stabs a headache, and wonders if this is another cold
<egg|anbo|egg>
iximeow: hm the sky looks kinda clear
<egg|anbo|egg>
but my knee hurts so I'm not going to lug the scope out
<raptop>
!8 is egg|anbo|egg getting old?
<galois>
raptop: no
<egg|anbo|egg>
raptop: stacked 5 steres of wood
<iximeow>
egg|anbo|egg: let me know how betelgeuse looks!!
<egg|anbo|egg>
raptop: so i think it's lifting cartloads of wood rather than age
<egg|anbo|egg>
iximeow: okay I'll take a look
<raptop>
!wa 1 stere in cords
<raptop>
;wa 1 stere in cords
<kmath>
raptop: convert 1 stère to cords: 0.2759 cords
<kmath>
egg|anbo|egg: convert 5 stères to cords: 1.379 cords
<egg|anbo|egg>
raptop: the cord is the right kind of unit, in that it also measures stacked wood including air (although contrary to the stere it seems less specific about the length of the logs)
<egg|anbo|egg>
the stere is specifically to be measured in 1 m logs, because in 50 cm logs you get 0,8 m^3 once stacked (more logs means it packs more densely)
<egg|anbo|egg>
iximeow: hm, it's clouding over actually
<iximeow>
boo
<egg|anbo|egg>
iximeow: seems markedly dimmer than Procyon, modulo clouds, which is not super useful data
<raptop>
No, bad clouds
<raptop>
Hrm. Is Aldebaran visible?
<egg|anbo|egg>
not from my bed
<egg|anbo|egg>
let me go out and have a look again
<raptop>
Obviously there's Rigel, but I'd like to compare against another orange/red star
<egg|anbo|egg>
raptop: clouds
* raptop
ponders pollux
* raptop
stabs the sky?
<egg|anbo|egg>
either it's clouds or betelgeuse has blown up, as well as everything else
<egg|anbo|egg>
raptop: isn't rigel much brighter?
<egg|anbo|egg>
anyway, clouds
<raptop>
egg|anbo|egg: I want to say it's filter dependent
<egg|anbo|egg>
aaa
<raptop>
Yeah, it's very filter dependent. Only ~0.3 mags in V band
<raptop>
B8 vs M1-2, so that's to be eggspected
<raptop>
If I'm reading simbad correctly, Betelgeuse is brighter in R through K, whil Regulus is a lot brighter in U and B
* raptop
ponders finding bolometric figures
<egg|anbo|egg>
> raptop wait, that's like 5 tonnes
<egg|anbo|egg>
hm I wonder how heavy it is
<egg|anbo|egg>
I also stacked it on top of used kitty litter to keep it dry (mud rots logs fast), so I also carted that around
<egg|anbo|egg>
raptop: apparently a stere is about 500 kg in dry wood
<egg|anbo|egg>
raptop: so 2 and a half tonnes of wood, I guess
<raptop>
hm
<raptop>
less dense than I thought

raptop: it's logs, not cubes; there's a lot of air

<sigfig> i can read french when mathematicians are talking about math, or when philosophers are talking about philosophy, but in no other context

B787_300: any idea why Ariane 4 2nd stage used cold-gas ullage pressurization (PGF) with helium, while it used hot-gas (PGC) for the 1st stage (and the PALs) with GG exhaust mixed with water?
<B787_300>
nope
<B787_300>
maybe to simplify construction
<egg|anbo|egg>
hm
<egg|anbo|egg>
B787_300: the 2nd stage is single-engine, so uses GG exhaust to control roll
<B787_300>
heat exchangers are a pain and you need lots of piping to get from the gas bottles to the engine then back, also for expander cycle engines all heat is needed to drive the turbine
<B787_300>
oh S2 is GG
<egg|anbo|egg>
yeah
<egg|anbo|egg>
it's all Vikings
<egg|anbo|egg>
would roll control use too much of the exhaust to pressurise with the rest?
<B787_300>
wait they were taking turbine exhasut mixing with water to pressurize the tanks!
<B787_300>
because unless there are diaphragms that sounds like a TERRIBLE idea
<kmath>
<alt_kia> oh the gas generator exhaust (diluted with water) also gets used to pressurize the main fuel/oxidizer tanks; hopefu… https://t.co/lHAHx8Qruq
<egg|anbo|egg>
B787_300: well, hot as in "exhaust"
<B787_300>
i mean the hotter the gas is the less you need to carry
<egg|anbo|egg>
right
<egg|anbo|egg>
B787_300: I mean the reason why you don't run your GG stoichiometric is temperature, here the GG has water injected right in the chamber, so I guess they might be getting around it like that?
<B787_300>
ugh that would make the tank heavy as it needs to hold the pressure, where as the prop tanks are normally held at a lower pressure just to stop cavitation on the pumps
<egg|anbo|egg>
yeah (then again a helium tank would also need to be heavy and pressurized)

I'm getting the impression that computers are powered by a bunch of safe/euclid class SCPs
