Winner of the Runciman Award Winner of the Charles J. Goodwin Award "Tells the story of how the Seleucid Empire revolutionized chronology by picking a Year One and counting from there, rather than starting a new count, as other states did, each time a new monarch was crowned...Fascinating." -Harper's In the aftermath of Alexander the Great's conquests, his successors, the Seleucid kings, ruled a vast territory stretching from Central Asia and Anatolia to the Persian Gulf. In 305 BCE, in a radical move to impose unity and regulate behavior, Seleucus I introduced a linear conception of time. Time would no longer restart with each new monarch. Instead, progressively numbered years-continuous and irreversible-became the de facto measure of historical duration. This new temporality, propagated throughout the empire and identical to the system we use today, changed how people did business, recorded events, and oriented themselves to the larger world. Some rebellious subjects, eager to resurrect their pre-Hellenic past, rejected this new approach and created apocalyptic time frames, predicting the total end of history. In this magisterial work, Paul Kosmin shows how the Seleucid Empire's invention of a new kind of time-and the rebellions against this worldview-had far reaching political and religious consequences, transforming the way we organize our thoughts about the past, present, and future. "Without Paul Kosmin's meticulous investigation of what Seleucus achieved in creating his calendar without end we would never have been able to comprehend the traces of it that appear in late antiquity...A magisterial contribution to this hitherto obscure but clearly important restructuring of time in the ancient Mediterranean world." -G. W. Bowersock, New York Review of Books "With erudition, theoretical sophistication, and meticulous discussion of the sources, Paul Kosmin sheds new light on the meaning of time, memory, and identity in a multicultural setting." -Angelos Chaniotis, author of Age of Conquests

In this encyclopedia, some 200 international scholars in 360 articles explore subjects such as physics, archeostronomy, astronomy, mathematics, time's measurements and divisions, as well as covering other scientific and interdisciplinary areas: biology, economics and political science, horology, history, medicine, geography, geology and telecommunications.

The arrow of time refers to the curious asymmetry that distinguishes the future from the past. Reversing the Arrow of Time argues that there is an intimate link between the symmetries of 'time itself' and time reversal symmetry in physical theories, which has wide-ranging implications for both physics and its philosophy. This link helps to clarify how we can learn about the symmetries of our world; how to understand the relationship between symmetries and what is real, and how to overcome pervasive illusions about the direction of time. Roberts explains the significance of time reversal in a way that intertwines physics and philosophy, to establish what the arrow of time means and how we can come to know it. This book is both mathematically and philosophically rigorous yet remains accessible to advanced undergraduates in physics and philosophy of physics. This title is also available as Open Access on Cambridge Core.

This pack contains a book and CD-ROM. "The Chronology of the Old Testament" has one goal to accomplish: to demonstrate that every chronological statement contained in the Sacred Writ, is consistent with all other chronological statements contained therein. The author carefully and thoroughly investigates the chronological and mathematical facts of the Old Testament, proving them to be accurate and reliable. This biblically sound, scholarly, and easy-to-understand book; will enlighten and astound its readers with solutions and alternatives to many questions Bible scholars have had over the centuries. Were there 66, 70, or 75 'souls' in Egypt when Jacob arrived? Were the Hebrews in Egypt for 430 years, or a shorter length of time? How long did Jacob have to wait before marrying the first of Laban's daughters, and how long did he wait for the second? What year was Christ born? With reliable explanatory text, charts, and diagrams; this book provides a systematic framework of the chronology of the Bible from Genesis through the life of Christ. Wall-sized chronological charts are also included on the CD-ROM.

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.

From the patristic age until the Gregorian calendar reform of 1582, computus -- the science of time reckoning and art of calendar construction -- was a matter of intense concern. Bede's The Reckoning of Time (De temporum ratione) was the first comprehensive treatise on this subject and the model and reference for all subsequent teaching discussion and criticism of the Christian calendar. It is a systematic exposition of the Julian solar calendar and the Paschal table of Dionysius Exiguus, with their related formulae for calculating dates. But it is more than a technical handbook. Bede sets calendar lore within a broad scientific framework and a coherent Christian concept of time, and incorporates themes as diverse as the theory of tides and the doctrine of the millennium.

