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.

George Synkellos, a monk of Constantinople who once held a position of authority under the patriarch Tarasios, composed (in Greek) a chronicle of universal history in the early ninth century. Beginning with the creation of the universe, the chronicle preserves a rich collection of ancient sources, many of them otherwise unknown. The English translation provided here, together with introduction and notes, promises to make this influential and wide-ranging history more accessible.

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.

"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.

This book offers a detailed and fascinating picture of the astonishing astronomical knowledge on which the Roman calendar, traditionally attributed to the king Numa Pompilius (reign 715-673 B.C.), was based. This knowledge, of Mesopotamian origins, related mainly to the planetary movements and to the occurrence of eclipses in the solar system. The author explains the Numan year and cycle and illustrates clearly how astronomical phenomena exerted a powerful influence over both public and private life. A series of concise chapters examine the dates of the Roman festivals, describe the related rites and myths and place the festivals in relation to the planetary movements and astronomical events. Special reference is made to the movements of the moon and Venus, their relation to the language of myth, and the particular significance that Venus was considered to have for female fertility. The book clearly demonstrates the depth of astronomical knowledge reflected in the Roman religious calendar and the designated festive days. It will appeal both to learned connoisseurs and to amateurs with a particular interest in the subject.

We are directed to "mind the time" on occasions when diligence to the clock is important. However, to deliberately invoke "mind your time" is to remember how quickly time, and the clock which serves as its agent, can so quickly recede into the mundane and taken for granted parts of our lives. The experience of time in families can both permeate all activities but nevertheless be hidden. The papers in this volume, representing a range of disciplines (history, sociology, psychology, family therapy, leisure studies, family science) intentionally foreground the way that time shapes everyday family worlds. Each chapter offers different insights into the way that we conceptualize time including analyses of pace, rhythm, negotiation, politics, timetables, schedules, social interaction and support. The meaning of time is illustrated through analyses of a variety of family issues including father involvement, infertility, work and family, mothering and care work, housework, family time, single parent families, family life education and gender.

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.

This book studies the transition from local to national timekeeping, a process that led to Standard Time--the world-wide system of timekeeping by which we all live. Prior to the railroads' adoption of Standard Railway Time in 1883, timekeeping was entirely a local matter, and America lacked any uniform system to coordinate times and public activities. For example, in the middle of the nineteenth century, Boston had three authoritative times, which differed by seconds and minutes.
The story begins in the 1830s with the building of the first railroads. Since railway safety depended upon maintaining the temporal separation of trains through precise timing, railroads were the first to establish time standards to govern their operations. The railroads' switch to five time standards indexed to the Greenwich meridian inaugurated the modern era of public timekeeping and led directly to cities adopting Greenwich-indexed civil time zones.
Central to the story are those college and university astronomers who, starting in the 1850s, sold time signals to nearby cities and railroads. From the start, they competed with other entrepreneurs trying to make money by selling time. Decades of negotiations, government lobbying, and battles over customers followed, all in the name of "public service." Improvements by a host of clockmakers, civil and electrical engineers, telegraph and railway technicians, and instrument makers finally changed the market for accurate time. Public timekeeping became the realm of business investors.
Despite the efforts of astronomers and various of their Congressional supporters, who argued for the necessity of a national system of time authorized by the federal government, the railroads' success with their own system blocked legislation for a national system of time until the First World War. By then, a single source for correct time dominated the public's timekeeping: the U.S. Naval Observatory's noon signal.
In this first comprehensive, scholarly history of timekeeping in America, the author has drawn upon a rich, untapped archival record, municipal and legislative documents, newspapers, and science and engineering journals to challenge several myths that have grown up around the subject.

A look at the competing notions of time in the middle ages, from the spiritual - death, the Last Judgement - to the practical - lawyers' calculations, clocks and calendars. By exploring some of the more important senses of time which were in circulation in the medieval world, scholars from a wide range of disciplines trace competing definitions and modes of temporality in the middle ages, explainingtheir influence upon life and culture. The issues explored include anachronism as a feature in earlier senses of time, perceptions of death and of the Last Judgement, time in literary narratives and in music, constructions of timeas used in the professions, and original work on the particular systems and technologies which were used for the keeping of time, such as clocks and calendars.

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.

Sundials, which decorate church walls, public plazas, and elegant gardens, are first and foremost astronomical instruments. Before understanding how sundials work, one must first understand the apparent motion of the Sun in the sky. In this book, Denis Savoie presents the basics of astronomy required to understand sundials and describes how to design and build your own classical sundial. Written to engage all levels of science readers, the author shows the calculations involved in the sundial's construction and also gives a comprehensive history of time measurement.

