bofh: today in "phl is good", discussed this a - √(a² - b²) thing: the answer is "multiply by the conjugate expression", (a - √(a² - b²))(a + √(a² - b²))/(a + √(a² - b²)) = (a² - (a² - b²))/(a + √(a² - b²)) = b²/(a + √(a² - b²)) which is nice to compute
<egg|afk|egg>
UmbralRaptor: I first read that as 201,250=201250/1000, which confused me, then thought it was two numbers, comma-separated, then figured it out *stabbity stab the use of either . or , as a thousand separator*
egg|afk|egg is now known as egg
<e_14159>
egg|afk|egg: \, as a thousand separator?
<egg>
e_14159: yes, they do that in en-US at least
<e_14159>
egg: No, I meant "How about using LaTeXs small non-breaking space as a thousand separator"
<UmbralRaptor>
Can confirm, we do.
<egg>
(multiple CGPMs explicitly prohibit the use of either . or , for that)
<egg>
e_14159: I'm fine with the swiss-currency style of 123'456
<egg>
(with either . or , as the decimal mark, depending on whether it's in de-CH or fr-CH)

(Switzerland: it's complicated)

We did get some totality in St Joseph yesterday, by the way!
<SnoopJeDi>
(in case you were waiting on bated breath for the last 20 hours?)
<UmbralRaptor>
Yay (despite the rain?)
<SnoopJeDi>
Yep! Clouds let up a teeny bit right at totality. We still had a through-clouds view so it was hard to tell what was corona and what was cloud, but it was still pretty transcendental.

bofh: wondering how to denote rounding in the comments eggsplaining my numerics
* egg
tempted to use 【 】 :-p
<bofh>
well floor is ⌊a⌋ & ceiling is ⌈a⌉ so 【a】 for round-to-nearest ties-to-even seems sensible to me :P
<egg>
bofh: tbh [] seems the most reasonable given the above
<egg>
also nice in fixed-width code
<bofh>
yeah, that's the simplest thing to use, agreed.

bofh, I had to explain where Voyager is to my (~70 y/o) advisor today. I have some very mixed feelings about that.
<bofh>
?!
<UmbralRaptor>
o_O
<SnoopJeDi>
He apparently either didn't hear about it leaving the solar system or didn't care or...?
<SnoopJeDi>
He's a strange fella.
<UmbralRaptor>
(unless explain as in detailed RA&Dec)
<SnoopJeDi>
nah he just had no idea it was in interstellar space
<SnoopJeDi>
I mentioned the documentary to him because I was considering hosting a student watch event in the department

SnoopJeDi: GMU just has fossil displays in this building.

UmbralRaptor, did I tell you we have one of Madame Curie's samples chilling by our campus's TRIGA reactor?
<UmbralRaptor>
!
<SnoopJeDi>
(it was pretty much the only place on campus that it could be housed)
<SnoopJeDi>
like you can walk over to look down on the core and see the Cherenkov, and on the same level there's this nondescript wooden box with a plaque and a purple-ish glass capsule
<SnoopJeDi>
for the life of me I cannot recall what the source actually *is* now
<bofh>
pitchblende?
<bofh>
(apparently it's called Uraninite now)
<SnoopJeDi>
Nah, it was something pretty pure I think. Presumably something with an α channel, I'd think the discoloration is because of neutron damage
<SnoopJeDi>
It definitely is marked on the placard but that's a fairly access-controlled area and there isn't anything online about it I think
<SnoopJeDi>
bofh, it tickles me to no end that Jáchymov is also the etymological birthplace of the word "dollar" :D
<bofh>
SnoopJeDi: wait what?
<bofh>
(also like Po-210 is a pretty pure alpha emitter so)
<SnoopJeDi>
bofh, apparently the same town where Curie got her pitchblende was known as Joachimsthal, and the silver coins minted therefrom where known as Joachimsthalers, which got truncated to "thaler" and from there it's a short ride to "dollar"
<bofh>
I like how the first part of that name just got truncated completely.
<SnoopJeDi>
apparently it means "Saint Joachim's Valley" so I guess "thal" maps onto "valley"
<SnoopJeDi>
the way Veritasium told the story in his PBS special, it was a site of import in the "race" for a bomb
<SnoopJeDi>
and later a popular site for its radon spas
<bofh>
radon... spas...
<bofh>
why
<bofh>
nevermind, we had radioactive toothpaste once.

I mean that's a *lot* less than 66TBq but I like that someone has at least attempted to make this a reality.
<SnoopJeDi>
speaking of animal glands and revitalising your man-bits
<SnoopJeDi>
bofh, whitequark are either/both of you aware of the podcast Sawbones?
<SnoopJeDi>
it isdelightful
<bofh>
nope
<SnoopJeDi>
doctor takes a trip down medical history ave. with her comedian husband
<bofh>
that sounds awesome
<SnoopJeDi>
the first episode I listened to was about this guy who was *super* into transplanting goat...uh, bits...so that animal gland bit made me think of it
<SnoopJeDi>
And it definitely seems up your alleys in terms of "oh jeez what"
<SnoopJeDi>
Pliny the Elder is mentioned in pretty much every episode, to great comedic effect
<bofh>
might be worth a listen, I wonder if it has transcripts for what it's worth?
<SnoopJeDi>
Hmm, not sure they keep any show notes. Sydnee seems active on Twitter though, would probably respond to a ping
<SnoopJeDi>
oh and neat, they did an episode on the Mütter Museum last month
<bofh>
no big deal, I'll just listen to the podcasts then :P (if transcripts are available tho I prefer reading them)
<whitequark>
^ i don't have the attention span to listen to podcasts
<SnoopJeDi>
yea at a peek it looks like not so much, which is a shame because the prep she does is damned thorough from what I can tell
<SnoopJeDi>
whitequark, same, I go through spurts which largely coincide with long drives

End up avoiding almost anything serialized because I just don't want to set aside that much time/energy

same.
