In the years since its publication in 1988, Stephen Hawking's A Brief History Of Time has established itself as a landmark volume in scientific writing.  It has become an international publishing phenomenon, translated into forty languages and selling over nine million copies.  The book was on the cutting edge of what was then known about the nature of the universe, but since that time there have been extraordinary advances in the technology of macrocosmic worlds.  These observations have confirmed many of Professor Hawkin's theoretical predictions in the first edition of his book, including the recent discoveries of the Cosmic Background Explorer satellite (COBE), which probed back in time to within 300,000 years of the fabric of space-time that he had projected.

Eager to bring to his original text the new knowledge revealed by these many observations, as well as his recent research, for this expanded edition Professor Hawking has prepared a new introduction to the book, written an entirely new chapter on the fascinating subject of wormholes and time travel, and updated the original chapters.

In addition, to heighten understanding of complex concepts that readers may have found difficult to grasp despite the clarity and wit of Professor Hawking's writing, this edition is enhanced throughout with more than 240 full-color illustrations, including satellite images, photographs made made possible by spectacular technological advance such as the Hubble Space Telescope, and computer generated images of three and four-dimensional realities.  Detailed captions clarify these illustrations, enable readers to experience the vastness of intergalactic space, the nature of black holes, and the microcosmic world of particle physics in which matters and antimatter collide.

A classic work that now brings to the reader the latest understanding of cosmology, A Brief History Of Time is the story of the ongoing search for t he tantalizing secrets at the heart of time and space.

Deep time is the timescale of the geological events that have shaped our planet. Whilst so immense as to challenge human understanding, its evidence is nonetheless visible all around us. Through explanations of the latest research and over 200 fascinating images, Deep Time explores this evidence, from the visible layers in ancient rock to the hiss of static on the radio, and from fossilized shark's teeth to underwater forests. These relics of ancient epochs, many of which we can see and touch today, connect our present to the distant past and answer broader questions about our place in the timeline of the Earth. Charting 4.5 billion years of geological history, this is the story of our world, from its birth to the dawn of civilization.

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.

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.

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.

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.

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.

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.

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.

A quirky, funny, and accessible blend of science and art that delves into the heart of Einstein’s theory of relativity

It was a link to Albert Einstein’s 1905 paper―an early attempt at explaining his revolutionary ideas on space, time, and matter―that drew Tanya Bub into his imaginative vision of the world. What particularly struck her was how Einstein interwove words and math to create clear visuals illustrating his theories. As an artist, she naturally started doodling as she worked her way through his concepts, creating drawings that intuitively demonstrated Einstein’s core principles.

In Reimagining Time, Tanya Bub teams up with her father, the distinguished physicist Jeffrey Bub, to create a quirky and accessible take on one of science’s most revolutionary discoveries. Blending original art and text, they guide readers―even nonmathematicians―through Einstein’s theory of special relativity to reveal truths about our universe: time is relative, lengths get shorter with motion, energy and mass are interchangeable, and the universe has a speed limit.

During times like these, who hasn't daydreamed about traveling forward or backward in time? In Time Travel: Ten Short Lessons, popular-science master Brian Clegg gives a grand tour of the essential lessons in this game-changing area of physics, from the imagination of novelists to current research. Einstein's special theory of relativity told us that time travel to the future was possible, and later his general theory of relativity showed us that loops in spacetime could exist, meaning that we might be able to bend time backward, too. But what are the practicalities of making time travel possible? What do we still need to know? How do we deal with paradoxical twists in time-and could quantum physics hold the answer? Packed full of easy-to-understand diagrams and fact boxes, these ten lessons cover all the basics, as well as the latest understanding and developments, to enlighten the nonscientist. About the series: The Pocket Einstein series is a collection of essential pocket-sized guides for anyone looking to understand a little more about some of the most important and fascinating areas of science in the twenty-first century. Broken down into ten simple lessons and written by leading experts in their field, discover the ten most important takeaways from those areas of science you've always wanted to know more about.

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.

Days, months, and years were given to us by nature, but we invented the week for ourselves. There is nothing inevitable about a seven-day cycle, or about any other kind of week; it represents an arbitrary rhythm imposed on our activities, unrelated to anything in the natural order. But where the week exists--and there have been many cultures where it doesn't--it is so deeply embedded in our experience that we hardly ever question its rightness, or think of it as an artificial convention; for most of us it is a matter of 'second nature.'

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.

Lunar calendars suffer from an inherent uncertainty in the length of each month and the number of months in the year. Variable atmospheric conditions, weather and the acuity of the eye of an observer mean that the first sighting of the new moon crescent can never be known in advance. Calendars which rely on such observations to define the beginning of a new month therefore suffer from this lack of certainty as to whether a month will begin on a given day or the next. The papers in this volume address the question of how ancient and medieval societies lived with the uncertainties of a lunar calendar. How did lack of foreknowledge of the beginning of the month impact upon administration, the planning of festivals, and historical record keeping? Did societies replace the observation of the new moon crescent with schematic calendars or calendars based upon astronomical calculations and what were the ideological and practical consequences of such a change? The contributors to this volume address these topics from the perspectives of a variety of Ancient Near Eastern, Jewish, Ancient and Medieval European, Asian and American cultures.

