Why Does E=mc2? (And Why Should We Care?)

What does E=mc2 actually mean? Dr. Brian Cox and Professor Jeff Forshaw go on a journey to the frontier of twenty-first century science to unpack Einstein's famous equation. Explaining and simplifying notions of energy, mass, and lightwhile exploding commonly held misconceptionsthey demonstrate how the structure of nature itself is contained within this equation. Along the way, we visit the site of one of the largest scientific experiments ever conducted: the now-famous Large Hadron Collider, a gigantic particle accelerator capable of re-creating conditions that existed fractions of a second after the Big Bang.A collaboration between one of the youngest professors in the United Kingdom and a distinguished popular physicist,Why Does E=mc2?is one of the most exciting and accessible explanations of the theory of relativity.

Brian Cox is a distinguished particle physicist and popular TV host who divides his time between Manchester, England, and Geneva, Switzerland.

Jeff Forshaw is a professor at the University of Manchester and a recipient of the Institute of Physics Maxwell Medal. He lives in Manchester, England.
