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

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 …

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

[OU Maths & Stats @OUMathsStats]

We are deeply saddened by the passing of our dear friend and colleague Professor Uwe Grimm (@reallatestarter). Uwe was an outstanding academic, tutor, PhD and post doc supervisor and mentor to many in the school. He will be sorely missed but his legacy will live on.

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 …

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

[Vinay Kathotia @VinayMaths]

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.

[Lizzie Kimber @LizzieKimber]

I've learned a huge amount in this role and enjoyed working with students at BGU. I'm making a move to focus on research in mathematics education. Please share this link if you know someone who'd be interested in leading the Mathematics Programme at BGU.

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.

[Vinay Kathotia @VinayMaths]

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

[Vinay Kathotia @VinayMaths]

Not sure what the hullabaloo is about teacher-predicted grades being higher than ‘actual’ grades. Given (expected) statistical variation (v) from estimated grades (e), if actual grades were to lie in an interval (e-v, e+v), the range for ‘fair’ estimates would be [e, e+v).

[Vinay Kathotia @VinayMaths]

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.
