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.

Latin Alphabet Ħħ
Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the Roman Republic it became the dominant language in the Italian region and subsequently throughout the Roman Empire. Even after the fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when other regional vernaculars (including its own descendants, the Romance languages) supplanted it in common academic and political usage, and it eventually became a dead language in the modern linguistic definition. Latin is a highly inflected language, with three distinct genders (masculine, feminine, and neuter), six or seven noun cases (nominative, accusative, genitive, dative, ablative, and vocative), five declensions, four verb conjuga ...

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 ...

List Of XML And HTML Character Entity References
In SGML, HTML and XML documents, the logical constructs known as ''character data'' and ''attribute values'' consist of sequences of characters, in which each character can manifest directly (representing itself), or can be represented by a series of characters called a ''character reference'', of which there are two types: a ''numeric character reference'' and a ''character entity reference''. This article lists the character entity references that are valid in HTML and XML documents. A character entity reference refers to the content of a named entity. An entity declaration is created by using the syntax in a Document Type Definition (DTD). Character reference overview A numeric character reference refers to a character by its Universal Character Set/Unicode ''code point'', and uses the format: :&#''nnnn''; or :&#x''hhhh''; where ''nnnn'' is the code point in decimal form, and ''hhhh'' is the code point in hexadecimal form. The x must be lowercase in XML documents. The ''nnnn'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ISO/IEC 8859-3
ISO/IEC 8859-3:1999, ''Information technology — 8-bit single-byte coded graphic character sets — Part 3: Latin alphabet No. 3'', is part of the ISO/IEC 8859 series of ASCII-based standard character encodings, first edition published in 1988. It is informally referred to as Latin-3 or ''South European''. It was designed to cover Turkish, Maltese and Esperanto, though the introduction of ISO/IEC 8859-9 superseded it for Turkish. The encoding was popular for users of Esperanto, but fell out of use as application support for Unicode became more common. ISO-8859-3 is the IANA preferred charset name for this standard when supplemented with the C0 and C1 control codes from ISO/IEC 6429. Microsoft has assigned code page 28593 a.k.a. Windows-28593 to ISO-8859-3 in Windows. IBM has assigned code page 913 (CCSID 913) to ISO 8859-3.

WGL-4
Windows Glyph List 4, or more commonly WGL4 for short, also known as the ''Pan-European character set'', is a character repertoire on Microsoft operating systems comprising 657 Unicode characters, two of them private use. Its purpose is to provide an implementation guideline for producers of fonts for the representation of European natural languages; fonts that provide glyphs for the entire set of characters can claim WGL4 compliance and thus can expect to be compatible with a wide range of software. , WGL4 characters were the only ones guaranteed to display correctly on Microsoft Windows. More recent versions of Windows display far more glyphs. Because many fonts are designed to fulfill the WGL4 set, this set of characters is likely to work (display as other than replacement glyphs) on many computer systems. For example, all the non-private-use characters in the table below are likely to display properly, compared to the many missing characters that may be seen in other articles ...

Hashgraph
Hashgraph is a distributed ledger technology that has been described as an alternative to blockchains. The hashgraph technology is currently patented, is used by the public ledger Hedera, and there is a grant to implement the patent as a result of the Apache 2.0's Grant of Patent License (provision #3) so long as the implementation conforms to the terms of the Apache license. The native cryptocurrency of the Hedera Hashgraph system is HBAR. Unlike blockchains, hashgraphs do not bundle data into blocks or use miners to validate transactions. Instead, hashgraphs use a "gossip about gossip" protocol where the individual nodes on the network "gossip" about transactions to create directed acyclic graphs that time-sequence transactions. Each "gossip" message contains one or more transactions plus a timestamp, a digital signature, and cryptographic hashes of two earlier events. This makes Hashgraph form an asynchronous Byzantine Fault-Tolerant (aBFT) consensus algorithm. Hashgraph w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heritage Malta
Heritage Malta ( mt, Patrimonju Malta) is the Maltese national agency for museums, conservation practice and cultural heritage. Created by the Cultural Heritage Act, enacted in 2002, the national agency replaced the former Museums Department. Originally Heritage Malta was entrusted with the management of museums, sites and their collections but in 2005, the agency was also charged with the take over of the former Malta Centre for Restoration to become the national agency responsible for conservation. As the national agency responsible for museums, cultural heritage and conservation, Heritage Malta is governed by a Board of Directors appointed by the Minister. The Board is headed by a chairman and is usually appointed for successive three year terms. Logo Until 2022, the logo of Heritage Malta consisted of a white uppercase Ħ on a red square. The H with stroke is a letter found only in the Maltese alphabet. In 2022, Heritage Malta changed its logo to a stylized lowercase "M", w ...

