|Lu's mathematical and historical research has revealed new insights in medieval Islamic quasicrystalline tilings and the earliest machines, such as the one he suggests precisely interconverted the linear and rotational motion responsible for the distinctive spiral grooves carved on ritual jade rings buried in tombs dating from China's Spring and Autumn period (771–475 BC) -- carvings that follow a precise mathematical form described by the spiral of Archimedes, 300 years before he lived.|
