1829 Braille
Louis Braille's original publication, ''Procedure for Writing Words, Music, and Plainsong in Dots'' (1829), credits Barbier's night writing as being the basis for the braille script. It differed in a fundamental way from modern braille: It contained nine decades (series) of characters rather than the modern five, utilizing dashes as well as dots. Braille recognized, however, that the dashes were problematic, being difficult to distinguish from the dots in practice, and those characters were abandoned in the second edition of the book. The first four decades indicated the 40 letters of the alphabet (39 letters of the French alphabet, plus English ''w''); the fifth the digits; the sixth punctuation; the seventh and part of the eighth mathematical symbols. The seventh decade was also used for musical notes. Most of the remaining characters were unassigned. Script As in modern braille, most of the higher decades were derived from the first: *Decades 1–4 were the same as today and ...

Night Writing
Night writing is the name given to a form of writing invented by Charles Barbier as one of a dozen forms of alternative writing presented in a book published in 1815: ''Essai sur Divers Procédés D'Expéditive Française, Contenant douze écritures différentes, avec une Planche pour chaque procédé'' (Essay on Various Processes of French Expedition, Containing twelve different writings, with a Plate for each process). The term (in French: ''écriture nocturne'') does not appear in the book, but was later applied to the method shown on Plate VII of that book. This method of writing with raised dots that could be read by touch was adopted at the Institution Royale des Jeune Aveugles ( Royal Institution for Blind Youth) in Paris. Barbier also invented the tools for creating writing with raised dots. A student at the school, Louis Braille Louis Braille (; ; 4 January 1809 – 6 January 1852) was a French educator and the inventor of a reading and writing system, named braill ...

Square Root
In mathematics, a square root of a number is a number such that ; in other words, a number whose ''square'' (the result of multiplying the number by itself, or ⋅ ) is . For example, 4 and −4 are square roots of 16, because . Every nonnegative real number has a unique nonnegative square root, called the ''principal square root'', which is denoted by \sqrt, where the symbol \sqrt is called the '' radical sign'' or ''radix''. For example, to express the fact that the principal square root of 9 is 3, we write \sqrt = 3. The term (or number) whose square root is being considered is known as the ''radicand''. The radicand is the number or expression underneath the radical sign, in this case 9. For nonnegative , the principal square root can also be written in exponent notation, as . Every positive number has two square roots: \sqrt, which is positive, and -\sqrt, which is negative. The two roots can be written more concisely using the ± sign as \plusmn\sq ...

Under-ConScript Unicode Registry
The ConScript Unicode Registry is a discontinued volunteer project to coordinate the assignment of code points in the Unicode Private Use Areas (PUA) for the encoding of artificial scripts including those for constructed languages. It was founded by John Cowan and was maintained by him and Michael Everson but has not been updated since 2008 and is no longer actively maintained. It has no formal connection with the Unicode Consortium. Scripts The CSUR includes the following scripts: Font support Some fonts support ConScript Unicode specified code points: * ''Constructium'', a proportional font based on SIL Gentium. * ''Fairfax HD'', a monospaced font intended for text editors and terminals. * ''GNU Unifont'', a bitmap font intended as a fallback font, includes CSUR characters in the separate ''Unifont CSUR'' package. * ''Horta'' * ''Kurinto'' Font Folio See also * Medieval Unicode Font Initiative In digital typography, the Medieval Unicode Font Initiative (MUFI) is a project ...

Unicode Braille Patterns
The Unicode block Braille Patterns (U+2800..U+28FF) contains all 256 possible patterns of an 8-dot braille cell, thereby including the complete 6-dot cell range.Unicode Chapter 15 section 15.10 In Unicode, a braille cell does not have a letter or meaning defined. For example, Unicode does ''not'' define to be "R". Symbols, not letters In Unicode braille characters are not defined as belonging to any other script, but are defined as the Braille script. That is, the patterns are available as ''symbols'', without connection to an alphabetic letter or a number. This is because the ''same'' symbol can be used in multiple scripts, e.g. as a Latin character, a Vietnamese character, a Chinese character and a digit. For example: although represents the letter "H" in basic b ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antoine Notation
French Braille is the original braille alphabet, and the basis of all others. The alphabetic order of French has become the basis of the international braille convention, used by most braille alphabets around the world. However, only the 25 basic letters of the French alphabet plus ''w'' have become internationalized; the additional letters are largely restricted to French Braille and the alphabets of some neighboring European countries. Letters In numerical order by decade, the letters are: For the purposes of accommodating a foreign alphabet, the letters ''ì, ä, ò'' may be added: There are also numerous contractions and abbreviations in French braille. Punctuation Punctuation is as follows: The lower values are readings within numbers (after the Antoine number marker: see below). Formatting and mode Formatting and mode-changing marks are: As in English Braille, the capital sign is doubled for all caps. and are used to begin and end emphasis within a word. T ...

Voiced Consonant
Voice or voicing is a term used in phonetics and phonology to characterize speech sounds (usually consonants). Speech sounds can be described as either voiceless (otherwise known as ''unvoiced'') or voiced. The term, however, is used to refer to two separate concepts: *Voicing can refer to the ''articulatory process'' in which the vocal folds vibrate, its primary use in phonetics to describe phones, which are particular speech sounds. *It can also refer to a classification of speech sounds that tend to be associated with vocal cord vibration but may not actually be voiced at the articulatory level. That is the term's primary use in phonology: to describe phonemes; while in phonetics its primary use is to describe phones. For example, voicing accounts for the difference between the pair of sounds associated with the English letters "s" and "z". The two sounds are transcribed as and to distinguish them from the English letters, which have several possible pronunciations, de ...

Shorthand
Shorthand is an abbreviated symbolic writing method that increases speed and brevity of writing as compared to longhand, a more common method of writing a language. The process of writing in shorthand is called stenography, from the Greek ''stenos'' (narrow) and ''graphein'' (to write). It has also been called brachygraphy, from Greek ''brachys'' (short), and tachygraphy, from Greek ''tachys'' (swift, speedy), depending on whether compression or speed of writing is the goal. Many forms of shorthand exist. A typical shorthand system provides symbols or abbreviations for words and common phrases, which can allow someone well-trained in the system to write as quickly as people speak. Abbreviation methods are alphabet-based and use different abbreviating approaches. Many journalists use shorthand writing to quickly take notes at press conferences or other similar scenarios. In the computerized world, several autocomplete programs, standalone or integrated in text editors, based on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clef
A clef (from French: 'key') is a musical symbol used to indicate which notes are represented by the lines and spaces on a musical stave. Placing a clef on a stave assigns a particular pitch to one of the five lines, which defines the pitches on the remaining lines and spaces. The three clef symbols used in modern music notation are the G-clef, F-clef, and C-clef. Placing these clefs on a line fixes a reference note to that line—an F-clef fixes the F below middle C, a C-clef fixes middle C, and a G-clef fixes the G above middle C. In modern music notation, the G-clef is most frequently seen as treble clef (placing G4 on the second line of the stave), and the F-clef as bass clef (placing F3 on the fourth line). The C-clef is mostly encountered as alto clef (placing middle C on the third line) or tenor clef (middle C on the fourth line). A clef may be placed on a space instead of a line, but this is rare. The use of different clefs makes it possible to write music for a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
