Spiral

In mathematics, a spiral is a curve which emanates from a central point, getting progressively farther away as it revolves around the point.

Spirals and helices

Two major definitions of "spiral" in a respected American dictionary are:

Definition a describes a planar curve, that extends in both of the perpendicular directions within its plane; the groove on one side of a record closely approximates a plane spiral (and it is by the finite width and depth of the groove, but not by the wider spacing between than within tracks, that it falls short of being a perfect example); note that successive loops differ in diameter. In another example, the "center lines" of the arms of a spiral galaxy trace logarithmic spirals.

Definition b includes two kinds of 3-dimensional relatives of spirals:

Spiral (disambiguation)

Spiral (TV series)

Spiral (French: Engrenages, pronounced: [ɑ̃ɡʁəˈnaʒ]) is a French television police and legal drama series set in Paris. The show follows the lives and work of Paris police officers and the lawyers and judges who work at the Palais de Justice. It was created by the TV production company Son et Lumière.

The first series of eight-episodes started on Canal+ in France on 13 December 2005. The series was shown in the UK on BBC Four during the summer of 2006. It was the channel's first French-language drama series, attracting a modest but loyal audience (around 200,000) and firm critical approval. On 13 September 2009, BBC Four started showing the second series – another eight-part series, partly funded by the BBC – was broadcast from 12 May 2008. The third series was shown from 2 April 2011, and the fourth series from 9 February 2013 – both consisting of twelve episodes.

Series 5 was filmed in 2013 and broadcast in France in late 2014, and in the UK on BBC Four from 10 January 2015. The sixth series has been ordered.

Air (classical element)

Air (also sometimes called Wind) is often seen as a universal power or pure substance. Its fundamental importance to life can be seen in words such as aspire, inspire, perspire and spirit, all derived from the Latin spirare.

Greek and Roman tradition

Air is one of the four classical elements in ancient Greek philosophy and science. According to Plato, it is associated with the octahedron; air is considered to be both hot and wet. The ancient Greeks used two words for air: aer meant the dim lower atmosphere, and aether meant the bright upper atmosphere above the clouds.Plato, for instance writes that "So it is with air: there is the brightest variety which we call aether, the muddiest which we call mist and darkness, and other kinds for which we have no name...." Among the early Greek Pre-Socratic philosophers, Anaximenes (mid-6th century BCE) named air as the arche. A similar belief was attributed by some ancient sources to Diogenes Apolloniates (late 5th century BCE), who also linked air with intelligence and soul (psyche), but other sources claim that his arche was a substance between air and fire.Aristophanes parodied such teachings in his play The Clouds by putting a prayer to air in the mouth of Socrates.

Akeboshi

Yoshio Akeboshi (明星嘉男, Akeboshi Yoshio), more commonly known as Akeboshi, is a Japanese pop and folk singer. He is mainly known for the song "Wind". His surname means "bright star," while his given name means "fine man."

Akeboshi was born on July 1, 1978 in Yokohama. He learned to play the piano when he was three years old, later learning to play the guitar. He studied music in Liverpool, and his time there has heavily influenced his music. Before his major debut, he produced two of the songs on Matsu Takako's fourth album, A piece of life.

Albums

Akeboshi's debut album, Akeboshi, was released on June 22, 2005 on Epic Records Japan.

Most of these tracks are taken from the mini-albums, with some re-recorded in slightly different arrangements.
