The fourth edition of Physics of the Earth maintains the original philosophy of this classic graduate textbook on fundamental solid earth geophysics, while being completely revised, updated, and restructured into a more modular format to make individual topics even more accessible. Building on the success of previous editions, which have served generations of students and researchers for nearly forty years, this new edition will be an invaluable resource for graduate students looking for the necessary physical and mathematical foundations to embark on their own research careers in geophysics. Several completely new chapters have been added and a series of appendices, presenting fundamental data and advanced mathematical concepts, and an extensive reference list, are provided as tools to aid readers wishing to pursue topics beyond the level of the book. Over 140 student exercises of varying levels of difficulty are also included, and full solutions are available online at www.cambridge.org/9780521873628.
This scientifically sound, yet easily readable book provides the fundamentals necessary to understand today's energy and climate problems and provides possible answers based on current technology such as solar, water and geothermal power. Moreover, it introduces the reader to new concepts that are already or may soon be realized, such as nuclear fusion or a hydrogen-based economy. Aimed at a wide readership ranging from educated laypeople and students to practitioners in engineering and environmental science.
How God Designed the Universe and Fine-Tuned It for Us and Evolution

To show from the Big Bang to the end of this universe observers and their souls are the reason for it all. How? By using published scientific facts, figures, and extrapolations from the bio-geo-chemo-physics fields of discoveries. Most of these discoveries are by the worlds top scientists and are generally accepted as facts. This book discusses how the four primary physical forces and the many fundamental constants, through their designed-in fine-tuning and governed interactions, formed the ongoing evolution of our universe. The steady flow of new scientific data and evidence since Isaac Newton has led to the Anthropic Principleits designed for us observers. The number of planets discovered in our galaxy alone, now many hundreds and increasing monthly, virtually leads to the assumption that we are not alone. Now many of those renowned cosmic discoverers publish strong personal suggestions that a super-intelligent mind, transcendent of the big bang, designed the whole works to produce observers. The singularity seems to have been a complete kit to create a universe full of inhabitable planets and observerson earth, thats us. The end product of observers everywhere is souls. Thats what God wants. The supply of hydrogen is finite, so is the universe since the stars will finally burn it all up. This, in turn, limits the number of souls produced for Gods transcendent realm of eternity. This author has discovered nothing but the designed pattern of events and their ultimate results. Read this book, assess the evidence, and you, too, will believe God did it all for his purpose.

Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 59. As part of the Nineteenth General Assembly of The International Union of Geodesy and Geophysics Symposium (IUGG) in Vancouver, Canada, Union Symposium U4, "Variations in Earth Rotation" was held August 18-19 1987. The Convenor was Dennis D. McCarthy, U.S. Naval Observatory with P. Paquet, Observatoire Royal de Belgique and M. G. Rochester, St. Johns University serving as co-convernors. In a session on internal structure of the Earth papers dealt with the geophysical effects on Earth rotation parameters. Mantle anelasticity increases the free core nutation (FCN) period by a few days. The period of the FCN and the amplitudes of the main nutation components are sensitive to the ellipticity of the core?]mantle boundary (CMB), and a non-hydrostatic increase of 400m in the flattening of the CMB is a possible explanation of the discrepancies from theory. An alternative suggestion rests on the subseismic description of the nutation spectrum of the stratified liquid core. Evidently new models will have to take into account contributions from the oceans, mantle anelasticity, non-hydrostatic pre-stress, CMB topography and internal core structure.

P.Brosche The development of the ideas and observational techniques related to the subject of our meeting "Tidal friction and the Earth's rotation", Bielefeld, September 1977 is one of the most fascinating books - not merely chapters! - of the modern history of science. Its genealogical tree is as intricate as that of mankind itself: There are dead ends and superfluous re-discoveries. Due to these circumstances and to the pure extent of the topic, it is impossible to give more than a few highlights here. The first relevant observational fact was discovered by the famous English astronomer E. Halley in 1695 (Berry, 1961). He simply could not arrive at an agreement between ancient and recent eclipses using a constant mean angular motion of the Moon. Instead, he had to intro duce an empirical acceleration term in the mean motion. Known as the "secular acceleration", it has ever since been a most challenging sub ject of celestial mechanics and a main branch of the genealogical tree already mentioned. In 1754, completely independently and almost certainly in ignorance of those specialists' activities, the German philosopher Kant established the idea of tidal friction as a decelerating mechanism for the rotation of the Earth (Felber, 1974). Although he made some errors in his rough computations, the majority of the constitutive elements of his concept have survived to the present day (Brosche, 1977).

A New Theory of the Creation and Decay of the Celestial Bodies

Pubpsher: Springer Science & Business Media
Analysis of the orbital motion of the Earth, the Moon and other planets and their satellites led to the discovery that all bodies in the Solar System are moving with the first cosmic velocity of their proto parents. The mean orbital velocity of each planet is equal to the first cosmic velocity of the Protosun, the radius of which is equal to the semi-major axis of the planet’s orbit. The same applies for the planets’ satellites. All the small planets, comets, other bodies and the Sun itself follow this law, a finding that has also been proven by astronomical observations. The theoretical solutions based on the Jacobi dynamics explain the process of the system creation and decay, as well as the nature of Kepler’s laws.
The advent of accessible student computing packages has meant that geophysics students can now easily manipulate datasets and gain first-hand modeling experience - essential in developing an intuitive understanding of the physics of the Earth. Yet to gain a more in-depth understanding of physical theory, and to develop new models and solutions, it is necessary to be able to derive the relevant equations from first principles. This compact, handy book fills a gap left by most modern geophysics textbooks, which generally do not have space to derive all of the important formulae, showing the intermediate steps. This guide presents full derivations for the classical equations of gravitation, gravity, tides, earth rotation, heat, geomagnetism and foundational seismology, illustrated with simple schematic diagrams. It supports students through the successive steps and explains the logical sequence of a derivation - facilitating self-study and helping students to tackle homework exercises and prepare for exams.