A tour of clocks throughout the centuries-from the sandglass to the telomere-to reveal the physical, biological, and social nature of time What is time? This question has fascinated philosophers, mathematicians, and scientists for thousands of years. Why does time seem to speed up with age? What is its connection with memory, anticipation, and sleep cycles? Award-winning author and mathematician Joseph Mazur provides an engaging exploration of how the understanding of time has evolved throughout human history and offers a compelling new vision, submitting that time lives within us. Our cells, he notes, have a temporal awareness, guided by environmental cues in sync with patterns of social interaction. Readers learn that, as a consequence of time's personal nature, a forty-eight-hour journey on the space shuttle can feel shorter than a six-hour trip on the Soyuz capsule, that the Amondawa of the Amazon do not have ages, and that time speeds up with fever and slows down when we feel in danger. With a narrative punctuated by personal stories of time's effects on truck drivers, Olympic racers, prisoners, and clockmakers, Mazur's journey is filled with fascinating insights into how our technologies, our bodies, and our attitudes can change our perceptions. Ultimately, time reveals itself as something that rides on the rhythms of our minds. The Clock Mirage presents an innovative perspective that will force us to rethink our relationship with time, and how best to use it.

Time is central to our lived experience of the world. Yet, as this book reveals, it is startlingly difficult to reconcile the way we seem to experience time with many of the theories presented to us in physics and metaphysics. This comprehensive and accessible introduction guides the unfamiliar reader through difficult questions at the intersection of the metaphysics and physics of time. It starts with the assumption that physics and metaphysics are inextricably connected, and that each can, and should, shed light on the other. The authors explore a range of views about the nature of time, showing how different these are from the way we typically think about time and our place in it. They consider such questions as: whether time travel is possible, and, if it is, whether we can change the past; whether there is a single moment that is objectively present; whether time flows or is static; and whether, ultimately, time exists at all. An Introduction to the Philosophy of Time will appeal to students of physics and philosophy who want both a comprehensive overview of the area and enough depth to allow for rigorous discussion. The book's detailed readings and exercises will challenge students and provide a clear roadmap for further study.

A readable and entertaining look at how Einstein's special theory of relativity gives us a new understanding of the nature of time Relativity ought to be an important part of everyone's education. Its subject is time, with which we all think we are familiar. Einstein's special theory of relativity reveals that some of our most intuitive notions about time are shockingly wrong. This clear, lively, and informal exposition of special relativity takes a highly original approach to introduce readers to the true nature of time. It is accessible to anyone who remembers a little high school algebra and elementary geometry. It's About Time offers deep insights to curious readers who have no technical scientific background.

Up until the end of the eighteenth century, the way Ottomans used their clocks conformed to the inner logic of their own temporal culture. However, this began to change rather dramatically during the nineteenth century, as the Ottoman Empire was increasingly assimilated into the European-dominated global economy and the project of modern state-building began to gather momentum. In Reading Clocks, Alla Turca, Avner Wishnitzer unravels the complexity of Ottoman temporal culture and for the first time tells the story of its transformation. He explains that in their attempt to attain better surveillance capabilities and higher levels of regularity and efficiency, various organs of the reforming Ottoman state developed elaborate temporal constructs in which clocks played an increasingly important role. As the reform movement spread beyond the government apparatus, emerging groups of officers, bureaucrats, and urban professionals incorporated novel time-related ideas, values, and behaviors into their self-consciously "modern" outlook and lifestyle. Acculturated in the highly regimented environment of schools and barracks, they came to identify efficiency and temporal regularity with progress and the former temporal patterns with the old political order. Drawing on a wealth of archival and literary sources, Wishnitzer's original and highly important work presents the shifting culture of time as an arena in which Ottoman social groups competed for legitimacy and a medium through which the very concept of modernity was defined. Reading Clocks, Alla Turca breaks new ground in the study of the Middle East and presents us with a new understanding of the relationship between time and modernity.

Time is the one thing that is shared by all of humanity, irrespective of wealth, health, race or credo; and one of the things that makes us individual is how we choose to spend it. It is one of the commodities over which we have most control, yet it is the asset we value the least. Isn't it time we took control over how we spend it, while we still can? Time will reward readers of lifestyle quests who seek a better, richer, slower, more fulfilling way of life. For anyone who has ever pondered the paradoxes of time and who is interested in looking at their world from a fresh perspective. Whether you want the encouragement to take time out on a life-scale or simply adjust your life to accommodate a timetable that suits you, this book will have plenty of inspiration, suggestions and tips to help you get the most out of your time.

How old is Earth? Can we look back in time? How long is a light year? How short is a femtosecond? What is Greenwich Mean Time? How did astronauts tell the time on the Moon? When did time begin? It's high time you knew the answers to these and many more intriguing questions, so why not pass the time reading this lighthearted, illustrated miscellany, packed with hundreds of amazing facts from the time experts at the Royal Observatory. In less than no time, you'll have discovered the myriad of influences that time has on our daily lives.

As new networks of railways, steamships, and telegraph communications brought distant places into unprecedented proximity, previously minor discrepancies in local time-telling became a global problem. Vanessa Ogle's chronicle of the struggle to standardize clock times and calendars from 1870 to 1950 highlights the many hurdles that proponents of uniformity faced in establishing international standards. Time played a foundational role in nineteenth-century globalization. Growing interconnectedness prompted contemporaries to reflect on the annihilation of space and distance and to develop a global consciousness. Time-historical, evolutionary, religious, social, and legal-provided a basis for comparing the world's nations and societies, and it established hierarchies that separated "advanced" from "backward" peoples in an age when such distinctions underwrote European imperialism. Debates and disagreements on the varieties of time drew in a wide array of observers: German government officials, British social reformers, colonial administrators, Indian nationalists, Arab reformers, Muslim scholars, and League of Nations bureaucrats. Such exchanges often heightened national and regional disparities. The standardization of clock times therefore remained incomplete as late as the 1940s, and the sought-after unification of calendars never came to pass. The Global Transformation of Time reveals how globalization was less a relentlessly homogenizing force than a slow and uneven process of adoption and adaptation that often accentuated national differences.
