Castrovalva (M. C. Escher)
''Castrovalva'' is a lithograph print by the Dutch artist M. C. Escher, first printed in February 1930. Like many of Escher's early works, it depicts a place that he visited on a tour of Italy. It depicts the Abruzzo village of Castrovalva, which lies at the top of a sheer slope. The perspective is toward the northwest, from the narrow trail on the left which, at the point from which this view is seen, makes a hairpin turn to the right, descending to the valley. In the foreground at the side of the trail, there are several flowering plants, grasses, ferns, a beetle and a snail. In the expansive valley below there are cultivated fields and two more towns, the nearest of which is Anversa degli Abruzzi, with Casale in the distance. In popular culture *In 1982 the name " Castrovalva" was used in a story in the BBC television series '' Doctor Who''. The storyline also relied heavily on recursion, a favorite theme in Escher's later and more famous works, and used ideas taken from '' ...

Lithography
Lithography () is a planographic method of printing originally based on the immiscibility of oil and water. The printing is from a stone ( lithographic limestone) or a metal plate with a smooth surface. It was invented in 1796 by the German author and actor Alois Senefelder and was initially used mostly for musical scores and maps.Meggs, Philip B. A History of Graphic Design. (1998) John Wiley & Sons, Inc. p 146 Carter, Rob, Ben Day, Philip Meggs. Typographic Design: Form and Communication, Third Edition. (2002) John Wiley & Sons, Inc. p 11 Lithography can be used to print text or images onto paper or other suitable material. A lithograph is something printed by lithography, but this term is only used for fine art prints and some other, mostly older, types of printed matter, not for those made by modern commercial lithography. Originally, the image to be printed was drawn with a greasy substance, such as oil, fat, or wax onto the surface of a smooth and flat limestone pl ...

Recursion
Recursion (adjective: ''recursive'') occurs when a thing is defined in terms of itself or of its type. Recursion is used in a variety of disciplines ranging from linguistics to logic. The most common application of recursion is in mathematics and computer science, where a function being defined is applied within its own definition. While this apparently defines an infinite number of instances (function values), it is often done in such a way that no infinite loop or infinite chain of references ("crock recursion") can occur. Formal definitions In mathematics and computer science, a class of objects or methods exhibits recursive behavior when it can be defined by two properties: * A simple ''base case'' (or cases) — a terminating scenario that does not use recursion to produce an answer * A ''recursive step'' — a set of rules that reduces all successive cases toward the base case. For example, the following is a recursive definition of a person's ''ancestor''. One's anc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ascending And Descending
''Ascending and Descending'' is a lithograph print by the Dutch artist M. C. Escher first printed in March 1960. The original print measures . The lithograph depicts a large building roofed by a never-ending staircase. Two lines of identically dressed men appear on the staircase, one line ascending while the other descends. Two figures sit apart from the people on the endless staircase: one in a secluded courtyard, the other on a lower set of stairs. While most two-dimensional artists use relative proportions to create an illusion of depth, Escher here and elsewhere uses conflicting proportions to create the visual paradox. ''Ascending and Descending'' was influenced by, and is an artistic implementation of, the Penrose stairs, an impossible object; Lionel Penrose had first published his concept in the February 1958 issue of the ''British Journal of Psychology''. Escher developed the theme further in his print ''Waterfall A waterfall is a point in a river or stream wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Doctor Who
''Doctor Who'' is a British science fiction television series broadcast by the BBC since 1963. The series depicts the adventures of a Time Lord called the Doctor, an extraterrestrial being who appears to be human. The Doctor explores the universe in a time-travelling space ship called the TARDIS. The TARDIS exterior appears as a blue British police box, which was a common sight in Britain in 1963 when the series first aired. With various companions, the Doctor combats foes, works to save civilisations, and helps people in need. Beginning with William Hartnell, thirteen actors have headlined the series as the Doctor; in 2017, Jodie Whittaker became the first woman to officially play the role on television. The transition from one actor to another is written into the plot of the series with the concept of regeneration into a new incarnation, a plot device in which a Time Lord "transforms" into a new body when the current one is too badly harmed to heal normally. ...

Castrovalva (Doctor Who)
''Castrovalva'' is the first serial of the 19th season of the British science fiction television series '' Doctor Who'', which was first broadcast in four twice-weekly parts on BBC1 from 4 to 12 January 1982. It was the first full serial to feature Peter Davison as the Fifth Doctor. The title is a reference to the lithograph '' Castrovalva'' by M. C. Escher, which depicts the town Castrovalva in the Abruzzo region, Italy. In the serial, the alien time traveller the Doctor is led into a trap when his arch-enemy the Master ( Anthony Ainley) uses the mathematical abilities of the Doctor's travelling companion Adric ( Matthew Waterhouse) to create Castrovalva, a town whose dimensions fold in on itself. This was the first Doctor Who story not to air on Saturday nights. With Peter Davison taking over as the Doctor, the BBC chose to move Doctor Who from its usual Saturday night slot, where it had been since Doctor Who launched in November 1963.
