This book takes a pedagogical approach to explaining quantum gravity, supersymmetry and string theory in a coherent way. It is aimed at graduate students and researchers in quantum field theory and high-energy physics.

The first part of the book introduces quantum gravity, without requiring previous knowledge of general relativity (GR). The necessary geometrical aspects are derived afresh leading to explicit general Lagrangians for gravity, including that of general relativity. The quantum aspect of gravitation, as described by the graviton, is introduced and perturbative quantum GR is...

This work grapples with key issues of reality (both potentiality and actuality), scale (both local and global), context (scale and approximation, plus asymmetry/symmetry), and process (both emergence and actual events). Building on a convergence of progress in physics, emergence research, and process thought, this work highlights a new Relational Realism, which enables intuitive, yet effective, solutions to key problems in modern science.

This textbook provides a rigorous approach to tensor manifolds in several aspects relevant for Engineers and Physicists working in industry or academia. With a thorough, comprehensive, and unified presentation, this book offers insights into several topics of tensor analysis, which covers all aspects of n-dimensional spaces.

The main purpose of this book is to give a self-contained yet simple, correct and comprehensive mathematical explanation of tensor calculus for undergraduate and graduate students and for professionals. In addition to many worked problems, this book features a...

This book is on quantal density functional theory (QDFT) which is a time-dependent local effective potential theory of the electronic structure of matter. The time-independent QDFT constitutes a special case. The 2^nd edition describes the further development of the theory, and extends it to include the presence of an external magnetostatic field. The theory is based on the quantal Newtonian second and first laws for the individual electron. These laws are in terms of classical fields that pervade all space, and their quantal sources. The fields are separately representative of...

This self-contained text introduces readers to the field of high-energy atomic physics - a new regime of photon-atom interactions in which the photon energies significantly exceed the atomic or molecular binding energies, and which opened up with the recent advent of new synchrotron sources.

From a theoretical point of view, a small-parameter characteristic of the bound system emerged, making it possible to perform analytic perturbative calculations that can in turn serve as benchmarks for more powerful numerical computations. The first part of the book introduces readers to...

This volume, first published in 1921, presents a series of portraits of Einstein, thus offering glimpses in the character and private reflections of the man who changed the course of modern science. Intended neither as a biography, nor as a resume of Einsteinian physics, Einstein: The Searcher instead focusses on Einstein s relationship with the scientific project as he himself conceived it, and so is still of contemporary significance for those puzzled by the spirit of scientific enquiry.

First published in 1936, this volume contains six of the Halley Stewart Lectures originally founded "For Research towards the Christian Ideal in All Social Life" by some of the greatest of English scientists of the mid-20^th century, each a leading authority in his respective field: cosmology, physics, meteorology, medicine and genetics.

The final lecture considers the relationship between scientific knowledge and human ideals, commenting on the paradox that a century which produced such scientific advance also witnessed the most concentrated period of social, economic...

This book offers an overview of a huge range of scientific achievements in the 20^th century, specifically in the field of applied science. The majority of the essays originally appeared in papers and journals such as the Daily Worker, New Statesman and Nation, Science and Society and Nature.

Insofar as one theme runs through them, it is the application of scientific knowledge for the benefit of human society. The author is unashamed to present his perspective on some of the topics discussed in the context of his commitment to Marxism. This...

The purpose of this book is to give a systematic pedagogical exposition of the quantitative analysis of Wilson lines and gauge-invariant correlation functions in quantum chromodynamics. Using techniques from the previous volume (Wilson Lines in Quantum Field Theory, 2014), an ab initio methodology is developed and practical tools for its implementation are presented. Emphasis is put on the implications of gauge invariance and path-dependence properties of transverse-momentum dependent parton density functions. The latter are associated with the QCD factorization approach to semi-inclusive...
