Hex or HEX may refer to:
A hex is an item of rock climbing equipment used to protect climbers from injury during a fall. They are intended to be wedged into a crack or other opening in the rock, and do not require a hammer to place. They were developed as an alternative to pitons, which are hammered into cracks and are more prone to damage the rock. Most commonly, a carabiner will be used to join the hex to the climbing rope by means of a loop of webbing, cord or a cable which is part of the hex.
Hexes are a type of nut, a hollow eccentric hexagonal prism with tapered ends, usually threaded with webbing, a swaged cable, or a cord. They are manufactured by several firms, with a range of sizes varying from about 10–100 millimetres (0.4–4 in) wide. Climbers select a range of sizes to use on a specific climb based on the characteristics of the cracks in the rock encountered on that particular climb. Sides may be straight or curved although the functioning principles remain the same no matter which shape is selected; the lack of sharp corners on curved models may make them easier to remove from the rock.
Hex is a fictional computer featuring in the Discworld novels by Terry Pratchett. First appearing in Soul Music, Hex is an elaborate, magic-powered and self-building computer (not unlike the 'shamble', a kind of magical device used by the Wizards of the Discworld) and is housed in the basement of the High Energy Magic Building at the Unseen University (UU) in the twin city of Ankh-Morpork.
Hex is a computer unlike any other the Disc has ever seen, which is not particularly exceptional since previously all other "computers" on the Disc had consisted of druidic stone circles. Programmed via 'Softlore', Hex runs and evolves under the watchful eyes of wizard Ponder Stibbons, who becomes the de facto IT manager at UU because he's the only one who understands what he's talking about.
Hex has its origins in a device that briefly appeared in Soul Music, created by Ponder Stibbons and some student Wizards in the High Energy Magic building. In this form it was simply a complex network of glass tubes, containing ants. The wizards could then use punched cards to control which tubes the ants could crawl through, enabling it to perform simple mathematical functions.
Heaven, the heavens or seven heavens, is a common religious, cosmological, or transcendent place where heavenly beings such as gods, angels, jinn, saints, or venerated ancestors are said to originate, be enthroned, or to live. According to the beliefs of some religions, heavenly beings can descend to earth or incarnate, and earthly beings can ascend to Heaven in the afterlife, or in exceptional cases enter Heaven alive.
Heaven is often described as a "higher place", the holiest place, a Paradise, in contrast to Hell or the Underworld or the "low places", and universally or conditionally accessible by earthly beings according to various standards of divinity, goodness, piety, faith, or other virtues or right beliefs or simply the will of God. Some believe in the possibility of a Heaven on Earth in a World to Come.
Another belief is in an axis mundi or world tree which connects the heavens, the terrestrial world, and the underworld. In Indian religions, Heaven is considered as Svarga loka, and the soul is again subjected to rebirth in different living forms according to its karma. This cycle can be broken after a soul achieves Moksha or Nirvana. Any place of existence, either of humans, souls or deities, outside the tangible world (Heaven, Hell, or other) is referred to as otherworld.
"Heaven" is a song recorded by American rapper Jay-Z from his twelfth studio album Magna Carta Holy Grail (2013) featuring American recording artist Justin Timberlake. The song was written by Jay-Z, The-Dream, members of R.E.M., Adrian Younge, Timbaland, and Jerome "J-Roc" Harmon while the production was handled by the latter two. During the song, Jay-Z touches on subjects of religious allegory and an interrogation of organized religion. The song has since peaked at number 10 on the Billboard Bubbling Under Hot 100 Singles.
On "Heaven", Jay-Z questions the meaning of religion and once again shoots down rumors that he is part of the secret organization Illuminati. He explained the song in a promotional video for Samsung saying,
The song indulges in religious allegory, and is one of the few songs on Magna Carta Holy Grail that touch upon existential and spiritual themes. Throughout the song he ponders faith, superstition and free thinking.
The songs features Jay-Z rapping a lyric of rock band, R.E.M.'s 1991 single "Losing My Religion". Following the album's release, former frontman of R.E.M. Michael Stipe told NME that he's "thrilled" and it was a "great honor", that Jay-Z included the lyrics in one of his songs.
"Heaven" is the title of a popular song from 2004 by the American Tejano/Chicano rock band Los Lonely Boys. The song was written by brothers Henry, Jojo and Ringo Garza, who comprise the foundation of the band, and it appears on their multi-platinum self-titled album.
Released as a single in mid-2004, "Heaven" reached the Top 40 on the U.S. Billboard Hot 100 chart, peaking at 16 in August. Later that year, the song began a sixteen week run at number 1 on the Billboard Adult Contemporary chart in October. It was also a minor hit at country radio, where it peaked at number 46.
AllMusic reviewer Thom Jurek describes the song as "infectious" and draws comparisons to the music of Freddie King, Stevie Ray Vaughan and Los Lobos. He states that "Heaven" is "a single in the old sense of the word: killer hook, easy groove, a slippery but unmistakable bridge with a beautiful vocal to boot -- all coming in under four minutes."
The success of "Heaven" led to two Grammy Award nominations and one win for the band at the 47th Grammy Awards, held in early 2005. The song won in the category Best Pop Performance by a Duo group, while Los Lonely Boys were nominated in the category Best New Artist, losing out to Maroon 5.
