## Functional Drawing at C&!

Last week I taught at the first (year 0) of C&!, the Camp for Algorithmic Math Play. It was a lot of fun working on mathematical play and games with a group of… Continue reading

## Let them be

In the previous post on curvahedra spheres, we actually missed an interesting collection of curvahedra balls, as we assumed that every face had at least 3 sides. This makes a lot of sense… Continue reading

## Making Spheres

Curvahedra can make all sorts of objects, but some of the most satisfying are spheres, like the classic ball itself (here serving as a Christmas ornament). So what other spheres or near spheres… Continue reading

## The Curve in the Curvahedra

These are Curvahedra pieces:They can hook together to make all sorts of geometric objects. For example, take three pieces and make a triangle (or something triangle like with wiggly edges) Taking a close… Continue reading

## Eigencurves

Linear algebra is one of my favourite areas of mathematics. Its a simplification but you could say that the things that mathematics does well are small numbers and straight lines. The rest is… Continue reading

## Snowflake, Seashell, Star

Alex and I initially met thanks to this blog. He was fact checking for an article that included the Taylor-Socolar aperiodic tiling that I had written up. The general theme of the article… Continue reading

## Data Visualisation, from the World Cup to Drugs in Arkansas

This summer I taught a graduate statistics course in data visualisation at the University of Arkansas. As a final project the students had to find a data set, think of questions you could… Continue reading

## How to Play Like a Mathematician

This is a vague transcript from memory of a talk I gave at Twitter Math Camp 2014. It was a truly energising event, teacher organised peer professional development. Anyone interested in education, whether… Continue reading

## Twelve and the real life problems problem

The number 12, not the most esoteric secret of mathematics. Yet through the under appreciated power of the equals sign it can become 6+6, 3*4, 15-3, 36/3 aall before we add in unusual… Continue reading

## Rational parameterisation of the circle

I really like parametric functions. You take two functions from the reals to the reals and use them to define x and y coordinates of points. For example you can take and you… Continue reading

## The TMC Logo

Collegiate typography parsed into a fractal, with the theme of lots of parts coming together to make the whole. That’s the corporate design spin on the new logo for the Twitter Math Camp,… Continue reading