This translation of the full text of The Reckoning of Time includes an extensive historical introduction and a chapter-by-chapter commentary. It will interest historians of medieval science, theology, and education, Bede scholars and Anglo-Saxonists, liturgists, and Church historians. It will also serve as an accessible introduction to computus itself. Generations of medieval computists nourished their expertise in Bede's orderly presentation; modern scholars in quest of safe passage through this complex terrain can hope for no better guide.

The concern with time permeates Freud's work, from Studies on Hysteria to Analysis Terminable and Interminable, which point out to a network of concepts that indicate Freud's complex theories on temporality. Indeed no other psychoanalytic thinker has put forward such revolutionary vision on the dimensions of time in human existence. This volume brings together some of the most important papers written on the topic by members of the British Psychoanalytical Society. In the richness of the detailed clinical discussions the ways in which patients deal with time and memory are viewed as crucial indications about their internal world and ways of relating to their objects. Disorientation regarding time tends to reflect levels of disruption to internal object relationships, inability to mourn or to experience guilt. Examples from literature and history are considered in order to examine the power of the repetition compulsion - Nachtreglichkeit - as well as how the impossibility of bearing the mental pain can lead to the creation of a timeless world.

Gender in Real Time brings gender into the realm of time. Weston introduces the temporality concept, looking at the ways that gender exists and can be measured in units of time. Her use of time, and the concept of the 'zero' allow us to conceive of a genderless world free of current academic debates surrounding the number of genders in existence.

"Time" is the most common noun in the English language yet philosophers and scientists don't agree about what time actually is or how to define it. Perhaps this is because the brain tells, represents and perceives time in multiple ways. Dean Buonomano investigates the relationship between the brain and time, looking at what time is, why it seems to speed up or slow down and whether our sense that time flows is an illusion. Buonomano presents his theory of how the brain tells time, and illuminates such concepts as free will, consciousness, space-time and relativity from the perspective of a neuroscientist. Drawing on physics, evolutionary biology and philosophy, he reveals that the brain's ultimate purpose may be to predict the future-and thus that your brain is a time machine.

In a unique volume, Contested Futures brings together a group of scholars to examine the relationships between social action and the future. Rather than speculating upon what the future might bring, the volume interrogates the metaphors and practices through which the future is mobilized as an object of present day action and agency. The book shifts the analytical gaze from looking into the future to looking at the future as a sociological phenomenon in its own right. Futures are thus contested in as much as they register differences of interest, time frame or organizational and political form. Contestation is also evident in the ascendancy of certain discourses, languages and metaphors which foreclose some futures whilst facilitating others. But futures are far from being simply linguistic abstractions, and in fact can often be seen to harden into material entrenchment as expectations become scripted into 'path dependency' and 'lock in'. Contested Futures is an invaluable analysis for both academics and policy actors seeking a better understanding of the ubiquity of futures-discourse in the context of today's uncertainties.

In a universe filled by chaos and disorder, one physicist makes the radical argument that the growth of order drives the passage of time -- and shapes the destiny of the universe. Time is among the universe's greatest mysteries. Why, when most laws of physics allow for it to flow forward and backward, does it only go forward? Physicists have long appealed to the second law of thermodynamics, held to predict the increase of disorder in the universe, to explain this. In The Janus Point, physicist Julian Barbour argues that the second law has been misapplied and that the growth of order determines how we experience time. In his view, the big bang becomes the "Janus point," a moment of minimal order from which time could flow, and order increase, in two directions. The Janus Point has remarkable implications: while most physicists predict that the universe will become mired in disorder, Barbour sees the possibility that order -- the stuff of life -- can grow without bound. A major new work of physics, The Janus Point will transform our understanding of the nature of existence.

Originally published in 1926, this book contains a general history of the measurement of time now known as the week. Colson begins with the seven-day cycle devised by the Jews and examines how different theologies gave rise to different names and systems of measurement for each day of the week and how the week eventually became standardised. This book will be of value to anyone with an interest in ancient astronomy and the history of time keeping.

