Origin (mathematics)

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.

Cartesian coordinates

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.

Other coordinate systems

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 (Evanescence album)

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.

Background

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.

Dreams (2004 film)

Dreams is a 2004 Tamil Malayalam romantic film directed by Kasthuri Raja and produced by Saraswathi Srikanth. The film featured Raja's son Dhanush in the lead role with Diya and Parul Yadav playing other pivotal roles. The film opened to negative reviews and became a failure at the box office.

Cast

Production

The project was launched shortly after the success of Thulluvadho Ilamai in 2002, but as Dhanush's Kaadhal Kondein became a large success, Dreams was stalled temporarily as Dhanush's dates became blocked. The film ran into a legal tussle with the makers of his other film, Sullan, with the producers adamant that Dreams was released first although to no avail. The film's delay meant that Dhanush shot ten straight days for the project to complete it, while the delay also had resulted in failings in continuity. By the time of the release, the producer Srikanth and director Kastoori Raja were still engaged in a legal tussle.

Dreams (Fleetwood Mac song)

"Dreams" is a song written by singer Stevie Nicks, for the group Fleetwood Mac's 1977 album, Rumours. It is the only U.S. No. 1 hit for the group where it sold over a million copies, and remains one of their best known songs.

Background and writing

The members of Fleetwood Mac were experiencing emotional upheavals while recording Rumours. Drummer Mick Fleetwood was going through a divorce. Bassist John McVie was separating from his wife, keyboardist Christine McVie. Guitarist Lindsey Buckingham and lead singer Stevie Nicks were ending their eight-year relationship. "We had to go through this elaborate exercise of denial," explained Buckingham to Blender magazine, "keeping our personal feelings in one corner of the room while trying to be professional in the other."

Nicks wrote the song at the Record Plant studio in Sausalito, California, in early 1976. "One day when I wasn't required in the main studio," remembers singer Stevie Nicks to Blender, "I took a Fender Rhodes piano and went into another studio that was said to belong to Sly, of Sly & the Family Stone. It was a black-and-red room, with a sunken pit in the middle where there was a piano, and a big black-velvet bed with Victorian drapes."

Dreams (Klaus Schulze album)

Dreams is the nineteenth album by Klaus Schulze. It was released in 1986, and in 2005 was the third Schulze album reissued by Revisited Records. The reissue bonus track was released early 2004 in Hambühren as a limited promo CD Ion.
