<UmbralRaptor> Dear Patriots,
<UmbralRaptor> Today, Monday April 29, 2019, Mason Police and other regional public safety partners will be conducting active threat training at EagleBank Arena. Due to this training you may see an elevated law enforcement presence in the area of the arena as well as officers in tactical gear. However, there is no threat to the public.
<UmbralRaptor> Com's of living in the DC area: it's still 2002

<UmbralRaptor> Apparently someone at ETHZ is studying the rheology of Phobos and Deimos
<UmbralRaptor> And Phobos could plausibly be captured, but deimos not so much?
<egg|laptop|egg_> UmbralRaptor: the rheology? O_o
<UmbralRaptor> Yes.
<UmbralRaptor> Unfortunately, petting the moons is impractical. Consider asking JAXA about joining their MMX mission?
<egg|laptop|egg_> UmbralRaptor: I don't understand what rheology has to do with the moons
<UmbralRaptor> uh
<UmbralRaptor> Well, when a planet pets a moon hard enough, the moon deforms in response. Legendre polynomials came up.
* UmbralRaptor was reminded of Jackson =\

<SnoopJeDi> oh right, I forgot to finish rebooting galois

<egg|laptop|egg_> well
<egg|laptop|egg_> AltiKa
<egg|laptop|egg_> ALtika
<egg|laptop|egg_> gah
<SnoopJeDi> oh lol the VPS is full
<egg|laptop|egg_> whitequark: I'm getting a 504 on https://esper.irclog.whitequark.org/kspacademia/

<SnoopJeDi> thanks for the ping UmbralRaptor
<egg|laptop|egg_> !acr -add:SARAL Satellite with ARgos and ALtika
<galois> Definition added!
<UmbralRaptor> I guess
<SnoopJeDi> Apparently the VPS filled up (it's cheap), that crashed Sopel (lol) but it didn't clean up in the process of crashing, and if a .pid file exists for a bot's config but the process is gone, the initializer throws a confusing message.
<SnoopJeDi> actually, I guess I could write a patch for this, since it's Python.

<egg|laptop|egg_> B787_300: WOW there is quite a bit of difference between the maximum latitude and the osculating inclination at the node
<B787_300> how much
<egg|laptop|egg_> for 10 days of SPOT-5 I get i = +98.72941(26)° at ☊ but i = +99.9014(34)° (from ψ_m)
<egg|laptop|egg_> more than a degree
<egg|laptop|egg_> (the value at ☊ is the one that's generally quoted as the inclination)
<egg|laptop|egg_> milder on other orbits
<B787_300> i assume i just gets worse or does it oscilalte?
<egg|laptop|egg_> not sure, will dump the range
<egg|laptop|egg_> the uncertainty is low so it can't oscillate *that much*
<egg|laptop|egg_> well
<egg|laptop|egg_> oscillate that much between orbits
<egg|laptop|egg_> it's probably the result of a 1-orbit oscillation of the osculating inclination ofc
<egg|laptop|egg_> B787_300: oh, the max latitudes cover a much broader range than the inclinations at AN
<egg|laptop|egg_> B787_300: from 98.5 to 101.5
<B787_300> and correct is 99.9?
<egg|laptop|egg_> mean of that is 99.9, what do you mean by correct
<B787_300> from ψ_m
<egg|laptop|egg_> whereas the inclinations at AN range from 98.727 to 98.732
<egg|laptop|egg_> yeah that's the mean of the ψ_m, where ψ_m is the max latitude on an orbit
<egg|laptop|egg_> weird how much the inclinations at AN vary
<egg|laptop|egg_> s/AN/max latitude/
<galois> egg|laptop|egg_ meant to say: weird how much the inclinations at max latitude vary
<B787_300> yeah dont know what to say
<egg|laptop|egg_> (I could have screwed up my search for maximum latitude of course)
<egg|laptop|egg_> maybe that's the answer
<egg|laptop|egg_> this is too weird to be true
<kmath> <jgerity> oh my god this stupidity has mutated so much in the last 9 hours ⏎ ⏎ I had nO IDEA that using plain language to talk a… https://t.co/Ssnr1o0mHr
<UmbralRaptor> (also, I'd like to assume that freshman physics always uses a right handed coordinate system o_O)
* UmbralRaptor glares at electrons
<Ellied> mofh: we found some other markings on the building we actually entered that look older than what we saw on the main streetside
<Ellied> "Roton Assembly"
<egg|laptop|egg_> UmbralRaptor: also tends to give you bases, and if you have a basis you have an orientation and more
* UmbralRaptor was going to guess something about Kistler, but they were apparently based in CO
<egg|laptop|egg_> (well, an ordered basis)
<egg|laptop|egg_> (if you want to argue that your basis is unordered, sure)
<egg|laptop|egg_> Ellied: did a P fall off
<UmbralRaptor> Протон!
<egg|laptop|egg_> alternatively, assembling p⁺
<UmbralRaptor> Anyway, speaking of coordinate system madness, several of this week's GR homework problems seem to be arbitrary symbol pushing
<egg|laptop|egg_> ah right i should keep telling you about linalg
<egg|laptop|egg_> i'll try to do that tomorrow
<egg|laptop|egg_> unless mofh beats me to it of course
