Kaku runs away with his metaphors sometimes, and I felt like there was a lot of repetition, but all in all this is a pretty good intro ride through some higher-dimensional theories.

I read Kaku’s 2005 book “Paralell Worlds” before I read this. But after reading it I liked the way he presented the subject matter so much that I went back and read this. If you liked this then you will like Paralell Worlds as well, even though the subject matter is more or less an update of this stuff there is definitely a lot that has changed in the theoretical physics field. I recommend both of his books to anyone who is even mildly interested in the subject, I think you will be more interested after reading this.

Or if you just want to broaden your view on reality, read this, or take some good acid, or do both.
