Well, everybody's reviews, and its 4.3 average rating make me pretty sure I'm missing something here. Maybe I just wasn't in the mood for this book right now, but it seemed to go in many random directions. I thought I was going to get some good Scrabble words out of it, anyway, but iglu and aglu aren't legal.
The book goes over the wildlife, then the history of the various Eskimo (sic) groups there, then touched on oil exploration a little, then the history of European conquest of the Arctic. I kept hoping for sweeping passages that would conjure up gigantic walls of ice that would make me feel cold and fearful, but that never happened. ]]>

I guess you need to be the group mod to do that? ]]>
I know there's a list for Best LibriVox books - but I found a list called Best Free Audiobooks - http://www.goodreads.com/list/show/418.B...
I'll be listing some excellent LibriVox stuff there. I got Paul Coelho's The Alchemist, and what's-his-face's The World is Flat for free as promotions - I wonder if they count... ]]>

Greene explains relativity so I get it, quantum physics so I follow it, and string theory so that at least I get what it explains. For me, that's pretty good.
There are a few things in the book, layman though I am, that I know are already a little dated - he keeps referring to the age of the universe as 15 billion years, rather than 13.6 billion. Also, he talks about how some big expansion in the moments just after the big bang would explain how the universe is as big as it is, while gravity slows it down. The problem there is that a couple of years ago scientists realized the expansion of the universe is speeding up.
Then again, given that the book was written in 2000, that says a lot more about the rate of discoveries/new models in cosmological physics than it does about the book.
One thing that bugged me, that I suppose is my dilettante's misunderstanding of it all, is the models that seemed to be pulled out of somebody's butt, that because they could make numbers work in formulae, suddenly are 'proved.' Why strings? I understand (now) the problem in trying to reconcile Einsteinian physics with quantum havoc, but why strings? Why not teeny little clouds, or starfish-shaped thingies, or anything else?
Another thing - he consistently talked about a bunch of extra spatial dimensions beyond the 3 we're familiar with (that make the numbers work), but he talked about those dimensions being really small and curled up (small as in Planck length which is about (squeezes fingers together) thiiissss big). Isn't it more proper to say that our extent into that dimension is curled up and tiny? If I imagine a little picture of a bunny rabbit in a Euclidean plane, the two dimensions of the Euclidean plane aren't small and bunny-like, only my drawing is. If the drawing is on a very thin piece of paper, the dimension of height isn't tiny, only my piece of paper's extent into that dimension is.
But that made me think, well, if the universe is all there is, there's no 'ether' in which to sit and observe our universe's tiny forays into the 9th dimension, maybe the 9th dimension is tiny - it's meaningless to talk about anything else. Then in the last chapter he talks about multiverses, and maybe there are universes that expand out in the dimensions we don't but are tiny in ours, so then I thought I was right again. Plus I got the munchies real bad - I totally could have eaten a Dorito pizza.
Tangentially, this book made me spend some time trying to visualize a 4th spatial dimension. It, like many layman discussions of physics and universal models, uses the weasel-worded assertion that 'it's nearly impossible to visualize a 4th dimension at a right angle to each of the 3 we're familiar with.' Look, is it possible or not? If it is, I want to see it in my mind. Some guy on a message board says he can visualize a tesseract, so I have to believe him or not. In the meantime, I'm going to keep looking around different corners to see if any of them go off into the 4th dimension. ]]>
