˜The œextravagant universe : exploding stars, dark energy, and the accelerating cosmos / par Kirshner, Robert P. Publication : [S.l.] : Princeton University Press, 2004 . 312 p. ; , One of the world's leading astronomers, Robert Kirshner, takes readers inside a lively research team on the quest that led them to an extraordinary cosmological discovery: the expansion of the universe is accelerating under the influence of a dark energy that makes space itself expand. In addition to sharing the story of this exciting discovery, Kirshner also brings the science up-to-date in a new epilogue. He explains how the idea of an accelerating universe--once a daring interpretation of sketchy data--is now the standard assumption in cosmology today. This measurement of dark energy--a quality of space itself that causes cosmic acceleration--points to a gaping hole in our understanding of fundamental physics. In 1917, Einstein proposed the "cosmological constant" to explain a static universe. When observations proved that the universe was expanding, he cast this early form of dark energy aside. But recent observations described first-hand in this book show that the cosmological constant--or something just like it--dominates the universe's mass and energy budget and determines its fate and shape. Warned by Einstein's blunder, and contradicted by the initial results of a competing research team, Kirshner and his colleagues were reluctant to accept their own result. But, convinced by evidence built on their hard-earned understanding of exploding stars, they announced their conclusion that the universe is accelerating in February 1998. Other lines of inquiry and parallel supernova research now support a new synthesis of a cosmos dominated by dark energy but also containing several forms of dark matter. We live in an extravagant universe with a surprising number of essential ingredients: the real universe we measure is not the simplest one we could imagine. This book invites any reader to share in the excitement of a remarkable adventure of discovery. 24 cm.

Explaining the universe : the new age of physics / par Charap,, John M. Publication : [S.l.] : Princeton University Press, 2004 . 248 p. ; , In this fascinating book, John Charap offers a panoramic view of the physicist's world as the twenty-first century opens--a view that is entirely different from the one that greeted the twentieth century. We have learned that the universe is billions of galaxies larger than we imagined--and billions of years older. We know more about how it came to be and what it is. Because of physics, we live in a world of greater danger and more convenience, smaller particles and bigger ideas. Charap introduces these ideas but spares us the math behind them. After a review of the twentieth century's thorough transformation of physics, he checks in on the latest findings from particle physics, astrophysics, chaos theory, and cosmology. His tour includes ongoing efforts to find the universe's missing matter and to account for the first moments after the big bang. Taking readers right to the field's speculative edge, he explains how superstring theory may finally unite quantum mechanics with general relativity to produce a consistent quantum theory of gravity. Along the way, Charap poses the questions that continue to inspire research. Why is the universe flat? Why can't we forecast weather better? Can Schrodinger's cat really be simultaneously dead and alive? Why does fractal geometry keep showing up in strange places? Might spacetime have eleven dimensions? What does quantum mechanics mean about the nature of our world? In this book's pages, the nonphysicist will accept as commonsensical Heisenberg's uncertainty principle, and physicists can meet across specialties. Students can access physics' critical concepts, and poets can learn a new language to describe the universe's many wonders. Taking us from the ultraviolet catastrophe that undid the Newtonian world to tomorrow's Theory of Everything, Charap brings today's most fascinating science down to Earth, where we can all enjoy it. 24 cm.

Modeling and simulation of aerospace vehicle dynamics / par Zipfel, Peter H. Publication : [S.l.] : AIAA (American Institute of Aeronautics & Ast, 2007 . 567 p. ; , This book unifies all aspects of flight dynamics for the efficient development of aerospace vehicle simulations. Now in its second edition, its purpose is still to provide the reader with a complete set of tools to build, program, and execute simulations. Unlike other books, it uses tensors for modeling flight dynamics in a form invariant under coordinate transformations. For implementation, the tensors are converted into matrices, resulting in compact computer code. The reader can pick FORTRAN templates of missiles, aircraft, or hypersonic vehicles from the complimentary "CADAC" CD-ROM to jump-start a particular application, and plot the results of CADAC Studio. It is the only textbook that combines the theory of modeling with hands-on examples of three-, five-, and six-DoF simulations. This new and enlarged edition also serves as anchor for a self-tutoring, three-part course of aerospace simulations in C++, available from AIAA. Amply illustrated with 318 figures and 44 examples, the text can be used for advanced undergraduate and graduate instruction or for self-study. Seventy eight problems and nine projects amplify the topics and develop the material further. Qualified instructors can obtain a complimentary solution manual from AIAA. This second edition contains two new appendices. The original Appendix C, which reviewed state-of-the-art FORTRAN simulations, has been replaced by the description of three self-study CD-ROMs of aerospace simulations in C++. These CDs broaden the applications of this book by spanning from simple three degrees of freedom cruise missiles to high fidelity missiles, aircraft, and hypersonic vehicles. The new Appendix D lays the theoretical foundation of tensor flight dynamics. It contains the proofs of the rotational time derivative and the Euler transformation. 24 cm.

Opportunities in high magnetic field science / par Science,, Committee on Opportunities in High Magnetic Field. Publication : [S.l.] : National Academies Press, 2005 . 188 p. ; , High-field magnets - those that operate at the limits of the mechanical and/or electromagnetic properties of their structural materials - are used as research tools in a variety of scientific disciplines. The study of high magnetic fields themselves is also important in many areas such as astrophysics. Because of their importance in scientific research and the possibility of new breakthroughs, the National Science Foundation asked the National Research Council to assess the current state of and future prospects for high-field science and technology in the United States. This report presents the results of that assessment. It focuses on scientific and technological challenges and opportunities, and not on specific program activities. The report provides findings and recommendations about important research directions, the relative strength of U.S. efforts compared to other countries, and ways in which the program can operate more effectively. 25 cm.
