The Appalachian Trail covers 14 states and over 2,000 miles, snaking through some of the most spectacular landscapes in America. Reluctant adventurer Bryson recounts his gruelling hike along the longest continuous footpath in the world

Advanced Engineering Mathematics is known for its comprehensive coverage, careful and correct mathematics, outstanding exercises, and self-contained, modular content for maximum flexibility. The new edition continues in the tradition of providing a comprehensive and up-to-date resource for teaching and learning engineering mathematics - an applies mathematics book for engineers, physicists, mathematicians and computer scientists

Unlike a course in "calculus" or "diferential equations"' where the content of the course is fairly standardized, the content of a course entitled "engineering mathematics" sometimes varies considerably between two different academic institutions. A text entitled Advanced Engineering Mathematics is therefore a compendium of many mathematical topics, all of which are loosely related by the expedient of either being needed or useful in courses and subsequent careers in science and engineering
