what character table
 
I'm already confused
wtf is this magic
 
do you not know what a charater table is?
 
no
no repn theory
 
it's the list of traces of simple representations
 
@Blue ::sigh:: Thanks, it's nice to know that I'm probably not a raving lunatic at least
 
11:01 PM
$\phi(\zeta) = \zeta ^n + a_1\zeta ^{n-1}... a_n = 0$
What the hell is this I don't understand
This just seems arbitrary
 
woaaaaahhrhrhhrhhrhrhrhrhrhrhr
rhrhrhhrhrhrhr
 
black science man!
yikes
that meme is so deep fried it's charcoal
 
could probably still sell it to an american
If you can convince a country to spell "colour" wrong, you can sell them deep fried charcoal
I'm not bitter or anything
Could someone please explain to me what it means for a linear operator to be defined like above?
 
Brits are crazy. How can more letters be a good thing?
 
@0ßelö7 did you get my skrrrra meme
or do you live under the rock
 
11:03 PM
@BalarkaSen No.
 
sigh
 
Skrrrrrrrrrrrrrrrt pop pop
it's old Balarka I'm sorry
 
not for 0celo7
@Phase you know what's fresh? asian jake paul
 
my name is very close to Jake Paul
and it causes me great despair
 
@0ßelö7 listen to this
 
11:04 PM
I know that
I just don't consider it a part of the meme world

Can you imagine someone unfortunately named "Jake Pauler", born at a date that makes them around 15 or 16 near the time of his peak
@Blue >first name
 
is that supposed to be good rap
 
11:06 PM
@0ßelö7
Your "women" comment is starred
 
pretty inferior compared to ATL stuff
 
You're gonna get got by the meme police
 
fuck
 
Can we analytically continue the rational men, to the set of irrational women?
 
getgetgetgotgotgot
 
11:07 PM
@Catija @Jefromi can you please remove this trash from the starboard
 
bloodrushtomyheadlitlocklock
 
@0ßelö7 if you say the entire starboard will be wiped
specify what trash you want gone
 
@Catija @Jefromi my message and the one about masturbation
 
Whoa hold up
Hol up
 
sit down
 
11:10 PM
@BalarkaSen this Shoen-Yau paper is scary
it's GMT ;_;
 
I can't hear that without remembering the Chocolate Raisins
 
I always hear Syrup Sammiches
 
@BalarkaSen I've got 3 months to understand this paper
Do you want to learn GMT in the meantime and help?
 
Typical american
doesn't understand GMT + 00
 
11:14 PM
@BalarkaSen It has Federer in the references
 
good grief. I will do some cleanup, but seriously y'all, maybe learn not to star crap? and maybe sometimes avoid saying it in the first place?
 
honestly
 
@Jefromi There are elements among us that like to watch the world burn
 
just delete the quote of Hilbert
That's the offensive part here
 
@Phase NO
 
11:15 PM
It offends me
I was born as a Hilbert space without an inner space norm
I can't stand seeing quotes from that monster
Honestly
Is reading Dirac's Principles as a first education in QM Just a meme or what
He goes into voodoo shit right near the start
and his notation is from the stone ages
 
@BalarkaSen I didn't think through using Hatcher and Bredon as furniture
I need to look up what the hell homology is again
 
14
A: Study Quantum Physics

Ron MaimonJust pick up Dirac's book "The Principles of Quantum Mechanics" and read it in conjunction with "The Feynman Lectures on Physics Vol III". Don't waste time with linear algebra, the entire content of the undergraduate courses can be learned in half a day. Don't worry about the infinite dimensional...

 
legit it's an actual question
 
@0ßelö7 rekt
 
14 messages moved to Trashcan
 
11:20 PM
14?
 
@Phase well, I don't know who it was, but collectively the room demonstrated an inability to stop starring messages from 1-2 hours ago that look ugly out of context
so the other candidates for such treatment are gone as well.
 
Collectively?
 
and why was it moved to trashcan
 
Hey, I didn't star anything.
 
rather than trash
It doesn't come across particularly transparent
 
11:21 PM
@0ßelö7 yes, as in "the set of users who are looking at this room among themselves managed to accomplish this"
 
@Jefromi I didn't do anything
 
@Phase because it's gone, it's a way to delete without leaving a ton of deletion stubs.
 
Why am I in the line of fire
 
You aren't. I never named you, and I merely replied to your message.
 
