General relativity is one of the most profound statements in science. It is a theory of gravity that allows us to model the large-scale structure of the Universe, to understand and explain the motions and workings of stars, to reveal how gravity interacts with light waves and even how it hosts its own gravitational waves. It is central to our notions of where the Universe comes from and what its eventual fate might be. For those wishing to learn physics, general relativity enjoys a dubious distinction. It is frequently viewed as a difficult theory, whose mastery is a rite of passage into the world of advanced physics and is described in an array of unforgiving, weighty textbooks aimed firmly at aspiring professionals. Written by experimental physicists and aimed at providing the interested amateur with a bridge from undergraduate physics to general relativity, this book is designed to be different. The imagined reader is a gifted amateur possessing a curious and adaptable mind looking to be told an entertaining and intellectually stimulating story, but who will not feel patronised if a few mathematical niceties are spelled out in detail. Using numerous worked examples, diagrams and careful physically motivated explanations, this book will smooth the path towards understanding the radically different and revolutionary view of the physical world that general relativity provides and which all physicists should have the opportunity to experience.

An understanding of the quantum mechanical nature of magnetism has led to the development of new magnetic materials which are used as permanent magnets, sensors, and information storage. Behind these practical applications lie a range of fundamental ideas, including symmetry breaking, order parameters, excitations, frustration, and reduced dimensionality.This superb new textbook presents a logical account of these ideas, staring from basic concepts in electromagnetsim and quantum mechanics. It outlines the origin of magnetic moments in atoms and how these moments can be affected by their local environment inside a crystal. The different types of interactions which can be present between magnetic moments are described. The final chapters of the book are devoted to the magnetic properties of metals, and to the complex behaviour which can occur when competing magnetic interactions are present and/or the system has a reduced dimensionality. Throughout the text, the theorectical principles are applied to real systems. There is substantial discussion of experimental techniques and current reserach topics. The book is copiously illustrated and contains detailed appendices which cover the fundamental principles.
