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
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 Erratic Planet is a book of vital importance to the future of our species. Drawing on a staggering range of references across disciplines including geology, astronomy, archaeology and palaeontology, Ian Rankin' outlines his radical ideas about the worlds past. Contrary to conventional scientific thinking, the evidence he has examined has convinced him that the history of our planet is not one of gradual change, as proposed by Darwin's theory of evolution, but a story of successive, yet systematic, global catastrophes. These have wiped almost all trace of previous civilisations from the face of the Earth. These catastrophes, known as pole shifts, derive from the unstable nature of the solar system, which is the subject of the book's second part.

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
The past few decades have witnessed the growth of the Earth Sciences in the pursuit of knowledge and understanding of the planet that we live on. This development addresses the challenging endeavor to enrich human lives with the bounties of Nature as well as to preserve the planet for the generations to come. Solid Earth Geophysics aspires to define and quantify the internal structure and processes of the Earth in terms of the principles of physics and forms the intrinsic framework, which other allied disciplines utilize for more specific investigations. The first edition of the Encyclopedia of Solid Earth Geophysics was published in 1989 by Van Nostrand Reinhold publishing company. More than two decades later, this new volume, edited by Prof. Harsh K. Gupta, represents a thoroughly revised and expanded reference work. It brings together more than 200 articles covering established and new concepts of Geophysics across the various sub-disciplines such as Gravity, Geodesy, Geomagnetism, Seismology, Seismics, Deep Earth Processes, Plate Tectonics, Thermal Domains, Computational Methods, etc. in a systematic and consistent format and standard. It is an authoritative and current reference source with extraordinary width of scope. It draws its unique strength from the expert contributions of editors and authors across the globe.

Book Description
The family from Secrets of the Garden are back in a new book about backyard science that explains why the seasons change. Alice and her friend Zack explore the reasons for the seasons. Alice's narrative is all about noticing the changes as fall turns into winter, spring, and then summer. She explains how the earth's yearlong journey around the sun, combined with the tilt in the earth's axis, makes the seasons happen. Alice's text is clear and simple, and experiential. Two very helpful—and very funny—chickens give more science details and further explanation through charts, diagrams, and sidebars. Packed with sensory details, humor, and solid science, this book makes a complicated concept completely clear for young readers—and also for the many parents who struggle to answer their kids' questions! "Several adults of my acquaintance . . . would find Secrets of the Seasons to be an eye-popping revelation." —John Lithgow, The New York Times Book Review
