Most visitors to this blog – and, indeed, to my academia.edu profile – come seeking Charles Howard Hinton and his system of cubes. No surprises there. Hinton’s biography is quite something and his work on visualising – or, perhaps more accurately, imagining – the fourth dimension of space was innovative, influential and almost completely out of its time.

The purpose of this post is to update a project I began almost four years ago and am only really now in a position to continue: the construction of a set of Hinton’s cubes, the material demonstration models that anchored his pedagogical enterprise.

Hinton began working with cubes early in his career. The essay ‘On the Education of the Imagination’ (1888) may well have been written before ‘What is the Fourth Dimension?’ was first published in 1880. In this he describes working with a system of cubes with his school students, and he began teaching in 1876. The system is also based on what he termed ‘poiographs’ in a paper presented before the Physical Society in 1878, so it seems likely to have been a foundation stone for his project. Certainly, his proficiency with it was advanced by 1887, when he was able to claim that he’d memorised a cubic foot of his named cubes.

He refined the system of cubes over the course of his career. The system described in A New Era of Thought (1888), taking up the entire second-half of that remarkable, visionary text, described cubes with a different colour and name for each vertex, line and face. Relying on description and line drawings it is, unsurprisingly, fiendishly complicated. By 1904’s The Fourth Dimension he had developed a system of ‘catalogue’ cubes and plates to enable a more step-by-step working through of cubic training. There are also many more and far clearer illustrations in this text, so this is the version I’ve followed.

The first task is to paint the correct number of one inch cubes the correct colours, which are as follows:

Null 16
White 8
Yellow 8
Light yellow 4
Red 8
Pink 4
Orange 4
Ochre 2
Blue 8
Light blue 4
Green 4
Light green 2
Purple 4
Light purple 2
Brown 2
Light brown 1

I used model paints of the kind you use to paint Airfix aeroplanes. As a newbie to this game this process caused me more problems than you might imagine. For example, metallic paints sound exciting in the shop – wooh-hooh, electric pink! – but they are more liquid, don’t necessarily look all that great on wood, and can even look largely indistinguishable from lighter, non-metallic shades. Also, on which side do you rest a painted cube to dry? I never discovered the answer to this gnomic poser so my cubes are slightly messy. But hey! They’re my cubes – and they don’t need to be perfect.

After the set of 81 coloured cubes there are the catalogue cubes. These are coloured to distinguish vertices, lines and faces and the fold-out colour-plate at the front of The Fourth Dimension shows how they should look.

As you can see, painting lines a fifth of an inch proved beyond me, either freehand or using tape to mask off. In the end I decided to print out coloured nets of the cubes onto card and cut these out and tape them together. Again, slightly imperfect, but I think they do the job nicely.

There are also coloured slabs, to aid you in thinking like a plane being, as you will be asked to do in the first chapter of exercises, ‘Nomenclature and Analogies Preliminary to the Study of Fourdimensional Figures’ (pp.136-156). These I printed out on card aswell.

I’m going to break these posts up into a series in case anyone wants to join in so I’ll begin with the exercises in the next post sometime in the next week or so. In the meantime, an observation (owing entirely to Dr. Caroline Bassett who pointed it out to me at Weird Council, the China Mieville conference) that will be useful in understanding what’s to come. If, like me, you have about 50 pairs of 3d glasses sitting around the house because you have to buy a new pair every time you go to the cinema to watch Matt Damon Running Really Fast! 3D!, break a set out and take a squizz at the coloured plate above. Your colour-coded anaglyph glasses will be doing all kinds of funky things to the projection diagrams of cubes. Hinton intuitively recruited a colour-coding system to suggest the qualium of an extra dimension of space, which is kind of how we trick out puny brains into registering three dimensions when we drool at a FLAT screen for 90 minutes watching Matt Damon running really fast.

So, ponder that then get thee to a modelling shop (where the staff will be perfectly used to people using the archaic form of the vocative in that way and will possibly be dressed like hobbits).

Bon chance!
