Title: Vaporware
Review: This book, and string theory itself, is like the ultimate software demo: very slick, glitzy, claims to do everything, will solve all your problems, makes you want to go place an order for the product right now. Only with a little digging do you find out that the engineers haven't even written a line of working code, and haven't even figured out how to implement the basic algorithms. My advice: wait for the beta version.
