In which I attempt to explain some of the ideas behind the h-principle.
Mathematics, mathematicians, philosophy
In December 2016 I gave a talk to secondary school students about mathematics and mathematical philosophy.
The story of a paradox
My story of Bertrand Russell, given at The Laborastory, a monthly science storytelling event in Melbourne.
Riddle. Mystery. Enigma.
I appear in a rather excellent and fun episode of the ABC Radio National program Radiotonic.
Why your calculator is a weapon
I gave a talk about the Defence Trade Cooperation Act, encryption, and number theory, as part of the Monash University LunchMaths seminar series, in August 2015. Slides are available.
Every world in a grain of sand: John Nash’s astonishing geometry
After the recent tragic death of John Forbes Nash Jr, many tributes have been paid to this great mathematician, who was made famous by the movie “A Beautiful Mind”, and much has been said about his work on game theory. But less has been said about Nash’s other mathematical achievements.

You might not think that an academic computer science course could be classified as an export of military technology. But under the Defence Trade Controls Act – which passed into law in April, and will come into force next year – there is a real possibility that even seemingly innocuous educational and research activities could fall foul of Australian defence export control laws.

The Australian government may have classified your calculator — and phone, and computer, and every electronic device you own — as military weapons.
The Lost Art of Integration Impossibility
Integration is less a science and more an art form. It high time we shed some light on this lost art.
To mathematics champions
In November 2014, I spoke at the Victorian prize ceremony for the Australian Mathematics Competition.
