Einstein’s explanation of special relativity left me feeling warm and fuzzy, but when he moved on to the general theory, things took a turn for the worse. I’ll be the first to admit that a failure of information flow from Einstein to me is most likely a problem on the receiving end. However, in this case, Einstein completely left out important parts of the theory. It was as if he tried to explain a bicycle by describing the front wheel. Perhaps he felt that explaining the whole bicycle without leveraging concepts from elsewhere in physics and math was not possible. That may be true, but it doesn’t change the fact that reading this book isn’t going to give you even a basic understanding of the general theory of relativity.
