The subtitle here tells the reader exactly what the book is about; what it doesn't say is how much fun it is to read. The Greek astronomers could measure latitude as early as the third century b.c., but more than 2,000 years passed before the development of a reliable method for measuring longitude. Former New York Times reporter Sobel (coauthor, Arthritis: What Works, 1989, etc.) sets the stage by recounting the difficulties early navigators had in determining their exact longitude. After the loss of many ships and human lives as a result of navigational errors, in 1714 Parliament offered a rich prize for a practical way to measure longitude at sea. British astronomers saw a solution in the stars, by making sufficiently accurate measurements of lunar positions and comparing them to positions calculated for a known reference point. But the calculations could take hours and were tricky even in the best of circumstances; one future astronomer royal, under pressure, botched a measurement of the longitude of Barbados. Enter John Harrison, an apparently self-taught English clockmaker. Over a period of 40 years, he developed four increasingly precise chronometers capable of holding accurate time over a long, rough sea voyage. Comparing the chronometer's time to local sun time, a navigator could measure longitude with high precision in short order. Despite fierce opposition from astronomers (who scorned a "mere mechanic"), Harrison's clocks were enthusiastically endorsed by every mariner who put them to the test (including such luminaries as Cook and Bligh). With the support of King George III, the clockmaker eventually prevailed and won the prize. Sobel tells his story (and the larger history of the search for longitude) clearly, entertainingly, and with a fine sense of the era in which it took place. Breezily written and full of fascinating characters and facts, here's a science book as enjoyable as any novel.

In the same format as his Newbery Honor title The Great Fire (1995), Murphy brings the blizzard of 1888 to life. He shows how military weather-monitoring practices, housing and employment conditions, and politics regarding waste management, transportation monopolies, and utilities regulation, all contributed to—and were subsequently affected by—the disaster. He does so through an appealing narrative, making use of first-hand accounts whose sources he describes in his notes at the end (though, disappointingly he cites nothing directly in the text). The wealth of quotable material made available through the letters of members of “the Society of Blizzard Men and Blizzard Ladies” and other sources help to make the story vivid. Many drawings and photographs (some of the blizzard, but most of related scenes) illustrate the text. These large reproductions are all in a sepia-tone that matches the color of the typeface—an effect that feels over-the-top, but doesn’t detract significantly from the power of the story. Murphy’s ability to pull in details that lend context allows him to tell this story of a place in time through the lens of a single, dramatic episode that will engage readers. This is skillfully done: humorous, jaw-dropping, thought-provoking, and chilling. (index) (Nonfiction. 9-14)

The author of The Snake Scientist (not reviewed) takes the reader along on another adventure, this time to the Bay of Bengal, between India and Bangladesh to the Sundarbans Tiger Preserve in search of man-eating tigers. Beware, he cautions, “Your study subject might be trying to eat you!” The first-person narrative is full of helpful warnings: watch out for the estuarine crocodiles, “the most deadly crocodiles in the world” and the nine different kinds of dangerous sharks, and the poisonous sea snakes, more deadly than the cobra. Interspersed are stories of the people who live in and around the tiger preserve, information on the ecology of the mangrove swamp, myths and legends, and true life accounts of man-eating tigers. (Fortunately, these tigers don’t eat women or children.) The author is clearly on the side of the tigers as she states: “Even if you added up all the people that sick tigers were forced to eat, you wouldn’t get close to the number of tigers killed by people.” She introduces ideas as to why Sundarbans tigers eat so many people, including the theory, “When they attack people, perhaps they are trying to protect the land that they own. And maybe, as the ancient legend says, the tiger really is watching over the forest—for everyone’s benefit.” There are color photographs on every page, showing the landscape, people, and a variety of animals encountered, though glimpses of the tigers are fleeting. The author concludes with some statistics on tigers, information on organizations working to protect them, and a brief bibliography and index. The dramatic cover photo of the tiger will attract readers, and the lively prose will keep them engaged. An appealing science adventure. (Nonfiction. 9-12)
