The most accessible, entertaining, and enlightening explanation of the best-known physics equation in the world, as rendered by two of today's leading scientists.

Professor Brian Cox and Professor Jeff Forshaw go on a journey to the frontier of 21st century science to consider the real meaning behind the iconic sequence of symbols that make up Einstein's most famous equation, E=mc2. Breaking down the symbols themselves, they pose a series of questions: What is energy? What is mass? What has the speed of light got to do with energy and mass? In answering these questions, they take us to the site of one of the largest scientific experiments ever conducted. Lying beneath the city of Geneva, straddling the Franco-Swiss boarder, is a 27 km particle accelerator, known as the Large Hadron Collider. Using this gigantic machine--which can recreate conditions in the early Universe fractions of a second after the Big Bang--Cox and Forshaw will describe the current theory behind the origin of mass.

Alongside questions of energy and mass, they will consider the third, and perhaps, most intriguing element of the equation: 'c' - or the speed of light. Why is it that the speed of light is the exchange rate? Answering this question is at the heart of the investigation as the authors demonstrate how, in order to truly understand why E=mc2, we first must understand why we must move forward in time and not backwards and how objects in our 3-dimensional world actually move in 4-dimensional space-time. In other words, how the very fabric of our world is constructed. A collaboration between two of the youngest professors in the UK, Why Does E=mc2? promises to be one of the most exciting and accessible explanations of the theory of relativity in recent years.

The authors of this book were able to make sophisticated concepts easy to understand for the reader through great analogies, step-by-step processes, and examples. If you're interested in the subject of the title of this book and don't have a strong physics background, this book will do the trick. If you have a strong physics background, you might find parts of the book slow and skip pages. Happy Reading! I found this book very interesting.

This is much better than Hawkin's A Brief History of Time. Hawkin's gives only tantalizing but unsatisfactory explanations of Physical Theories. If you have a reasonable grasp of high school math and are able to think things through, Fox and Forshaw lead you through some real revelations. Of course, these requirements probably exclude a lot of people in our mathematically incompetent society. There is only one weak chapter in the book and the failure to elucidate the last step of their explanation of Einstein's famous formula (a rabbit out of a hat actually). Otherwise, it's the best book on the wondrous world of great physical theories.

A wonderful well explaned book up to page 77 where they introduce a formula out of the blue without explaining why they changed the "+" sign to a "-" sign. I couldn't figure out what they were doing and completely liost the thread.

This book provides a very in-depth view of relativity with just the most influential formula.

I like this book because there are some new analogies that are easy to remember.

However, I have to say that this book is still a bit too lengthy and lacks a concise summary in the end of every chapter.
