According to a new ArXiV paper, the triple bubble conjecture (a result about the shapes taken by surfaces that are attempting to enclose a volume, or in this case three volumes, with minimal surface area) has been solved. (via Ian Agol)
A big month for prizes, with the announcement of the 2022 Fields medals, awarded to Hugo Duminil-Copin, June Huh, James Maynard and Maryna Viazovska, as well as the 2022 Christopher Zeeman medal, which has been awarded to Simon Singh.
In the UK, schools have now broken up for the summer, or are about to, meaning parents face a long six-to-eight weeks of trying to find interesting things for the kids to do. If you or someone you know is in this situation, and the kid(s) in question would like to do some mathematics, we’ve got you covered.
Online resources for primary (ages 5-11)
Always a good shout for mathematical things to do, the wonderful NRICH, who are based at the University of Cambridge, are posting interactive mathematical challenges every weekday from now until 2nd September.
Family maths charity Maths on Toast are posting weekly STEAM activities including craft, construction, puzzles, baking and games, under the banner of Summer Fun with Little Robot. They’re also running a ‘Join-in Project’ themed around Truchet tilings, called Infinity Tiles – participants can send in their own ideas to be featured in an online gallery.
While there aren’t specific summer-themed activities, there are plenty of great resources and thoughts about ways to engage with young mathematicians on the Talking Math With Your Kids website.
If you can get to Leeds, we can highly recommend the wonderful maths discovery centre at MathsCity – with tickets at £6.50 for adults / £4.50 for children aged 3-16 / £18 family ticket, and within easy reach of Leeds train station, it’s a great day out and you can spend hours playing with the interactive exhibits and puzzles. They’ve just launched a great new codebreaking exhibit for this summer, with over 20 interactive coding activities and crafts. There’ll also be bubble-related activities on 6th August, and they’ll be represented at Leeds’ Breeze in the Park events on 17th & 18th August.
In the north-east, numeracy initiative Multiply is running three Multiply Roadshow events in Gateshead. The events will feature much-loved celebrities including Johnny Ball, Scarlett Moffatt and Coronation Street’s Ryan Thomas, alongside family games, crafts, and activities, as well as information about short fully funded maths courses from Gateshead Learning and Skills. (Sadly the Johnny Ball event is happening as we write, but the others are 8th & 15th August).
The Royal Institution in London has a large programme of summer holiday workshops running from 25 July to 26 August, which cost £35 half-day / £50 full day, with discounts available for Ri Young Members. Bursaries to support attendance are available via the Potential Trust (details on the individual session pages under ‘About Our Workshops’).
Bletchley Park remains the classic mathematical historical day out: tickets are £24.50 for adults, £16.00 for 12-17 year olds and it’s free for under-12s – plus the ticket is an annual pass, so you can visit as many times as you want in a year. Over the summer they have a Summer Fun programme including Puzzles and Pastimes on Tuesdays, Wednesdays and Thursdays, family guided tours on Fridays, a summer concert series and Top Secret Mission Packs available on entry for £1. They also currently have a temporary exhibition on the Art of Data.
Honourable mention for site-friend Kyle Evans who’s performing his family (7+) maths show Return of the Math(s) (left) at the Edinburgh Fringe from 6-15 August – a ‘fast-paced hour of inclusive maths-based family fun [… including] madcap demos, loads of crowd participation and mind-melting mathematics.’
This semester I’ve been teaching a module that covers a couple of different maths topics, and have been setting little puzzles for my students to complement what they’re learning – and some of them have been quite fun to write and play with. I thought I’d share some of them here, so you can enjoy them too.
The Spectra Math (@LGBTMath) account has announced that the AMS (American Mathematical Society) has instituted a new policy, based on consultations with Spectra, concerning author name changes. The policy is intended to make its journals more inclusive, especially of trans and non-binary researchers. The policy seeks to provide a simple and efficient way for authors to update their name on published articles in a minimally intrusive way that respects the author’s privacy.
The Eindhoven University of Technology has advertised a post for a Full Professor in Applied Algebra and Geometry, which for the first six months of being advertised will only be open to female candidates. The post is part of the Irène Curie Fellowship program, which is dedicated to reaching at least 30% female researchers on TU/e’s permanent academic staff by 2024.
Igalia, contributors to digital maths writing standard MathML, have announce their intent to ship MathML support in Chromium going forward. They claim this announcement is a big step towards having MathML support enabled in Chromium (and hence Chrome) by default. (via Deyan Ginev on Twitter).
In a paper titled ‘The Next 350 Million Knots’, mathematician Benjamin A. Burton at The University of Queensland has enumerated all knots up to 19 crossings, meaning we now have a total of 352152252 known distinct non-trivial prime knots (only infinity to go!) (via Ian Agol).
Google’s Emma Haruka Iwao, architect of a previous large π digit calculation record announcement in 2019, is at it again: the 100 trillionth digit of π in base 10 has been revealed to be (spoiler alert) 0. According to a post on the Google Blog, the calculation took over 157 days and processed around 82,000 terabytes of data.
The ICMS (International Centre for Mathematical Sciences) in Edinburgh has instituted a visiting fellow in music, with the inaugural recipient being Julien Lonchamp, an orchestral composer who has scored a number of short films.
He is interested in how sound and music work at the interface with other disciplines, including visual art and science. He aims to create novel immersive “sound-worlds” by combining a wide range of composition processes in order to communicate abstract or complex ideas.
