and chemistry . In particular, the celebrated Penrosetiling is an example of an aperiodic substitution tiling. History In 1973 and 1974, Roger Penrose discovered a family of aperiodic tilings, now called Penrosetiling s. The first description was given in terms of matching rules treating the prototiles ...In geometry, a tile substitution is a useful method for constructing highly ordered Tessellation tiling s. Most importantly, some tile substitutions generate aperiodic tiling s, which are tilings whose prototiles do not admit any tiling with translational symmetry . The most famous of these are the Penrosetiling s. Introduction A tile substitution is described by a Set mathematics set of prototiles ... math . Intuitively, higher and higher iterations of tile substitution produce a tiling of the plane called a substitution tiling . Some substitution tilings are Periodic function periodic , defined as having translational symmetry . Among the nonperiodic substitution tilings are some aperiodic tiling s, those whose prototiles cannot be rearranged to form a periodic tiling usually if one requires in addition some matching rules . A simple example that produces a periodic tiling has only one prototile ... how this procedure yields a substitution tiling of the entire Plane mathematics plane . A mathematically ... aperiodic tiling s, which are objects of interest in many fields of mathematics , including automata ... a tessellation tiling of the plane, but cannot do so periodically, uses a construction that can be cast as a substitution tiling of the prototiles.

Unreferenced date December 2009 Puzzles Tiling puzzles are puzzle s involving two dimensional packing problem s in which a number of flat shapes have to be assembled into a larger given shape without overlaps and often without gaps . Some tiling puzzles ask you to dissect a given shape first and then rearrange the pieces into another shape. Other tiling puzzles ask you to dissect a given shape while fulfilling certain conditions. The two latter types of tiling puzzles are also called dissection puzzle s. Tiling puzzles may be made from wood , metal , Corrugated fiberboard cardboard , plastic or any other sheet material. Many tiling puzzles are now available as computer game s. Tiling puzzles have a long history. Some of the oldest and most famous are jigsaw puzzle s and the Tangram puzzle.

lunar crater data latitude 53.1 N or S S longitude 132.6 E or W W diameter 38 km depth Unknown colong 132 eponym Reinhold Tiling Tiling is a small, undistinguished Impact crater crater on the Far side Moon far side of the Moon . It is located just over one crater diameter to the north northeast of the prominent crater Fizeau crater Fizeau . The outer rim of Tiling is worn and rounded, with a small craterlet along the western edge. The interior floor is relatively level and featureless, with only a small craterlet along the eastern edge and inner wall. To the north northeast of Tiling and running towards the northeast is a broken groove in the surface. Several such features lie in the irregular terrain to the east and northeast of Tiling, and these are all radial to the Mare Orientale impact basin farther to the northeast. Satellite craters By convention these features are identified on lunar maps by placing the letter on the side of the crater mid point that is closest to Tiling. class wikitable width 25 style background eeeeee Tiling width 25 style background eeeeee Latitude width 25 style background eeeeee Longitude width 25 style background eeeeee Diameter align center C align center 50.4 S align center 129.7 W align center 21 km align center D align center 52.0 S align center 131.2 W align center 34 km align center F align center 52.3 S align center 129.0 W align center 17 km align center G align center 53.0 S align center 128.6 W align center 14 km References Lunar crater references Category Impact craters on the Moon Moon crater stub fa ... more details
In geometry , a shape is said to be anisohedral if it admits a tessellation tiling , but no such tiling is isohedral tile transitive that is, in any tiling by that shape there are two tiles that are not equivalent under any symmetry of the tiling.
