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.

Longitude, Dava Sobel's no.1 bestseller, is the elegant biography of the lone genius who solved the greatest scientific problem of his times. With new material from Dava Sobel and William Andrewes, and illustrated with over 200 integrated photographs, The Illustrated Longitude is the essential book for everyone who fell in love with John Harrison's story and wants to know more. Anyone alive in the 18th 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. The scientific establishment throughout Europe -- from Galileo to Sir Isaac Newton -- had mapped the heavens in its certain pursuit of a celestial answer. In stark contrast, one man, John Harrison, dared to imagine a mechanical solution. The Illustrated Longitude is a fascinating history of astronomy, navigation and clockmaking. Lavishly produced with over 200 illustrations, The Illustrated Longitude has much new material to help the reader learn more of John Harrison's extraordinary story an

"After more than a decade of planning, John Higham and his wife September bid their high-tech jobs and suburban lives adieu, packed up their home and set out with two children, ages eight and eleven, to travel around the world. In the course of the next 52 weeks they crossed 24 time zones, visited 28 countries and experienced a lifetime of adventures"--P. [4] of cover.

Description :


"For hundreds of years ships had been sailing to places far and near without really knowing where they were!" Sailors knew how to measure latitude, their location north or south of the equator, but they could not measure longitude, their location east or west of their home port. Because of this, many lives were lost worldwide. The key to solving this problem lay in devising a clock that could keep absolutely accurate time while at sea, unaltered by rough water or weather conditions. With such a timekeeper sailors would be able to know the time back at their home port and calculate the longitude. But no one knew how to design such a clock. John Harrison (1693-1776), an Englishman without any scientific training, worked tirelessly for more than forty years to create a perfect clock. The solution to this problem was so important that an award of 20,000 pounds sterling (equal to several million dollars today) was established by the English Parliament in 1714. Harrison won recognition for his work in 1773. Together with beautifully detailed pictures by Erik Blegvad, Louise Borden's text takes the reader through the drama, disappointments, and successes that filled Harrison's quest to invent the perfect sea clock.

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.

Description :


Before Captain Cook's three voyages, to Europeans the globe was uncertain and dangerous; after, it was comprehensible and ordered. Written as a conceptual field guide to the voyages, Longitude and Empire offers a significant rereading of both the expeditions and modern political philosophy. More than any other work, printed accounts of the voyages marked the shift from early modern to modern ways of looking at the world. The globe was no longer divided between Europeans and savages but populated instead by an almost overwhelming variety of national identities. Cook's voyages took the fragmented and obscure global descriptions available at the time and consolidated them into a single, comprehensive textual vision. Locations became fixed on the map and the people, animals, plants, and artifacts associated with them were identified, collected, understood, and assimilated into a world order. This fascinating account offers a new understanding of Captain Cook's voyages and how they affected the European world view.

Description :


This monograph is the outcome of an American Geophysical Union Chapman Conference on longitude and hemispheric dependence of ionospheric space weather, including the impact of waves propagating from the lower atmosphere. The Chapman Conference was held in Africa as a means of focusing attention on an extensive geographic region where observations are critically needed to address some of the fundamental questions of the physical processes driving the ionosphere locally and globally. The compilation of papers from the conference describes the physics of this system and the mechanisms that control ionospheric space weather in a combination of tutorial-like and focused articles that will be of value to the upper atmosphere scientific community in general and to ongoing global magnetosphere-ionosphere-thermosphere (MIT) modeling efforts in particular. A number of articles from each science theme describe details of the physics behind each phenomenon that help to solve the complexity of the MIT system. Because this volume is an outcome of the research presented at this first space science Chapman Conference held in Africa, it has further provided an opportunity for African scientists to communicate their research results with the international community. In addition, the meeting and this conference volume will greatly enhance the space science education and research interest in the African continent and around the world. Ionospheric Space Weather includes articles from six science themes that were discussed at the Chapman Conference in 2012. These include: Hemispherical dependence of magnetospheric energy injection and the thermosphere-ionosphere response Longitude and hemispheric dependence of storm-enhanced densities (SED) Response of the thermosphere and ionosphere to variability in solar radiation Longitude spatial structure in total electron content and electrodynamics Temporal response to lower-atmosphere disturbances Ionospheric irregularities and scintillation Ionospheric Space Weather: Longitude Dependence and Lower Atmosphere Forcing will be useful to both active researchers and advanced graduate students in the field of physics, geophysics, and engineering, especially those who are keen to acquire a global understanding of ionospheric phenomena, including observational information from all longitude sectors across the globe.
