It is always hard to know where to make your pitch. This must be true of every non-fiction title, but I expect it is particularly true of physics. One can't get any more iconic than the formula at the heart of this title, but very few of us know what it really means or why it is so important. I got interested in finding out about the time reports were leaking out of CERN about a particle that was faster than light. I thought it was time to turn to Cox and Forshaw for help (again). Of course they supplied the answers, but pitched at a level that was a bit too general for my liking. I was having fun with the maths (now that I don't need to pass exams) and getting into the dimensions they explore in the text when, suddenly I couldn't follow the math myself and I read the dreaded words (or words to the effect of), "take it from me, if you do the maths, this is the result". I wanted to do the maths. So, i ordered the hardcopy from Amazon, hoping it would be filled with lots of nice tables, diagrams and appendices. There are some diagrams, but the detail is omitted. That's fine of course for where the authors pitched the text, but I was a bit disappointed. I of course went out and got Physics for Dummies (or something akin to it), then went onto a text book and now I'm happy and ready to write this review.
The rub is, if you know nothing and are happy with something, then you'll be well pleased with this. If you want to do the math (like me) then it's a beginning, not an ending.
Jeff Forshaw reads the title with interest and is easy to listen to. No problem with the performace, at all.

Audio books, in the main, are an effective means of absorbing difficult concepts.
There are however pit-falls. E=MC2 falls into one of them.
This audio version only needs a few diagrams to make it the best tutorial on Relativity.
A complementary web site would lift it from frustratingly incomplete to brilliant.

There is no denying that relativity is not a subject that most of us need to understand. I'm not sure if it's something that most of can even begin to understand whether we need to or not. That said 'Why Does E=MC2 and Why Should We Care' goes some way to making sense of the subject for the layman using real life examples and simple mathematical explanations. Read by one of the authors, Professor Jeff Forshaw, the narration is authoritative without patronising the listener. I didn't think I would enjoy this as much as I did but it was a really good listen and I am happy to give it 5 stars.

For the first time I actually understand about time and the observer.
Brilliant book enhanced by the readers accent.
The descriptions work and while the spoken equations get a little confusing - switched off for bits - the overall value of the book is excellent.
Knocks spots of books like "A brief history of time" for ease of understanding.

I love when an author is willing, clear and interesting enough to read his own work. This is one of those times. Although some of the formulas explained would be a lot easier to digest visually, they're not necessary to get a reasonable grasp of most of the concepts explained.
I will have to listen again to be sure I pick up the parts I missed, but overall I learned so much on the first pass. I enjoyed the occasional subtle humour too.
