Audioslave (album)

Audioslave is the eponymous debut studio album by the American rock supergroup Audioslave and was released on November 19, 2002 (see 2002 in music). It features the hit singles "Cochise", "Show Me How to Live", "What You Are", "Like a Stone", and "I Am the Highway". The record was certified triple platinum in the US. "Like a Stone" was nominated for the 2004 Grammy Award for Best Hard Rock Performance.

Background

Audioslave was formed after Zack de la Rocha left Rage Against the Machine and the remaining members were searching for another vocalist. Producer and friend Rick Rubin suggested that they contact Chris Cornell. Rubin played the remaining Rage Against the Machine band members the Soundgarden song "Slaves & Bulldozers" to showcase his ability. Cornell was in the writing process of a second solo album, but decided to shelve that and pursue the opportunity to work with Tom Morello, Tim Commerford and Brad Wilk when they approached him. Morello described Cornell: "He stepped to the microphone and sang the song and I couldn't believe it. It didn't just sound good. It sounded transcendent. And... when there is an irreplaceable chemistry from the first moment, you can't deny it." The quartet wrote 21 songs during 19 days of rehearsal and began working in the studio in late May 2001.

Hypnotize (System of a Down song)

"Hypnotize" is the lead single for Armenian American rock band System of a Down's album of the same name, which was released on November 22, 2005 (see 2005 in music). The video was filmed on September 28, 2005, at the Van Andel Arena in Grand Rapids, Michigan. It reached number one on Billboard's Hot Modern Rock Tracks chart and is the band's biggest international hit.

As in many Mezmerize/Hypnotize songs, guitarist Daron Malakian accompanies Serj Tankian in the vocal sections. Serj and Daron perform a harmony in the refrain before and after the instrumental bridge. The combination of the two vocalists gives the song a vocal range, with Serj handling the lower verses and Daron handling the higher verses. Musically, "Hypnotize" changes modes in several places. The opening guitar riff and early verses are an upbeat melody that switches between the I (melodic) and V (Hindu) modes of F# melodic minor. The later riffs and the outro to the song are in the more commonly heard VI (natural) mode of F# minor. This mixing of modes creates the song's characteristic psychedelic feeling.

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".
