D. Allan Bromley – författare

D. Allan Bromley, one of the world's leading nuclear physicists, was The Assistant to President George Bush for Science and Technology Policy from August 1989 to January 1993. He was the first Science Advisor to have this Cabinet-level rank.In this engrossing memoir of his years at the White House, Bromley brings the unique perspective of a scientist to the political realities of policy making with the President and his other Senior Assistants. Bromley recalls his efforts to rebuild the Office of Science and Technology Policy and the Federal Coordinating Council for Science, Engineering, and Technology, organizations that develop science policy and that oversee the federal agencies responsible for the science and technology enterprise of the United States; the Bush Administration initiatives to improve the global environment, the health and quality of life of all Americans, national security, international science and technology, and funding of U.S. science and technology; and the landmark reports prepared under his supervision that called for a revamping of the science and mathematics curricula in U.S. precollege education and a rethinking of the relationships between the research intensive universities and the federal government. He discusses the people with whom he interacted—George Bush, John Sununu (Bromley's strongest ally in the White House), Richard Darman, Senator Al Gore, and many others—and he includes provocative anecdotes about his attempts—many successful—to foster closer cooperative scientific ventures with other countries. Bromley's memoir is both a broad overview of the role of science and technology in the Bush Administration and an insider's account of the ambiance, personalities, and politics that mold specific policy decisions in Washington. It is fascinating and thought-provoking reading.

Facets of Physics contains the major papers in the symposium on May 3, 1968 dedicated to Gregory Breit''s honor. This book covers different facets of physics and the contributions made by Breit. The book reviews the development of the current knowledge of the nucleon-nucleon interaction, the status of understanding on the nuclear matter, and the detailed treatment of the finite nuclei. It also examines the consequences of the short-range nature of nuclear forces, the importance of the Breit interaction in atomic physics and quantum thermodynamics, and different proton-proton scattering studies. This book is a good reading material for nuclear physicists and other scientists who are interested in atomic physics and quantum thermodynamics.

In this amazing tour d'horizon, D. Allan Bromley uses the occasion of the centenary of the American Physical Society to reflect upon the growth of physics over the past 100 years, its fragmentation into numerous subdisciplines, the impact physics has had upon modern technology, and the re-emergence of the fundamental unity of the discipline in recent years. Hundreds of historical illustrations accompany the text. Bromley conveys much of the excitement and wonder that research in physics generated in the 20th century and asks what new things are in store in the next century. He covers such topics as relativity and quantum mechanics, the Manhattan project, superconductivity, transistors and the revolution brought about by solid-state electronics, protein folding, the uses of nuclear and atomic physics in biology and medicine, plate tectonics, the expansion of the universe and the Big Bang, and gravitational radiation. Bromley, the Sterling Professor of the Sciences and Dean of Yale University, served as Assistant to the President for Science and Technology Policy 1989-1993 and was president of the American Physical Society in 1997.One of the World's leading nuclear scientists, he was founder and director of Yale's nuclear structure laboratory and has received numerous medals and awards, including the National Medal of Science.

For 75 years the stopping of energetic ions in matter has been a subject of great theoretical and experimental interest. The theoretical treatment of the stopping of ions in matter is largely due to the work of Bohr, 1-3 Bethe,4-6 Bloch,7. s and Lindhard,9-12 and it has been reviewed by Bohr,3 Fano,13 17 20 Jackson,14 Sigmund,15 Ahlen,16 and Ziegler et al. - Soon after the discovery of energetic particle emission from radioactive materials, there was interest in how these corpuscles were slowed down in traversing matter. In 1900, Marie Curie stated 21 the hypothesis that Hies rayons alpha sont des projectiles materiels susceptibles de perdre de leur vitesse en travers ant la matiere. " Early attempts to evaluate this were incon- clusive for there was not yet an accurate proposed model of the atom. Enough experimental evidence was collected in the next decade to make stopping power theory one of the central concerns of those attempting to develop an atomic model. J. J. Thomson, director of the prestigious Cavendish Laboratory, and Niels Bohr, a fresh postdoctoral scientist at Rutherford's Manchester Laboratory, both published almost simultaneously22.23 an analysis of the stopping of charged particles by matter, and each contained many of their divergent ideas on the model of an atom. Thomson ignored in his paper the Rutherford alpha-particle scattering 24 experiment of a year before. But the nuclear atom with a heavy positively 25 charged core was the basis of Bohr's ideas.

