Myriad
In the context of numeric naming systems for powers of ten, myriad is the quantity ten thousand ( 10,000). Idiomatically, in English, ''myriad'' is an adjective used to mean that a group of things has indefinitely large quantity. ''Myriad'' derives from the ancient Greek for ten thousand () and is used with this meaning in literal translations from Greek, Latin or Sinospheric languages ( Chinese, Japanese, Korean, and Vietnamese), and in reference to ancient Greek numerals. The term ''myriad'' is also used in the form "a myriad" for a 100 km × 100 km square (10,000 km²) the grid size of the British Ordnance Survey National Grid and the US Military Grid Reference System. It contains 100 hectads. History The Aegean numerals of the Minoan and Mycenaean civilizations included a symbol composed of a circle with four dashes to denote tens of thousands. In classical Greek numerals, myriad was written as a capital mu: Μ. To distinguish this numeral from letters, i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
10,000
10,000 (ten thousand) is the natural number following 9,999 and preceding 10,001. Name Many languages have a specific word for this number: in Ancient Greek it is (the etymological root of the word myriad in English), in Aramaic , in Hebrew [], in Chinese language, Chinese (Mandarin , Cantonese , Hokkien ''bān''), in Japanese language, Japanese [], in Khmer language, Khmer [], in Korean language, Korean [], in Russian language, Russian [], in Vietnamese language, Vietnamese , in Sanskrit अयुत [''ayuta''], in Thai language, Thai [], in Malayalam [], and in Malagasy language, Malagasy ''alina''. In many of these languages, it often denotes a very large but indefinite number. The classical Greeks used letters of the Greek alphabet to represent Greek numerals: they used a capital letter mu (Μ) to represent ten thousand. This Greek root was used in early versions of the metric system in the form of the decimal prefix myria-. Depending on the country, the nu ...

Ordnance Survey National Grid
The Ordnance Survey National Grid reference system (OSGB), also known as British National Grid (BNG), is a system of geographic grid references, distinct from latitude and longitude, whereby any location in Great Britain can be described in terms of its distance from the origin (0, 0), which lies to the west of the Isles of Scilly. The Ordnance Survey (OS) devised the national grid reference system, and it is heavily used in its survey data, and in maps based on those surveys, whether published by the Ordnance Survey or by commercial map producers. Grid references are also commonly quoted in other publications and data sources, such as guide books and government planning documents. A number of different systems exist that can provide grid references for locations within the British Isles: this article describes the system created solely for Great Britain and its outlying islands (including the Isle of Man). The Irish grid reference system is a similar system created by the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hectad (unit Of Area)
A hectad is an area 10 km x 10 km square. The term has a particular use in connection with the British Ordnance Survey national grid, and then refers to any of the 100 such squares which make up a standard 100 km x 100 km myriad; these are denoted using the letter code of the 100 km square, and then a two-digit number consisting of the one-digit easting of the western bound of the hectad and the one-digit northing of its southern bound. See also * Tetrad (unit of area) A tetrad is an area 2 km x 2 km square. The term refers to any of the 25 such squares which make up a standard hectad.

Aegean Numerals
Aegean numbers was an additive Sign-value notation, sign-value numeral system used by the Minoan civilization, Minoan and Mycenaean Greece, Mycenaean civilizations. They are attested in the Linear A and Linear B scripts. They may have survived in the Cypro-Minoan script, where a single sign with "100" value is attested so far on a large clay tablet from Enkomi (archaeological site), Enkomi.

Mycenaean Civilization
Mycenaean Greece (or the Mycenaean civilization) was the last phase of the Bronze Age in ancient Greece, spanning the period from approximately 1750 to 1050 BC.. It represents the first advanced and distinctively Greek civilization in mainland Greece with its palatial states, urban organization, works of art, and writing system.. The Mycenaeans were mainland Greek peoples who were likely stimulated by their contact with insular Minoan Crete and other Mediterranean cultures to develop a more sophisticated sociopolitical culture of their own. The most prominent site was Mycenae, after which the culture of this era is named. Other centers of power that emerged included Pylos, Tiryns, and Midea in the Peloponnese, Orchomenos, Thebes, and Athens in Central Greece, and Iolcos in Thessaly. Mycenaean settlements also appeared in Epirus, Macedonia, on islands in the Aegean Sea, on the south-west coast of Asia Minor, and on Cyprus, while Mycenaean-influenced settlements appeared ...

