| Why Does E=mc2?
| | Brian Cox
| This is an engaging and accessible explanation of Einstein's equation that explores the principles of physics through everyday life. In this riveting, deeply informative exploration of Einstein's famous equation, Dr. 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. 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 observe the origin of mass in action, and record their findings.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 one of the youngest professors in the UK, and a distinguished, popular physicist, "Why Does E=MC2?" promises to be one of the most exciting and accessible explanations of the theory of relativity in recent years.
