The theory of the chemical interaction of molecules with surfaces has advanced handsomely in the last few years. This is due in part to the application of the entire arsenal of bulk solid-state theory and molecular quantum chemistry methods. This considerable activity was stimulated by an outpouring of experimental data, particularly of photoemission spectra. In many cases the theoretical techniques are now such that accurate, atomistic pictures of chemisorption phenomena are computed from first principles. This level of capability has been reached only recently, and has not been described anywhere in a comprehensive manner. The purpose of this monograph is to review these recent advances and, at the same time, to indicate a number of important questions which have not been answered. We discuss chemisorption on oxides, semiconductors, and both simple and transition metals. Solid surfaces as well as clusters are considered. While the review should be valuable to workers in the field, care has been taken to make the chapters understandable to the nonspecialist.

ThiS is not only a book of instruction in chainmaking but it is also a work celebrating man's continuous creativity over thousands of years. At times something that man creates has far-reach ing effects; an example that quickly comes to mind is the wheel, which has enabled many devel opments, from pottery to computers. At this point it is important to note that these same wheels could not have been made without metal tools. From early Neolithic times on gold was a favorite choice in the making of jewelry. During the Neolithic period these "shining stones," probably alluvial, were prized. Actually gold was cold worked as if it were a stone. There is a surviving example of cold-worked gold from Catahuyuk (present day Turkey) estimated to have been made in 6500 B. C. There were only four metals on the earth's surface that were found in sufficient quantity to be used: gold, copper, silver, and meteoric iron. An understanding of the malleability of gold, and of the annealing effect of fire, changed jewelry making; new forms were found. Gold was no longer a piece of stone but a material that could be flattened and made very thin. Sheet and foil are the oldest forms of worked gold. The smiths' tools were stone, wood, and horn."

Coal is a black dog who lives on an island in Michigan. She and her island friends are curious and adventurous but they don't always make the right choices. Join Coal as she explores her island, meets new people and learns some important lessons.

The Gunsmith's old friend, Bill Hickok, controls Abilene, Kansas with a tight fist and a fast gun, brooking challenge by no man. But even the legendary Wild Bill needs a hand when the James brothers, John Wesley Hardin, Phil Coe, and Ben Thompson converge on the town at once. Clint Adams takes Hickok's side-but not before a sexy lady saloonkeeper gets into the act, and into The Gunsmith's bed. She does her level best to make him stay on for good. But Adams is too busy dodging bullets and backing up Wild Bill to let a woman tie him down.

Geodesy made easy—an accessible introduction to a rapidly changing field

Geodesy is the science that deals with the earth's figure and the interrelationship of selected points on its surface. This user-friendly introduction presents what might be called "geodesy without mathematics." A revised edition of the author's Basic Geodesy, Introduction to Geodesy avoids complex formulas and equations and provides a broad overview for students and professionals who require a basic understanding of the subject.

Topics include:

• Traditional survey positioning techniques
• Geodetic systems, including horizontal and vertical geodetic datums
• Physical geodesy
• The world geodetic system
• Satellite geodesy
• The Global Positioning System
• Gravity measures
• Electromagnetic distance measurement
• Projections
• Examples of modern projects.
