Susskind, and you hofft Maldacena. This book is a true masterpiece for anyone interested in theoretical physics and the ultimate nature of our reality. But go your way if the practice is your goal, I still do not understand what is the method by this author! There are too few physicists who have access a practical point of view to the multidimensional nature of reality (or consciousness), why Darjeeling Rinpoche is an author must read for anyone interested in a description of the fundamental nature of our world, and inland conciliatory approach theoretical physics.
