Team Fortress 2

Team Fortress 2 is a team-based first-person shooter multiplayer video game developed and published by Valve Corporation. It is the sequel to the 1996 mod Team Fortress for Quake and its 1999 remake. It was released as part of the video game compilation The Orange Box on October 10, 2007 for Windows and the Xbox 360. A PlayStation 3 version followed on December 11, 2007. On April 8, 2008, it was released as a standalone title for Windows. The game was updated to support OS X on June 10, 2010, and Linux on February 14, 2013. It is distributed online through Valve's download retailer Steam; retail distribution was handled by Electronic Arts.

In Team Fortress 2, players join one of two teams comprising nine character classes, battling in a variety of game modes including capture the flag and king of the hill. The development is led by John Cook and Robin Walker, creators of the original Team Fortress. Announced in 1998, the game once had more realistic, militaristic visuals and gameplay, but this changed over the protracted nine-year development. After Valve released no information for six years, Team Fortress 2 regularly featured in Wired News' annual vaporware list among other ignominies. The finished Team Fortress 2 has cartoon-like visuals influenced by the art of J. C. Leyendecker, Dean Cornwell and Norman Rockwell and is powered by Valve's Source engine.

Heavy (aeronautics)

The term heavy is used, with exceptions noted below, during all radio transmissions between air traffic control and any aircraft which has been assigned a maximum takeoff weight (MTOW) rating of 136 tonnes (300,000 lb) or more. Aircraft with a MTOW rating between 7 t and 136 t are considered medium and aircraft with a MTOW rating less than 7 t are considered light. In the US, the FAA uses a slightly different categorization. Aircraft capable of maximum takeoff weights more than 41,000 pounds (19,000 kg) and less than 300,000 pounds are considered large.

Such "heavy" aircraft over 136 t create wake turbulence from the wings. The term is mostly used around airports during take off and landing, incorporated into their call sign so as to warn other aircraft that they need extra distance to avoid this wake turbulence. All wide-body aircraft, except for the Airbus A300B1 (MTOW of 291,000 pounds (132,000 kg), only two built and retired in 1990) and the Airbus A380 and Antonov An-225 (which are classified in the even larger category of super), are thus classified as heavy. Certain variants of the narrow-bodied Boeing 707 and Douglas DC-8 also were considered "heavy" based on MTOW.

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".

As If (album)

As If is the sixth studio album by American dance-punk group !!!, released on October 16, 2015 on Warp Records.

Singles

Three official singles have been released from As If: "All U Writers", a 5 1/2 minute (5 minutes on the album) long song featuring vocals from Teresa Eggers, released 28 April 2015.

A lyric video for "Freedom '15" was uploaded 20 August 2015. The third single from the album, "Bam City", was released 30 September 2015, with an accompanying music video. "Ooo", a grooving love song, was released with an accompanying music video on November 16, 2015.

Critical Reception

In a positive review for Exclaim!, Daniel Sylvester called the album "one of the most enjoyable, if schizophrenic, dance albums of the year."
