Bertrand Russel was an excellent writer, and one of the few philosophers who truly understood relativity. This book is also a classic. However, the book attempts to explain relativity to the layman using "text" only. The book is not mathematical, and it contains very few graphs or diagrams. This is not the best approach to explaining relativity. Good graphs/diagrams/images can to a certain extent replace equations. There are many modern introductory books and multimedia presentations that does a better at job at introducing relativity.

I recommend this book as a "classic", but not as an introduction to relativity for the non-physicist.

I think this book can justifiably be called ABZ of relativity. The author sincerely tries to tell us about relativity by building up from basic elements, but at the point it gets to the stuff that is supposed be really interesting, it becomes unintelligible for the less gifted. He gives three pages to tell us about the difference between mass and weight, but the central concept of "interval" is used for some pages before being poorly defined and explained. I am positively sure he understands relativity and all, and I am sure those definitions are correct in the strictest sense, however they didn't help a beginner, at least in this case. Having said this though, this book is still a very nice read and could be read even if only for its strange humor and wisecracks.

==========================================

The main stimulus to read that book was Bill Bryson's "A Short History of Nearly Everything" (2003) which I have recently finished. When dealing with the Theory of Relativity, Mr Bryson mentions Lord Russell's book as one of the most successful attempts for popular explanation of this traditionally difficult for the general public subject, but he casually adds the devastating remark "commercially at least". Having recently been rather hooked on Bertrand Russell, and having been more amused than fascinated by Mr Bryson's book, my curiosity about "ABC of Relativity" (1925) quickly reached the pick-up-from-shelf threshold.

Now, let's get one thing straight from the beginning: I have no intention to compare both writers. After all, to compare Bill Bryson with Bertrand Russell is like to compare bicycle with Harley Davidson. A singularly ludicrous business indeed. When Lord Russell was interested in a subject - be it relativity, morals, mind, matter, education, knowledge, society or whatever else you may think of - he wrote a book dedicated solely on the subject, not careless and flippant histories of nearly everything. All 60 or so books which Bertrand Russell produced during his almost century long lifetime will probably not give you as many facts and figures as Bill Bryson does in 500 pages, but a single essay by Lord Russell may well give you what Mr Bryson is quite incapable of: thoughtful, stimulating and penetrating reflections with quite a bit to ponder upon. Even in terms of literary styles - by far Mr Bryson's most valuable asset - Bertrand Russell's witty and perceptive writing is embarrassingly superior to the easygoing and superficial stuff Mr Bryson offers you.

So, after I have done what I have promised not to do, let's get to the point.

The point is that the theory of relativity is an immensely abstruse subject. Which is of course no excuse. If the theory is one of greatest achievements in the history of mankind - as is constantly claimed to be - there must be some way to be explained to the general reader in such a way as to grasp its great significance. Moreover, this significance must have some practical outcome for the people at large, for otherwise its greatness is greatly limited indeed. A scientific theory may explain a lot and make quite a revolution in some highly specialised circles, but if it is confined to them and have no real value for the ordinary man, such theory has to my mind nothing to do with greatness, except a purely scientific one which is of no real value for mankind as a whole.

Such is the case with Einstein's theory and me. I consider myself a reasonably intelligent fellow with a reasonably solid scientific background, though by means in the field of physics or astronomy, yet the theory of relativity - be it special or general - is still perfectly beyond me. Pity, because relativity in general plays an extremely, an inordinately huge part in my professional life. Everybody who has ever had the (mis)fortune to work in some of the numerous fields of molecular biology cannot have failed to appreciate the tremendous part relativity plays in the whole thing. Everything is relative here. What you measure matters not: you always compare it to a control, sometimes to more than one. It's a common joke around that some people believe in God, others have to show controls.

Notwithstanding the greatest admiration I have for the author, "The ABC of Relativity" has been my first disappointment with Bertrand Russell; perhaps not a major one, but a disappointment nonetheless. Despite that his style is as lucid as ever and every sentence makes a perfect sense, the overall effect I did find quite unsatisfactory indeed. It is still quite a mystery to me what is so great about the theory of relativity; perhaps its greatness is relative. Lord Russell's book is almost entirely devoid of mathematical horrors and was of course written especially for the lay reader, it is quite readable and does have several interesting points which might just convince me that the theory of relativity is not totally useless for me, but on the whole I remain a sceptic about its ultimate value outside the very restricted world of astrophysics. Sometimes, indeed, Lord Russell comes tantalisingly close to make some real sense of terms like space-time or their kinky intervals, but he never really ventures into the realm of the comprehensible. The matter remains thoroughly transcendental as far as I am concerned.

Interestingly, the book contains a very short preface by one Felix Pirani who apparently revised it no fewer than three times to include new scientific developments.The first two of these revisions were carried out with the approval of Bertrand Russell, the fourth happened 15 years after his death and was a sole responsibility of Mr Pirani. He also mentions that most revisions occupied the chapter about the expanding of the universe, whereas the purely philosophical content of the last two chapters was the reason why he didn't touch them at all. At any rate, Mr Pirani's revisions seems to have been minor and he can hardly be held responsible for any problems one might have with the book; indeed, most of his revisions are either too minor or too subtle to be noticed at all. Nor do I think that the pecuniary motives of Bertrand Russell to write the book, let alone any incompetence on his side, has anything to do with his failure to convince in the value of his subject.

For all his shortcomings, Lord Russell's prose is infinitely superior to the remarkable mess that Peter Clark has written by way of preface and, taken in proportion of its volume, way more rewarding than that of Bill Bryson. I am willing to believe that the legendary theory of relativity is either not so great when stripped of the purely scientific terminology or it is simply much too abstruse a subject to be put in any form for the general public - which is the same actually. Or perhaps I am (being) too obtuse. It might be that the theory requires a very special kind of mind which mine is not.

The theories of relativity developed by Albert Einstein are contrary to what we experience in daily life and a complete understanding requires knowledge of high-level mathematics. Therefore, in the years after the theories first appeared in print, few people had a complete understanding of what the theories were. However, presented using the proper analogies, it is possible for the layperson to understand a great deal of the principles of relativity.
This book is the attempt by British mathematician/philosopher Bertrand Russell to explain relativity to the masses. While the result is generally successful, the analogies are sometimes weak and more puzzling than revealing. If you are interested in explanations of science and relativity for the layperson, then my suggestion is that you read the popular science writings of Isaac Asimov instead. No one is better than Asimov at making science understandable and Russell lacks some of the necessary literary genes for expository writing.

I can't say I've read this book, but it was recommended by Neil deGrasse Tyson on a reddit.com Ask Me Anything interview.
