The book focuses closely on the history of navigation and how it is connected to time. If you have ever wondered, ‘Just how did they do that?’ in reference to navigation, this book (and the exhibits) have you covered. Find out where we started, and marvel at how far we’ve come.
This companion to an exhibit of the same name at the Smithsonian National Air and Space Museum is a slim but impressive volume. Johnston, a geographer at the museum, and curators Roger D. Connor (instruments and avionics), Carlene E. Stephens (timekeeping), and Paul E. Ceruzzi (aerospace electronics and computing) explain that there is a definite but often overlooked link between time and place. Understanding how the two are related has been integral to the evolution of navigation. In material that is articulate and flawlessly logical, the authors show, step by step, how developments in marine navigation gave way to air and then space navigation. In turn, developments in space navigation took the practice from a highly specialized, erudite science to an everyday tool. Presented chronologically, the narrative unfolds as the authors explain how the political, economic, scientific, and military ambitions of a variety of countries and peoples built on one another—the 1848 California gold rush had an influence on shipbuilding and the implementation of new sea charts, for example. A feature called “Navigation Gone Wrong” appears occasionally and highlights failed expeditions throughout history, such as Amelia Earhart’s final flight and the destruction of the spacecraft Mariner I. Another occasional feature called “Meet the…” introduces readers to influential figures such as the teacher Philip Van Horn Weems and the clockmaker William Cranch Bond. Discipline-specific terms such as chronometer and astrolabe are defined in-text. The 232 full-color and black-and-white illustrations consist of scores of photos, maps, and drawings. VERDICT Making a complex topic accessible to lay people, this title is a must-have for libraries serving general adult populations.—Jennifer Prince, Buncombe Cty. P.L. Syst., NC
Entertaining and packed with information, this collaborative volume from the National Air and Space Museum and the National Museum of American History covers the history of navigation from the days of the astrolabe to global positioning satellites. The emphasis is on the importance of time in establishing position. From the 16th century, European colonizing nations offered prizes to anyone who could invent a clock that would work at sea. The first section describes these various clocks and the development of the ability to chart a course using longitude, which would enable transoceanic sailing. When humans took to the air, they discovered that they needed more exact equipment to find their way, and during WWII the application of radar pushed navigation into the stratosphere. This in turn led to the developments in timekeeping that allowed even more precise navigation to the moon and beyond. The work closes by addressing current means of navigating via smartphone. Copiously illustrated, this book contains fascinating anecdotes as well as a wide range of technical information to complement the stories of those who strove to improve the means of human exploration.

This handsome, oversize volume covers the history of navigation in sea, air, and space, from the sea voyages of the early Chinese, Egyptians, and Scandinavians through the development of modern GPS techniques. Johnston and his three fellow authors (all, National Air and Space Museum) describe the uses and importance of astrolabes, sextants, and other historic instruments. Timekeeping was also vital to ocean navigation, and the book details the difficulties of inventing clocks that would work and keep accurate time at sea. The advent of flying brought new navigating challenges, and tools such as radio navigation systems were developed. Space flight posed yet greater problems for navigators and demanded more precision than ever before, and also led to innovations that improved navigation on earth. The ability to launch satellites into orbit made possible the Global Positioning System, which is today the basis of almost all mapping applications and devices. Profusely illustrated with photographs, maps, charts, and color drawings, Time and Navigation will be excellent for arousing interest in navigation and its history, and for providing basic facts for student reports and projects.
