An einstein, from the German ein Stein, one stone, is a single shape that tiles the plane but never repeats. Since the 1960s, such tilings had always needed sets of shapes, from Robert Berger’s 20,426 down to Roger Penrose’s two. Then Smith, a retired print technician in East Yorkshire, found one in November 2022: the hat, eight kites from a hexagonal grid. The blue are mirror images, outnumbered by the golden ratio to the fourth power; the yellow meet in threes and branch like trees.
Computed, not drawn: every mark on the plate comes from the mathematics or from real data, and the type is set from the same files that go to the printer.
The tiling is generated with a port of Craig S. Kaplan’s hatviz (BSD 3-Clause licence, © 2023 Craig S. Kaplan).
