Queen Elizabeth Chess Moves | Know Your Meme
Be careful, she can move in any direction

Quanta Magazine reports, beautifully as always, that there’s been some progress on the n-Queens problem, which is about finding how many different ways queens can be placed on a chessboard so that none attack each other. Since the problem is difficult to simplify, it’s historically been a case of crunching through all the possibilities, but the new breakthrough pinpoints the number of positions on an n-by-n board by sandwiching it between upper and lower bounds that now coincide.

According to Science News, “An elusive equation describing bird eggs of all shapes has been found at last”. Now, if you simply know the egg’s length, its maximum breadth, its diameter at the spot where its pointed end terminates and the location of its maximum diameter in relationship to the midpoint of its length, you can calculate its volume.

Aperiodical News Roundup – September 2021

Here’s a collection of some things that have been happening (and will be happening) in maths this month (and next month).


The British Society for the History of Mathematics have announced their annual Neil Bibby Awards, which have been awarded to Ciarán Mac an Bhaird and Michael Barany. The award winners receive £400 each, and will be expected to deliver some schools talks and produce resources for the BHSM website. More information about the Bibby Awards can be found on the BSHM website. (via @MathsHistory on Twitter).

The British Society for the History of Mathematics have also announced the winners of their annual schools and undergraduate essay prizes:

  • Schools Writing Prize (11-15 category): Daria Gal (Notting Hill and Ealing High School, London) for ‘Mathematics and the mysterious world of creating gold’;
  • Schools Writing Prize winner for 2021 (category 16-19): Carys Williams (Monmouth School for Girls, UK) for ‘A story of secrecy and security: the key to unlocking prime numbers’;
  • Undergraduate Prize winners, jointly: Ellen Flower (Oxford University) for ‘The “analysis” of a century: Influences on the etymological development of the word “analysis” in a mathematical context to 1750’ and George Waters (London School of Economics) for ‘Exploring the use of mathematics to obtain consensus’.

These winners and the runners up for each prize are announced in this Twitter thread: “Our Schools and Undergraduate Prizes announcements!!!”.

Money, Dollars, Sack, Bag, Icon, Bag Of Money

Carnegie Mellon University has been gifted $20 million by blockchain pioneer Charles Hoskinson to establish the Hoskinson Center for Formal Mathematics. The center will be part of Dietrich College and will “advance mathematical research by improving global access to knowledge and resources for mathematics researchers, educators and learners”. For more information read the press release here. (via @KevinZollman on Twitter).


This coming Ada Lovelace Day, Tuesday 12 October, the organisers of Ada Lovelace Day live are putting on a series of online webinars on topics including engineering, tech and games, and the science of hypersleep. Tickets are free, and the events will be streamed live on YouTube and Facebook.

School student stage show outfit Maths Inspiration are putting on a special online show during COP26, themed around the mathematics of climate. Schools can pay a flat fee of £75+VAT to have as many students as they want join and watch live, and speakers include Matt Parker, Sammie Buzzard and Hugh Hunt. (via @MathsInspiratn on Twitter).

Screenshot from the MathsCity website, with text: 'EXPLORE - DISCOVER - SOLVE; MathsCity is the home of hands-on maths, located in the heart of Leeds. Coming soon to Trinity Leeds, the UK's first Mathematics Discovery Centre.'

It’s finally happening! The UK’s first hands-on maths discovery centre, MathsCity, will be opening in Leeds on 5th October. Open from 10am-5pm Tuesday-Sunday, in Leeds Trinity Shopping Centre, the mathematical wonderland will include giant bubbles, a laser ‘ring of fire’ and puzzles to solve. Go go go! (via @MathsCityLeeds on Twitter).

On 15th October, the Royal Irish Academy is hosting the Hamilton Lecture 2021, featuring Professor Caroline Series, who’ll be talking about Glimpses in Hyperbolic Geometry. The lecture will take place online, followed by a Q&A, and tickets are free but booking is required. And look, they did such a cool poster (above)!

Aperiodical News Roundup – August and half of September 2021

Here’s a round-up of mathematical and maths-adjacent things that happened in the world this month-and-a-half.

Mathematical News

New record calculation of π – a team in Switzerland have calculated π to a record accuracy of 62.8 trillion digits (that’s around 10 tau trillion – a masterful troll). For more background, read New mathematical record: what’s the point of calculating pi? in the Guardian, which strikes a nice balance between understanding that π is important but that this kind of record-setting is largely stamp collecting.

Odd subgraphs result – There’s also a nice writeup in Quanta of a new proof confirming a fact about odd graphs (that every graph has a subgraph at least $\frac{1}{10000}$ of its own size that contains entirely odd vertices).

P vs NP proof – Logician Martin Dowd is claiming a proof of P≠NP “using a Godel diagonalization argument involving representing formulas”. As per @HigherGeometer’s tweet, mathematicians will be looking for the ‘nearly inevitable slip’, and we’ll report it here if we notice an announcement, probably.

Prime Gap now down to 20 – Another claimed proof, this time by arithmetic geometer Chunlei Liu, confirming that there are infinitely many primes at most 20 apart – an improvement on prior work by Zhang/Polymath8/Tao/Maynard, and using a similar method.

Events & Awards

Awards news – This year’s Royal Society Medals have been awarded, and recipients include Prof. Frances Kirwan who has been awarded the Sylvester Medal “for her research on quotients in algebraic geometry, including links with symplectic geometry and topology, which has had many applications”, and Prof. June Barrow-Green who receives the Wilkins-Bernal-Medawar Medal and Lecture “for her research in 19th and 20th century mathematics, notably on historical roots of modern computing, dynamical systems and the three-body problem. Her work places special emphasis on the under-representation of women in historical narratives and in contemporary mathematics.”

Maths competition award nominations – The World Federation of National Mathematics Competitions has put out a call for nominations for the Erdos Award 2022, which recognises the contributions of “mathematicians who have played a significant role in the development of mathematical challenges at the national or international level and which have been a stimulus for the enrichment of mathematics learning”. If you know someone who runs maths competitions and deserves an award, it’d be great to see some more UK winners!

Win a free Schools Workshop – ICMS and Maths Week Scotland are excited to announce a 2021 School Workshop competition, in which Scottish secondary schools can register themselves on the Maths Week Scotland website and enter to win an interactive virtual maths workshop delivered by Ben Sparks or Katie Steckles (that’s me), during Maths Week Scotland.

And Finally

Nira vs Specsavers – We previously reported on Nira Chamberlain’s social media crusades to stop brands from being flippant about maths – and it looks like he’s had some more success. Following his complaint about an unhelpful leaflet put out by Specsavers (in which algebra was described as ‘silly’ and used as a throwaway example of something hard) they’ve responded to him personally and withdrawn the leaflet.

Gathering For Gardner is postponed again – with a heavy heart, the organisers of Gathering For Gardner 14 have made the tough call, in light of “the continuing worsening of the COVID-19 situation in Georgia, with record-breaking numbers of infections, and an increase in hospitalizations throughout the state”, to postpone this year’s event to 2022. Tickets already booked can be transferred to next year’s event or fully refunded.

Carnival of Mathematics 197

The next issue of the Carnival of Mathematics, rounding up blog posts from the month of August, is now online at Math ∩ Programming.
