Quasiregular dynamics

With Alastair Fletcher, I wrote some code for producing images of Mandelbrot and Julia sets for quasiregular mappings.

Quasi-empirical formalism and rationality

Note: I wrote this in May 2003. It's unfinished but still of some interest I think.

Philosophy of Maths seminar

I've been interested in the philosophy of maths for quite a long time. In the last year of my PhD I started writing a pair of seminars on the subject to be given at the Maths department at the University of Warwick. Unfortunately, writing up my thesis got in the way and I never got round to writing the second part.

An introduction to complex numbers

This is an article for NRICH. It introduces the topic of complex numbers for mathematically inclined school children of ages 15 or 16 and up, in a way which resembles the way university maths is taught rather than the way school maths is taught, with less emphasis on rote learning and calculation and more emphasis on the intuition, abstraction and creativity required for higher maths. For this reason, it may be more difficult than a school level introduction, but I think that those interested in studying maths at university would benefit from the change in style.

An introduction to Galois theory

This is an article for NRICH. It introduces the topic of Galois theory at the level of a good 17 or 18 year old school student student. The two primary motivations for studying it that are given are solving equations by radicals and geometric constructibility proofs.
