Esperanto Orthography
Esperanto is written in a Latin-script alphabet of twenty-eight letters, with upper and lower case. This is supplemented by punctuation marks and by various logograms, such as the digits 0–9, currency signs such as $ € ¥ £ ₷, and mathematical symbols. The creator of Esperanto, L. L. Zamenhof, declared a principle of "one letter, one sound", though this is a general rather than strict guideline.Kalocsay & Waringhien, ''Plena analiza gramatiko'', § 17 Twenty-two of the letters are identical in form to letters of the English alphabet (''q, w, x,'' and ''y'' being omitted). The remaining six have diacritical marks: '' ĉ, ĝ, ĥ, ĵ, ŝ,'' and '' ŭ'' – that is, ''c, g, h, j,'' and ''s circumflex,'' and ''u breve.'' Latin alphabet Standard Esperanto orthography uses the Latin script. Sound values The letters have approximately the sound values of the IPA, with the exception of ''c'' and the letters with diacritics: '' ĉ'' , ''ĝ'' , ''ĥ'' , ''ĵ'' , ''ŝ ...

Esperanto Letters With Diacritics
Esperanto ( or ) is the world's most widely spoken constructed international auxiliary language. Created by the Warsaw-based ophthalmologist L. L. Zamenhof in 1887, it was intended to be a universal second language for international communication, or "the international language" (). Zamenhof first described the language in '' Dr. Esperanto's International Language'' (), which he published under the pseudonym . Early adopters of the language liked the name ''Esperanto'' and soon used it to describe his language. The word translates into English as "one who hopes". Within the range of constructed languages, Esperanto occupies a middle ground between "naturalistic" (imitating existing natural languages) and ''a'priori'' (where features are not based on existing languages). Esperanto's vocabulary, syntax and semantics derive predominantly from languages of the Indo-European group. The vocabulary derives primarily from Romance languages, with substantial contributions from G ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Circumflex
The circumflex () is a diacritic in the Latin and Greek scripts that is also used in the written forms of many languages and in various romanization and transcription schemes. It received its English name from la, circumflexus "bent around"a translation of the el, περισπωμένη (). The circumflex in the Latin script is chevron-shaped (), while the Greek circumflex may be displayed either like a tilde () or like an inverted breve (). For the most commonly encountered uses of the accent in the Latin alphabet, precomposed characters are available. In English, the circumflex, like other diacritics, is sometimes retained on loanwords that used it in the original language (for example, ''crème brûlée''). In mathematics and statistics, the circumflex diacritic is sometimes used to denote a function and is called a ''hat operator''. A free-standing version of the circumflex symbol, , has become known as ''caret'' and has acquired special uses, particularly in computing ...

Esperanto Vocabulary
The original word base of Esperanto contained around 900 root words and was defined in ''Unua Libro'' ("First Book"), published by L. L. Zamenhof in 1887. In 1894, Zamenhof published the first Esperanto dictionary, '' Universala vortaro'' ("International Dictionary"), which was written in five languages and supplied a larger set of root words, adding 1740 new words. The rules of the Esperanto language allow speakers to borrow words as needed, recommending only that they look for the most international words, and that they borrow one basic word and derive others from it, rather than borrowing many words with related meanings. Since then, many words have been borrowed from other languages, primarily those of Western Europe. In recent decades, most of the new borrowings or coinages have been technical or scientific terms; terms in everyday use are more likely to be derived from existing words (for example computer from o compute, or extending them to cover new meanin ...

International Auxiliary Language
An international auxiliary language (sometimes acronymized as IAL or contracted as auxlang) is a language meant for communication between people from all different nations, who do not share a common first language. An auxiliary language is primarily a foreign language and often a constructed language. The concept is related to but separate from the idea of a '' lingua franca'' (or dominant language) that people must use to communicate. The term "auxiliary" implies that it is intended to be an additional language for communication between the people of the world, rather than to replace their native languages. Often, the term is used specifically to refer to planned or constructed languages proposed to ease international communication, such as Esperanto, Ido and Interlingua. It usually takes words from widely spoken languages. However, it can also refer to the concept of such a language being determined by international consensus, including even a standardized natural language (e.g., ...

