Book Description

Dreams of time travel have long haunted the human imagination. Many physicists and philosophers think that time travel is impossible; others, such as Stephen Hawking, ponder whether perhaps it could be done. Part One of this book offers a nontechnical account of some of the major current theories concerned with time travel and with the quantum mind. The mind already makes imaginary journeys in time. The mind may some day, through a special process of information transfer, make real ones. In Part Two, the reader goes on several trial-run trips in time with great writers and filmmakers as guides. ... Read more

Book Description

This book brings together new essays on a major focus of debate in contemporary metaphysics: does time really pass, or is our ordinary experience of time as consisting of past, present, and future an illusion? The international contributors broaden this debate by demonstrating the importance of questions about the nature of time for philosophical issues in ethics, aesthetics, psychology, science, religion, and language. ...

GMDSS Reference Book
Excellent reference book for GMDSS system. Also used as a text book at the California Maritime Academy (for those of you wondering if this is the book he wants you to get).

Great General Reference on Subject
This is about the best general reference out there on the subject of GMDSS. The only drawback to the text is that it is SOMEWHAT dated, but that is because it is a text on electronics, and became dated on it's way to the printers. Still, if you need info on GMDSS, this is where to go. It is currently used as a textbook for the GMDSS course at Great Lakes Maritime academy. ... Read more

Book Description

This book provides the reader with the most recent scholarly insights into the nature of time - undoubtedly one of the most profound mysteries that science has ever faced. The selected contributions are grouped into four conceptually different yet mutually cohesive chapters, carefully woven into a comprehensive whole that goes well beyond standard treatments. The subjects discussed include the fine structure of psychological time(s) and consciousness, novel algebraic geometrical and number theoretic models of time dimension, different arrows of time, time travel, EPR paradox, quantum non-locality, pregeometry, and a host of relevant epistemological and ontological issues. The book shows that research is becoming necessarily interdisciplinary and does not ignore even such delicate issues as "altered" states of consciousness, religion and metaphysics. Although focused primarily on an academic readership, the treatise can be read with profit by anyone fascinated by the enigma of time. A coherent, multidisciplinary sampling of the most up-to-date professional research on the nature of time, addressing four major themes: internal times and consciousness, mathematical approaches to the concept of time, the physicist's view of time, and integrative science's views of time. Essential reading for anyone, scientist or layperson, with a serious interest in the topic. ... Read more

Book Description

Egypt is the richest source of primary documents for the economy, society and everyday life of the late antique Mediterranean world. Its thousands of papyri provide insight into aspects and topics ignored by ancient authors. This handbook is an indispensable tool in navigating these documents, which use a host of complex systems to date legal transactions. Extensive tables and lists help the reader understand the use of consulates, the indiction cycle, eras, and dates by imperial reigns. Other formal aspects of the documents, including Christian invocations and sworn oaths, are also fully covered. ... Read more

Book Description

This comprehensive collection of calendars could only have been assembled by the authors of the definitive text on calendar algorithms, Calendrical Calculations. Using the algorithms outlined in their earlier book, Reingold and Dershowitz have achieved the near impossible task of simultaneously displaying the date on thirteen different calendars over a three-hundred year period. Represented here are the Gregorian, ISO, Hebrew, Chinese, Coptic, Ethiopic, Persian, Hindu lunar, Hindu solar, and Islamic calendars; another three are easily obtained from the tables with minimal arithmetic (JD, R.D., and Julian). The tables also include phases of the moon, dates of solstices and equinoxes, and religious and other special holidays for all the calendars shown. These beautifully-produced tables will be of use for centuries by anyone with an interest in calendars and the societies that produce them. ... Read more

The Perfect Companion to "Calendrcal Calculations"
Whether you have enjoyed the previous book "Calendrical Calculations : The Millenium Edition", or you do not care for that book's theory, you'll love this one because you get to see the results, laid out in clean crisp typography, with many small details (holidays, moon phases, ...) that make this book a pleasure to use as a reference. Well worth the price. ... Read more

Book Description

Benjamin Franklin conceived of it. Sir Arthur Conan Doyle endorsed it. Winston Churchill campaigned for it. Kaiser Wilhelm first employed it. Woodrow Wilson and Franklin Roosevelt went to war with it, and more recently the United States fought an energy crisis with it. For several months every year, for better or worse, daylight savings time affects vast numbers of people throughout the world. And from Ben Franklin's era to today, its story has been an intriguing and sometimes-bizarre amalgam of colorful personalities and serious technical issues, purported costs and perceived benefits, conflicts between interest groups and government policymakers. It impacts diverse and unexpected areas, including agricultural practices, street crime, the reporting of sports scores, traffic accidents, the inheritance rights of twins, and voter turnout. Illustrated with a popular look at science and history, Seize the Daylight presents an intriguing and surprisingly entertaining story of our attempt to regulate the sunlight hours. ... Read more

Book Description

Newton, Einstein…now Stewart swells their ranks with The Special Theory of Relative Time (plural): The Presence in the Quantum World…enter Quantum, Classical and Love-Time…gravity has been conquered.

