the thing about the "inverse" of cosines of multiple angles,
was cool; does it work with sines, trivially?

"Time is not a dimension; or, it's the only dimension,
whereby we preciece any others," Bucky saith, compared
to Minkowski's ridiculous slogan about a mere phase-space
(then, he died).

thus&so:
are they still using the passive albedo & evapotranspiration,
ignoring the burning of "fossilized fuels" and nuclear power?
there is a longstanding anomaly, not described by any model =
or GCM, that the nights & winters are warmer =
than the days & summers; so, do the math!

thus&so:
arctic ice isn't stable; it's all floating, won't change sea-level
if it should melt. (we must take into acount *all* human actions,
where possible, not just mere emmssions from Al Gore's footprints .-)
here's another thing that I've never seen considered about it,
when I read of Buzz Aldrin and company's picnic at the N.Pole:
750K-horsepower Soviet ice-breaker to get there. now,
get the schedule for that turkey & do the math of angular momentum!

thus&so:
the elephant in the water is Waxman's '91 bill on SO2 and NOX,
which supposedly was very effective, and it is cap&trade. so,
why does the Wall St. J. call his current bill, that's passed,
"cap&tax" -- did they refer to Kyoto as cap&tax, also, then?
while sequestration probably will not work,
there is one way of making fuel out of CO2 from coalplants,
combining it with methane to make methyl alcohol,
developed by a Nobelist, and used commercially for busses
in Europe and Asia, already, along with a further transformation
into another fuel.

thus&so:
Waxman's '91 bill on NOX and SO2 was cap&trade ...
Kyoto was cap&trade & Dubya "ought" to have signed it,
by his lights as an MBA ...
Kerry-Lieberman's and Waxman's passed bill are nothing,
but "freer trade," cap&trade.
so, why can't we just have a simple, small carbon tax,
thatt'd be a lot like a VAT, it's so all-encompassing --
which Waxman doesn't seem to realize, and is certainly
being played-down by the "yeah" and "neigh" sides
of this political debate; eh?

thus&so:
Oilgate is, Californians be #1 consumers of Gulf and Alaskan,
with Beyond Phossilized Phuels the largest producer --
I think, unless Shell is, in Alaska (but, it's half British).
sure, partly because we have the biggest population but,
another example of British perfidy (*prefide Albion*), that
Climategate could have purposely been leaked, because
the "mainstream" is so hegemonic with their rough-hewn GCMs,
which simply cannot predict weather with much fidelity,
for any length of time & given approximation
to "initializing-the-model conditions."
the funding for the old "cooling" paradigm
of the last two million years (Quaternary preiod),
went out the door to "warming," with a mid-'70s meeting
of the NSF, at which Oliver "Buck" Revelle laid-out the matter
-- he, later to be an unindicted co-conspirator
of George HW Bush in Iran-contra! (of course,
HW was also not indicted, just like for Watergate;
see http://tarpley.net).

thus&so: took just one of your exempli gratia; dyscuss!

thus&so:
so, you believe in the corpuscle, discredited by Young (well,
it was never a theory *per se*, from mister Fig "hypothesis non
fingo"
Knewtonne; that is, he asserted that light goes faster
in denser media, which was already (I believe) out of whack
with Snell's law of refraction, proven by Fermat).
of course, the most important milestone, aside
from Roemer's proof of the non-instanteity of light
(waves, he didn't know), was the elucidation of the "path
of least-time" by Leibniz and Bernoulli -- although,
that is just "ray-tracing," which is often interpreted
to be the path of a rock o'light!

--my broker says to call your broker about cap&trade, and
I'll tell you what happens.

Thank you. I thought there might be a category where every element in
the adjoint contained a factor of the determinant. Now I see that's
impossible, because then the determinant would become proportionately
larger, so you'd have to make the adjoint larger, and then the
determnant would become larger ... ad infinitum.
