Book Description
This book gives an account of certain observed irregularities on the rotation of the Earth, both in its rate of rotation (giving a variable length of day) and in the position of its axis. These irregularities are caused by events on and within the Earth and provide a means of studying a number of geophysical problems. Seasonal shifts in air masses and variable winds are causes of short-period fluctuations in the rotation. Climatic changes and their attendant sea levels are in part responsible for long-term fluctuations. Modern observations of the Moon and descriptions of ancient elipses both establish a secular increase in the length of day. The interpretation involves atmospheric, oceanic and bodily tides. The book provides a unified treatment of the rotation of the Earth, making this method of studying geophysical phenomena more readily accessible to geophysicists and others.

Book Description
IAU Symposium No. 82, "Time and the Earth's Rotation", met to discuss modern research in the field of the rotation of the Earth with particu lar emphasis on the role of new observational techniques in this work. The use of these techniques has prompted a new look at the definitions of the traditional reference systems and the concepts of the rotation of the Earth around its center of mass. Specific topics discussed were time, polar motion, reference systems, conventional radio interferometry, very'long baseline interferometry (VLBI), Doppler satellite methods, satellite laser ranging, lunar laser ranging, and geophysical research concerning the Earth's rotation. Improvement in the accuracy of the observations is a key to possible solutions of the many unsolved problems remaining in this field. It appears that such improvement, using both classical and new techniques, is forthcoming in the near future. This will surely contribute to a better understanding of some of the long-standing questions concerning the rotation of the Earth around its center of mass and lead to an improved knowledge of the rotating, deformable Earth. This volume contains the papers presented at IAU Symposium No. 82 as well as the discussions provoked by these papers. It is hoped that it captures the principal points of the meeting and that it will contribute not only to a better understanding of existing problems, but also to future research in time and the Earth's rotation.

Book Description
This book is intended for geophysicists, astronomers (especially those with an interest in history), historians and orientalists. The culmination of many years of research, it discusses, in depth, ancient and medieval eclipse observations and their importance in studying Earth's past rotation. This was the first major book on this subject to appear in the last twenty years. The author has specialised in the interpretation of early astronomical records and their application to problems in modern astronomy for many years. The book contains an in-depth discussion of numerous eclipse records from Babylon, China, Europe and the Arab lands. Translations of almost every record studied are given. It is shown that although tides play a dominant long-term role in producing variations in Earth's rate of rotation - causing a gradual increase in the length of the day - there are significant, and variable non-tidal changes in opposition to the main trend.

Book Description
Long before Galileo published his discoveries about Jupiter, lunar craters, and the Milky Way in the Starry Messenger in 1610, people were fascinated with the planets and stars around them. That interest continues today, and scientists are making new discoveries at an astounding rate. Ancient lake beds on Mars, robotic spacecraft missions, and new definitions of planets now dominate the news. How can you take it all in? Start with the new Encyclopedia of the Solar System, Second Edition.This self-contained reference follows the trail blazed by the bestselling first edition. It provides a framework for understanding the origin and evolution of the solar system, historical discoveries, and details about planetary bodies and how they interact—and has jumped light years ahead in terms of new information and visual impact. Offering more than 50% new material, the Encyclopedia includes the latest explorations and observations, hundreds of new color digital images and illustrations, and more than 1,000 pages. It stands alone as the definitive work in this field, and will serve as a modern messenger of scientific discovery and provide a look into the future of our solar system.· Forty-seven chapters from 75+ eminent authors review fundamental topics as well as new models, theories, and discussions· Each entry is detailed and scientifically rigorous, yet accessible to undergraduate students and amateur astronomers· More than 700 full-color digital images and diagrams from current space missions and observatories amplify the chapters· Thematic chapters provide up-to-date coverage, including a discussion on the new International Astronomical Union (IAU) vote on the definition of a planet· Information is easily accessible with numerous cross-references and a full glossary and index

Book Description
This volume reviews the cumulative evidence suggesting that a connection may exist between the Earth's rotation and geotectonics. Among other benefits, such a connection may assist in deciphering the flow of the Earth's mantle.

Book Description
NAMED ONE OF THE BEST BOOKS OF THE YEAR BY People ∙ O: The Oprah Magazine ∙ Financial Times ∙ Kansas City Star ∙ BookPage ∙ Kirkus Reviews ∙ Publishers Weekly ∙ Booklist NEW YORK TIMES BESTSELLER “A stunner.”—Justin Cronin “It’s never the disasters you see coming that finally come to pass—it’s the ones you don’t expect at all,” says Julia, in this spellbinding novel of catastrophe and survival by a superb new writer. Luminous, suspenseful, unforgettable, The Age of Miracles tells the haunting and beautiful story of Julia and her family as they struggle to live in a time of extraordinary change. On an ordinary Saturday in a California suburb, Julia awakes to discover that something has happened to the rotation of the earth. The days and nights are growing longer and longer; gravity is affected; the birds, the tides, human behavior, and cosmic rhythms are thrown into disarray. In a world that seems filled with danger and loss, Julia also must face surprising developments in herself, and in her personal world—divisions widening between her parents, strange behavior by her friends, the pain and vulnerability of first love, a growing sense of isolation, and a surprising, rebellious new strength. With crystalline prose and the indelible magic of a born storyteller, Karen Thompson Walker gives us a breathtaking portrait of people finding ways to go on in an ever-evolving world. “Gripping drama . . . flawlessly written; it could be the most assured debut by an American writer since Jennifer Egan’s Emerald City.”—The Denver Post “Pure magnificence.”—Nathan Englander “Provides solace with its wisdom, compassion, and elegance.”—Curtis Sittenfeld “Riveting, heartbreaking, profoundly moving.”—Kirkus Reviews (starred review) Look for special features inside.

Book Description
Filling an important gap in the geophysical literature at specialist level, this monograph is the only up-to-date title to provide a link between the Earth's rotation and its atmo- and hydrosphere, including the ice masses. Starting with the Earth's motions, the text goes on to look at irregularities and the effect of atmospheric processes on the Earth's spin. Tides and seasons occupy the following sections before a discussion of the Earth-ocean-atmosphere system and the mechanical action of the atmosphere on the Earth's rotation. The whole is rounded off by an index of abbreviations and appendices with sections on related physics for better readability, plus a comprehensive bibliography for further reading. A must for geophysicists, oceanographers, glaciologists, climatologists and meteorologists alike.
