Mirifici Logarithmorum Canonis Constructio est opus magnum Ioannis Napier, mathematici Scoti, quod anno 1620 editum est. In hoc libro, Napier systema logarithmicum primum descripsit, quod ad calculum arithmeticae et trigonometriae usui erat. Canonis constructio Napieriani logarithmorum mirifica est, quia idem numerus ad diversas quantitates pertinere potest. Hoc opus mathematicum est praecipue utile in scientiis physicae, astronomiae, et navigationis.This Book Is In Latin.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.

John Napier published his treatise on the discovery of logarithms in 1614. It was written in Latin, the scholarly language of his day, under the title Mirifici Logarithmorum Canonis Descriptio. The importance of the work was quickly perceived and an English language translation by Edward Wright followed two years later, with the title A Description of the Admirable Table of Logarithmes. A further English edition followed in 1618. It is said that this book freed the world from a logjam of calculations. John Napier spent more than twenty years working alone on his system of logarithms, during a time when the multiplication and division of large numbers, as well as the finding of square roots, was considered to be extremely difficult. Because of his discovery of logarithms, these tedious mathematical operations could be replaced by the much easier processes of simple addition, subtraction and division by two. Never again would astronomers, architects, merchants and navigators become bogged down with calculations that were simply too difficult or time consuming to carry out. Seeking a name for his discovery, Napier turned to Greek, coining the word Logarithm from logos (Greek for ratio or reckoning) and arithmos (Greek for number). Johannes Kepler, the imperial mathematician and astronomer at Prague, was one of the first to realize the enormous importance of Naperian logarithms. Initially indifferent, his attitude was quickly changed to one of great enthusiasm when he saw that tables of logarithms could considerably ease the burden of difficult astronomical calculations. The French mathematician and astronomer Pierre Simon Laplace said that logarithms, '...by shortening the labours, doubled the life of the astronomer.' At a congress held in Edinburgh to celebrate the 300th anniversary of the publication of this book, it was remarked that '...no previous work had led up to it; nothing had foreshadowed it or heralded its arrival. It stands isolated, breaking upon human thought abruptly, without borrowing from the works of other intellects or following known lines of mathematical thought.' Thus has posterity judged the worth of John Napier, Baron of Merchiston, and his logarithms.

Intended for all readers--including magicians, detectives, musicians, orthopedic surgeons, and anthropologists--this book offers a thorough account of that most intriguing and most human of appendages: the hand. In this illustrated work, John Napier explores a wide range of absorbing subjects such as fingerprints, handedness, gestures, fossil remains, and the making and using of tools.

In Rajasthan, India, a caste of musicians and mendicants, the Nath-Jogis, sing stories of kings who renounce their thrones to become wandering mendicants. They also sing of a god, Mahadeva, Shiva, who must abandon his world-renouncing life and marry, thus establishing the very caste that tells his story. This is the first detailed ethnomusicological study of the music of this caste, examining how the existential questions of the sung stories--of the conflict between loyalty to families or communities and the transcending desire to renounce the material world--are articulated in musical performances in which the caste's own ethnography is inscribed. Discussing the relationship between the performed repertoire and the caste's identity, the contexts of performance and ways in which familiar stories are effectively retold, the book offers a transcription, translation and musical and ethnographic analysis of one performance, by Kishori Nath, and shows how the questions the performances project are not merely speculative acts of self-identification but also challenges to audiences to consider their own responses.
