This book gives detailed scientific advice as to the WHY and WHAT of radioactivity, and whether it can or cannot be safely used as the next world fuel. Provides an excellent shource on the Russell concepts of the nature of the universe, including a philosophic discussion of the unity of science with the Universal Creative Sourse.

    This book is especially important for information services that must be able to provide accurate information in the aftermath of a Nuclear Attack.

    A brilliantly clear and penetrating exposition of developments in physical science and mathematics brought about by the advent of non-Euclidean geometries, including in-depth coverage of the foundations of geometry, the theory of time, Einstein's theory of relativity and its consequences, other key topics.

    For advanced undergraduate or graduate physics and engineering students.

    They do not pretend to explain any observation in molecular terms but, by showing the necessary relationships between different physical properties, they reduce otherwise disconnected results to compact order, and predict new effects. This classic title, first published in 1957, is a systematic exposition of principles, with examples of applications, especially to changes of places and the conditions for stability. In all this entropy is a key concept.

    Students and professionals will find it an essential reference for calculations pertaining to hydrogen-like and helium-like atoms and their comparison with experimental results.In-depth explorations of the Dirac theory of the electron and of radiative effects include brief accounts of relevant experiments. The specific application of general field-theoretic results to atomic systems also receives a thorough examination. Author Hans A. Bethe (1906–2005), Professor of Physics at Cornell University, won the Nobel Prize in Physics in 1967. Co-author Edwin E. Salpeter is James Gilbert White Distinguished Professor of the Physical Sciences at Cornell University.

    "Scientific American," the oldest and most popular science magazine in the world, has prepared the most comprehensive and comprehensible book on the subject ever. Under the direction of renowned astronomer David H. Levy, thisspectacular book assembles the best minds in science to give clearand accessible explanations of the nature of the cosmos. Newlycommissioned essays by working scientists at the top of their fieldsand classic writings by such luminaries as Albert Einstein, FrancisCrick, and Carl Sagan take us to the frontiers of space and time-from sub-atomic particles to the edge of the universe. Both thoughtful and provocative, this book asks-and answers-the big questions, such as: o How did our solar system evolve? o What forces lie at the center of the atom? o What is the size of the universe? o What is dark matter? o What is the possibility of extraterrestrial life? o What is the importance of superstrings? o How do galaxies form?Dazzling full-color and black-and-white photographs aid in articulating the latest theories about the size, age, nature, and expansion of the universe, and make this book a delight to behold. Essays are grouped by topic, from the largest phenomena, such as the formation of the universe, down to the smallest detail, such as the makeup of an atom. In addition, each section contains an illuminating introduction by David Levy that binds the essays together and creates a whole picture. "The Scientific American Book of the Cosmos" is a valuable addition to the bookshelf of both professional astronomers and science enthusiasts alike.
