While you are correct that water will preferentially suspend finer grains, sand is commonly suspended in any flow that's fast or deep enough. Sand blows through river systems pretty quickly on geologic timescales.
Your are right to point out, though, that this eventually ends up in rock again in some form or another. And this rock gets exhumed and eroded into big particles, some of which may break further down to sand, silt, clay...
So the answer lies in the fact that on earth, additional large debris is generated along with fine debris. On the Moon, it's the same stuff sitting around getting hammered over and over by meteorites. It ends up very fine and very pointy.
Nature, being a short-format and high-profile journal, is nearly impossible to write for in a flowing, style-conscious way. The short length requirement of the articles calls for extreme terseness and high information density, and thus high jargon density.
Your analysis would be better served by several different articles of the same, long-format journal.
You know a bunch of informed computer geeks who read Slashdot and maybe Groklaw and are enraged.
Your social circle (and mine!) are not representative samples of the general population. This stuff doesn't get mainstream coverage, unless it's paid propaganda by said evil organization.
Most mayors would not have shown the leadership that Giuliani did. See New Orleans, use the mayor or governer as examples. Not bad people, but simply not up to the task and not having the leadership skills needed to cope. You and I would probably not done much better.
Sorry, Katrina is in a whole other order of magnitude from 9/11. We're talking a few buildings knocked down vs. widespread destruction across an entire city and ensuing unlivability and anarchy.
Also, with 9/11, federal aid was instantaneous.
9/11 was a tragedy, but it has been so played-up to incite "patriotism" that many have lost perspective on what a true disaster is.
Blue Sky, Whole Foods 365 Brand, and many other sodas sold at "natural" food stores use real cane sugar as well, and they're quite good. Can't buy them from a vending machine in the office though.
Will you stop arguing against things I haven't said? I never mentioned Kyoto (and your claim that it would "cripple the ability of first world nations to produce any kind of goods" is more doom-and-gloom than anything I have said).
Did you know that there's evidence the Rockies (in general) have risen three feet just in the last century? The Himalayas are even more active, as the Indian subcontinent is slamming into the side of Asia.
What evidence? Point me to a study. I AM a geologist, and I AM familiar with the current literature on Rockies tectonics, and 3 feet in a century is a ridiculously high rate of surface uplift. We could MEASURE that with instrumentation.
The Himalayas ARE very active, but are eroding as fast as rock is being delivered to them. The major climate influence is not the mountains themselves but the extensive, high Tibetan Plateau, which has been about at its current elevation since 8 million years ago.
And if you choose to ignore the geologic effects, then clearly errosive effects are in your time frame. Forest fires clear more land and produce more CO2 in one burst then most man-made effects do in a year. Mount St. Helens has created more pollution this year than the entire state of Washington. Rivers cut new basins, and hills are worn down.
I discussed the effects of human-induced burning on atmospheric CO2 (and methane...). Volcanic eruptions happen every year and ARE a major source of these gases in the atmosphere, in fact they are the ORIGINAL source. That doesn't mean HUMANS don't have a significant impact. Rates of river incision and hilltop erosion, except in extreme cases, don't exceed a few tens of meters per MILLION years (and because of isostasy, ~7/11 of the elevation lost this way is regained).
Methane is 21 times as powerful a GHG as CO2, but no one talks about that, because it's predominantly formed by wetlands. You want to reduce global warming? Let's drain all those damn wetlands. And get rid of hydro-electric power, because every dam in the world produces three times the GHG as an equivalent coal plant because of the release of huge clouds of methane from their drowned resevoirs.
I DID talk about methane. Methane formed in wetlands is NOT easily transferred to the atmosphere, because it forms in the mud, reacts with oxygen in the water column and turns into CO2 and water before it gets into the atmosphere. It's only transferred to the atmosphere as methane in special cases, such as rice paddies, where the hollow stems of the rice provide a direct path to the air. It's also produced by ruminants and biomass burning (forest fires, natural or otherwise).

HeH yOUz FAILeZ IT!
HA-Ha!
No.
In the back seat you were at risk of contracting any number of things, but not a rootkit.
... to erase it.
...you want a rootkit in your whiskey...
Seriously though...this patent seems very valid.
It does? Have you read it? What's the patent #? Or are you just trolling?
It's ALL dark.

You must be new here.
One of the great advantages of the blogosphere is that this sort of stuff gets found out very quickly.
And one of the great disadvantages to the blogosphere is that it's called the blogosphere.
mmm... Shorts...

Is that not one of the most ironic things you've ever heard?
No.
Completely different. Completely. And if you could help yourself, why didn't you?
But, if you take it literally as written, how do you resolve the conflicts between various passages without some amount of interpretation?

Oooh, a whole WEEK ago! You MUST be cool reading ALL these sites EVERY minute, just WAITING for that FRESH scrap of news!
There is an Outside. BELIEVE in the Outside.

Endor.
It comes in pints!?
