A most interesting book. Hawking envites the reader to look in the universe in its most deepst way: though physics. Though the book is not specially easy to read, Hawking managed to describe the most important achievements of modern physics in a very short and compact book. For anyone that is inerested in physics a must have ! His brilliant mind makes complex topics from physics such as quantum mechanics and relativity quite understandable. All without a single mathematical formula ! He discusses every topic only in its physical meaning rather than through mathematics. Also for people interested in philosophy, a reference for understanding how modern science "sees" the universive in its very essence, from the beginning to its end. If you want some answers for such questions like: what is time ? What is Space ? When was beginning ? Is time travel possible ? What is the fate of the universe ? This is the book for you.
