Hello,
Interesting stuff in last week's Nature
http://www.nature.com/nature/journal/v449/n7158/abs/nature06070.html
But what I really, really loved was, elsewhere in the magazine, that
sentence....
"The various surveys that were set in motion in the 1990s have reduced
by almost an order of magnitude the risk of collision with a previously
undiscovered asteroid that could drastically affect the global
environment."

I presume the writer was assuming the reader would know that the risk
he was referring to was the known upper limit to the risk, and not the
actual risk, whose value wouldn't be changed unless we started moving
asteroids around.
Actually, though, the sentence could be literally true. Our risk of
being hit by just *any* asteroid may still be the same, but now, nine-
tenths of the asteroids that could hit us, and which are big enough to
"drastically affect the global environment" may no longer be in the
"previously undiscovered" category.

Heh! Last week's issue was especially good. It also has "The Riddle
of Inertia" -- how Earth's rotation reshapes space and time". That
issue,
or the previous week's, also featured how the area east of Denver
validates the K/T extinction. Fascinating magazine, just wish it
didn't
cost so much. :-)

Yes, that was that issue. Here as well.

Looks like an amazing site.

That's what I told myself for years before finally taking the plunge. It
isn't that expensive, given the fact they have weekly issues for most of
the year. A two year subscription boils down to approx $3.40 per issue.
I've seen more expensive junk ;-)
