This book is a tough one to get through because of the deep subject matter but it tells the fascinating story of important scientific advances during the last century. It chronicles the work of Einstein, Heisenburg, and Hawking. If you are looking for a good explanation why most scientists believe in the Big Bang this is your book. In addition, Hawking describes his no boundary proposal which attempts to do away with an absolute singularity in the beginning of time which reduces the role of God as the immediate cause of the universe. This book is very good and a must read if you are interested in origins
Stephen Hawking is known to the world for both what he can do and what he can't do. What he can't do is most of the things you can. He suffers from amyotrophic lateral sclerosis, a nerve disease that has left him with little more motor function than a rag doll. He can move his hands a little and talk only with the aid of a voice synthesizer. His mind is apparently unimpaired--to put it mildly. Despite his handicaps he is considered one of the world's leading theoretical physicists. The man who can't use his body to scratch an itch uses his mind to explore time and space, to explore quantum mechanical particles and the shape of the universe, to see back to the Big Bang and forward to the death of the universe.
Well now coming to the point.
Its a small book.
Its comprehensibility is spotty.
It uses some questionable philosophical points. It seems he is building explanation for why you know universe might not have no boundry in space & time. The anecdotical references he gives complecate the stuff. It may well be that with the mathematics his heuristic arguments would be more convincing, but without it much of his reasoning is most unconvincing.
Seeing his genious & busy life some times i feel he might have delegated the job of bringing these theoritical perspectives to masses to someone like us.
The book has a useful glossary, though incomplete and also some definitions sound confusing.
Though i feel it s a readable book, but fundamentally it seems flawed. But we all know that people can only relate to what they understand & he also points that out in the book so still its a decent book if not great.
Ultimate Conclusion: A read once.
