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. I strongly recommend it to anyone who is a fan of Stephen Hawking. 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. Wells's "The Country of the Blind. 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. 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 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. This book was very enjoyable and introduced me easily to some of the hard concepts of modern physics. XuanAmanda thinks this title is suitable for between the ages of 11 and 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? Skip to main navigation Skip to main navigation Skip to search Skip to search Skip to content.
