Grand Unified Theories introduces the application of gauge field theories to a unified description of the strong, electromagnetic, weak, and gravitational interactions. The phenomenological aspects of the work are emphasized and explicit calculations presented. Many of the aspects of current research, including technicolor models, supersymmetry and supergravity, and the cosmological implications of these theories, are discussed in this book.This book is suitable for graduate students with a background in quantum mechanics, and experimental and theoretical particle physicists who want to understand the grand unified theories.

These course-tested lectures provide a technical introduction to Supersymmetric Grand Unified Theories (SUSY GUTs), as well as a personal view on the topic by one of the pioneers in the field. While the Standard Model of Particle Physics is incredibly successful in describing the known universe it is, nevertheless, an incomplete theory with many free parameters and open issues. An elegant solution to all of these quandaries is the proposed theory of SUSY GUTs. In a GUT, quarks and leptons are related in a simple way by the unifying symmetry and their electric charges are quantized, further the relative strength of the strong, weak and electromagnetic forces are predicted. SUSY GUTs additionally provide a framework for understanding particle masses and offer candidates for dark matter. Finally, with the extension of SUSY GUTs to string theory, a quantum-mechanically consistent unification of the four known forces (including gravity) is obtained. The book is organized in three sections: the first section contains a brief introduction to the Standard Model, supersymmetry and the Minimal Supersymmetric Standard Model. Then SUSY GUTs in four space-time dimensions are introduced and reviewed. In addition, the cosmological issues concerning SUSY GUTs are discussed. Then the requirements for embedding a 4D SUSY GUT into higher-dimensional theories including gravity (i.e. String Theory) are investigated. Accordingly, section two of the course is devoted to discussing the so-called Orbifold GUTs and how in turn they solve some of the technical problems of 4D SUSY GUTs. Orbifold GUTs introduce a new set of open issues, which are then resolved in the third section in which it is shown how to embed Orbifold GUTs into the E(8) x E(8) Heterotic String in 10 space-time dimensions.

General theorem providing a mathematical basis for a Grand Unified Field Theory or a Theory of Everything (TOE) is presented. The Grand Unified Theorem produces a set of unified field equations from which Yang-Mills equations, other physical equations, and in general, mathematical equations, which have ever been known to human beings, can be recovered. The solution seems to mathematically represent the modification of space-time structure predicted by Einstein's general relativity theory. A good part of the material presented in this work has been reviewed by the American Mathematical Society and the European Mathematical Society in the Zentralblatt fur Mathematik.

General theorem providing a mathematical basis for a grand Unified Field Theory (GUT) is presented. The proof of the theorem is shown to be a recent work entitled 'Generalised Mathematical Proof of Einstein's Theory Using a New Group Theory', which has been reviewed by the American Mathematical Society. This work provides generic solutions to the unified field, from which both the Newtonian and Einsteinian gravitational fields seem to be recoverable. Furthermore, the electromagnetic field seems to be recoverable also from these solutions. Since the investigation does not assume the existence of particles a priori, matter could therefore be interpreted as high field intensity. Therefore, nuclear force fields (strong and weak) seem to be included. The solution seems to mathematically represent the modification of space-time predicted by Einstein's general relativity theory.

From Simon & Schuster, Superforce is Paul Davies' latest work that searches for a grand unified theory of nature. Superforce explains how recent discoveries in physics and the new cosmology have transformed concepts of the physical world by linking space, time, matter, force, creation, order, and mind into the ultimate scientific theory.

From personal loss to phantom diseases, The Empathy Exams is a bold and brilliant collection, winner of the Graywolf Press Nonfiction Prize A Publishers Weekly Top Ten Essay Collection of Spring 2014 Beginning with her experience as a medical actor who was paid to act out symptoms for medical students to diagnose, Leslie Jamison's visceral and revealing essays ask essential questions about our basic understanding of others: How should we care about each other? How can we feel another's pain, especially when pain can be assumed, distorted, or performed? Is empathy a tool by which to test or even grade each other? By confronting pain—real and imagined, her own and others'—Jamison uncovers a personal and cultural urgency to feel. She draws from her own experiences of illness and bodily injury to engage in an exploration that extends far beyond her life, spanning wide-ranging territory—from poverty tourism to phantom diseases, street violence to reality television, illness to incarceration—in its search for a kind of sight shaped by humility and grace.

The theoretical understanding of elementary particle interactions has under gone a revolutionary change during the past one and a half decades. The spontaneously broken gauge theories, which in the 1970s emerged as a prime candidate for the description of electro-weak (as weIl as strong) interactions, have been confirmed by the discovery of neutral weak currents as weIl as the w- and Z-bosons. We now have a field theory of electro-weak interactions at energy scales below 100 GeV-the Glashow-Weinberg-Salam theory. It is a renormalizable theory which enables us to do calculations without en countering unnecessary divergences. The burning question now is: Wh at lies ahead at the next level of unification? As we head into the era of supercolliders and ultrahigh energy machines to answer this question, many ap, pealing possi bilities exist: left-right symmetry, technicolor, compositeness, grand unifica ti on, supersymmetry, supergravity, Kaluza-Klein models, and most recently superstrings that even unify gravity along with other interactions. Experi ments will decide if any one or any combination of these is to be relevant in the description of physics at the higher energies. As an outcome of our con fidence in the possible scenerios for elementary particle physics, we have seen our understanding of the early uni verse improve significantly.