Stories About Sets discusses the cardinality of sets and mathematical concepts, such as function, curve, surface, dimensions, and the paradoxical properties of curves and surfaces. The book reviews sets, operations on sets, the empty set, subsets, the universal sets, intersection of sets, union of sets, partitioning of sets, and boolean algebras. The text also discusses the cardinality of sets, including equality between sets, countable sets, unequal sets, the uncountability of the continuum, the existence of transcendental numbers, and the enigmatic axiom. The book analyzes if a part can be equal to the whole (which turns out to be true if it is applied to infinite sets). The text also discusses the arithmetic of the infinite such as involving the multiplication of infinite cardinalities. The book explains some remarkable functions and curves, the Dirichlet''s function, Cantor''s set, points of fracture, and continuous functions whose graphs possess a tangent at no point. The text shows how to construct a closed curve of infinite length or a curve passing through all the points of a square. The book can prove interesting and highly educational for students with mathematic or algebra subjects, as well as for academicians involved in teaching statistics or mathematics.

Crystals: Their Role in Nature and in Science provides the description of the phenomena and concepts and essential facts and ideas in the study of crystals. The book is divided into two parts. Part 1 discusses the growth and various forms of crystals. Under this section, topics on the etymology of the word "crystal", the existence of crystals, how crystals grow, stacking patterns, and various crystal symmetries are presented. Part 2 covers the crystal structure and how it interacts with light and X-rays. This part discusses some strange light effects that some crystals make; the production of beautiful and scientifically significant color patterns; the possible types of space patterns in crystals; and the use of X-ray in finding the details of the internal atomic pattern of crystals. Crystallographers and laymen interested in the study and appreciation of crystals will find the book invaluable.

Finite Permutation Groups provides an introduction to the basic facts of both the theory of abstract finite groups and the theory of permutation groups. This book deals with older theorems on multiply transitive groups as well as on simply transitive groups. Organized into five chapters, this book begins with an overview of the fundamental concepts of notation and Frobenius group. This text then discusses the modifications of multiple transitivity and can be used to deduce an improved form of the classical theorem. Other chapters consider the concept of simply transitive permutation groups. This book discusses as well permutation groups in the framework of representation theory. The final chapter deals with Frobenius'' theory of group characters. This book is a valuable resource for engineers, mathematicians, and research workers. Graduate students and readers who are interested in finite permutation groups will also find this book useful.

Noneuclidean Geometry focuses on the principles, methodologies, approaches, and importance of noneuclidean geometry in the study of mathematics. The book first offers information on proofs and definitions and Hilbert''s system of axioms, including axioms of connection, order, congruence, and continuity and the axiom of parallels. The publication also ponders on lemmas, as well as pencil of circles, inversion, and cross ratio. The text examines the elementary theorems of hyperbolic geometry, particularly noting the value of hyperbolic geometry in noneuclidian geometry, use of the Poincaré model, and numerical principles in proving hyperparallels. The publication also tackles the issue of construction in the Poincaré model, verifying the relations of sides and angles of a plane through trigonometry, and the principles involved in elliptic geometry. The publication is a valuable source of data for mathematicians interested in the principles and applications of noneuclidean geometry.

Geometric Transformations, Volume 1: Euclidean and Affine Transformations focuses on the study of coordinates, trigonometry, transformations, and linear equations. The publication first takes a look at orthogonal transformations, including orthogonal transformations of the first and second kinds; representations of orthogonal transformations as the products of fundamental orthogonal transformations; and representation of an orthogonal transformation of space as a product of fundamental orthogonal transformations. The text then examines similarity and affine transformations. Topics include properties of affine mappings, Darboux''s lemma and its consequences, affine transformations in coordinates, homothetic transformations, similarity transformations of the plane in coordinates, and similarity mapping. The book takes a look at the representation of a similarity transformation as the product of a homothetic transformation and an orthogonal transformation; application of affine transformations to the investigation of properties of the ellipse; and representation of any affine transformation as a product of affine transformations of the simplest types. The manuscript is a valuable reference for high school teachers and readers interested in the Euclidean and affine transformations.

Geometric Transformations, Volume 2: Projective Transformations focuses on collinearity-preserving transformations of the projective plane. The book first offers information on projective transformations, as well as the concept of a projective plane, definition of a projective mapping, fundamental theorems on projective transformations, cross ratio, and harmonic sets. Examples of projective transformations, projective transformations in coordinates, quadratic curves in the projective plane, and projective transformations of space are also discussed. The text then examines inversion, including the power of a point with respect to a circle, definition and properties of inversion, and circle transformations and the fundamental theorem. The manuscript elaborates on the principle of duality. The manuscript is designed for use in geometry seminars in universities and teacher-training colleges. The text can also be used as supplementary reading by high school teachers who want to extend their range of knowledge on projective transformations.
