Holiday (America album)

Holiday is the fourth original studio album by American folk rock band America, released by Warner Bros. Records in June 1974 (see 1974 in music). The album was produced in London by noted Beatles producer George Martin.

The album was a big hit in the US, reaching number 3 on the Billboard album chart and being certified gold by the RIAA. It produced two hit singles: "Tin Man" reached number 4 on the Billboard singles chart and went to number 1 on both the adult contemporary chart as well as the Radio & Records chart; and "Lonely People" which peaked at number 5 on the Billboard singles chart and also hit number 1 on the adult contemporary chart. Several other songs received radio airplay on FM stations playing album tracks, including "Baby It's Up To You" and "Another Try".

History

Bandmember Dewey Bunnell was thrilled at the prospect of working with Martin as producer. He was quoted as saying that it "was great working with George. It was like we knew each other. We were familiar with the Beatles, of course, and we had that British sense of humor." In a separate interview, Dan Peek recalled to Circus magazine: "Gerry (Beckley) had been in England, and we'd talked about using George Martin as our producer. He's such a hot arranger, thinking about all the stuff he's done. There were several other people we wanted to use, but that idea sort of flashed and George was available."

Christmas music

Christmas music comprises a variety of genres of music normally performed or heard around the Christmas season.

History

Early music

Music was an early feature of the Christmas season and its celebrations. The earliest examples are hymnographic works (chants and litanies) intended for liturgical use in observance of both the Feast of the Nativity and Theophany, many of which are still in use by the Eastern Orthodox Church. The 13th century saw the rise of the carol written in the vernacular, under the influence of Francis of Assisi.

In the Middle Ages, the English combined circle dances with singing and called them carols. Later, the word carol came to mean a song in which a religious topic is treated in a style that is familiar or festive. From Italy, it passed to France and Germany, and later to England. Christmas carols in English first appear in a 1426 work of John Audelay, a Shropshire priest and poet, who lists 25 "caroles of Cristemas", probably sung by groups of wassailers, who went from house to house. Music in itself soon became one of the greatest tributes to Christmas, and Christmas music includes some of the noblest compositions of the great musicians.

Degrassi: The Next Generation (season 3)

The third season of Degrassi: The Next Generation commenced airing in Canada on 17 September 2003, concluded on 5 April 2004 and contains twenty-two episodes. Degrassi: The Next Generation is a Canadian serial teen drama television series. This season depicts the lives of a group of high school freshman and sophomores as they deal with some of the challenges and issues teenagers face such as dysfunctional families, sex, homosexuality, homophobia, theft, self-harm, domestic violence, abortion, emancipation and relationships.

Every episode is named after a song from the 1980s. Filming began on 26 May 2003, and ended in November 2003.

The third season aired Wednesdays at 8:30 p.m. on CTV, a Canadian terrestrial television network, and premiered with a sixty-minute special, "Father Figure", which form the first two episodes of the season. When the season returned to the schedules in January 2004 following a break over the Christmas period, it aired on Mondays at 8:30 p.m. In the United States, it was broadcast on The N, a digital cable network aimed at teenagers and young adults. The season was released on DVD as a three disc boxed set on 28 March 2006 by Alliance Atlantis Home Entertainment in Canada, and by FUNimation Entertainment in the US. Registered users of the Canadian and US iTunes Stores are also able purchase and download the season for playback on home computers and certain iPods.

Order and disorder (physics)

In physics, the terms order and disorder designate the presence or absence of some symmetry or correlation in a many-particle system.

In condensed matter physics, systems typically are ordered at low temperatures; upon heating, they undergo one or several phase transitions into less ordered states. Examples for such an order-disorder transition are:

The degree of freedom that is ordered or disordered can be translational (crystalline ordering), rotational (ferroelectric ordering), or a spin state (magnetic ordering).

The order can consist either in a full crystalline space group symmetry, or in a correlation. Depending on how the correlations decay with distance, one speaks of long-range order or short-range order.

If a disordered state is not in thermodynamic equilibrium, one speaks of quenched disorder. For instance, a glass is obtained by quenching (supercooling) a liquid. By extension, other quenched states are called spin glass, orientational glass. In some contexts, the opposite of quenched disorder is annealed disorder.

Order (biology)

In biological classification, the order (Latin: ordo) is

What does and does not belong to each order is determined by a taxonomist. Similarly for the question if a particular order should be recognized at all. Often there is no exact agreement, with different taxonomists each taking a different position. There are no hard rules that a taxonomist needs to follow in describing or recognizing an order. Some taxa are accepted almost universally, while others are recognised only rarely.

For some groups of organisms, consistent suffixes are used to denote that the rank is an order. The Latin suffix -(i)formes meaning "having the form of" is used for the scientific name of orders of birds and fishes, but not for those of mammals and invertebrates. The suffix -ales is for the name of orders of vascular plants.

Order of reaction

In chemical kinetics, the order of reaction with respect to a given substance (such as reactant, catalyst or product) is defined as the index, or exponent, to which its concentration term in the rate equation is raised. For the typical rate equation of form , where [A], [B], ... are concentrations, the reaction orders (or partial reaction orders) are x for substance A, y for substance B, etc. The overall reaction order is the sum x + y + .... For many reactions, the reaction orders are not equal to the stoechiometric coefficients.

For example, the chemical reaction between mercury (II) chloride and oxalate ion

has the observed rate equation

In this case, the reaction order with respect to the reactant HgCl₂ is 1 and with respect to oxalate ion is 2; the overall reaction order is 1 + 2 = 3. The reaction orders (here 1 and 2 respectively) differ from the stoichiometric coefficients (2 and 1). Reaction orders can be determined only by experiment. Their knowledge allows conclusions to be drawn about the reaction mechanism, and may help to identify the rate-determining step.
