63. John Napier And Logarithms john (1593)! john napier. john napier, Mirifici logarithmorum canonis descriptio(1614) (from the preface of the first English translation in 1616). http://www.ualr.edu/~lasmoller/napier.html

Did you know . . .? Long before the calculator, logarithms were great mathematical labor-saving devices! Although there is evidence that logarithms were known in 8th century India, their invention as an aid to calculation is attributed to a Scottish nobleman named John Napier (1550-1617) in his Mirifici logarithmorum canonis descriptio (1614) and Mirifici logarithmorum canonis constructio (published posthumously in 1619). In collaboration with Oxford professor Henry Briggs, Napier refined his logarithms by constructing tables for logarithms in base 10. Napier is also credited with creating one of the earliest calculating machines ( "Napier's bones" ) and with the first systematic use of the decimal point Not a bad mathematical pedigree for a man who never finished university and who considered his most important work to be his Plaine Discovery of the Whole Revelation of St. John John Napier. (Source: http://www-history.mcs.st-and.ac.uk/history/PictDisplay/Napier.html Napier lived during an age of great innovation in the world of astronomy. Copernicus had published his theory of the solar system in 1543, and many astronomers were eagerly involved in calculating and re-calculating planetary positions based in the wake of Copernicus's ideas. Their calculations took up pages and pages and hours and hours of work.

Alessandro Home Page John Napier Napier e os logaritmos John Napier era um proprietário escocês , Barão de Murchiston, que administrava suas grandes propriedades e escrevia sobre vários assuntos. Ele só se interessava por alguns aspectos da matemática, particularmente os que se referiam a computação e a trigonometria. Napier conta que trabalhou em sua invenção dos logaritmos durante vinte anos antes de publicar seus resultados(1.614). Napier começou a reduzir operações tediosas de multiplicação a operações mais simples de adição através da correspondência entre progressões ariméticas e geométricas. Para entender como, vamos considerar um exemplo simples, que aparece num trabalho de Michael Stiefell, em 1544, onde ele coloca lado a lado as seguintes progressões aritmética e geométrica PA PG Aí ele observa que a adição na PA corresponde a multiplicação na PG. Por exemplo : Quando voce faz a conta 2 a b a+b , você está resolvendo uma conta de multiplicação através de uma soma, já que você está simplesmente somando os expoentes. Assim , uma maneira de reduzir o processo de multiplicação de dois números a uma soma, é escrever os números como potencias de mesma base. Será isso possível? Napier usou uma PG de razão 0,9999999 ( 1- 10

Napier invented or proposed several military inventions: burning mirrors to set enemy ships on fire, special artillery that destroyed everything within a radius of four miles, bulletproof clothing, an early version of the tank, and a submarine-like device. John Napier also invented a hydraulic screw with a revolving axle for use in coal pits to lower water levels and Napier also worked on agricultural innovations to improve crops with manures and salt. John Napier John Napier is best known for his invention of logarithms. His other mathematical contributions include: a mnemonic for formulas used in solving spherical triangles, two formulas known as Napier's analogies used in solving spherical triangles, an invention called Napier's bones used for mechanically multiplying dividing and taking square roots and cube roots, exponential expressions for trigonometric functions, and the decimal notation for fractions.

Gazetteer for Scotland Help ... Add Comment Sir John Napier John Napier of Merchiston Mathematician, inventor and astronomer. Born at Merchiston Castle (Edinburgh) into a wealthy family, Napier was the eldest son of Sir Archibald Napier (1534 - 1608). He was educated at St. Salvator's College, St. Andrews and became a staunch Calvinist. He devised "Napier's Rods" or "Napier's Bones" which permitted easy multiplication by addition. This led to his best remembered work: the concept of logarithms, which he described in Mirifici Logarithmorum Canonis Descriptio (1614). He also invented the decimal point and a hydraulic screw pump to remove water from coal mines. Napier also proposed a number of new weapons, including a device based on mirrors to set fire to enemy ships by focussing a high-intensity light beam, an armoured wagon and a submarine. He also experimented in agricultural improvement on his estates. His son to his first wife, Elizabeth, became the first Lord Napier. In 1572, he married Agnes Chisholm and they settled on his family estate at Gartness, near Killearn (Stirling). Napier was buried at St. Cuthbert's Church in Edinburgh.

