This volume is dedicated to Jirí Bičák on the occasion of his 60th birthday. The authors are his former students who currently work in the fields of general relativity, astrophysics, theoretical physics and cosmology. Unlike in traditional Festschrifts with many short contributions, they present several comprehensive surveys and elaborate original works. The subjects range from the motion of stars in galactic nuclei to quantum mechanics on a boundary, and include current topics such as cosmological perturbations, effects of a repulsive cosmological constant, discs around black holes and gravitational waves. An unconventional introductory essay revives Prague's inspirations as personified by Tycho Brahe, Johannes Kepler, Christian Doppler, Ernst Mach, Albert Einstein and others.
"Though Einstein is undoubtedly one of the most important figures in the history of modern science, he was in many respects marginal. Despite being one of the creators of quantum theory, he remained skeptical of it, and his major research program while in Princeton--the quest for a unified field--ultimately failed. In this book, Michael Gordin explores this paradox in Einstein's life by concentrating on a brief and often overlooked interlude: his tenure as professor of physics in Prague, from April of 1911 to the summer of 1912. Though often dismissed by biographers and scholars, it was a crucial year for Einstein both personally and scientifically: his marriage deteriorated, he began thinking seriously about his Jewish identity for the first time, he attempted a new explanation for gravitation-which though it failed had a significant impact on his later work-and he met numerous individuals, including Max Brod, Hugo Bergmann, Philipp Frank, and Arnošt Kolman, who would continue to influence him. In a kind of double-biography of the figure and the city, this book links Prague and Einstein together. Like the man, the city exhibits the same paradox of being both central and marginal to the main contours of European history. It was to become the capital of the Czech Republic but it was always, compared to Vienna and Budapest, less central in the Habsburg Empire. Moreover, it was home to a lively Germanophone intellectual and artistic scene, thought the vast majority of its population spoke only Czech. By emphasizing the marginality and the centrality of both Einstein and Prague, Gordin sheds new light both on Einstein's life and career and on the intellectual and scientific life of the city in the early twentieth century"--
The Marcel Grossmann Meetings are three-yearly forums that meet to discuss recent advances in gravitation, general relativity and relativistic field theories, emphasizing their mathematical foundations, physical predictions and experimental tests. These meetings aim to facilitate the exchange of ideas among scientists, to deepen our understanding of space-time structures, and to review the status of ongoing experiments and observations testing Einstein's theory of gravitation either from ground or space-based experiments. Since the first meeting in 1975 in Trieste, Italy, which was established by Remo Ruffini and Abdus Salam, the range of topics presented at these meetings has gradually widened to accommodate issues of major scientific interest, and attendance has grown to attract more than 900 participants from over 80 countries.This proceedings volume of the eleventh meeting in the series, held in Berlin in 2006, highlights and records the developments and applications of Einstein's theory in diverse areas ranging from fundamental field theories to particle physics, astrophysics and cosmology, made possible by unprecedented technological developments in experimental and observational techniques from space, ground and underground observatories. It provides a broad sampling of the current work in the field, especially relativistic astrophysics, including many reviews by leading figures in the research community.
The aim of this monograph is to outline the symbolism, practical use and contextual meaning of the terms, metaphors and names from the field of natural sciences in the art of Otokar Březina. The present volume of nine studies written between 2003 and 2013 (O. Březina’s Galium, Ear of Grain in the Work of Otokar Březina, Vitis vinifera L. ssp. sativa /DC./ Hegi in the Works of Otokar Březina, Trees in the Poetic Works of Otokar Březina, Flora in the Work of Otokar Březina, Flowers in the Work of Otokar Březina, Otokar Březina’s “Geographical” Geology?, Březina’s Stones and Gemstones, Březina’s Stones and Gemstones II) is devoted to selected problems concerning the images, metaphors and generally the use of terminology from natural sciences in the poems, essays and correspondence of the prominent poet of Czech and European symbolism, Otokar Březina (1868–1929). The surprisingly frequently and skilfully used terminology from the sphere of natural sciences is an irreplaceable component part of the poet’s work and is perceived as its integral part both by the readers’ and specialists’ public. The aim of the book Nature in Otokar Březina’s Work is to mediate Březina’s work to foreign readers and at the same time to propagate the constantly good name of Czech literature beyond the geopolitical, geographical and language sphere of exclusively Czech milieu

The masses of neutron stars are limited by an instability to gravitational collapse and an instability driven by gravitational waves limits their spin. Their oscillations are relevant to x-ray observations of accreting binaries and to gravitational wave observations of neutron stars formed during the coalescence of double neutron-star systems. This volume includes more than forty years of research to provide graduate students and researchers in astrophysics, gravitational physics and astronomy with the first self-contained treatment of the structure, stability and oscillations of rotating neutron stars. This monograph treats the equations of stellar equilibrium; key approximations, including slow rotation and perturbations of spherical and rotating stars; stability theory and its applications, from convective stability to the r-mode instability; and numerical methods for computing equilibrium configurations and the nonlinear evolution of their oscillations. The presentation of fundamental equations, results and applications is accessible to readers who do not need the detailed derivations.
This Is A New Release Of The Original 1653 Edition.
Einstein's theory of general relativity is a theory of gravity and, as in the earlier Newtonian theory, much can be learnt about the character of gravitation and its effects by investigating particular idealised examples. This book describes the basic solutions of Einstein's equations with a particular emphasis on what they mean, both geometrically and physically. Concepts such as big bang and big crunch-types of singularities, different kinds of horizons and gravitational waves, are described in the context of the particular space-times in which they naturally arise. These notions are initially introduced using the most simple and symmetric cases. Various important coordinate forms of each solution are presented, thus enabling the global structure of the corresponding space-time and its other properties to be analysed. The book is an invaluable resource both for graduate students and academic researchers working in gravitational physics.

His research interests include quantum gravity, classical gravity, and semi-classical gravity.
Here, quantum and cosmological effects, which arise from both gravity theories in four and higher dimensions and from metric-affine theories, are investigated. Part Three is devoted to cosmological and inflationary scenarios. Local effects, such as the influence of scalar fields in protogalactic interactions, numerical studies of the collapse of molecular cores, as well as the inverse inflationary problem and the blue eigenvalue spectrum of it, are considered. Moreover, the role of scalar fields as dark matter and quantum cosmology in the Bergman-Wagoner and Gowdy theories, together with the relation of the conformal symmetry and deflationary gas universe, are likewise presented. The last part of the book includes some mixed topics which are still in the experimental stage.
