Brian Greene accomplishes it all in one sweep: he tells an enjoyable, enthralling story - a real page turner - and he gets a thoroughly complicated message accross even to non-trained readers. My background is that of an electronics engineer, with only basic training in quantum mechanics. As Dr. Greene mentions a few times in the book, maybe it will take two or three (or more, depending on your background) readings to be able to fully digest it all, but even if you read it only once, it suffices to put you up-to-date with the advancements (and, still, some shortcomings) of string theory in the direction of the TOE.<br><br>I am excitedly waiting to see some of the expectations of the scientific community regarding string theory confirmed (or not) in the coming years - and the best part is, I feel certainly able at least to follow the results, after having read this masterfully written book.<br><br>If you are, like me, one of those astronomy fans whose first contact with astronomy and cosmology was Isaac Asimov's "The Universe: From Flat Earth to Quasar", then felt delighted with Stephen Hawking's "A Brief History of Time", then I strongly recommend that you pick this one up as a worthy sequel to those masterpieces.
