Sommario/riassunto

This invaluable book contains pedagogical articles on the dominant nonstochastic methods of microscopic many-body theories - the methods of density functional theory, coupled cluster theory, and correlated basis functions - in their widest sense. Other articles introduce students to applications of these methods in front-line research, such as Bose-Einstein condensates, the nuclear many-body problem, and the dynamics of quantum liquids. These keynote articles are supplemented by experimental reviews on intimately connected topics that are of current relevance. The book addresses the striking

Sommario/riassunto

Gunther Kress argues for a radical reappraisal of the phenomenon of literacy, and hence for a profound shift in educational practice. Through close attention to the variety of objects which children constantly produce (drawings, cuttings-out, 'writings' and collages), Kress suggests a set of principles which reveal the underlying coherence of children's actions; actions which allow us to connect them with attempts to make meaning before they acquire language and
