    I’m going to run πkm every day in March

    By Katie Steckles. Posted February 23, 2018

    Running shoes

    Inspired by the BBC’s Sport Relief fundraising campaign, I’ve decided to set myself a vaguely mathematical running challenge. My current routine does involve a little running, but nothing serious, so I’ve given myself a bar to aim for that’s both vaguely achievable, and completely irrational. I’ll aim to run π kilometres (or as close as…

    Taming the AGM

    By Philipp Reinhard. Posted February 21, 2018

    3D plot of the function

    This post is in response to Peter’s post introducing the Approximate Geometric Mean. The approximate geometric mean $\mathrm{(AGM)}$ is a nice approximation of the geometric mean $\mathrm{(GM)}$, but it has some quirks as we will see. After a discussion at the MathsJam gathering, I was intrigued to find out how good an approximation it is.…

    Approaching Fermi problems with the approximate geometric mean

    By Peter Rowlett. Posted February 16, 2018

    Man talking on the phone

    I gave a talk on Fermi problems and a method for approaching them using the approximate geometric mean at the Maths Jam gathering in 2017. This post is a write up of that talk with some extras added in from useful discussion afterwards. Enrico Fermi apparently had a knack for making rough estimates with very…

    Ten years and eight days

    By Peter Rowlett. Posted February 8, 2018

    On 31st January 2008, I gave my first lecture. I was passing my PhD supervisor in the corridor and he said “there might be some teaching going if you fancy it, go and talk to Mike”. And that, as innocuous as it sounds, was the spark that lit the flame. I strongly disliked public speaking,…

    Gerrymandering Gives Mathematics’s Moon a Day in the Sun

    By Samuel Hansen. Posted February 4, 2018

    If you pay attention to United States politics you have probably noticed that mathematics is currently enjoying a rare moment of relevance. You probably also know this is not happening because all of a sudden politicians have decided that mathematics is clearly the coolest thing in the world, even though it clearly is, but instead…

    Review: Closing the Gap, by Vicky Neale

    By Colin Beveridge. Posted February 2, 2018

    Did you read Cédric Villani’s Birth of a Theorem? Did you have the same reaction as me, that all of the mentions of the technical details were incredibly impressive, doubtless meaningful to those in the know, but ultimately unenlightening? Writing about maths, especially deep technical maths, so that a reader can follow along with it…
