Mountain Laurel

Mathematical art geometry raised 3D Penrose tiling by Debora Coombs & Duane Bailey at Williams College

Mountain Laurel is one of three recently completed sculptures now on display in the Schow Science Library at Williams College. They show an area of three-dimensional Penrose tiling that continues to infinity in all directions. This ongoing series is a collaboration with my friend computer scientist Duane Bailey who has spent 30+ years investigating Penrose tiling. Our exhibition is called a.periodicity a mathematical term for this curious symmetry.

The sculptures are structurally identical -all precisely the same size and shape. But each is coloured differently according to some aspect of the mathematics. Mountain Laurel provides insight into the relationship between 2D and 3D versions of Penrose tiling.

In two-dimensions Penrose tiling requires two different shapes to construct; a fat rhombus and a skinny rhombus. Although each tile in the sculpture is identical, Mountain Laurel codes them according to the shadow they would project onto a flat surface. Green tiles would project the shadow of a skinny rhombus in 2D. Pink tiles would create the shadow of a fat rhombus in 2D.

In all three sculptures, colour enables us to see unexpected shapes and patterns when the sculpture is viewed from different angles. Mountain Laurel is built from identical rhombi -the tiles are all the same shape – but the composition yields marvelously irregular patterns. Shapes and rhythms appear and disintegrate as you move around the sculpture.

 

The back of the sculpture provided its title Mountain Laurel. Here’s work in progress with binder clips and reverse-engineered clothes pins.

Aperiodic tilings are mathematical models for quasicrystals, physical solids that were discovered in 1982 by Dan Shechtman who subsequently won the Nobel prize for his work in 2011. I’ve also built them in stained glass, with mathematical rules encoded into the surface pattern.

Exhibition of new work at Williams College

This week I hung three newly completed mathematical sculptures in the Schow Science Library at Williams College in Williamstown, Massachusetts. I’m excited to be able to share this new work, made in collaboration with computer scientist Duane Bailey. It’s the first public showing of our series of three-dimensional Penrose tilings. The exhibit is in the Schow Science Library and open extended hours. See Williams College Visitor Guide for location and directions. Contact me if you’d like a tour.

Work in progress on mathematical tiling done during my Artist Residency at MASS MoCA this month. Also models made with computer scientist Duane Bailey this past July. Scroll down this post for construction pics.
