Propagator
In quantum mechanics and quantum field theory, the propagator is a function that specifies the probability amplitude for a particle to travel from one place to another in a given period of time, or to travel with a certain energy and momentum. In Feynman diagrams, which serve to calculate the rate of collisions in quantum field theory, virtual particles contribute their propagator to the rate of the scattering event described by the respective diagram. Propagators may also be viewed as the inverse of the wave operator appropriate to the particle, and are, therefore, often called (causal) Green's functions (called "causal" to distinguish it from the elliptic Laplacian Green's function).

D'Alembert operator
In special relativity, electromagnetism and wave theory, the d'Alembert operator (denoted by a box: ), also called the d'Alembertian, wave operator, box operator or sometimes quabla operator (cf. nabla symbol) is the Laplace operator of Minkowski space. The operator is named after French mathematician and physicist Jean le Rond d'Alembert.

In Minkowski space, in standard coordinates (t, x, y, z), it has the form

Here   is the 3-dimensional Laplacian and ημν  is the inverse Minkowski metric with

, ,  for .

Note that the μ and ν summation indices range from 0 to 3: see Einstein notation.

(Some authors  alternatively use the negative metric signature of (− + + +), with .)

Lorentz transformations leave the Minkowski metric invariant, so the d'Alembertian yields a Lorentz scalar. The above coordinate expressions remain valid for the standard coordinates in every inertial frame.
Socialist Labour Party (UK, 1903)
The Socialist Labour Party was a socialist political party in the United Kingdom.  It was established in 1903 as a splinter from the Social Democratic Federation (SDF) by James Connolly, Neil Maclean and SDF members impressed with the politics of the American socialist Daniel De Leon, a Marxist theoretician and leading figure of the Socialist Labor Party of America. After decades of existence as a tiny organisation, the group was finally disbanded in 1980.

Daniel De Leon
Daniel De Leon (/dəˈliːɒn/; December 14, 1852 – May 11, 1914), alternatively spelled Daniel de León, was a Curaçao-born American socialist newspaper editor, politician, Marxist theoretician, and trade union organizer. He is regarded as the forefather of the idea of revolutionary industrial unionism and was the leading figure in the Socialist Labor Party of America from 1890 until the time of his death. De Leon was a co-founder of the Industrial Workers of the World and much of his ideas and philosophy contributed to the creations of Socialist Labor parties across the english-speaking world, including: Australia, the United Kingdom, Canada, and the Socialist Trade and Labor Alliance.

Southern New England Soccer League
The Southern New England Soccer League was a semi-professional soccer league based in New England which was established in 1914 and collapsed in 1921.  During its short existence, it featured some of the top teams in the northeast United States.  Dissatisfaction with league mismanagement led to the end of the SNESL in 1921 as several teams moved to the newly created American Soccer League.

American Soccer League (1921–1933)
The American Soccer League, established on May 7, 1921 by a group of investors, was the first of four different professional soccer sports leagues in the United States to use the ASL name. It was formed by the merger of teams from the National Association Football League and the Southern New England Soccer League. For several years the ASL's popularity rivaled the popularity of the National Football League. Disputes with the United States Football Association and FIFA, as well as the onset of the Great Depression, led to the league's collapse in spring 1933.

Tipoolithus
Tipoolithus is an oogenus of fossil egg native to the Irbzer Formation in Morocco. Its classification is uncertain, but it most closely resembles Laevisoolithids, and like members of that oofamily, it was laid by an enantiornithine bird or small theropod.

Egg fossil
Egg fossils or oofossils are the fossilized remains of eggs laid by ancient animals. As evidence of the physiological processes of an animal, egg fossils are considered a type of trace fossil. Under rare circumstances a fossil egg may preserve the remains of the once-developing embryo inside, in which case it also contains body fossils. A wide variety of different animal groups laid eggs that are now preserved in the fossil record beginning in the Paleozoic. Examples include invertebrates like ammonoids as well as vertebrates like fishes, possible amphibians, and reptiles. The latter group includes the many dinosaur eggs that have been recovered from Mesozoic strata. Since the organism responsible for laying any given egg fossil is frequently unknown, scientists classify eggs using a parallel system of taxonomy separate from but modeled after the Linnaean system. This "parataxonomy" is called veterovata.

Władysław Orlicz
Władysław Roman Orlicz (May 24, 1903 – August 9, 1990) was a Polish mathematician of Lwów School of Mathematics. His main interests were functional analysis and topology: Orlicz spaces are named after him.

Orlicz space
In mathematics, and especially in harmonic analysis and functional analysis, an Orlicz space is a type of function space which generalizes Lp spaces. Like  spaces, they are Banach spaces. The spaces are named for Władysław Orlicz, who was the first to define them in 1932.

Besides  spaces, a variety of function spaces arising naturally in analysis are Orlicz spaces. One such space is , which arises in the study of Hardy–Littlewood maximal functions, consisting of measurable functions  such that

Here  is the positive part of the logarithm. Also included in the class of Orlicz spaces are many of the most important Sobolev spaces. In addition, the Orlicz sequence spaces are examples of Orlicz spaces.

Louis Marchand
Louis Marchand (2 February 1669 – 17 February 1732) was a French organist, harpsichordist and composer. Born into an organist's family, Marchand was a child prodigy and quickly established himself as one of the best known French virtuosos of his time. He worked as organist of numerous churches and, for a few years, as one of the four organistes du roy. Marchand had a violent temperament and an arrogant personality, and his life was filled with scandals, publicized and widely discussed both during his lifetime and after his death. Despite his fame, few of his works survive to this day, and those that do almost all date from his early years. Nevertheless, a few pieces of his, such as the organ pieces Grand dialogue and Fond d'orgue have been lauded as classic works of the French organ school.

French organ school
The French organ school formed in the first half of the 17th century. It progressed from the strict polyphonic music of Jean Titelouze (c. 1563–1633) to a unique, richly ornamented style with its own characteristic forms that made full use of the French classical organ. Instrumental in establishing this style were Louis Couperin (c. 1626–1661), who experimented with structure, registration and melodic lines, expanding the traditional polyphonic forms, and Guillaume-Gabriel Nivers (1632–1714), who established the distinct forms and styles of what was to become the French organ tradition.

Please Describe Yourself
Please Describe Yourself is the debut studio album by the British alternative rock band Dogs Die in Hot Cars. It was first released on 12 July 2004 in the United Kingdom on V2 Records. After releasing several limited-edition singles and the extended play Man Bites Man, the band released the album to critical praise.

The album reached number 44 on the UK Albums Chart, and was preceded by the singles "Godhopping" and "I Love You 'Cause I Have To" and "Lounger".

Man Bites Man
The Man Bites Man EP was a CD containing 4 tracks that was used to promote Dogs Die in Hot Cars, who were at the time working on their debut album: Please Describe Yourself. The release was limited to 1,000 copies. The third track on this CD was used in an advertising campaign for Boots. Also, the recording of "Pastimes & Lifestyles" found on this EP is different from that of the version found on their debut - the most notable difference being that the bridge before the last chorus on this version is longer.

Clive Langer and Alan Winstanley (who produced the band's debut album) produced the first track on this CD, while Paul Tipler produced tracks 2 and 4, and track 3 was produced by Craig Macintosh - the band's lead singer. Macintosh uploaded many of the band's tracks to SoundCloud.
