Euphonia (device)
The Euphonia was a talking machine created in the early to mid-nineteenth century by the Austrian inventor Joseph Faber and exhibited in 1845 in Philadelphia and in 1846 in London's Egyptian Hall. An earlier version of the invention had been destroyed in 1844 by Faber. Construction A mechanical device that he had reportedly spent over twenty-five years developing, Faber's "Fabulous Talking Machine" was constructed of several different mechanisms and instruments: a piano, a bellows, and a mechanical replica of the human throat and vocal organs. By pressing the keys on the keyboard, a human operator produced sounds that inflated the bellows and caused the mechanical mouth to open, the mechanical tongue to be lifted, and the mechanical jaws to move. Able to produce sentences in English, French, and German, the Euphonia was reported by ''The London Journal'' to speak all three with a German accent, a fact attributed to the native language (German) of the inventor. It was P.T. Barn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Euphonia
Euphonias are members of the genus ''Euphonia'', a group of Neotropical birds in the finch family. They and the chlorophonias comprise the subfamily Euphoniinae. The genus name is of Greek origin and refers to the birds' pleasing song, meaning "sweet-voiced" ( ''eu'' means "well" or "good" and ''phōnē'' means "sound", hence "of good sound"). Most male euphonias are dark metallic blue above and bright yellow below. Many have contrasting pale foreheads and white undertails. Some have light blue patches on the head and/or orangish underparts. Females much more plain, predominantly olive-green all over. They range in overall length from . They eat small fruit and berries, particularly mistletoe (Loranthaceae). Some species may also eat some insects. Euphonias were once considered members of the tanager family, Thraupidae. A molecular phylogenetic study of the finch family Fringillidae published in 2012 included 9 species from the genus ''Euphonia'' and a single species from the ...

Machine
A machine is a physical system using Power (physics), power to apply Force, forces and control Motion, movement to perform an action. The term is commonly applied to artificial devices, such as those employing engines or motors, but also to natural biological macromolecules, such as molecular machines. Machines can be driven by Animal power, animals and Human power, people, by natural forces such as Wind power, wind and Water power, water, and by Chemical energy, chemical, Thermal energy, thermal, or electricity, electrical power, and include a system of mechanism (engineering), mechanisms that shape the actuator input to achieve a specific application of output forces and movement. They can also include computers and sensors that monitor performance and plan movement, often called mechanical systems. Renaissance natural philosophers identified six simple machines which were the elementary devices that put a load into motion, and calculated the ratio of output force to input fo ...

Philadelphia
Philadelphia, often called Philly, is the largest city in the Commonwealth of Pennsylvania, the sixth-largest city in the U.S., the second-largest city in both the Northeast megalopolis and Mid-Atlantic regions after New York City. Since 1854, the city has been coextensive with Philadelphia County, the most populous county in Pennsylvania and the urban core of the Delaware Valley, the nation's seventh-largest and one of world's largest metropolitan regions, with 6.245 million residents . The city's population at the 2020 census was 1,603,797, and over 56 million people live within of Philadelphia. Philadelphia was founded in 1682 by William Penn, an English Quaker. The city served as capital of the Pennsylvania Colony during the British colonial era and went on to play a historic and vital role as the central meeting place for the nation's founding fathers whose plans and actions in Philadelphia ultimately inspired the American Revolution and the nation's inde ...

London
London is the capital and largest city of England and the United Kingdom, with a population of just under 9 million. It stands on the River Thames in south-east England at the head of a estuary down to the North Sea, and has been a major settlement for two millennia. The City of London, its ancient core and financial centre, was founded by the Romans as '' Londinium'' and retains its medieval boundaries.See also: Independent city § National capitals The City of Westminster, to the west of the City of London, has for centuries hosted the national government and parliament. Since the 19th century, the name "London" has also referred to the metropolis around this core, historically split between the counties of Middlesex, Essex, Surrey, Kent, and Hertfordshire, which largely comprises Greater London, governed by the Greater London Authority.The Greater London Authority consists of the Mayor of London and the London Assembly.

Egyptian Hall
The Egyptian Hall in Piccadilly, London, was an exhibition hall built in the ancient Egyptian style in 1812, to the designs of Peter Frederick Robinson. The Hall was a considerable success, with exhibitions of artwork and of Napoleonic era relics. The hall was later used for popular entertainments and lectures, and developed an association with magic and spiritualism, becoming known as "England's Home of Mystery". In 1905, the building was demolished to make way for flats and offices. History The Egyptian Hall was commissioned by William Bullock as a museum to house his collection, which included curiosities brought back from the South Seas by Captain Cook. It was completed in 1812 at a cost of £16,000. It was the first building in England to be influenced by the Egyptian style, partly inspired by the success of the Egyptian Room in Thomas Hope's house in Duchess Street, which was open to the public and had been well illustrated in Hope's ''Household Furniture and Inte ...

Piano
The piano is a stringed keyboard instrument in which the strings are struck by wooden hammers that are coated with a softer material (modern hammers are covered with dense wool felt; some early pianos used leather). It is played using a keyboard, which is a row of keys (small levers) that the performer presses down or strikes with the fingers and thumbs of both hands to cause the hammers to strike the strings. It was invented in Italy by Bartolomeo Cristofori around the year 1700. Description The word "piano" is a shortened form of ''pianoforte'', the Italian term for the early 1700s versions of the instrument, which in turn derives from ''clavicembalo col piano e forte'' (key cimbalom with quiet and loud)Pollens (1995, 238) and ''fortepiano''. The Italian musical terms ''piano'' and ''forte'' indicate "soft" and "loud" respectively, in this context referring to the variations in volume (i.e., loudness) produced in response to a pianist's touch or pressure on the keys: the grea ...

