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.

It comes as no surprise that, as a kid, Jeopardy! legend Ken Jennings slept with a bulky Hammond world atlas by his pillow every night. Maphead recounts his lifelong love affair with geography and explores why maps have always been so fascinating to him and to fellow enthusiasts everywhere. Jennings takes readers on a world tour of geogeeks from the London Map Fair to the bowels of the Library of Congress, from the prepubescent geniuses at the National Geographic Bee to the computer programmers at Google Earth. Each chapter delves into a different aspect of map culture: highpointing, geocaching, road atlas rallying, even the “unreal estate” charted on the maps of fiction and fantasy. He also considers the ways in which cartography has shaped our history, suggesting that the impulse to make and read maps is as relevant today as it has ever been. From the “Here be dragons” parchment maps of the Age of Discovery to the spinning globes of grade school to the postmodern revolution of digital maps and GPS, Maphead is filled with intriguing details, engaging anecdotes, and enlightening analysis. If you’re an inveterate map lover yourself—or even if you’re among the cartographically clueless who can get lost in a supermarket—let Ken Jennings be your guide to the strange world of mapheads.
