It took a while, but I worked out how to make YouTube work on the television. However, the thing I wanted to see is Vimeo.

Geelong Botanical Gardens in Spring sunshine-wildflower meadow of pink everlastings. This is just a small part of it.

Sashiko in action

Latest royalty statement shows there are another 69 copies of A Stitch in Line out in the world, in people's hands. Thank you so much, and happy stitching!

Not sure what to make of the fact that the paragraph instructing my daughter to describe any use she had made of AI in her assignment contained an error that a spell-checker would have picked up.

The cat will not let me pat her, but at least she didn’t hiss at me, which is how she greeted me when I got home from Bridges last year.

Thirty four hours. Still a bus ride, but home.

Frog swallowed.

The website for the 2026 Bridges Conference Exhibition of Mathematical Art, Craft, and Design is now live, featuring the work of more than 150 artists. gallery.bridgesmathart.org/exhibitions/...

The proceedings and the gallery for the exhibition of the Bridges Mathematics and the Arts conference are released. (This is when one starts to get an idea of who will be there - lots of fun!)

Ms 19 and I took the chance to further our joint enjoyment of silo art by tracking down this off-trail singleton in Geelong.

It's World Wide Knit in Public Day, and I joined a small gathering at my local op shop, which hosts a knitting group.

Last year, I made feijoa jam with my father’s large crop. There was a lot of peeling. This year someone else gave me 1.5 kg of small feijoas, so I made a skin-on chutney. Couple of hours in the slow cooker, finished on the stove.

I'm on the hunt for a reference cited in a paper that is about 10 years old, and the author hasn't been super careful about details. When I'm editing, I know authors get frustrated that I check all their page numbers etc. I protect your future reader from my current level of frustration!

Cat seems pleased that we needed a new toaster.

Days like this, I miss Mum the most. (Family wedding.)

New xor pattern generalization dropped! For each pixel (x|y) write x and y in base 3, then add the corresponding digits of x and y mod 3. Here we have purple for f(x,y)%4==0 #mathsky

Son in law not being asked to take family photos in future…but such a proud day.

Two-in-one feijoa

It’s April 30 (in this time zone). Martin, Kerry and I have been working with authors on their submissions for the Bridges conference and the editing is (nearly) done. @msmathcomp.bsky.social

So, so cute. Snow leopard cub.

Learnt a new word today.

Lovely day with Ms 19 seeing part of the zoo that we had not been to before.

It's Anzac Day in Australia. (Think something like Remembrance Day/Armistice Day, although we mark that as well.) One of my favourite mathematics movies is on TV today - Dam Busters. Come for the music, stay for the maths.

Easter

Quick trip to the zoo with Ms 18. This lady was putting on quite a show with rolling and roaring.

D3 symmetry in a kitchen sink (probably original to the house which was built in the seventies). My parents’ home but not the one I grew up in.

Full article: More than just playing: investigating teacher-student interactions in game-based mathematics lessons www.tandfonline.com/doi/full/10.... Just appeared online recently. Games are widely used in mathematics lessons...but how does what the teacher does enhance the learning from a game?

Day ☀️♥️

Ah, it is Wednesday (again)....

Our International Day of Mathematics events includes 2 special magic shows by Tadashi Tokieda at the Chau Chak Wing Museum on Sat 14 & Sun 15 March 12:30 pm 'A magic show' will be for both curious children 🧒 & seasoned scientists alike! 🪄👩‍🔬 🎩 🧮 events.humanitix.com/a-magic-show... #MathSky

My book appeared on the Bookshelf of the Notices of the American Mathematical Society! (September 2025.) www.ams.org/journals/not...

'A world from a sheet of paper' - SMRI's #InternationalDayOfMathematics public lecture by Tadashi Tokieda will be on Fri 13 March Starting from a sheet of paper, explore magic tricks and geometry in this lecture filled with table-top demonstrations 🔗 events.humanitix.com/internationa... #MathSky🧮

During a faculty debate this morning on the topic of using AI to help grade assignments, I pointed out that students should have the right to opt out of having their work uploaded to an LLM (or any external system, like Turnitin). Does anyone know of any cases or laws or policies that support this?

arxiv.org/abs/2602.00178 I've been quiet lately, because I have been writing.

Day 6 of the math-art class I’m leading. The main activities: lunch and share outs with the math and music class, and setting up an art gallery and pairs of our kids each showing their art pieces and doing an art project with 3 kindergartners. Each pair created their own lesson plan! #mathart #mtbos

I started this project twelve years ago, and today I hold the result in my hand. It’s a book that combines bead weaving with math called, “Beading with Algorithms: Cellular Automata in Peyote Stitch.” This book is the first of its kind, a recipe book of algorithms for making pixel art.

Lovely morning picking raspberries at Kinglake Raspberry Farm with Ms 19. It's a bit of a summer tradition for us now. Much later than most years. (Always get a smile from other people's kids who spot a wombat hole, of which there are many, and think that they might spot a wombat.)
