@IceLord I'm pretty sure @JohnRennie is the face of physics.SE to much more people ;)
 
user218912
my first experience with this site was ACM downvoting my first question and commenting about how it's low quality.

@ACuriousMind And qmechanic! "Possible duplicate of ___" is the thing many new users first see :)

"$\bullet$ is the Schwartz multiplication in $\mathcal{D}' (\Omega)$"
 
ACuriousMind
ACuriousMind
@NeuroFuzzy Right!
 
Slereah
Slereah
I thought there was no Schwartz multiplication

10:01 PM
Having your tags edited by Qmechanic is probably the first rite of passage
 
Slereah
Slereah
That's literally the point of the impossibility theorem
 
user218912
idk about you guys but I didn't know about Qmechanic or JR until later. I only saw ACM everywhere.
 
user218912
this is about 5 months before I came to the chat.

Well technically it's $^\star D'$
I guess it's possible

10:02 PM
Ah, Morte. Good times.
 
user218912
btw @ACuriousMind you never had a blue profile image :(
 
Slereah
Slereah
Planescape was breddy good
 
user218912
you don't like blue?
 
ACuriousMind
ACuriousMind
@IceLord I'm not picking the pictures for the colours, but for the characters in them
I guess it just so happened they rarely have a blue colour scheme
 
user218912
@ACuriousMind well... do you know any blue characters? XD
 
ACuriousMind
ACuriousMind
10:05 PM
@IceLord Aside from Liara the Asari from Mass Effect I struggle to think of any
 
0celo7
0celo7
I have a crush on Liara
@ACuriousMind link me the place to vote and I'll vote for you.
 
user218912
@ACuriousMind that should definitely be your next profile image.
 
user218912
it looks suitable.
 
ACuriousMind
ACuriousMind
@0celo7 1. You can't vote yet. 2. I have faith you'll find that on your own.
@IceLord I don't like her as a character, though.
 
user218912

@ACuriousMind did you play persona 3 ever?
 
0celo7
0celo7
I don't care enough to vote unless someone sends me the link.
 
ACuriousMind
ACuriousMind
@0celo7 Then maybe it's better you don't vote :P
 
0celo7
0celo7
Maybe.
I'm too much of a nihilist to care about petty things like site policy.
And the fact that I don't know any physics or use the main site.
Oh my god
am I really a nihilist
 
Bernard Meurer
Bernard Meurer
@0celo7 You are
 
0celo7
0celo7
How do I fix it
 
Bernard Meurer
Bernard Meurer
10:12 PM
@0celo7 Start caring about things & people I guess
Or perhaps that's not it
Find meaning in the things you do
there
 
0celo7
0celo7
I care about certain people and things
 
Bernard Meurer
Bernard Meurer
But do you see meaning in what you do & the things around you?
 
user218912
@0celo7 I added you on skype, I forgot my old acc details.
 
0celo7
0celo7
No
@IceLord I don't use Skype

@0celo7 Then find it & quit being a nihilist

@BernardMeurer I'm scared that I'm a hardcore misanthrope
 
Bernard Meurer
Bernard Meurer
10:16 PM
@0celo7 You seem to be fairly misanthrope
 
0celo7
0celo7
How do I tell for sure?
 
Bernard Meurer
Bernard Meurer
@0celo7 Do you despise people?
 
user218912
look at yourself in a mirror
 
0celo7
0celo7
Some people very deeply.
 
user218912
hope that's not me :o
 
0celo7
0celo7
10:18 PM
@IceLord Not right now, no.
 
user218912
because I ask some pretty dumb questions.
 
user218912
okay :D
 
ACuriousMind
ACuriousMind
@BernardMeurer Why do you keep saying "Vermin Supreme"?
@0celo7 I think if you're scared of that, you're not a hardcore misanthrope
 
0celo7
0celo7
@ACuriousMind He's a troll 3rd part candidate in the US.
His platform is ponies for everyone.
@ACuriousMind Maybe more curious. I'm too much of a nihilist to be actually scared of it.
Oh my god what is wrong with me
 
ACuriousMind
ACuriousMind
@0celo7 That much I gathered from my use of the Almighty Google, but I'm not sure why @BernardMeurer keeps bringing him up
 
user218912
10:20 PM
@Slereah what was the image of a sparkly cat you posted a few months ago?
 
user218912
can you post it again plz.

What does the convolution operator do
$\star : D'(\Omega) \times D(\Omega) \to E(\Omega)$
Is it the same as the usual convolution?
Hm, I suppose it is
 
ACuriousMind
ACuriousMind
@Slereah Honestly, whom here do you expect to know that? :D
I'd wager no one has read the things you're reading
 
Slereah
Slereah
Do the convolutions of distributions and test functions always give smooth functions?
You never know
 
ACuriousMind
ACuriousMind
10:38 PM
@Slereah I think in general it will only give a distribution.

@ACuriousMind Too busy to stay and chat, but saw the nominations thing and you have my vote sir. I think you would make an excellent moderator :)

Huh @ACuriousMind I thought we can mollify distributions by convolution
 
ACuriousMind
ACuriousMind
@StanShunpike Why, thank you!
 
0celo7

@Slereah Maybe read Rudin and Evans before doing whatever you're doing.

