Eugenie Hunsicker and collaborators have produced a film entitled “Words of Women in Mathematics in the Time of Corona”, which raises awareness of the impact of the pandemic on women in mathematics.

The QE Prize for Engineering’s ‘Month of Making’, as featured previously in a post announcing the start, is well under way and continues until 12th December, with scientific, mathematical and engineeringy ideas for make-it-yourself gifts every day.

This month saw the official launch of MathsCity Leeds, as previously covered in this review by hands-on discovery centre correspondent Peter and his son.

A new paper has been published in Nature about the use of machine learning in pure maths research. This isn’t machine learning making new maths, but rather it’s pitched as a collaboration between mathematician and machine – the authors argue that machine learning can be used “to guide intuition and propose conjectures”. The paper gives some examples of new fundamental results in pure mathematics that have been discovered with the assistance of machine learning.

Open Calls

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.

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.

Aperiodical News Roundup – July 2021

Here’s a round-up of the latest mathematical news from the month of July 2021.


The Society for Industrial and Applied Mathematics, SIAM, has announced the winners of its 2021 prizes. Winners include: student paper prizes to Yingjie Be, Michelle Feng and Yuanzhao Zhang; the George Pólya Prize for Mathematical Exposition to Nick Higham; and the John von Neumann prize to Chi-Wang Shu.

The Institute of Mathematics and its Applications, the IMA, has also announced some prize winners.

And since we’re talking about mathematicians winning awards, mathematician Anna Kiesenhofer has been awarded a gold medal in the women’s cycling road race at the Tokyo Olympics. For more information, read her 2016 paper Noncommutative integrable systems on b-symplectic manifolds (actually, it may not mention the Olympics at all, sorry).

Laurent Fargues and Fields Medalist Peter Scholze have created “a long-desired bridge between the arithmetic and geometric sides of the Langlands program”, warranting a writeup in the always-excellent Quanta Magazine. (Via @KSHartnett)


If one science communication video contest run by a famous YouTuber this year wasn’t enough, Grant Sanderson (aka 3blue1brown) is running a Summer of Math Exposition. Submit an “explainer of math” to be in with a chance of a $1,000 prize. Imagine the Big Internet Math-Off, but with less voting and an actual prize. Grant announced the competition with a video titled “Why aren’t you making math videos?”:

Because we’re tired, Grant. We’re so tired.

The IMA Black Heroes of Mathematics 2021 conference will take place on the 5th and 6th of October. The vision of the conference is “To celebrate the inspirational contributions of Black role models to the field of Mathematics and Mathematics Education”. The event will include technical talks by internationally renowned Black speakers, incorporating details of their career paths and experience.

Other news

The Protect Pure Maths Campaign, funded by private donations and run by a PR firm in collaboration with the London Mathematical Society, aims to promote and protect pure mathematics research. The family of Alan Turing have added their support to the campaign, to protect what is described in this article in the Guardian as ‘blue skies maths’.

The IMA has announced they’re forming an alliance to create new professional standards for data science.

“The Alliance for Data Science Professionals is defining the standards needed to ensure an ethical and well-governed approach so the public, organisations and governments can have confidence in how their data is used.”

The alliance consists of the Royal Statistical Society (RSS), BCS, The Chartered Institute for IT, the Operational Research Society, the Institute of Mathematics and its Applications, The Alan Turing Institute and the National Physical Laboratory (NPL), supported by the Royal Academy of Engineering and the Royal Society.

Robert Moses, founder of math literacy promotion charity The Algebra Project, has died. The announcement on the project website includes a moving tribute:

“His transition to that higher level only inspires us all to love, struggle and live with and for our people as he did, as we continue to work to realize Bob’s vision of “raising the floor of mathematics literacy” for all young people in the United States of America.”

Brands are at it again with their weird unnecessary anti-maths schtick: take this recent effort from Specsavers in which they state algebra is hard (which it can be sometimes), but also imply it’s ‘silly’, which is pretty short-sighted of them (LOL). Also this month, IMA President and World’s Most Interesting Mathematician Nira Chamberlain has been hassling sofa chain DFS about their TV commercial in which a boy shouts ‘I HATE MATHS’ repeatedly – which may actually have resulted in a change to the broadcast version (and good work if so!). It turns out that calling out this kind of thing sometimes gets results.

And finally, it’s been anounced that the theme for the International Day of Mathematics 2022 will be “Mathematics Unites” (via Nalini Joshi).

