Turned A
Turned A (capital: Ɐ, lowercase: ɐ, math symbol ∀) is a letter and symbol based upon the letter A. Modern usage * Lowercase ɐ (in Roman, or "two-storey" form) is used in the International Phonetic Alphabet to identify the near-open central vowel. This is not to be confused with the ''turned alpha'' or ''turned script a'', ɒ, which is used in the IPA for the open back rounded vowel. * The logical symbol ∀ has the same shape as a sans-serif capital turned A. It is used to represent universal quantification in predicate logic, where it is typically read as "for all". It was first used in this way by Gerhard Gentzen in 1935, by analogy with Giuseppe Peano's turned E notation for existential quantification and the later use of Peano's notation by Bertrand Russell.

Latin Letter Turned A
Latin ( or ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally spoken by the Latins in Latium (now known as Lazio), the lower Tiber area around Rome, Italy. Through the expansion of the Roman Republic, it became the dominant language in the Italian Peninsula and subsequently throughout the Roman Empire. It has greatly influenced many languages, including English, having contributed many words to the English lexicon, particularly after the Christianization of the Anglo-Saxons and the Norman Conquest. Latin roots appear frequently in the technical vocabulary used by fields such as theology, the sciences, medicine, and law. By the late Roman Republic, Old Latin had evolved into standardized Classical Latin. Vulgar Latin refers to the less prestigious colloquial registers, attested in inscriptions and some literary works such as those of the comic playwrights Plautus and Terence and the author Petronius.

Logogram
In a written language, a logogram (from Ancient Greek 'word', and 'that which is drawn or written'), also logograph or lexigraph, is a written character that represents a semantic component of a language, such as a word or morpheme. Chinese characters as used in Chinese as well as other languages are logograms, as are Egyptian hieroglyphs and characters in cuneiform script. A writing system that primarily uses logograms is called a ''logography''. Non-logographic writing systems, such as alphabets and syllabaries, are ''phonemic'': their individual symbols represent sounds directly and lack any inherent meaning. However, all known logographies have some phonetic component, generally based on the rebus principle, and the addition of a phonetic component to pure ideographs is considered to be a key innovation in enabling the writing system to adequately encode human language. Types of logographic systems Some of the earliest recorded writing systems are logographic; th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Symbol (typeface)
Symbol (which would appear as Σψμβολ if the name of the font is written in the font itself) is one of the four standard fonts available on all PostScript-based printers, starting with Apple's original LaserWriter (1985). It contains a complete unaccented Greek alphabet (upper and lower case) and a selection of commonly used mathematical symbols. Insofar as it fits into any standard classification, it is a serif font designed in the style of Times New Roman. Due to its non-standard character set, lack of diacritical characters, and type design inappropriate for continuous text, Symbol cannot easily be used for setting Greek language text, though it has been used for that purpose in the absence of proper Greek fonts. Its primary purpose is to typeset mathematical expressions. There was also an earlier ''Symbol'' designed in 1933 by Carl Albert Fahrenwaldt for Schriftguss Type Foundry. It was a font of decorative initials based on his roman font '' Minister''. Encoding Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uralic Language
The Uralic languages ( ), sometimes called the Uralian languages ( ), are spoken predominantly in Europe and North Asia. The Uralic languages with the most native speakers are Hungarian, Finnish, and Estonian. Other languages with speakers above 100,000 are Erzya, Moksha, Mari, Udmurt and Komi spoken in the European parts of the Russian Federation. Still smaller minority languages are Sámi languages of the northern Fennoscandia; other members of the Finnic languages, ranging from Livonian in northern Latvia to Karelian in northwesternmost Russia; the Samoyedic languages and the others of members of the Ugric languages, Mansi and Khanty spoken in Western Siberia. The name ''Uralic'' derives from the family's purported "original homeland" (''Urheimat'') hypothesized to have been somewhere in the vicinity of the Ural Mountains, and was first proposed by Julius Klaproth in ''Asia Polyglotta'' (1823). Finno-Ugric is sometimes used as a synonym for Uralic but more accu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uralic Phonetic Alphabet
Finno-Ugric transcription (FUT) or the Uralic Phonetic Alphabet (UPA) is a phonetic transcription or notational system used predominantly for the transcription and reconstruction of Uralic languages. It was first published in 1901 by Eemil Nestor Setälä, a Finnish linguist; it was somewhat modified in the 1970s.Sovijärvi & Peltola (1970). A few obvious expansions have been made, such as voiceless ' to pair with voiced '. FUT differs from the International Phonetic Alphabet (IPA) notation in several ways, notably in exploiting italics or boldface rather than using brackets to delimit text, in the use of small capitals for devoicing, and in more frequent use of diacritics to differentiate places of articulation. The basic FUT characters are based on the Finnish alphabet where possible, with extensions taken from Cyrillic and Greek orthographies. Small-capital letters and some novel diacritics are also used. Unlike the IPA, which is usually transcribed in Roman typeface, FU ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Charles Sanders Peirce
Charles Sanders Peirce ( ; September 10, 1839 – April 19, 1914) was an American scientist, mathematician, logician, and philosopher who is sometimes known as "the father of pragmatism". According to philosopher Paul Weiss (philosopher), Paul Weiss, Peirce was "the most original and versatile of America's philosophers and America's greatest logician". Bertrand Russell wrote "he was one of the most original minds of the later nineteenth century and certainly the greatest American thinker ever". Educated as a chemist and employed as a scientist for thirty years, Peirce meanwhile made major contributions to logic, such as theories of Algebraic logic, relations and Quantifier (logic), quantification. Clarence Irving Lewis, C. I. Lewis wrote, "The contributions of C. S. Peirce to symbolic logic are more numerous and varied than those of any other writer—at least in the nineteenth century." For Peirce, logic also encompassed much of what is now called epistemology and the philoso ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cornish Language
Cornish (Standard Written Form: or , ) is a Southwestern Brittonic language, Southwestern Brittonic language of the Celtic language family. Along with Welsh language, Welsh and Breton language, Breton, Cornish descends from Common Brittonic, a language once spoken widely across Great Britain. For much of the Middle Ages, medieval period Cornish was the main language of Cornwall, until it was gradually pushed westwards by the spread of English language, English. Cornish remained a vernacular, common community language in parts of Cornwall until the mid-18th century, and there is some evidence for traditional speakers persisting into the 19th century. Cornish became extinct language, extinct as a living community language in Cornwall by the last speaker of the Cornish language, end of the 18th century, although knowledge of Cornish, including speaking ability to a certain extent, persisted within some families and individuals.

William Pryce
William Pryce (baptised 1735–1790) was a British medical man, known as an antiquary, a promoter of the Cornish language and a writer on mining in Cornwall. Life He was the son of Dr. Samuel Pryce of Redruth in Cornwall, and Catherine Hill; William Borlase was a great-uncle on his mother's side. Philip Webber of Falmouth acted as his guardian when he was left an orphan. He claimed to have studied anatomy under John Hunter, and from about 1750 he practised as a surgeon and apothecary at Redruth. Pryce owned a small share in the copper mine of Dolcoath in Cornwall. For ten years he was also an investor in the adjoining mine of Pednandrea, which was worked for both tin and copper. It was near the future site of the Redruth railway station. Soon after 1778 Pryce "became M.D. by diploma" and on 26 June 1783 he was elected Fellow of the Society of Antiquaries of London. He was buried at Redruth on 20 December 1790.
