- I wrote this note in response to this MathOverflow question. Shortly afterwards I realised that Mohammad Reza Darafsheh had beaten me to it, so this note is unlikely to be published.
- Marcus Hum, Dömötör Pálvölgyi and I answered the MathOverflow question Is there always a maximum anti-rectangle with a corner square?. Our answer was cited in this economics(!) paper.
- A letter in the Guardian;
- An article on free journals in mathematics. The article gives some of the reasons why I, and many others, choose to publish in low-cost or free journals.
I am an associate member of, and the webmaster for, the European Mathematical Society’s Commission for Developing Countries.
And finally, two talks that I’ve given at Banff:
