<Ellied> RIP Cape Coral (in the eye now). Sarasota is next, the Tampa.
<Ellied> it's veering a little more east than they projected earlier today; looks like the eye wall is going to be mostly over land.
<Ellied> one of my physics classmates asked me the infamous "can we nuke the hurricane" question the other day. :u
<UmbralRaptor> Floridians are strongly discouraged from firing their casaba howitzers at the hurricane.
<Iskierka> I don't remember whether the answer to that is "it doesn't do shit" or "it makes it angrier"
<Iskierka> but I know it's one of those
<bofh> iirc, the former
<egg> well there's also the question of fallout right?

<bofh> UmbralRaptor: wow, that's insanely late. also damn.
<bofh> 2005 also featured Katrina, iirc.
<bofh> "of the apparently never-ending"
<UmbralRaptor> Yep.
<Ellied> Iskierka: AIUI, hurricanes contain many orders of magnitude more energy than even our largest nukes. You'd just end up with a mildly radioactive hurricane (or very radioactive, if you for some reason did a surface burst)
<Iskierka> obvious follow-up: what if you did make one big enough though
<Iskierka> (or nuked them early)
<UmbralRaptor> I'd be worried that the thermal results would, uh, be unfavorable.
<UmbralRaptor> >_>

<kmath> <CostaSamaras> Wonk twist: if you paid for 60kWh but they put in an extra 15kWh you could unlock, means you've been lugging extra… https://t.co/VoyEHAzhly
<Iskierka> *that* argument has a point, but you are paying for the curb weight quoted
<Fiora> to be fair, you bought a tesla, every day it continues functioning is a minor miracle
<Iskierka> and another side is that if you bought 60 kWh they're probably taking it largely from the side that keeps it away from 4.2V so lifespan is increased
<Iskierka> there could probably be another option for an emergency mode that would push it up towards that with a warning to use the charge soon for even more range
<Fiora> yeah when i first read about the "upgrade" (re hurricane) i assumed they were optionally adding the ability to break the safety limiters
<Fiora> i.e. allow users to get another 30 miles at the cost of significantly damaging battery
<Iskierka> Doing that would definitely be doing something big to help
<Iskierka> Eh, one overcharge used reasonably soon (within 12-24 hours) isn't significant damage
<Iskierka> just don't repeat it
<Fiora> that's what i mean
<Fiora> significant *compared to normal use*
<Fiora> but if only done once for good reasons, probably okay
<Fiora> isn't it also a matter of over*draining* too?
<Iskierka> tbf it's not even that much damage if you do overcharge regularly, so long as it's used quickly. Just noticeable compared to baseline. The real damage is leaving it charged there
<Iskierka> overdraining doesn't seem to be a problem in my experience, but actively draining with a use vs. just letting the voltage decay over time might be the difference
<Iskierka> I've seen lithium cells with the latter recovered from like 2.5V with basically original performance
<kmath> <whitequark> #catcognition cat stared at me like "i want something". i followed her. she led me to front door. sure. I put the collar on her & open door.
<Iskierka> phones won't risk charging cells that low because super low voltage *could* also be damage, but I recovered an old phone using a charger intended for RC batteries which didn't care; you're supposed to watch the battery charging, not their fault if it explodes

