دانلود کتاب The world according to quantum mechanics : why the laws of physics make perfect sense after all

The book summarises contemporary knowledge about the theory of atomic and molecular clusters. New results are discussed on a high theoretical level. Access to this field of research is given by an explanation of the various subjects in introductory chapters An invaluable supplement to standard textbooks on quantum mechanics, this introduction to the general theoretical framework of contemporary physics focuses on conceptual, epistemological, and ontological issues.
