Taschenbuch. Etat : Neu. Neuware - String Theory Explained: Quantum Gravity, Extra Dimensions, Supersymmetry, and the Search for a Unified Theory of Everything is a comprehensive and accessible guide to one of the most ambitious ideas in modern physics. Designed for curious readers, science enthusiasts, and lifelong learners, this book breaks down the complex mathematics and bold concepts behind string theory into clear, engaging explanations. If you have ever wondered how physicists attempt to unify quantum mechanics and general relativity, this book provides a structured and readable path into the heart of the debate.Inside, you will explore the historical journey from Newton and Einstein to quantum field theory, uncover the deep problem of quantum gravity, and learn why physicists replaced point particles with vibrating strings. The book explains extra dimensions, Calabi Yau geometry, supersymmetry, branes, M theory, black hole thermodynamics, and the holographic principle in language that remains precise yet approachable. It also addresses the string landscape, the multiverse discussion, and the ongoing experimental challenges faced by researchers working at the frontiers of theoretical physics.Unlike highly technical textbooks, this guide emphasizes conceptual clarity and logical development. Each chapter builds on the last without repetition, giving readers a coherent understanding of how string theory evolved and why it remains central to the search for a theory of everything. You will gain insight into both the scientific framework and the philosophical implications of a universe shaped by higher dimensions and deep mathematical symmetry.Whether you are a student of physics, a fan of cosmology, or simply fascinated by big questions about reality, String Theory Explained offers a structured and thought provoking exploration of the ideas that aim to describe the fundamental structure of the cosmos.FROM THE HALF HOUR HELP SERIES OF BOOKSThe Half Hour Help Series is a collection of concise, practical guides designed to teach the basics of a subject or provide quick solutions to everyday problems.

Taschenbuch. Etat : Neu. Druck auf Anfrage Neuware - Printed after ordering - This book takes a pedagogical approach to explaining quantum gravity, supersymmetry and string theory in a coherent way. Itis 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 discussed. The Schwinger-DeWitt formalism is developed to compute the one-loop contribution to the theory and renormalizability aspects of the perturbative theory are also discussed. This follows by introducing only the very basics of a non-perturbative, background-independent, formulation of quantum gravity, referred to as 'loop quantum gravity', which gives rise to a quantization of space.In the second part the author introduces supersymmetry and its consequences. The generation of superfields is represented in detail. Supersymmetric generalizations of Maxwell's Theory as well as of Yang-Mills field theory, and of the standard model are worked out. Spontaneous symmetry breaking, improvement of the divergence problem in supersymmetric field theory, and its role in the hierarchy problem are covered. The unification of the fundamental constants in a supersymmetric version of the standard model are then studied. Geometrical aspects necessary to study supergravity are developed culminating in the derivation of its full action. The third part introduces string theory and the analysis of the spectra of the mass (squared) operator associated with the oscillating strings. The properties of the underlying fields, associated with massless particles, encountered in string theory are studied in some detail. Elements of compactification, duality and D-branes are given, as well of the generation of vertices and interactions of strings. In the final sections, the author shows how to recover GR and the Yang-Mills field Theory from string theory.…

Pictorial Cover. Etat : Fine. This is a two-volume set. Volume I covers a broad spectrum of developments in Quantum Field Theory, emphasizing those aspects that are now well consolidated and for which satisfactory theoretical descriptions have been provided. It traces the development of QFT from its inception in 1926. Volume II is an introduction to quantum gravity, supersymmetry, and string theory. The books contain footnotes, tables, figures, appendices, and an index. These HARDCOVER copies are clean and solid. Appears to be unread.…

Etat : Sehr gut. Zustand: Sehr gut | Sprache: Englisch | Produktart: Bücher | The present research explores the role of generalized uncertainty inequalities in the theory of quantum gravity. Motivated from the noncommutative nature of string theory, we show that there exists an ultraviolet/ infrared mixing dependent function. From the perspective of higher derivative stringy corrections, the uncertainty principle arises as the analyticity condition of a complex function. For a given ultraviolet cutoff, this observation non-trivially modifies the algebra of quantum observables. With the postulate that Planck length is the minimal length scale in nature, our analysis is in accordance with T-duality symmetry and the existence of both the maximum and minimum length scales. Given a finite size universe, we find that the uncertainty inequalities do exist in any quantum theory. Both the Regge behavior of string spectrum and the black hole horizon area quantization are natural consequences. The role of the generalized uncertainty principle is discussed towards the effects of quantum gravity, short distance geometries, Fourier transformation, distribution theory, discretization of spacetime and thus the perspective for the geometric origin of M-theory.…
