Science fiction

Science fiction is a genre of speculative fiction dealing with imaginative concepts such as futuristic settings, futuristic science and technology, space travel, time travel, faster than light travel, parallel universes and extraterrestrial life. Science fiction often explores the potential consequences of scientific and other innovations, and has been called a "literature of ideas." It usually eschews the supernatural, and unlike the related genre of fantasy, historically science fiction stories were intended to have at least a faint grounding in science-based fact or theory at the time the story was created, but this connection has become tenuous or non-existent in much of science fiction.

Definitions

Science fiction is difficult to define, as it includes a wide range of subgenres and themes. Author and editor Damon Knight summed up the difficulty, saying "science fiction is what we point to when we say it", a definition echoed by author Mark C. Glassy, who argues that the definition of science fiction is like the definition of pornography: you do not know what it is, but you know it when you see it.

List of Big Brother 6 housemates (UK)

This is a list of the housemates of sixth series of the UK version of Big Brother, where they were observed by television viewers 24 hours a day, and each week one or more housemates were voted to be evicted by the general public until the winner, Anthony Hutton, was left.

There were sixteen housemates in total; thirteen housemates entered on day one and they were joined by three more on Day 29. They entered the Secret Garden which was decorated like a jungle, and the three secret housemates were initially only supplied with fig leaves to cover only the main essentials of their bodies. This created the idea of an Adam and Eve style jungle. With Makosi's help, they had to steal clothes and food from the main Big Brother House when the other housemates were asleep, and to make sure that the other housemates did not find out about them. At the end of their stay, Makosi had to choose two of the three secret housemates to enter the main house. She chose Orlaith and Eugene, although Kinga re-entered the house after Orlaith walked out on Day 65.

Science (TV network)

Science is an American digital cable and satellite television network that is owned by Discovery Communications. The channel features programming focusing on the fields of wilderness survival, ufology, manufacturing, construction, technology, space, prehistory and animal science.

As of February 2015, Science is available to approximately 75.5 million pay television households (64.8% of households with at least one television set) in the United States.

History

In November 1994, Discovery Networks announced plans to create four digital channels set to launch in 1996. Discovery originally named the network under the working title Quark!; this was changed before its launch to the Discovery Science Network. Discovery Science launched in October 1996 as part of the simultaneous rollout of the new channel suite (alongside Discovery Home & Leisure, Discovery Kids and Discovery Health Channel).

The channel underwent various rebrandings throughout its history. Its name was first modified to the Discovery Science Channel in 1998, and then was renamed The Science Channel in 2002, as the first network in the Discovery Networks digital suite to drop the "Discovery" brand from its name (however, international versions of the channel continue to use the "Discovery Science" name). The channel later shortened its name to just Science Channel in 2007 as part of a rebrand that included the introduction of a new logo based on the periodic table; in 2011, the network rebranded as simply Science, introducing a new logo and graphics package designed by Imaginary Forces.

Top (clothing)

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.

Design

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.

Top (comics)

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).

Fictional character biography

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.

Category of topological spaces

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.

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.
