A landmark volume in science writing by one of the great minds of our time, Stephen Hawking's book explores such profound questions as: How did the universe begin--and what made its start possible? Does time always flow forward? Is the universe unending--or are there boundaries? Are there other dimensions in space? What will happen when it all ends?

Told in language we all can understand, A Brief History of Time plunges into the exotic realms of black holes and quarks, of antimatter and "arrows of time," of the big bang and a bigger God--where the possibilities are wondrous and unexpected. With exciting images and profound imagination, Stephen Hawking brings us closer to the ultimate secrets at the very heart of creation.

A brief history of time is a very informative book that talks about complex topics in terms that most people will easily understand. I think that Stephen Hawking is very good at writing down his ideas and theories and explaining them, despite not being able to speak. I think that the concepts explained in this book are very difficult to quantify, since humans simply cannot process some of the mechanics and the sheer scale of the universe. Stephen manages to explain advanced theories using terminology that does not require pre-existing knowledge to grasp. Despite this, though, there are some things explained in the book that did not make sense but I found that it was important not to question but to follow Stephen throughout his explanation, and this helped me grasp the topic he was discussing. However, there are some topics that Stephen cannot explain in layman’s terms. For example, how can you expect someone to explain a singularity in simple terms that everybody can understand? This is my only problem with this book, since it aims to educate people on topics that are hard to understand using a simple method, and yet it struggles to explain the topics mentioned.

I rated this book a 4/5 because it is more difficult to understand than it should be, since it aims to educate everybody on astrophysics. Apart from that, I think that this book is an excellent read and I would recommend it to everyone that is above the age of 14.

I love this book. It's not technical enough for the scientists and it's too complicated for many of those without at least a basic understanding of physics.

Professor Hawking does a fantastic job of using analogies and imagery to explain some of the most complex ideas in physics, mathematics, and astronomy.

It's not meant to be a science textbook, so keep looking if that's what you're interested in. It's also not an easy read if you aren't familiar with the fundamental concepts of physics.

I found most of this book to be unintelligible. I have a brilliant mind compared to some
of the ridiculous comments here. One would have to be an astrophysicist to really have any
understanding of the material.

For example, waht is imaginary time? Everything here is theoretical, mainly because they
do not fully understand the origin of the universe. These are educated guesses. Ask someone
to define a singularity in layman's terms. They cannot

"It's turtles all the way down!" will probably be an iconic line for me for the next bit. On my own, I would have never thought to ever read this. I am very thankful for my friend who was an inspiration to me in her brilliance and sort of recommended it. Throughout the "brief" explanations, I felt a little muddled over some parts. However, I found that overall I thoroughly enjoyed all of the mystical and fascinating explanations of theories and ideas. For a high school student, this may be a bit of a struggle so I suggest having a bit of physics background (and science) before proceeding in reading this.

The problem with popularizations is that something gets lost in the translation. At best, A Brief History of Time reminded me of the predicament of Nuñez in H. G. Wells's "The Country of the Blind." Hawking's doctorate and subsequent work validate his own understanding. His later popularizations may have fewer problems. For now, based on this, his first mass market book, my judgment is that Hawking's knowledge of quantum relativistic physics is impossible to transmit to those of us who know so much less.

I marked the book up, noting errors and omissions, beginning with the history of philosophy and the history of science. I also tagged contradictions within the text. Worst, he seems not to know at least one fundamental fact (concerning time dilation) about black holes. It may be that in trying to explain the very difficult in very common language, the ambiguities are unresolvable. Toward the close, Hawking laments that modern philosophers have retreated from the physical world explored by Aristotle and Kant, and, following Wittgenstein, they worry more about the structure of language (p. 174-175). That might be the more relevant concern, considering Hawking's disrespect for Aristotle and endorsement of Kant coupled with the very many problems in his book.

Hawking seems to confuse chaos, randomness, entropy, and order. He seems to have a high school understanding of imaginary numbers. Or maybe it is just that he expects his readers to be at that level, but not beyond. And, the blame may best be directed at his publishers who told him that each equation in the book would reduce his readership by half. So, the presentation was dumbed down to level of gee-whiz and good-golly as we gaze like slack-jawed apes at the mind-numbing marvels of our incomprehensible universe.

I am a 6th grader, and I have came here after reading last book in the Accelerati Trilogy (Hawking's Hallway) by Neal Shusterman and Eric Elfman. I must say, I am very intrigued by all this space-time continuum and time travel and stuff like this. For people who love this book, I recommend you read the Accelerati trilogy. You will love it.

Some people never admit that they are wrong and continue to find new, and often mutually inconsistent, arguments to support their case - as Eddington did in opposing black hole theory. Others claim to have never really supported the view in the first place or, if they did, it was only to show that it was inconsistent. It seems to me much better and less confusing if you admit in print that you were wrong.

We find ourselves in a bewildering world. We want to make sense of what we see around us and to ask: What is the nature of the universe? What is our place in it and where did it and we come from? Why is it the way it is?

 A Brief History of Time by Stephen Hawking is a book about of a history of the universe, for my opinion is something amazing this book, shows how the ideas of the human was changing that first start with  Aristotle who thought that the earth was stationary so the earth didn’t move and the planets,the sun and the stars was moving around the earth,and to finish Hawking with his big theory about blacks holes that it is something awesome. For me the most impact it was when I understood how the big ideas were changing  to understand better the world.
    From my point of view the best scientist has been Stephen Hawking, he is a scientist who everybody should admire because he is a disable person, but he is really smart, also he has the same respect that Albert Einstein, he has a real goal that he said “ My goal is simple. It is complete understanding of the universe, why it is as it is and why it exists at all”. In my opinion this “goal” is something unbelievable, this is why he is so smart but he has a problem or something that for me it isn't okay that he is atheist; Although,he wrote a letter where he told that God was always in the equations,It was my conclusion about his letter.
    The book A Brief History of Time let me feel without knowledge about this theme,   because in the book explain everything in the universe in my world specifically. I could discover something that I didn’t know, but I always keep asking me the same question.One part told about the blacks holes that  I don’t like just because our mathematics are excellent, but the technology of the humans can’t travel  to the galaxies to test all theories that we have it.
