In this intriguing book G.J. Whitrow traces the evolution of our general awareness of time and its significance from the dawn of history to the present day. His absorbing study ranges from Ancient Egypt and Persia, Greece, and Israel, to the Islamic world, India and China, and Europe andAmerica, showing the different ways time has been perceived by various civilizations.

Time is the crucial ingredient in history, and yet historians rarely talk about time as such. These essays offer new insight into the development of modern conceptions of time, from the Christian dating system (BC/AD or BCE/CE) to the idea of “modernity” as a new epoch in human history. Are the Gregorian calendar, world standard time, and modernity itself simply impositions of Western superiority? How did the idea of stages of history culminating in the modern period arise? Is time really accelerating? Can we—should we—try to move to a new chronological framework, one that reaches back to the origins of humans and forward away or beyond modernity? These questions go to the heart of what history means for us today. Time is now on the agenda.

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.

What is time? When did we first use it? Does it always work? How do animals tell time? A fun and fascinating look at time from the first calendars and clocks to the digital watches and precise time-keeping methods of today.

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.

Our critically acclaimed smash hit Cartographies of Time is now available in paperback. In this first comprehensive history of graphic representations of time, authors Daniel Rosenberg and Anthony Grafton have crafted a lively history featuring fanciful characters and unexpected twists and turns. From medieval manuscripts to websites, Cartographies of Time features a wide variety of timelines that in their own unique ways, curving, crossing, branching, defy conventional thinking about the form. A fifty-four-foot-long timeline from 1753 is mounted on a scroll and encased in a protective box. Another timeline uses the different parts of the human body to show the genealogies of Jesus Christ and the rulers of Saxony. Ladders created by missionaries in eighteenth-century Oregon illustrate Bible stories in a vertical format to convert Native Americans. Also included is the April 1912 Marconi North Atlantic Communication chart, which tracked ships, including the Titanic, at points in time rather than by their geographic location, alongside little-known works by famous figures, including a historical chronology by the mapmaker Gerardus Mercator and a chronological board game patented by Mark Twain. Presented in a lavishly illustrated edition, Cartographies of Time is a revelation to anyone interested in the role visual forms have played in our evolving conception of history

The quest to pinpoint the age of the Earth is nearly as old as humanity itself. For most of history, people trusted mythology or religion to provide the answer, even though nature abounds with clues to the past of the Earth and the stars. In A Natural History of Time, geophysicist Pascal Richet tells the fascinating story of how scientists and philosophers examined those clues and from them built a chronological scale that has made it possible to reconstruct the history of nature itself. Richet begins his story with mythological traditions, which were heavily influenced by the seasons and almost uniformly viewed time cyclically. The linear history promulgated by Judaism, with its story of creation, was an exception, and it was that tradition that drove early Christian attempts to date the Earth. For instance, in 169 CE, the bishop of Antioch, for instance declared that the world had been in existence for “5,698 years and the odd months and days.” Until the mid-eighteenth century, such natural timescales derived from biblical chronologies prevailed, but, Richet demonstrates, with the Scientific Revolution geological and astronomical evidence for much longer timescales began to accumulate. Fossils and the developing science of geology provided compelling evidence for periods of millions and millions of years—a scale that even scientists had difficulty grasping. By the end of the twentieth century, new tools such as radiometric dating had demonstrated that the solar system is four and a half billion years old, and the universe itself about twice that, though controversial questions remain. The quest for time is a story of ingenuity and determination, and like a geologist, Pascal Richet carefully peels back the strata of that history, giving us a chance to marvel at each layer and truly appreciate how far our knowledge—and our planet—have come.