Voiceless Velar Fricative
The voiceless velar fricative is a type of consonantal sound used in some spoken languages. It was part of the consonant inventory of Old English and can still be found in some dialects of English, most notably in Scottish English, e.g. in ''loch'', ''broch'' or ''saugh'' (willow). The symbol in the International Phonetic Alphabet that represents this sound is , the Latin letter x. It is also used in broad transcription instead of the symbol , the Greek chi, for the voiceless uvular fricative. There is also a voiceless post-velar fricative (also called pre-uvular) in some languages, which can be transcribed as ̠or ̟ For voiceless pre-velar fricative (also called post-palatal), see voiceless palatal fricative. Features Features of the voiceless velar fricative: Varieties Occurrence The voiceless velar fricative and its labialized variety are postulated to have occurred in Proto-Germanic, the ancestor of the Germanic languages, as the reflex of the Proto-Ind ...

Wheeler–DeWitt Equation
The Wheeler–DeWitt equation for theoretical physics and applied mathematics, is a field equation attributed to John Archibald Wheeler and Bryce DeWitt. The equation attempts to mathematically combine the ideas of quantum mechanics and general relativity, a step towards a theory of quantum gravity. In this approach, time plays a role different from what it does in non-relativistic quantum mechanics, leading to the so-called 'problem of time'. More specifically, the equation describes the quantum version of the Hamiltonian constraint using metric variables. Its commutation relations with the diffeomorphism constraints generate the Bergman–Komar "group" (which ''is'' the diffeomorphism group on-shell). Quantum gravity All defined and understood descriptions of string/M-theory deal with fixed asymptotic conditions on the background spacetime. At infinity, the "right" choice of the time coordinate "t" is determined (because the space-time is asymptotic to some fixed space-time) ...

H With Stroke
Ħ (minuscule: ħ) is a letter of the Latin alphabet, derived from H with the addition of a bar. It is used in Maltese for a voiceless pharyngeal fricative consonant (corresponding to the letter ''heth'' of Semitic abjads: ar, ح, he, ח). Lowercase is used in the International Phonetic Alphabet for the same sound. In Unicode, the special character ℏ (U+210F), represents the reduced Planck constant of quantum mechanics. In this context, it is pronounced "h-bar". The lowercase resembles the Cyrillic letter Tshe (ћ), or the astronomical symbol of Saturn (♄). A white uppercase Ħ on a red square was the logo of Heritage Malta until 2022. It is used as the symbol for Hedera Hashgraph's native cryptocurrency, HBAR.

Quantum Mechanics
Quantum mechanics is a fundamental theory in physics that provides a description of the physical properties of nature at the scale of atoms and subatomic particles. It is the foundation of all quantum physics including quantum chemistry, quantum field theory, quantum technology, and quantum information science. Classical physics, the collection of theories that existed before the advent of quantum mechanics, describes many aspects of nature at an ordinary (macroscopic) scale, but is not sufficient for describing them at small (atomic and subatomic) scales. Most theories in classical physics can be derived from quantum mechanics as an approximation valid at large (macroscopic) scale. Quantum mechanics differs from classical physics in that energy, momentum, angular momentum, and other quantities of a bound system are restricted to discrete values ( quantization); objects have characteristics of both particles and waves (wave–particle duality); and there are limits to ...

Chi (letter)
Chi (uppercase Χ, lowercase χ; el, χῖ) is the 22nd letter of the Greek alphabet. Greek Pronunciation Ancient Greek Its value in Ancient Greek was an aspirated velar stop (in the Western Greek alphabet: /ks/). Koine Greek In Koine Greek and later dialects it became a fricative (/) along with Θ and Φ. Modern Greek In Modern Greek, it has two distinct pronunciations: In front of high or front vowels ( or ) it is pronounced as a voiceless palatal fricative , as in German ''ich'' or like the ''h'' in some pronunciations of the English words ''hew'' and ''human''. In front of low or back vowels (, or ) and consonants, it is pronounced as a voiceless velar fricative (), as in German ''ach'' or Spanish ''j''. Transliteration Chi is romanized as in most systematic transliteration conventions, but sometimes is used. In addition, in Modern Greek, it is often also romanized as or in informal practice. Greek numeral In the system of Greek numerals, it has a value of 6 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
