening event, reports seem to be largely positive – the gallery has taken the approach of focusing on the way mathematics impacts the real world, rather than the actual maths itself. It contains lots of interesting artefacts and stories about the history of the way people have interacted with mathematics, although according to observers, no equations (boo!).
It’s been written up by a few design-focused websites, but the best articles to get a sense of it are Alex Bellos’ write-up in the Guardian, and a piece by BBC arts editor Will Gompertz (although one wonders if the BBC couldn’t have sent their science, or in a magical fairyland, maths correspondent to cover this).
The gallery is open at the Science Museum, Exhibition Road, London, starting 8th December, daily from 10am-6pm, and is free to visit.

There seem to be a bumper list of mathematical advent calendars this year, even though the stellar efforts of Katie and Christian’s Aperiodvent Calendar 2015 aren’t being repeated. There aren’t yet enough for an advent calendar with a different mathematical advent calendar behind each door, so we thought a straight round up was the way to go.
