About this ebook

The international bestseller: an introduction to the theory of relativity by the eminent physicists Brian Cox and Jeff Forshaw

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 light-while exploding commonly held misconceptions-they 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.

Ratings and reviews

Spends more time apologizing for the upcoming math then simply explaining the math. Randomly introduces equations with no explainations why or what anything means, instantly changed to other forms because just trust me. It's a book to explain something show the work one step at a time. Useless read if you actually want to learn anything.

I will have to re-read this book a few more times before I fully understand some of the concepts. It was an interesting read and definitely opened my mind. The writing style is slightly disjointed and can be annoying waiting for the authors to get back to the main subject, but overall a good read, which at times I couldn't put down.

It at least gives me an idea of what I have to expect along with everyone else who is interested in giving this a read do that we are not going, wait a minute, that all messed up, whti am I looking at here and oh I'm not nuts it's wrong
