Most months I go to MathsJam, and most years I’m at the annual MathsJam weekend, and so I have a healthy love of recreational mathematics. This is some of the nonsense which has come from that.
In 2016, I helped Katie Steckles and Matt Parker build the Megapixel, a digital display made out of transparent plastic and red, green and blue OHP markers. This is my writeup and dive into the calibration maths.
In another of Matt's silly projects for Manchester Science Festival, we taught 300 matchboxes to play noughts and crosses.
This is a blogpost exploring just how one arm of a snowflake knows what the others are doing, using cellular automata.
I have also built a gadget for playing with Koch snowflake curvesand one which generates Sierpinski gaskets from random patterns of dots.
During the 2011 referendum on the Alternative Vote, I got quite interested in the maths of voting systems. I wrote this blog post about the rather silly idea that “AV can elect the loser”, and this for the Aperiodical relating the nonsense of voting systems to the nonsense of ThinkMaths’ Grime Dice, which eventually became an item on BBC Radio 4’s Material World.
The Polygonal Number Checker is the best part.
I also helped create the rather silly index for the paperback re-issue.