A history of the innovation and effects of the French Republican Calendar. The French Republican Calendar was perhaps the boldest of all the reforms undertaken in Revolutionary France. Introduced in 1793 and used until 1806, the Calendar not only reformed the weeks and months of the year, but decimalisedthe hours of the day and dated the year from the beginning of the French Republic. This book not only provides a history of the calendar, but places it in the context of eighteenth-century time-consciousness, arguing that the French were adept at working within several systems of time-keeping, whether that of the Church, civil society, or the rhythms of the seasons. Developments in time-keeping technology and changes in working patterns challenged early-modern temporalities, and the new calendar can also be viewed as a step on the path toward a more modern conception of time. In this context, the creation of the calendar is viewed not just as an aspect of the broader republican programme of social, political and cultural reform, but as a reflection of a broader interest in time and the culmination of several generations' concern with how society should be policed. Matthew Shaw is a curatorat the British Library, London.

Originally published in 1921, this book provides a concise guide to the Western Calendar. Information is provided on its origin and development, the principles of its construction, the purposes for which it is employed, its deficiencies and the means by which these deficiencies can be amended. The text also contains a list of authorities on the calendar and a table of astronomical data in mean solar time. This book will be of value to anyone with an interest in the Western Calendar and the measurement of time in general.

On April 6, 1922, in Paris, Albert Einstein and Henri Bergson publicly debated the nature of time. Einstein considered Bergson's theory of time to be a soft, psychological notion, irreconcilable with the quantitative realities of physics. Bergson, who gained fame as a philosopher by arguing that time should not be understood exclusively through the lens of science, criticized Einstein's theory of time for being a metaphysics grafted on to science, one that ignored the intuitive aspects of time. The Physicist and the Philosopher tells the remarkable story of how this explosive debate transformed our understanding of time and drove a rift between science and the humanities that persists today. Jimena Canales introduces readers to the revolutionary ideas of Einstein and Bergson, describes how they dramatically collided in Paris, and traces how this clash of worldviews reverberated across the twentieth century. She shows how it provoked responses from figures such as Bertrand Russell and Martin Heidegger, and carried repercussions for American pragmatism, logical positivism, phenomenology, and quantum mechanics. Canales explains how the new technologies of the period--such as wristwatches, radio, and film--helped to shape people's conceptions of time and further polarized the public debate. She also discusses how Bergson and Einstein, toward the end of their lives, each reflected on his rival's legacy--Bergson during the Nazi occupation of Paris and Einstein in the context of the first hydrogen bomb explosion. The Physicist and the Philosopher is a magisterial and revealing account that shows how scientific truth was placed on trial in a divided century marked by a new sense of time.

From Stonehenge to beyond the Big Bang, an exhilarating scientific exploration of how we make time Time is the grandest conception of the universe that we humans have been able to imagine – and its most intimate, the very frame of human life. In About Time, astrophysicist and award-winning writer Adam Frank tells the scientific story of this wonderful and tyrannical invention. A Palaeolithic farmer moved through the sun-fuelled day and star-steered night in a radically different way than the Elizabethan merchants who set their pace to the clocks newly installed in their town squares. Since then, science has swept time into increasingly minute and standardized units – the industrial efficiency of ironworks’ punch clocks; the space-age precision of atomic fountains and GPS satellites; the fifteen-minute increments of Outlook’s digital revolution. And in the past decade, string-theory branes, multiverses, and “clockless” physics have begun to overturn our ideas about how the universe began – the Big Bang – in ways that will completely rewrite time and our experience of it. Weaving cosmology with day-to-day chronicles and a down-to-earth style, About Time is both dazzling and riveting as it confronts what comes next.

Time - relentless, ever-present but intangible and the single element over which human beings have no absolute control - has long proved a puzzle. The author examines the phenomenon of time and asks such fascinating questions as how time impinges on people, to what extent our awareness of time is culturally conditioned, how societies deal with temporal problems and whether time can be considered a resource' to be economized. More specifically, he provides a consistent and detailed analysis of theories put forward by a number of thinkers such as Durkheim, Evans-Pritchard, Levi-Strauss, Geertz, Piaget, Husserl and Bourdieu. His discussion encompasses four main approaches in time research, namely developmental psychology, symbolic anthropology (covering the bulk of post-Durkheimian social anthropology) economic' theories of time in social geography and, finally, phenomenological theories. The author concludes by presenting his own model of social/cognitive time, in the light of these critical discussions of the literature.

