Electromagnetism is one of the four fundamental forces in nature, and underlies almost everything we experience in our daily lives, whether we realise it or not. The complete theory was first written down in the late 19th century, and remains an essential part of a scientific education. The mathematics behind the theory, however, can be intimidatingly complex. Furthermore, it is not always clear to beginners why the theory is either useful or interesting, nor how it relates to modern research in theoretical physics.The aim of this book is to guide students towards a detailed understanding of the full theory of electromagnetism, including its practical applications. Later chapters introduce more modern formulations of the theory than are found in traditional undergraduate courses, thus bridging the gap between a first course in electromagnetism, and the advanced concepts needed for further study in physics. The final chapter reviews exciting current research stating that possible theories of (quantum) gravity may be much more closely related to electromagnetism than previously thought.Throughout the book, an informal conversational style is used to demystify intimidating concepts. Relevant mathematical ideas are introduced in a self-contained manner, and exercises are provided with full solutions to aid understanding. This book is essential reading for anyone undertaking a physics degree, but will also be of interest to engineers and chemists.

What is our universe made of? How did it get here, and how will it end? Why are many scientists currently so excited about these questions? And why is everybody else so scared of the one subject – physics – that promises to give us all the answers?This book is here to help. Its main aim is to explain a remarkable new idea that has arisen in recent years, that tells us all of our current theories of nature are much more closely related than previously thought possible. It will tell you where these theories come from, why understanding them has traditionally been so difficult, and about the tantalising new hints that our understanding of nature is about to significantly change.More than this, the book will explain quite why it is so important that more people join the greatest pursuit of knowledge that our species has ever seen. Practical advice is given on how to become a scientist, so that people from all backgrounds may be inspired to become the leading thinkers of the future.