Mu (letter)
Mu, or my (; uppercase Μ, lowercase μ; Ancient Greek , or μυ—both ), is the twelfth letter of the Greek alphabet, representing the voiced bilabial nasal . In the system of Greek numerals it has a value of 40. Mu was derived from the Egyptian hieroglyphic symbol for water, which had been simplified by the Phoenicians and named after their word for water, to become 𐤌 (mem). Letters that derive from mu include the Roman M and the Cyrillic М, though the lowercase resembles a small Latin U (u). Names Ancient Greek In Greek, the name of the letter was written and pronounced . Modern Greek In Modern Greek, the letter is spelled and pronounced . In polytonic orthography, it is written with an acute accent: . Use as symbol The lowercase letter mu (μ) is used as a special symbol in many academic fields. Uppercase mu is not used, because it appears identical to Latin M. Prefix for units of measurement "μ" is used as a unit prefix denoting a facto ...

Overbar
An overline, overscore, or overbar, is a typographical feature of a horizontal line drawn immediately above the text. In old mathematical notation, an overline was called a '' vinculum'', a notation for grouping symbols which is expressed in modern notation by parentheses, though it persists for symbols under a radical sign. The original use in Ancient Greek was to indicate compositions of Greek letters as Greek numerals. In Latin, it indicates Roman numerals multiplied by a thousand and it forms medieval abbreviations ( sigla). Marking one or more words with a continuous line above the characters is sometimes called '' overstriking'', though overstriking generally refers to printing one character on top of an already-printed character. An overline, that is, a single line above a chunk of text, should not be confused with the macron, a diacritical mark placed above (or sometimes below) ''individual'' letters. The macron is narrower than the character box. Uses Medicine In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Powers Of Ten
In mathematics, a power of 10 is any of the integer powers of the number ten; in other words, ten multiplied by itself a certain number of times (when the power is a positive integer). By definition, the number one is a power (the zeroth power) of ten. The first few non-negative powers of ten are: : 1, 10, 100, 1,000, 10,000, 100,000, 1,000,000, 10,000,000... Positive powers In decimal notation the ''n''th power of ten is written as '1' followed by ''n'' zeroes. It can also be written as 10''n'' or as 1E''n'' in E notation. See order of magnitude and orders of magnitude (numbers) for named powers of ten. There are two conventions for naming positive powers of ten, beginning with 109, called the long and short scales. Where a power of ten has different names in the two conventions, the long scale name is shown in parentheses. The positive 10 power related to a short scale name can be determined based on its Latin name-prefix using the following formula: 10 prefix-number ...

Proto-Indo-European
Proto-Indo-European (PIE) is the reconstructed common ancestor of the Indo-European language family. No direct record of Proto-Indo-European exists; its proposed features have been derived by linguistic reconstruction from documented Indo-European languages. Far more work has gone into reconstructing PIE than any other proto-language, and it is the best understood of all proto-languages of its age. The majority of linguistic work during the 19th century was devoted to the reconstruction of PIE and its daughter languages, and many of the modern techniques of linguistic reconstruction (such as the comparative method) were developed as a result. PIE is hypothesized to have been spoken as a single language from approximately 4500 BCE to 2500 BCE during the Late Neolithic to Early Bronze Age, though estimates vary by more than a thousand years. According to the prevailing Kurgan hypothesis, the proto-Indo-European homeland, original homeland of the Proto-Indo-Europeans may ...

Adjective
An adjective (abbreviations, abbreviated ) is a word that describes or defines a noun or noun phrase. Its semantic role is to change information given by the noun. Traditionally, adjectives are considered one of the main part of speech, parts of speech of the English language, although historically they were classed together with Noun, nouns. Nowadays, certain words that usually had been classified as adjectives, including ''the'', ''this'', ''my'', etc., typically are classed separately, as Determiner (class), determiners. Examples: * That's a ''funny'' idea. (Prepositive attributive) * That idea is ''funny''. (Predicate (grammar), Predicative) * * The ''good'', the ''bad'', and the ''funny''. (Substantive adjective, Substantive) * Clara Oswald, completely ''fictional'', died three times.
