Plant

Plants, also called green plants, are multicellular eukaryotes of the kingdom Plantae. They form an unranked clade Viridiplantae (Latin for green plants) that includes the flowering plants, conifers and other gymnosperms, ferns, clubmosses, hornworts, liverworts, mosses and the green algae. Green plants excludes the red and brown algae, the fungi, archaea, bacteria and animals.

Green plants have cell walls with cellulose and obtain most of their energy from sunlight via photosynthesis by primary chloroplasts, derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic and have lost the ability to produce normal amounts of chlorophyll or to photosynthesize. Plants are also characterized by sexual reproduction, modular and indeterminate growth, and an alternation of generations, although asexual reproduction is also common.

Precise numbers are difficult to determine, but as of 2010, there are thought to be 300–315 thousand species of plants, of which the great majority, some 260–290 thousand, are seed plants (see the table below). Green plants provide most of the world's molecular oxygen and are the basis of most of the earth's ecologies, especially on land. Plants that produce grains, fruits and vegetables form mankind's basic foodstuffs, and have been domesticated for millennia. Plants are used as ornaments and, until recently and in great variety, they have served as the source of most medicines and drugs. The scientific study of plants is known as botany, a branch of biology.

Plantà

The plantá (which comes from the verb to plant; in Valencian, plantà) is the act of erecting a Falla or bonfire monument, in the Fallas or the Bonfires of Saint John, festivals held respectively in March and June in different localities of the Community of Valencia (Spain).The plantà is currently considered the exact moment when the falla or bonfire is completely finished and ready to be visited, with all its “ninots” (human figures made of combustible materials, such as cardboard or wood, which has a critical or mocking nature), posters and a variety of features (lights, matted grass, interpretive signs...).

In the Fallas of Valencia, the plantá takes place on March 15, when all the Falla monuments must be positioned correctly. The reason is that the jury appointed by the Central Fallera committee has to go to the next day to assess the falla. Formerly, the plantà began and ended the same day but, due to the complexity of the monuments and the fact that the makers of Fallas are responsible for several Fallas monuments at the same time, it usually begins a few days before. The burning of the Falla or cremá is carried out four days later, on the night of March 19.

The Student (newspaper)

The Student is a weekly British independent newspaper produced by students at the University of Edinburgh. It held the title of Best Student Newspaper in Scotland, awarded by the Herald Student Press Awards in 2006, 2007, 2009 and 2010. It was founded in 1887 by Robert Louis Stevenson making it the UK's oldest student newspaper.

The newspaper has been independent of the university since 1992, but maintains a commercial agreement with the Edinburgh University Students' Association.

All staff are volunteers, who fit work for the newspaper around their studies. The newspaper is distributed on a Tuesday and usually consists of 32 pages. It has a physical circulation of 4,000 copies per issue and is read by some 30,000 people in Edinburgh.

History

The Student started as a small weekly magazine, published by the Students' Representative Council. A typical, turn-of-the-century edition of The Student would open with a short biography of a notable person and an editorial. The remaining content largely comprised notes from various societies, sports results, poetry and literary reviews, and profiles of newly appointed lecturers. The magazine was supported by advertising, but cost two pence.

William Sealy Gosset

William Sealy Gosset (13 June 1876 – 16 October 1937) was an English statistician. He published under the pen name Student, and developed the Student's t-distribution.

Life and career

Born in Canterbury, England to Agnes Sealy Vidal and Colonel Frederic Gosset, Gosset attended Winchester College before reading chemistry and mathematics at New College, Oxford. Upon graduating in 1899, he joined the brewery of Arthur Guinness & Son in Dublin, Ireland.

As an employee of Guinness, a progressive agro-chemical business, Gosset applied his statistical knowledge – both in the brewery and on the farm – to the selection of the best yielding varieties of barley. Gosset acquired that knowledge by study, by trial and error, and by spending two terms in 1906–1907 in the biometrical laboratory of Karl Pearson. Gosset and Pearson had a good relationship. Pearson helped Gosset with the mathematics of his papers, including the 1908 papers, but had little appreciation of their importance. The papers addressed the brewer's concern with small samples; biometricians like Pearson, on the other hand, typically had hundreds of observations and saw no urgency in developing small-sample methods.
