Joker (playing card)

The Joker is a playing card found in most modern card decks, as an addition to the standard four suits (clubs, diamonds, hearts and spades). Originating in the United States during its civil war, the card is unique in that it lacks an industry-wide standard appearance. Created as a trump card for Euchre, it has since been adopted into many other card games where it may function as a wild card.

Origin

In the game of Euchre, the highest trump card is the Jack of the trump suit, called the right bower (from the German Bauer); the second-highest trump, the left bower, is the Jack of the suit of the same color as trumps. Around 1860, American Euchre players may have devised a higher trump, the "Best Bower", out of a blank card.

Samuel Hart is credited with printing the first illustrated "Best Bower" card in 1863 with his "Imperial Bower". Best Bower-type jokers continued to be produced well into the 20th-century. Cards labelled "Joker" began appearing around the late 1860s with some depicting clowns and jesters. It is believed that the term "Joker" comes from Juker or Juckerspiel, the original German spelling of Euchre. One British manufacturer, Charles Goodall, was manufacturing packs with Jokers for the American market in 1871. The first joker for the domestic British market was sold in 1874.

Martha Wayne

Martha Wayne (née Martha Kane) is a fictional character of the Batman series of comic books, published by DC Comics. She is Bruce Wayne's mother and Dr. Thomas Wayne's wife. When she and her husband are murdered during a holdup, her son swears to avenge their deaths by fighting crime and fulfills this as Batman.

Background

Martha Wayne first appeared in Detective Comics #33 (November 1939) in a story by Bob Kane and Bill Finger which detailed the origin of Batman. Initially little more than a cipher whose death inspired her heroic son, later comics would expand upon her history.

Born Martha Kane (a maiden name given in homage to co-creator Bob Kane), Martha was the heir to the Kane Chemical fortune and a member of one of Gotham City's wealthiest families. It has not been revealed whether she has any connection to the other prominent Kanes of Gotham, Kathy Kane (Batwoman) or Bette Kane (Flamebird). Despite her Irish-Catholic background, in her youth, Martha had a reputation as a notorious party girl, socialite, and debutante, frequenting all the most prestigious country clubs, night clubs, and soirees. She also had a developed social conscience and often used her family's wealth and status to champion causes and charities.

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".
