Operation Sigma Sigma

The Sigma is an experimental glider developed in Britain from 1966 by a team led by Nicholas Goodhart. After disappointing performance during flight testing the Sigma was passed on to a Canadian group which carried out modifications, making the Sigma more competitive.

Design and development

Designed to compete in the 1970 World Championships, the team aimed to develop a wing that would climb well through a high lift coefficient and a large wing area, but equally had the "maximum possible reduction of area for cruise at low lift coefficients". At the same time for the minimum possible drag they aimed for "extensive" laminar flow. To achieve this they employed flaps that would alter both wing area and wing camber. Based on analysis of the nature of thermals encountered in cross-country flying, they reasoned that by having a slow turning circle, their sailplane could stay close to the central (and strongest) part of the thermal and gain maximum benefit.

Its unusual feature is its ability to vary its wing area using Fowler flaps. It had been tried before by the Hannover Akaflieg in 1938 with their AFH-4, the South African Beatty-Johl BJ-2 Assegai and the SZD Zefir gliders.

Sigma (cosmology)

Sigma in cosmology was a property of galaxies used when trying to work out the mystery of galaxies and their supermassive black holes.

History

In the late 1990s the NUKER experts had made observations with a spectroscope of two galaxies, one of an active galaxy with an active galactic nucleus called NGC10-68 and a dormant galaxy next door to us named Andromeda.

The observations are shown. The light from the centre in Andromeda galaxy was distorted proving the existence of super-massive black holes.

Other observations proved most galaxies had a similar centre whether it be active or dormant.

They then realised that the black holes must have something to do with a galaxy's formation, so they turned to something they thought was useless: the speed of the stars around the edge of the galaxy. This was Sigma, the speed of the stars at the edge of the galaxy supposedly unaffected by the mass of the black hole at the centre.

Usage In Cosmology

The NUKER team calculated the sigma of several stars in different galaxies and the mass of the black hole at the (nucleus) centre. They expected no correlation what so ever. But when plotting their results on a Scatter diagram and drawing a line of best fit they ended up with a positive correlation. It appeared that the heavier the black hole at the centre was the faster the stars within the galaxy travelled.

Sigma (duo)

Sigma is an English drum and bass duo consisting of Cameron Edwards and Joe Lenzie. They met at Leeds University at drum and bass nights. Their 2010 collaboration with DJ Fresh, "Lassitude", peaked at number 98 on the UK Singles Chart. Their single "Nobody to Love" topped the UK Singles Chart, becoming their first UK number one. Follow-up single "Changing", featuring Paloma Faith, also got to number one.

Career

Formation

Lenzie and Edwards met in 2006 at Leeds University; Cameron was working in local record store Tribe Records and with Echo Location's Obi running local night Event Horizon, while Lenzie was DJing hip-hop and warming up Event Horizon for such acts as Rahzel and Grandmaster Flash. Once they had finished in Leeds, they relocated to London and became a three-piece with Edwards' school friend Ben Mauerhoff, being signed under DJ Fresh's Breakbeat Kaos. After a while, long distances took their toll – Edwards and Mauerhoff were based in Surrey, whereas Lenzie was based in Harpenden, Hertfordshire and they couldn't get three people into the Harpenden studio – and Mauerhoff left. In December 2008 they formed their own record label, Life Recordings (so called because, according to Lenzie, the industry demanded that it be their life). Its inaugural release was a VIP mix of their early Bingo Beats single "El Presidente".

Messiah

A messiah (literally, "anointed one") is a saviour or liberator of a group of people, most commonly in the Abrahamic religions. In the Hebrew Bible, a messiah (Hebrew: מָשִׁיחַ, Modern mashiaẖ, Tiberian māšîăḥ) is a king or High Priest traditionally anointed with holy anointing oil. However, messiahs were not exclusively Jewish, as the Hebrew Bible refers to Cyrus the Great, king of Persia, as a messiah for his decree to rebuild the Jerusalem Temple.

The concept of messianism originated in Judaism. According to Jewish tradition, the Jewish Messiah, HaMashiach ( המשיח , "the Messiah", "the anointed one"), often referred to as "King Messiah" (מלך המשיח, melekh mashiach), is plainly distinct from the concept of a divine Christian Messiah or any other concept of a messiah in other Abrahamic religions, especially the Islamic. The future Jewish Messiah to come is thought to be a human leader, physically descended from the paternal Davidic line through King David and King Solomon. He is thought to accomplish predetermined things in only one future arrival, including the unification of the tribes of Israel, the gathering in of all Jews to Eretz Israel, the rebuilding of the Temple in Jerusalem, the ushering in of a Messianic Age of global universal peace, and the annunciation of the World to Come.

Messiah (Fear Factory album)

Messiah is a compilation album by American heavy metal band Fear Factory released in 1999 by Roadrunner Records. It includes one song from Soul of a New Machine, six from Demanufacture, two from Remanufacture and one from Obsolete. It is the soundtrack to the video game, Messiah.

Track listing

Messiah (Starling novel)

Messiah is a thriller novel by British writer Boris Starling, published in 1999. Following the success of the novel, a sequel, Storm (2000), was also released.

The novel became the basis for the popular BBC TV series Messiah, starring Ken Stott.

Plot summary

The novel opens with the discovery of the body of Philip Rhodes, a London caterer, who is found hanging in his underwear from his banister, his tongue cut out and a silver spoon in its place. When the body of the Bishop of Wandsworth, James Cunningham, is found beaten to death, but with his tongue replaced by a silver spoon, DCI Red Metcalfe and his team must discover the pattern behind these killings and save the rest of the men who are destined to be murdered. The novel has many twists and turns and it describes the killings in great detail adding to the intense atmosphere. Starling manages to create a novel which is difficult to put down and which explores the mind of a man who has thoughts of a higher being.
