História das Palavras Cruzadas A contestação, com provas, da alegação feita pelo enigmista Henry Dudeney de que teria sido ele o criador do quadrado de palavras com definições em versos. Não Foi Ele, Não Desta vez ele errou O inglês Henry E. Dudeney formou, com o também inglês Lewis Carroll e o norte-americano Samuel Loyd, o trio de personalidades do enigmismo no final do século XIX. Embora nenhum deles tenha contribuído decisivamente para a história das palavras cruzadas, a sua dedicação aos quebra-cabeças, tanto lingüísticos quanto, nos casos de Dudeney e Loyd, matemáticos e espaciais, serviu para projetar essa atividade, antes associada apenas às mulheres, crianças e jovens. O norte-americano Samuel Loyd foi o pioneiro, entre os três. Nascido em 1841, já no final da década seguinte passava a dedicar-se exclusivamente à criação de passatempos, em especial os criados para anúncios de empresas norte-americanas. Alguns de seus quebra-cabeças ainda hoje desafiam a capacidade dos solucionadores, já que o criador nunca foi pródigo em explicações. Entre 1890 e 1911, ano de sua morte, Loyd rivalizou com o inglês Dudeney na disputa pelo título de mais famoso enigmista do mundo, sendo até mesmo acusado por Dudeney de apropriar-se de algumas de suas criações. Capa de livro de Sam Loyd O "Príncipe dos Enigmistas", como gostava de ser chamado, Loyd era acima de tudo um mestre do marketing. Sempre introduzia suas criações com uma história curiosa e fazia afirmações bombásticas e auto-elogiosas com grande freqüência. Chegou a dizer que havia vendido um bilhão de cópias de um de seus passatempos, o "Quebra-Cabeças do Pônei", em que as seis partes da figura, recortadas, deveriam ser recompostas para revelar um cavalo normal:

História das Palavras Cruzadas A troca de datas realizada pelo autor do artigo que divulgou os jogos do acróstico duplo na Inglaterra, erro cometido apenas 10 anos depois da publicação da matéria. Dá Para Acreditar? Quando a memória destoa da História Uma pesquisa histórica proporciona a oportunidade de aprendizado de várias lições. Uma delas é que nada substitui, em termos de fidelidade aos fatos, a consulta às chamadas "fontes primárias", ou seja, os documentos originais. Os historiadores, falíveis por natureza, cometem erros freqüentes quando baseiam suas afirmações em relatos alheios ou mesmo em lembranças pessoais de documentos antes consultados, não as comparando com o texto original no momento de redigir o seu trabalho. A solução para essas duas "ciladas" é uma só: procurar ao máximo de sua capacidade obter os documentos originais e sempre consultá-los diretamente, ao escrever sobre eles do ponto de vista fatual ou interpretativo. As informações existentes até o início de 2001, relativas ao primeiro jogo do acróstico duplo divulgado no Illustrated London News , davam conta de sua publicação em 30 de agosto de 1856.

Downloads Individual Magic Squares by Order: Regular Prime Pan-Magic Squares: Multiple Carpet Pan-Magic Squares: Website Home Page 4P+2 Magic Squares (6, 10 etc.): Benjamin Franklin's Magic Squares Amongst our forebears, some very distinguished names have played with magic squares. Benjamin Franklin is one example. He played with the construction of magic squares in 1736-37 when he was a clerk of the Pennsylvania Assembly. These two order eight squares are reproduced on pages 394 and 395 of the Papers of Benjamin Franklin Volume 3. Neither of these squares is Pan-magic, but a Spreadsheet Analysis of his squares makes it clear that he created them with a logical and structured underlying pattern. The coloring I used above emphasizes this logical pattern. Benjamin Franklin started his squares conventionally at 1, so the magic sum for his squares is 260. Henry Dudeney Writing in 1917 Dudeney said: "Of recent years many ingenious methods have been devised for the construction of magics (magic squares), and the law of their formation is so well understood that all the ancient mystery has evaporated and there is no longer any difficulty in making squares of any dimensions. Almost the last word has been said on this subject." (1) Almost, apparently, but not quite! He invalidated his own prediction almost immediately because he continued, himself, to write sufficient additional words on magic squares to cover several more pages.

Information on Pentomino Puzzles Description Example History Applications ... Links Description of the Problem A pentomino is an arrangement of 5 unit squares (or sometimes cubes) that are joined along their edges. Up to isomorphism (rotating and flipping), there are 12 possible shapes, which are illustrated below. Each piece is labelled by the letter that most accurately reflects its shape. V T W X U Z F P I N Y L The problem is to fit the 12 pentomino pieces into various shapes, often rectangles. The rectangular shapes that fit all 60 squares are of sizes 3x20, 4x15, 5x12, and 6x10. Example Here's a solution to the 6 by 10 puzzle using the letter encoding.

