Bøker av Michael M. Woolfson

In this 1995 book, all of the techniques available for analysing crystal structures are described at a professional level. These techniques are applied in molecular biology, chemistry, physics, mineralogy, and metallurgy. The fundamental physics and the mathematical analyses are fully explained.

A textbook for the advanced undergraduate or graduate student beginning a serious study of X-ray crystallography. It will be of interest both to those intending to become professional crystallographers and to those physicists, chemists, biologists, geologists, metallurgists and others who will use it as a tool in their research. All major aspects of crystallography are covered - the geometry of crystals and their symmetry, theoretical and practical aspects of diffracting X-rays by crystals and how the data may be analysed to find the symmetry of the crystal and its structure. Recent advances are fully covered, including the synchrotron as a source of X-rays, methods of solving structures from power data and the full range of techniques for solving structures from single-crystal data. A suite of computer programs is provided for carrying out many operations of data-processing and solving crystal structures - including by direct methods. While these are limited to two dimensions they fully illustrate the characteristics of three-dimensional work. These programs are required for many of the examples given at the end of each chapter but may also be used to create new examples by which students can test themselves or each other.

Describes historical (pre-1950) theories about solar system and illustrates why they became unacceptable. This book also critically examines extant theories, including the solar nebula theory, to determine how well they fit with accepted scientific principles and observations.
