In general, this book shows that theoretical physics, at least in the field of black holes, is more an experience of thought, logically based on the mathematical language, modeling a reality if as is that one can define the profound reality of the universe. Specialist in string theory, the author demonstrates a humility about the potential of this theory, unlike Brian Greene ("the elegant universe").
Although there are lengths (the book teaches so many elements), its drafting reports of a performance and an undeniable talent extension.
Read more ways than one to assimilate the best theoretical elements provided (despite happen to understand the quality of extension seems a real challenge).
