For a thorough comprehension of the field of geophysics, we need to understand its origins. Basic Geophysics by Enders Robinson and Dean Clark takes us on a journey that demonstrates how the achievements of our predecessors have paved the way for our modern science. From the ancient Greeks through the Enlightenment to the greats of the contemporary age, the reasoning behind basic principles is explored and clarified. With that foundation, several advanced topics are examined, including: the 3D wave equation; ray tracing and seismic modeling; reflection, refraction, and diffraction; and WKBJ migration. The successful integration of the historical narrative alongside practical analysis of relevant principles makes this book an excellent resource for both novices and professionals, and all readers will gain insight and appreciation for the seismic theory that underlies modern exploration seismology.
Addresses the construction, analysis, and interpretation of mathematical and statistical models. The practical use of the concepts and techniques developed is illustrated by numerous applications. The chosen examples will interest many readers, including those engaged in digital signal analysis in disciplines other than geophysics.
Covering ideas and methods while concentrating on fundamentals, this book includes wave motion; digital imaging; digital filtering; visualization aspects of the seismic reflection method; sampling theory; the frequency spectrum; synthetic seismograms; wavelet processing; deconvolution; seismic attributes; phase rotation; and seismic attenuation.
A detailed and highly readable account of the Salem witchcraft affair of 1692 in three parts. R0515HB - $32.50
Focusing on the basic theory required to solve practical problems, this book provides 212 problems, and solutions, which cover a wide range of issues, including least-squares methods, choosing velocities for various situations, z-transforms, determining 2D and 3D field geometries, and solving processing and interpretation problems.
Overview: The Salem witch hunt of 1692 represents one of the grimmest events in early American history. It is the story of innocent people caught in a web of intrigue from which they could not extricate themselves. The author, himself a descendant of one of those executed, argues masterfully that the witch hunt was driven by conspiracies of envious men intent on destroying their enemies. Sanctioned by the old guard of Puritan leaders, these men arrested two hundred people for witchcraft, twenty-eight of whom were executed or died in prison. The convergence of religious, social, political, and economic forces that sparked the accusations and trials are laid out clearly and concisely, exploring the motives and relationships of those who fanned the flames of the witch hunt. Robinson also provides a closer look at the lives of seventy-five of the people accused as witches, analyzing their places in the community and shedding light on why they were targeted.
