A top is a toy designed to be spun rapidly on the ground, the motion of which causes it to remain precisely balanced on its tip because of inertia. Such toys have existed since antiquity. Traditionally tops were constructed of wood, sometimes with an iron tip, and would be set in motion by aid of a string or rope coiled around its axis which, when pulled quickly, caused a rapid unwinding that would set the top in motion. Today they are often built of plastic, and modern materials and manufacturing processes allow tops to be constructed with such precise balance that they can be set in motion by a simple twist of the fingers and twirl of the wrist without need for string or rope.
The motion of a top is produced in the most simple forms by twirling the stem using the fingers. More sophisticated tops are spun by holding the axis firmly while pulling a string or twisting a stick or pushing an auger. In the kinds with an auger, an internal weight rotates, producing an overall circular motion. Some tops can be thrown, while firmly grasping a string that had been tightly wound around the stem, and the centrifugal force generated by the unwinding motion of the string will set them spinning upon touching ground.
A top is clothing that covers at least the chest, but which usually covers most of the upper human body between the neck and the waistline. The bottom of tops can be as short as mid-torso, or as long as mid-thigh. Men's tops are generally paired with pants, and women's with pants or skirts. Common types of tops are t-shirts, blouses and shirts.
The neckline is the highest line of the top, and may be as high as a head-covering hood, or as low as the waistline or bottom hem of the top. A top may be worn loose or tight around the bust or waist, and may have sleeves or shoulder straps, spaghetti straps (noodle straps), or may be strapless. The back may be covered or bare. Tops may have straps around the waist or neck, or over the shoulders.
N.B. Some authors use the name Top for the category with topological manifolds as objects and continuous maps as morphisms.
As a concrete category
Like many categories, the category Top is a concrete category (also known as a construct), meaning its objects are sets with additional structure (i.e. topologies) and its morphisms are functions preserving this structure. There is a natural forgetful functor
to the category of sets which assigns to each topological space the underlying set and to each continuous map the underlying function.
Come Sail Away – The Styx Anthology is a musical album by Styx, released on May 4, 2004. It is a compilation consisting of two compact discs and contains a thorough history of the band. The album encompasses many of the band's most popular and significant songs, ranging from the band's first single from their self-titled album, "Best Thing," through the song "One with Everything," a track included on Styx's most recent album at the time of release, Cyclorama.
This is the only Styx compilation album to date to combine the original versions of songs from the band's early Wooden Nickel albums with their later material. Their Wooden Nickel breakout hit "Lady" was included on the 1995 Greatest Hits collection, but as a note-for-note re-recording, labelled "Lady '95." As such, this is the first truly career-spanning collection for the band ever compiled.
Anthology is a compilation of Motown hits by pop and R&B singer Michael Jackson with additional hits by The Jackson 5 and rare, unreleased material from 1973. The album was originally released in the U.S. on November 14, 1986 and re-released on November 8, 1995 and has sold three million copies worldwide.
In 2008, in celebration of Jackson's 50th birthday, Anthology was re-released under Universal Music's Gold series.
Tracks with an asterisk represent their original undubbed renditions.
The project was first announced by Deadline on April 12, 2011, a treasure hunt film titled Gold in the vein of The Treasure of the Sierra Madre, written by Patrick Massett and John Zinman as a writing sample and developed by Paul Haggis, who showed it to Michael Mann. Mann liked the script and joined as director and producer for his banner Forward Pass, which Haggis would also produce along with Michael Nozik. Later in August 2011, Variety reported that Christian Bale was being eyed for the lead role, and it was one of the several projects he had to make choice for.
