Egg Of Columbus
An egg of Columbus or Columbus' egg ( it, uovo di Colombo ) refers to a brilliant idea or discovery that seems simple or easy after the fact. The expression refers to an apocryphal story, dating from at least the 16th century, in which it is said that Christopher Columbus, having been told that finding a new trade route was inevitable and no great accomplishment, challenges his critics to make an egg stand on its tip. After his challengers give up, Columbus does it himself by tapping the egg on the table to flatten its tip. The story is often alluded to when discussing creativity. The term has also been used as the trade name of a tangram puzzle and several mechanical puzzles. It also shows that anything can be done by anyone with the right set of skills; however, not everyone knows how to do it. Source of the story The Columbus egg story may have originated with Italian historian and traveler Girolamo Benzoni. In his book ''History of the New World'', published in 1565, he ...

Egg Of Columbus (tangram Puzzle)
The Egg of Columbus (''Ei des Columbus'' in German language, German) is a puzzle consisting of a flat egg (food), egg-like shape divided into 9 or 10 pieces by straight cuts. The goal of the puzzle is to rearrange the pieces so as to form other specific shapes, as in a tangram. The earliest known examples were produced by Richter (toy company), Richter, a German toy manufacturer. Production ceased in 1963, but restarted near the start of the 21st century.Put-Together - Ei Des Columbus aka Egg of Columbus accessed 2008-10-11 Because the two pieces coloured turquoise in these diagrams lack bilateral symmetry, some shapes in which both pieces have the same chirality, as in two of the examples below, require one of them to be flipped over.

It is considered by many academics to have been the birthplace of the Renaissance, becoming a major artistic, cultural, commercial, political, economic and financial center. During this time, Florence rose to a position of enormous influence in Italy, Europe, and beyond. Its turbulent political history includes periods of rule by the powerful House of Medici, Medici family and numerous religious and republican revolutions. From 1865 to 1871 the city served as the capital of the Kingdom of Italy (established in 1861). The Florentine dialect forms the base of Italian language, Stan ...

Rotating Magnetic Field
A rotating magnetic field is the resultant magnetic field produced by a system of coils symmetrically placed and supplied with polyphase currents. A rotating magnetic field can be produced by a poly-phase (two or more phases) current or by a single phase current provided that, in the latter case, two field windings are supplied and are so designed that the two resulting magnetic fields generated thereby are out of phase. Rotating magnetic fields are often utilized for electromechanical applications, such as induction motors, electric generators and induction regulators. History In 1824, the French physicist François Arago formulated the existence of rotating magnetic fields using a rotating copper disk and a needle, termed “ Arago's rotations.” English experimenters Charles Babbage and John Herschel found they could induce rotation in Arago's copper disk by spinning a horseshoe magnet under it, with English scientist Michael Faraday later attributing the effect to electrom ...

Tesla's Egg Of Columbus
Tesla's Egg of Columbus was a device exhibited in the Westinghouse Electric display at the 1893 Chicago World's Columbian Exposition to explain the rotating magnetic field that drove the new alternating current induction motors designed by inventor Nikola Tesla by using that magnetic field to spin a copper egg on end. Origins At the 1893 World's Columbian Exposition Westinghouse Electric (who had a large space in the "Electricity Building" devoted to their electrical exhibits) asked Tesla to participate and gave his devices their own exhibit space. The display demonstrated a series of electrical effects related to alternating current, AC generators, and displayed many types of induction motors and explained the rotating magnetic field that drove them. With the fair celebrating the 400th anniversary of Christopher Columbus's arrival in the New World, the "Egg of Columbus" exhibit, building on the apocryphal 15th century story of the "Egg of Columbus" (where the explorer stood a ...

World's Columbian Exposition
The World's Columbian Exposition (also known as the Chicago World's Fair) was a world's fair held in Chicago in 1893 to celebrate the 400th anniversary of Christopher Columbus's arrival in the New World in 1492. The centerpiece of the Fair, held in Jackson Park, was a large water pool representing the voyage Columbus took to the New World. Chicago had won the right to host the fair over several other cities, including New York City, Washington, D.C., and St. Louis. The exposition was an influential social and cultural event and had a profound effect on American architecture, the arts, American industrial optimism, and Chicago's image. The layout of the Chicago Columbian Exposition was, in large part, designed by John Wellborn Root, Daniel Burnham, Frederick Law Olmsted and Charles B. Atwood. It was the prototype of what Burnham and his colleagues thought a city should be. It was designed to follow Beaux-Arts principles of design, namely neoclassical architecture principles b ...

