quasicrystalline

"By the 15th century the tiled patterns had become extraordinarily complex and a handful of them were what mathematicians today call 'quasicrystalline' designs."

By the 15th century, decorative tile patterns on these masterpieces of Islamic architecture reached such complexity that a small number boasted what seem to be "quasicrystalline" designs, Harvard University's Peter Lu and Princeton University's Paul Steinhardt wrote in the journal Science.

In the 1980s, Steinhardt, a physicist at Princeton, armed with Penrose's insight, found that some chemicals had their atoms arranged in a "quasicrystalline" shape like that of the fivefold grid.

While traveling in Uzbekistan, Lu said, he noticed a 16th century Islamic building with decagonal motif tiling, arousing his curiosity as to the existence of quasicrystalline Islamic tilings.

Emil Makovicky of the University of Copenhagen in Denmark in the 1990s noticed the relationship between these designs and a form of quasicrystalline designs.

The scientists found that by 1453, Islamic architects had created overlapping patterns with girih tiles at two sites to produce near-perfect quasicrystalline patterns that did not repeat themselves.
