In 200 highly illustrated pages, Hawking is pushing the frontiers of popular physics beyond relativity and quantum theory, past superstring theory and imaginary time, into a dizzying new world of M-theory and branes. It's a colossal venture--one Hawking is uniquely qualified to undertake--but it is crammed into far too small a space. When you consider the other rather good tomes being written on the nature of consciousness these days, the decision to limit The Universe in a Nutshell to the dictates of publishing rather than to the natural parameters of the material is an unfortunate one.
Worse, Hawking tries to paper over the complexity of his field. He rushes over the very concepts he should be helping us understand, only to belabour simple ideas, often by means of flip Star Trek metaphors. Also unfortunately, the illustrations--by turns trivial and opaque--mirror the faults of the text. The author's name alone will guarantee sales, but the book we long for--the long, ruminative, poetic celebration of Hawking's world--seems as far away as ever. --Simon Ings

4.0 out of 5 stars
An enjoyable but challenging book,
By A. K. Johnston "(www.andrewj.com/books)" (LEATHERHEAD United Kingdom) - See all my reviews (VINE VOICE) (REAL NAME)
This review is from: The Universe In A Nutshell (Hardcover)
This is the long-awaited follow-up to "A Brief History of Time". It's quite amazing how some of the ideas around the Physics of the very large and very small have developed in recent years, and Stephen Hawking is determined to communicate them to us.He realises that this requires diagrams and analogies, since the mathematics is getting ever more forbidding. As a result, unlike a lot of books on modern Physics and cosmology, this one focuses on pictures and spatial representations. It's beautifully illustrated throughout, almost a coffee-table book. That said, Hawking hasn't neglected the text either - it's clear, concise and frequently humourous. The book starts with the key ideas developed in the earlier part of the 20th century, Relativity and Quantum Theory, but in the context of more recent experiments and observations, which makes it feel more contemporary than more historical accounts. The second chapter explains how these developed through to the 1980s, summarising the various attempts at unified "Theories of Everything". The book's central chapter investigates what we now know about how the Universe formed and developed, presenting a lot of quite new findings and concepts. After this, the going starts to get harder, introducing concepts like time travel through black holes, and the physics of the strangely-named "p-branes". You may need to read these several times, and understanding is by no means guaranteed, but Hawking rightly focuses on the key implications rather than the models themselves. The penultimate chapter is a bit of a non-sequiteur, looking at the evolution of human and artificial intelligence. It's a fascinating subject, well described and clearly of great interest to Hawking, but doesn't quite fit with the rest of the book. Finally, the book presents some of the most recent ideas of unified theories - branes again - and makes some sense of why such strange mathematical models are needed. I enjoyed this book, but I wouldn't pretend to have understood it all on a first reading. However, I understood enough to be convinced that Hawking is not only one of our time's great scientists but also, despite his disabilities, one of science's great explainers. If you're at all interested in modern Physics, I recommend this book...

Nutshells need Nutcrackers....,
By A Customer
This review is from: The Universe In A Nutshell (Hardcover)
in this colourful book.Hawking attempts to correct his heavily linguistic approach of 'a brief history' in a well thought-out attempt at presenting a more coherent image of our universe and our current level of understanding of it. In order to achieve this Hawking quickly guides the reader through some of the complex theories using careful and well-thought out language and cartoons and graphics that support the text along with reasonable summaries of the main findings. He is also keen to point out and highlight the relevance of each area in our overall understanding of the universe. Many of these concepts are however, despite Hawkins best intentions difficult and abstract being very different from the normal classical experience of humans living in the macroscopic world. Quantum theory, P-Branes, Spin Theory, Sum of Histories, string theory are all dealt with here. Hawking avoids the use of Mathematics in explaining these concepts but it is still inevitable that some of the theories and concepts are not suited to this light approach - often complicated points that require more background comprehension in the subject remain difficult to comprehend. Occasionally one is left puzzled by abstract sections that are not well supported in the rest of the book. However not delving too much into any one branch or area -does have its advantages; conscieness keeps the various branches connected and allow Hawkings overall image of the universe to form in the readers consciousness. This together with Hawkins frequent good humour also appear to capture the most important aspects of each area. If one can subdue the frustration of not fully comprehending some sections and trust to Hawkings guidance, one is carefully guided to a current cosmological understanding of the universe. Hawking seems to be generously aware of the difficulty in comprehending some of the abstract theories dealt lightly by him in the text and offers the reader a reading list at the end including a section on 'getting more technical'. I would recommend this book to anyone interested in gaining an overview and powerful insight to the current shape of the universe. Hawking covers well the many theories and concepts that are pre-requisites for the more recent discoveries and Hawking brings his own valuable insight and guidance to these without becoming too bogged down in technical detail. An excellent starting point too for anyone interested in finding some answers to some of the more fundamental questions asked by humans.

Excellent Summary, but Nothing New,
By A Customer
This review is from: The Universe In A Nutshell (Hardcover)
This book is said to be the inspiring sequel to "A Brief History of Time".It starts by two chapters discussing relativity and quantum mechanics, like repeating the old book, but with clear explanation of the concepts such as spin, time curve, forces, and string. A formula on the Black Hole Entropy closes these beginning chapters. It is something like S=Akc³/4hG :). Startin on pages 67, it discusses "new" topics. The history of the universe, which is not linear. Then prediction of the future, with some other formulas, one from Schrödinger, and two others about Black Hole again :). Then it flows to the possibility for time travel to the past (and whether then the history could be changed). The next chapter discusses the future, whether it would be Star Trek or not. Also discussed are DNA, AI, mikroprosesor, etc. A discussion on the philosophy of the universe closes this book. The chapters are linked well, but not sequential. Compared to many other popular science book published in the last 10 years, there is almost nothing new offered. But this book is a very excellent summary of all things discussed on those books (including the previous Hawking's book). We don't need to read his previous book before reading this one. The illustration is very rich, and luxurious. Many boxes discuss various topics from many other scientists, presented without making mess to the main text. Very recommended.
