Gravity

Gravity or gravitation is a natural phenomenon by which all things with energy are brought toward (or gravitate toward) one another, including stars, planets, galaxies and even light and sub-atomic particles. Gravity is responsible for many of the structures in the Universe, by creating spheres of hydrogen — where hydrogen fuses under pressure to form stars — and grouping them into galaxies. On Earth, gravity gives weight to physical objects and causes the tides. Gravity has an infinite range, although its effects become increasingly weaker on farther objects.

Gravity is most accurately described by the general theory of relativity (proposed by Albert Einstein in 1915) which describes gravity not as a force but as a consequence of the curvature of spacetime caused by the uneven distribution of mass/energy; and resulting in gravitational time dilation, where time lapses more slowly in lower (stronger) gravitational potential. However, for most applications, gravity is well approximated by Newton's law of universal gravitation, which postulates that gravity is a force where two bodies of mass are directly drawn (or 'attracted') to each other according to a mathematical relationship, where the attractive force is proportional to the product of their masses and inversely proportional to the square of the distance between them. This is considered to occur over an infinite range, such that all bodies (with mass) in the universe are drawn to each other no matter how far they are apart.

Gravity (Our Lady Peace album)

Gravity is the fifth studio album by the Canadian rock band Our Lady Peace. It was released on June 18, 2002 by Columbia Records in North America. The album became a worldwide success, charting highly both in Canada and the United States with the hit singles "Somewhere Out There" and "Innocent".

The album title, Gravity, was inspired by the chorus lyrics "Falling back to me, defying gravity" from the track "Somewhere Out There". At the time of the album's release, OLP drummer Jeremy Taggart said that Gravity was "by far [their] best album".

Gravity was the first album to feature new guitarist, Steve Mazur, who replaced Mike Turner in 2002 after the latter's departure, which the band was feeling limited by Mike Turner guitar abilities in the studio. The band also wanted a guitarist who can really stand up and have a strong voice. Despite of Mike Turner departure, Turner appears on half the tracks on the album, however, having recorded parts for several songs on the album prior to his departure. This was also their last album with musician Jamie Edwards, who had performed on two prior albums and was briefly an official member, but left the band soon after the album's completion.

Gravity (American company)

Gravity is a start up Content Personalization Company based out of Los Angeles, USA. They help publishers and advertisers deliver personalized content and ads. The company was founded in 2009 by Amit Kapur, Jim Benedetto, and Steve Pearman. The company was recently acquired by AOL in January 2014 for a reported $90.7 million.

Products

Gravity offers Content Personalization by using something they developed using the "interest graph" to tailor specific interests of each user on social websites. The "interest graph" uses real time ingestion to process content and behavior data. The data then gets a Semantic and a Virility analysis and the "interest graph" is created according to each specific user. Gravity also uses these graphs in relation to specific brands. The data presented in these graphs give specific information on what customers a company has and their preferences. The companies using Gravity "interest graphs" are able to directly see what their customers want and expect. The graphs enable brands to eliminate focus groups, market research, surveys, etc.

Quasigroup

In mathematics, especially in abstract algebra, a quasigroup is an algebraic structure resembling a group in the sense that "division" is always possible. Quasigroups differ from groups mainly in that they need not be associative.

A quasigroup with an identity element is called a loop.

Definitions

There are at least two equivalent formal definitions of quasigroup. One defines a quasigroup as a set with one binary operation, and the other, from universal algebra, defines a quasigroup as having three primitive operations. We begin with the first definition.

A quasigroup (Q, ∗) is a set, Q, with a binary operation, ∗, (that is, a magma), obeying the Latin square property. This states that, for each a and b in Q, there exist unique elements x and y in Q such that both

hold. (In other words: Each element of the set occurs exactly once in each row and exactly once in each column of the quasigroup's multiplication table, or Cayley table. This property ensures that the Cayley table of a finite quasigroup is a Latin square.)

Loop (band)

Loop are an English alternative rock band, formed in 1986 in Croydon, Surrey.

The band went through several lineup changes, with frontman Robert Hampson being the only permanent band member. They split in 1991, with the 1989–90 lineup of Hampson, John Wills, Scott Dawson and Neil Mackay reforming in 2013 for a series of gigs. In November 2014, Hampson unveiled a new lineup of the band with himself as the sole original band member.

Career

Loop were formed in 1986 by Robert Hampson (vocals, guitar), with his then-girlfriend Becky Stewart on drums. Bex was later replaced by John Wills (The Servants) and Glen Ray, with James Endeacott on guitar. Initially releasing records on Jeff Barrett's Head label, their first release was 1987's '16 Dreams', with debut album Heaven's End following later that year. The band was then signed up by Chapter 22 Records.

Loop returned with a more polished sound with the 'Collision' single in 1988. A second album Fade Out followed in 1989, reaching No. 51 on the UK album chart. Endeacott left the band in 1988, Scott Dowson joined the following year. They changed labels again to Beggars Banquet subsidiary Situation Two, releasing the 'Arc-Lite' single in 1989 and the third and final studio album A Gilded Eternity in 1990.
