The Longitude Discovered By The Eclipses Occultations And Conjunctions Of Jupiter S Planets

Simply to say that this is a collection of essays in honor of the late Wolfgang Yourgrau (1908-1979) is to explain, at least for-the obviously many-"insiders," the unusually wide-ranging title of the present volume. In a Foreword to the Proceedings of the First International Colloquium (focusing on logic, physical reality, and history), held at the University of Denver in May of 1966 under their leadership, Wolfgang Y ourgrau and Allen Breck wrote, in an oblique reference to C. P. Snow: "Indeed there are not two or three or four cultures: there is only one culture; our generation has lost its awareness of this . . . . Historians, logicians, physicists-all are banded in one common enterprise, namely in their des ire to weave an enlightened fabric of human knowledge. " Augment, if you will, the foregoing categories of scholars with biologists, philos ophers, cosmologists, and theologians-all of whom, in addition to historians, Wolf gang Yourgrau, by dint of his inextinguishable enthusiasm and charismatic qualities, assembled in Denver for the Second and Third International Colloquia (in 1967 and 1974, respectively)-and a few other besides, and one arrives at a statement of the credo wh ich Y ourgrau not only professed, but consistently exemplified throughout his adult life.

Why make a joke out of a niche and complex scientific problem? That is the question at the heart of this book, which unearths the rich and surprising history of trying to find longitude at sea in the eighteenth century. Not simply a history on water, this is the story of longitude on paper, of the discussions, satires, diagrams, engravings, novels, plays, poems and social anxieties that shaped how people understood longitude in William Hogarth’s London. We start from a figure in one of Hogarth’s prints – a lunatic incarcerated in the madhouse of A Rake’s Progress in 1735 – to unpick the visual, mental and social concerns which entwined around the national concern to find a solution to longitude. Why does longitude appear in novels, smutty stories, political critiques, copyright cases, religious tracts and dictionaries as much as in government papers? This sheds new light on the first government scientific funding body – the Board of Longitude – established to administer vast reward money for anyone who found a means of accurately measuring longitude at sea. Meet the cast of characters involved in the search for longitude, from famous novelists and artists to almost unknown pamphleteers and inventors, and see how their interactions informed the fate of longitude’s most famous pursuer, the clockmaker John Harrison.
