Beta
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 ...

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 ...

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 ...

Greek Alphabet
The Greek alphabet has been used to write the Greek language since the late 9th or early 8th century BC. It was derived from the earlier Phoenician alphabet, and is the earliest known alphabetic script to systematically write vowels as well as consonants. In Archaic Greece, Archaic and early Classical Greece, Classical times, the Greek alphabet existed in Archaic Greek alphabets, many local variants, but, by the end of the 4th century BC, the Ionia, Ionic-based Euclidean alphabet, with 24 letters, ordered from alpha to omega, had become standard throughout the Greek-speaking world and is the version that is still used for Greek writing today. The letter case, uppercase and lowercase forms of the 24 letters are: : , , , , , , , , , , , , , , , , , , , , , , , The Greek alphabet is the ancestor of several scripts, such as the Latin script, Latin, Gothic alphabet, Gothic, Coptic script, Coptic, and Cyrillic scripts.

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 Storm Beta (2020)
Tropical Storm Beta was a tropical cyclone that brought heavy rainfall, flooding, and severe weather to the Southeastern United States in September 2020. The twenty-fourth tropical depression and twenty-third named storm of the record-breaking 2020 Atlantic hurricane season, Beta originally formed from a trough of low pressure that developed in the northeastern Gulf of Mexico on September 10. The low moved slowly southwestward, with development hampered initially by the development of nearby Hurricane Sally. After Sally moved inland over the Southeastern United States and weakened, the disturbance became nearly stationary in the southwestern Gulf, where it began to organize. By September 16, the storm had gained a low-level circulation center and had enough organization to be designated as ''Tropical Depression Twenty-Two''. The system held its intensity for a day due to the influence of strong wind shear and dry air, before eventually attaining tropical storm st ...

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, = ...

Voiced Bilabial Fricative
The voiced bilabial fricative is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is , and the equivalent X-SAMPA symbol is B. The official symbol is the Greek letter beta. This letter is also often used to represent the bilabial approximant, though that is more precisely written with a lowering diacritic, that is . That sound may also be transcribed as an advanced labiodental approximant , in which case the diacritic is again frequently omitted, since no contrast is likely. It has been proposed that either a turned , reversed or affricate can be used as a dedicated symbol for the bilabial approximant, but despite occasional usage none of them have gained general acceptance. It is extremely rare for a language to make a phonemic contrast between the voiced bilabial fricative and the bilabial approximant. The Mapos Buang language of New Guinea contains this contrast. Its bilabial appr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ve (Cyrillic)
Ve (В в; italics: ''В'' ''в'') is a letter of the Cyrillic script. It commonly represents the voiced labiodental fricative , like in "vase". It can also represent . The capital letter Ve Homoglyph, looks the same as the capital B, Latin letter B but is pronounced differently. Ve is commonly romanized by the V, Latin letter V (as described by ISO 9), but sometimes the W, Latin letter W is used instead, such as in Polish language, Polish, or by the German language, German Duden transcription. History Both Ve and the Be (Cyrillic), Cyrillic letter Be (Б б) were derived from the Beta (letter), Greek letter Beta (Β β), which already represented in Greek by the time the Cyrillic alphabet was created. In the Early Cyrillic alphabet, its name was (''vědě''), meaning "I know". In the old Russian alphabet the name was ''vedi''. In the Cyrillic numerals, Cyrillic numeral system, it had the value of 2.

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 ...

Acrophony
Acrophony (; + 'sound') is the naming of letters of an alphabetic writing system so that a letter's name begins with the letter itself. For example, Greek letter names are acrophonic: the names of the letters α, β, γ, δ, are spelled with the respective letters: (), (), (), (). The paradigm for acrophonic alphabets is the Proto-Sinaitic script and the succeeding Phoenician alphabet, in which the letter A, representing the sound , is thought to have derived from an Egyptian hieroglyph representing an ox, and is called 'ox', , which starts with the glottal stop sound the letter represents. The second letter of the Phoenician alphabet is ''bet'' (which means 'house' and looks a bit like a shelter) representing the sound and from ''ālep-bēt'' came the word "alphabet"another case where the beginning of a thing gives the name to the whole, which was in fact common practice in the ancient Near East.

Be (Cyrillic)
Be (Б б; italics: ) is a letter of the Cyrillic script. It commonly represents the voiced bilabial plosive , like the English pronunciation of in "ball". It should not be confused with the Ve (Cyrillic), Cyrillic letter Ve (В в), which is shaped like Latin capital letter B but represents the voiced labiodental fricative or the voiced bilabial fricative . The Cyrillic letter Б (Be) is romanized using the Latin letter . History The Cyrillic letters Be and Ve (Cyrillic), Ve (В в) were both derived from the Greek letter Beta (Β β). In the Early Cyrillic alphabet the name of the letter Be was (''buky''/), meaning "letter". In the Cyrillic numerals, Cyrillic numeral system, the letter Be had no numeric value because the letter Ve inherited the Greek letter Beta's numeric value. Form The Russian small letter (be) is similar (but not identical) in shape to the 6, digit 6. Its lowercase form also somewhat resembles a lowercase letter B ("b"), the ...
