Book Description
Travel through time with the maestros as they explore the amazing history of timekeeping! Did you know that there is more than one calendar? While the most commonly used calendar was on the year 2000, the Jewish calendar said it was the year 5760, while the Muslim calendar said 1420 and the Chinese calendar said 4698. Why do these differences exist? How did ancient civilizations keep track of time? When and how were clocks first invented? Find answers to all these questions and more in this incredible trip through history.

Book 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.

Book Description
How do calendars and clocks influence considerations of school effectiveness? From the creation of compulsory education to the future of virtual schooling, Weiss and Brown trace two centuries of school practices, policies and research linking the concept of time with ‘opportunity to learn’. School calendars and clocks are shaped by both the physical and social worlds, and the ‘clock of schooling’ is shown to be one of the ‘great clocks of society’ that helps to frame school effectiveness. School time does not operate in a vacuum, but within curriculum, teaching and learning situations. The phrase ‘chrono-curriculum’ was devised by the authors as a metaphor for exploring issues of school effectiveness within the time dimension. Using American and Canadian sources, stories are created to illustrate four themes about time and school effectiveness. The first three stories utilize access, attendance and testing as criteria associated with these eras of schooling. How will the story read in the fourth era, the digital age, which forces us to a reconsideration of time and its influence on education? Quoting David Berliner in his Foreword: “ this is an opportune time for these authors to bring us insights into the reasons we in North America created our public school systems, and how the chrono-curriculum influences those systems. The authors’ presentation of our educational past provides educators a chance to think anew about how we might do schooling in our own times.”

Book Description
The essays in this volume explore how two domains of human experience and action--religion and technology--are implicated in each other. Contrary to commonsense understandings of both religion (as an "otherworldly" orientation) and technology (as the name for tools, techniques, and expert knowledges oriented to "this" world), the contributors to this volume challenge the grounds on which this division has been erected in the first place. What sorts of things come to light when one allows religion and technology to mingle freely? In an effort to answer that question, Deus in Machina embarks upon an interdisciplinary voyage across diverse traditions and contexts where religion and technology meet: from the design of clocks in medieval Christian Europe, to the healing power of prayer in premodern Buddhist Japan, to 19th-century Spiritualist devices for communicating with the dead, to Islamic debates about kidney dialysis in contemporary Egypt, to the work of disability activists using documentary film to reimagine Jewish kinship, to the representation of Haitian Vodou on the Internet, among other case studies. Combining rich historical and ethnographic detail with extended theoretical reflection, Deus in Machina outlines new directions for the study of religion and/as technology that will resonate across the human sciences, including religious studies, science and technology studies, communication studies, history, anthropology, and philosophy.

Book Description
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.
