Pressestimmen

"Each of the six chapters holds the reader's attention. The material, which is presented on the level of an advanced undergraduate, should pique the interest of novices with a science background; advanced practitioners may be reminded of forgotten aspects of the subject . . . .The book's greatest asset is that it assembles such a marvelous group of authors."--"American Scientist"
