This book is about structural relations between phenomenological and neurophysiological aspects of consciousness and time. Focusing on auditory perception and making new and updated use of Leibniz and Husserl, it investigates the transition from unconscious to conscious states, especially with regard to the constitution of phenomenal time.
What is Time? Assuming no prior specialized knowledge by the reader, the book raises specific, hitherto overlooked questions about how time works, such as how and why anyone can be made to be, at the very same instant, simultaneous with events that are actually days apart. It examines abiding issues in the physics of time or at its periphery which still elude a full explanation such as delayed choice experiments, the brain's perception of time during saccadic masking, and more and suggests that these phenomena can only exist because they ultimately obey applicable mathematics, thereby agreeing with a modern view that the universe and everything within it, including the mind, are ultimately mathematical structures. It delves into how a number of conundrums, such as the weak Anthropic Principle, could be resolved, and how such resolutions could be tested experimentally. All its various threads converge towards a same new vision of the ultimate essence of time, seen as a side effect from a deeper reality.
The concept of time has fascinated humanity throughout recorded history, and it remains one of the biggest mysteries in science and philosophy. Time is clearly one of the fundamental building blocks of the universe and thus a deeper understanding of nature at a fundamental level also demands a comprehension of time. Furthermore, the origins of the universe are closely intertwined with the puzzle of time: Did time emerge at the Big Bang? Why does the arrow of time 'conspire' with the order of the initial state of the universe? This book addressesmany ofthe most important questions about time: What is time, and is it fundamental or emergent? Why is there such an arrow of time, closely related to the initial state of the universe, and why do the cosmic, thermodynamic and other arrows agree? These issues are discussed here by leading experts, and each offers a new perspective on the debate. Their contributions delve into the most difficult research topic in physics, also describing the latest cutting edge research on the subject. The book also offers readers a comparison between the different outlooks of philosophy, physics and cosmology on the puzzle of time. This volume is intended to be useful for research purposes, but most chapters are also accessible to a more general audience of scientifically educated readers looking for deeper insights. "
Time is fundamental to our experience, but remains mysterious. This book shows how philosophers and scientists have tried to grapple with this most extraordinary of ordinary phenomena. From the attempts of early astronomers to reconcile solar and lunar and terrestrial reckonings, to the huge expansions and contractions of time consciousness brought on by scientists as diverse as Newton, Darwin, and Einstein, this book shows how time is as much a matter of human choice as it is a matter of scientific precision.
What is time? What do we understand when we think about time? What do we mean by ‘now’? This book covers concisely all the different aspects of time with an anchoring point within the geological sciences. Here successions of strata are seen as representing successions of events in the long history of the earth; palaeontology provides a record of organic evolution through nearly the whole of these several thousand million years. The rest of the book diversifies in discussing the measurement of time both physically and biologically; our human perception of it; the ending of personal time in death; the pervading presence of time in the arts; out through astronomy to cosmology; into philosophy and religion. The idea of time is a very complex one but this book undertakes a journey to prove that it is not beyond comprehension.
Causal relations, and with them the underlying null cone or conformal structure, form a basic ingredient in all general analytical studies of asymptotically flat space-time. The present book reviews these aspects from the analytical, geometrical and numerical points of view. Care has been taken to present the material in a way that will also be accessible to postgraduate students and nonspecialist reseachers from related fields.
The aim of this interdisciplinary study is to reconstruct the evolution of our changing conceptions of time in the light of scientific discoveries. It will adopt a new perspective and organize the material around three central themes, which run through our history of time reckoning: cosmology and regularity; stasis and flux; symmetry and asymmetry. It is the physical criteria that humans choose - relativistic effects and time-symmetric equations or dynamic-kinematic effects and asymmetric conditions - that establish our views on the nature of time. This book will defend a dynamic rather than a static view of time.
The non-technical, basic yet familiar features of time are investigated, e.g. two novel, detailed arguments defending the common view that 'time rolls relentlessly' are advanced; a number of hitherto neglected fundamental differences between spatio-temporal location and every other physical property are discussed; the unresolved problem, why the past is so much better known than the future is tackled. For those who wish to delve deeper, 25% of the book consists of problems to ponder and their possible solutions.
The volume offers a comprehensive introduction to the sociology of time. Based on selected contributions from leading writers, it illustrates the range of issues and perspectives which define the field. The volume traces distinct traditions of time analysis in social science and uses these to explain, for example, the development of capitalist time-consciousness, the ways we structure time in organizations and institutions, and how our time perceptions change in line with changes in culture. The book is for those who wish to understand how time comes to condition our everyday actions and affairs.
This book traces the development of the Jewish calendar from its origin until it reached, in the tenth century CE, its present form. Drawing on a wide range of sources - literary, documentary and epigraphic; Jewish, Graeco-Roman and Christian - this is the first comprehensive book to have been written on this subject. The unification of the calendar is seen as an element in the unification of Jewish identity.
This is a book about real time in economics, a dimension increasingly unused by the edge of the profession. This, it is argued, has serious implications for economics' role as the premier policy-advising source for national governments and international organizations. It is also a book about the great waves of economic change that economists have failed even to identify, let alone analyze. This failure has created an intellectual vacuum that natural scientists are now only attempting to fill. It is a book, therefore, that challenges economics to put its house in order before it is engulfed by this rising tide. But, the question is, will economics have time? By the author of "Depression and Recovery: Western Australia 1929-1939", "Exploring Southeast Asia's Economic Past" and "Domesday Economy: A New Approach to Anglo-Norman History".
