Buxtehude
Buxtehude (), officially the Hanseatic City of Buxtehude (german: Hansestadt Buxtehude, nds, Hansestadt Buxthu ()), is a town on the Este River in Northern Germany, belonging to the district of Stade in Lower Saxony. It is part of the Hamburg Metropolitan Region and attached to the city's S-Bahn rapid transit network. Buxtehude is a medium-sized town and the second largest municipality in the Stade district (). It lies on the southern border of the Altes Land in close proximity to the city-state of Hamburg. To the west lie the towns of Horneburg and Stade and to the south there are a number of incorporated villages featuring mostly upscale housing; e.g., Ottensen and Apensen. History Early signs of settlements are the Daensen folding chair from a Bronze Age tumulus near Daensen and the Ovelgönne bread roll from the Pre-Roman Iron Age of Northern Europe, which was found in a loam mine in Ovelgönne. A settlement by the Este river is first recorded in 959. The manor of "B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mathematician
A mathematician is someone who uses an extensive knowledge of mathematics in their work, typically to solve mathematical problems. Mathematicians are concerned with numbers, data, quantity, structure, space, models, and change. History One of the earliest known mathematicians were Thales of Miletus (c. 624–c.546 BC); he has been hailed as the first true mathematician and the first known individual to whom a mathematical discovery has been attributed. He is credited with the first use of deductive reasoning applied to geometry, by deriving four corollaries to Thales' Theorem. The number of known mathematicians grew when Pythagoras of Samos (c. 582–c. 507 BC) established the Pythagorean School, whose doctrine it was that mathematics ruled the universe and whose motto was "All is number". It was the Pythagoreans who coined the term "mathematics", and with whom the study of mathematics for its own sake begins. The first woman mathematician recorded by history was Hypati ...

Computer (occupation)
The term "computer", in use from the early 17th century (the first known written reference dates from 1613), meant "one who computes": a person performing mathematical calculations, before electronic computers became commercially available. Alan Turing described the "human computer" as someone who is "supposed to be following fixed rules; he has no authority to deviate from them in any detail." Teams of people, often women from the late nineteenth century onwards, were used to undertake long and often tedious calculations; the work was divided so that this could be done in parallel. The same calculations were frequently performed independently by separate teams to check the correctness of the results. Since the end of the 20th century, the term "human computer" has also been applied to individuals with prodigious powers of mental arithmetic, also known as mental calculators. Origins in sciences Astronomers in Renaissance times used that term about as often as they called themse ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calendar (stationery)
A calendar is used to display dates and related information, usually in a table format. Calendars are used to plan future events and keep track of appointments, and so a typical calendar will include days of the week, week numbering, months, public holidays and clock changes. Printed calendars also often contain additional information relevant for specific groups – for instance, a Christian liturgical calendar will show holy days and liturgical colours, while a calendar for amateur astronomers will highlight phases of the moon, conjunctions and eclipses. Alongside their practical uses, calendars have taken on a decorative purpose, offering an easy way to introduce regularly changing artwork to a space, and have even influenced art and sexuality by popularizing the pin-up style. History Ancient documents and inscriptions, such as those from Rome and China, include early forms of calendars. Printing gave rise to many related types of publication which track dates, of which ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johann Halcke
Johann, typically a male given name, is the German form of ''Iohannes'', which is the Latin form of the Greek name ''Iōánnēs'' (), itself derived from Hebrew name ''Yochanan'' () in turn from its extended form (), meaning " Yahweh is Gracious" or "Yahweh is Merciful". Its English language equivalent is John. It is uncommon as a surname. People People with the name Johann include: Mononym *Johann, Count of Cleves (died 1368), nobleman of the Holy Roman Empire *Johann, Count of Leiningen-Dagsburg-Falkenburg (1662–1698), German nobleman *Johann, Prince of Hohenzollern-Sigmaringen (1578–1638), German nobleman A–K * Johann Adam Hiller (1728–1804), German composer * Johann Adam Reincken (1643–1722), Dutch/German organist * Johann Adam Remele (died 1740), German court painter * Johann Adolf I, Duke of Saxe-Weissenfels (1649–1697) * Johann Adolph Hasse (1699-1783), German Composer * Johann Altfuldisch (1911—1947), German Nazi SS concentration camp officer execute ...

Hamburg Mathematical Society
The Hamburg Mathematical Society (german: Mathematische Gesellschaft in Hamburg) is a learned society concerned with mathematics and located in the German city of Hamburg. It was founded in 1690 by Heinrich Meissner as the "Kunstrechnungsübende Societät". It is the oldest still-active mathematical society in the world, and the second-oldest scientific society in Germany after the Academy of Sciences Leopoldina, which was founded in 1652. Two asteroids, 449 Hamburga Hamburga (minor planet designation: 449 Hamburga) is a carbonaceous asteroid from the background population of the intermediate asteroid belt, approximately 75 kilometers in diameter. It was discovered by German astronomers Max Wolf and Friedric ... and 454 Mathesis, were given their names at an anniversary celebration of the society in 1901.

Euler Brick
In mathematics, an Euler brick, named after Leonhard Euler, is a rectangular cuboid whose edges and face diagonals all have integer lengths. A primitive Euler brick is an Euler brick whose edge lengths are relatively prime. A perfect Euler brick is one whose space diagonal is also an integer but such a brick has not yet been found. Definition The definition of an Euler brick in geometric terms is equivalent to a solution to the following system of Diophantine equations: :\begin a^2 + b^2 = d^2\\ a^2 + c^2 = e^2\\ b^2 + c^2 = f^2\end where are the edges and are the diagonals. Properties * If is a solution, then is also a solution for any . Consequently, the solutions in rational numbers are all rescalings of integer solutions. Given an Euler brick with edge-lengths , the triple constitutes an Euler brick as well.Wacław Sierpiński, ''Pythagorean Triangles'', Dover Publications, 2003 (orig. ed. 1962). * Exactly one edge and two face diagonals of a ''primitive'' Euler ...

18th-century German Mathematicians
The 18th century lasted from January 1, 1701 ( MDCCI) to December 31, 1800 ( MDCCC). During the 18th century, elements of Enlightenment thinking culminated in the American, French, and Haitian Revolutions. During the century, slave trading and human trafficking expanded across the shores of the Atlantic, while declining in Russia, China, and Korea. Revolutions began to challenge the legitimacy of monarchical and aristocratic power structures, including the structures and beliefs that supported slavery. The Industrial Revolution began during mid-century, leading to radical changes in human society and the environment. Western historians have occasionally defined the 18th century otherwise for the purposes of their work. For example, the "short" 18th century may be defined as 1715–1789, denoting the period of time between the death of Louis XIV of France and the start of the French Revolution, with an emphasis on directly interconnected events.

1662 Births
Year 166 ( CLXVI) was a common year starting on Tuesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Pudens and Pollio (or, less frequently, year 919 ''Ab urbe condita''). The denomination 166 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years. Events By place Roman Empire * Dacia is invaded by barbarians. * Conflict erupts on the Danube frontier between Rome and the Germanic tribe of the Marcomanni. * Emperor Marcus Aurelius appoints his sons Commodus and Marcus Annius Verus as co-rulers (Caesar), while he and Lucius Verus travel to Germany. * End of the war with Parthia: The Parthians leave Armenia and eastern Mesopotamia, which both become Roman protectorates. * A plague (possibly small pox) comes from the East and spreads throughout the Roman Empire, lasting for roughly twenty years. * The ...