Saturn
Saturn is the sixth planet from the Sun and the second-largest in the Solar System, after Jupiter. It is a gas giant with an average radius of about nine and a half times that of Earth. It has only one-eighth the average density of Earth; however, with its larger volume, Saturn is over 95 times more massive. Saturn's interior is most likely composed of a core of iron–nickel and rock (silicon and oxygen compounds). Its core is surrounded by a deep layer of metallic hydrogen, an intermediate layer of liquid hydrogen and liquid helium, and finally, a gaseous outer layer. Saturn has a pale yellow hue due to ammonia crystals in its upper atmosphere. An electrical current within the metallic hydrogen layer is thought to give rise to Saturn's planetary magnetic field, which is weaker than Earth's, but which has a magnetic moment 580 times that of Earth due to Saturn's larger size. Saturn's magnetic field strength is around one-twentieth of Jupiter's. The outer atmosphere is g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Astronomical Symbols
Astronomical symbols are abstract pictorial symbols used to represent astronomical objects, theoretical constructs and observational events in European astronomy. The earliest forms of these symbols appear in Greek papyrus texts of late antiquity. The Byzantine codices in which many Greek papyrus texts were preserved continued and extended the inventory of astronomical symbols. New symbols have been invented to represent many planets and minor planets discovered in the 18th to the 21st centuries. These symbols were once commonly used by professional astronomers, amateur astronomers, alchemists, and astrologers. While they are still commonly used in almanacs and astrological publications, their occurrence in published research and texts on astronomy is relatively infrequent, with some exceptions such as the Sun and Earth symbols appearing in astronomical constants, and certain zodiacal signs used to represent the solstices and equinoxes. Unicode has encoded many of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tshe
__NOTOC__ Tshe (or Tje) (Ћ ћ; italics: ) is a letter of the Cyrillic script, used only in the Serbian Cyrillic alphabet, where it represents the voiceless alveolo-palatal affricate , somewhat like the pronunciation of in "chew"; however, it must not be confused with the voiceless retroflex affricate Che (Ч ч), which represents and which also exists in Serbian Cyrillic script. The sound of Tshe is produced from the voiceless alveolar plosive by iotation. Tshe is the 23rd letter in the Serbian alphabet. It was first used by Dositej Obradović as a revival of the old Cyrillic letter Djerv (Ꙉ), and was later adopted in the 1818 Serbian dictionary of Vuk Stefanović Karadžić. The equivalent character to Tshe in Gaj's Latin alphabet is Ć. Despite being a Cyrillic letter, Tshe was also used in Latin-based Slovincian phonetic transcriptions with the same value as in Serbian. Being part of the most common Serbian last names, the transliteration of Tshe to the La ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Reduced Planck Constant
The Planck constant, or Planck's constant, is a fundamental physical constant of foundational importance in quantum mechanics. The constant gives the relationship between the energy of a photon and its frequency, and by the mass-energy equivalence, the relationship between mass and frequency. Specifically, a photon's energy is equal to its frequency multiplied by the Planck constant. The constant is generally denoted by h. The reduced Planck constant, or Dirac constant, equal to the constant divided by 2 \pi, is denoted by \hbar. In metrology it is used, together with other constants, to define the kilogram, the SI unit of mass. The SI units are defined in such a way that, when the Planck constant is expressed in SI units, it has the exact value The constant was first postulated by Max Planck in 1900 as part of a solution to the ultraviolet catastrophe. At the end of the 19th century, accurate measurements of the spectrum of black body radiation existed, but the distribut ...