Bellows
A bellows or pair of bellows is a device constructed to furnish a strong blast of air. The simplest type consists of a flexible bag comprising a pair of rigid boards with handles joined by flexible leather sides enclosing an approximately airtight cavity which can be expanded and contracted by operating the handles, and fitted with a valve allowing air to fill the cavity when expanded, and with a tube through which the air is forced out in a stream when the cavity is compressed. xford English Dictionary, 2nd ed: bellows/ref> It has many applications, in particular blowing on a fire to supply it with air. The term "bellows" is used by extension for a flexible bag whose volume can be changed by compression or expansion, but not used to deliver air. For example, the light-tight (but not airtight) bag allowing the distance between the lens and film of a folding photographic camera to be varied is called a bellows. Etymology "Bellows" is only used in plural. The Old English name ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Speech Organ
The field of articulatory phonetics is a subfield of phonetics that studies articulation and ways that humans produce speech. Articulatory phoneticians explain how humans produce speech sounds via the interaction of different physiological structures. Generally, articulatory phonetics is concerned with the transformation of aerodynamic energy into acoustic energy. Aerodynamic energy refers to the airflow through the vocal tract. Its potential form is air pressure; its kinetic form is the actual dynamic airflow. Acoustic energy is variation in the air pressure that can be represented as sound waves, which are then perceived by the human auditory system as sound. Respiratory sounds can be produced by expelling air from the lungs. However, to vary the sound quality in a way useful for speaking, two speech organs normally move towards each other to contact each other to create an obstruction that shapes the air in a particular fashion. The point of maximum obstruction is called the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hector Berlioz
In Greek mythology, Hector (; grc, Ἕκτωρ, Hektōr, label=none, ) is a character in Homer's Iliad. He was a Trojan prince and the greatest warrior for Troy during the Trojan War. Hector led the Trojans and their allies in the defense of Troy, killing countless Greek warriors. He was ultimately killed in single combat by Achilles, who later dragged his dead body around the city of Troy behind his chariot. Etymology In Greek, is a derivative of the verb ἔχειν ''ékhein'', archaic form * grc, ἕχειν, hékhein, label=none ('to have' or 'to hold'), from Proto-Indo-European *'' seɡ́ʰ-'' ('to hold'). , or as found in Aeolic poetry, is also an epithet of Zeus in his capacity as 'he who holds verything together. Hector's name could thus be taken to mean 'holding fast'. Description Hector was described by the chronicler Malalas in his account of the ''Chronography'' as "dark-skinned, tall, very stoutly built, strong, good nose, wooly-haired, good beard, sq ...

Turks (term For Muslims)
The ethnonym Turks ( gr, Τούρκοι/''Tourkoi'', sh, Turci/, sq, turk) has been commonly used by the non-Muslim Balkan peoples to denote all Muslim settlers in the region, regardless of their ethno-linguistic background. The majority of these, however, were indeed ethnic Turks. In the Ottoman Empire, the Islamic faith was the official religion, with Muslims holding different rights than non-Muslims. Non-Muslim (''dhimmi'') ethno-religious legal groups were identified by different ''millets'' ("nations"). ''Turk'' was also notably used to denote all groups in the region who had been Islamized during the Ottoman rule, especially Muslim Albanians and Slavic Muslims (mostly Bosniaks). For the Balkan Christians, converting to Islam was synonymous with Turkification, succumbing to "Ottoman rule and embracing the Ottoman way of life," hence "to become a Turk". In South Slavic languages, there are also derivative terms that are more-so seen as offensive towards Bosniaks, such as ''pot ...

Joseph Henry
Joseph Henry (December 17, 1797– May 13, 1878) was an American scientist who served as the first Secretary of the Smithsonian Institution. He was the secretary for the National Institute for the Promotion of Science, a precursor of the Smithsonian Institution. He was highly regarded during his lifetime. While building electromagnets, Henry discovered the electromagnetic phenomenon of self-inductance. He also discovered mutual inductance independently of Michael Faraday, though Faraday was the first to make the discovery and publish his results. Henry developed the electromagnet into a practical device. He invented a precursor to the electric doorbell (specifically a bell that could be rung at a distance via an electric wire, 1831) and electric relay (1835). His work on the electromagnetic relay was the basis of the practical electrical telegraph, invented by Samuel F. B. Morse and Sir Charles Wheatstone, separately. In his honor the SI unit of inductance is named the henry (p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Automaton
An automaton (; plural: automata or automatons) is a relatively self-operating machine, or control mechanism designed to automatically follow a sequence of operations, or respond to predetermined instructions.Automaton – Definition and More from the Free Merriam-Webster Dictionary http://www.merriam-webster.com/dictionary/automaton Some automata, such as Jacquemart (bellstriker), bellstrikers in mechanical clocks, are designed to give the illusion to the casual observer that they are operating under their own power. Since long ago, the term is commonly associated with automated puppets that resemble moving humans or animals, built to impress and/or to entertain people. Animatronics are a modern type of automata with electronics, often used for the portrayal of characters in films and in theme park attractions. Etymology The word "automaton" is the latinization of the Ancient Greek , , (neuter) "acting of one's own will". This word was first used by Homer to describe an auto ...
