Map

A map is a symbolic depiction highlighting relationships between elements of some space, such as objects, regions, and themes.

Many maps are static two-dimensional, geometrically accurate (or approximately accurate) representations of three-dimensional space, while others are dynamic or interactive, even three-dimensional. Although most commonly used to depict geography, maps may represent any space, real or imagined, without regard to context or scale; e.g. brain mapping, DNA mapping and extraterrestrial mapping.

Although the earliest maps known are of the heavens, geographic maps of territory have a very long tradition and exist from ancient times. The word "map" comes from the medieval Latin Mappa mundi, wherein mappa meant napkin or cloth and mundi the world. Thus, "map" became the shortened term referring to a two-dimensional representation of the surface of the world.

Geographic maps

Cartography or map-making is the study and practice of crafting representations of the Earth upon a flat surface (see History of cartography), and one who makes maps is called a cartographer.

Maps (Maroon 5 song)

"Maps" is a song by American band Maroon 5. The song was released on June 16, 2014, as the lead single from their fifth studio album V.

Composition

The song was written by Adam Levine, Ammar Malik, Ryan Tedder, Benny Blanco and Noel Zancanella, and produced by the latter three. Blanco and Malik have previously teamed with Maroon 5 on the songs "Moves like Jagger" and "Payphone", while Tedder and Zancanella have worked with the group on the songs "Love Somebody" and "Lucky Strike". "Maps" is an up-tempo pop track, composed in the key of C# minor (with the main chord progression of A–B–C#m - both in the verses and the chorus - and F#m–G#m-G#7 in the pre-chorus), that contains a "breezy guitar lick". It marks Maroon 5's further departure from the funkier sound for which the band was originally known. The official remix features a new verse from Big Sean and new production beats.

Lyrically, the song is about "the search for love, particularly a love that has been lost and needs to be found". In the chorus, Adam Levine sings "All the roads you took came back to me / So I'm following the map that leads to you."

Get Cape. Wear Cape. Fly

Sam Duckworth is an English musician formerly known as Get Cape. Wear Cape. Fly. He is sometimes referred to as Get Cape, Cape, GCWCF and Slam Dunkworth (the latter title apparently first coined by Emmy The Great). According to Duckworth, his stage name comes from Retro Gamer magazine, from an article about superhero games such as Batman containing the heading "Get Cape. Wear Cape. Fly".

Music career

Sam grew up in Southend-on-Sea, Essex. Get Cape was signed to Atlantic Records in March 2006, after playing many gigs, both with punk rock band Silverskin and as Get Cape. As Get Cape, Duckworth has collaborated with Billy Bragg, Nitin Sawhney, Shlomo, Killa Kela, Baba Maal, Flea, Kate Nash, and many others with his participation in many events for Africa Express.

Sam co-organised The Demolition Ball - the last night at the London Astoria venue before it was knocked down in January 2009. Get Cape also headlined the Astoria for his 21st birthday party.

After 10 years, Sam Duckworth decided to end Get Cape. Wear Cape. Fly, to continue to make music under his own name. The last ever show under the 'Get Cape' moniker was held at The Forum, Kentish Town on 12 September 2014.

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".
