The first couple pages of Seveneves certainly does not impress, but maybe I'll like it better after reading the whole thing.
My wife read my copy after me. If I remember correctly, she more or less read up to that scene in 5-10 page increments, and then read from that scene to the end in most of one night.
That was, bar none, the best reading experience in my life.
With respect to Anathem in particular a lot of the problem is you didn't really understand what was going on for quite a while and I found that made it a bit of an effort to keep going.
Damn, I need to read that one again. It's been too long.
I kid, I kid. I ended up loving Anathem too, although I seriously struggled to get going.
I remember around the 200-page point thinking, "ok, now we're getting started."
Man, no kidding. It feels like a very inelegant info dump. While I realize those tend to show up in Stephenson books at some point or another, it's a rough way to start.
I liked a lot about Anathem but found Reamde unmemorable. I'd love to see a return to form.
Reamde was a dud for me as well.

“But there’s a theory that some of them were created shortly
after the Big Bang. The universe was lumpy. Some of the lumps
might have been dense enough to undergo gravitational
collapse. They could form black holes that instead of
weighing what a star weighs could be a lot smaller.”
“How small?”
“I don’t think there’s a lower limit.”
Yes there is. Black holes lose mass by Hawking radiation: http://en.wikipedia.org/wiki/Hawking_radiationA black hole smaller than 0.8% Earth masses loses more mass than it gains from the cosmic microwave background, and will eventually evaporate.
http://arxiv.org/abs/0908.1803v1 (See the table on page 15)
The lifespan of a 108,000 tonne black hole is ~350 hours. At that mass, its event horizon is .32 attometres across, and the Hawking radiation it emits is measured in gigaelectronvolts.
I assume your point is that a GeV is a minuscule amount of energy, which isn't going to push 130kT around at any speed.
you're quoting a speculative paper.
Hawking radiation has never been directly observed, but it is generally presumed to exist. I haven't read the story extract, but I assume the plan
would be to bleed matter into the micro black hole to
maintain it.
Read the story. In context, the character is talking about how small a natural, primordial black hole can be. There is an obvious lower bound, due to Hawking radiation. I assume your point is that a GeV is a minuscule amount of
energy, which isn't going to push 130kT around at any speed.
Read the paper. That's the pseudotemperature of the event horizon. It's so hot that it's glowing largely in ultraenergetic gamma rays. The total power radiated by a .32 attometre black hole is 5,519 petawatts."The only part that gave me any trouble was calibrating an ending that would leave the reader satisfied that the story had concluded while leaving the impression of an open-ended world."
Surprise! Still can't write endings. It's okay Neal, it's what we've come to expect, and we totally love you anyway.
Reamde was pretty good, and this is an interesting setup.
Edit: Anathem not Anathema (thanks __david__ and lmm)
You my friend, have missed out big time.
I'll see if I can check out Anathem at some point, but Baroque is really too much of a commitment for me. I'm a slow reader.
Edit: Anathem not Anathema (thanks __david__ and lmm)
Books I've liked recently that have done that sort of thing: Rainbows End, or if you're willing to venture a little further in genre then Stardust (by a different Neil).
It's less ambitious than most of his work, sure. But it is a lot harder to create a gripping and memorable book set in the present day, written in a conventional style, and without the benefit of speculative future technologies.
With REAMDE he pulled it off, though.
I have read a lot of light thriller-type novels in my day (mostly bought at airports in the pre-Kindle era, admittedly), and they are usually pretty hard to care about. Not so with REAMDE, though.
[1] Anathem is in my Kindle queue, and I couldn't stay interested enough to get through the Baroque Cycle. Have read the rest, though.
For me it's in his top three books along with Snow Crash and Diamond Age. It's also on a very short list of "books I will definitely read again at some point".
If the Baroque Cycle doesn't appeal up front, you're probably fine skipping it. I liked them, but I really had to push myself through large parts of each book. I kind of felt like they needed to be edited down a bit.
I've intentionally not read this teaser, but from he blurb I feel like I'm going to like Seveneves
My theory has been that after Diamond Age he got to famous and/or no longer had an editor that said: this is OK. Cut from 1500 pages down to 450 and this could be great.
Judging from this thread Anathem might be worth a look. And this excerpt doesn't look half-bad either.
The book biz isn't as bad as movies, which are made or broken by their first 48 hours of box office receipts, but 80% of sales still occur within 3 months of publication (in hardcover, with a similar bounce when the book goes paperback). First-week sales are what count for (a) bestseller list presence and (b) bookstore re-orders based on (a). And pre-orders count towards first-week sales!
With this particular book it would be a safe bet, I've read all his books, even REAMDE twice, which others didn't appear to find as compelling. But I don't like even the concept of pre-orders on general principles, although fiction publishers don't abuse them as badly as other i.e. game publishers (http://www.reddit.com/r/gaming/comments/2s6zgz/stop_preorder...) I still prefer not to participate.
edit: http://www.amazon.com/Seveneves-A-Novel-Neal-Stephenson/dp/0... gives a bit more detail and it is likely it will not become a ring. Probably a lot of highly energetic reentrant debris capable of generating a lot of atmospheric heat.
edit: @jaquesm - i'm allowing for creative license, and was making guess explaining what would happened based on my gut feel for the plot direction. you're probably correct on the physics.
What reason would there be for the moon debris to form a cloud, that would require a lot of energy added to the pieces after the initial collision to get them to go into other orbits? (I'm sure Stephenson has researched this but it makes no sense to me at first sight.)
The options really are quite limited, re-unification in a 'lump', one or more large chunks escaping earth orbit or a ring, I don't see how a cloud is possible.
All but the second would result in quite a bit of debris landing on earth as the debris from the collisions would be scattered in all directions.
On the other hand, the moon is beyond earth's Roche limit so I don't think the final result will be rings.
Also what is the tensile strength of the center of the moon? I'm not sure it's possible to have 7 large non-spheroidal shaped pieces, but google suggests ~800 km is the lower limit for rocky bodies, so maybe it's just possible.
“Not now, Pa, I know the moon’s pretty, I’m right in the middle of debugging this method . . .”TIL that "with out" is two words.
(I mean, seriously. How do you screw up your very first sentence?)
