Could the Big Bang Theory be flawed? Berossa's Illusion of Time is driven by the question of why gravity affects time. In a model that shows the rate of time evolving with the age of an atom, the author shows that purely physical changes in atoms will account for red shifts seen in distant cosmological objects. This is based simply on differences between clock rates then and now, and such red shifts are virtually indistinguishable from those associated with galaxies receding in bulk flows in a Doppler expansion. In short, Berossa's thesis suggests that "Doppler velocities" of galaxies found in the Big Bang Theory may be largely an illusion. Berossa's extended thought-experiment also produces an elegant explanation of how the atom might work. It eliminates the need for the atomic strong and weak forces to explain how naturally repelling particles co-exist within atoms. Time and gravity are linked fundamentally to light and mass. He offers the reader an intellectual ride through the realm of physics that is not for the faint-hearted.

With our busy schedules today everyone seems to be in a hurry with little time to retrieve information such as the day of the week of Christmas 2010 or the day of the week the first man landed on the moon on July 20, 1969. The 300 Year Calendar Book will solve these problems fast. Indeed, using this book one could very easily and quickly find any day of the week in the years between 1760 to 2060. Furthermore, if one remembers the constant number of any given month of any year one could determine the day of the week instantly by application of the Koay Calendar Formula. This is the intention of this book. It saves one's time, reduces one's frustration and helps to keep one's blood pressure normal. The authors' goal is to share this convenience with everyone. Over 150 years ago, Dumas stated well "one for all and all for one" in his book The Three Musketeers. The authors admire his philosophy.

Essays and letters of the author analyzing the means of achieving human happiness through constructive social program. Written during the Civil War, it represents the transformation of an art critic into a social reformer.

A dramatic new account of the parallel quests to harness time that culminated in the revolutionary science of relativity, "Einstein's Clocks, Poincare's Maps" is "part history, part science, part adventure, part biography, part meditation on the meaning of modernity....In Galison's telling of science, the meters and wires and epoxy and solder come alive as characters, along with physicists, engineers, technicians and others....Galison has unearthed fascinating material" ("New York Times"). Clocks and trains, telegraphs and colonial conquest: the challenges of the late nineteenth century were an indispensable real-world background to the enormous theoretical breakthrough of relativity. And two giants at the foundations of modern science were converging, step-by-step, on the answer: Albert Einstein, an young, obscure German physicist experimenting with measuring time using telegraph networks and with the coordination of clocks at train stations; and the renowned mathematician Henri Poincare, president of the French Bureau of Longitude, mapping time coordinates across continents. Each found that to understand the newly global world, he had to determine whether there existed a pure time in which simultaneity was absolute or whether time was relative. Esteemed historian of science Peter Galison has culled new information from rarely seen photographs, forgotten patents, and unexplored archives to tell the fascinating story of two scientists whose concrete, professional preoccupations engaged them in a silent race toward a theory that would conquer the empire of time."

The third edition of Signals and Systems prepares students for real-world engineering applications. It is concise, focused, and practical. The text introduces basic concepts in signals and systems and their associated mathematical and computational tools. It also stresses the most important concepts in signal analysis (frequency spectra) and system analysis (stability and frequency responses) and uses them throughout, including the study of seismometers and accelerometers.
Signals and Systems, 3/e, introduces every term carefully and develops every topic logically. It distinguishes amplitudes and magnitudes, as well as lumped and distributed systems. It presents engineering concepts as early as possible and discusses transform theory only as needed. Also, the text employs transfer functions and state-space equations only in the contexts where they are most efficient. Transfer functions are used exclusively in qualitative analysis and design, and state-space equations are used exclusively in computer computation and op-amp circuit implementation. Thus, the students' time is focused on learning only what can be immediately used.
Including an author commentary on the best way to approach the text, Signals and Systems, 3/e, is ideal for sophomore- and junior-level undergraduate courses in systems and signals. It assumes a background in general physics (including simple circuit analysis), simple matrix operations, and basic calculus.

The history of the clock opens a window on how different cultures have viewed time and on Europe's path to industrialization.

How did a time-keeping device affect the growth of crafts guilds and the scientific research that led to the Industrial Revolution? Clocks and Culture is a brief history of the changes wrought by and on Europe over four hundred years due to technological advances in timekeeping and the rise of a time-aware culture. In his introduction, Anthony Grafton, Henry Putnam University Professor of History at Princeton University, puts this classic book in perspective. 14 b/w illustrations.

"Cipolla has a sharp eye for the heaven in a grain of sand. He takes a prosaic piece of hardware and uses it as a path into some of the central themes of history.... Imaginative and wide-ranging."—The Economist

With his unique knack for making cutting-edge theoretical science effortlessly accessible, world-renowned physicist Paul Davies now tackles an issue that has boggled minds for centuries: Is time travel possible? The answer, insists Davies, is definitely yes—once you iron out a few kinks in the space-time continuum. With tongue placed firmly in cheek, Davies explains the theoretical physics that make visiting the future and revisiting the past possible, then proceeds to lay out a four-stage process for assembling a time machine and making it work. Wildly inventive and theoretically sound, How to Build a Time Machine is creative science at its best—illuminating, entertaining, and thought provoking.

