Book Description
The dramatic human story of an epic scientific quest and of one man's forty-year obsession to find a solution to the thorniest scientific dilemma of the day--"the longitude problem." Anyone alive in the eighteenth century would have known that "the longitude problem" was the thorniest scientific dilemma of the day-and had been for centuries. Lacking the ability to measure their longitude, sailors throughout the great ages of exploration had been literally lost at sea as soon as they lost sight of land. Thousands of lives and the increasing fortunes of nations hung on a resolution. One man, John Harrison, in complete opposition to the scientific community, dared to imagine a mechanical solution-a clock that would keep precise time at sea, something no clock had ever been able to do on land. Longitude is the dramatic human story of an epic scientific quest and of Harrison's forty-year obsession with building his perfect timekeeper, known today as the chronometer. Full of heroism and chicanery, it is also a fascinating brief history of astronomy, navigation, and clockmaking, and opens a new window on our world.

Book Description
Official publication of the National Maritime Museum's exhibition "Ships, Clocks and Stars: The Quest for Longitude". 300 years ago, amidst growing frustration from the naval community and pressure from the increasing importance of international trade, the British government passed the 1714 Longitude Act. It was an attempt to solve one of the most pressing problems of the age: how to determine a ship's longitude (east-west position) at sea. With life-changing rewards on offer, the challenge captured the imaginations and talents of astronomers, skilled craftsmen, politicians, seamen and satirists. This beautifully illustrated book is a detailed account of these stories, and how the longitude problem was solved. Highlights of the book include: * Foreword by the fifteenth Astronomer Royal, Martin Rees. * Specially commissioned photographs of the National Maritime Museum's collection. * A new description of the collaborations and conflicts in a tale of technical creativity, scientific innovation and hard commercialism. From the same publisher as Dava Sobel's Longitude, Finding Longitude tells a new story of one of the great achievements of the Georgian age, and how it changed our understanding of the world.

Book Description
A tale of eighteenth-century invention and competition, commerce and conflict, this is a lively, illustrated, and accurate chronicle of the search to solve “the longitude problem,” the question of how to determine a ship’s position at sea—and one that changed the history of mankind. Ships, Clocks, and Stars brings into focus one of our greatest scientific stories: the search to accurately measure a ship’s position at sea. The incredible, illustrated volume reveals why longitude mattered to seafaring nations, illuminates the various solutions that were proposed and tested, and explores the invention that revolutionized human history and the man behind it, John Harrison. Here, too, are the voyages of Captain Cook that put these revolutionary navigational methods to the test. Filled with astronomers, inventors, politicians, seamen, and satirists, Ships, Clocks, and Stars explores the scientific, political, and commercial battles of the age, as well as the sailors, ships, and voyages that made it legend—from Matthew Flinders and George Vancouver to the voyages of the Bounty and the Beagle. Featuring more than 150 photographs specially commissioned from Britain’s National Maritime Museum, this evocative, detailed, and thoroughly fascinating history brings this age of exploration and enlightenment vividly to life.

Book Description
Long before GPS, Google Earth, and global transit, humans traveled vast distances using only environmental clues and simple instruments. John Huth asks what is lost when modern technology substitutes for our innate capacity to find our way. Encyclopedic in breadth, weaving together astronomy, meteorology, oceanography, and ethnography, The Lost Art of Finding Our Way puts us in the shoes, ships, and sleds of early navigators for whom paying close attention to the environment around them was, quite literally, a matter of life and death. Haunted by the fate of two young kayakers lost in a fog bank off Nantucket, Huth shows us how to navigate using natural phenomena—the way the Vikings used the sunstone to detect polarization of sunlight, and Arab traders learned to sail into the wind, and Pacific Islanders used underwater lightning and “read” waves to guide their explorations. Huth reminds us that we are all navigators capable of learning techniques ranging from the simplest to the most sophisticated skills of direction-finding. Even today, careful observation of the sun and moon, tides and ocean currents, weather and atmospheric effects can be all we need to find our way. Lavishly illustrated with nearly 200 specially prepared drawings, Huth’s compelling account of the cultures of navigation will engross readers in a narrative that is part scientific treatise, part personal travelogue, and part vivid re-creation of navigational history. Seeing through the eyes of past voyagers, we bring our own world into sharper view.

Book Description
Since its launch in 1987, the History of Cartography series has garnered critical acclaim and sparked a new generation of interdisciplinary scholarship. Cartography in the European Enlightenment, the highly anticipated fourth volume, offers a comprehensive overview of the cartographic practices of Europeans, Russians, and the Ottomans, both at home and in overseas territories, from 1650 to 1800. The social and intellectual changes that swept Enlightenment Europe also transformed many of its mapmaking practices. A new emphasis on geometric principles gave rise to improved tools for measuring and mapping the world, even as large-scale cartographic projects became possible under the aegis of powerful states. Yet older mapping practices persisted: Enlightenment cartography encompassed a wide variety of processes for making, circulating, and using maps of different types. The volume’s more than four hundred encyclopedic articles explore the era’s mapping, covering topics both detailed—such as geodetic surveying, thematic mapping, and map collecting—and broad, such as women and cartography, cartography and the economy, and the art and design of maps. Copious bibliographical references and nearly one thousand full-color illustrations complement the detailed entries.

Book Description
Explores the links between science and empire in the 19th cent\ury, focusing on the mutual interactions of British imperialism and geophysical empiricism. The 19th century was a time when science was becoming global, in part due to European colonial and imperial expansion. Colonies became not just propagation points for European science, but also collection points for geophysical investigations. These “colonial observatories” influenced the type of science that could be done. Comparing the development of British and American geomagnetic research during this period shows the dependency between the two influences. Both the scientific theories and the geopolitical realities played a role in creating the tool for studying global science still in use today.

Book Description
This comprehensive volume explores the intricate, mutually dependent relationship between science and exploration—how each has repeatedly built on the discoveries of the other and, in the process, opened new frontiers. A simple question: Which came first, advances in navigation or successful voyages of discovery? A complicated answer: Both and neither. For more than four centuries, scientists and explorers have worked together—sometimes intentionally and sometimes not—in an ongoing, symbiotic partnership. When early explorers brought back exotic flora and fauna from newly discovered lands, scientists were able to challenge ancient authorities for the first time. As a result, scientists not only invented new navigational tools to encourage exploration, but also created a new approach to studying nature, in which observations were more important than reason and authority. The story of the relationship between science and exploration, analyzed here for the first time, is nothing less than the history of modern science and the expanding human universe.