@BalarkaSen the de rham theorem is insane
 
11:23 PM
@Phase There is no policy for providing access to deleted chat messages, any more than we do so for deleted comments on the site.
 
@lılostafa I don't want to just do Undergrad, I want an understanding, but while I've heard great things this book goes into voodoo shit imminently
 
I've learned the proof via hard work a la lee and the sheafy proof
I still don't understand how it works
 
It's an easy corollary of the Hodge theorem
 
no that one
the one that says smooth singular and singular and de rham are all the same
 
No, sorry, its not
 
11:24 PM
@Jefromi But what about others who weren't in the room when all these happened and may want to follow it tomorrow?
 
I was thinking about Poincare duality
 
good afternoon everybody
 
@BalarkaSen Oh some people call $H^k\cong\mathcal H^k$ the de Rham theorem
 
@0ßelö7 The map is given by like $H^k(M) \times H_{n-k}(M) \to \Bbb R$ sending a $k$-form and a $(n-k)$-cycle to the integration of the form over the cycle isn't it?
 
Hello Christian
 
11:25 PM
@BalarkaSen No, it's inclusion
 
And then you prove that's a nondegenerate billinear pairing
So $H^k(M) \cong \hom(H_{n-k}(M); \Bbb R)$
 
@Phase A good undergrad will give you a good understanding, as far as such a thing can be achieved in a few years - it just takes time for things to sink in - we had a saying that you only really understood something 2 or 3 years after doing the course, preferably having had a part in teaching [supervising] it to someone else
 
oh fuck, there's like 20 de Rham theorems
 
rhs is isom to singular $H^k(M)$
 
@lılostafa If you'd like to discuss this, I'd suggest a different room; people seem to be using this room for actual physics things.
 
11:26 PM
@0ßelö7 huh?
 
@Mithrandir24601 did you read the linked answer?
 
@Phase Yeah and I'd say that the fundamentals are the most important thing
 
@Jefromi we're cool with discussions like that
 
@BalarkaSen I'm looking at $H_{k,\text{singular}}\cong H_{k,\text{smooth singular}}$
 
It's the night, mods are asleep post crank shit
$pi = 3$
 
11:27 PM
well once you know for cohomology you know for homology
 
@Phase I've never read either of the books mentioned, but you need to learn the fundamentals
 
universal coefficient theorem
 
@BalarkaSen oh no, please
 
Yeah but it said "dont bother with linear algebra"
 
If I have to know that I will abandon whatever else I'm doing
 
11:28 PM
 
Wait a minute. What does deRham homology even mean?
 
@Jefromi ...this is not physics
@BalarkaSen nothing
 
deRham's theorem is inherently a statement about cohomology
 
I said this was a different de Rham theorem
there's a lot
 
well boo
@0ßelö7 This should not be hard.
Whitney approximation theorem
 
11:29 PM
I think the uber official de Rham theorems says de Rham and simplical cohomology are isomorphic
 
says you can perturb everything arbitrarily small to be smooth
 
what even is universal coefficient theorem
 
simplicial/singular/cellular are all isom
 
I have tom Dieck here
singular/simplician
I can't remember what these are
 
It says 0 --> Ext(H_(n-1)(X), G) --> H^n(X; G) --> Hom(H_n(X), G) --> 0 is exact
 
11:31 PM
what does that have to do with cohomology
 
There, fixed
 
hmm
 
@0ßelö7 im removing my star from mr hilbert
have a good day
I t s
t o o
l a t e
:(
 
what are you on about
@BalarkaSen I will read the paper and see what's actually going on
 
Anonymous
@Phase Make some smart star-able comments so that that message gets hidden =P
 
11:35 PM
hm
haha pee pee poo poo maths is great physics suks lol
I'll just wait until this starts approaching infinity
 
@Phase I disagree with that :P You're going to have to pick it up in some form or another at some point if you want to actually do physics. I mean, linear algebra is extremely close to QM
 
Anonymous
I'm getting dank video recommendations by YT today: youtube.com/watch?v=M4LWw7Jpij8
 
@Phase Although, if you're going to take advice from a physicist about how best to learn physics, it's generally a good idea to listen to the people who publish the best stuff. They so happen to be University lecturers and Profs, who, guess what, teach linear algebra to everyone doing QM. If they turn round and say that it's not necessary, then fair enough
 
@Blue beautiful
 
@Blue Nice
 
11:43 PM
In any case, in literally everything I have ever done in my life, learning the fundamentals has been the most useful thing, even if it's not particularly interesting
 
You need to learn Bourbaki-style linear algebra to be a good physist
physist? Ok I'll roll with that
You need to learn it very rigorously
There are no matrices, only linear transformations
By which I mean morphism in the category of k-vector spaces
k is a field. In general non-Archimedean
 
@BalarkaSen can u teach me PDE like Bourbaki would?
 
