β Cephei Variable
Beta (, ; uppercase , lowercase , or cursive ; or ) is the second letter of the Greek alphabet. In the system of Greek numerals, it has a value of 2. In Ancient Greek, beta represented the voiced bilabial plosive . In Modern Greek, it represents the voiced bilabial fricative while in borrowed words is instead commonly transcribed as μπ. Letters that arose from beta include the Roman letter and the Cyrillic letters and . Name Like the names of most other Greek letters, the name of beta was adopted from the acrophonic name of the corresponding letter in Phoenician, which was the common Semitic word ('house', compare and ). In Greek, the name was , pronounced in Ancient Greek. It is spelled in modern monotonic orthography and pronounced . History The letter beta was derived from the Phoenician letter beth . The letter Β had the largest number of highly divergent local forms. Besides the standard form (either rounded or pointed, ), there were forms as varied ...

Cursive Greek
Cursive (also known as joined-up writing) is any style of penmanship in which characters are written joined in a flowing manner, generally for the purpose of making writing faster, in contrast to block letters. It varies in functionality and modern-day usage across languages and regions; being used both publicly in artistic and formal documents as well as in private communication. Formal cursive is generally joined, but casual cursive is a combination of joins and pen lifts. The writing style can be further divided as "looped", "italic script, italic", or "connected". The cursive method is used with many alphabets due to infrequent pen lifting which allows increased writing speed. However, more elaborate or ornamental calligraphic styles of writing can be slower to reproduce. In some alphabets, many or all letters in a word are connected, sometimes making a word one single complex stroke. History Cursive is a style of penmanship in which the symbols of the language are writt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Melos
Milos or Melos (; , ; ) is a volcanic Greek island in the Aegean Sea, just north of the Sea of Crete. It is the southwestern-most island of the Cyclades group. The ''Venus de Milo'' (now in the Louvre), the '' Poseidon of Melos'' (now in the NAMA) and the '' Asclepius of Milos'' (now in the British Museum) were all found on the island, as was an archaic Apollo now in Athens. Milos is a popular tourist destination during the summer. The municipality of Milos also includes the uninhabited offshore islands of Antimilos and Akradies. The combined land area is and at the 2021 census the population was 5,193 inhabitants. History Obsidian (a glass-like volcanic rock) from Milos was a commodity as early as 15,000 years ago. Natural glass from Milos was transported over long distances and used for razor-sharp "stone tools" well before farming began and later: "There is no early farming village in the Near East that doesn't get obsidian". The mining of obsidian did not lead to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2005 Atlantic Hurricane Season
The 2005 Atlantic hurricane season was a record-breaking, devastating and deadly Atlantic hurricane season. It is the second-costliest hurricane season, just behind the 2017 season And 2024. It featured 28 tropical and subtropical storms, which was the most recorded in a hurricane season until the 2020 season. The United States National Hurricane Center named 27 storms, exhausting the annual pre-designated list, requiring the use of six Greek letter names, and adding an additional unnamed subtropical storm during a post-season re-analysis. A record 15 storms attained hurricane status, with maximum sustained winds of at least . Of those, a record seven became major hurricanes, rated Category 3 or higher on the Saffir–Simpson scale. Four storms of this season became Category 5 hurricanes, the most of any season on record. The four Category 5 hurricanes during the season were: Emily, Katrina, Rita, and Wilma. In July, Emily reached peak i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hurricane Beta
Hurricane Beta was a compact and intense tropical cyclone that impacted the southwestern Caribbean in late October 2005. Beta was the twenty-fourth tropical storm, fourteenth hurricane, and seventh and final Category 3 hurricane, major hurricane of the record-breaking 2005 Atlantic hurricane season. On October 21, a developing tropical wave entered the eastern Caribbean Sea and spawned Tropical Storm Alpha (2005), Tropical Storm Alpha the following day. As the wave entered the southwestern Caribbean, convection redeveloped and on October 26, the system spawned another low-pressure area which developed into Tropical Depression Twenty-six. The depression intensified into a tropical storm the next morning and was named Beta. By the morning of October 28, the storm intensified into a hurricane, the fourteenth of the season. Beta underwent rapid deepening, rapid intensification for several hours to attain its peak intensity with winds of on October 30. The st ...

Tropical Cyclone
A tropical cyclone is a rapidly rotating storm system with a low-pressure area, a closed low-level atmospheric circulation, strong winds, and a spiral arrangement of thunderstorms that produce heavy rain and squalls. Depending on its location and strength, a tropical cyclone is called a hurricane (), typhoon (), tropical storm, cyclonic storm, tropical depression, or simply cyclone. A hurricane is a strong tropical cyclone that occurs in the Atlantic Ocean or northeastern Pacific Ocean. A typhoon is the same thing which occurs in the northwestern Pacific Ocean. In the Indian Ocean and South Pacific, comparable storms are referred to as "tropical cyclones". In modern times, on average around 80 to 90 named tropical cyclones form each year around the world, over half of which develop hurricane-force winds of or more. Tropical cyclones tropical cyclogenesis, typically form over large bodies of relatively warm water. They derive their energy through the evaporation of water ...

