Dionysodorus Of Amisene
Dionysodorus of Amisene (1st century AD) was a Greek mathematician from Pontus (region), Pontus, now on the Black Sea coast of Turkey. He was briefly described by Strabo, as one of the learned men of the city of Amisus. Despite the similarity of his demonym to the inland city of Amaseia, where Strabo was born, translators H. C. Hamilton and W. Falconer instead footnote Amisus as being the modern city Samsun, near Amaseia on the coast. Amisene is a name for the region containing both cities. Strabo distinguishes him from Dionysodorus of Melos, a geometer, whom Pliny the Elder describes as having calculated the circumference of the Earth, less accurately than the older calculation of Eratosthenes. He should also be distinguished from Dionysodorus, Dionysodorus of Caunus, who studied conic sections. Primarily about Dionysodorus of Caunus, but briefly notes the Dionysodorus of Pliny's account, and states that Strabo distinguished Pliny's Dionysodorus from Dionysodorus of Amisene. Di ...

Pontus (region)
Pontus or Pontos (; ,) is a region on the southern coast of the Black Sea, located in the modern-day eastern Black Sea region of Turkey. The name was applied to the coastal region and its mountainous hinterland (rising to the Pontic Alps in the east) by the Greeks who colonized the area in the Archaic Greece, Archaic period and derived from the Greek name of the Black Sea: (), 'Hospitable Sea', or simply ''Pontos'' () as early as the Aeschylus, Aeschylean ''The Persians, Persians'' (472 BC) and Herodotus' ''Histories (Herodotus), Histories'' (). Having originally no specific name, the region east of the river Halys River, Halys was spoken of as the country ''()'', , and hence it acquired the name of Pontus, which is first found in Xenophon's ''Anabasis (Xenophon), Anabasis'' (). The extent of the region varied through the ages but generally extended from the borders of Colchis (modern western Georgia (country), Georgia) until well into Paphlagonia in the west, with varying amo ...

Black Sea
The Black Sea is a marginal sea, marginal Mediterranean sea (oceanography), mediterranean sea lying between Europe and Asia, east of the Balkans, south of the East European Plain, west of the Caucasus, and north of Anatolia. It is bounded by Bulgaria, Georgia (country), Georgia, Romania, Russia, Turkey, and Ukraine. The Black Sea is Inflow (hydrology), supplied by major rivers, principally the Danube, Dnieper and Dniester. Consequently, while six countries have a coastline on the sea, its drainage basin includes parts of 24 countries in Europe. The Black Sea, not including the Sea of Azov, covers , has a maximum depth of , and a volume of . Most of its coasts ascend rapidly. These rises are the Pontic Mountains to the south, bar the southwest-facing peninsulas, the Caucasus Mountains to the east, and the Crimean Mountains to the mid-north. In the west, the coast is generally small floodplains below foothills such as the Strandzha; Cape Emine, a dwindling of the east end ...

Strabo
Strabo''Strabo'' (meaning "squinty", as in strabismus) was a term employed by the Romans for anyone whose eyes were distorted or deformed. The father of Pompey was called "Gnaeus Pompeius Strabo, Pompeius Strabo". A native of Sicily so clear-sighted that he could see things at great distance as if they were nearby was also called "Strabo". (; ''Strábōn''; 64 or 63 BC) was an ancient Greece, ancient Greek geographer who lived in Anatolia, Asia Minor during the transitional period of the Roman Republic into the Roman Empire. He is best known for his work ''Geographica'', which presented a descriptive history of people and places from different regions of the world known during his lifetime. Additionally, Strabo authored historical works, but only fragments and quotations of these survive in the writings of other authors. Early life Strabo was born to an affluent family from Amasya, Amaseia in Kingdom of Pontus, Pontus in around 64BC. His family had been involved in politics s ...

Samsun
Samsun is a List of largest cities and towns in Turkey, city on the north coast of Turkey and a major Black Sea port. The urban area recorded a population of 738,692 in 2022. The city is the capital of Samsun Province which has a population of 1,382,376. The city is home to Ondokuz Mayıs University, several hospitals, three large shopping malls, Samsunspor football club, an opera house and a large and modern manufacturing district.

