I found the book easily readable but didn't give me any new information. As a popular book it has to be simple and cannot go into much depth so I had already picked up what it had to say about quantum physics. Towards the end of the book it moves to using vague illustrations rather than proofs that the universe does not need a cause and to introduce M theory as something that could possibly explain things. He states that no one knows what M stands for and, having read the relavent parts several times I have little idea what it is. There certainly is no solid proof and the idea of gravity spontaneously generating something when there was no gravity is left so vague that I suggest M stands for myth. Stephen Hawkings is undoubtedly a brilliant scientist but the statement that philosphy is dead seems to be a statement of philosophy that suggests that he has moved from an unbiassed scientific.