Tropical Cyclone Naming
Tropical cyclones and subtropical cyclones are named by various warning centers to simplify communication between forecasters and the general public regarding forecasts, watches and warnings. The names are intended to reduce confusion in the event of concurrent storms in the same Tropical cyclone basins, basin. Once storms develop sustained wind speeds of more than , names are generally assigned to them from predetermined lists, depending on the basin in which they originate. Some tropical depressions are named in the Western Pacific, while tropical cyclones must contain a significant amount of gale-force winds before they are named in the Southern Hemisphere. Before it became standard practice to give Given name, personal (first) names to tropical cyclones, they were named after places, objects, or the saints' feast days on which they occurred. Credit for the first usage of personal names for weather systems is generally given to Queensland Government meteorologist Clement Wr ...

Compressed Vowel
In phonetics, vowel roundedness is the amount of rounding in the lips during the articulation of a vowel. It is labialization of a vowel. When a ''rounded'' vowel is pronounced, the lips form a circular opening, and ''unrounded'' vowels are pronounced with the lips relaxed. In most languages, front vowels tend to be unrounded, and back vowels tend to be rounded. However, some languages, such as French, German and Icelandic, distinguish rounded and unrounded front vowels of the same height (degree of openness), and Vietnamese distinguishes rounded and unrounded back vowels of the same height. Alekano has only unrounded vowels. In the International Phonetic Alphabet vowel chart, rounded vowels are the ones that appear on the right in each pair of vowels. There are also diacritics, and , to indicate greater and lesser degrees of rounding, respectively. Thus has less rounding than cardinal , and has more (closer to the rounding of cardinal ). These diacritics can also be u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Phonetic Alphabet
The International Phonetic Alphabet (IPA) is an alphabetic system of phonetic notation based primarily on the Latin script. It was devised by the International Phonetic Association in the late 19th century as a standard written representation for the sounds of speech. The IPA is used by linguists, lexicography, lexicographers, foreign language students and teachers, speech–language pathology, speech–language pathologists, singers, actors, constructed language creators, and translators. The IPA is designed to represent those qualities of speech that are part of lexical item, lexical (and, to a limited extent, prosodic) sounds in oral language: phone (phonetics), phones, Intonation (linguistics), intonation and the separation of syllables. To represent additional qualities of speechsuch as tooth wikt:gnash, gnashing, lisping, and sounds made with a cleft lip and cleft palate, cleft palatean extensions to the International Phonetic Alphabet, extended set of symbols may be used ...

Beta (finance)
In finance, the beta ( or market beta or beta coefficient) is a statistic that measures the expected increase or decrease of an individual stock price in proportion to movements of the stock market as a whole. Beta can be used to indicate the contribution of an individual asset to the market risk of a portfolio when it is added in small quantity. It refers to an asset's non-diversifiable risk, systematic risk, or market risk. Beta is not a measure of idiosyncratic risk. Beta is the hedge ratio of an investment with respect to the stock market. For example, to hedge out the market-risk of a stock with a market beta of 2.0, an investor would short $2,000 in the stock market for every $1,000 invested in the stock. Thus insured, movements of the overall stock market no longer influence the combined position on average. Beta measures the contribution of an individual investment to the risk of the market portfolio that was not reduced by diversification. It does not measure the r ...

Greek Numerals
Greek numerals, also known as Ionic, Ionian, Milesian, or Alexandrian numerals, is a numeral system, system of writing numbers using the letters of the Greek alphabet. In modern Greece, they are still used for ordinal number (linguistics), ordinal numbers and in contexts similar to those in which Roman numerals are still used in the Western world. For ordinary cardinal number (linguistics), cardinal numbers, however, modern Greece uses Arabic numerals. History The Minoans, Minoan and Mycenaean civilizations' Linear A and Linear B alphabets used a different system, called Aegean numerals, which included number-only symbols for powers of ten: = 1, = 10, = 100, = 1000, and = 10000. Attic numerals composed another system that came into use perhaps in the 7th century BC. They were acrophonic, derived (after the initial one) from the first letters of the names of the numbers represented. They ran = 1, = ...

Cyclades
The CYCLADES computer network () was a French research network created in the early 1970s. It was one of the pioneering networks experimenting with the concept of packet switching and, unlike the ARPANET, was explicitly designed to facilitate internetworking. The CYCLADES network was the first to make the hosts responsible for the reliable delivery of data, rather than this being a centralized service of the network itself. Datagrams were exchanged on the network using transport protocols that do not guarantee reliable delivery, but only attempt best-effort. To empower the network leaves the hosts to perform error-correction, the network ensured end-to-end protocol transparency, a concept later to be known as the end-to-end principle. This simplified network design, reduced network latency, and reduced the opportunities for single point failures. The experience with these concepts led to the design of key features of the Internet Protocol in the ARPANET project. The network ...