Pliny The Elder
Gaius Plinius Secundus (AD 23/24 79), known in English as Pliny the Elder ( ), was a Roman Empire, Roman author, Natural history, naturalist, and naval and army commander of the early Roman Empire, and a friend of the Roman emperor, emperor Vespasian. He wrote the encyclopedic (''Natural History''), a comprehensive thirty-seven-volume work covering a vast array of topics on human knowledge and the natural world, which became an editorial model for encyclopedias. He spent most of his spare time studying, writing, and investigating natural and geographic phenomena in the field. Among Pliny's greatest works was the twenty-volume ''Bella Germaniae'' ("The History of the German Wars"), which is Lost literary work, no longer extant. ''Bella Germaniae'', which began where Aufidius Bassus' ''Libri Belli Germanici'' ("The War with the Germans") left off, was used as a source by other prominent Roman historians, including Plutarch, Tacitus, and Suetonius. Tacitus may have used ''Bella Ger ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eratosthenes
Eratosthenes of Cyrene (; ; – ) was an Ancient Greek polymath: a Greek mathematics, mathematician, geographer, poet, astronomer, and music theory, music theorist. He was a man of learning, becoming the chief librarian at the Library of Alexandria. His work is comparable to the study of geography, and he introduced some of the terminology, even coining the terms geography and geographer. He is best known for being the first person known to calculate the Earth's circumference, which he did by using the extensive survey results he could access in his role at the Library. His calculation was remarkably accurate (his error margin turned out to be less than 1%). He was the first to calculate Earth's axial tilt, which similarly proved to have remarkable accuracy. He created the Eratosthenes' Map of the World, first global projection of the world, incorporating Circle of latitude, parallels and Longitude, meridians based on the available geographic knowledge of his era.

Dionysodorus
Dionysodorus of Caunus (, c. 250 BC – c. 190 BC) was an ancient Greek mathematician. Life and work Little is known about the life of Dionysodorus. Pliny the Elder writes about a Dionysodorus who measured the Earth's circumference, however he is probably the one from Melos and different both from the one from Caunus and from Dionysodorus of Amisene; Strabo differentiates between the latter two mathematicians. Dionysodorus is remembered for solving the cubic equation by means of the intersection of a rectangular hyperbola and a parabola. Eutocius credits Dionysodorus with the method of cutting a sphere into a given ratio, as described by him. Heron mentions a work by Dionysauras entitled ''On the Tore'', in which the volume of a torus is calculated and found to be equal to the area of the generating circle multiplied by the circumference of the circle created by tracing the center of the generating circle as it rotates about the torus's axis of revolution. Dionysodorus used A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conic Section
A conic section, conic or a quadratic curve is a curve obtained from a cone's surface intersecting a plane. The three types of conic section are the hyperbola, the parabola, and the ellipse; the circle is a special case of the ellipse, though it was sometimes considered a fourth type. The ancient Greek mathematicians studied conic sections, culminating around 200 BC with Apollonius of Perga's systematic work on their properties. The conic sections in the Euclidean plane have various distinguishing properties, many of which can be used as alternative definitions. One such property defines a non-circular conic to be the set of those points whose distances to some particular point, called a '' focus'', and some particular line, called a ''directrix'', are in a fixed ratio, called the ''eccentricity''. The type of conic is determined by the value of the eccentricity. In analytic geometry, a conic may be defined as a plane algebraic curve of degree 2; that is, as the ...

Herculaneum
Herculaneum is an ancient Rome, ancient Roman town located in the modern-day ''comune'' of Ercolano, Campania, Italy. Herculaneum was buried under a massive pyroclastic flow in the eruption of Mount Vesuvius in 79 AD. Like the nearby city of Pompeii, Herculaneum is famous as one of the few ancient cities to be preserved nearly intact, as the solidified material from the volcano that blanketed the town protected it against looting and the elements. Although less known than Pompeii today, it was the first and, for a long time, the only discovered Vesuvian city (in 1709). Pompeii was revealed in 1748 and identified in 1763. Unlike Pompeii, the mainly Pyroclastic rock, pyroclastic material that covered Herculaneum carbonization, carbonized and preserved more wooden objects such as roofs, beds, and doors, as well as other organic-based materials such as Herculaneum loaf, food and papyrus. According to the traditional tale, the city was rediscovered by chance in 1709 during the dri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
