The first comprehensive survey of (2+1)-dimensional quantum gravity - for graduate students and researchers.
Einstein's general theory of relativity -- currently our best theory of gravity -- is important not only to specialists, but to a much wider group of physicists. This short textbook on general relativity and gravitation offers students glimpses of the vast landscape of science connected to general relativity. It incorporates some of the latest research in the field. The book is aimed at readers with a broad range of interests in physics, from cosmology, to gravitational radiation, to high energy physics, to condensed matter theory. The pedagogical approach is "physics first": readers move very quickly to the calculation of observational predictions, and only return to the mathematical founda...
This is a short textbook on general relativity and gravitation aimed at readers with a broad range of interests in physics, from cosmology to high energy physics to condensed matter. The approach is "physics first": readers move quickly to the calculation of observational predictions and only then return to mathematical foundations.
Leading theorists share their important insights into the ongoing quest of theoretical physics to find a quantum theory of gravity.
Combining research methods from various areas of mathematics and physics, Probabilistic Models of Cosmic Backgrounds describes the isotropic random sections of certain fiber bundles and their applications to creating rigorous mathematical models of both discovered and hypothetical cosmic backgrounds. Previously scattered and hard-to-find mathematical and physical theories have been assembled from numerous textbooks, monographs, and research papers, and explained from different or even unexpected points of view. This consists of both classical and newly discovered results necessary for understanding a sophisticated problem of modelling cosmic backgrounds. The book contains a comprehensive des...
Where does consciousness fit into biology? How did life evolve? What makes us human? These are just a few of the deep and universal questions that the new science and philosophy of epigenetics may be able to answer. Epigenetics ("above and beyond genetics") is an exciting new field, but it remains relatively unknown, even as genetics has been saturating scientific news since the early 1990s. Whether it was through the Human Genome Project, the heritability of a disease, or DNA ancestry testing, most people have likely heard of genetics. But, despite its popularity, very few truly understand the scope of genetics or what in fact constitutes a gene. Genetics is often thought of as the study of...
In this book, Robert Wald provides a coherent, pedagogical introduction to the formulation of quantum field theory in curved spacetime. He begins with a treatment of the ordinary one-dimensional quantum harmonic oscillator, progresses through the construction of quantum field theory in flat spacetime to possible constructions of quantum field theory in curved spacetime, and, ultimately, to an algebraic formulation of the theory. In his presentation, Wald disentangles essential features of the theory from inessential ones (such as a particle interpretation) and clarifies relationships between various approaches to the formulation of the theory. He also provides a comprehensive, up-to-date account of the Unruh effect, the Hawking effect, and some of its ramifications. In particular, the subject of black hole thermodynamics, which remains an active area of research, is treated in depth. This book will be accessible to students and researchers who have had introductory courses in general relativity and quantum field theory, and will be of interest to scientists in general relativity and related fields.
