Binomial's Theorem ROFL
<bofh>
anyway I've been reading these notes and honestly this is a course I'd love to *teach* someday, it's magnificent
<egg|zzz|egg>
bofh: so sadly I don't think I have the prof-provided notes in electronic form
<bofh>
Oh of course it's Trubowitz
<egg|zzz|egg>
oh you know about Trubowitz? :D
<egg|zzz|egg>
bofh: I have printouts of things tho
<bofh>
YEP :D
<bofh>
also rofl at Lemma ("Your life in Fourier land depends on it.")
<bofh>
I am so stealing that
<egg|zzz|egg>
paving the way for new generations of trubowitzes I see :-p
<egg|zzz|egg>
bofh: his last course here was about the БКЛ conjectures
<egg|zzz|egg>
specifically, proving them for homogeneous spacetimes
<egg|zzz|egg>
bofh: also about bashing penrose at every turn
<bofh>
yes, Penrose co-authored a book with Deepak Chopra. yes, *that* Deepak Chopra. yes, it is atrociously horrible.

"They adroitly sidestep the problem of defining what a singularity acturally is, by saying it is the 'place' where their light rays end. The proofs of incompleteness theorems are not hard. That's good. Unfortunately, they are by their very nature completely non constructive and provide no quantitative information at all about what a 'singularity' really looks like."

whenever i think of the final anthropic principle i think of Timelike Infinity
<Fiora>
which has a cult that has theorized that the final observer, at time infinity, has the ability to choose the ultimate path of all of history by choosing how the wavefuntion collapses
<UmbralRaptor>
Yay, Xeelee.
<Fiora>
(see, quantum woo DOES make for good fiction.....)
<egg|zzz|egg>
would it be worth dropping contextuality by switching to Bohm's interpretation to get rid of that crap >_>
<egg|zzz|egg>
(uh, noncontextuality that is)
<bofh>
Fiora: hey that does sound like an actual interesting fiction idea
<Fiora>
baxter novels are basically Hey, What If I Wrote A Novel Based On This Entire Stack Of Interesting Physics Fiction Ideas
<Fiora>
there's also one where an entire civilization lives inside a neutron star crust.
<bofh>
oh man the Baxter/Clarke novels I read were pretty interesting
<bofh>
but yeah, I think Baxter is one of my fav SF authors
<bofh>
and then there's Greg Egan, which is in a class all of their own.
<bofh>
egg|zzz|egg: you should read Egan's Luminous, it's a short SF story around mathematics
<egg|zzz|egg>
@$%@#$ where did I put the БКЛ lecture notes
<bofh>
man I'm rereading Luminous right now and holy shit I forgot how much I liked it

<elakdawalla> Niebur: "Enceladus has no business existing. It is screaming ... 'I completely invalidate all your assumptions about the solar system.'"
<bofh>
that's a fairly high inclination.
<bofh>
UmbralRaptor: <shrug> there's cryovolcanism on Triton, I honestly don't think volcanic activity on moons is at all unusual.
<bofh>
Enceladus just happens to be really picturesque b/c it's mostly ice.
<SnoopJeDi>
bofh, I really really really like the way they cut the approach to the planets in The Farthest
<SnoopJeDi>
as well as the way they cut/shot most other things; I think it's the best-produced PBS doc I've ever watched
<bofh>
SnoopJeDi: agreed
<SnoopJeDi>
the music ;_;

the music was phenomenal and the best part IMO

like there are strong shear winds resulting from all the dry air dumped in the gulf that are preventing rapid intensification, but...
<SnoopJeDi>
I snuck out to grab some Subway and the sky to the southeast was pretty icky looking. Poor Houston :(
<bofh>
the joke tweet about Harvey turning into a permanent fixture in the gulf along the lines of a terrestrial GRS suddenly seems not 100% implausible.
<SnoopJeDi>

I just finished the 3rd book in NOAA/NSF's summer library series, Kim Stanley-Robinson's "Forty Signs of Rain," and the serendipity of it is eerie
<SnoopJeDi>
the driving climate event in the book is an ice shelf breakoff (like what we saw last month) that stalls the North Atlantic current and spawns a massive flood event in DC

the discussion is...gonna be unsettling.
<bofh>
oh gods that is disturbingly not outside the realms of plausibility
<SnoopJeDi>
Yea his premise is alarmingly well-posed
<bofh>
SnoopJeDi: so the various posts to the effect of the highway system is designed to carry away excess rainfall in the event of exactly that are more-or-less correct, yeah?
