Random information on the term “ERA”:

In baseball statistics, earned run average (ERA) is the mean of earned runs given up by a pitcher per nine innings pitched (i.e. the traditional length of a game). It is determined by dividing the number of earned runs allowed by the number of innings pitched and multiplying by nine. Runs resulting from defensive errors (including pitchers’ defensive errors) are recorded as unearned runs and omitted from ERA calculations.

Henry Chadwick is credited with devising the statistic, which caught on as a measure of pitching effectiveness after relief pitching came into vogue in the 1900s. Prior to 1900 – and, in fact, for many years afterward – pitchers were routinely expected to pitch a complete game, and their win-loss record was considered sufficient in determining their effectiveness.

After pitchers like James Otis Crandall and Charley Hall made names for themselves as relief specialists, gauging a pitcher’s effectiveness became more difficult using the traditional method of tabulating wins and losses. Some criterion was needed to capture the apportionment of earned-run responsibility for a pitcher in games that saw contributions from other pitchers for the same team. Since pitchers have primary responsibility to put opposing batters out, they must assume responsibility when a batter they do not retire at the plate moves to base, and eventually reaches home, scoring a run. A pitcher is assessed an earned run for each run scored by a batter (or that batter’s pinch-runner) who reaches base while batting against that pitcher. The National League first tabulated official earned run average statistics in 1912 (the outcome was called “Heydler’s statistic” for a while, after then-NL secretary John Heydler), and the American League later accepted this standard and began compiling ERA statistics.

Random information on the term “AGE”:

Ageing or aging (see spelling differences), is the process of becoming older. The term refers especially to human beings, many animals, and fungi, whereas for example bacteria, perennial plants and some simple animals are potentially immortal. In the broader sense, ageing can refer to single cells within an organism which have ceased dividing (cellular senescence) or to the population of a species (population ageing).

In humans, ageing represents the accumulation of changes in a human being over time, encompassing physical, psychological, and social changes. Reaction time, for example, may slow with age, while knowledge of world events and wisdom may expand. Ageing is among the greatest known risk factors for most human diseases: of the roughly 150,000 people who die each day across the globe, about two thirds die from age-related causes.

The causes of ageing are uncertain; current theories are assigned to the damage concept, whereby the accumulation of damage (such as DNA oxidation) may cause biological systems to fail, or to the programmed ageing concept, whereby internal processes (such as DNA methylation) may cause ageing. Programmed ageing should not be confused with programmed cell death (apoptosis).

Random information on the term “EON”:

The geologic time scale (GTS) is a system of chronological dating that relates geological strata (stratigraphy) to time, and is used by geologists, paleontologists, and other Earth scientists to describe the timing and relationships of events that have occurred during Earth’s history. The table of geologic time spans, presented here, agrees with the nomenclature, dates and standard color codes set forth by the International Commission on Stratigraphy.

Evidence from radiometric dating indicates that Earth is about 4.54 billion years old. The geology or deep time of Earth’s past has been organized into various units according to events which took place in each period. Different spans of time on the GTS are usually marked by changes in the composition of strata which correspond to those, and indicate major geological or paleontological events, such as mass extinctions. For example, the boundary between the Cretaceous period and the Paleogene period is defined by the Cretaceous–Paleogene extinction event, which marked the demise of the non-avian dinosaurs and many other groups of life. Older time spans, which predate the reliable fossil record (before the Proterozoic eon), are defined by their absolute age.

Random information on the term “SPAN”:

A span is the distance measured by a human hand, from the tip of the thumb to the tip of the little finger. In ancient times, a span was considered to be half a cubit. Sometimes the distinction is made between the great span (thumb to little finger) and little span (index finger to little finger).

Ancient Greek texts show that the span was used as a fixed measure in ancient Greece since at least archaic period. The word spithame (Greek: “σπιθαμή”), “span”, is attested in the work of Herodotus in the 5th century BC; however, the span was used in Greece long before that, since the word trispithamos (Greek: “τρισπίθαμος”), “three spans long”, occurs as early as the 8th century BC in Hesiod.

In Arabic, the analogue of the great span is the šibr (شبر). It is used in Modern Standard Arabic and classical Arabic, as well as in modern-day dialects.

In Slavic languages, the analogue of the span is various words derived from Proto-Slavic *pędь (Bulgarian педя, Polish piędź, Russian пядь, Slovenian ped, etc.). In various Slavic languages it is the distance from the tip of the thumb to the tip of the little finger or index finger. For example, Slovenian velika ped = great span (23 cm), mala ped = little span (9.5 cm); Russian piad = 4 vershoks = 17.8 cm. See Obsolete Russian weights and measures.

Random information on the term “AEON”:

Æon Flux is a 2005 American science fiction spy action film based on the animated science fiction television series of the same name created by Peter Chung. It was directed by Karyn Kusama, written by Phil Hay and Matt Manfredi, and produced by Gale Anne Hurd, David Gale, Gary Lucchesi and Greg Goodman. The film was produced by MTV Films, Lakeshore Entertainment, Babelsberg Film Studio and Valhalla Motion Pictures. It stars Charlize Theron as the title character, Marton Csokas, Jonny Lee Miller, Sophie Okonedo, Pete Postlethwaite and Frances McDormand.

The film was released on December 2, 2005 by Paramount Pictures in the United States. The film was panned by critics and was a box office failure, grossing $52.3 million on a production budget of $65 million.

In 2011, a deadly pathogenic virus has killed 99% of the Earth’s population, forcing the survivors to regroup and scatter across the Earth.

404 years later, in late 2415, all of the survivors inhabit Bregna, a walled futuristic city-state, which is ruled by a congress of scientists. Although Bregna is largely an idyllic place in the destroyed Earth, people routinely disappear and the population suffers from nightmares.

Random information on the term “DAY”:

On Earth, daytime is roughly the period on any given point of the planet’s surface during which it experiences natural illumination from indirect or (especially) direct sunlight.

Other planets that rotate in relation to a luminous primary, such as a local star, also experience daytime of a sort, but this article primarily discusses daytime on Earth.

Approximately half of the Earth is illuminated at any time by the Sun. The area subjected to direct illumination is almost exactly half the planet; but because of atmospheric and other effects that extend the reach of indirect illumination, the area of the planet covered by either direct or indirect illumination amounts to slightly more than half the surface.

The hemisphere of the Earth experiencing daytime at any given instant changes continuously as the planet rotates on its own axis. The axis of the Earth’s rotation is not perpendicular to the plane of its orbit around the Sun (which is parallel with the direction of sunlight), and so the length of the daytime period varies from one point on the planet to another. Additionally, since the axis of rotation is relatively fixed in comparison to the stars, it moves with respect to the Sun as the planet orbits the star. This creates seasonal variations in the length of the daytime period at most points on the planet’s surface.

Random information on the term “EPOCH”:

In astronomy, an epoch is a moment in time used as a reference point for some time-varying astronomical quantity, such as the celestial coordinates or elliptical orbital elements of a celestial body, because these are subject to perturbations and vary with time. These time-varying astronomical quantities might include, for example, the mean longitude or mean anomaly of a body, the node of its orbit relative to a reference plane, the direction of the apogee or aphelion of its orbit, or the size of the major axis of its orbit.

The main use of astronomical quantities specified in this way is to calculate other relevant parameters of motion, in order to predict future positions and velocities. The applied tools of the disciplines of celestial mechanics or its subfield orbital mechanics (for predicting orbital paths and positions for bodies in motion under the gravitational effects of other bodies) can be used to generate an ephemeris, a table of values giving the positions and velocities of astronomical objects in the sky at a given time or times.
