  2. Wang tile - Wikipedia

    en.wikipedia.org/wiki/Wang_tile

    Wang tiles have been used for procedural synthesis of textures, heightfields, and other large and nonrepeating bi-dimensional data sets; a small set of precomputed or hand-made source tiles can be assembled very cheaply without too obvious repetitions and periodicity. In this case, traditional aperiodic tilings would show their very regular ...

    The Sonneborn–Berger score is the most popular tiebreaker method used in Round Robin tournaments.However in contrast to Swiss tournaments, where such tiebreaker scores indicate who had the stronger opponents according to final rankings, in Round Robin all players have the same opponents, so the logic is a lot less clear-cut.

    Robert Berger (born 1938) is an applied mathematician, known for discovering the first aperiodic tiling [1] using a set of 20,426 distinct tile shapes. Contributions to tiling theory [ edit ]

  5. Aperiodic tiling - Wikipedia

    en.wikipedia.org/wiki/Aperiodic_tiling

    An einstein (German: ein Stein, one stone) is an aperiodic tiling that uses only a single shape. The first such tile was discovered in 2010 - Socolar–Taylor tile, which is however not connected into one piece. In 2023 a connected tile was discovered, using a shape termed a "hat".

  6. Texture (geology) - Wikipedia

    en.wikipedia.org/wiki/Texture_(geology)

    In geology, texture or rock microstructure [1] refers to the relationship between the materials of which a rock is composed. [2] The broadest textural classes are crystalline (in which the components are intergrown and interlocking crystals), fragmental (in which there is an accumulation of fragments by some physical process), aphanitic (in which crystals are not visible to the unaided eye ...

  7. Stonewall (solitaire) - Wikipedia

    en.wikipedia.org/wiki/Stonewall_(solitaire)

    Stonewall is a solitaire card game using a deck of 52 playing cards. It is probably thus named because the player seems to break down walls in exposing more of the face-down cards. Its tableau is similar to that of Flower Garden with its beds as columns, and it is considered a variant of Flower Garden. Chances of winning are low, especially ...

    Igneous rock, with gray groundmass and white phenocrysts marked. Orthoclase phenocrysts within a finer-grained matrix of a granite porphyry. The matrix or groundmass of a rock is the finer-grained mass of material in which larger grains, crystals, or clasts are embedded.
