Query: sorry I spent money on this

The book's title and conceit piqued my interest, but I should have read more than a few pages before buying it... what a dull book!! There are a few interesting ideas in the intro, but the rest is just rambling and LOTS of unrelated (irrelevant?) references. I'm obsessed with einstein, but I couldn't get through this; it was excruciating reading.the book is more about the author's distaste for the field of physics than it is about einstein; he spends so much time rambling about physics in general, that you have to wade through pages and pages just to get to any einstein-related information -- and even then you don't know whether to trust it or not.my grasp of relativity is pretty basic, but the sections on relativity are misleading, and in at least one instance I caught the author in a basic error... after that, I just put the book down and gave up.