Stewart covers a diverse range of topics including:

Physica section

• How Quantum and Classical-Time apply themselves in the subatomic domain through spontaneous interactions.
• That Quantum-Time causes finite oscillations to occur…that is fluctuations between particle form and waveform.
• The glutinous jelly-like diamond twisted cubes of gravitation and the mobility role of the so-called human aura.

Metaphysica section

• Women have a waking Quantum-mind with a Classical unconscious whilst men have a waking Classical-mind with a Quantum unconscious.
• Love-Time’s production of the neutrino’s that serves as the prayer particle, the emotion particle, the E.S.P particle and the love particle.

The Pigeon-Toed Orange Peel section

• Serves to detail one or two of the amazing coincidences that have occurred along my journey and that fly in the face of all probability.

Book Description

For this third edition H. D. Zeh has thoroughly revised his book to include important new results. At the same time it retains the features that make it a classic text on irreversibility, and one which clearly distinguishes the latter from time asymmetry. New findings are presented particularly in the chapters on the arrow of time in quantum mechanics and quantum cosmology. Concepts such as decoherence and timelessness are discussed. The book has gained a reputation for its thorough survey of what is known about irreversibility in physics. It investigates physical phenomena in classical, quantum and cosmological settings. Both physicists and philosophers of science who reviewed earlier editions considered this book a magnificent survey, a concise, technically sophisticated, up-to-date discussion of the subject, showing fine sensitivity to some of the crucial philosophical subtleties. ...

THE place to look for the physics behind the arrow of time
A lot has been written about the arrow of time, a large amount of which leaves out the details (such as Huw Price's recent book). For those details, this is THE place to look. Those discussing the arrow of time, whether they agree or disagree with his conclusions, generally start with what has been written down here.

In this slim volume, Zeh gives a wonderfully concise and broad coverage to all physical aspects of the arrow of time. Furthermore, while his approach is rigorous, he makes a point of drawing out what the mathematical conclusions mean, and he does so quite lucidly. As a bonus he has a wonderful section on the quanticization of time. The only problem with this book is the rather high price tag, which will probably stop most of the casual readers interested in the topic from picking up a copy. ... Read more

Book Description

From the author of the bestselling "Analysis of Time Series," Time-Series Forecastingoffers a comprehensive, up-to-date review of forecasting methods. It provides a summary of time-series modelling procedures, followed by a brief catalogue of many different time-series forecasting methods, ranging from ad-hoc methods through ARIMA and state-space modelling to multivariate methods and including recent arrivals, such as GARCH models, neural networks, and cointegrated models. The author compares the more important methods in terms of their theoretical inter-relationships and their practical merits. He also considers two other general forecasting topics that have been somewhat neglected in the literature: the computation of prediction intervals and the effect of model uncertainty on forecast accuracy.Although the search for a "best" method continues, it is now well established that no single method will outperform all other methods in all situations-the context is crucial. Time-Series Forecasting provides an outstanding reference source for the more generally applicable methods particularly useful to researchers and practitioners in forecasting in the areas of economics, government, industry, and commerce. ...

Book Description

Is time, even locally, like the real line? Multiple structures of time, implicit in physics, create a consistency problem. A tilt in the arrow of time is suggested as the most conservative hypothesis which provides approximate consistency within physics and with topology of mundane time.Mathematically, the assumed constancy of the velocity of light (needed to measure time) implies functional differential equations of motion, that have both retarded and advanced deviating arguments with the hypothesis of a tilt. The novel features of such equations lead to a nontrivial structure of time and quantum-mechanical behaviour. The entire argument is embedded in a pedagogical exposition which amplifies, corrects, and questions the conventionally accepted approach. The exposition includes historical details and explains, for instance, why the entropy law is inadequate for time asymmetry, and why notions such as time asymmetry (hence causality) may be conceptually inadequate.The first three parts of the book are especially suited as supplementary reading material for undergraduate and graduate students and teachers of physics. The new ideas are addressed to researchers in physics and philosophy of science concerned with relativity and the interpretation of quantum mechanics. ... Read more
