Really sad to hear that designer Issey Miyake has passed away. His work, using folding (Pleats Please) and seamless design (A-POC, a piece of cloth), are inspiring and exquisite examples of mathematics brought to life. And all that beauty having survived Hiroshima as a child.

Delighted to be launching, Sharp Forms, a @TarquinGroup eBook in memory of John Sharp at the @BridgesMathart conference at Aalto University

Polyhedron-based artworks in the Bridges 2022 Art Exhibition by, clockwise from top left, Ulrich Mikloweit, Josep Rey Nadal, Stefano Arrighi, and Martin Levin.

Not what I was expecting when @NadavDrukker mentioned ‘throwing a torus is a lot of fun’! 😃

Fortunate to be at the @BridgesMathart conference at Aalto University - kicked off by Daina Taimina sharing her 25 year journey crocheting hyperbolic surfaces …

If you can get to Manchester on Saturday 9th July, don’t miss this amazing free opportunity to learn about Realistic Mathematics Education and the wonderful Key Stage 3 classroom resources at https://t.co/bSJ4xnqVjq ✨ Look forward to seeing you there! 🙂

For those who like Wordle and would also like answers from a mathematical lexicon, try Numble! https://t.co/WTyEAvE32n A free variant🙂by @OUMathsStats colleague @RBrignall. Could be a nice English-maths starter in classrooms!

Earlier this week, reflective moments and the most glorious of sunsets at the wake to celebrate the wonderful life of @RealLateStarter 🙏🏽 (the world makes little sense when someone so kind, generous and with so much to share is prematurely taken away)

Devastating news about Professor Uwe Grimm @reallatestarter. Amazing mathematician, teacher, mentor, colleague, communicator and evangelist for mathematics and learning. I had the privilege of working with him (and @Gelada and others) on the 2009 RS Summer Exhibition on Tilings

Climate crisis, ongoing pandemic, rising cost of living, problems with energy, housing, education and work. Racism, sexism, xenophobia, violence. But what do we want, what do we really really want …

Congratulations to @MathsWorldUK on the launch of @MathsCityLeeds! 🎉Amazing work!! 👏

First day in my new office. Don’t have my name on the door but that’s a plus! 😊

Making maths with Morph and Chas! Tying a 3-lead 4-bight Turk's Head turban for the giraffe😇

Making maths with Morph and Chas?🙃Recently they've been having a go at looping, inspired by the amazing basket-weavers at https://t.co/VgrP38APUX

In case anyone's interested in teaching mathematics to maths+education (and maths+sport) undergraduates! Can vouch that Lincoln is a wonderful and friendly place to live in🙂and BGU has a lovely, cosy campus.

Mathematical Literacy multiple choice test for leading Ofqual/DfE/UK government: If the Ofqual grading model got a THIRD of the grades WRONG when applied to the 2019 data, then, for 2020, it will a) maintain standards b) be fair c) engender confidence d) all of the above.

A more significant error in our system is a failure of imagination in expecting exam-based snapshots to give meaningful measures. If anything needs moderating (or certification!), it is our search for certitude in grades, rather than spending more time/effort engaging with people

Numbers come with error bars🙄‘Living rigorously with uncertainty’ doesn’t mean imposing past years’ grade distributions on the current cohort based on their demographics, but staying with teacher estimates and making due allowance for variation/error.
