Socolar-Taylor aperiodic tile models on Thingiverse

Socolar-Taylor aperiodic tile models on Thingiverse

So the bragging rights I mentioned in Monday’s post about the newly-discovered single shape that tiles the plane aperiodically go to mathematician and artist Edmund Harriss, aka Gelada, who produced these beautiful renderings of the Socolar-Taylor tile in Blender and uploaded printable 3D models to Thingiverse. There’s more info and images on Harriss’s blog, Maxwell’s Demon. [Thanks, Edmund!]

World’s first aperiodic tiling with a single shape

World’s first aperiodic tiling with a single shape

The problem of tiling a plane has fascinated builders and mathematicians alike since time immemorial. At first glance, the task is straightforward: squares, triangles, hexagons all do the trick producing well known periodic structures. Ditto any number of irregular shapes and combinations of them.

A much trickier question is to ask which shapes can tile a plane in a pattern that does not repeat. In 1962, the mathematician Robert Berger discovered the first set of tiles that did the trick. This set consisted of 20,426 shapes: not an easy set to tile your bathroom with.

With a warm regard for home improvers, Berger later reduced the set to 104 shapes and others have since reduced the number further. Today, the most famous are the Penrose aperiodic tiles, discovered in the early 1970s, which can cover a plane using only two shapes: kites and darts.

The problem of finding a single tile that can do the job is called the einstein problem; nothing to do with the great man but from the German for one– “ein”–and for tile–“stein”. But the search for an einstein has proven fruitless. Until now.

Tilt-N-Trap 3D-printed mousetrap

Mark Fuller sent us this video demoing his 3D-printed, humane mousetrap. Love this simple gravity-powered design. Mark says he made the trap with the help of the rapid prototyping class at Pennsylvania College of Technology (www.pct.edu). The device was printed on the Dimension uPrint, in little a under six hours. Tilt-N-Trap (Mouse Trap) on Thingiverse […]
