This book is a broad-based text intended to help the growing student body interested in constructing and applying methods of effective field theory to solve problems in their research. It begins with a review of using symmetries to identify the relevant degrees of freedom in a problem, and then presents a variety of methods that can be used to construct various effective theories. A detailed discussion of canonical applications of effective field theory techniques with increasing complexity is given, including Fermi's weak interaction, heavy-quark effective theory, and soft-collinear effective theory. Applications of these techniques to study physics beyond the standard model, dark matter, and quantum and classical gravity are explored. Although most examples come from questions in high-energy physics, many of the methods can also be applied in condensed-matter settings. Appendices include various factoids from group theory and other topics that are used throughout the text, in an attempt to make the book self-contained.

This nontechnical introduction to the theory of gravitation deals with those parts of the theory that are essential to the beginning student of general relativity, giving all the mathematics necessary for understanding the theory. In this revised second edition, the experimental evidence has been updated and the sections on quantum physics have been rewritten and enlarged. Starting with the foundations of Riemannian geometry and the tensor calculus, the author formulates and works out the essential laws of physics in Riemannian space. Next, the Einstein field equations are derived. All important applications of the theory are dealt with, including issues of current importance, in particular the Schwarzschild metric, gravitational waves, gravitational collapse, black holes and cosmological models. All the associated basic physical problems are fully discussed, but many results that draw heavily on mathematics are given without derivation. The relation to observations and the latest numerical results obtained from them is established.

The universe that science reveals to us can seem far outside the comfort zone of the human mind. Subjects near and far open up dizzying vistas, from the infinitesimal to the colossal. Humanity, the unlikely product of uncountable coincidences on unimaginable scales, inhabits a tumultuous universe that extends from our immediate environs to the most distant galaxies and beyond. But when the mind balks at the vertiginous complexity of the universe, science unveils the elegance amid the chaos.In this book, Thomas R. Scott ventures into the known and the unknown to explain our universe and the laws that govern it. The Universe as It Really Is begins with physics and the building blocks of the universe-time, gravity, light, and elementary particles-and chemistry's ability to explain the interactions among them. Scott, with the assistance of James Lawrence Powell, next tours the earth and atmospheric sciences to explain the forces that shape our planet and then takes off for the stars to describe our place in the cosmos. He provides vivid introductions to our collective scientific inheritance, narrating discoveries such as the shape of the atom and the nature of the nucleus or how we use GPS to measure time and what that has to do with relativity. A clear demonstration of the power of scientific reasoning to bring the incomprehensible within our grasp, The Universe as It Really Is gives an engrossing account of just how much we do understand about the world around us.

Thoroughly revised and updated, this textbook provides a pedagogical introduction to relativity. It is self-contained, but the reader is expected to have a basic knowledge of theoretical mechanics and electrodynamics. It covers the most important features of both special and general relativity, as well as touching on more difficult topics, such as the field of charged pole-dipole particles, the Petrov classification, groups of motions, gravitational lenses, exact solutions and the structure of infinity. The necessary mathematical tools (tensor calculus, Riemannian geometry) are provided, most of the derivations are given in full, and exercises are included where appropriate. Written as a textbook for undergraduate and introductory graduate courses, it will also be of use to researchers working in the field. The bibliography gives the original papers and directs the reader to useful monographs and review papers.

This book presents Einstein's theory of space and time in detail, and describes the large-scale structure of space, time and velocity as a new cosmological special relativity. A cosmological Lorentz-like transformation, which relates events at different cosmic times, is derived and applied. A new law of addition of cosmic times is obtained, and the inflation of the space at the early universe is derived, both from the cosmological transformation. The relationship between cosmic velocity, acceleration and distances is given. In the appendices gravitation is added in the form of a cosmological g
