Doctor Who

Doctor Who is a British science-fiction television programme produced by the BBC from 1963 to the present day. The programme depicts the adventures of the Doctor, a Time Lord—a space and time-travelling humanoid alien. He explores the universe in his TARDIS, a sentient time-travelling space ship. Its exterior appears as a blue British police box, which was a common sight in Britain in 1963 when the series first aired. Accompanied by companions, the Doctor combats a variety of foes, while working to save civilisations and help people in need.

The show is a significant part of British popular culture, and elsewhere it has become a cult television favourite. The show has influenced generations of British television professionals, many of whom grew up watching the series. The programme originally ran from 1963 to 1989. There was an unsuccessful attempt to revive regular production in 1996 with a backdoor pilot, in the form of a television film. The programme was relaunched in 2005 by Russell T Davies, who was showrunner and head writer for the first five years of its revival, produced in-house by BBC Wales in Cardiff. The first series of the 21st century featured Christopher Eccleston in the title role and was produced by the BBC. Series two and three had some development money contributed by the Canadian Broadcasting Corporation (CBC), which was credited as a co-producer.Doctor Who also spawned spin-offs in multiple media, including Torchwood (2006–2011) and The Sarah Jane Adventures (2007–2011), both created by Russell T Davies; K-9 (2009–2010); and a single pilot episode of K-9 and Company (1981). There also have been many spoofs and cultural references to the character in other media.

Plot

Synopsis

The Doctor takes Clara, and her nanny charges, Angie and Artie, to Hedgewick's World of Wonders, an extraterrestrial theme park. They find the park is closed down and under military occupation. The Doctor convinces Captain Alice Ferring that he is an ambassador working for their missing Emperor, and is allowed to stay. They encounter a man named Webley, hiding from the troops, and he shows the visitors his "Webley's World of Wonders", a collection of oddities from across the universe. Deactivated Cybermen are harmless museum pieces, because Cybermen were defeated and exterminated a thousand years ago. He promises a silver "Imperial penny" for defeating one converted into a chess-playing machine, but they discover the operator is really Porridge, a chess champion with dwarfism.

Silver

Silver is the metallic element with the atomic number 47. Its symbol is Ag, from the Latin argentum, from a PIE root reconstructed as *h₂erǵ-, "grey" or "shining". A soft, white, lustrous transition metal, it possesses the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. The metal occurs naturally in its pure, free form (native silver), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. Most silver is produced as a byproduct of copper, gold, lead, and zinc refining.

Silver has long been valued as a precious metal. More abundant than gold, silver metal has functioned in many premodern monetary systems as coinable specie, sometimes even alongside gold. Its purity is typically measured on a per-mille basis; a 94%-pure alloy is described as "0.940 fine". In addition, silver has numerous applications beyond currency, such as in solar panels, water filtration, jewelry and ornaments, high-value tableware and utensils (hence the term silverware), and also as an investment in the forms of coins and bullion. Silver is used industrially in electrical contacts and conductors, in specialized mirrors, window coatings and in catalysis of chemical reactions. Its compounds are used in photographic film and X-rays. Dilute silver nitrate solutions and other silver compounds are used as disinfectants and microbiocides (oligodynamic effect), added to bandages and wound-dressings, catheters and other medical instruments.

Nightmare

A nightmare is an unpleasant dream that can cause a strong emotional response from the mind, typically fear but also despair, anxiety and great sadness. The dream may contain situations of discomfort, psychological or physical terror. Sufferers often awaken in a state of distress and may be unable to return to sleep for a small period.

Nightmares can have physical causes such as sleeping in an uncomfortable or awkward position, having a fever, or psychological causes such as stress, anxiety, and as a side effect of various drugs. Eating before going to sleep, which triggers an increase in the body's metabolism and brain activity, is a potential stimulus for nightmares. Recurrent nightmares may require medical help, as they can interfere with sleeping patterns and cause insomnia.

Etymology

The word "nightmare" derives from the Old English "mare", a mythological demon or goblin who torments others with frightening dreams. Subsequently, the prefix "night-" was added to stress the dream-aspect. The word "nightmare" is cognate with the older German term Nachtmahr.
