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.

“I was in an accident. I got out. I'm safe now.” An alternate Victorian world controlled by clock towers, where a damaged clock can fracture time—and a destroyed one can stop it completely. A prodigy mechanic who can repair not only clockwork, but time itself, determined to rescue his father from a Stopped town. A series of mysterious bombings that could jeopardize all of England. A romance that will shake the very foundations of time. The first book in a dazzling new steampunk-fantasy trilogy, Timekeeper introduces a magical world of mythology and innovation that readers will never want to leave.

This first comprehensive, scholarly history of timekeeping in America studies the transition from local to national timekeeping, a process that led to Standard Time—the worldwide system of timekeeping by which we all live. The book describes the contributions of the railroad industry, university astronomers, clockmakers, and civil and electrical engineers.

Not so long ago we timed our lives by the movement of the sun. These days our time arrives atomically and insistently, and our lives are propelled by the notion that we will never have enough of the one thing we crave the most. How have we come to be dominated by something so arbitrary?The compelling stories in this book explore our obsessions with time. An Englishman arrives back from Calcutta but refuses to adjust his watch. Beethoven has his symphonic wishes ignored. A moment of war is frozen forever. The timetable arrives by steam train. A woman designs a ten-hour clock and reinvents the calendar. Roger Bannister becomes stuck in the same four minutes forever. A British watchmaker competes with mighty Switzerland. And a prince attempts to stop time in its tracks.Timekeepers is a vivid exploration of the ways we have perceived, contained and saved time over the last 250 years, narrated in the highly inventive and entertaining style that bestselling author Simon Garfield is fast making his own. As managing time becomes the greatest challenge we face in our lives, this multi-layered history helps us tackle it in a sparkling new light.

This book provides a comprehensive, systematic description of modern timekeeping and its specializations. Introductory chapters discuss the concept of time and its definition, then briefly look at pre-Atomic Era timekeeping to set the stage for the introduction of the atomic clock. Subsequent chapters focus on concepts such as frequency stability and measurement uncertainty, as well as computer network time-synchronization protocols including Network Time Protocol (NTP) and Precise Time Protocol (PTP). The book then delves into the nuts and bolts of the Global Navigation Satellite Systems (GNSS), Two-Way Satellite Time and Frequency Transfer, and Optical Time and Frequency Transfer. Timescale theory is then described as a way to combine clock data, and the algorithms and procedures used to generate Coordinated Universal Time (UTC) are given. Finally, there is a look at modern applications of timekeeping and time transfer. Featuring a glossary of all key terms, this book is highly recommended for trained or incoming physicists, engineers, or mathematicians working, for example, in manufacturing or timing laboratories. Additionally, it is suitable for use in introductory university courses dealing with the subject of timekeeping.

FROM THE MASTER STORYTELLER WHOSE BOOKS HAVE TOUCHED THE HEARTS OF OVER 40 MILLION READERS 'Mitch Albom sees the magical in the ordinary' Cecilia Ahern __________ Banished for centuries, as punishment for trying to measure time, the inventor of the world's first clock is finally granted his freedom, along with a mission: a chance to redeem himself by teaching two people the true meaning of time.
