This is an engaging and accessible explanation of Einstein's equation that explores the principles of physics through everyday life. 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. 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.

I haven't yet gotten round to raeding the whole book but so far it is very interesting and simple to make sense of. i would reccomend this book to anyone who is interested in this sort of thing, also good delivery and packaged nicely.

 Einstein would have loved this!

Cox has the most amazing ability to break down extremely complex ideas and make them not only understandable, but fun in a way I have not encountered before. Though you dont need to have any background knowlege of mathematics or physics, it does help :)
I would highly recomend this book if you are interested in physics, the universe or just want a fun challenging read.

 Great Read

This is a brilliant read for anyone interested in physics and mind boggling stuff! Cox and Forshaw strive to make the mathematics and physics which is normally conceived as boring, more entertaining and simpler, and also adding a little history in the twist. I would highly recommend this book to anyone pursuing anything to do with physics especially the nature of the cosmos, astrophysics and particle physics!

On a personal note I want to peruse further more in the field of physics, Cox and Forshaw have helped me to further understand some unanswered questions I once had.

Play showed also its highly professional manner of delivery on time and in pristine order. Keep it up!

Not really for simpletons, but then you do not have to be a physicist.
Anyone who has seen Brian Cox on his BBC program 'Wonders of the Solar System' will know who he puts facts forward elegantly and makes them very understandable.

Don't be put off by the topic if it seems daunting. This book is a fantastic read and I hope the pair produce more.