In this text, science writer Barry Parker takes on one of the most fascinating and fantastical aspects of modern quantum theory - time travel. From the stuff of fiction to Einstein's theory of relativity and Hawking's view of the universe, time travel has captured modern man's excitement and been as much talked about as space travel.

This book marks the Millenium. It contains the new simplified perpetual calendar that will replace the old 336 page Roman calendar of 2046 years, with one single permanent page.

The articles here are not only about time, they are investigations from a specific temporal perspective: the calendrical event of the millennium. This arbitrary marker has provided a challenge and focus to the International Society for the Study of Time and to thinkers in all disciplines to take stock of what has gone before and what lies ahead, approaching the event of the millennium from the standpoint of time itself, and asking critical questions about the nature and experience of time.

Divided into six areas, including literature and language, music, psychology, sociology, history, and marking time, the collection is specific in content and broad in implication. Each article makes a contribution to scholarship within an individual discipline, and yet each transcends the bounds of discipline in its approach to broader issues involving the study of time. There is no other source like The Study of Time series that focuses so intensely on the nature and experience of time from diverse perspectives in all academic disciplines. This volume reveals the range and magnitude of intellectual endeavor in interdisciplinary research inspired by the enduring human fascination with time.

Mapping Time is an account for the general reader of the history and underlying basis of each of the most important calendars of the world, from antiquity to modern times.Containing chapters on the nature of calendars and on their astronomical background, on the history of writing and counting, on the week, and on the history of calendar reform, this fascinating and highly entertaining book is the perfect guide to understanding the background of time in the run up to the Millennium.

With the advent of the new millennium, the notion of the future, and of time in general, has taken on greater significance in postmodern thought. Although the equally pervasive and abstract concept of space has generated a vast body of disciplines, time, and the related idea of "becoming" (transforming, mutating, and metamorphosing) have until now received little theoretical attention. This volume explores the ontological, epistemic, and political implications of rethinking time as a dynamic and irreversible force. Drawing on ideas from the natural sciences, as well as from literature, philosophy, politics, and cultural analyses, its authors seek to stimulate further research in both the sciences and the humanities which highlights the temporal foundations of matter and culture.The first section of the volume, "The Becoming of the World," provides a broad introduction to the concepts of time. The second section, "Knowing and Doing Otherwise," addresses the forces within cultural and intellectual practices which produce various becomings and new futures. It also analyzes how alternative models of subjectivity and corporeality may be generated through different conceptions of time. "Global Futures," the third section, considers the possibilities for the social, political, and cultural transformation of individuals and nations.

The adventure spans the world from Stonehenge to astronomically aligned pyramids at Giza, from Mayan observatories at Chichen Itza to the atomic clock in Washington, the world's official timekeeper since the 1960s. We visit cultures from Vedic India and Cleopatra's Egypt to Byzantium and the Elizabethan court; and meet an impressive cast of historic personages from Julius Caesar to Omar Khayyam, and giants of science from Galileo and Copernicus to Stephen Hawking. Our present calendar system predates the invention of the telescope, the mechanical clock, and the concept ol zero and its development is one of the great untold stories of science and history.

How did Pope Gregory set right a calendar which was in error by at least ten lull days? What did time mean to a farmer on the Rhine in 800 A.D.? What was daily life like in the Middle Ages, when the general population reckoned births and marriages by seasons, wars, kings'' reigns, and saints' days? In short, how did the world

From the patristic age until the Gregorian calendar reform of 1582, computus -- the science of time reckoning and art of calendar construction -- was a matter of intense concern. Bede's The Reckoning of Time (De temporum ratione) was the first comprehensive treatise on this subject and the model and reference for all subsequent teaching discussion and criticism of the Christian calendar. It is a systematic exposition of the Julian solar calendar and the Paschal table of Dionysius Exiguus, with their related formulae for calculating dates. But it is more than a technical handbook. Bede sets calendar lore within a broad scientific framework and a coherent Christian concept of time, and incorporates themes as diverse as the theory of tides and the doctrine of the millennium.

This translation of the full text of The Reckoning of Time includes an extensive historical introduction and a chapter-by-chapter commentary. It will interest historians of medieval science, theology, and education, Bede scholars and Anglo-Saxonists, liturgists, and Church historians. It will also serve as an accessible introduction to computus itself. Generations of medieval computists nourished their expertise in Bede's orderly presentation; modern scholars in quest of safe passage through this complex terrain can hope for no better guide.

