Guest Editors Samar Malek and Chris Williams provide an overview of the aesthetic properties of shell and tension structures, drawing on classical arguments about the relationship between nature, mathematics and architecture. The letter concludes with an introduction to the papers in NNJ 19(3).
The theory of heat flow on a surface shows that any curvilinear quadrilateral can be ‘tiled’ with curvilinear squares of varying size. This paper demonstrates a simple numerical technique for doing this that can also be applied to shapes other than quadrilaterals. In particular, any curvilinear triangle can be tiled with curvilinear equilateral triangles.
