The English language draws a terminological distinction (which does not exist in every language) between translating (a written text) and interpreting (oral or signed communication between users of different languages) under this distinction, translation can begin only after the appearance of writing within a language community.Ī translator always risks inadvertently introducing source-language words, grammar, or syntax into the target-language rendering. Translation is the communication of the meaning of a source-language text by means of an equivalent target-language text. Third and fourth squares show the finished translation being brought to, and then presented to, the King. First square shows his ordering the translation second square, the translation being made. Geodesic domes are both theoretical 3D geometric constructs and built structures.King Charles V the Wise commissions a translation of Aristotle. Chemical discoveries show that certain carbon molecules take the shape of a truncated isocahedren. Tessellations appear in various scientific and engineering disciplines. Scientists have determined that beehives are composed of hexagons because that is the most efficient way for bees to construct their homes. These designs, which can contain representational elements, are often called diaper designs.Īlthough often considered an art or design application, tessellations can be found in nature, as in the patterns of snowflakes, honeycombs, and cracks in dry earth.
Many contemporary artists apply tessellations in their work. Many of his designs “morph” different shapes, such as hexagons evolving into creatures.
Escher is famed for his tessellations composed of horses, butterflies, birds, and imaginary creatures (which in the 1990s formed the basis of a popular line of upholstery fabrics!). Tessellations are particularly prominent in Islamic art, which forbids representational images of God therefore, its designs favor abstract forms with mathematical underpinnings.Īlthough tesserae often consist of abstract shapes, primarily symmetrical rectangles, hexagons, octagons, and other polygons, they also can consist of figurative elements, as in the work of artists like Kolomon Moser (1868-1918) and M.C. This is an ancient technique that you can see in buildings and wall murals in Greece, Italy, Turkey, India, and many other countries. These tesserae normally are cut into geometric shapes that fit together perfectly in either simple or complex designs in a seemingly infinite pattern while providing continuous surface coverage. In design and architecture, tessellation refers to the paving of walls, floors, or other surfaces with a pattern of small tiles (tesserae) made of ceramics, glass, metal leaf, stone, or other materials. Tessellations have practical applications in many realms, from art and architecture to science, technology, and production. Escher produced well-known examples of such tilings, such as his graphic of birds that morph into triangles. Non-periodic (aperiodic) tilings have no regular, repetitious patterns but rather evolve as they expand over a plane.
Such forms can combine combinations of shapes only five are regular polyhedra (i.e. Tessellations can take 3 dimensional forms as in truncated octahedrons and in geodesic domes. Often called polyforms, rep-tiles are implicit in such phenomena as the classic illustration of the Golden Mean and the Penrose Tile. Rep-tiles consist of congruent shapes that are rotated to create ever-larger versions of the shaped in an infinite series. Tessellations using two types of polygons. Nine types of semi-regular tessellations exist.įigure 2. For example, a regular hexagon with a 1″ side can line up with a 1″ square. Semi-regular tessellations combine two types of polygons that share a common vertice.
Of these shapes, only the squares line up with one another without requiring rotating or shifting.įigure 1: Tessellations using one type of polygon. These shapes by themselves can fill a surface because their interior angles are exact divisors of 360°. Only three types of regular tessellations exist: triangles, squares, and hexagons. Regular tessellations form patterns consisting of a single shape. Tessellations can be divided into several categories sample subsets include the following: This is a mathematical discipline which has been evolving since the early 17th century and formally recognized in the 19th century. In mathematics, tessellation refers to the study of “tiling” or how regular shapes can be placed to fill an infinite space with no gaps and no overlapping shapes. From these ancient words derive similar terms in various practical applications. The Latin word tessera means cube or die and tessella refers to small squares laid in a mosaic. The word tessellation originates from the ancient Greek word tessares, meaning four or four-cornered.
