In mathematics, the origin of a Euclidean space is a special point, usually denoted by the letter O, used as a fixed point of reference for the geometry of the surrounding space.
In a Cartesian coordinate system, the origin is the point where the axes of the system intersect. The origin divides each of these axes into two halves, a positive and a negative semiaxis. Points can then be located with reference to the origin by giving their numerical coordinates—that is, the positions of their projections along each axis, either in the positive or negative direction. The coordinates of the origin are always all zero, for example (0,0) in two dimensions and (0,0,0) in three.
In a polar coordinate system, the origin may also be called the pole. It does not itself have well-defined polar coordinates, because the polar coordinates of a point include the angle made by the positive x-axis and the ray from the origin to the point, and this ray is not well-defined for the origin itself.
Origin is an online gaming, digital distribution and digital rights management (DRM) platform developed by Electronic Arts that allows users to purchase games on the internet for PC and mobile platforms, and download them with the Origin client (formerly EA Download Manager, EA Downloader and EA Link). Origin for Mac has been available since February 8, 2013.
Origin features social features like profile management, networking with friends with chat and direct game joining along with an in-game overlay, streaming via TwitchTV and sharing of game library and community integration with networking sites like Facebook, Xbox Live, PlayStation Network, and Nintendo Network. Electronic Arts has stated that it wanted Origin to match Valve's Steam service, Origin's leading competitor, by the end of March 2012, by adding cloud game saves, auto-patching, achievements and rewards, and cross-platform releases. Origin has over 50 million registered users.
Origin is the first demo album by the alternative metal band Evanescence. It was released in 2000 on Bigwig Enterprises. Only 2,500 album copies were pressed and sold at the band's live concerts in Little Rock, Arkansas, and on the Bigwig Enterprises website.
Due to the limited numbers pressed and the band's success, copies of the album were being sold for US$400 on eBay following Fallen's release, and it became nearly impossible to find an original copy. Although it is commonly referred to as a full-length album, lead vocalist and co-founder Amy Lee refers to it as a "dressed up" demo CD, and urges fans to simply download the album, rather than purchase it. It contains earlier versions of "Whisper", "Imaginary", and "My Immortal", which appeared on the band's debut studio album, Fallen, as well as a re-recorded version of the track "Where Will You Go", which previously appeared on the Evanescence EP released in 1998. Three tracks were omitted: "Catherine", "Spanish", and "Listen to the Rain". "Listen to the Rain" was planned to be sandwiched between the tracks "Eternal" and "Demise", but after it was cut, "Eternal" and "Demise" were merged into one track.
Hydra may refer to:
Hydra (also known as Hydra: The Lost Island) is a 2009 low-budget monster movie by Andrew Prendergast and Peter Sullivan, which blends elements of horror, thriller and classical mythology. It was made for cable TV and subsequently internationally distributed on DVD.
Young archaeologist Dr. Valerie Cammon (Polly Shannon) and her colleague Dr. Kim (Philip Moon) go by ship to a volcanic island in the Mediterranean sea. While she seeks relics in a cave, a seaquake sinks their ship without survivors. At about the same time all archaeologists except for Dr. Cammon get eaten by the re-awakened ancient Lernaean Hydra.
During the tempest, a whole island disappears. Two months later, Vincent (Alex McArthur) and Dixie Camden (Jana Williams) intended to organize a man-hunt for cranky millionaires. Their Captain (Michael Shamus Wiles), unaware of the Hydra, suggests the nearby, aforementioned island as a substitute.
Four ex-convicts, Tim Nolan George Stults), Gwen Russell (Dawn Olivieri), Bob Crick (James Wlcek) and Ronnie Kaplan (Texas Battle), are marooned at the shore and given 24 hours' headstart.
Hydra was a chess machine, designed by a team with Dr. Christian "Chrilly" Donninger, Dr. Ulf Lorenz, GM Christopher Lutz and Muhammad Nasir Ali. Since 2006 the development team consisted only of Donninger and Lutz. Hydra was under the patronage of the PAL Group and Sheikh Tahnoon Bin Zayed Al Nahyan of Abu Dhabi. The goal of the Hydra Project was to dominate the computer chess world, and finally have an accepted victory over humans.
Hydra represented a potentially significant leap in the strength of computer chess. Design team member Lorenz estimates its FIDE equivalent playing strength to be over Elo 3000, and this is in line with its results against Michael Adams and Shredder 8, the former micro-computer chess champion.
Hydra began competing in 2002 and played its last game in June 2006. In June 2009, Christopher Lutz stated that "unfortunately the Hydra project is discontinued." The sponsors decided to end the project.
The Hydra team originally planned to have Hydra appear in four versions: Orthus, Chimera, Scylla and then the final Hydra version – the strongest of them all. The original version of Hydra evolved from an earlier design called Brutus and works in a similar fashion to Deep Blue, utilising large numbers of purpose-designed chips (in this case implemented as a field-programmable gate array or FPGA). In Hydra, there are multiple computers, each with its own FPGA acting as a chess coprocessor. These co-processors enabled Hydra to search enormous numbers of positions per second, making each processor more than ten times faster than an unaided computer.
