Reseña del editor
"How we measure time-both when and how long-is the subject of the many experiments in this small, lively, information-packed volume....For each experiment, there is a brief statement of principle, then four small sections: what you need, what to do, what happens, and why....The focus is on basic discoveries and applied science, from constructing a perpetual calendar or an hourglass to telling time by the stars....There are also fascinating facts that make you think about what you take for granted (Why do clocks count to 12 and not 24?)...style is clear and informal, with a full glossary..."--I>Booklist. 96 pages, 95 b/w illus., 5 3/8 x 8 1/4.
