A story about coordinate systems, teenagers, and comedian parents: I went to see the London Symphonic Rock Orchestra with my 14 year old at the weekend. (They were incredible. If you have the opportunity to see them, you should go.)

Knight's tours and Ursula Le Guin in the same post ❤️❤️❤️

Day ☀️♥️

Night 🌙💙

No joke: I got angry hate mail today for writing an obituary of a Black woman scientist—because the person felt she did didn’t deserve the recognition. Which just makes me want to share it again: www.nature.com/articles/d41...

And it shows some obvious ways in which TV shows can do harm - both to individuals, many of whom were hoping this would finally 'prove' they were smart, and to society, when the myths are upheld by this kind of lazy and thoughtless design.

It reveals some persistent myths about the idea of a ‘genius’ – that some people work lightning fast, are better alone, or have ‘innate’ skills, for example.

It's show week! There's still time to grab yourself a ticket for "An Evening of Unnecessary Detail" at Winchester Cathedral on 5th February! Join Helen, Matt, Steve and special guests Lucie Green and Jen Gupta beneath Luke Jerram's Helios! www.hampshirechronicle.co.uk/news/2581004...

New video about maths communication! What makes Numberphile videos so effective? I analyse how these videos explain maths, and try talking about the Monty Hall problem in the iconic Numberphile style myself. @bradyharan.bsky.social youtu.be/MsCp0In-5As?...

I combined two of my favourite hobbies - making triangle animations and noodling with piano exercises. youtu.be/TPxi3xkwqDQ

Did you know I run a free 🎭 STEM-Improv Newsletter ⚛️ for STEM-Folks? Details are here: katherineholmespublic.wordpress.com/improv-and-c... *STEM-Folks are anyone who loves engaging with STEM topics. No improv experienced required. The only restriction for events is an age-rating 18+. (1/4)

The Little Event was my 1st #SciComm Event back in 2016 when I still wasn't quite sure if it was for me. 10 years & 10 BIG Events later and I've carved out a place for myself in SciComm - including now as Chair of @big-stem-network.bsky.social! Where could #LittleEvent26 take you?

I heard on the radio last week that there are in the region of 67,000 recordings of Gershwin’s song, Summertime. Of course I had to check this out.

To brighten up your Sunday morning, a tiling with rotational symmetry of order 20 made of pentagons. Constructed using ideas from Klaassen (2016) arxiv.org/pdf/1509.06297

Bored over the festive season? We're still seeking contributions to our ridiculous saytheprime.com video project: sign up and make a 5-minute video of yourself saying a chunk of digits of the largest known prime number. Can we finish before they discover a bigger one? It's a race against maths!

Looking for some nerdy drawing fun over the next few weeks? My Xmas & New Year zines are available to download for £1 (or more) and you’re welcome to print as many copies as you want! They’re A4 but I’m told can be printed on Letter paper & trimmed #SciArt ko-fi.com/hanaayoob/shop

It is an acceptable risk that some people who don’t “deserve” it accidentally get help, if it means everyone who needs it is guaranteed to get help.

This is such a shameful decision by GirlGuiding. Quite literally disempowering from an organisation that promises to 'help all girls know they can do anything' and who work within nature - a space that already systemically excludes minorities. This will hit a lot of kids hard.

Still an epsilon number of seats left for tomorrow night's Big London Show which don't have the view blocked by a safety rail. That said: I promise to move around the stage so much that no one rail can block me for long. lwtheatres.co.uk/whats-on/mat...

In August we performed at Warwick Arts Centre as part of Talking Maths in Public, described by one reviewer as "a beautiful piece of maths communication". We had a blast, and we've packaged up a few of the songs into a playlist for your listening pleasure. youtube.com/playlist?lis...

Don't forget we have a shop selling Big MathsJam merch - from t-shirts to tea-towels, buy something with MathsJam on it to show your appreciation for recreational maths.

New maths resources alert! We now have a cellular automata activity on 15minutemaths.com, made by the lovely @alisonkiddle.bsky.social - grab yourself some printables, slides and session leader notes to run an interesting and mindful maths activity!

Does anybody have any ideas where a 15-year-old could do work experience in music tech or a related area? He plays guitar, bass and drums and is also interested in production. Preferably east Kent, though may be able to travel. The school work experience week is 6-10 July 2026. Thank you!

