IMHO this book achieves exactly what it sets out to, which is to provide an enjoyable background to Einstein's most famous work. Skipping between key points in Einsteins life, light-weight physics and the social-life of certain noteable physicists the book is always entertaining even if some of the physics is flawed. Despite these flaws the book provides a very readable introduction for the layman and the physics coverered (such as it is) will be more than sufficient for 90% of people. The remaining 10% (those with a physics background) shouldnt be reading this book, the rest will come away knowing more than they did before!
