egg|zzz|egg meant to say: ferram4: how would those wing shapes do at the cruise speeds of the corresponding aircraft? https://xkcd.com/1824/
<ferram4>
Probably better than ours currently do, due to the advantage of them being extremely variable wing shapes.
<ferram4>
Except for the Hornet, those will be shredded.
<ferram4>
I suppose it's questionable for the Blackbird considering its high cruise speed, but for everything else, cruise speed is subsonic, so sweeping the wings back a little bit is all that would really be needed.
<ferram4>
egg|zzz|egg, ^
<egg|zzz|egg>
hmm, interesting
<ferram4>
Really, the reason I can say this is because they're bird wings (so flexible) and you said cruise speed (which is subsonic for all except the blackbird)
<ferram4>
They would likely not play well with higher transonic or supersonic speeds.
<ferram4>
Probably destroyed by flutter or heating.
<egg|zzz|egg>
yeah, the hornet is questionable >_>
<egg|zzz|egg>
ferram4: what if you made them that shape (or similarly variable-shape), but out of non-birdlike materials
<ferram4>
Depends on the stiffness of the joints.
<ferram4>
They'll be less lift / drag efficient than our designs, likely.
<ferram4>
The main issue is if they will be stiff enough to hold together.
<ferram4>
Now, at low speeds they'll be far better at producing lift than the real life versions.
<ferram4>
Also very good at producing drag for landing.
<ferram4>
egg|zzz|egg, oh, also, the non-birdlike materials birdlike wings will unfortunately be extremely heavy.
<egg|zzz|egg>
ah right

nice, I get "virtual computer lab access" through IIT, to "a Windows desktop and important applications for coursework" according to the description. If I click "create reservation" though, I get two options: 1) "IIT Linux (No Applications)"; 2) "IIT Linux (With Open Office)"

University IT is applied lying
<UmbralRaptor>
The correct approach is probably to do everything except printing on hadware/software you control. And I suppose use their bandwidth if need-be.
<SnoopJeDi>
If you're allowed, yep

Hopefully you don't actually need Windows?

whitequark: also they made a short video of similar funny orbits in the Kerbin-Mun system; note that it looks square in both the Kerbin-centred and the Mun-centred reference frame, not just a "wrong frame" kind of thing :D https://www.youtube.com/watch?v=9Aq8nYL03Ts

hmm no, that one in particular looks elliptical in the KCI and KMB frames actually
<egg|zzz|egg>
(though elliptical *centred on a body* rather than with a focus at a body, so still quite weird :D)

<SnoopJeDi>
Had grad student harassment with yesterday's colloquium speaker this afternoon, and she's got a few of us all atwitter thinking about her concept for using ssDNA to detect WIMPs https://arxiv.org/abs/1206.6809
<soundnfury>
SnoopJeDi: crikey, that's cunning
<SnoopJeDi>
right?! she said over coffee that the "old carbon" strands are basically sitting in a freezer waiting for an enterprising-enough experimentalist to have a go at it
<SnoopJeDi>
and I confess that the call for "we need experimental data for how ssNA breaks at the ~ eV scale" is stirring thoughts of an inner experimentalist long since dead
<SnoopJeDi>
oh I should also mention her discussion of a "dark star" concept, where DM annihilation drives everything energetically instead of fusion: https://arxiv.org/abs/1501.02394
<SnoopJeDi>
Really compelling suggestion for the origin of the large population of supermassive black holes
<SnoopJeDi>
And apparently quite detectable by JWST!
<whitequark>
SnoopJeDi: whaaaat
<SnoopJeDi>

We report a population of AGN powered by the "Take That, Eddington!" mechanism.
<soundnfury>
UmbralRaptor: observations of Weakly Transient Foci to cover the Observational Measurement Gap indicate that Laser Obstructed Lensing may yield an improved Boltzman Band-gap Quotient compared to existing experimental methods.
<soundnfury>
This work was supported by the Ridiculous Or Farcical Laboratory and Mainly Acronymic Observatory.
<UmbralRaptor>
soundnfury: You will be submitting this to the snarxiv, yes?
<UmbralRaptor>
SnoopJeDi: belatedly, that ssDNA to detect WIMPs seems cool, feels like it's solving the wrong problem?
<UmbralRaptor>
(If WIMPS exist, can they stand out above the cosmic neutrino background?)
