Heart (band)

Heart is an American rock band that first found success in Canada and later in the United States and worldwide. Over the group's four-decade history it has had three primary lineups, with the constant center of the group since 1974 being sisters Ann Wilson (lead singer) and Nancy Wilson (guitarist). Heart rose to fame in the mid-1970s with music influenced by hard rock and heavy metal as well as folk music. Their popularity declined in the early 1980s, but the band enjoyed a comeback starting in 1985 and experienced even greater success with album oriented rock (AOR) hits and hard rock ballads into the 1990s. With Jupiter's Darling (2004), Red Velvet Car (2010), and Fanatic (2012), Heart made a return to its hard rock and acoustic folk roots.

To date, Heart has sold over 35 million records worldwide, including over 22.5 million in album sales in the U.S. The group was ranked number 57 on VH1's "100 Greatest Artists of Hard Rock". With Top 10 albums on the Billboard Album Chart in the 1970s, 1980s, 1990s, and 2010s, Heart is among the most commercially enduring hard rock bands in history. They were inducted into the Rock and Roll Hall of Fame in 2013.

Heart Hampshire

Heart Hampshire (formerly Ocean FM and Ocean Sound) was a British independent local radio station serving South Hampshire, West Sussex and the Isle of Wight primarily for Portsmouth, Winchester and Southampton. The station served an area of England with a high proportion of commuters to London and a higher-than-average disposable income from middle-class families and people over 45. Its target age range was 25-45.

History

Ocean Sound's predecessor, Radio Victory provided the first local commercial radio service in the South of England in 1975, with its small transmission area around Portsmouth. The station was disliked by the then regulator and when it Independent Broadcasting Authority re-advertised the Portsmouth licence to include Southampton and Winchester, Victory lost out to a new consortium called Ocean Sound Ltd. Ocean Sound proposed an expanded coverage area taking in Southampton. Radio Victory ceased operations in June 1986, three months earlier than the expiry date of its franchise, with a test transmission informing listeners of the unprecedented situation. Ocean Sound took over programme provision that October from a new purpose-built broadcast unit in a business park at Segensworth West on the western outskirts of Fareham, Hampshire.

History

Launching

Heart began broadcasting on 6 September 1994, as 100.7 Heart FM being the UK's third Independent Regional Radio station, five days after Century Radio and Jazz FM North West. The first song to be played on 100.7 Heart FM was "Something Got Me Started", by Simply Red. Its original format of "soft adult contemporary" music included artists such as Lionel Richie, Simply Red and Tina Turner. Reflecting this, its early slogan was 100.7 degrees cooler!.

Heart 106.2 began test transmissions in London in August 1995, prior to the station launch on 5 September. The test transmissions included live broadcasts of WPLJ from New York.

The Heart programming format was modified in 1996. The new format saw the "soft" AC music replaced with a generally more neutral Hot AC music playlist. Century 106 in the East Midlands became the third station of the Heart network in 2005 after GCap Media sold Century. Chrysalis' radio holdings were sold to Global Radio in 2007.

Book (graph theory)

In graph theory, a book graph (often written  ) may be any of several kinds of graph.

One kind, which may be called a quadrilateral book, consists of p quadrilaterals sharing a common edge (known as the "spine" or "base" of the book). A book of this type is the Cartesian product of a star and K₂ .

A second type, which might be called a triangular book, is the complete tripartite graph K_1,1,p. It is a graph consisting of triangles sharing a common edge. A book of this type is a split graph. This graph has also been called a .

Given a graph , one may write for the largest book (of the kind being considered) contained within .

The term "book-graph" has been employed for other uses. Barioli used it to mean a graph composed of a number of arbitrary subgraphs having two vertices in common. (Barioli did not write for his book-graph.)

2001: A Space Odyssey (novel)

2001: A Space Odyssey is a 1968 science fiction novel by Arthur C. Clarke. It was developed concurrently with Stanley Kubrick's film version and published after the release of the film. Clarke and Kubrick worked on the book together, but eventually only Clarke ended up as the official author. The story is based in part on various short stories by Clarke, most notably "The Sentinel" (written in 1948 for a BBC competition, but first published in 1951 under the title "Sentinel of Eternity"). By 1992, the novel had sold three million copies worldwide. An elaboration of Clarke and Kubrick's collaborative work on this project was The Lost Worlds of 2001.

The first part of the novel (in which aliens influence the primitive ancestors of humans) is similar to the plot of an earlier Clarke story, "Encounter in the Dawn".

Plot summary

In the background to the story in the book, an ancient and unseen alien race uses a device with the appearance of a large crystalline monolith to investigate worlds all across the galaxy and, if possible, to encourage the development of intelligent life. The book shows one such monolith appearing in ancient Africa, 3 million years B.C. (in the movie, 4 million years), where it inspires a starving group of hominids to develop tools. The ape-men use their tools to kill animals and eat meat, ending their starvation. They then use the tools to kill a leopard preying on them; the next day, the main ape character, Moon-Watcher, uses a club to kill the leader of a rival tribe. The book suggests that the monolith was instrumental in awakening intelligence.
