One of Smithsonian Magazine's Ten Best History Books of 2021 A captivating, surprising history of timekeeping and how it has shaped our world. For thousands of years, people of all cultures have made and used clocks, from the city sundials of ancient Rome to the medieval water clocks of imperial China, hourglasses fomenting revolution in the Middle Ages, the Stock Exchange clock of Amsterdam in 1611, Enlightenment observatories in India, and the high-precision clocks circling the Earth on a fleet of GPS satellites that have been launched since 1978. Clocks have helped us navigate the world and build empires, and have even taken us to the brink of destruction. Elites have used them to wield power, make money, govern citizens, and control lives—and sometimes the people have used them to fight back. Through the stories of twelve clocks, About Time brings pivotal moments from the past vividly to life. Historian and lifelong clock enthusiast David Rooney takes us from the unveiling of al-Jazari’s castle clock in 1206, in present-day Turkey; to the Cape of Good Hope observatory at the southern tip of Africa, where nineteenth-century British government astronomers moved the gears of empire with a time ball and a gun; to the burial of a plutonium clock now sealed beneath a public park in Osaka, where it will keep time for 5,000 years. Rooney shows, through these artifacts, how time has been imagined, politicized, and weaponized over the centuries—and how it might bring peace. Ultimately, he writes, the technical history of horology is only the start of the story. A history of clocks is a history of civilization.
'An utterly dazzling book, the best piece of history I have read for a long time' Jerry Brotton, author of A History of the World in Twelve Maps 'Not merely an horologist's delight, but an ingenious meditation on the nature and symbolism of time-keeping itself' Richard Holmes The measurement of time has always been essential to human civilization, from early Roman sundials to the advent of GPS. But while we have one eye on the time every day, are we aware of the power clocks have given governments, military leaders and business owners, and how they have shaped our lives and our world? In this spectacularly far-reaching book, David Rooney narrates a history of timekeeping and civilization in twelve concise chapters. Over their course, we meet the most epochal inventions in horological history, from medieval water clocks to Renaissance hourglasses, and from stock-exchange timestamps to satellites in Earth's orbit. We discover how clocks have helped people navigate the globe and build empires, but also, on occasion, taken us to the brink of destruction. This is the story of time, and the story of time is the story of us.
Publisher Description
2022 NATIONAL INDIE EXCELLENCE AWARDS WINNER — HISTORY: GENERAL ". . . inherently interesting, unique, and highly recommended addition to personal, professional, community, college, and academic library Physics of Time & Scientific Measurement history collections, and supplemental curriculum studies lists.” —Midwest Book Review "A wonderful look into understanding and recording time, Orzel’s latest is appropriate for all readers who are curious about those ticks and tocks that mark nearly every aspect of our lives." —Booklist “A thorough, enjoyable exploration of the history and science behind measuring time.” —Foreword Reviews It’s all a matter of time—literally. From the movements of the spheres to the slipperiness of relativity, the story of science unfolds through the fascinating history of humanity’s efforts to keep time. Our modern lives are ruled by clocks and watches, smartphone apps and calendar programs. While our gadgets may be new, however, the drive to measure and master time is anything but—and in A Brief History of Timekeeping, Chad Orzel traces the path from Stonehenge to your smartphone. Predating written language and marching on through human history, the desire for ever-better timekeeping has spurred technological innovation and sparked theories that radically reshaped our understanding of the universe and our place in it. Orzel, a physicist and the bestselling author of Breakfast with Einstein and How to Teach Quantum Physics to Your Dog continues his tradition of demystifying thorny scientific concepts by using the clocks and calendars central to our everyday activities as a jumping-off point to explore the science underlying the ways we keep track of our time. Ancient solstice markers (which still work perfectly 5,000 years later) depend on the basic astrophysics of our solar system; mechanical clocks owe their development to Newtonian physics; and the ultra-precise atomic timekeeping that enables GPS hinges on the predictable oddities of quantum mechanics. Along the way, Orzel visits the delicate negotiations involved in Gregorian calendar reform, the intricate and entirely unique system employed by the Maya, and how the problem of synchronizing clocks at different locations ultimately required us to abandon the idea of time as an absolute and universal quantity. Sharp and engaging, A Brief History of Timekeeping is a story not just about the science of sundials, sandglasses, and mechanical clocks, but also the politics of calendars and time zones, the philosophy of measurement, and the nature of space and time itself. For those interested in science, technology, or history, or anyone who’s ever wondered about the instruments that divide our days into moments: the time you spend reading this book may fly, and it is certain to be well spent.

A New York Times Bestseller “Maps allow the armchair traveler to roam the world, the diplomat to argue his points, the ruler to administer his country, the warrior to plan his campaigns and the propagandist to boost his cause… rich and beautiful.” – Wall Street Journal Throughout history, maps have been fundamental in shaping our view of the world, and our place in it. But far from being purely scientific objects, maps of the world are unavoidably ideological and subjective, intimately bound up with the systems of power and authority of particular times and places. Mapmakers do not simply represent the world, they construct it out of the ideas of their age. In this scintillating book, Jerry Brotton examines the significance of 12 maps - from the almost mystical representations of ancient history to the satellite-derived imagery of today. He vividly recreates the environments and circumstances in which each of the maps was made, showing how each conveys a highly individual view of the world. Brotton shows how each of his maps both influenced and reflected contemporary events and how, by considering it in all its nuances and omissions, we can better understand the world that produced it. Although the way we map our surroundings is more precise than ever before, Brotton argues that maps today are no more definitive or objective than they have ever been. Readers of this beautifully illustrated and masterfully argued book will never look at a map in quite the same way again. “A fascinating and panoramic new history of the cartographer’s art.” – The Guardian “The intellectual background to these images is conveyed with beguiling erudition…. There is nothing more subversive than a map.” – The Spectator “A mesmerizing and beautifully illustrated book.” —The Telegraph
Until the nineteenth century all time was local time. On foot or on horseback, it was impossible to travel fast enough to care that noon was a few minutes earlier or later from one town to the next. The invention of railways and telegraphs, however, created a newly interconnected world where suddenly the time differences between cities mattered. The Clocks Are Telling Lies is an exploration of why we tell time the way we do, demonstrating that organizing a new global time system was no simple task. Standard time, envisioned by railway engineers such as Sandford Fleming, clashed with universal time, promoted by astronomers. When both sides met in 1884 at the International Meridian Conference in Washington, DC, to debate the best way to organize time, disagreement abounded. If scientific and engineering experts could not agree, how would the public? Following some of the key players in the debate, Scott Johnston reveals how people dealt with the contradictions in global timekeeping in surprising ways – from zealots like Charles Piazzi Smyth, who campaigned for the Great Pyramid to serve as the prime meridian, to Maria Belville, who sold the time door to door in Victorian London, to Moraviantown and other Indigenous communities that used timekeeping to fight for autonomy. Drawing from a wide range of primary sources, The Clocks Are Telling Lies offers a thought-provoking narrative that centres people and politics, rather than technology, in the vibrant story of global time telling.
The history of the clock opens a window on how different cultures have viewed time and on Europe's path to industrialization.
