VOYA—“ . . . With a friendly, relaxed writing style, Formichelli and Martin cover the history of timekeeping beginning with the first humans, who measured time simply by watching the seasons, and ending with the invention of astoundingly precise atomic and optical clocks. The book covers the development of the first calendars, interesting clocks throughout the ages, the world’s time zones, and daylight savings time. Intriguing science experiments demonstrate various concepts of time and give the reader instructions to build several timekeeping mechanisms. The authors also include a time line of major developments in the science of timekeeping and provide lists of websites and famous monuments involving time. To be able to address a topic as complex as that of time in such a concise and interesting manner is truly impressive . . . this book is generally readable, enjoyable, and extremely informative.”
Booklist—“ . . . Fifteen versatile and hands-on projects range from very simple exercises that can be completed in moments, such as reading seasons from a shadow, to more sophisticated temporal experiments like making your own incense clock. These projects could be used as a fun diversion on a rainy afternoon at home or as the crux of an elementary science lesson.”