"Patience, patience, because the great movements of history have always begun in those small parenthesis that we call 'in the meantime.'" --John Berger The last book that John Berger wrote was this precious little volume about time titled What Time Is It?, now posthumously published for the first time in English by Notting Hill Editions. Berger died before it was completed, but the text has been assembled and illustrated by his longtime collaborator and friend Sel uk Demirel, and has an introduction by Maria Nadotti. What Time Is It? is a profound and playful meditation on the illusory nature of time. Berger, the great art critic and Man Booker Prize-winning author, reflects on what time has come to mean to us in modern life. Our perception of time assumes a uniform and ceaseless passing of time, yet time is turbulent. It expands and contracts according to the intensity of the lived moment. We talk of time "saved" in a hundred household appliances; time, like money, is exchanged for the content it lacks. Berger posits the idea that time can lengthen lifetimes once we seize the present moment. "What-is-to-come, what-is-to-be-gained empties what-is."

The critical condition and historical motivation behind Time Studies The concept of time in the post-millennial age is undergoing a radical rethinking within the humanities. Time: A Vocabulary of the Present newly theorizes our experiences of time in relation to developments in post-1945 cultural theory and arts practices. Wide ranging and theoretically provocative, the volume introduces readers to cutting-edge temporal conceptualizations and investigates what exactly constitutes the scope of time studies. Featuring twenty essays that reveal what we talk about when we talk about time today, especially in the areas of history, measurement, and culture, each essay pairs two keywords to explore the tension and nuances between them, from "past/future" and "anticipation/unexpected" to "extinction/adaptation" and "serial/simultaneous." Moving beyond the truisms of postmodernism, the collection newly theorizes the meanings of temporality in relationship to aesthetic, cultural, technological, and economic developments in the postwar period. This book thus assumes that time-not space, as the postmoderns had it-is central to the contemporary period, and that through it we can come to terms with what contemporaneity can be for human beings caught up in the historical present. In the end, Time reveals that the present is a cultural matrix in which overlapping temporalities condition and compete for our attention. Thus each pair of terms presents two temporalities, yielding a generative account of the time, or times, in which we live.

Measuring the daily and yearly cycle of the cosmos has never been entirely straightforward. The year 2000 is alternatively the year 2544 (Buddhist), 6236 (Ancient Egyptian), 5761 (Jewish) or simply the Year of the Dragon (Chinese). The story of the creation of the Western calendar, which is related in this book, is a story of emperors and popes, mathematicians and monks, and the growth of scientific calculation to the point where, bizarrely, our measurement of time by atomic pulses is now more accurate than time itself: the Earth is an elderly lady and slightly eccentric - she loses half a second a century. Days have been invented (Julius Caesar needed an extra 80 days in 46BC), lost (Pope Gregory XIII ditched ten days in 1582) and moved (because Julius Caesar had 31 in his month, Augustus determined that he should have the same, so he pinched one from February). Published with the world under threat from chaos arising from the expiry of computer dates after 31st December 1999, this study links politics and religion, astronomy and mathematics, and Cleopatra and Stephen Hawking.

The revolution is here. In breakthrough after breakthrough, pioneering physicists are unlocking a new quantum universe which provides a better representation of reality than our everyday experiences and common sense ever could. The birth of quantum computers - which, like Schroedinger's famous dead-and-alive cat, rely on entities like electrons existing in a mixture of states - is starting to turn the computing world on its head. In his fascinating study of this cutting-edge technology (first published as Computing with Quantum Cats and now featuring a new foreword), John Gribbin updates his previous views on the nature of quantum reality, arguing for a universe of many parallel worlds where 'everything is real'. Looking back to Alan Turing's work on the Enigma machine and the first electronic computer, Gribbin explains how quantum theory developed to make quantum computers work in practice as well as in principle. He takes us beyond the arena of theoretical physics to explore their practical applications - from machines which learn through 'intuition' and trial and error to unhackable laptops and smartphones. And he investigates the potential for this extraordinary science to allow communication faster than light and even teleportation, as we step into a world of infinite possibility.
