Armenians
Armenians ( hy, հայեր, ''hayer'' ) are an ethnic group native to the Armenian highlands of Western Asia. Armenians constitute the main population of Armenia and the ''de facto'' independent Artsakh. There is a wide-ranging diaspora of around five million people of full or partial Armenian ancestry living outside modern Armenia. The largest Armenian populations today exist in Russia, the United States, France, Georgia, Iran, Germany, Ukraine, Lebanon, Brazil, and Syria. With the exceptions of Iran and the former Soviet states, the present-day Armenian diaspora was formed mainly as a result of the Armenian genocide. Richard G. Hovannisian, ''The Armenian people from ancient to modern times: the fifteenth century to the twentieth century'', Volume 2, p. 421, Palgrave Macmillan, 1997. Armenian is an Indo-European language. It has two mutually intelligible spoken and written forms: Eastern Armenian, today spoken mainly in Armenia, Artsakh, Iran, and the former Soviet ...

Catholicos Of All Armenians
The Catholicos of All Armenians (plural Catholicoi) ( hy, Ամենայն Հայոց Կաթողիկոս; see #Other names), is the chief bishop and spiritual leader of Armenia's national church, the Armenian Apostolic Church, and the worldwide Armenian diaspora. According to tradition, the apostles Saint Thaddeus and Saint Bartholomew brought Christianity to Armenia in the first century. Saint Gregory the Illuminator became the first Catholicos of All Armenians following the nation's adoption of Christianity as its official religion in 301 AD. The seat of the Catholicos, and the spiritual and administrative headquarters of the Armenian Church, is the Mother See of Holy Etchmiadzin, located in the city of Vagharshapat. The Armenian Apostolic Church is part of the Oriental Orthodox communion. This communion includes the Coptic Orthodox Church of Alexandria, the Ethiopian Orthodox Tewahedo Church, the Syriac Orthodox Church, the Malankara Orthodox Syrian Church, and the Eritrean Ort ...

Carahunge
Carahunge ( hy, Քարահունջ, also romanized as Karahunj and Qarahunj), also known as Zorats Karer (), Dik-Dik Karer (), Tsits Karer () and Karenish ( hy, Քարենիշ), is a prehistoric archaeological site near the town of Sisian in the Syunik Province of Armenia. It is also often referred to in international tourist lore as the "Armenian Stonehenge". Location The Carahunge site is at latitude 39° 34' longitude 46° 01' on a mountain plateau at an altitude of and occupies an area of about 7 hectares on the left side of the canyon of the River Dar, a tributary of the river Vorotan (at 2 km). It is located on a rocky promontory near Sisian.

Megalith
A megalith is a large stone that has been used to construct a prehistoric structure or monument, either alone or together with other stones. There are over 35,000 in Europe alone, located widely from Sweden to the Mediterranean sea. The word was first used in 1849 by the British antiquarian Algernon Herbert in reference to Stonehenge and derives from the Ancient Greek words "mega" for great and " lithos" for stone. Most extant megaliths were erected between the Neolithic period (although earlier Mesolithic examples are known) through the Chalcolithic period and into the Bronze Age. At that time, the beliefs that developed were dynamism and animism, because Indonesia experienced the megalithic age or the great stone age in 2100 to 4000 BC. So that humans ancient tribe worship certain objects that are considered to have supernatural powers. Some relics of the megalithic era are menhirs (stone monuments) and dolmens (stone tables).

