Minute and second of arc

A minute of arc (MOA), arcminute (arcmin) or minute arc is a unit of angular measurement equal to one-sixtieth (1/60) of one degree. As one degree is 1/360 of a circle, one minute of arc is 1/21600 of a circle (or, in radians, π/10800). It is used in fields that involve very small angles, such as astronomy, optometry, ophthalmology, optics, navigation, land surveying and marksmanship.

The number of square arcminutes in a complete sphere is approximately 148,510,660 square arcminutes.

A second of arc (arcsecond, arcsec) is 1/60 of an arcminute, 1/3,600 of a degree, 1/1,296,000 of a circle, and π/648,000 (about 1/206,265) of a radian. This is approximately the angle subtended by a U.S. dime coin (18mm) at a distance of 4 kilometres (about 2.5 mi).

To express even smaller angles, standard SI prefixes can be employed; the milliarcsecond (mas), for instance, is commonly used in astronomy.

Symbols and abbreviations

The standard symbol for marking the arcminute is the prime (′) (U+2032), though a single quote (') (U+0027) is commonly used where only ASCII characters are permitted. One arcminute is thus written 1′. It is also abbreviated as arcmin or amin or, less commonly, the prime with a circumflex over it ().

And Their Name Was Treason

And Their Name Was Treason is the debut studio album by American rock band A Day to Remember, released on May 10, 2005 through Indianola Records. It followed their self-released EP, which was produced the previous year. The album was the band's only release under Indianola; its success led the group sign to Victory Records. Several songs on the album were written during the band members' teenage years. Recorded in the producer's bedroom, the album contains audio excerpts from several films. The band toured in the United States to help promote the album. The album has since sold over 10,000 copies. A re-recorded version of the album, titled Old Record, was released in October 2008 by Victory. The band members later admitted that they were forced to do the re-recording at the request of label owner Tony Brummel. The reissue charted at number 16 on the Heatseekers Album Chart in the U.S.

Background

A Day to Remember formed when guitarist Tom Denney asked Jeremy McKinnon if he would like to join the band as a vocalist. The pair hung out with drummer Bobby Scruggs, who later joined the band. During this period, both Denney and Scruggs were already in a band; Denney was in 2 Days 2 Late, while McKinnon played in All for Nothing. The trio wrote a song which McKinnon said "was better than everything our other bands had come up with". Shortly afterwards the trio decided to form a band which was called End of An Era in its first week of existence. The name was inspired by a movie listing in a TV guide found in Denney's home. One day at rehearsal, a friend of Scruggs showed up with his girlfriend, who came up with the band's name A Day to Remember.

List of craters on Mars: A-G

This is a list of craters on Mars. There are hundreds of thousands of impact craters on Mars, but only some of them have names. This list here only contains named Martian craters starting with the letter A – G (see also lists for H – N and O – Z).

Large Martian craters (greater than 60 km in diameter) are named after famous scientists and science fiction authors; smaller ones (less than 60 km in diameter) get their names from towns on Earth. Craters cannot be named for living people, and small crater names are not intended to be commemorative - that is, a small crater isn't actually named after a specific town on Earth, but rather its name comes at random from a pool of terrestrial place names, with some exceptions made for craters near landing sites. Latitude and longitude are given as planetographic coordinates with west longitude.

Illusion

An illusion is a distortion of the senses, revealing how the brain normally organizes and interprets sensory stimulation. Though illusions distort reality, they are generally shared by most people. Illusions may occur with any of the human senses, but visual illusions (optical illusions), are the most well-known and understood. The emphasis on visual illusions occurs because vision often dominates the other senses. For example, individuals watching a ventriloquist will perceive the voice is coming from the dummy since they are able to see the dummy mouth the words. Some illusions are based on general assumptions the brain makes during perception. These assumptions are made using organizational principles (e.g., Gestalt theory), an individual's capacity for depth perception and motion perception, and perceptual constancy. Other illusions occur because of biological sensory structures within the human body or conditions outside of the body within one’s physical environment.

The term illusion refers to a specific form of sensory distortion. Unlike a hallucination, which is a distortion in the absence of a stimulus, an illusion describes a misinterpretation of a true sensation. For example, hearing voices regardless of the environment would be a hallucination, whereas hearing voices in the sound of running water (or other auditory source) would be an illusion.

Faith Hill

Faith Hill (born Audrey Faith Perry; September 21, 1967) is an American country pop singer and occasional actress. She is one of the most successful country artists of all time, having sold more than 40 million albums worldwide. Hill is married to country singer Tim McGraw, with whom she has recorded several duets.

Hill's first two albums, Take Me as I Am (1993) and It Matters to Me (1995), were major successes and placed a combined three number ones on Billboard's country charts. She then achieved mainstream and crossover success with her next two albums, Faith (1998) and Breathe (1999). Faith spawned her first international hit, "This Kiss", and went multi-platinum in various countries. Breathe became her best-selling album to date and one of the best-selling country albums of all time, with the huge crossover success of the songs "Breathe" and "The Way You Love Me". It had massive sales worldwide and earned Hill three Grammy Awards, including Best Country Album.

In 2001, she recorded "There You'll Be" for the Pearl Harbor soundtrack and it became an international hit and her best-selling single in Europe. Hill's next two albums, Cry (2002) and Fireflies (2005), were both commercial successes and kept her mainstream popularity; the former spawned another crossover single, "Cry", which won Hill a Grammy Award, and the latter produced the hit singles "Mississippi Girl" and "Like We Never Loved at All", which earned her another Grammy Award.
