<SnoopJeDi> ...huh. I've just gotten back from a colloquium with a LOT of really convincing and encouraging things to say about ITER/fusion at large.
<SnoopJeDi> and a lot of really fun geometrical arguments about things like turbulence in the blanket-plasma boundary layer and how that constrains tenable systems
<SnoopJeDi> (spoiler alert: yes, fluid dynamics is still really really hard but at least you can kinda brute-force it now if you've got $∞ to burn")

<egg|anbo|egg> bofh: meh the weather is shit, not sure

<bofh> fog, slight rain and a temperature strictly > 0degC
<bofh> meh :P
<egg|laptop|egg> bofh: well, walking 5 km in the rain does not sound fun
<bofh> egg|laptop|egg: yes but it beats walking 5km in windchills of -33degC
<bofh> which I *almost* did but NOPEd out of
<egg|laptop|egg> my swedish colleague is eggstremely weirded out by americans always reporting windchill-corrected temperatures
<SnoopJeDi> "corrected"
<bofh> why's that? when it's below 0degC and your wind is, like, 30km/h with gusts to 50km/h *or worse*, that's very significant
<bofh> does sweden not, like, get wind or something?
<SnoopJeDi> it makes more sense to me to report those two quantities as...two quantities
<egg|laptop|egg> bofh: it gets wind, but what SnoopJeDi says
<SnoopJeDi> with the possible admission of those two + "feels like," which I find acceptable if not extremely imprecise
<egg|laptop|egg> they just know that it's cold, and that there's wind
<SnoopJeDi> I have the luxury of a fairly poorly insulated apartment
<bofh> SnoopJeDi: I mean for meteorological purposes, agreed, but for purposes of going outside, most people have a bad mental mapping I find.
<SnoopJeDi> so I just gauge the day based on how it feels when I wake up :P
<SnoopJeDi> bofh, yea the interface between "we are professional weather people" and "do I need a jacket today?" sucks badly
<egg|laptop|egg> bofh: apparently swedes are pretty good at having a feeling for that
<egg|laptop|egg> bofh: maybe because swedish weather
<bofh> like I do prefer getting both, since like -30degC with <5km/h winds is pleasant and -5degC with ~35km/h winds is "yeah, I'm not stepping outside, fuck that".
<SnoopJeDi> oh, y'all might appreciate this mildly interesting heat problem
<egg|laptop|egg> bofh: pretty sure if you go out in northern sweden when it's 0 deg C with a ton of wind dressed as if there were no wind at the same temperature, you learn fast :-p
<SnoopJeDi> "how cold must the air temp be in order to freeze eyeballs in a *living* human"
<egg|laptop|egg> (or s/0/-something/ as appropriate depending on the season)
<SnoopJeDi> intuitively, "extremely" but it seems like you could get a great guess with a rectangular (~cylindrical) heat equation
<SnoopJeDi> domain of water, body heat applied on 3 edges, air temp reservoir on the 4th
<bofh> but yeah I guess a lot of it is America is a big country and large parts of it have no idée how cold temps work, really.
<bofh> or at least *usually* don't, at least not for like, the absurd-cold ones.
<egg|laptop|egg> hm the cat is sparkly when petted
<egg|laptop|egg> it's usually not dry here
<UmbralRaptop> anbocations?
<SnoopJeDi> bofh, and the other meteorological quantities are going to vary
<SnoopJeDi> prevailing patterns, humidity, wind...
<SnoopJeDi> not sure how much texture there is in smaller nations, but I would assume it's substantially less because geophysics?
<SnoopJeDi> shoot, we have drastically different climates in just this *state* :P
<SnoopJeDi> (happy National Texas Day?)
<egg|laptop|egg> not sure there necessarily is a reason other than "someone thought it was a good idea to factor this into the temperature and now everyone is used to it"
<SnoopJeDi> well I agree with bofh's reasoning that the average people isn't interested in learning to consider multiple quantities (regardless of how one feels about that)
<egg|laptop|egg> you'll easily get lots of variability within e.g. mediterranean countries with mountains
<SnoopJeDi> or perhaps the average *American* isn't
<SnoopJeDi> we have a uhhhhhhh very mottled meteorological history
* SnoopJeDi glances at Galveston
<egg|laptop|egg> well, it's not directly driven by the interest of those who listen to the forecast
<SnoopJeDi> perhaps that's what we disagree over
<egg|laptop|egg> i'm not sure we're disagreeing over anything
<SnoopJeDi> well, I disagree that it's not "directly driven"
<egg|laptop|egg> those who listen to the forecast are not those who write it
<SnoopJeDi> it's the only reason I can think of to include "feels like"
<egg|laptop|egg> there is an indirection
<SnoopJeDi> oh, sure
<SnoopJeDi> it's indirect in that sense that viewership is the linkage
<egg|laptop|egg> the person who comes up with "feels like" makes a hypothesis about what those for whom they write want to read
<SnoopJeDi> but this is the reality of popular weather
<SnoopJeDi> (if it weren't, we'd get confidence intervals?)
