The Naked Scientists Podcast has released an episode on the Clay Millennium Prize Problems, titled ‘The Seven Million Dollar Maths Mystery’. The episode description is:
This week, we’re investigating the Millennium Prize Problems – a set of mathematical equations that, if solved, will not only nab the lucky winner a million, but also revolutionise the world. Plus, the headlines from the world of science and technology, including why screams are so alarming, how fat fish help the human fight against flab, and what’s the future of money?
Better yet, the episode includes a contribution from our very own Katie Steckles talking topology, Poincaré and Perelman.
The episode is available to listen or download as a podcast or, less conveniently, at 5am tomorrow on Radio 5 Live (or later on iPlayer). Not a listener? Read a transcript.
I was invited to contribute to a special issue of The Mathematics Enthusiast on ‘Risk – Mathematical or Otherwise‘, guest edited by Egan J Chernoff. I wrote about the Maths Arcade and programming strategies for a game we play there called Quarto. Really, I was sketching an outline of an idea to encourage student project work.
My title is ‘Developing Strategic and Mathematical Thinking via Game Play: Programming to Investigate a Risky Strategy for Quarto‘ and the abstract is below.
Crossing campus this afternoon, a student whose exam is later this week asked me “when you ask a real-world question on the exam and you want us to solve an ODE, can we just do it using formula we memorised from A-level physics?” Like what? “Like with one of the distance questions we might just use $v^2 = u^2 + 2as$.” I said that if they were relying on a result we didn’t use in the module and that they hadn’t proven, this would be a problem.
In the latest Taking Maths Further podcast (Episode 19: Computer games and mechanics), we had a puzzle that we say could be answered roughly, but the precise answer 23.53 (2 d.p.) required a little calculus. On Twitter, @NickJTaylor said
In the excellent $\pi$ approximation video, Katie Steckles asked for $\pi$ approximations. I teach a first year techniques module (mostly calculus and a little complex numbers and linear algebra). This year I have changed a few bits in my module; in particular I gave some of my more numerical topics to the numerical methods module and took in return some of the more analytic bits from that module. This gives both modules greater coherence, but it means I have lost one of my favourite examples, from the Taylor series topic, which uses a Maclaurin series to approximate $\pi$.
It’s time for our traditional trawl through the New Years Honours list for mentions of “mathematics”, hoping that better-informed readers will fill in the people this crude method has missed. I’ve found the following names:
An obituary has been published in The Guardian for Ivor Grattan-Guinness, historian of mathematics and logic, who died of heart failure on 12th December 2014. This begins by explaining that when Ivor became interested in the history of mathematics in the 1960s,
it was an area of study widely considered to be irrelevant to mathematics proper, or something that older mathematicians did on retirement. As an undergraduate at Oxford, he found that mathematics was presented drily, with no inkling of the original motivations behind its development. So Ivor set himself the task of asking “What happened in the past?” — as opposed, he said, to taking the heritage viewpoint of asking “How did we get here?”

I have a paper published online-first by BSHM Bulletin: Journal of the British Society for the History of Mathematics. This means it is online and will be in an upcoming issue.
My title is: ‘The unplanned impact of mathematics’ and its implications for research funding: a discussion-led educational activity.