For over two and a half millennia human beings have attempted to invent strategies to "discover" the truth of time, to determine whether time is infinite, whether eternity is the infinite duration of a continuous present, or whether it too rises and falls with the cycles of universal creation and destruction. Time-Fetishes recounts the history of a tradition that runs counter to the dominant tradition in Western metaphysics, which has sought to purify eternity of its temporal character. From the pre-Socratics to Ovid and Plotinus, and from Shakespeare to Hegel, Schelling, Nietzsche, Heidegger, and Derrida, Time-Fetishes traces the secret tradition of the idea of eternal recurrence and situates it as the grounding thought of Western philosophy and literature. The thinkers in this counter-history of the eternal return lingered long enough on the question of time to learn how to resist separating eternity from time, and how to reflect on the possible identity of time and eternity as a way of resisting all prior metaphysical determinations. Drawing out the implications of Nietzsche's reinvention of the doctrine of return, Lukacher ranges across a broad spectrum of ancient and modern thinkers. Shakespeare's role in this history as the "poet of time" is particularly significant, for not only does Shakespeare reactivate the pre-Christian arguments of eternal return, he regards them, and all arguments and images concerning the essence of time and Being, from an inimitably ironic perspective. As he makes transitions from literature to philosophy and psychoanalysis, Lukacher displays a theoretical imagination and historical vision that bring to the forefront a host of pre- and post-Christian texts in order to decipher in them an encounter with the thought of eternal recurrence that has been too long buried under layers of rigid metaphysical interpretation.

Time flies like an arrow, but fruit flies like a banana. The Beatles learn to be brilliant in an hour and a half. An Englishman arrives back from Calcutta but refuses to adjust his watch. Beethoven has his symphonic wishes ignored. A US Senator begins a speech that will last for 25 hours. The horrors of war are frozen at the click of a camera. A woman designs a ten-hour clock and reinvents the calendar. Roger Bannister lives out the same four minutes over a lifetime. And a prince attempts to stop time in its tracks. Timekeepers is a book about our obsession with time and our desire to measure it, control it, sell it, film it, perform it, immortalise it and make it meaningful. It has two simple intentions: to tell some illuminating stories, and to ask whether we have all gone completely nuts.

In this second English-language edition of one of his most notable works, Miguel Leon-Portilla explores the Maya Indians' remarkable concepts of time. At the book's first appearance Evon Z. Vogt, Curator of Middle American Ethnology in Harvard University, predicted that it would become "a classic in anthropology," a prediction borne out by the continuing critical attention given to it by leading scholars.

Like no other people in history, the ancient Maya were obsessed by the study of time. Their sages framed its cycles with tireless exactitude. Yet their preoccupation with time was not limited to calendrics; it was a central trait in their evolving culture.

In this absorbing work Leon-Portilla probes the question, What did time really mean for the ancient Maya in terms of their mythology, religious thought, worldview, and everyday life? In his analysis of key Maya texts and computations, he reveals one of the most elaborate attempts of the human mind to penetrate the secrets of existence.

Our Own Time retells the history of American labor by focusing on the politics of time and the movements for a shorter working day. It argues that the length of the working day has been the central issue for the American labor movement during its most vigorous periods of activity, uniting workers along lines of craft, gender and ethnicity. The authors hold that the workweek is likely again to take on increased significance as workers face the choice between a society based on free time and one based on alienated work and employment.

What is the origin of the universe? What was there before the universe appeared? We are currently witnessing a second Copernican revolution: neither our Earth and Sun, nor our galaxy, nor even our universe, are the end of all things. Beyond our world, in an endless multiverse, are innumerable other universes, coming and going, like ours or different. Fourteen billion years ago, one of the many bubbles constantly appearing and vanishing in the multiverse exploded to form our universe. The energy liberated in the explosion provided the basis for all the matter our universe now contains. But how could this hot, primordial plasma eventually produce the complex structure of our present world? Does not order eventually always lead to disorder, to an increase of entropy? Modern cosmology is beginning to find out how it all came about and where it all might lead. Before Time Began tells that story.

Humanists, scientists, and artists collaborate to address the disjunctive temporalities of ecological crisis  In 2016, Antarctica’s Totten Glacier, formed some 34 million years ago, detached from its bedrock, melted from the bottom by warming ocean waters. For the editors of Timescales, this event captures the disjunctive temporalities of our era’s—the Anthropocene’s—ecological crises: the rapid and accelerating degradation of our planet’s life-supporting environment established slowly over millennia. They contend that, to represent and respond to these crises (i.e., climate change, rising sea levels, ocean acidification, species extinction, and biodiversity loss) requires reframing time itself, making more visible the relationship between past, present, and future, and between a human life span and the planet’s.  Timescales’ collection of lively and thought-provoking essays puts oceanographers, geophysicists, geologists, and anthropologists into conversation with literary scholars, art historians, and archaeologists. Together forging new intellectual spaces, they explore the relationship between geological deep time and historical particularity, between ecological crises and cultural expression, between environmental policy and social constructions, between restoration ecology and future imaginaries, and between constructive pessimism and radical (and actionable) hope. Interspersed among these essays are three complementary “etudes,� in which artists describe experimental works that explore the various timescales of ecological crisis.
