Sommario/riassunto

Capturing the vitality of California's unique indigenous cultures, this major new introduction incorporates the extensive research of the past thirty years into an illuminating, comprehensive synthesis for a wide audience. Based in part on new archaeological findings, it tells how the California Indians lived in vibrant polities, each boasting a rich village life including chiefs, religious specialists, master craftspeople, dances, feasts, and ceremonies. Throughout, the book emphasizes how these



diverse communities interacted with the state's varied landscape, enhancing its already bountiful natural resources through various practices centered around prescribed burning. A handy reference section, illustrated with more than one hundred color photographs, describes the plants, animals, and minerals the California Indians used for food, basketry and cordage, medicine, and more. At a time when we are grappling with the problems of maintaining habitat diversity and sustainable economies, we find that these native peoples and their traditions have much to teach us about the future, as well as the past, of California.

Sommario/riassunto

Essential Spaceflight Dynamics and Magnetospherics describes, in the first instance, some of the key aspects of celestial mechanics and spaceflight dynamics. It begins with classical two and three body problems illustrative of the aesthetic aspects of applying analytical methods of investigation to celestial mechanics. Then, osculating orbital elements are introduced as well as analysis techniques sufficient to evaluate the influence of various disturbing forces on spacecraft. Next a theory of manoeuvres is outlined and the methodology of making interplanetary trajectory corrections. Ideas involving various approaches to orbital element determinations using measured data are also considered. The forces applied to a spacecraft can result in the development of torques that influence attitude motion and the effects of the most important of these are described in terms of equilibrium positions, periodic motions, steady-state and transient motions. Also considered is the problem of attitude control of a spacecraft using active and/or passive methods of orientation and stabilization. In addition, a more advanced treatment of the development of attitude control systems is provided.
