If you've been searching for a basic text on how the atom works, this is it." --Booklist "A masterpiece."--OmniThe legendary Isaac Asimov starts what is perhaps the most fascinating of all his books with a simple query: how finely can a piece of matter be divided? But like many simple questions, this one leads us on a far-flung quest for a final answer, a search that becomes a series of beautifully structured building blocks of knowledge.It begins with the earliest speculations and investigations by the Greeks and Romans, and then, step by step and century by century, it traces the path of discovery that revealed more and more of the nature of the atom, of light, of gravity, of the electromagnetic force--and even the nature and structure of the universe.Atom also encompasses such phenomena as light and electricity; the protons, neutrons and quarks that are the fundamental units of the universe; hard-to-observe "anti-particles"; and other strange bits of matter that challenge our assumptions about the very nature of space and time.Atom is the only book of its kind, by the renowned author whose genius for bringing clarity and excitement to complex subjects has made him the most celebrated science author of our time.

    The first few chapters introduce the general principles of protein structure both for novices and for non-specialists needing a primer. Subsequent chapters use specific examples of proteins to show how they fulfill a wide variety of biological functions. The book ends with chapters on the experimental approach to determining and predicting protein structure, as well as engineering new proteins to modify their functions.

    Exercises correspond to chapters in the main text. Problems of special ease or difficulty are labeled for optional use. Workbook includes a formula index of all targ

    In this new edition, everything, including the original twelve chapters, bibliography, appendix, etc., has been clarified, updated and expanded. This edition includes updated and new information on recovery procedures and materials such as lifting, photography and casting; chemical enhancement; updated information about footwear manufacturing; footwear sizing; and known impression techniques and materials.WHAT S NEW IN THE SECOND EDITION:Besides updating and expanding the twelve original chapters, Footwear Impression Evidence: Detection, Recovery and Examination, Second Edition adds three new chapters: one chapter on barefoot evidence, which concerns impressions made by the naked or sock-clad foot or those which remain in abandoned or discarded footwear; another new chapter on several cases in which the footwear impression evidence was of primary importance in bringing about a conviction or confession; and finally, a new chapter on the footwear impression evidence in the O.J. Simpson criminal and civil cases.

    Including protective groups and techniques for formation and cleavage, the focus of the text is placed firmly upon chemical details rather than discussion.

    Ohring has contributed many highly regarded reference books to the AP list, including Reliability and Failure of Electronic Materials and the Engineering Science of Thin Films. The knowledge base is intended for science and engineering students in advanced undergraduate or first-year graduate level courses on thin films and scientists and engineers who are entering or require an overview of the field.Since 1992, when the book was first published, the field of thin films has expanded tremendously, especially with regard to technological applications. The second edition will bring the book up-to-date with regard to these advances. Most chapters have been greatly updated, and several new chapters have been added.

    It relates the history of chemicals, from the earliest generation of the light elements in the Big Bang, to their transformation into heavier atoms and their subsequent molecular evolution intomyriad forms, including life on Earth. Spanning both organic and inorganic chemical combinations, the survey thus covers billions of years and involves evidence coming from the analysis of long-extinct as well as ongoing processes. The techniques used in this fascinating study are also described.They include the analysis of many sources: isotopes from ancient nuclear reactions and still-active radionuclides; molecules from space--frozen in meteorites or continuously generated in vast interstellar clouds; and the detritus of volcanic and geochemical activity. This is also the story of theorigin of life, which can be biochemically detected through the modern descendants of early microbial life-forms and from laboratory experiments in prebiotic chemistry. The author also describes the history of ideas in the study of chemistry and the development of modern theories on chemicalevolution. This is a highly readable account of central issues and ideas in modern science that will be read with absorbing interest by a wide range of students, researchers, and general readers.

    However this hypothesis is not related directly to the physics which governs the motions of atomic nuclei and electrons. It is the purpose of this important new book to show that a theory can be developed to establish the molecular structure hypothesis, demonstrating that the atoms in a molecule are real, with properties predicted and defined by the laws of quantum mechanics, and that the structure their presence imparts to a molecule is indeed a consequence of the underlying physics. As a result, the classification based upon the concept of atoms in molecules is freed from its empirical constraints and the full predictive power of quantum mechanics can be incorporated into the resulting theory--a theory of atoms in molecules. Eminently accessible and readable, the book will interest all scientists involved with experiment and observation at the atomic level, in addition to theoreticians.

    

    It has since become an important area of modern mathematical thought. This highly regarded treatise presents the classical theory of orthogonal series with rigorous attention to detail and appropriate technique, but in an easy-to-read style. The book contains a wealth of information, factual and bibliographical, that will prove especially valuable to the applied mathematician who very often does not have access to original papers. He will find here a rich compilation of general results and convenient criteria concerning Fourier series, Legendre series, Laguerre and Hermite polynomials.Until the publication of this book, much of the material had not been published in English; this excellent translation by Ainsley H. Diamond, available now for the first time in paperback, makes it widely accessible to the English-speaking mathematics community.
