Book Description

This title gives students a good understanding of how quantum mechanics describes the material world. The text stresses the continuity between the quantum world and the classical world, which is merely an approximation to the quantum world.







Wild Swans


Book Description

The story of three generations in twentieth-century China that blends the intimacy of memoir and the panoramic sweep of eyewitness history—a bestselling classic in thirty languages with more than ten million copies sold around the world, now with a new introduction from the author. An engrossing record of Mao’s impact on China, an unusual window on the female experience in the modern world, and an inspiring tale of courage and love, Jung Chang describes the extraordinary lives and experiences of her family members: her grandmother, a warlord’s concubine; her mother’s struggles as a young idealistic Communist; and her parents’ experience as members of the Communist elite and their ordeal during the Cultural Revolution. Chang was a Red Guard briefly at the age of fourteen, then worked as a peasant, a “barefoot doctor,” a steelworker, and an electrician. As the story of each generation unfolds, Chang captures in gripping, moving—and ultimately uplifting—detail the cycles of violent drama visited on her own family and millions of others caught in the whirlwind of history.




Fundamentals of Electric Propulsion


Book Description

Throughout most of the twentieth century, electric propulsion was considered the technology of the future. Now, the future has arrived. This important new book explains the fundamentals of electric propulsion for spacecraft and describes in detail the physics and characteristics of the two major electric thrusters in use today, ion and Hall thrusters. The authors provide an introduction to plasma physics in order to allow readers to understand the models and derivations used in determining electric thruster performance. They then go on to present detailed explanations of: Thruster principles Ion thruster plasma generators and accelerator grids Hollow cathodes Hall thrusters Ion and Hall thruster plumes Flight ion and Hall thrusters Based largely on research and development performed at the Jet Propulsion Laboratory (JPL) and complemented with scores of tables, figures, homework problems, and references, Fundamentals of Electric Propulsion: Ion and Hall Thrusters is an indispensable textbook for advanced undergraduate and graduate students who are preparing to enter the aerospace industry. It also serves as an equally valuable resource for professional engineers already at work in the field.
