Apparent Magnitude
Apparent magnitude () is a measure of the brightness of a star or other astronomical object observed from Earth. An object's apparent magnitude depends on its intrinsic luminosity, its distance from Earth, and any extinction of the object's light caused by interstellar dust along the line of sight to the observer. The word ''magnitude'' in astronomy, unless stated otherwise, usually refers to a celestial object's apparent magnitude. The magnitude scale dates back to the ancient Roman astronomer Claudius Ptolemy, whose star catalog listed stars from 1st magnitude (brightest) to 6th magnitude (dimmest). The modern scale was mathematically defined in a way to closely match this historical system. The scale is reverse logarithmic: the brighter an object is, the lower its magnitude number. A difference of 1.0 in magnitude corresponds to a brightness ratio of \sqrt /math>, or about 2.512. For example, a star of magnitude 2.0 is 2.512 times as bright as a star of magnitude 3.0, ...

Apparent Places
The apparent place of an object is its position in space as seen by an observer. Because of physical and geometrical effects it may differ from the "true" or "geometric" position. Astronomy In astronomy, a distinction is made between the ''mean position'', ''apparent position'' and ''topocentric position'' of an object. Position of a star The mean position of a star (relative to the observer's adopted coordinate system) can be calculated from its value at an arbitrary epoch, together with its actual motion over time (known as proper motion). The ''apparent position'' is its position as seen by a theoretical observer at the centre of the moving Earth. Several effects cause the apparent position to differ from the mean position: * Annual aberration – a deflection caused by the velocity of the Earth's motion around the Sun, relative to an inertial frame of reference. This is independent of the distance of the star from the Earth. * Annual parallax – the apparent change in p ...

Heir Apparent
An heir apparent, often shortened to heir, is a person who is first in an order of succession and cannot be displaced from inheriting by the birth of another person; a person who is first in the order of succession but can be displaced by the birth of a more eligible heir is known as heir presumptive. Today these terms most commonly describe heirs to hereditary titles (e.g. titles of nobility) or offices, especially when only inheritable by a single person. Most monarchies refer to the heir apparent of their thrones with the descriptive term of ''crown prince'' or ''crown princess'', but they may also be accorded with a more specific substantive title: such as Prince of Orange in the Netherlands, Duke of Brabant in Belgium, Prince of Asturias in Spain (also granted to heirs presumptive), or the Prince of Wales in the United Kingdom; former titles include Dauphin in the Kingdom of France, and Tsesarevich in Imperial Russia. The term is also used metaphorically to indica ...

Apparent Death
Apparent death, colloquially known as playing dead, feigning death, or playing possum, is a behavior in which animals take on the appearance of being dead. It is an immobile state most often triggered by a predatory attack and can be found in a wide range of animals from insects and crustaceans to mammals, birds, reptiles, amphibians, and fish. Apparent death is also referred to as thanatosis, animal hypnosis, immobilization catatonia, or tonic immobility, the latter of which is preferred in the scientific literature on the subject. Apparent death is separate from the freezing behavior seen in some animals. Apparent death is a form of animal deception considered to be an anti-predator strategy, but it can also be used as a form of aggressive mimicry. When induced by humans, the state is sometimes colloquially known as animal hypnosis. The earliest written record of "animal hypnosis" dates back to the year 1646 in a report by Athanasius Kircher, in which he subdued chickens. D ...

Apparent Wind
Apparent wind is the wind experienced by a moving object. Definition of apparent wind The ''apparent wind'' is the wind experienced by an observer in motion and is the relative velocity of the wind in relation to the observer. The ''velocity of the apparent wind'' is the vector sum of the ''velocity of the headwind'' (which is the velocity a moving object would experience in still air) plus the ''velocity of the true wind''. The headwind is the additive inverse of the object's velocity; therefore, the ''velocity of the apparent wind'' can also be defined as a vector sum of the ''velocity of the true wind'' minus the ''velocity of the object''. Apparent wind in sailing In sailing, ''apparent wind'' is the speed and direction of wind indicated by a wind instrument ( anemometer) on a ''moving'' craft (on water, land or ice) in undisturbed air. It is composed of the ''combined'' speeds and directions of the craft and wind observed by a ''stationary'' wind instrument—the ''true ...

Eire Apparent
Eire Apparent were a band from Northern Ireland, noted for launching the careers of Henry McCullough and Ernie Graham, and for having Jimi Hendrix play on, and produce, their only album. History Tony and The Telstars The origins of the group stretch back to early '60s Belfast band Tony & The Telstars, which featured lead guitarist Rod Demick (born Roderick Demick, 1947, Prestatyn, Flintshire, North Wales), drummer Davy Lutton (born William David Lutton, 1946, Belfast), lead vocalist and guitarist George O'Hara and bassist Chris Stewart (born Eric Christopher Stewart, 1946, Belfast, Co Antrim). During 1965, Demick departed to join local R'n'B group The Wheels and Stewart joined German-based Irish band The Stellas. Their replacements included guitarist David "Tiger" Taylor, bassist Mike Niblett (from The Stellas) and apprentice auto mechanic Ernie Graham (born Ernest Harold Graham, 14 June 1946, Belfast) on rhythm guitar and backing vocals.
