One day, down by the pond, Simon meets another dog just like him. And that dog has a bone just like his, only better! How will Simon ever get him to trade, when the other pup knows all the same tricks? Using the same innovative format as his Caldecott Honor winner, Mel Fell, Corey R. Tabor reimagines Aesop's "The Dog and His Reflection" in a clever, charming tale of empathy and generosity.

This invaluable practical guide shows how to set up working models of telescopes, microscopes, photographic lenses and projecting systems, then shows how to conduct experiments for determining accuracy, resolving power, identifying aberration, and more. Only elementary mathematics required. Index. 234 diagrams.

Lasers play an increasingly important role in a variety of detection techniques, making inelastic light scattering a tool of growing value in the investigation of dynamic and structural problems in chemistry, biology, and physics. Until the initial publication of this work, however, no monograph treated the principles behind current developments in the field.This volume presents a comprehensive introduction to the principles underlying laser light...

A highly engaging study of mirages, illusions of multiple moons, the fata morgana, colored shadows and scores of other phenomena in a book. 202 illustrations.

This undergraduate textbook presents thorough coverage of the standard topics of classical optics and optical instrument design; it also offers significant details regarding the concepts of modern optics. Its survey of the mathematical tools of optics grants students insights into the physical principles of quantum mechanics. Two principal concepts occur throughout: a treatment of scattering from real scatterers (leading to Huygens' principles, diffraction...
