"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.

From the bestselling, National Book Award-nominated auhtor of Genius and Chaos, a bracing new work about the accelerating pace of change in today's world.

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.

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.

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.

IN Time:A Traveller's Guide. CLifford A. Pickover takes readers to the forefront of science as he illuminates the most mysterious phenomenon in the universe - time itself. Is time travel possible? Is time real? Does it flow in one direction only? Does it have a beginning or an end? What is eternity? These are questions that Pickover tackles in this stimulating blend of Chopin, philosophy, Einstein and modern physics, spiced with diverting side-trips to such topics as the history of clocks, the nature of free will and the reason that gold glitters. By the time we finish this book, we understand such seemingly arcane concepts as space time diagrams, light cones, cosmic moment lines, transcendent infinite speeds, Lorentz transformations, superluminal and ultra-luminal motions, closed timelike curves, and Tipler cylinders. And most important, we will understand that time travel need not be confined to myth, science fiction, Hollywood fantasies, or scientific speculation. Time travel, we will realise, is possible.

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)

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 idea of time travel has tantalized humans for millennia. We can send humans into space, but roaming through time has eluded us. Do the laws of physics demand that we stay trapped in the present? This book examines the past, present and future states of time-travel research, but, also, looks at the bizarre anomalies of time itself.

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.

Biblical Foundations Award Finalist Holidays today are often established by legislation, and calendars are published on paper and smart phones. But how were holidays chosen and taught in biblical Israel? And what might these holidays have to do with the creation narrative? In this book, Michael LeFebvre considers the calendars of the Pentateuch with their basis in the heavenly lights and the land's agricultural cadences. He argues that dates were added to Old Testament narratives not as journalistic details but to teach sacred rhythms of labor and worship. LeFebvre then applies this insight to the creation week, finding that the days of creation also serve a liturgical purpose and not a scientific one. The Liturgy of Creation restores emphasis on the religious function of the creation week as a guide for Sabbath worship. Scholars, students, and church members alike will appreciate LeFebvre's careful scholarship and pastoral sensibilities.

From epigraphical, archaeological, and literary evidence Jon D. Mikalson has here assembled all relevant data concerning the dates of Athenian festivals, religious ceremonies, and legislative assemblies. This information has been used to revise and update our knowledge of the calendar as it reflects Athenian life. The facts and conclusions that emerge from the author's analysis correct some earlier assumptions. He brings to light new information concerning the meeting days of the Athenian Assembly and the Council, and establishes the days of the monthly festivals. Annual festivals are either dated exactly or fixed within closer time limits. The result of the author's rigorous approach is a collection of reliable evidence as to what religious and secular activities occurred on specific days of the Athenian year. Originally published in 1976. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

This book is about how big is the universe and how small are quarks, and what are the sizes of dozens of things between these two extremes. It describes the sizes of atoms and planets, quarks and galaxies, cells and sequoias. It is a romp through forty-five orders of magnitude from the smallest sub-nuclear particles we have measured, to the edge of the observed universe. It also looks at time, from the epic age of the cosmos to the fleeting lifetimes of ethereal particles. It is a narrative that trips its way from stellar magnitudes to the clocks on GPS satellites, from the nearly logarithmic scales of a piano keyboard through a system of numbers invented by Archimedes and on to the measurement of the size of an atom. Why do some things happen at certain scales? Why are cells a hundred thousandths of a meter across? Why are stars never smaller than about 100 million meters in diameter? Why are trees limited to about 120 meters in height? Why are planets spherical, but asteroids not? Often the size of an object is determined by something simple but quite unexpected. The size of a cell and a star depend in part on the ratio of surface area to volume. The divide between the size of a spherical planet and an irregular asteroid is the balance point between the gravitational forces and the chemical forces in nature. Most importantly, with a very few basic principles, it all makes sense. The world really is a most reasonable place.

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 OBSERVER BOOK OF THE YEAR From the acclaimed author of The Information and Chaos, a mind-bending exploration of time travel: its subversive origins, its evolution in literature and science, and its influence on our understanding of time itself. Gleick's story begins at the turn of the twentieth century with the young H. G. Wells writing and rewriting the fantastic tale that became his first book, an international sensation, The Time Machine. A host of forces were converging to transmute the human understanding of time, some philosophical and some technological - the electric telegraph, the steam railroad, the discovery of buried civilisations, and the perfection of clocks. Gleick tracks the evolution of time travel as an idea in the culture - from Marcel Proust to Doctor Who, from Woody Allen to Jorge Luis Borges. He explores the inevitable looping paradoxes and examines the porous boundary between pulp fiction and modern physics. Finally, he delves into a temporal shift that is unsettling our own moment: the instantaneous wired world, with its all-consuming present and vanishing future.

"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."

During the fifteenth and sixteenth centuries technical chronology, the study of calendars and of dates in ancient and medieval history, was both a fashionable and a controversial discipline. Theologians debated the dates of the Creation, the Flood, and the Crucifixion. Astronomers and historians argued about the identity of the eclipses that could supply absolute dates for events long past. Classical scholars reconstructed the religious beliefs and political practices that had governed the Greek and Roman calendars. Clerics and consultant experts, finally, debated what was to be done to mend the obviously faulty calendar of the western Church. Poliziano and Pico, Luther and Melanchthon, Copernicus and Kepler all studied and wrote about chronology. Late in the 1570s Joseph Scaliger (1540-1609) turned his attention to this field. He had already established himself as an innovative and ingenious editor of Latin texts, as the first volume of this study showed. But he now became one of the most celebrated scholars in Europe. He synthesized the work of dozens of other scholars, many of them now forgotten. He started or took part in many technical debates. And on such central problems as the date and nature of the Last Supper, the reliability of the various Old Testament texts, and the worth of the fragmentary historians of the ancient Near East, he showed remarkable erudition and insight. This book tells the stories of chronology and of Scaliger himself. It describes the scholarly circles in which he moved - above all the University of Leiden, the most innovative in Europe, where he spent the last decade and a half of his life. And it reconstructs his relations with contemporary scholars and scientists - notably Tycho Brahe and Johannes Kepler - and his remarkable, if wholly unofficial, career as a teacher. It is a sequel to volume I: Textual Criticism and Exegesis, published in 1983.

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.

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.

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.

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.

The Gregorian calendar reform of 1582, which provided the basis for the civil and Western ecclesiastical calendars still in use today, has often been seen as a triumph of early modern scientific culture or an expression of papal ambition in the wake of the Counter-Reformation. Much less attention has been paid to reform's intellectual roots in the European Middle Ages, when the reckoning of time by means of calendrical cycles was a topic of central importance to learned culture, as impressively documented by the survival of relevant texts and tables in thousands of manuscripts copied before 1500. For centuries prior to the Gregorian reform, astronomers, mathematicians, theologians, and even Church councils had been debating the necessity of improving or emending the existing ecclesiastical calendar, which throughout the Middle Ages kept losing touch with the astronomical phenomena at an alarming pace. Scandalous Error is the first comprehensive study of the medieval literature devoted to the calendar problem and its cultural and scientific contexts. It examines how the importance of ordering liturgical time by means of a calendar that comprised both solar and lunar components posed a technical-astronomical problem to medieval society and details the often sophisticated ways in which computists and churchmen reacted to this challenge. By drawing attention to the numerous connecting paths that existed between calendars and mathematical astronomy between the Fall of Rome and the end of the fifteenth century, the volume offers substantial new insights on the place of exact science in medieval culture.
