Work (electrical)

Electrical work is the work done on a charged particle by an electric field. The equation for 'electrical' work is equivalent to that of 'mechanical' work:

where

The electrical work per unit of charge, when moving a negligible test charge between two points, is defined as the voltage between those points.

Overview

Qualitative overview

Particles that are free to move, if positively charged, normally tend towards regions of lower voltage (net negative charge), while if negatively charged they tend to shift towards regions of higher voltage (net positive charge).

However, any movement of a positive charge into a region of higher voltage requires external work to be done against the field of the electric force, work equal to that electric field would do in moving that positive charge the same distance in the opposite direction. Similarly, it requires positive external work to transfer a negatively charged particle from a region of higher voltage to a region of lower voltage.

The electric force is a conservative force: work done by a static electric field is independent of the path taken by the charge. There is no change in the voltage (electric potential) around any closed path; when returning to the starting point in a closed path, the net of the external work done is zero. The same holds for electric fields.

Work of art

A work of art, artwork, art piece, piece of art or art object is an aesthetic physical item or artistic creation. Apart from "work of art", which may be used of any work regarded as art in its widest sense, including works from literature and music, these terms apply principally to tangible, portable forms of visual art:

Used more broadly, the term is less commonly applied to:

Work (Rihanna song)

"Work" is a song recorded by Barbadian singer Rihanna for her eighth studio album, Anti (2016). The song features a verse by Canadian rapper Drake. The artists co-wrote the single with PartyNextDoor, Allen Ritter, Rupert Thomas, R. Stephenson, Monte Moir, and Boi-1da; the latter is also the producer.

Upon its release, "Work" received mixed reviews from music critics. The song debuted at number nine and has so far peaked at number seven on the Billboard Hot 100, becoming Rihanna's 27th and Drake's 15th top ten entry on the chart. It has also peaked within the top ten of the charts in Australia, Canada, France, Hungary, Spain, and the United Kingdom.

Writing and development

"Work" was written by the artists, PartyNextDoor, Allen Ritter, Rupert "Sevn" Thomas, Monte Moir, R. Stephenson, and Boi-1da; the latter is also the producer. In the summer of 2015, Thomas, Ritter, Boi-1da and Martin Mason among others, stayed at Drake house in Los Angeles for a mid-week period. Thomas described the time spent at the home as a "beat factory, everyone was sitting there working and collaborating with each other." Thomas created a beat which was dancehall-influenced; he later played it for Boi-1da to which he positively responded, "We’re both Jamaican-Canadian. It was just something in our DNA, so it woke him up, and we started remembering all these old dancehall songs from the '90s." Boi-1da came with up idea for sampling an "old school dancehall rhythm" and after that the chords were made with Ritter and past it, "everything went organically".

Los (Blake)

In the mythological writings of William Blake, Los is the fallen (earthly or human) form of Urthona, one of the four Zoas. He is referred to as the "eternal prophet" and creates the visionary city of Golgonooza. Los is regularly described as a smith, beating with his hammer on a forge, which is metaphorically connected to the beating of the human heart. The bellows of his forge are the human lungs. Los's emanation, Enitharmon, represents spiritual beauty and embodies pity, but at the same time creates the spatial aspect of the fallen world, weaving bodies for men and creating sexual strife through her insistence upon chastity. In the Book of Urizen (1794), Los and Enitharmon have the child, Orc, who is the embodiment of the spirit of revolution. It is of interest to note that the name 'Los' is, by common critical acceptance, an anagram of 'Sol', the Latin word for 'sun'. Such innovations are common in many of Blake's prophetic poems.

Background

Blake attributed the origin of Los and many of his prophetic works to his home in Lambeth: "Los descended to me... trembling I stood... in the Vale of Lambeth; but he kissed me and wished me health".

Reise, Reise

Reise, Reise (German pronunciation: [ʁaɪzə, ʁaɪzə], a German wake-up call, literally "(a)rise, (a)rise", although it can also be interpreted as meaning "journey, journey", or as a command "travel, travel") is Neue Deutsche Härte band Rammstein's fourth studio album. It was released on September 27, 2004 in Germany and followed shortly by its release across Europe. It was released in North America on November 16, 2004. The album was recorded in a span of two years at El Cortijo Studios in Málaga, Spain. It was produced by the band themselves along with Swedish record producer Jacob Hellner. The album charted in the top ten in several European charts and was a number one hit in Germany, Austria, Switzerland, Iceland, Finland, Estonia and Mexico. As of February 2006, the album has shipped 1.5 million copies globally.

Recording

The album was recorded in Spain (El Cortijo Studio, Malaga) and produced by Jacob Hellner and Rammstein. The band recorded several songs during the sessions for "Reise, Reise" which were omitted from the album's final track listing and were later released on their follow-up album Rosenrot. A statement from the band's management regarding the upcoming collection reads as follows:
