Lol. Enjoy by all means, far be it from me to come between a man his god and his constitution.

Who said I was talking about my constitution? Maybe the thread title "Hawking Comes Clean" was more descriptive than anyone initially realised.

Review of Hawking's book in today's NYT: Many Kinds of Universes, and None Require God

I wasn't very impressed with "Brief History of Time" and I don't expect to be bowled over by his latest book either.
Hawking is quite a self publicist in his own way and the attention accorded to his books reflects that as much as their scientific or literary worth.

what's wrong with it? I suspect a certain "not invented here" pooh-poohing from certain US quarters, but I haven't read either the first book nor this new one (which was roundly denounced before anyone had even read it by certain factions).
"the god delusion" for example by Dawkins was a very easy read, very informative and straightforward. Hawking on the other hand discusses math, which is confusing at higher levels at the best of times...

Brief History was born out of extreme necessity (for cash) - it was his two great results with a wrapping of fundemental cosmology. He has never been the best instructor or lecturer but he does capture the imagination, and the confusion he weaves at his public lectures seems to be well received!

Does Hawking really use the terms "laws of physics" (or "laws of nature") and "universe" as interchangeable?quote:OK, I think I understand and agree with your complaint. I had claimed (and quoted MacKay and Lennox) that scientific law is descriptive. But Hawking's use of the term seems a bit different. I think we often use the terms "scientific law" or "law of physics" in two closely-related senses: 1) Our scientific description of the way the universe behaves 2) The behavior of the universe which we are trying to describe scientifically Hawking's use above is closer to the second. The universe behaves in a certain way, we study this, we describe it mathematically and give it a name, "gravity."
quote:No, I don't work in quantum gravity, and I've never studied quantum cosmology, even though I did my thesis in an astrophysics group. I am an experimentalist, and I work with experimentalists, some of whom do experimental astrophysics (sky surveys, dark matter and dark energy searches, etc.). I know some folks who do simulations of binary star collapse, but I don't know much about their research. "Science without religion is lame, religion without science is blind." — Albert Einstein I am very astonished that the scientific picture of the real world around me is very deficient. It gives us a lot of factual information, puts all of our experience in a magnificently consistent order, but it is ghastly silent about all and sundry that is really near to our heart, that really matters to us. It cannot tell us a word about red and blue, bitter and sweet, physical pain and physical delight; it knows nothing of beautiful and ugly, good or bad, God and eternity. Science sometimes pretends to answer questions in these domains, but the answers are very often so silly that we are not inclined to take them seriously. — Erwin Schroedinger

I'm not exactly sure what it is - maybe something to do with his writing style. I've got a book by Roger Penrose and, even though it's full of maths and I don't understand the vast majority, it still manages to capture the imagination and seem exciting in a way that Hawking's book totally failed to do.

Funny, I really enjoyed Brief History of Time, but then I had the version with all the pictures.
As a teenager it made a big impression on me and really cemented a love of science. Maybe I ought to go back and see if it's held up.

I'd be interested to know what you make of Brief History of Time" now.

John Gribbin's books did {t}hat for me in my formative years. Had a look at them recently ("In Search of the Big Bang" and "In search of Schrodinger's Cat") and found them both incredibly tedious Same here - both were on my 'most read' books along with Lord of the Rings. Picked up in Search of the Big Bang about a year ago and gave up out of boredom. Is it because I was so familiar with the work? Or just because the ideas are quite 'tame' these days? Or was I just so taken aback by the ideas as a teen I would've obsessed over any half decent book scattered with Minkowski and Penrose diagrams and I've just read much better since?

After wading through an explanation of physics basics and the history of related subjects more generally I didn't find that there was much more to these books. Familiarity of the subject matter and the fact that I have read superior and more up to date accounts of this stuff elsewhere I think must be what has led to my changed attitude to these books.
But back in the day I really did find them quite inspirational. As a mate put it to me when I confessed a similar disappointment upon seeing the first Star Wars film again recently: "Well the film itself hasn't changed in over twenty years. So I guess you must have". Difficult to argue with that analysis really.

I've never read any other book by John Gribbin, but I enjoyed Schroedinger's Kittens. He wrote it as a kinf of sequel to In Search of Schroedinger's Cat, so it assumes a bit mroe knowledge and the general introduction to quantum mechanics is fairly brief, if I remember right. It spends more time talking about the philosophical implications of quantum theory - what is the actual physical reality that our maths describes?; is that knowable or important?; that sort of thing.
I think the question the book tries to address can probably best be summed up thusly: "Okay, so I know that it can behave like both a wave and a particle, but what actually is it, really?"
