Double Planetoid
''Double Planetoid'' is a wood engraving print by the Dutch artist M. C. Escher, first printed in 1949. Description ''Double Planetoid'' is printed in four colors from four wood blocks. It depicts a Minor planet, planetoid in the shape of a compound of two tetrahedra, interpenetrating each other to form a stellated octahedron. One of the two tetrahedra is entirely covered by architecture, while the other is a wilderness populated by saurian creatures. The planetoid is shown within a circular black field, in diameter. Themes ''Double Planetoid'' is part of a series of Escher's prints from the 1940s and 1950s that depict small polyhedral planets, also including ''Gravitation (M. C. Escher), Gravitation'' (1952) and ''Tetrahedral Planetoid'' (1954), and possibly in the same universe as his print ''Stars (M. C. Escher), Stars'' (1948). It has thematic connections with other Escher prints from the same period that provide simultaneous views of intermingled worlds, including the more ...

Escher In The Palace
Escher in Het Paleis (''Escher in The Palace'') is a museum in The Hague, Netherlands, featuring the works of the Dutch graphical artist M. C. Escher. It is housed in the Lange Voorhout Palace since November 2002. History The museum is housed in the Lange Voorhout Palace, a former royal residence dating back to the eighteenth century. Queen Emma bought the stately house in 1896. She used it as a winter palace from March 1901 until her death in March 1934. It was used by four subsequent Dutch queens for their business offices, until Queen Beatrix moved the office to Paleis Noordeinde.

Tetrahedral Hypothesis
The tetrahedral hypothesis is an obsolete scientific theory attempting to explain the arrangement of the Earth's continents and oceans by referring to the geometry of a tetrahedron. Although it was a historically interesting theory in the late 19th and early 20th century, it was superseded by the concepts of continental drift and modern plate tectonics. The theory was first proposed by William Lowthian Green in 1875. Theory This idea, described as ‘"ingenious" by geologist Arthur Holmes, is now of historical interest only, being finally refuted by that same Holmes (see reference 7). It attempted to explain apparent anomalies in the distribution of land and water on the Earth's surface: *More than 75% of the Earth's land area is in the northern hemisphere. *Continents are roughly triangular. *Oceans are roughly triangular. *The north pole is surrounded by water, the south pole by land. *Exactly opposite the Earth from land is almost always water. *The Pacific Ocean occupies abou ...

Polyhedral Compound
In geometry, a polyhedral compound is a figure that is composed of several polyhedra sharing a common Centroid, centre. They are the three-dimensional analogs of star polygon#Regular compounds, polygonal compounds such as the hexagram. The outer Vertex (geometry), vertices of a compound can be connected to form a convex polyhedron called its convex hull. A compound is a faceting of its convex hull. Another convex polyhedron is formed by the small central space common to all members of the compound. This polyhedron can be used as the core for a set of stellations. Regular compounds A regular polyhedral compound can be defined as a compound which, like a regular polyhedron, is vertex-transitive, edge-transitive, and face-transitive. Unlike the case of polyhedra, this is not equivalent to the symmetry group acting transitively on its flag (geometry), flags; the compound of two tetrahedra is the only regular compound with that property. There are five regular compounds of polyhe ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Puddle (M
A puddle is a very small accumulation of liquid, usually water, on a surface. It can form either by pooling in a depression on the surface, or by surface tension upon a flat surface. Puddles are often characterized by murky water or mud due to the disturbance and dissolving of surrounding sediment, primarily due to precipitation. A puddle is generally shallow enough to walk through, and too small to traverse with a boat or raft. Small wildlife may be attracted to puddles. Natural puddles and wildlife Puddles in natural landscapes and habitats, when not resulting from precipitation, can indicate the presence of a seep or spring. Small seasonal riparian plants, grasses, and wildflowers can germinate with the ephemeral "head start" of moisture provided by a puddle. Small wildlife, such as birds and insects, can use puddles as a source of essential moisture or for bathing. Raised constructed puddles, bird baths, are a part of domestic and wildlife gardens as a garden ornament a ...

Wood Engraving
Wood engraving is a printmaking technique, in which an artist works an image into a block of wood. Functionally a variety of woodcut, it uses relief printing, where the artist applies ink to the face of the block and prints using relatively low pressure. By contrast, ordinary engraving, like etching, uses a metal plate for the matrix, and is printed by the intaglio method, where the ink fills the ''valleys'', the removed areas. As a result, the blocks for wood engravings deteriorate less quickly than the copper plates of engravings, and have a distinctive white-on-black character. Thomas Bewick developed the wood engraving technique in Great Britain at the end of the 18th century. His work differed from earlier woodcuts in two key ways. First, rather than using woodcarving tools such as knives, Bewick used an engraver's burin (graver). With this, he could create thin delicate lines, often creating large dark areas in the composition. Second, wood engraving traditionally use ...

Stars (M
A star is a luminous spheroid of plasma (physics), plasma held together by Self-gravitation, self-gravity. The List of nearest stars and brown dwarfs, nearest star to Earth is the Sun. Many other stars are visible to the naked eye at night sky, night; their immense distances from Earth make them appear as fixed stars, fixed points of light. The most prominent stars have been categorised into constellations and asterism (astronomy), asterisms, and many of the brightest stars have proper names. Astronomers have assembled star catalogues that identify the known stars and provide standardized stellar designations. The observable universe contains an estimated to stars. Only about 4,000 of these stars are visible to the naked eye—all within the Milky Way galaxy. A star's life star formation, begins with the gravitational collapse of a gaseous nebula of material largely comprising hydrogen, helium, and traces of heavier elements. Its stellar mass, total mass mainly determines it ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Gravitation (M
In physics, gravity (), also known as gravitation or a gravitational interaction, is a fundamental interaction, a mutual attraction between all massive particles. On Earth, gravity takes a slightly different meaning: the observed force between objects and the Earth. This force is dominated by the combined gravitational interactions of particles but also includes effect of the Earth's rotation. Gravity gives weight to physical objects and is essential to understanding the mechanisms responsible for surface water waves and lunar tides. Gravity also has many important biological functions, helping to guide the growth of plants through the process of gravitropism and influencing the circulation of fluids in multicellular organisms. The gravitational attraction between primordial hydrogen and clumps of dark matter in the early universe caused the hydrogen gas to coalesce, eventually condensing and fusing to form stars. At larger scales this results in galaxies and clusters, ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
