I read it and thought it was relatively transparent. I don't know how transparent it would be to the layperson who hasn't at least tried to struggle with Hawking and Thorn and Greene's own book.
A layperson's opinion...
Well, I liked the slide show...
Seriously though I just can't wrap my mind around that stuff. If that makes me an ignoramus, so be it.
Human behavior, that's my gig. While you science guys go down the black holes and come back out again, I'll be counseling your families and friends. Takes all kinds, right?
Brian Greene
I've seen Brian Greene speak before. He's a really good speaker, but he does seem to have a preference for style over substance (even when talking to physicists).
Rumor has it that he left Cornell to go to Columbia to chase after a girl? (Of course, at least he didn't have a creepy German postdoc following him around, as one of my students did at a recently-concluded conference. She seems to be taking it in stride.)
On a completely different note, take a look at this: http://www.math.gatech.edu/~mason/research/foxtrotbcs.gif
