Circle

A circle is a simple shape in Euclidean geometry. It is the set of all points in a plane that are at a given distance from a given point, the centre; equivalently it is the curve traced out by a point that moves so that its distance from a given point is constant. The distance between any of the points and the centre is called the radius.

A circle is a simple closed curve which divides the plane into two regions: an interior and an exterior. In everyday use, the term "circle" may be used interchangeably to refer to either the boundary of the figure, or to the whole figure including its interior; in strict technical usage, the circle is only the boundary and the whole figure is called a disk.

A circle may also be defined as a special ellipse in which the two foci are coincident and the eccentricity is 0, or the two-dimensional shape enclosing the most area per unit perimeter squared, using calculus of variations.

Terminology

Spirit

The English word spirit, from Latin spiritus "breath", has many different meanings and connotations, most of them relating to a non-corporeal substance contrasted with the material body. It can also refer to a "subtle" as opposed to "gross" material substance, as in the famous last paragraph of Sir Isaac Newton's Principia Mathematica.

The word spirit is often used metaphysically to refer to the consciousness or personality. The notions of a person's spirit and soul often also overlap, as both contrast with body and both are believed to survive bodily death in some religions, and "spirit" can also have the sense of "ghost", i.e. a manifestation of the spirit of a deceased person.

The term may also refer to any incorporeal or immaterial being, such as demons or deities. In the Bible, "the Spirit" (with a capital "S"), specifically denotes the Holy Spirit.

Etymology

The English word spirit comes from the Latin spiritus, meaning "breath", but also "spirit, soul, courage, vigor", ultimately from a Proto-Indo-European *(s)peis. It is distinguished from Latin anima, "soul" (which nonetheless also derives from an Indo-European root meaning "to breathe", earliest form *h₂enh₁- ). In Greek, this distinction exists between pneuma (πνεῦμα), "breath, motile air, spirit," and psykhē (ψυχή), "soul" (even though the latter term, ψῡχή = psykhē/psūkhē, is also from an Indo-European root meaning "to breathe": *bhes-, zero grade *bhs- devoicing in proto-Greek to *phs-, resulting in historical-period Greek ps- in psūkhein, "to breathe", whence psūkhē, "spirit", "soul").

Sacred Spirit

Sacred Spirit is a musical project by Claus Zundel, Ralf Hamm and Markus Staab. The music is of electronic, new age, world and ambient genres. Sacred Spirit's total worldwide album sales estimated to be over 15 million copies. For each album sold, a donation was made to the Native American Rights Fund, the non-profit Native American organization devoting all its time to restoring the legal rights of the native American people.

History

The first album, Chants and Dances of the Native Americans was released in 1994. The album was nominated for best New Age album Grammy Award. In keeping with the Native American theme, Zundel adopted the pseudonym 'The Fearsome Brave', and on his many other projects he is simply credited as 'The Brave'. The music conveys the stories, legends and plight of the Native Americans by combining sampled chants of the Navajo, Pueblo and Sioux tribes and Sami people yoik with synthesizer backings, all driven forth by a combination of traditional drumming and electronic dance-beats. The first single released off the album was "Yeha-Noha" (Wishes of happiness and prosperity) which was largely responsible for catapulting Sacred Spirit into the limelight. The single reached #1 position in number of countries, including 6 weeks at #1 in France. In the US, "Yeha Noha" sung by Navajo elder Kee Chee Jake of Chinle, Arizona reached top 20 in Billboard Hot 100. The album is arguably one of the most successful enigmatic projects ever, garnering sales of more than seven million albums worldwide. It reached top 10 and charted for twenty seven weeks in the UK Albums Chart.

Circle dance

Circle dance, or chain dance, is a style of dance done in a circle or semicircle to musical accompaniment, such as rhythm instruments and singing. Circle dancing is probably the oldest known dance formation and was part of community life from when people first started to dance.

Dancing in a circle is an ancient tradition common to many cultures for marking special occasions, rituals, strengthening community and encouraging togetherness. The dance can also be enjoyed as an uplifting group experience or as part of a meditation. Circle dances are choreographed to many different styles of music and rhythms.

Unlike line dancing, circle dancers are in physical contact with each other; the connection is made by hand-to-hand, finger-to-finger or hands-on-shoulders. It is a type of dance where anyone can join in without the need of partners. Generally, the participants follow a leader around the dance floor while holding the hand of the dancers beside them. The dance can be gentle or energetic.

Trousers

Trousers (pants in North America) are an item of clothing worn from the waist to the ankles, covering both legs separately (rather than with cloth extending across both legs as in robes, skirts, and dresses).

In the UK the word "pants" generally means underwear and not trousers.Shorts are similar to trousers, but with legs that come down only to around the area of the knee, higher or lower depending on the style of the garment. To distinguish them from shorts, trousers may be called "long trousers" in certain contexts such as school uniform, where tailored shorts may be called "short trousers", especially in the UK.

In most of the Western world, trousers have been worn since ancient times and throughout the Medieval period, becoming the most common form of lower-body clothing for adult males in the modern world, although shorts are also widely worn, and kilts and other garments may be worn in various regions and cultures. Breeches were worn instead of trousers in early modern Europe by some men in higher classes of society. Since the mid-20th century, trousers have increasingly been worn by women as well. Jeans, made of denim, are a form of trousers for casual wear, now widely worn all over the world by both sexes. Shorts are often preferred in hot weather or for some sports and also often by children and teenagers. Trousers are worn on the hips or waist and may be held up by their own fastenings, a belt or suspenders (braces). Leggings are form-fitting trousers, of a clingy material, often knitted cotton and spandex (elastane).
