Dynamics

Every object experiences some form of motion which is the result of different forces acting on the object. Dynamics is the study of the forces which are responsible for this motion. Dynamics (from Greek δυναμικός dynamikos "powerful", from δύναμις dynamis "power") may refer to:

Rigid body dynamics

Rigid-body dynamics studies the movement of systems of interconnected bodies under the action of external forces. The assumption that the bodies are rigid, which means that they do not deform under the action of applied forces, simplifies the analysis by reducing the parameters that describe the configuration of the system to the translation and rotation of reference frames attached to each body. This excludes bodies that display fluid highly elastic, and plastic behavior.

The dynamics of a rigid body system is described by the laws of kinematics and by the application of Newton's second law (kinetics) or their derivative form Lagrangian mechanics. The solution of these equations of motion provides a description of the position, the motion and the acceleration of the individual components of the system and overall the system itself, as a function of time. The formulation and solution of rigid body dynamics is an important tool in the computer simulation of mechanical systems.

Dynamic (record label)

Dynamic is an Italian independent record label located in Genoa. Founded in 1978, it specialises in classical music and opera, especially rarely performed works and has produced several world premiere recordings. The Dynamic catalogue contains over 400 titles, with about 25 new titles added each year and is distributed in 32 countries.

History

Dynamic was founded in 1978 by Pietro Mosetti Casaretto and his wife Marisa. Mosetti Casaretto, a surgeon and amateur violinist, took over a small label founded by the musicologist Edward Neill. In the beginning, Dynamic was a small family business. Mosetti Casaretto and his wife recorded in local churches, oratories and villas. The first recordings were issued on vinyl, the very first one being Paganini's Barucabà Variations played by Salvatore Accardo.

In 1985 the company moved to its current site in the Villa Quartana on the Righi hill overlooking Genoa, where it set up a recording hall that could house a small chamber orchestra. In the late 1990s Mosetti Casaretto retired, and management of the label was taken over by his son-in-law, Alberto Dellepiane. Over the years, the label's focus on chamber music and particularly violin music has widened to include full-length opera recordings on both CD and DVD. More recently, Dynamic has become a high definition content producer for television and cinema.

Student

A student or pupil is a learner, or someone who attends an educational institution. In Britain until about 2012, underage schoolchildren were always referred to as "pupils", while those attending university are termed "students". In the USA, and more recently also in Britain, the term "student" is applied to both categories, no doubt due to US influence. In its widest use, student is used for anyone who is learning, including mid-career adults who are taking vocational education or returning to university, or younger 'researchers or artists learning from a more experienced (and usually older) colleague and mentor.

Asia

Singapore

Education can be Government initiated and compulsory for students from the age of 6 to the age of 16. Primary School (Primary 1 to 6) Secondary School ( Secondary 1 to 4 or 5) Junior College (Junior College 1 to 2 - Optional)

There are also schools which has the integrated programme such as River Valley High School (Singapore).

International Schools are subject to overseas curriculums such as the British, American, Canadian or Australian Boards.

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.
