The use of various types of wave energy is an increasingly promising, non-destructive means of detecting objects and of diagnosing the properties of quite complicated materials. An analysis of this technique requires an understanding of how waves evolve in the medium of interest and how they are scattered by inhomogeneities in the medium. These scattering phenomena can be thought of as arising from some perturbation of a given, known system and they are analysed by developing a scattering theory.

In the rough-hewn America of 1827, it took a persistent kind of fellow to mine the gold said to be rushing through the land. And, it took an even more fearless brand of man to hang onto it. That icon of the Old West was Thomas L. "Peg Leg" Smith. Now the novella Temecula Color: Secrets of the Emigrant Trail by author Gary Robert Weidman spins a yarn as colorful and authentic as the rambling, vibrant character who inspired it. It's a high-flying, rollicking Western historical mystery that will keep young and older readers alike gripped by Smith's tenacity and chuckling at his derring-do and...
