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.

An invaluable resource for working programmers, as well as a fount of useful algorithmic tools for computer scientists, astronomers, and other calendar enthusiasts, The Ultimate Edition updates and expands the previous edition to achieve more accurate results and present new calendar variants. The book now includes coverage of Unix dates, Italian time, the Akan, Icelandic, Saudi Arabian Umm al-Qura, and Babylonian calendars. There are also expanded treatments of the observational Islamic and Hebrew calendars and brief discussions of the Samaritan and Nepalese calendars. Several of the astronomical functions have been rewritten to produce more accurate results and to include calculations of moonrise and moonset. The authors frame the calendars of the world in a completely algorithmic form, allowing easy conversion among these calendars and the determination of secular and religious holidays. LISP code for all the algorithms is available in machine-readable form.

Can we see the future in our dreams? Does time flow in one direction? What is a 'meaningful coincidence'? Renowned esoteric writer Gary Lachman has been recording his own precognitive dreams for forty years. In this unique and intriguing book, Lachman recounts the discovery that he dreams 'ahead of time', and argues convincingly that this extraordinary ability is, in fact, shared by all of us. Dreaming Ahead of Time is a personal exploration of precognition, synchronicity and coincidence drawing on the work of thinkers including J.W. Dunne, J.B. Priestly and C.G. Jung. Lachman's description and analysis of his own experience introduces readers to the uncanny power of our dreaming minds, and reveals the illusion of our careful distinctions between past, present and future.

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.

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.

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.

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 engages all readers interested in how 'telling the time' has come to dominate our way of life.

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.

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.

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.

Most of us suffer some degree of "hurry sickness." a malady that has launched us into the "epoch of the nanosecond," a need-everything-yesterday sphere dominated by cell phones, computers, faxes, and remote controls. Yet for all the hours, minutes, and even seconds being saved, we're still filling our days to the point that we have no time for such basic human activities as eating, sex, and relating to our families. Written with fresh insight and thorough research, Faster is a wise and witty look at a harried world not likely to slow down anytime soon.

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.

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.

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)

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.

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.
