Different (Thomas Anders album)

Different is debut solo-album released in 1989 by Thomas Anders, who first attained success as the lead vocalist for Modern Talking in the mid-'80s. The album was recorded in London at Alan Parsons' studio and was produced by Gus Dudgeon (Elton John) & Alan Tarney (a-ha). It features a cover of Chris Rea's Fool (If You Think It's Over).

It's an extravagant album, featuring a legion of songwriters and session musicians. The album boasted the hit Love Of My Own and became a big success for Anders. Other singles were Soldier and One Thing.

The album was re-released twice by EastWest Records in 1991 and 1998.

Track listing

Different (Robbie Williams song)

"Different" is a song by English singer-songwriter Robbie Williams, taken from his ninth studio album, Take the Crown. It was released as the album's second single on 17 December 2012. The song was written by Williams, Gary Barlow and Jacknife Lee. The single was accompanied by four extra tracks: "On My Own", a duet with Tom Jones, "Soul Transmission", "White Man in Hanoi", a cut from Take the Crown, and "The Promise", a cover from singer songwriter Paul Freeman (Robbie's Christmas song).

Background

"Different" was produced by Jacknife Lee, who said of the track: "I think when Robbie gets a song right, it's the vulnerability mixed with the bravado that makes it so compelling", to which Robbie replied, "It's the great hope of the second single variety. A lot of effort went into this song, which is a very personal statement". Williams also commented on the number of B-sides released with the single: "I write so many songs and I love all of them, but they don't all make it onto a record. Some of my favourite songs have never been heard. I wanted to put out an EP so a few more could be heard. Check out the legend that is Tom Jones on 'On My Own'. 'The Promise' is my Christmas song." Digital versions of the single available in Germany contain a bonus live recording of "Different", featuring vocals from co-songwriter Gary Barlow, who performed the track live with Williams on 23 November 2012, at the O2 Arena in London.

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".
