6:00 PM
@Sawarnik: That is why I'm asking you, silly.
 
Oh, oh. Wat, Nick doesn't know it ... ow.
Ok, here it is:
 
hello people
 
hiya
 
$$\frac{a_1+a_2+...+a_n}{n}\ge \sqrt[n]{a_1 a_2 ... a_n}$$
@Nick Don't tell me you didn't know this thing.
 
@Sawarnik wassup bro?
 
6:01 PM
Triangles.
 
@Sawarnik: Ok, the AM $\geq$ GM ...? Is that it?
 
Yeah!
 
hold on... arithmetic and geometric mean?
 
Yeah.
 
@Nick troll!!!
:P
 
6:02 PM
@Huy Still here?
 
@Sawarnik: I'm a dumdum, di you have gumgum?
@AwalGarg: I seriously didn't understand it when the guy answered.
 
Huy
@Sawarnik: Depends. What do you need?
 
@Nick haha ok nvm
 
r9m
@Sawarnik SIGH !!!
 
@Huy Some hints to your gf problem :D
 
6:04 PM
just came lurking here... gotta go now. cya later :)
 
@r9m lol .. :P .. sorry.
 
Huy
@Sawarnik: It will soon be declared a Millennium problem.
 
bye @Awal.
@Huy Wow... so you will get some million dollars?
 
@AwalGarg: No lurking. Only @IceBoy is allowed to lurk in this room. He does it like a gentleman too.
 
lol^
 
Huy
6:05 PM
@Sawarnik: As soon as my parents die, yes.
 
Mhh, maybe I'm a hypocrite.
 
@Huy What if they outlive you?
 
Huy
@Sawarnik: Then my bro gets all the money.
 
And would you let me be the third in order? :D
 
@Huy: Are your parents math/phy/chem people?
 
6:06 PM
Genius people I think though.
 
@MarcGato I haven't studied that much topology, sorry.
 
@Balarka here, in attention everybody!
 
@Sawarnik: If you try to kill off @Huy's brother, I swear I'll cut off your asymptotes.
 
@Nick My asymptotes? Ouch .. anyway, how is done?
 
Huy
@Nick: No.
 
6:09 PM
Hello @Nick @Huy
 
^ :(
 
@Sawarnik: You don't want to know.
 
I want to know.
 
Huy
@Sawarnik: In the city where I live, almost 30% of all people are millionaires. They're really not that rich, compared to the rest here.
 
@Huy: Well then, they'll definitely outlive you.
 
6:10 PM
Contrast with how poor you are.
@Huy When can I expect a solution? 20 days? :D :O
 
Huy
@Sawarnik: You wish.
 
@r9m When will I be getting the solution to the other question [in good faith] :)
@Huy 20 days?
 
Huy
Never.
 
21 days?
 
@G.T.R!
 
r9m
6:13 PM
@Sawarnik okay O-O there .. posted one ..
 
@BalarkaSen can you solve the equation $a^4+b^4+c^4+d^4=1000a+100b+10c+d$ for $a,b,c,d\in \{0,1,\ldots,9\}$ and $a\neq 0$ ?
 
@BalarkaSen :( Am I on ignore again?
@Huy 22 days?
 
Huy
@Sawarnik: Never.
 
@Huy: 24 days?
 
@Sawarnik: Think of it like a physics practical experiment. The Aim is something you know. The Requirements are: The process takes 7 days, requires a well, an integral snatched from Chris's sis, the eye of newt, sweat of ox, a demonic pentagonal star and Jigoku Shoujo dressed as the Ring girl. The procedure is something I cannot reveal. The result is left to your imagination.
 
6:15 PM
@G.T.R Such olympiadish. You can just use a program, you know. Just $10^4 - 10^3$ cases to check.
 
@Nick You mean you know?
:D :D
 
@BalarkaSen it should be done in less than 3 hours, no computers allowed
 
r9m
@BalarkaSen lolwa to that ..
 
@G.T.R Balark won't like that^ :P
 
@G.T.R OK, then it is an olympiad problem turns away
 
6:16 PM
see
@Nick Are you any good at stalking @Huy ? :D
 
@r9m PARI can do it in seconds
 
@BalarkaSen Not computers.
 
Hello @TedShifrin
 
@GTR !!! Salut!
hi @Balarka
 
@Nick Can you ask Balarka if I am on ignore?
 
