# Prime Time

Having seen a mathematical claim in the paper, Katie has found it to be correct (for a change) and dug into what else it implies.

# Stanisław Ulam biopic

There's going to be a biopic of physicist/mathematician Stanisław Ulam, titled Adventures of a Mathematician﻿.

Hollywood seems to be working its way through 20th century mathematicians – off the top of my head, there have recently been biopics of John Nash, Alan Turing, Stephen Hawking and Srinivasa Ramanujan. What I want to know is, when do we get Michael Sheen playing John Horton Conway?

There's some information about Adventures of a Mathematician, starring Jakub Gierszal as Ulam, at ScreenDaily.

# I’m going to run πkm every day in March

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… Read more »

# Taming the AGM

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…. Read more »

# Approaching Fermi problems with the approximate geometric mean

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… Read more »

# Ten years and eight days

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,… Read more »

# Carnival of Mathematics 154

The next issue of the Carnival of Mathematics, rounding up blog posts from the month of January, and compiled by Rachel, is now online at The Math Citadel. The Carnival rounds up maths blog posts from all over the internet, including some from our own Aperiodical. See our Carnival of Mathematics page for more information.
