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.
The Top is a fictional character, a supervillain in the DC Universe. One of the earliest members of the Silver Age Flash's "Rogues' Gallery", the character debuted in The Flash #122 (August 1961).
Roscoe Dillon is a small-time crook who turns his childhood obsession with tops into a criminal persona. Roscoe taught himself how to spin around fast enough to deflect bullets and produce other semi-useful effects. The Top soon discovers that the spinning somehow increased his intelligence as well, allowing him to create a variety of trick tops. He tried to blackmail the world with an Atomic Top that would destroy half the world when it slowed down and imprisoned the Flash inside it, but the Flash vibrated out of it and sent it into space. His unique gimmick and moderate success in crime soon makes him a respected member of the Flash's rogues gallery. He dates Golden Glider, Captain Cold's sister, while coaching her on ice skating. Eventually, the Top develops immense psionic powers, as years of spinning moves dormant brain cells to the outer areas of his brain, endowing him with mental powers.
In mathematics, the category of topological spaces, often denoted Top, is the category whose objects are topological spaces and whose morphisms are continuous maps or some other variant; for example, objects are often assumed to be compactly generated. This is a category because the composition of two continuous maps is again continuous. The study of Top and of properties of topological spaces using the techniques of category theory is known as categorical topology.
N.B. Some authors use the name Top for the category with topological manifolds as objects and continuous maps as morphisms.
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.
In music, order is the specific arrangement of a set of discrete entities, or parameters, such as pitch, dynamics, or timbre.
Order is particularly important in the theories of compositional techniques originating in the 20th century such as the twelve-tone technique and serialism. Analytical techniques such as set theory take care to distinguish between ordered and unordered collections. In traditional theory concepts such voicing and form include ordering. For example, many musical forms, such as rondo, are defined by the order of their sections.
In the fictional Guardians of Time Trilogy, author Marianne Curley constructs a highly detailed alternate universe in which much of the action of the series takes place, unknown to the regular world. In this universe, two organizations battle for control over time.
The Guardians of Time (known also as The Guard) is a society dedicated to preserving history against the attempts of the Order of Chaos to alter it. It is headed by a sexless immortal called Lorian, who is backed by a Tribunal of nine members, each a representative of a house.
The headquarters of the Tribunal, as well as the Guard itself, is located in Athens, year 200 BC, outside of the mortal measurements of time. For their purposes, they also use a place called the Citadel, connected to another area known as the labyrinth (also used by Order of Chaos) which serves as a disembarkation point for the Guards' missions into the past. Guard meetings frequently take place in Arkarian's, a Guard member's, abode hidden within the depths of a mountain. Connected to this mountain is the hidden city of Veridian and later learned, also connected to Neriah's fortress.