6:17 PM
@Huy: Are you a hot teenage girl who can tutor me in Vector Algebra?
 
r9m
@BalarkaSen ofcourse .. but we are talking about using computers to check olympiadish questions .. (lolwa)
 
@r9m thanks :)
 
Huy
@Nick: Yes. Asl?
 
puts everyone on ignore
 
@BalarkaSen will never ignore @Sawarnik
 
6:18 PM
You sure? How?
 
r9m
@TedShifrin hello professor :)
 
hi @r9m
 
No, @Nick. He is on ignore forever.
I can't stand someone more obnoxious than me.
 
Now you know how we feel, @Balarka.
 
@TedShifrin Wait everyone was on ignore?
 
r9m
6:19 PM
@BalarkaSen blud !!
 
@BalarkaSen: I'm ok, right?
 
@Nick You're not obnoxious. Well generally.
 
@Nick See :((
 
@Ted Salut, j'ai vu ton derniers cours sur les 4 espaces vectoriels fondamentaux apparaître dans ma "My subscriptions" sur Youtube
 
C'est pas épatant, @GTR :)
 
6:20 PM
@BalarkaSen: ... really? Then, what am I? (in one word)
 
@TedShifrin So you agree that you are obnoxious to some extent?
 
Googles define obnoxious.
 
no, @Balarka, I agree that you are totally obnoxious
 
@TedShifrin Oh. I know that.
 
@TedShifrin true :D
 
6:21 PM
Bonjour @Ted.
 
But that guy Sawarnik annoys people.
 
I think I'm remarkably patient around here
 
@r9m How did you manage to become a friend on FB? :D
 
Guten Abend, @DanielF
 
I agree that half the people in this room are egomaniacs :D
4
 
6:21 PM
^
 
r9m
@Sawarnik from G.T.R's friend list ! istalked =P
 
@BalarkaSen $$\huge{:(}$$
@r9m No well, Ted :D :O
 
Il me semble que @GTR ait trop d'amis :)
 
@r9m Can you stalk Huy btw? :P
 
@Nick As long as we're all comfortable with who we are and proud of what we do right?!
 
r9m
6:23 PM
@Sawarnik y ?
 
well, I'll come back when some math is going on ...
 
@TedShifrin bye :)
 
@Ted proving $C^0(\mathbb R)$ is infinite dimensional is really cool
 
you mean..i should go?
 
@GTR: I'm gonna talk for a day about Fourier stuff at the end of the course. I think I'll have time.
 
6:24 PM
@Huy: ... dude, I was trying to a prove a point. Now, take that last thing back.
 
@G.T.R Why? Which proof do you find the coolest?
 
Huy
@Nick: ASL?
 
I gave the obvious, insipid argument, @DanielF
 
@Sawarnik I don't have you as friend on Facebook, but I did find your profile some time ago
 
@G.T.R Oh wow, how was me? :)
 
6:25 PM
@TedShifrin Polynomials?
 
Let me find you...
 
@MickLH: 50% is a large population... if you get what I'm saying.
 
Yup
 
@Sawarnik young, short
 
:D
 
6:25 PM
They were already mind blown that a point could represent the entirety of a function, @DanielF :P
And, no, I didn't mention that with discontinuous functions one doesn't have a Hausdorff space :P
 
@TedShifrin Then showing that the restriction $C(\mathbb{R}) \to C([0,1])$ is surjective and $C([0,1])$ is not complete in the $L^1$-norm is probably not what you're going to do next time.
 
LOL, no, not with mostly freshmen ...
 
@Ted are you familiar with $\sigma$-algebras ? I remember you mentioned you'be teaching probabilities this year
 
But there will be a challenge problem soon using $\ell^2$ to see that $V^{\perp\perp}$ needn't be $V$.
 
@Ted that is very classic :P
 
6:28 PM
I'm teaching undergraduate probability, @GTR ... no measure theory whatsoever. But I used to know some of that stuff ... never my favorite. But DanielF knows it all.
Of course, @GTR.
 
@G.T.Rc Will you send me a friend request :D
 
@MickLH: psst.. I'll let you on a little secret, anyone and everyone can be termed as "liars, egomaniacal narcissists, hypocrites, etc." and it wouldn't technically be untrue because we are human beings and those qualities are a normal and natural behavioural response to certain situations we find ourselves in. Ultimately, we all just want to be loved and trusted.
 
True.
 
@Nick That's sortof touching on my humor :D
 
ok, I'm outta here ... Learn well.
 
