Book excerpt: 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.

Download or read book Rubidium Atomic Clock The Workhorse Of Satellite Navigation written by G M Saxena and published by World Scientific. This book was released on 2020-03-05 with total page 317 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Rubidium atomic clock (Rb) is the workhorse of the satellite navigation systems of which GPS is now a household name. With just the tap of a few keys, drivers and navigators all over the world are able to reach their destination effortlessly with high precision. People are now curious to know what makes this possible. Hence, the need to explain in simplistic terms the Rb atomic clocks that are onboard these satellite navigation systems because no good satellite navigation system is possible without such clocks.But why only Rb atomic clocks when far better and exotic atomic clocks are available? The reasons are as simple as that they are slim, low in weight, easy to build inexpensively. They are also used in numerous military applications such as secure communications, electronic warfare, command and control, telemetry and navigation. Besides, they are used in the measurements of the variation in fine-structure constant, test of relativity, precise spectroscopy and scientific research.This book details the history of time keeping and the chronological development of the Rb atomic clocks, with special focus on the physics Package that accounts for the actual performance of the clock. Researchers and industrialists will find that producing such clocks is relatively simple and inexpensive.
Download or read book About Time written by David Rooney and published by National Geographic Books. This book was released on 2022-08-09 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Down to the Hour Short Time in the Ancient Mediterranean and Near East written by and published by BRILL. This book was released on 2019-12-02 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Clock time", with all its benefits and anxieties, is often viewed as a "modern" phenomenon, but ancient Mediterranean and Near Eastern cultures also had tools for marking and measuring time within the day and wrestled with challenges of daily time management. This book brings together for the first time perspectives on the interplay between short-term timekeeping technologies and their social contexts in ancient Egypt, Babylon, Greece, and Rome. Its contributions denaturalize modern-day concepts of clocks, hours, and temporal frameworks; describe some of the timekeeping solutions used in antiquity; and illuminate the diverse factors that affected how individuals and communities structured their time.
Download or read book The Science of Time 2016 written by Elisa Felicitas Arias and published by Springer. This book was released on 2017-10-05 with total page 381 pages. Available in PDF, EPUB and Kindle. Book excerpt: The uses of time in astronomy - from pointing telescopes, coordinating and processing observations, predicting ephemerides, cultures, religious practices, history, businesses, determining Earth orientation, analyzing time-series data and in many other ways - represent a broad sample of how time is used throughout human society and in space. Time and its reciprocal, frequency, is the most accurately measurable quantity and often an important path to the frontiers of science. But the future of timekeeping is changing with the development of optical frequency standards and the resulting challenges of distributing time at ever higher precision, with the possibility of timescales based on pulsars, and with the inclusion of higher-order relativistic effects. The definition of the second will likely be changed before the end of this decade, and its realization will increase in accuracy; the definition of the day is no longer obvious. The variability of the Earth's rotation presents challenges of understanding and prediction. In this symposium speakers took a closer look at time in astronomy, other sciences, cultures, and business as a defining element of modern civilization. The symposium aimed to set the stage for future timekeeping standards, infrastructure, and engineering best practices for astronomers and the broader society. At the same time the program was cognizant of the rich history from Harrison's chronometer to today's atomic clocks and pulsar observations. The theoreticians and engineers of time were brought together with the educators and historians of science, enriching the understanding of time among both experts and the public.
Download or read book The Mastery of Time written by Dominique Flechon and published by Rizzoli Publications. This book was released on 2012-01-10 with total page 455 pages. Available in PDF, EPUB and Kindle. Book excerpt: More than a simple chronology, this volume explores the technical resources used to measure time—solar, hydraulic, mechanical, or electrical—just as it explains the key factors behind the major breakthroughs in the science of horology. From ancient astronomical observatories to atomic clocks, instruments for telling time have always been closely linked to the cutting-edge sciences of the day, ranging from medicine and navigation to aeronautics. Inventions in timekeeping have been crucial to the organization of human society and to activities such as farming, industry, and trade. Each new development was based on the needs and accomplishments of its day yet spurred further discoveries. Writing a history of time means viewing human genius through the prism of the steady mastery of a crucial technology. The patient, long-term conquest of accuracy has been the result of successive advances from sundial to wristwatch up to the recent exploits of the heirs to this age-old quest, namely master horologists of the twenty-first century.

Download or read book The Book of Time written by Colin Wilson and published by . This book was released on 1980 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: " We consider that we are constantly aware of the passage of time, and yet we understand next to nothing of its nature. In an instinctive way, we accept time as invariant, immutable, and feel somehow that the foundations of our world are rocking when we are told that the passage of time does indeed vary, depending on the situation of the person measuring that passage. Our surprise is a result of thousands of years of conditioning, during which Man has measured time with ever greater accuracy and hence come increasingly to rely upon its inviolability. The book takes as its subject time and Man's relationship with it. The scope includes many aspects of philosophy, hstory, anthropology, horology and physical science, and it is this multidisciplinary nature which is the source of The Book of Time's unique fascination. Among the topics discussed are the measurements of time, from the earliest crude sundials to the most refined modern atomic clocks, the development of the calendar, the cycle of the seasons, biological clocks and 'bodytime', the measurement of the timescales of the reote past over the thirteen billion years since the Universe was born, and the phenomena that defy all normal rules of common sense and yet are direct manifestations of the real nature of time. 'The Book of Time' is, in addition, full of absorbing sidelights on subjects as diverse at the harmony of the spheres, the reasons why all human beings have approximately the same pulse-rate, the evolution of the clock escapement, and the possibilities of time travel and the paradoxes inherent therein. 'The Book of Time' is by a panel of seven distinguished authors, each of whom has written that section of the book most closely allied to his own field." -- Book Jacket.
