The Compendium of Practical Astronomy is unique. The practical astronomer, whether student, novice or accomplished amateur, will find this handbook the most comprehensive, up-to-date and detailed single guide to the subject available. It is based on Roth’s celebrated German language handbook for amateur astronomers, which first appeared over 40 years ago.

With amateurs and students and teachers of astronomy in high schools and colleges particularly in mind over 10 leading astronomers have worked under the careful editorship of Günter Roth to cover all aspects of practical astronomy.

During the last 30 years, seismic interpreters have routinely applied bright spot and AVO technology for recognizing prospects and predicting lithology. New amplitude attributes were added to this technology as new exploration problems were defined.

During the last 30 years, seismic interpreters have routinely applied bright spot and AVO technology for recognizing prospects and predicting lithology. New amplitude attributes were added to this technology as new exploration problems were defined. R&D continues in the field of amplitude interpretation, especially when E&P costs escalate as more severe environments are explored, such as the ultra-deepwater plays. With the high interest in reducing exploration risk, this course addresses the methodology of an amplitude interpretation and the subsequent benefits and limitations that one can expect in various rock-property settings. This book, originally produced for use with the fourth SEG/EAGE Distinguished Instructor Short Course, begins with a review of relationships between rock properties and geophysical observations. 

Practical problems illustrate the assumptions and limitations of commonly used empirical transforms, and procedures for conducting and verifying fluid-substitution techniques are presented. The book identifies components of the seismic response best suited for differentiating pore fluid from lithologic effects. Field examples emphasize what combination of seismic signatures should be expected for different rock-property environments. To help select the best seismic attribute for calibrating amplitude to rock properties, rules of thumb are provided for predicting AVO responses and interpreting lithology from observed responses. A case history is also provided. The last part examines the numerous amplitude attributes that can be extracted from seismic data to quantify an interpretation. Benefits and limitations of these attributes in soft- to hard-rock environments are discussed with model data and in case histories

A Brief History of Time

A Brief History of Time
Stephen Hawking  

Publisher: Bantam Press | edition 2001  

PDF | 101 pages | 1,3 mb

In this revised, expanded and illustrated edition of "A Brief History of Time", Stephen Hawking includes the most recent developments in the field of cosmology, many of which were forecast by himself. Explaining his complex theories through a visual dimension, the book contains illustrations and computer images of three- and four-dimensional concepts which are designed to help the lay reader to understand abstract ideas. In this way, the "big bang", "wormholes", black holes, particle physics, the vastness of intergalactic space, and matter and anti-matter are introduced.

About the Author: Stephen Hawking, who was born in 1942 on the anniversary of Galileo’s death, holds Isaac Newton’s chair as Lucasian Professor of Mathematics at the University of Cambridge. Widely regarded as the most brilliant theoretical physicist since Einstein, he is also the author of Black Holes and Baby Universes, published in 1993, as well as numerous scientific papers and books.
