Summary: This book was a mixture between an abbreviated biography of Albert Einstein and a discussion of how he came up with his theories. It is pretty good at explaining any physics that it included in the book, and was not at all difficult to understand for a complete layperson on the subject.
My Thoughts: I enjoyed this book quite a bit. It’s my second book by Kaku, and I plan on reading more of his work. His science is quite approachable and he keeps to interesting topics.
