This book deals with the electron density distribution in molecules and solids as obtained experimentally by X-ray diffraction. It is a comprehensive treatment of the methods involved, and the interpretation of the experimental results in terms of chemical bonding and intermolecular interactions. Inorganic and organic solids, as well as metals, are covered in the chapters dealing with specific systems. As a whole, this monograph is especially appealing because of its broad interface with numerous disciplines. Accurate X-ray diffraction intensities contain fundamental information on the charge...

This is the first book to cover the new landscape of pyramids found worldwide. It describes the changed nature of the pyramid debate and offers science a challenge, but equally tries to answer some of the key messages that the last decade of pyramid discovery has brought us. It is a series of discoveries that has changed the archaeological world and extended all our horizons.

Years of research has unveiled that the Grail account describes the events of a specific timeframe, 1104 to 1137, in a specific location: the royal court of Aragon (northern Spain). This book identifies both the historical figures on which the protagonists of the Grail story is based and the identity of the Grail itself.

This book represents the proceedings of a symposium held at the Spring 1981 ACS meeting in Atlanta. The symposium brought together Theoretical Chemists, Solid State Physicists, Experimen tal Chemists and Crystallographers. One of its major aims was to increase interaction between these diverse groups which often use very different languages to describe similar concepts. The devel opment of a common language, or at least the acquisition of a multilingual capability, is a necessity if the field is to prosper. Much depends in this field on the interplay between theory and experiment. Accordingly...