<Fiora> unexpected side effects of ephedrine experiment: i'm sleeping at least 1h less per day
<Fiora> i don't feel any less need to go to sleep but i'm sleeping less overall
<Iskierka> yay for random drug experiments?
<Fiora> it's not really random! i really like norepinephrine
<bofh> Fiora: interesting. that matches somewhat well with my limited pure-NRI experiences, in that I would sleep a "normal" (5-6hrs) on just 48mg ephedrine/day instead of nothing but couldn't chain multiple allnighters like I could on 40mg dexedrine
<Fiora> yeah i'm doing about 48 a day
<Fiora> and now i do okay with 5 hours of sleep + 1.5 hour nap
<Fiora> instead of 8 hours of sleep + 2.5 hour nap
<bofh> granted, that was complicated by it being post stimulant crash due to pharmacy fuckup, so it was more substitution of an NDRI with an NRI.
<bofh> yeah, that's not unexpected but sounds very handy honestly
<Fiora> which NDRI?
<bofh> well, technically releasing agent, but I think so's ephedrine. in my case d-amphetamine, this was like 5 years ago.
<Fiora> ahhh okay
<Fiora> is ephedrine a release agent or something that directly binds to the receptors?
<Fiora> i thought it was the latter
<Fiora> i'm still kinda wondering what makes e.g. d-amphetamine so different from sibutramine even though they're both NDRIs
<bofh> it's complicated. it both binds to the transporter (tho I can't recall if it does efflux or just inhibits uptake, heck I'm not sure about amphetamine even, that might even be a DRA/NRI according to one paper) and to I think alpha receptors?
<Fiora> I think amp is both DRA and DRI and NRI?
<bofh> I think it's partly sibutramine has much more affinity for SERT and less affinity for DAT, but the full answer iirc is we don't know.
<bofh> Yeah, that sounds about right.
<bofh> Granted, DRIs are fucking weird since the dopamine transporter makes no bloody sense.
<bofh> In theory, when you occupy 100% of transporter sites, taking more of a DRI shouldn't do anything since all it does is inhibit uptake.
<bofh> And like, we see exactly this for SSRIs and SERT, there's a clear ceiling at which a SSRI alone won't do anything.
<bofh> for DRIs? lolnope, MPH somehow modulates firing rates of mesolimbic dopamine neurons even at nearest we can tell 100% DAT occupancy.
<bofh> (it's been awhile, trying to dig up that paper right now)
<bofh> "We describe the experimental findings which suggest cocaine serves as a negative allosteric modulator to alter the function of the dopamine reuptake transporter (DAT) and reverse its direction of transport. This results in a firing-dependent, retro-transport of dopamine into the synaptic cleft. The proposed mechanism of cocaine is, therefore, different from other small molecule negative allostereric
<bofh> modulators of the monoamine reuptake ...
<bofh> ... transporters, eg SoRI-6238, which merely reduce the rate of inward transport. Because the physiological role of DAT is to remove dopamine from the synapse and the action of cocaine is the opposite of this, we have postulated that cocaine's effect is analogous to an inverse agonist."
<bofh> whitequark: ^
<bofh> but that would make sense, if MPH (which that paper also says does the same) also induces retrograde transport, that would explain the lack of a dose-ceiling effect.
<Fiora> that's whacky
<bofh> brains generally are. tbh I still think my favourite is "a subset of dopamine D1 receptors covalently binds to a part of the NMDA ion channel complex with its transmembrane-spanning tail and directly gates the ion channel upon dopamine binding". Lime you can't even call it a GPCR at that point, no G proteins are involved.
<bofh> it's like this bastard mess of a ligand-gated ion channel / ligand-gated 7TM receptor heteromer.
<bofh> cool, X8.28 flare
<Fiora> nice
<Fiora> will we be seeing auroras
<bofh> can sunspot AR2673 give it a rest?
<bofh> not too likely this time, it's located on the edge of the sun facing us & so I think the CME will mostly miss?
<bofh> it did essentially make all the ham bands unusable today until nightfall
<bofh> ofc I could be wrong, but tbh I'd love to see auroras again
<bofh> they're so pretty
<Fiora> i dont think i'e ever seen one
<SnoopJeDi> I haven't but it'd be a real treat
<bofh> I saw a faint one from the X9.3 flare a few days ago. O(¹S) 557.7nm green pretty much exclusively, which is what I'd expect this far south.
<bofh> before that the last one I saw was an even fainter one but that one had some O2(³P->¹D) 630nm too
<bofh> in 2010
<bofh> and that's it. still really want to see proper aurorae above, like, the arctic circle someday
<bofh> (yeah most auroral emission is from oxygen)
<bofh> tbh highly recommend if you ever get the chance.

