I was bought this book as a Christmas present last year after seeing it here on Amazon and putting it on my list for santa ;)
This book is a fantastic read for anyone interested in the paranormal who thinks about the reasons why we continue to experience strange occurences the world over. The book covers M theroy and string theroy (as well as many others) and gets you thinking about the quantum world around us.
I would reccomend this book to anyone, however it may be worthwhile reading other titles to get a good grounding on the basics of quantum physics, though saying that, the author does go into some great detail when explaining her ideas.
A word of warning though. You may not want to read this book before you lay down to bed as it will set your mind racing thinking about the implications of the quantum world. Great read!