6:29 PM
peace
 
Heal the World, brothers and sisters.
 
That human beings are capable of being rational and wise doesn't imply we're very good at it in practice.
 
Elvis has left the building
 
@Semiclassical Except Nick.
 
r9m
@Nick summons a priest .. wololo wololo (play aoe ?)
 
6:32 PM
@Ted but will you do some Baire ? Proving $R[X]$ has no countable basis is cool as well
@Sawarnik let me search my activity log
 
@G.T.R easier to search my name :D
 
I can't remember
 
@r9m Will you tell my fortune?
 
Jack can sing well but he can't dance. Jack is a failure because he can't dance but @Sawarnik only sees that Jack can sing. In this happy feet world, dancing is crucial.
 
r9m
6:34 PM
@Sawarnik kya ? kaise ?
 
@r9m The priest.
 
@r9m: Nah, Age of Empire is too time consuming. I once played Virtual Villagers for 4 months straight when I was 8.
 
@Nick :D
 
I'll never go back to gaming :|
 
Huy
@Nick: AoE is awesome though.
 
6:35 PM
@Nick I have played Age of Empires too .. it used to be awesome :) :D
And I'll never go back to gaming as well :| :|
 
r9m
AOE is awesome .. !!
 
Definitely..!
@G.T.R You look smart :D :D
 
$\text{awesome} = \frac{1}{2}\text{awful}$ ? Sounds to me that the word awesome just means not very bad.
 
r9m
@Sawarnik hehe .. TRUE !!
 
@r9m :D
$\text{awesome} = -\text{awful}$
I think I started using awesome everytime due to Kung Fu Panda :D :D
 
6:38 PM
 
yessssss
 
Does anyone know about pawel kuczynski though?
 
@Sawarnik: $\text{awesome} = -\text{awful} \implies \text{boring} = 0$
@G.T.R : Tetris, yay!
 
Huy
@Sawarnik: Aren't you like, 14? How can you have played AoE? Did you start gaming at age 6?
 
6:43 PM
@Huy I have .. and I used to liked it.
 
Huy
@Sawarnik: I hope my children won't do that.
 
Well not sure, but I think I was about 8 :/
@Huy True.
 
@G.T.R Isn't that patently obvious?
 
But thankfully I didn't got addicted to gaming.
@Huy Do you think I am obnoxious?
 
r9m
.. didn't get
 
Huy
6:44 PM
@Sawarnik: Why thankfully? Maybe you were to become a professional gamer.
 
@BalarkaSen depends on your standards
 
@Huy Nah ... too risky :P
You played some yu hi oh thing right?
 
Huy
@Sawarnik: Just for fun.
 
But became a payed journalist.
 
Yu Gi Oh! It's like Backugon but with cards instead of balls.
 
Huy
6:46 PM
Well, who would say no to lots of free money.
 
For free?
 
Huy
I didn't pay for any of it.
 
r9m
gets bored and goes back to watching old Sherlock Holmes .. cya
 
Wait a sec @G.T.R. $R[X]$ has a countable basis over $R$. The canonical $\{1, X, X^2, \cdots \}$
 
@Huy I meant you got payed for it!
 
Huy
6:47 PM
@Sawarnik: I know, right?
 
@r9m haha .. i don't have those :( .. so I have to be satisfied be the new one :(
@Huy But few are so lucky [or talented].
 
Huy
@Sawarnik: [or both]
 
Hmm.
 
Is this seriously a math chat room anymore?
 
Huy
@BalarkaSen: Did you listen to Taylor Swift's most recent album yet?
 
6:51 PM
@BalarkaSen Nah!
 
@Huy Who the heck is Taylor Swift?
 
@Huy lol .. best reply!
@BalarkaSen You know. Don't act innocent.
 
Hi everyone
 
Huy
@BalarkaSen: Just some girl. You don't know much about them, do you? :(
 
@Huy Huh?
 
6:51 PM
@barznjy hi
@Huy He does.
 
I don't get it.
 
Huy
Hi, @barznjy.
@Sawarnik: No, he doesn't. ;-)
 
Something tells me I should not google.
 
@Huy Well.
 
I have asked a question about the exponential integral function, but till now I don't received any answer. How I find someone who is specialist in applied mathematics?
here is the link of the question http://math.stackexchange.com/questions/985962/manipulating-constants-inside-the-exponential-integral-function
 
6:55 PM
 
Funny enough, this also gives a closure to the set of square integers, which is pretty nontrivial to prove ;)
 
@Sawarnik Well, you've seen who, haven't you?
 