<UmbralRaptor> Also, ? ACS apparently.
* UmbralRaptor wonders if Michael Eisen ever got hassled for posting that report by Obama.
<bofh> I think even O2(A³Σu+) can occur in the far upper atmosphere, tho I'm not sure (that's ~240 - ~260nm)
<bofh> don't ask why I have atomic transition lines of both neutral and radical oxygen memorized b/c I actually have no idea why.
<bofh> tho I think the ³P->¹D line is actually for the radical as well on second thought (should check NIST spectral db)
<kmath> <TubeTimeUS> this is a Stirling Spiral light bulb from 1900. i think it's the oldest thing i own. https://t.co/pFttyl978b
<bofh> yep it's for O I, not the neutral form.
* UmbralRaptor sometimes recalls OIII having a line at 5007 Å, and that there are other OII and OIII lines scattered in the green to near UV range. >_>
<UmbralRaptor> Extra fun: I'm using a terminology where OI is neutral.
<bofh> so O I & O III both have tons of greenish lines
<bofh> erm, OII*
<UmbralRaptor> ah
<bofh> like there's a 543nm & a 595nm one off the top of my head
<bofh> just those are iirc O(5P) & O(³P->³D) respectively
<bofh> for low-energy ionization the O(¹S) line is going to dominate emissions

<egg|zzz|egg> bofh: so this isn't homework, it's lecture notes, but still it's a good example http://i.imgur.com/jb6pVxJ.jpg
<bofh> so I can read that but there is slight difficulty, and mine's comparatively bad.
<egg|zzz|egg> bofh: it's funny to see which sequences of letters are detached and which are written without raising the pen in that mess
<egg|zzz|egg> the dot of the i tends to get ligatured to whatever follows
<egg|zzz|egg> similarly with the bar of the t
<bofh> so like the t bar is *supposed* to be ligatured I think? at least in I-can't-believe-it's-not-cursive
<egg|zzz|egg> bofh: uh, with the following letter? I don't think so no
<egg|zzz|egg> unless you're doing fancy stuff with tz or whatever but then you're not writing cursive, you're writing street signs in Berlin
<soundnfury> egg|zzz|egg: wow, your handwriting's a lot worse than mine. To the point where I've recalibrated my notion of what counts as bad.
<egg|zzz|egg> soundnfury: it's just full of ligatures that change the shape of everything, like in arabic :D
<soundnfury> how do you manage to turn an en into an en dash?
<egg|zzz|egg> the "int" in "pointwise" at the bottom also has an n that vanishes, or maybe turns into a ν
<soundnfury> e.g. "co-taini-g"

<egg|zzz|egg> (dot of the i -> n -> ascender of the t being one stroke)
<egg|zzz|egg> poiνtwise
<soundnfury> looks like peirtuise to me
<soundnfury> (is that a colour?)
<egg|zzz|egg> well it's fairly clear how the n degenerates by looking at the word containing, that second n still vaguely bulges up, and the other ones have been fully extended into -
<egg|zzz|egg> note that the r can do the same, look at the word pair that follows
<egg|zzz|egg> bofh: also note, these are the notes for Sudakov's (extremely good) course on the algebraic method in combinatorics, hence the lack of articles :-p

<bofh> I have a tendency to do the same, for instance my Statmech/Intro to Gauge Theories notes are like that
<egg|zzz|egg> bofh: afaict it's not taught from a text other than Sudakov's notes
<egg|zzz|egg> bofh: that course had *a lot* of post-2000 dates in it, fairly cutting-edge
<kmath> <elakdawalla> Later on, same scientist asked me to review a paper of his and "perform algorithm that randomly insert 'a', 'an', and 'the' into text"
<bofh> egg|zzz|egg: so like when I say 'text' I include 'notes from the professor' since that's been the case for nontrivially many of my courses :P
<bofh> LOL
<kmath> <elakdawalla> (It's funny, some of you don't know what I'm talking about but anyone who's reviewed English text written by a Russian understands.)
<bofh> YEP
<bofh> worst part is I'm somewhat used to reading that sort of accented English, so unless I force myself to notice it still sounds natural enough that I overlook the missing articles.

