Much more than a travel narrative 360 Degrees Longitude: One Family’s Journey Around the World is a glimpse at what it means to be a “global citizen”—a progressively changing view of the world as seen through the eyes of an American family of four. After more than a decade of planning, John Higham and his wife September bid their high-tech jobs and suburban lives good-bye, 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. Making their way across the world, the Highams discovered more than just different foods and cultures; they also learned such diverse things as a Chilean mall isn’t the best place to get your ears pierced, and that elephants appreciate flowers just as much as the next person. But most importantly, they learned about each other, and just how much a family can weather if they do it together. 360 Degrees Longitude employs Google’s wildly popular Google Earth as a compliment to the narrative. Using your computer you can spin the digital globe to join the adventure cycling through Europe, feeling the cold stare of a pride of lions in Africa, and breaking down in the Andes. Packed with photos, video and text, the online Google Earth companion adds a dimension not possible with mere paper and ink. Fly over the terrain of the Inca Trail or drill down to see the majesty of the Swiss Alps—without leaving the comfort of your chair.

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.
