Maths for the people!

Including introductory talks and articles for undergraduate students, outreach talks at schools, popular articles, and the occasional mathematical comic or poem.

Maths articles for the people
  • Tutte meets Homfly
    I’ll tell you about some extremely clever methods to tell graphs and knots apart, involving polynomials: the Tutte and HOMFLY polynomials. And they’re closely related.
  • Holy h-principle, Batman!
    In which I attempt to explain some of the ideas behind the h-principle.
  • 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.
  • Paranoid defence controls could criminalise teaching encryption
    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 ...
  • Why your calculator (and computer, and phone…) is a weapon
    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.
  • Hyperbolic links
    A set of links I collated about hyperbolic geometry.
  • Quadratic geography, algebraic extreme sports and magical Farey trees
    Published in the Australian Mathematical Society Gazette “Mathellaneous” column.
  • Games with Galois
    In 2004 for the Mathellaneous column of the AustMS Gazette, I wrote an article about games and Galois theory.
  • A Beautiful Sequence
    In 2004, I wrote a recreational article for the Australian Mathematical Society Gazette about one of my favourite sequences.
  • The Exotic Realm of p-adic Numbers
    A perhaps not-so-polished article I wrote for Paradox, the magazine of MUMS, the Melbourne University Mathematics and Statistics Society, as an undergraduate student. A very simple very brief introduction to p-adic numbers.
  • Some Mathematicians Like it Hot: Fourier and Descartes
    A perhaps not-so-polished article I wrote for Paradox, the magazine of MUMS, the Melbourne University Mathematics and Statistics Society, as an undergraduate student.
  • Knot Man!
    Of course the most important part of this webpage is the part devoted to mathematical superhero Knot Man. Known to others as Theodore J. Knott, in times of mathematical emergency, with his topological utility belt and supply of high-energy genus-1 donuts, he becomes Knot Man, Defender of the Mathematical Universe, saving the world from all ...
  • Adventures with Pascal’s triangle and binary numbers
    An article I wrote for Paradox, the magazine of MUMS, the Melbourne University Mathematics and Statistics Society, as an undergraduate student.
  • Mathematical haiku
    As an undergraduate student, I wrote some mathematical haiku.
Maths talks for the people
  • Is the traditional mathematics blackboard lecture dead?
    The Australian Mathematical Society Annual Meeting this year included a public debate on the topic “Is the traditional mathematics blackboard lecture dead?” I was on the affirmative team.
  • Some pure mathematics and consciousness
    In November 2017 I gave a talk to the Monash Consciousness Research Laboratory (Tsuchiya Lab). I talked about some pure mathematical ideas that have appeared in the literature on the frontiers of neuroscience and the study of consciousness — gauge theory, and category theory.
  • Sciencey: Why do earphones get tangled?
    An appearance in Sciencey, a new series from ABC that delivers quick, illuminating answers to some of the strangest questions in the universe. Why do earphones always tangle, and what does this tells us about the universe?
  • The work of Maryam Mirzakhani
    In August 2017 I gave a talk on some of the mathematics of Maryam Mirzakhani, the great Iranian matheamtician, first female Fields Medallist. This was a Monash LunchMaths seminar.
  • Maths week talk at PLC
    I gave an outreach talk to secondary students at PLC about mathematics and mathematicians, talking about, among other things, topology, Maryam Mirzakhani, and billiards, in July 2017. Slides are available.
  • Mathematics, mathematicians, philosophy
    In December 2016 I gave a talk to secondary school students about mathematics and mathematical philosophy.
  • 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.
  • To mathematics champions
    In November 2014, I spoke at the Victorian prize ceremony for the Australian Mathematics Competition.
  • LunchMaths topology, Aug 2014
    I gave an introductory talk on Topology, as part of the Monash University LunchMaths seminar series, in August 2014. Slides are available.
  • LunchMaths hyperbolic geometry, Sep 2013
    I gave an introductory talk on Hyperbolic Geometry, as part of the Monash University LunchMaths seminar series, in September 2013. Slides are available.
