A terrific explanation of E=MC2

This book gives a deep and complete explanation of Einstein's brilliant insight and equation in language that is fairly easy to follow and with a minimum of maths.

That said I've still listened to it 3 times to keep some of the concepts clear in my mind and I'm sure I'll be listening again. That's because space time is a difficult thing for us to grasp. However this book does an excellent job of giving clever thought experiments and understandable explanations of the various aspects of the theory.

There are also many insights I'd never been aware of before like why the speed of light is a universal speed limit.

The maths involved is not overly complex though I found it helpful to write down the maths involved so I could follow it more easily.

There are many aspects to understanding the subject and the book devotes a chapter to each. This provides a clear framework from which to glean a deeper insight into Einstein's work.

Overall I have not come across a better or more complete explanation of this famous and important equation. Even if you are familiar with the concepts (like I thought I was) I feel it describes and connects the various concepts in a clever, insightful and satisfying way that has given me a more complete understanding.

I now feel I could explain E=MC2 to an interested party with confidence!

No PDF !!

Great book, but without a PDF to refer to for the important formulas, derivations and diagrammatic concepts it made the Audible version very unsatisfactory.

Expand your mind

Don't be frightened by the thought of complex mathematical equations, this book glides over those and unlocks the real beauty behind Einsteins theory.
The final chapter is especially rewarding as it pulls all the other information together.

Excellent way of explaining

Very well explained.
Have been trying to get my head around relativity for years -
and this gave me a solid understanding of the core logic
and its implications.
The narrator was a co-author so it doesn't sound like he is
'reading', just explaining naturally.

fabulous

beautifully narrated. easy to follow. I will read it again more slowly with more focused thought but great overview, have already learnt lots and a subsequent read will unlock more understanding, I am sure.

Special & General Relativity reasonably accessible

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.

Great explanation

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.

Difficult to follow in audiobook form

Enjoyable and eye opening but there are many points in the book where I wanted to have the equations on paper in front of me.

Yes we should care....

...this is not entirely esoteric, this is fundamental knowledge that gives an alternative perspective to our lives. It's actually quite therapeutic to doze off at night to the audiobook (having set the sleep timer of course) with those weird and wonderful concepts swimming around in one's head. Best way to learn.
Perfectly narrated by Jeff Forshaw one of the authors so that the emphasis is on the key parts of the sentence that matter.
Highly recommended, would just like a couple pages PDF of some of the fomulae and graphs, although none of it is too complicated in words, some of us are more visual and helps with the learning process to see it presented that way.
Super stuff.

great listen

only problem is that some of the derivations are hard to follow with all the formulas thrown around, would be much better in print for those sections