A Brief History The first published solution to a pentomino puzzle appeared in Henry Dudeney's The Canterbury Puzzles in 1907. Dudeney presented a solution to a puzzle of fitting the twelve pentomino shapes together with one square tetromino four squares joined together on a 8-by-8 checkerboard. This puzzle is considered the oldest of the pentomino puzzles and it comes with a fictional story. The story goes that the son of William the Conqueror and the dauphin of France were playing a game of chess when the dauphin threw the chessboard at his opponent in a fit of frustration. The son of William the Conqueror retaliated by breaking the chessboard over the dauphin's head, breaking the chessboard into thirteen pieces12 pentominoes and 1 tetrominowhich then had to be put back together.

70. Author Dicksie Dudeney -- Bio the Beast. My love of the supernatural continued to grow as I devoured storiesby Edgar Allan Poe, Nathaniel Hawthorne, J. Sheridan Le Fanu, henry James, HG http://www.dicksiedudeney.com/bio.html

From the moment I wrote my first "book" at the age of 6, I knew I had found my true path in life. Of course as it turned out, it was a long and circuitous path, but one I wouldn’t have missed for anything. I grew up on a Florida cattle ranch. As an only child, my playmates were motherless calves, lambs, wild hogs, chickens, armadillos, foxes, possums, raccoons, otters, and alligators. I rode a magnificent sorrel quarter horse and I used a cow whip with ease. I spoke a smattering of Miccosukee Seminole and even had the privilege of attending the Seminole’s sacred Green Corn Dance. It was a wonderful life, but one mostly lacking in human companionship. So to entertain myself, I created stories and peopled them with amazing characters. And because of that, I was never lonely. Like most solitary people, I also spent a good deal of time reading. Mostly, I read everything I could get my hands on, but my favorite works were in horror and dark fantasy. I suppose it all began when I fell in love with the Beast, from "Beauty and the Beast." My love of the supernatural continued to grow as I devoured stories by Edgar Allan Poe, Nathaniel Hawthorne, J. Sheridan Le Fanu, Henry James, H.G. Wells, Ambrose Bierce, H.P. Lovecraft, and Robert Bloch. I was, and am, totally addicted to monster movies and I revere Rod Serling and his Twilight Zone. I suppose given all that, I had no choice but to become a writer of weird tales myself.

72. Knuth: Recent News My recent trip to England allowed me to finish a longstanding project, to compilelists of several hundred columns that henry E. dudeney wrote for a newspaper http://www-cs-staff.stanford.edu/~knuth/news01.html

Recent News [click here to zip down to the schedule of public lectures] News flash (January 1): Happy New Year to all! One of my correspondents wrote that the new `millenium' began on January 1, 2000, but the new `millennium' begins today. Soon I will be years old, hexwise. My publishers at Addison-Wesley have risen to the occasion by putting together a splendid boxed set of the that summarize the results of my work on TeX and METAFONT. This is the first update of Volume D for many years, and it also includes many recent changes to The TeXbook and The METAFONTbook and to Computer Modern Typefaces, thanks to improvements suggested by thousands of volunteers all over the world. Nearly every page of these books has been changed since the first editions of 1986. So I urge everybody whose library has only the 1986 printings to ask their friendly librarian to obtain the new definitive set, and I also think everyone with more than a casual interest in digital typography will benefit from this upgraded set of books. The publishers and I have taken great care to dot all the i's and cross all the t's so that the books reach the highest standards of quality. Welcome, Kadin

Nacida en la casa de altos estudios más antigua de la Argentina, sus postulados de participación de los estudiantes en el gobierno de la Universidad, y su democratización alcanzaron trascendencia casi inmediata en varias universidades de América. Luego de aquel documento doctrinario, la Federación Universitaria Argentina -fundada en abril del 18- convocó al Primer Congreso Nacional de Estudiantes Universitarios, que funcionó desde el 20 al 31 de julio, con representantes de las cinco universidades del país: Buenos Aires, Córdoba, La Plata, Santa Fe y Tucumán. En estos debates nació el proyecto de ley de reforma universitaria, que establece los principios más conocidos: autonomía universitaria, gobierno tripartito (profesores, estudiantes y diplomados), implantación del régimen estrictamente democrático con participación igualitaria de los tres estados y renovación periódica de los cargos directivos.

The Zen of Magic Squares, Circles, and Stars: An Exhibition of Surprising Structures Across Dimensions Clifford A. Pickover Princeton University Press, 2002 "A refreshing new look at a timeless topic, brimming over with ideas, littered with surprising twists. Anyone who loves numbers, anyone who enjoys puzzles, will find The Zen of Magic Squares, Circles, and Stars compulsive (and compulsory!) reading." Ian Stewart, University of Warwick "At first glance magic squares may seem frivolous (Ben Franklin's opinion, even as he spent countless hours studying them!), but I think that is wrong. The great nineteenth-century German mathematician Leopold Kronecker said 'God Himself made the whole numberseverything else is the work of men,' and Cliff Pickover's stimulating book hints strongly at the possibility that God may have done more with the integers than just create them. I don't believe in magic in the physical world, but magic squares come as close as we will probably ever see to being mathematical magic." - Paul J.
