Basically, this could very well have been the book Einstein would have written, had he had the time to do so. It shows how the Grand Universal Theory is more like a Generic Underlying Tapestry, that shows up in multiple aspects of reality. That, and the concept of Infinite Multiple Realities make this 77 page illustrated book an interesting read.