Really looking forward to speaking and singing at the Maths Week England launch and being part of such a great line up of speakers mathsweekengland.co.uk?p=10473

The @ima-maths.bsky.social seems quite proud they invited BAE to speak at their conference. I am so so disappointed that an institution which normally funds sweet creative maths projects and supports maths communities has chosen to platform BAE Systems which produces munitions used in genocide.

I am so delighted to invite you to this event, hosted by the British Educational Research Association, in December: www.bera.ac.uk/event/arts-b... where I and Joe will be talking about writing songs about research! ✍️🎵

I'm looking forward to Inside Maths again! Maths enrichment day, 9 Feb 2026, for year 5 and their teachers, at the Ri, London. Featuring @robeastaway.bsky.social and Fran Watson, hands-on activity and puzzles. Feedback from last year: insidemaths.co.uk/feedback Book here: insidemaths.co.uk/booking

I'm horrifically late posting about this, but the playlist for the August/September Animation Generation Collaboration is now up! The prompt was to create an animation of a Hilbert curve, and there are some lovely ones! www.youtube.com/playlist?lis...

Q: What do you get if you cross a mood ring with a pronoun pin? A: My latest design at canopyrobin.etsy.com/listing/4376... Please share!

On the Saturday evening at MathsJam, we gather around the metaphorical campfire with instruments and voices to sing songs that have been reimagined with mathematical lyrics. Find out more, and how to submit lyrics, at mathsjam.com/gatheri...

Want a cool Nature, #SciArt, or Dropout Pride pin that helps a trans small business? My designs are available at canopyrobin.etsy.com and ship worldwide* *currently not to the US or Israel

Join me in 15 minutes in a livestream and watch me struggle to code an animation about the Hilbert curve! #MathsAnimationTMiP

I built a Hilbert curve out of matchsticks for #MathsAnimationTMiP! youtu.be/_ayaath5-50?...

Check out Kit wearing a Pseudorandom Ensemble T-shirt! You too could buy one, from pseudorandom-ensemble.teemill.com

Here’s a zoomed in version in case you wanted to better see the band names.

My Mathstonbury T-shirt arrived from my friends in The Pseudo Random Ensemble ‘one of the UK’s top ten mathematically-inspired musical combos’! How many bands to you recognise? Extra points for the maths connection. pseudorandom-ensembl...

This month's #MathsAnimationTMiP deadline is 15th September - if you can make a video showing how to create an animation of a Hilbert curve being drawn, submit it for our playlist and share your approach! Info and submission link at tmip.uk/animation

I reviewed the @prensemble.bsky.social gig at #TMiP25 for the Aperiodical: aperiodical.com/2025/09/revi... #music #maths #MathsToday

Announcing our infographic competition, Graph Craft! Thanks to a grant from #MathsWeekScot @mathsweek.scot we are delighted to launch our infographic competition for students aged 11-16 in #Scotland. Students can win a variety of book bundles - closes on 10th October. Submit here: bit.ly/4n9Aczn

This show was so much fun! Hard to believe it was only 2 years ago that I did a lightning talk at @tmip.bsky.social entitled 'Do you wanna be in a band with me?' Now I have a wonderful community of people who love making maths music (most not pictured here). More to come soon, online and in person.

I didn't learn my lesson. Today's lunch featured cinnamon-flavoured hummus. Not what I was aiming for, but it was actually quite nice.

The MathsJam Gathering 2025 is now open for booking! We'll be at a new venue - Kents Hill Park, in Milton Keynes - on 22-23 November 2025. Tickets and more info at mathsjam.com/gatheri...

The prompt for this month's #MathsAnimationTMiP is "create an animation showing a Hilbert Curve filling a square". Can you do it? What software would you use? It can be as high- or low-tech as you like! Join in and submit at tmip.uk/animation

Join me later for another #MathsAnimationTMiP live stream, where we will shove a poor Pikachu across the screen!

My video for #MathsAnimationTMiP July: Create an animation showing that a reflection followed by another reflection is equivalent to a rotation. youtu.be/wFdlrn-kzsg Find out more and join in at www.talkingmathsinpublic.uk/animation/

CALLING ALL CROCHET GEEKS AND GRANNIES Do you want to crochet something that ends up in a mathematical art exhibit in Paris* next summer? Join the project at www.grannylifecrochet.com * We will find out in September if the project makes it into the Paris exhibit

This sounds wonderful!

The compilation video for June's @tmip.bsky.social Animation Generation Collaboration Compilation is live! There were some lovely entries this month, and some techniques and software that are new to the collaboration. Thank you to everyone who took part! youtu.be/kri1aDjsgbo?... #MathsAnimationTMiP