Westinghouse Electric Corporation
The Westinghouse Electric Corporation was an American manufacturing company founded in 1886 by George Westinghouse. It was originally named "Westinghouse Electric & Manufacturing Company" and was renamed "Westinghouse Electric Corporation" in 1945. The company acquired the CBS television network in 1995 and was renamed "CBS Corporation" until being acquired by Viacom in 1999, a merger completed in April 2000. The CBS Corporation name was later reused for one of the two companies resulting from the split of Viacom in 2006. The Westinghouse trademarks are owned by Westinghouse Electric Corporation, and were previously part of Westinghouse Licensing Corporation. The nuclear power business, Westinghouse Electric Company, was spun off from the Westinghouse Electric Corporation in 1999.

Charles Darwin
Charles Robert Darwin ( ; 12 February 1809 – 19 April 1882) was an English naturalist, geologist, and biologist, widely known for his contributions to evolutionary biology. His proposition that all species of life have descended from a common ancestor is now generally accepted and considered a fundamental concept in science. In a joint publication with Alfred Russel Wallace, he introduced his scientific theory that this branching pattern of evolution resulted from a process he called natural selection, in which the struggle for existence has a similar effect to the artificial selection involved in selective breeding. Darwin has been described as one of the most influential figures in human history and was honoured by burial in Westminster Abbey. Darwin's early interest in nature led him to neglect his medical education at the University of Edinburgh; instead, he helped to investigate marine invertebrates. His studies at the University of Cambridge's Christ's ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
War And Peace
''War and Peace'' (russian: Война и мир, translit=Voyna i mir; pre-reform Russian: ; ) is a literary work by the Russian author Leo Tolstoy that mixes fictional narrative with chapters on history and philosophy. It was first published serially, then published in its entirety in 1869. It is regarded as Tolstoy's finest literary achievement and remains an internationally praised classic of world literature. The novel chronicles the French invasion of Russia and the impact of the Napoleonic era on Tsarist society through the stories of five Russian aristocratic families. Portions of an earlier version, titled ''The Year 1805'', were serialized in ''The Russian Messenger'' from 1865 to 1867 before the novel was published in its entirety in 1869.Knowles, A. V.

Leo Tolstoy
Count Lev Nikolayevich TolstoyTolstoy pronounced his first name as , which corresponds to the romanization ''Lyov''. () (; russian: link=no, Лев Николаевич Толстой,In Tolstoy's day, his name was written as in pre-reformed Russian. ; ), usually referred to in English as Leo Tolstoy, was a Russian writer who is regarded as one of the greatest authors of all time. He received nominations for the Nobel Prize in Literature every year from 1902 to 1906 and for the Nobel Peace Prize in 1901, 1902, and 1909; the fact that he never won is a major controversy. Born to an aristocratic Russian family in 1828, Tolstoy's notable works include the novels ''War and Peace'' (1869) and ''Anna Karenina'' (1878), often cited as pinnacles of realist fiction. He first achieved literary acclaim in his twenties with his semi-autobiographical trilogy, ''Childhood'', '' Boyhood'', and ''Youth'' (1852–1856), and '' Sevastopol Sketches'' (1855), based upon his experiences in ...

Frankenstein
''Frankenstein; or, The Modern Prometheus'' is an 1818 novel written by English author Mary Shelley. ''Frankenstein'' tells the story of Victor Frankenstein, a young scientist who creates a sapient creature in an unorthodox scientific experiment. Shelley started writing the story when she was 18, and the first edition was published anonymously in London on 1 January 1818, when she was 20. Her name first appeared in the second edition, which was published in Paris in 1821. Shelley travelled through Europe in 1815, moving along the river Rhine in Germany, and stopping in Gernsheim, away from Frankenstein Castle, where, two centuries before, an alchemist had engaged in experiments.This seems to mean Johann Konrad Dippel (1673–1734), one century before (not two). For Dippel's experiments and the possibility of connection to ''Frankenstein'' see the Dippel article. She then journeyed to the region of Geneva, Switzerland, where much of the story takes place.
