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


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

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

Form follows functions

Functions are fun to play with. Just watch kids sitting around a graphing calculator. The more math you know the more fun you can have. Even better with the power of computers you… Continue reading

Handcrafting the digital: Wedding rings

This is cross posted on Brian Lockyear’s Gnarly Architecture blog. Those interested in the intersection of the technical and artistic worlds (probably a majority given the topics of this blog) should take a… Continue reading

Permutations, weaving and wedding rings

For a strange variety of reasons, even though we have just celebrated our third anniversary the process of our wedding has only really just been completed. In particular I only recently got a… Continue reading

Have we ever lost mathematics?

If you study the history of modern mathematics one of the recurring themes is the collapse of the foundations. A realisation that the assumptions underlying a topic were not as strong as might… Continue reading

The 2×1 rectangle and Domes

Next week I am going to be at the Gathering for Gardner, an exciting meeting of mathematicians, magicians, puzzlers and others inspired by the life and work of Martin Gardner. This post is… Continue reading

Prime Phyllotaxis Spirals

The phyllotaxis spiral is one of the classical forms of mathematics, and there is a wonderland of resources available online both images and explanations. The basic idea is to put points round in… Continue reading

2+2 = 1? Patterns in Modular arithmetic

When someone is talking about the absolute truth of mathematics and declares that once you have defined 2 and +, then 2+2 must equal 4, there is a slightly glib response: but 2+2… Continue reading

Hyperboloid lighting

The hyperboloid of one sheet is a fascinating shape that turns up in many places. It was therefore a great example to take for a test of thearender which I recently purchased. This… Continue reading