The book begins with an introduction to cosmography through a study of the Sun's annual and diurnal motions. The Celestial Sphere and the local Celestial Sphere, the hour angle of the sun and the equation of Time are all discussed. The author then moves to a brief history of both sundials and time, giving the general principles behind the sundial, the conversion of solar time to clock time, and discussing the local meridian line. The gnomon and the use of its shadow are also explained in detail. In addition, many types of sundials and their different uses are described. These include the polar, horizontal, and north-facing sundial, just to name a few.

The practical and observational aspects of sundials will enable readers to create custom-made sundial of their own, adding whatever special features they wish to include. Most of these designs have been tested by people with no previous knowledge of astronomy. To aid the reader, the book is full of clear and instructive illustrations and diagrams.

Does time really flow, or is that simply an illusion? Did time have a beginning? What does it mean to say that time has a direction? Does space have boundaries, or is it infinite? Are our space and time unique, or could there be other, parallel worlds with their own space and time? Do space and time really exist, or are they simply the constructions of our minds?

Robin Le Poidevin provides a clear, witty, and stimulating introduction to these deep questions, and many other mind-boggling puzzles and paradoxes. He gives a vivid sense of the difficulties raised by our ordinary ideas about space and time, but he also gives us the basis to think about these problems independently, avoiding large amounts of jargon and technicality. No prior knowledge of philosophy is required to enjoy this book. The universe might seem very different after reading it.

What is time? What does it mean for time to pass? Is it possible to travel in time? What is the difference between the past and future? Until the work of Newton, these questions were purely topics of philosophical speculation. Since then we've learned a great deal about time, and its study has moved from a subject of philosophical reflection to instead became part of the subject matter of physics. This Very Short Introduction introduces readers to the current physical understanding of the direction of time, from the Second Law of Thermodynamics to the emergence of complexity and life. Jenann Ismael charts the line of development in physical theory from Newton, via Einstein's Theory of Relativity, to the current day. Einstein's innovations led to a vision of time very different from the familiar time of everyday sense. In this new vision, time is one of the dimensions in which the universe is extended alongside the spatial dimensions. The universe appears as a static block of events, in which there is no more a difference between past and future than there is between east and west. Discussing the controversy and philosophical confusion which surrounded the reception of this new vision, Ismael also covers the contemporary mixture of statistical mechanics, cognitive science, and phenomenology that point the way to reconciling the familiar time of everyday sense with the vision of time presented in Einstein's theories. Very Short Introductions: Brilliant, Sharp, Inspiring ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.

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.

The author discusses whether time travel is scientifically possible. He examines "the history of the development of general relativity, the conceptof curved space-time and the early evolution of the universe. The remainder of the book seeks to] explain the problems that arise when we attempt to turntheoretical holes in space-time into time machines." (N Y Times Book Review)

An engaging, encyclopedic account of the material world of early modern Britain as told through a unique collection of dated objects The period from 1500 to 1800 in England was one of extraordinary social transformations, many having to do with the way time itself was understood, measured, and recorded. Through a focused exploration of an extensive private collection of fine and decorative artworks, this beautifully designed volume explores that theme and the variety of ways that individual notions of time and mortality shifted. The feature uniting these more than 450 varied objects is that each one bears a specific date, which marks a significant moment-for reasons personal or professional, religious or secular, private or public. From paintings to porringers, teapots to tape measures, the objects-and the stories they tell-offer a vivid sense of the lived experience of time, while providing a sweeping survey of the material world of early modern Britain.

Timekeeping is an essential activity in the modern world, and we take it for granted that our lives our shaped by the hours of the day. Yet what seems so ordinary today is actually the extraordinary outcome of centuries of technical innovation and circulation of ideas about time.
Shaping the Day is a pathbreaking study of the practice of timekeeping in England and Wales between 1300 and 1800. Drawing on many unique historical sources, ranging from personal diaries to housekeeping manuals, Paul Glennie and Nigel Thrift illustrate how a particular kind of common sense about time came into being, and how it developed during this period.
Many remarkable figures make their appearance, ranging from the well-known, such as Edmund Halley, Samuel Pepys, and John Harrison, who solved the problem of longitude, to less familiar characters, including sailors, gamblers, and burglars.
Overturning many common perceptions of the past-for example, that clock time and the industrial revolution were intimately related-this unique historical study will engage all readers interested in how "telling the time" has come to dominate our way of life.