Aperiodical News Roundup – June 2021

Here’s a round-up of mathematical things that happened in June, and things you might want to know about that are happening in the future!


News In Brief

Thumbnail of Veritasium video 'A Physics Prof Bet Me $10,000 I'm wrong' with an image of the two physicists and the caption 'Who's right'
  • YouTuber and PhD physicist Derek Muller (Veritasium) has recently been involved in a physics-off with UCLA professor Alexander Kusenko, when they disagreed over the explanation behind a physical phenomenon, which escalated to a $10,000 bet over who was right. Long story short, Veritasium won the bet (as covered in this IFLScience news story) and will be using the money to fund a science communication contest. If you’ve got an under-a-minute maths/science video you can post on YouTube or TikTok, you could win a prize of up to $5,000. Props to Derek for encouraging more STEM communication and promoting new talent!
  • It’s been formally announced that Neil Sloane is stepping down as president of the OEIS – Russ Cox will take over presidential duties, while Sloane steps down to Chairman of the Board so he can dedicate more time to his writing projects (which we’re assured ‘naturally involve sequences’). Cox has been involved with the OEIS for over 25 years and has been a major contributor to the backend software that makes the site run, so he’s a safe pair of hands to take the project on.
  • The eleven 2021 LMS Prize winners were announced at the Society’s Meeting on 2nd July, and the prizes recognise contributions to mathematics in a variety of areas. (via @LondMathSoc)

Alan Turing £50 note launches

On 23rd June the new Alan Turing £50 note was launched, featuring an image of Turing, a quote and various mathematical diagrams. Bletchley Park marked the occasion with a #Turing50Takeover, and the Bank of England has a whole page of info about the new polymer note on their website.

Meanwhile, in Turing-adjacent news, the National Museum of Computing has launched an online Virtual Enigma machine you can use to simulate the device behind the famous Enigma code, along with a video explaining the machine. This joins a host of other virtual historical computers they’ve built, including the Colossus that cracked the code, the Lorenz machine and even ERNIE the random number generator!

Claimed proof of Riemann Hypothesis

Another claimed proof of the Riemann Hypothesis, this time by Kumar Easwaran, emerged this month, and since like all big claims it would need thorough checking before acceptance by the mathematical community, there was some initial skepticism. (This didn’t stop the media from latching on to it as an exciting story though). Since claimed proofs of Riemann are like buses, many mathematicians don’t give them much attention, but Alex Kontorovich took the time to thoroughly debunk this one to save you the trouble.

If you want some actual Riemann Hypothesis news, here’s some: John Baez reports that Alain Connes and Caterina Consani have made some potential progress on part of the problem. In the words of Baez, “my interest is piqued”.

Interesting Links

Thuses is a website for mathematicians to publish and discuss ideas of interest to the mathematical community. It’s described as “a perfect place to share new approaches, slick proofs, and surprising counterexamples. A place for ‘folklore results’ that are considered known but don’t actually exist in literature. A place for everything in math that just has to be shared.” (via Piper H)

The Royal Society has published a set of papers on modelling that shaped the early COVID-19 pandemic response in the UK as a special journal issue that’s free to access.

The BSHM (British Society for the History of Mathematics) has launched the Bibby Awards in the History of Mathematics, for “contributions to the popularization of the history of mathematics in education”. Named after (and funded by the legacy of) the late BSHM member Neil Bibby, up to four awards of £400 can be made each academic year, in return for which holders are expected to give two free talks in schools and produce four digital resources (videos, PDFs or interactives) for the BSHM website.

The Isaac Newton Institute in Cambridge is hosting The unity of mathematics: A conference in honour of Sir Michael Atiyah which will take place in September 2021 as a hybrid event with a mixture of in-person and virtual talks. The closing date for registration for physical participants is 8th August.

There’s just about still time to register for the People, Places, Practices History of Maths Conference (registration closes 9th July) taking place 12-15 July online (coordinated by the University of St. Andrews). With around 90 speakers contributing, the programme looks packed, and talks will be available to watch ahead, or at the specified time to be followed by a live Q&A.

Alexandre Borovik reports on his blog about Azat Miftakhov day, an event organised online by the Azat Miftakhov committee in solidarity with Azat Miftakhov – a graduate student from Moscow State University who was sentenced to six years in a medium-security penal colony and has already been arbitrarily detained by Russian state authorities for almost two and a half years. Fields medalist Cedric Villani made a speech at the event, and you can watch videos from the event on YouTube.
