As a result of significant research over the past 20 years, black holes are now linked to some of the most spectacular and exciting phenomena in the Universe, ranging in size from those that have the same mass as stars to the super-massive objects that lie at the heart of most galaxies, including our own Milky Way. This book first introduces the properties of simple isolated holes, then adds in complications like rotation, accretion, radiation, and magnetic fields, finally arriving at a basic understanding of how these immense engines work.

First Snow White encounters one of the Little People, then one of the Even Smaller People, and finally one of the Truly Infinitesimal People. And no matter how diligently she searches, the only dwarves she can find are collapsed stars Clearly, she's not at home in her well-known Brothers Grimm fairy tale, but instead in a strange new landscape that features quantum behavior, the wavelike properties of particles, and the Uncertainty Principle. She (and we) must have entered, in short, one of the worlds...

Cosmology in Scalar-Tensor Gravity covers all aspects of cosmology in scalar-tensor theories of gravity. Considerable progress has been made in this exciting area of physics and this book is the first to provide a critical overview of the research. Among the topics treated are:
-Scalar-tensor gravity and its limit to general relativity,
-Effective energy-momentum tensors and conformal frames,
-Gravitational waves in scalar-tensor cosmology,
-Specific scalar-tensor theories,
-Exact cosmological solutions and cosmological perturbations,
-Scalar-tensor...

The book is a newly arranged and revised English version of "Aufbau der Physik" by Carl Friedrich von Weizsacker. Some original chapters and sections have been deleted, and a new chapter about further insights and results of ur-theoretic research of the late 1980's and 1990's has been included. Carl Friedrich von Weizsacker combines the perspectives of science, philosophy, religion and politics with a view towards the challenges as well as the responsibilities of our time.

The process of regional-residual separation in potential field is age-old. Broadly, there are two techniques for regional-residual resolution, viz., graphical and analytical. Both the techniques have their own respective shortcomings. In this book, the authors have described the technique based on finite element method in which only eight (or twelve) nodal observed gravity values are used for the regional computation, thereby eliminating the possible contamination of anomalous fields and also the technique does not assume an explicit model and physical properties like density of rocks etc....

On May 18-21, 2004, the Max-Planck-Society s Harnack-Haus in Dahlem, Berlin hosted the international symposium "Exploring the Cosmic Frontier: Astrophysical Instruments for the 21st Century." The symposium was dedicated to exploring the complementarity and synergies between different branches of astrophysical research, by presenting and discussing the fundamental scientific problems that will be addressed in the next few decades."
