Undecimal
The undecimal numeral system (also known as the base-11 numeral system) is a Positional notation, positional numeral system that uses 11 (number), eleven as its Radix, base. While no known society counts by elevens, two are purported to have done so: the Māori people, Māori, one of the two Polynesians, Polynesian peoples of New Zealand, and the Pañgwa (Pangwa), a Bantu languages, Bantu-speaking people of Tanzania. The idea of counting by elevens remains of interest for its relation to a traditional method of tally-counting practiced in Polynesia. During the French Revolution, base-11 was briefly mentioned as a possible basis for the reformed system of measurement. Base-11 numerals also appear in the International Standard Book Number system. Alleged use of base-11 in cultural number systems Use by the Māori Conant and Williams For about a century, the idea that Māori counted by elevens was best known from its mention in the writing of the American mathematician Levi Leonard ...

Mangareva
Mangareva is the central and largest island of the Gambier Islands in French Polynesia. It is surrounded by smaller islands: Taravai in the southwest, Aukena and Akamaru in the southeast, and islands in the north. Mangareva has a permanent population of 1,239 (2012) and the largest village on the island, Rikitea, is the chief town of the Gambier Islands. The island is approximately long and, at , it comprises about 56% of the land area of the whole Gambier group. Mangareva has a high central ridge which runs the length of the island. The highest point in the Gambiers is Mount Duff, on Mangareva, rising to along the island's south coast. The island has a large lagoon in diameter containing reefs whose fish and shellfish helped ancient islanders survive much more successfully than on nearby islands with no reefs. History Mangareva was first settled by Polynesians in the first millennium CE. While carbon dating has so far only dated settlements to 1160-1220, there is evidence ...

Numeral System
A numeral system (or system of numeration) is a writing system for expressing numbers; that is, a mathematical notation for representing numbers of a given set, using Numerical digit, digits or other symbols in a consistent manner. The same sequence of symbols may represent different numbers in different numeral systems. For example, "11" represents the number ''eleven'' in the decimal numeral system (used in common life), the number ''three'' in the binary numeral system (used in computers), and the number ''two'' in the unary numeral system (e.g. used in Tally marks, tallying scores). The number the numeral represents is called its value. Not all number systems can represent all numbers that are considered in the modern days; for example, Roman numerals have no zero. Ideally, a numeral system will: *Represent a useful set of numbers (e.g. all integers, or rational numbers) *Give every number represented a unique representation (or at least a standard representation) *Reflec ...

French Ship Astrolabe (1811)
''Astrolabe'' was originally a horse-transport barge converted into an exploration ship of the French Navy. Originally named ''Coquille'', she is famous for her travels with Jules Dumont d'Urville.

Career Voyage under the command of Louis Isidore Duperrey Louis-Isidore Duperrey commanded ''Coquille'' on its circumnavigation of the earth (1822–1825) with Jules Dumont d'Urville as second.

During the voyage the ship spent two weeks in the Bay of Islands in the north of New Zealand in 1824. The vessel arrived in Kosrae where Duperrey ...

Samuel Lee (linguist)
Samuel Lee (14 May 1783 – 16 December 1852) was an English Orientalist, born in Shropshire; professor at Cambridge, first of Arabic and then of Hebrew language; was the author of a Hebrew grammar and lexicon, and a translation of the '' Book of Job''. Biography Born of poor parents at Longnor, a Shropshire village 8 miles from Shrewsbury, Samuel Lee received a charity school education and at age twelve became a carpenter's apprentice in Shrewsbury. He was fond of reading and acquired knowledge of a number of languages. An early marriage caused him to reduce the time devoted to his studies, but the accidental loss of his tools caused him to become a school teacher, giving private lessons in Persian and Hindustani. His remarkable linguistic abilities eventually brought him to the notice of the Church Missionary Society, which paid for his education at Cambridge University. He entered Queens' College, Cambridge, in 1813. He graduated B.A. in 1818, and proceeded M.A. in 1819, ...

Vigesimal
vigesimal () or base-20 (base-score) numeral system is based on twenty (in the same way in which the decimal numeral system is based on ten). '' Vigesimal'' is derived from the Latin adjective '' vicesimus'', meaning 'twentieth'. Places In a vigesimal place system, twenty individual numerals (or digit symbols) are used, ten more than in the usual decimal system. One modern method of finding the extra needed symbols is to write ten as the letter (the 20 means base ), to write nineteen as , and the numbers between with the corresponding letters of the alphabet. This is similar to the common computer-science practice of writing hexadecimal numerals over 9 with the letters "A–F". Another less common method skips over the letter "I", in order to avoid confusion between I20 as eighteen and one, so that the number eighteen is written as J20, and nineteen is written as K20. The number twenty is written as . According to this notation: : is equivalent to forty in decimal ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
