A paradox is a statement that apparently contradicts itself and yet might be true (or wrong at the same time). Some logical paradoxes are known to be invalid arguments but are still valuable in promoting critical thinking.
Some paradoxes have revealed errors in definitions assumed to be rigorous, and have caused axioms of mathematics and logic to be re-examined. One example is Russell's paradox, which questions whether a "list of all lists that do not contain themselves" would include itself, and showed that attempts to found set theory on the identification of sets with properties or predicates were flawed. Others, such as Curry's paradox, are not yet resolved.
Examples outside logic include the Ship of Theseus from philosophy (questioning whether a ship repaired over time by replacing each of its wooden parts would remain the same ship). Paradoxes can also take the form of images or other media. For example, M.C. Escher featured perspective-based paradoxes in many of his drawings, with walls that are regarded as floors from other points of view, and staircases that appear to climb endlessly.
Paradox (1882–1890) was a British Thoroughbred racehorse and sire. In a career that lasted from October 1884 until October 1885 he ran eight times and won six races. Despite running only twice in 1884, he proved himself to be one of the best two-year-olds of his generation by winning the Dewhurst Plate. In the following year he won five of his six races including the 2,000 Guineas, the Grand Prix de Paris, the Sussex Stakes and the Champion Stakes. His only defeat came when he was narrowly beaten by Melton in the Epsom Derby.
The final phase of the colt's racing career was marked by controversy and recrimination following his withdrawal from the Cambridgeshire Handicap in the autumn of 1885 and he was retired from racing in 1886. Paradox had little opportunity to establish himself at stud, dying in 1890 at the age of eight.
Paradox was a strongly-built bay horse bred by the Graham brothers at the Yardley Stud near Birmingham. He was sired by the 2,000 Guineas runner-up Sterling out of Casuistry, an undistinguished racehorse who had been sold cheaply at the end of her racing career by Lord Rosebery. Casuistry became an important broodmare, being the direct female ancestor of notable thoroughbreds such as Humorist, Royal Palace and Spend a Buck. As a yearling Paradox was bought for 700 guineas by the trainer John Porter on behalf of his associate, Captain Bowling. Porter trained the colt at his stable at Kingsclere.
Paradox is a mini-album released by the Japanese horror punk band Balzac.
Indica is a Finnish pop rock group founded in 2001. Jani Jalonen of Sony Music became interested in the group, and a recording contract was signed 2003. Indica's first album, Ikuinen virta was released in 2004. It has since sold platinum in Finland.
Indica supported Nightwish during their Scandinavian tour 2007 in which they performed English versions of their songs. Tuomas Holopainen of Nightwish produced their next album, Valoissa, while many of the songs employed the orchestral talents of Pip Williams and the literary talents of their lyrics collaborator Rory Winston. The band was also added to the line-up for Nightwish's 2nd half of the Dark Passion Play Tour with Pain.
Johanna Salomaa (vocals, violin), Heini Säisä (bass), Sirkku Karvonen (keyboards), Jenny Julia (guitar) and Laura Häkkänen (drums) founded Indica in 2001. Before this the girls had already spent their entire childhood surrounded by classical music and had also played in a few different band line-ups. In the Christmas of 2002 Indica signed a management contract with Peter Kokljuschin and in 2003 a record deal with SonyMusic, leading to Indica starting work on their debut album.
Indica Records is a Canadian record label based in Montreal, Quebec, founded by rock band Grim Skunk in 1997. The label was put together by the band, manager Simon Gallipeault, label manager Kyria Kilakos and head of promo Mariana Gianelli, following the demise of the band's former label Cargo Records. Indica is considered to be the biggest "alternative" label in Quebec. After Gallipeault's death following a skateboarding accident, GrimSkunk singer Franz Schuller took the helm as president of the company. Indica Records was started with $2000; a grassroots, do-it-yourself approach; and an overriding belief in "artist first" vision.
Armed with the mandate of supporting independent releases for great touring bands lacking label support in Canada, Indica has since grown by leaps and bounds and has expanded its repertoire to encompass a variety of genres beyond the rock/punk/alternative music on which the label was founded, including folk, pop, indie, world and electro-rock.
Indica (Greek: Ἰνδικά Indika), is the name of a book by the classical Greek physician Ctesias purporting to describe India. Written in the fifth century BC, it is the first known Greek reference to that distant land. Ctesias was the court physician to king Artaxerxes II of Persia, and the book is not based on his own experiences, but on stories brought to Persia by traders, along the Silk Road from Serica, a land north of China and India where domesticated silk originated.
The book contains the first known reference to the unicorn, ostensibly an ass in India that had a single 1.5 cubit (27 inch) horn on its head, and introduces the European world to the talking parrot, and falconry, which was not yet practiced in Europe.
Among the information apparently conveyed in the book (mostly according to second-hand accounts of its contents):
