John Napier and the Invention of Logarithms, 1614

A quiet revolution began in 1614. In the hands of John Napier, multiplication shrank to addition and the modern world of computation took shape. Numbers suddenly became much easier. In this historical mathematics lecture, E. W. Hobson reconstructs the invention of logarithms with brisk clarity and humane curiosity, setting Napier's work in seventeenth century Scotland and in the wider 1614 scientific revolution. The focus is not on abstruse symbolism but on purpose: why a laird and scholar pursued new calculation methods, how napierian logarithms history grew from practical needs, and what early logarithm tables meant for astronomers, navigators, and anyone wrestling with large figures. Alongside a succinct John Napier biography, Hobson traces the intellectual leap that turned tedious arithmetic into a tool of speed, accuracy, and confidence. Hobson bridges schoolroom and workshop, showing why logarithms mattered long before electronic machines, and why Napier's insight still shapes the way we calculate today quietly. As a classic lecture reprint presented as a public domain facsimile, this edition offers a compact, authoritative doorway into mathematics as cultural history. It serves math history students seeking a narrative they can hold, and a reference for educators who want context behind formulas. Collectors of foundational scientific writing will value its period voice and its glimpse of the moment logarithms entered common practice. Republished by Alpha Editions in a careful modern edition, this volume preserves the spirit of the original while making it effortless to enjoy today -- a heritage title prepared for readers and collectors alike.
