Promises (Take That song)
"Promises" is an pop–dance song by boy band Take That. It was written by Gary Barlow and was the second release from Take That's debut album, Take That & Party.
Song information
Written by Gary Barlow and Graham Stack, it was released on 18 November 1991 as the second single from the band's debut album, Take That & Party (1992). It was a modest success, charting at number 38 on the UK Singles Chart.
Music video
The music video uses intercut clips of the band performing and rehearsing as well as showing the hysteria of Take That's fans. It also shows a half-naked band member, unknown at the time, jumping out of a swimming pool. This was later confirmed to be Robbie Williams during an interview.

Unstable (album)
Unstable is Adema's second and also final album to feature its original lineup with vocalist Mark Chavez departing from the band after its release and then again after their reunion. It was released on August 12, 2003. It has sold about 400,000 copies worldwide. Its radio single was the self-titled song "Unstable", which also had a music video, but it didn't get very much radio play. Many songs relied more on instrumentation and harmony instead of distortion in comparison to their previous album, but the album also has some of the band's most aggressive work. It was less successful than their first album, debuting at number 43 on the Billboard 200 before quickly falling off the chart.

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.