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.
The story of how an eleven-year old boy growing up in 16th century Italy loses his birthday when the Gregorian calendar replaces the Julian calendar in 1582, and how he fights to prevent this loss. The author cleverly weaves elements of the cultural and scientific milieu of the time into an engaging and intelligent tale. Tibaldos father is a medical assistant, and his sister is a midwife. Thus, the boy grows up learning about current medical practices and his fascination for medicine makes him a fast learner. Then, when Tibaldo learns that he is about to lose his 13th birthday, he determines to do something about it. The result is both amusing and informative.

In the first book which deals entirely with the subject of time in Africa and the Black Diaspora, Adjaye presents ten critical case studies of selected communities in Africa, the Caribbean, and the American South. The essays cover a wide spectrum of manifestations of temporal experience, including cosmological and genealogical time, physical and ecological cycles, time and worldview, social rhythm, agricultural and industrial time, and historical processes and consciousness. The studies confirm the continuity of temporal experience among Africans from pre-colonial times, through the colonial period in Africa, across continents through slavery and Maroon societies, to present-day communities like the Gullah of the Sea Islands of South Carolina. The subject of time, now recognized to be relative rather than uniform, draws together evidence from a variety of disciplines, specifically history, linguistics, political science, anthropology, and philosophy.
The system of numbering the years A.D. (Anni Domini, Years of the
Lord) originated with Dionysius Exiguus. Dionysius drafted a
95-year table of dates for Easter beginning with the year 532 A.D.
Why Dionysius chose the year that he did to number as '1' has been
a source of controversy and speculation for almost 1500 years.
According to the Gospel of Luke (3.1; 3.23), Jesus was baptized in
the 15th year of the emperor Tiberius and was about 30 years old at
the time. The 15th year of Tiberius was A.D. 29. If Jesus was 30
years old in A.D. 29, then he was born in the year that we call 2
B.C. Most ancient authorities dated the Nativity accordingly.
Following one of the most inspiring and fascinating stories linked to the Royal Observatory, Greenwich, this book centres on the life and achievements of John Harrison - designer and builder of the first accurate marine chronometers. Inspired by the official prize offered in 1714 to anyone who could solve the problem of finding longitudinal position at sea, Harrison produced his four famous 'H' timepieces. In doing so, he helped revolutionise sea travel, saving many thousands of lives. John Harrison and the Quest for Longitude is the intriguing account of one man driven by the need to solve one of the greatest practical problems of his time.
Interest in the concept of time has a long history and has been a topic of study for a wide range of investigators. No change can take place without specification of time. While philosophers and physicists have been intrigued by the concept of subjective perception of time and its relationship to real time, natural scientists have been concerned mainly with investigating time as a factor in understanding the behaviour of animals from the migratory habits of birds to the periodical breeding cycles. The immense bulk of temporal perception studies, the variety of approaches, methods of measurement and even terminology has led to a difficulty in reaching a global interpretation of the results. This book aims to give an integrative approach of time sense and to focus the analysis on temporal factors in the processing of movement, trying to link temporal perception studies in the final common pathway, that is motion. To give some clues of human brain integrative processes at higher levels. And, finally, to clarify the neurophysiological substrate of these operations.
Space and time on earth are regulated by the prime meridian, 0 Degrees, which is, by convention, based at the Royal Observatory, Greenwich. But the meridian's location in southeast London is not a simple legacy of Britain's imperial past. Before the nineteenth century, more than twenty-five different prime meridians were in use around the world, including Paris, Beijing, Greenwich, Washington, and the location traditional in Europe since Ptolemy, the Canary Islands. Charles Withers explains how the choice of Greenwich to mark 0 Degrees longitude solved complex problems of global measurement that had engaged geographers, astronomers, and mariners since ancient times. Withers guides readers through the navigation and astronomy associated with diverse meridians and explains the problems that these cartographic lines both solved and created. He shows that as science and commerce became more global and as railway and telegraph networks tied the world closer together, the multiplicity of prime meridians led to ever greater confusion in the coordination of time and the geographical division of space. After a series of international scientific meetings, notably the 1884 International Meridian Conference in Washington, DC, Greenwich emerged as the most pragmatic choice for a global prime meridian, though not unanimously or without acrimony. Even after 1884, other prime meridians remained in use for decades. As Zero Degrees shows, geographies of the prime meridian are a testament to the power of maps, the challenges of accurate measurement on a global scale, and the role of scientific authority in creating the modern world.
The book focuses on the study of the temporal behavior of complex many-particle systems. The phenomenon of time and its role in the temporal evolution of complex systems is a remaining mystery. The book presents the necessity of the interdisciplinary point of view regarding on the phenomenon of time.The aim of the present study is to summarize and formulate in a concise but clear form the trends and approaches to the concept of time from a broad interdisciplinary perspective exposing tersely the complementary approaches and theories of time in the context of thermodynamics, statistical physics, cosmology, theory of information, biology and biophysics, including the problem of time and aging. Various approaches to the problem show that time is an extraordinarily interdisciplinary and multifaceted underlying notion which plays an extremely important role in various natural complex processes.