John Napier Domovská stránka Fyzici John Napier se narodil v roce 1550 na zámku Merchiston Castle ve skotském Edinburghu. Rodina jeho otce (Archibald Napier) vlastnila od 15. století panství Merchiston. Archibald Napier se v pouhých 15 letech oženil se sestrou biskupa z Orkney s Janet Bothwellovou. O rok pozdìji se narodil John. Jméno John Napier se vyskytuje nejèastìji právì v podobì John Napier. V dobì života Johna Napiera se však èasto používalo také staršího Jhone. Jeho pøíjmení se také psalo Naipper, Napare, Naper, Nepair, Napeir, Nepeir, Neper. Nejèastìji se jeho jméno psalo Jhone Neper . Zápis John Napier odpovídá souèasnosti. Ve svých spisech se Napier podepisoval také latinskou formou Ioanne Napero Tøináctiletý John Napier zaèal od roku 1563 studovat na universitì St. Andrews. Krátce po zaèátku studia Napierova matka umírá. Jméno John Napier, ale není uvedeno na seznamech absolventù St. Andrews. Napier totiž odešel studovat do Evropy. O jeho pobytu v Evropì však neexistují žádné záznamy. V roce 1571 se Napier vrátil do Skotska. Od roku 1574 Napier žil Napier na novì dokonèeném zámku v Gartness. Napier se vìnoval øízení svých panství. Své vìdecké znalosti dal do správy svého majetku. Mj. experimentoval s vìdeckými metodami v zemìdìlství.

Back to the Table of Contents Biographies of Mathematicians - John Napier Napier is best known for his invention of logarithms and for formulas used in solving spherical triangles. Napier was born in the Tower of Merchiston, now at the center of Napier University’s Merchiston campus, in 1550. At the age of 13 he went to St. Andrews studying at St. Salvator’s College for two years. It is thought he travelled in Europe between 1566-1571 perhaps studying in Paris or Holland but there is no corroborative evidence of this. He had a son called Archibald to his first wife Elizabeth, who became the first Lord Napier. He also had a daughter called Janet, about whom nothing is known beyond that. In 1572 he married his second wife Agnes Chisholm and they settled on his family estate at Gartness in Stirlingshire, bringing up five more sons and five daughters. Napier died in April 1617 and was buried at St. Cuthbert’s Church in Edinburgh. In his lifetime he was known as the Marvellous Merchiston, a well-deserved title, for his genius and imaginative vision encompassed a number of fields. Napier was educated at St Andrews University although he seems to have left without obtaining a degree. He then studied in Europe.

JOHN NAPIER John Napier (lê-se e escreve-se, em geral, Neper) (1550-1617) introduziu o cálculo logarítmico em 1614. John Napier foi um lorde escocês, homem muito culto e conhecedor das matemáticas da época que se envolveu na procura de um sistema que facilitasse a multiplicação de senos, mais tarde estendido a quaisquer números. Esse trabalho estendeu-se por mais de vinte anos e levou à publicação de um livro em 1614, que revolucionou a Matemática da época. A sua obra "Descrição da maravilhosa regra dos logaritmos" causou grande surpresa e entusiasmo porque se tratava de técnicas simplificadoras de resolução de problemas de cálculo numérico, problemas estes relacionados com o desenvolvimento do comércio e da banca e do progresso da Navegação e Astronomia. "A invenção dos logaritmos surgiu no mundo como um relâmpago. Nenhum trabalho prévio anunciava ou fazia prever a sua chegada. Surge isolada e abruptamente no pensamento humano sem que se possa considerar consequência de obras ou de pesquisas anteriores" . Citação de Lord Moulton O sistema logaritmico aplicou-se inicialmente à trigonometria, necessária à navegação e às observações astronómicas, mas foi estendido ao cálculo corrente.