<SnoopJeDi> bofh, I told you about the Russian phrase I learned at that beam cooling conference, right? "не невозможен но очень трудна"
<SnoopJeDi> which is knee-slapping hilarious in the context of "we just spent 90 minutes listening to people talk about muon cooling schemes"

<soundnfury> reminds me of my motto. "the impossible we do immediately. The difficult takes a little longer"
<bofh> Accurate.
<SnoopJeDi> I believe the guy who taught it to me was pretty close to the original cooling experiments in Russia, so I found it pretty apropos. Nice guy, although I guess I get the benefit of him knowing my advisor from those days.

<SnoopJeDi> our resident happy hour tyrant submitted it for the weekly drink bounty (a link we include in the email -> a free drink on me or the other organizer)
<SnoopJeDi> Real shame how hard it is to encourage people to share articles as such, even if a boozeprize is offered. People largely haven't even bothered so he's generally uncontested.
<Iskierka> the smallest uninteresting number as of nov 2016 is a mcnugget number

<bofh> SnoopJeDi: dang, that's honestly depressing. tho I've had similar experiences here :(
<SnoopJeDi> The new grads seem more interested in participating so that's been a shot in the arm, but yea :(
<bofh> well, hope they continue. we had a lot of enthusiasm initially last year but a lot of it did falter, otoh now there's at least 3 people consistently suggesting papers instead of two so that's good.
<SnoopJeDi> We don't even require them to be papers, anything sufficiently novel is definitely up for grabs. I honestly *prefer* digest articles by good outlets that link to a paper.

<egg|zzz|egg> bofh: hmm, https://www.youtube.com/watch?v=WS5UxLHbUKc I wonder whether there's a way to do this sufficiently generally that it can be applied automatically (e.g. to retrobop chaos or whatnot :D)
<kmath> YouTube - TRAPPIST Sounds : TRAPPIST-1 Planetary System Translated Directly Into Music
<bofh> egg|zzz|egg: so like the description goes into the method involved, it's planetary occultations that feed into the envelope generator and orbital frequencies shifted up to audible range that feed into the waveform generator
<bofh> so yes this is 100% feasible to any algorithmic planetary system simulation.
Technicalfool_ has joined #kspacademia
<egg|zzz|egg> bofh: but how do you define the orbital frequency properly
<Iskierka> the further question would be can you hear the difference between an unstable and mostly-stable system
TechnicallySleeping has quit [Ping timeout: 204 seconds]
<bofh> egg|zzz|egg: um 1/(orbital period)? :P where orbital period is the obvious Keplerian one
<bofh> obviously this gets complicated in the case of any sort of chaotic orbit
<egg|zzz|egg> bofh: the obvious (osculating) Keplerian one is going to be noisy as hell tho
<bofh> Why? It's just going to be a frequency-modulated sine.
<bofh> that's not noisy, that's a Yamaha OPLL :P
<egg|zzz|egg> hmm
<egg|zzz|egg> I wonder what would happen if I just did the "orbital frequencies shifted up to audible range that feed into the waveform generator" part with the orbit of retrobop
<egg|zzz|egg> do I even have the data for that though
<egg|zzz|egg> probably not
<bofh> just re-run a retrobop simulation? :P

<bofh> UmbralRaptor: disturbingly relatable
<egg|zzz|egg> bofh: my msc thesis is firmly in enumerative (eggstremal) combinatorics, so I guess I should have an idea
<egg|zzz|egg> bofh: but tbh I don't
<egg|zzz|egg> so we're looking for functions from [2^n]^2 to [2^n] that are associative... I feel like this should be amenable to the algebraic method is some perverted way (if only because it all starts with algebra :-p)
<egg|zzz|egg> meh maybe not
<bofh> yeah I'm unconvinced.
