First published in 1988, Stephen Hawking's A Brief History of Time is a landmark.

Stephen Hawking s phenomenal, multimillion-copy bestseller, A Brief History of Time, introduced the ideas of this brilliant theoretical physicist to readers all over the world.

One of the most influential thinkers of our time, Stephen Hawking is an intellectual icon, known not only for the adventurousness of his ideas but for the clarity and wit with which he expresses them. In this new book Hawking takes us to the cutting edge of theoretical physics, where truth is often stranger than fiction, to explain in laymen's terms the principles that control our universe. Like many in the community of theoretical physicists, Professor Hawking is seeking to uncover the grail of science - the elusive Theory of Everything that lies at the heart of the cosmos. In his accessible and often playful style, he guides us on his search to uncover the secrets of the universe - from supergravity to supersymmetry, from quantum theory to M-theory, from holography to duality. He takes us to the wild frontiers of science, where superstring theory and p-branes may hold the final clue to the puzzle. And he lets us behind the scenes of one of his most exciting intellectual adventures as he seeks "to combine Einstein's General Theory of Relativity and Richard Feynman's idea of multiple histories into one complete unified theory that will describe everything that happens in the universe." With characteristic exuberance, Professor Hawking invites us to be fellow travelers on this extraordinary voyage through space-time. Copious four-color illustrations help clarify this journey into a surreal wonderland where particles, sheets, and strings move in eleven dimensions; where black holes evaporate and disappear, taking their secret with them; and where the original cosmic seed from which our own universe sprang was a tiny nut. The Universe in a Nutshell is essential reading for all of us who want to understand the universe in which we live. Like its companion volume, A Brief History of Time, it conveys the excitement felt within the scientific community as the secrets of the cosmos reveal themselves.
A Brief History of Time by Stephen Hawking is about modern physics for general readers. Its aim is not just listing some topics, but introducing modern physics by examining current scientific answers, although not complete, to fundamental questions like: Where did we come from? Why is the universe the way it is? Was there the beginning of time? Is there an ultimate theory that can explain everything? We don't have such a theory yet.

I have read the first edition when I was a high school student around 1990, and this book is the revised version (revised in 1998). Compared to the first version, there are little changes. But there is one noticeable change in his point of view on the ultimate theory. According to him, recent findings on "dualities" seem to indicate that it would not be able to express an ultimate theory in a single fundamental formation. Instead, we may have to apply different theories to different situations, but in the areas which they overlap, they must coincide.

The book has a lot of merits. Firstly, non-native English users including myself would feel comfortable and find it easy to read. He doesn't use difficult words and his writing style is clear. In the sense, he is better than other English scientific authors like R. Penrose, J. Gleick and I. Stewart. Secondly, the level of the book is well-chosen for general readers and the total page number is just less than 200 pages. If they read the book, at least, they would be able to learn more about how the universe began, how the stars have been formed, and how we have come here as the result of the evolution of the universe. More than that, the book contains interesting stories of some Nobel Prize winners in physics with their results related to the mentioned fundamental questions. This will help readers understand the 20th century's progress in physics.

Thirdly, among the physicists who have contributed in searching an ultimate theory, the author himself is distinguished. He showed that a black hole radiates light, so we can say that a black hole is not completely black. Up to the time he presented this theory, everyone believed that a black hole can only absorb everything around it, but radiates nothing. To find the ultimate theory, we have to consolidate general relativity and quantum mechanics, but the two theories are inconsistent in many cases. But Hawking skillfully applied both of them to black holes, and obtained the result. The physicist, L. Smolin regards his finding as a starting point toward the ultimate theory. That we can read a book where Hawking himself explains about his theory for general readers is thrilling.

As I mentioned above, this is my second reading of the book. When I first read the book as a high school student, it was impressive for him to explain that at the beginning of the universe, there was a singularity where the energy density is infinite, and so the law of physics including general relativity, cannot hold. But at the second reading, I found out that what Hawking really wanted to say was not that we cannot know the beginning of the universe, but that we need another theory that can explain the beginning by considering both general relativity and quantum mechanics. Actually, in the book, he introduces his "no boundary" theory which explains it without the singularity. But this theory has been neither verified nor disproved by experiments until now.

Here is my advice for a reader. Don't think that you have to understand every word and sentence. Less than 200 pages, the book contains a lot of things and the author does his best in explaining them easily. For example, its explanation about the history from the beginning of the universe to the first living things on earth is outstanding. And about time travel, its arguments are ever clear and reasonable for me. But, in a few parts, the explanations are just sketchy, so if a reader is not already an expert, he could not fully understand them. When you meet such parts, just move forward. The most important thing is to learn some things and enjoy the reading.
Frankly I'm unqualified to rate this. Thus, it gets a 5 star to avoid doing it a disservice. While considering myself fairly intelligent, it's evident I'm not in this league. Having read and understood all of the words in this book, I just do not have a firm grasp on much of what Mr. Hawking presents. The concepts, proofs and theries are beyond my ability to comprehend. He makes a great attempt to reach the non-scientist reader. A really good job; a terrific effort. But this reader wasn't up to the task.
I read this book with my oldest son (13 almost 14 years old) and enjoyed it even more than when I first read it in the 90s. Stephen Hawking is a brilliant writer. His knowledge of his field (theoretical physics) is vast, deep, and emotional. His ability to distill complex ideas into accessable analogies rivals Richard Rhodes (who brilliantly describes Mad Cow Disease in Deadly Feasts and the atom bomb in Atomic Bomb), whom I consider to be the best in class for this ability. I had no appreciation for Dr. Hawkings' skill when I first read this book - probably because I skimmed it. :-)

This time around, my son and I read a chapter a day and discussed it, first with each other then including my husband, the resident Big Brain. Talk about rewarding! My experience with reading this book with my son has been so positive that we are looking forward to reading the Feynman Lectures together, this time with my husband, this fall. Who knows, I might become an accidental physicist. LOL
If you want to know how the world and the universe works then this book is certainly the one to read. From Quantum Mechanics, providing key sight into extremely small particles and matter that makes up the universe, to relativity (general and special) which describes how space and time works is what this book is all about. What I liked most was Hawking's writing style where he inserts both humour where required (he opens with the Turtle challenge by a member of the audience) as well as plain and easy language to explain concepts about complex topics. Whilst the detail went a little over my head it was nice to go through and pick out areas that made sense. Then again I was able to read a GetAbstract summary on this book and get more out of it. It really depends on what you want to learn and how much.

Three key takeaways from the book:
1. An expanding universe does not preclude a creator, but it does place limits on when he might have carried out his job!
2. The universe is expanding by between 5 - 10% every thousand million years.
3. The police make use of the Doppler effect to measure the speed of cars by measuring the wavelength of pulses of radio waves reflected off them.