This book brings Christian theology, creative literature and literary critical theory into dialogue on the theme of "the end." Where appropriate it also considers recent scientific views on the nature of time.

'Postmodern' critical theorists and many other writers emphasize the 'open' nature of endings, but this book suggests that the mixture of openness and closure in Christian eschatology not only offers a coherent sense of an ending, but may make it possible to construct endings in the here and now. On the way to this conclusion the book provides an exegesis of novels, plays and poems by such writers as John Fowles, Julian Barnes, Doris Lessing, Samuel Beckett, T. S. Eliot, Virginia Woolf, James Joyce and Shakespeare. Among critical theorists, postmodern and otherwise, it considers especially the ideas of Frank Kermode, Northrop Frye, Jacques Derrida and Paul Ricoeur.

The author also examines the main themes of Christian eschatology - such as death, parousia, resurrection, human destiny and the nature of eternity - and offers a critical view of the doctrines of the last things produced by major modern theologians, including Jurgen Moltmann and Wolfhart Pannenberg. Through this dialogue the book aims to form an image of the eternal 'wholeness' of persons in the life of the triune God that takes seriously the deconstruction of images of domination.

Our engagement with time is a ubiquitous feature of our lives. We are aware of time on many scales, from the briefest flicker of change to the way our lives unfold over many years. But to what extent does this encounter reveal the true nature of temporal reality? To the extent that temporal reality is as it seems, how do we come to be aware of it? And to the extent that temporal reality is not as it seems, why does it seem that way? These are the central questions addressed by Simon Prosser in Experiencing Time. These questions take on a particular importance in philosophy for two reasons. Firstly, there is a view concerning the metaphysics of time, known as the B-theory of time, according to which the apparently dynamic quality of change, the special status of the present, and even the passage of time are all illusions. Instead, the world is a four-dimensional space-time block, lacking any of the apparent dynamic features of time. If the B-theory is correct, as the book argues, then it must be explained why our experiences seem to tell us otherwise. Secondly, experiences of temporal features such as changes, rates and durations are of independent interest because of certain puzzles that they raise, the solutions to which may shed light on broader issues in the philosophy of mind.

All religion and much philosophy has been concerned with the contrast between the ephemeral and the eternal. Human beings have always sought ways to overcome time, and to prove that death is not the end. This book consists then in an exploration of certain closely related ideas: personal identity, time, history and our commitment to the future, and the role of imagination in life.

Warnock argues in particular that the notion of personal immortality, as it appears in Christian dogma, cannot be taken literally. Nevertheless, as a metaphor, immortality may illuminate both our relation with the past, our understanding of the present and our responsibility for the future. In the course of the argument, philosophical themes of personal identity, of history, and of values, are explored, as well as the cognitive content of the imagination.

In 2004 a rock star, a TV astronomer and a young research astronomer sat down to write the story of the Universe in the order in which it happened, from its birth at the Big Bang 13.7 billion years ago, through to its ultimate demise in the infinitely far future. The aim of this book is to explain the Big Bang and everything that followed in a way that made sense, in the strict order in which events occurred, and without using maths, so it would be understandable to everyone, regardless of educational background. The original edition of Bang! was a bestseller, and a go-to for anyone wanting to understand the story of the origins and evolution of our Universe that did not duck the science. Since the first edition, thousands of planets have been discovered, the 'habitable zone' has expanded and a flotilla of new satellites has explored our own solar system, bringing back fresh images and new science. In this book all the latest findings about the evolution of stars and galaxies are included, and the current thinking about our ultimate origins. The latest ideas about Dark Matter and Dark Energy are explained, all illustrated with new images from the world's largest telescopes and space missions. This is the new, updated, popular guide to 'Life, the Universe, and Everything' - The Complete History of the Universe.

Why does time appear to run in only one direction? We remember the past- but why not the future? We can influence the future- but could we, even theoretically, influence the past?

Generations of philosophers and theologians, physicists and mathematicians have puzzles and speculated about these and the many other questions that surround the concept of time. Recent scientific work is said to explain the directionality of time. But time still contains many mysteries- black holes and big bangs, asymmetries and relativities, arrows and loops - that will doubtless continue to occupy us for centuries to come.

In this impressive collection of original articles ten internationally known scholars explore and explains the nature of time, apace and now space-time. Founded on the latest developments in thermodynamics, quantum theory and cosmology, their ideas will fascinate anyone interested in Einstein's theory of relativity.
