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. The scientific establishment of Europe-from Galileo to Sir Isaac Newton-had mapped the heavens in both hemispheres in its certain pursuit of a celestial answer. In stark contrast, one man, John Harrison, 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.

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.
