Even with the relatively short amount of words used in this book, I couldn't keep interested. The short quips about relativity are the same old textbook stuff that you read and re-read in countless other more entertaining books on Einstein. After reading 100 pages into this book, the intrigue of Einstein's brain became less and less. Afterall, it was the man that was extraordinary, not his anatomy.
