  • Verifying a neat identity: showing a connection between linear algebra and calculus

    My PhD student Nikoleta and I are doing some work relating the Prisoner’s Dilemma to quadratic forms (a linear algebraic generalisation of quadratics) and it’s led me to really come to appreciate a specific identity regarding their derivatives. In this post I’ll describe what the identity is and what it means but also verify it using Python.

  • Fitting ranks to a distribution

    This is a brief blog post to describe how to scale a set of ranks to some distribution using a percentage point function. This is in the category of blog posts of me writing myself a note so that I remember how to do this when I need to.

  • The fallacy of a meritocracy (using game theory)

    Today we hosted Dame Professor Celia Hoyles who gave a talk at the launch event of Cardiff’s new Mathematics Education Research Group (MERG). Amongst many interesting things the topic of the gender imbalance in Mathematics came up. In this post I’ll use a game theoretic model of evolution to describe one aspect of lack of diversity: the fallacy that is a meritocracy.

  • The effect of goats (on the Monty hall problem)

    I’ve just written a 3 page example coursework submission as a demo for my first year students. This is for a course called “Computer for Mathematics” which aims to introduce mathematics students to programming techniques useful to mathematicians (in Python). The particular example I chose to write about is one (of many possibly) generalisation of the Monty Hall problem. I’m rewriting what I did here in case it’s of interest to anyone.