Once you accept that, @Phase, only then you will be a good physist
 
Just two months ago, I was linearising matrices in order to derive a thing :P
 
@0ßelö7 "Teach me like one of those French girls"?
 
11:47 PM
@BalarkaSen ugh no please don't get naked
 
Anonymous
We seriously need a Naked Mathematician
 
@0ßelö7 I would ask something at this point because I'm not a PDE expert but maybe that'd be inappropriate
 
"the subset of 3-metrics on $(\Sigma,\hat e)$ such that $R(g)=0$, $g-\hat e\in H^2_\delta, -3/2<\delta<-1/2$ forms a $C^\infty$ submanifold $\mathscr C$ of $H^2_\delta$"
oh wonderful
infinite dimensional manifolds
 
seriously, who is starring that message from an hour before?
 
I don't know
 
11:49 PM
which
 
the one by Jefromi
 
Probs the other mods
 
there are some white knights who not only flag stuff but also star retaliatory messages
 
Meanwhile Im just here trying to star my own messages
Shog I prayed to you
why betray me
 
@lılostafa I did, because it is a truth all of you should keep in mind more often.
 
11:51 PM
@0ßelö7 retaliatory messages?
 
@ACuriousMind All of you? Why the hell am I being dragged into this
 
@ACuriousMind I knew
 
ACM did you draw that pfp?
It's actually really nicely made
 
But who is the other one?
 
its a game character as usual
i have a better avatar
 
11:51 PM
@ACuriousMind I'm about to try to make Schnitzel without a >50 year old European lady helping
wish me luck
 
@BalarkaSen what is it
 
@Phase "pfp"?
 
grease fire incoming

11:52 PM
@0ßelö7 don't let your hair touch the stove
r o a s t
 
@Phase it's a lonely russian fox
 
NWN?
 
@Phase I have short hair
 
@Phase took me ~10 seconds to realize it
 
Me too Snap
 
11:53 PM
Long hair on men just hinders combat ability
 
>named after Ocelot
>shittalks long hair
ok
 
his hair is shoulder length
you were implying waist length
 
those are good for headbanging tho
 
@0ßelö7 Are you trying to say women's combat ability is not as good as men's?
 
11:54 PM
@BalarkaSen Headbanging does not help when the UN invades
@lılostafa Yes
 
must resist urge to star
 
i lold out loud
 
What is wrong with you people
 
everyone who didnt do that
raise your hand
don't type, just do it irl
 
Anonymous
Depends on the type of combat obviously. :P
 
11:55 PM
Knitting Combat
 
@Blue Hand to hand
Only blunt weapons
 
What about something with six shots
but is enough to put down anything that moves
 
what about kung fu
 
:40405863 Why did yu delete that
 
@BalarkaSen What about it?
 
11:56 PM
@lılostafa Because "destroy" is likely not family friendly.
 
everyone's talking about types of combat so why not kung fu
 
@BalarkaSen Wing Chun is invented by a girl
 
i believe you
 
I think that the statement: "The average man can soundly beat the average women in hand to hand combat." is ok
 
@Phase Neverwinter Nights.
 
11:57 PM
@ACuriousMind if not, let me know
 
@BalarkaSen Only, that's not a type of combat - you've just said "what about Chinese martial arts" :P
 
@0ßelö7 "ok" in what sense? What purpose do you have in stating it?
 
@ACuriousMind Context doesn't matter to the flag, so I don't think that's a good question
...
 
Also, @BalarkaSen much of what most people think of as Kung Fu is form work, i.e. not combat :)
 
erase from existence is pretty hard
 
11:59 PM
@Mithrandir24601 i dunno man im not into hand to hand combats
i didnt know that
 
@BalarkaSen you're not the average man LOL
 
@BalarkaSen I happen to do kung fu ;)
 
@0ßelö7 exactly, im not a normie
 
@0ßelö7 If your sole concern in posting something here is whether it might get flagged or not, I might suspect you are not partipating in good faith in the first place.