Red Giant
A red giant is a luminous giant star of low or intermediate mass (roughly 0.3–8 solar masses ()) in a late phase of stellar evolution. The outer atmosphere is inflated and tenuous, making the radius large and the surface temperature around or lower. The appearance of the red giant is from yellow-white to reddish-orange, including the spectral types K and M, sometimes G, but also class S stars and most carbon stars. Red giants vary in the way by which they generate energy: * most common red giants are stars on the red-giant branch (RGB) that are still fusing hydrogen into helium in a shell surrounding an inert helium core * red-clump stars in the cool half of the horizontal branch, fusing helium into carbon in their cores via the triple-alpha process * asymptotic-giant-branch (AGB) stars with a helium burning shell outside a degenerate carbon–oxygen core, and a hydrogen-burning shell just beyond that. Many of the well-known bright stars are red giants because they are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eta Geminorum
Eta Geminorum (η Geminorum, abbreviated Eta Gem, η Gem), formally named Propus , is a triple star system in the constellation of Gemini. It is a naked-eye variable star around 380 light years from the Sun. Nomenclature ''Eta Geminorum'' is the star's Bayer designation. The traditional names ''Tejat Prior'', ''Propus'' (from the Greek, meaning forward foot) and ''Praepes'' and ''Pish Pai'' (from the Persian Pīshpāy, پیشپای, meaning foreleg). In 2016, the International Astronomical Union organized a Working Group on Star Names (WGSN) to catalog and standardize proper names for stars. The WGSN's first bulletin of July 2016 included a table of the first two batches of names approved by the WGSN; which included ''Propus'' for this star. This star, along with γ Gem (Alhena), μ Gem (Tejat Posterior), ν Gem and ξ Gem (Alzirr) were ''Al Han'ah'', "the brand" (on the neck of the camel). They also were associated in ''Al Nuḥātai'', the dual form of ''Al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metrology
Metrology is the scientific study of measurement. It establishes a common understanding of units, crucial in linking human activities. Modern metrology has its roots in the French Revolution's political motivation to standardise units in France when a length standard taken from a natural source was proposed. This led to the creation of the decimal-based metric system in 1795, establishing a set of standards for other types of measurements. Several other countries adopted the metric system between 1795 and 1875; to ensure conformity between the countries, the Bureau International des Poids et Mesures (BIPM) was established by the Metre Convention. This has evolved into the International System of Units (SI) as a result of a resolution at the 11th General Conference on Weights and Measures (CGPM) in 1960. Metrology is divided into three basic overlapping activities: * The definition of units of measurement * The realisation of these units of measurement in practice * Traceabi ...

Aperture
In optics, an aperture is a hole or an opening through which light travels. More specifically, the aperture and focal length of an optical system determine the cone angle of a bundle of rays that come to a focus in the image plane. An optical system typically has many openings or structures that limit the ray bundles (ray bundles are also known as ''pencils'' of light). These structures may be the edge of a lens or mirror, or a ring or other fixture that holds an optical element in place, or may be a special element such as a diaphragm placed in the optical path to limit the light admitted by the system. In general, these structures are called stops, and the aperture stop is the stop that primarily determines the ray cone angle and brightness at the image point. In some contexts, especially in photography and astronomy, ''aperture'' refers to the diameter of the aperture stop rather than the physical stop or the opening itself. For example, in a telescope, the aperture ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monographs
A monograph is a specialist work of writing (in contrast to reference works) or exhibition on a single subject or an aspect of a subject, often by a single author or artist, and usually on a scholarly subject. In library cataloging, ''monograph'' has a broader meaning—that of a nonserial publication complete in one volume (book) or a definite number of volumes. Thus it differs from a serial or periodical publication such as a magazine, academic journal, or newspaper. In this context only, books such as novels are considered monographs.__FORCETOC__ Academia The English term "monograph" is derived from modern Latin "monographia", which has its root in Greek. In the English word, "mono-" means "single" and "-graph" means "something written". Unlike a textbook, which surveys the state of knowledge in a field, the main purpose of a monograph is to present primary research and original scholarship ascertaining reliable credibility to the required recipient. This research is prese ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Russian Academy Of Sciences
The Russian Academy of Sciences (RAS; russian: Росси́йская акаде́мия нау́к (РАН) ''Rossíyskaya akadémiya naúk'') consists of the national academy of Russia; a network of scientific research institutes from across the Russian Federation; and additional scientific and social units such as libraries, publishing units, and hospitals. Peter the Great established the Academy (then the St. Petersburg Academy of Sciences) in 1724 with guidance from Gottfried Leibniz. From its establishment, the Academy benefitted from a slate of foreign scholars as professors; the Academy then gained its first clear set of goals from the 1747 Charter. The Academy functioned as a university and research center throughout the mid-18th century until the university was dissolved, leaving research as the main pillar of the institution. The rest of the 18th century continuing on through the 19th century consisted of many published academic works from Academy scholars and a few Ac ...