@0celo7 Hmmm
You might be right

Sorry, I just made that joke on my complex analysis homework and had to make it again.

Are you taking geometry yet?

@0celo7 This will be long

@BernardMeurer I think 0celo7 wishes that you communicate in complete natural sentences instead of mathematical shorthand
 
Bernard Meurer

@ACuriousMind Got it

0celo7
Yes pls
 
Bernard Meurer
Bernard Meurer
There is an $n$ in the naturals such that, for $b,a\in\mathbb{R}$ and $a>0$ the product of $n$ and $a$ is larger than $b$
Make sense?

No, you can write n in N
And you don't have to write the product of

@0celo7 Deal
I'll go back to chemistry then

10:52 PM
PhD quantum mechanics you mean
@NeuroFuzzy you're lucky I'm on a phone and can't parse that in my head.
 
Bernard Meurer
Bernard Meurer
@0celo7 Lol, yep
 
0celo7
0celo7
I suspect heartsuit isn't nice.
@NeuroFuzzy what does that even mean
who writes $\forall_x$
it's $\forall x$
@Slereah Robinson?

11:12 PM
@0celo7 I think $\forall_x$ looks way nicer haha
 
0celo7
0celo7
@NeuroFuzzy Wat. Literally never seen it
Then again most books I have don't write it
 
Slereah
Slereah
Then you don't have any books worth reading
 
ACuriousMind
ACuriousMind
Let's do $\forall_x^{\in A}$ for maximal notational confusion :P

Slereah
Oh
I remember
The best paper
By Schonfinkel
He tried to derive the most compact logical notation possible
First replacing all logical operators with Schaeffer's stroke
Then using reverse Polish notation
then including quantifiers in the operator
He used $|^x$ as $f(x) |^x g(x) \equiv \forall x. \neg (f(x) \wedge g(x))$
Then since every proposition used the same operator and only the order mattered, he rewrote everything as logical combinators
And so he wrote all of first order logic using only three symbols

Q: What are specific qualities that you need to be a moderator?

heatherI am asking this for two reasons - one, so I can see how to vote; i.e., what is important, and two, to just see what I need to do to get to this level of "helpfulness" (not necessarily being moderator) to the physics.SE community. What specific qualities do moderators need? I.e., how much time s...

ACuriousMind
ACuriousMind
@Slereah But...why? :D
 
Slereah
Slereah
It was the 20's
It was still back when people thought that having the smallest logical system would have some sort of use
 
Sir Cumference
Sir Cumference
@0celo7 Huh, you didn't nominate yourself for moderator?
 
ACuriousMind
ACuriousMind
@Slereah I guess they then realized that size doesn't matter?

@SirCumference huh, why would you expect that?

I have found a rule of thumb that basically you cannot have a decent turing equivalent system without five Things
 
ACuriousMind
ACuriousMind
@DanielSank You misspelt "janitor" ;)
 
Slereah
Slereah
11:36 PM
Logical combinators need three symbols and two transformation rules
OISC need three symbols and have two branching cases
 
DanielSank
DanielSank
@ACuriousMind Oh come on.
 
Slereah
Slereah
The 2-3 state machine has it right in the name
The smallest version of Brainfuck that will work has about 5 symbols
etc
 
Sir Cumference
Sir Cumference
But yeah, when my friends ask me "how small is an electron", I reply "Have you ever heard the phrase, 'size doesn't matter?' Quantum mechanics takes it literally."
Also good luck @ACuriousMind
 
ACuriousMind

@DanielSank I couldn't think of a cleverer reply :P
@SirCumference Thanks, although I'd be perfectly happy to not get elected if certain other people step forward.

@0celo7 Obligatory remark: This isn't a forum.
 
Sir Cumference

11:45 PM
@0celo7 I don't think moderating the site and removing the garbage has to do with liking physics
It's the same reason you hang around in the chat
 
0celo7
0celo7
@ACuriousMind Ah, of course not.
 
ACuriousMind
ACuriousMind
@SirCumference But why would you do it if you didn't really like physics or use the site?
 
Sir Cumference
Sir Cumference
@ACuriousMind You like the community?
Willing to help, I guess

I defer to my topology prof, who suggested the Math Stack Exchange and Math Overflow forums for help with my compact open problem

11:49 PM
@SirCumference Possible, but I'm not sure that's the case for the self-professed misanthrope @0celo7 :P
@0celo7 And did you post a question there yet?
 
0celo7
0celo7
Self-possessed? What does that mean?
@ACuriousMind No, I figured it out the old-fashioned way.
 
Sir Cumference
Sir Cumference
Regardless, I'm okay with whoever wins this election. The U.S. election, on the other hand, is making me feel worse and worse.

Nope

Hmm.
I swear it said possessed a second ago.

ACuriousMind
Although you being possessed might explain a few things
 
0celo7
0celo7
What does that mean?
Crap. Linear algebra on my analysis homework
@ACuriousMind halp
 
Sir Cumference
Sir Cumference
@0celo7 Still no idea how you can dislike physics

@0celo7 You'll have to be a bit more specific what you need help with

@ACuriousMind I don't accept AoC and I think I need a basis on the Banach space

Well, I'm not going to support your anti-choice position, either