@DanielFischer I know, but its still odd :/
 
@Sawarnik "Odd" is one of the better things we could say about him.
 
True :D
 
6:59 PM
Apparently Dr. Sonnhard has multiple accounts, but he forgot to use the other one when writing the comment
 
@barznjy: my immediate reaction is that there's not a lot of context to draw people's interest. The lack of clear dfns and intentions moreover makes it unclear what you're asking
 
@BalarkaSen I thought the same thing too.
Yay, I am unignored :D
Ok, I have to go .. byes :D
 
@Semiclassical In fact if the constant part can comes out from the function part, then the manipulation of the exponential integral function becomes much easier
@Semiclassical I know it is a specific question, but this is what I face, I am now struggling in that ..
 
Huy
@barznjy: What exactly do you mean by "seperate the constant term from the function"?
 
@Huy take it out i.e. E_n(x+c) make it E_n(x)
 
Huy
7:08 PM
@barznjy: Are you sure it's possible?
 
@Huy No, I am looking for the possibility of doing that
 
Huy
@barznjy: Good luck.
 
r9m
@Chris'ssis $$\Large \text{YESSS !!!}$$
 
@Huy I rephrased the question as the following;
Is it possible to take out a constant part from the function? If yes, How?
 
@BalarkaSen of course, I wanted to say that $R[X]$, as any space with a countable basis, is not complete (whatever norm you may try)
 
7:14 PM
oh. that is indeed nontrivial to me, not to mention interesting
i am just studying topology in fact
I was going through the starred post and oh my god
LOLOLOL
Oh and here is your Lee, @Jasper : math.stackexchange.com/users/1421/jack-lee
 
@BalarkaSen any topology-related facts you deem interesting to mention ?
 
@G.T.R sure.
 
r9m
@robjohn fantastic answer here !! :D I like !
 
@r9m More or less, they are like Inna (see here an "example")
:D
 
Contour integration is the natural way to proceed, IMO
 
7:28 PM
@BalarkaSen unless I suck at programming, the earlier equation has no solution
 
@G.T.R Very well.
 
r9m
@Chris'ssis hehe :P :D
 
@r9m Many of them take very good positions in large companies here, I mean they are very competent. Some people from other European countries make all kind of statements about us ... but we rule ... (very smart and very nice girls here)
 
r9m
@Chris'ssis good good !! :-) ..
@Chris'ssis smart and nice girl .. !! that's an ultra rare combination in India, very hard to come by ! :P
 
Nobody talks nice with you @Sawarnik
 
7:38 PM
@BalarkaSen Well, not quite.
 
Well, Nick and Jasper are nice with everyone.
 
@r9m don't you like the girls from your country? :-)
 
@Balarka 's really angry wimme, what is the matter? :O
@Chris'ssis Interesting question.
 
@Sawarnik :D
 
@DanielFischer
 
7:39 PM
OK, that reminded me of @Pedro's exercise.
 
Do you know a book with exercises on Complex Analysis? Remmert has few exercises.
 
@BalarkaSen And many more.. :P
 
@BalarkaSen So, what did you deduce negating the thesis?
 
How do you prove that fiber products are universal?
 
@Alyosha Hey :)
 
7:40 PM
Hello.
 
@PedroTamaroff Haven't tried yet. Very pressed with high-school stuffs.
Let's see.
 
@BalarkaSen Really? Is memorizing all the capitals in the world such a bugger?
 
@PedroTamaroff Ahlfors also has few exercises (but most of them are good). Rudin (RCA) has many, Fischer/Lieb has many. Stein/Sharkachi (or however that one is spelled) also seem to have many.
 
@r9m Hmm... I should send you to my class you ll get some nice beating and slapping there :D :D :D
 
@PedroTamaroff No, but memorizing all the names of the damned Vitamins are.
 
r9m
7:41 PM
@Chris'ssis well I have never met anyone form Romania personally .. and pics in internet always turn inadequate (in reality people look much better than how they look on 2d pics :-) .. )
 
And works. And sources. So on and so on.
 
@BalarkaSen You just have the know the goddamn ABC!
 
@Alyosha ?
2
 
Yes?
 
Vitamin A, B, C, D, E, F....
 
7:42 PM
They have names as well..
 
What @Sawarnik said
 
@r9m True. The best way is to visit the country. ;)
 
I rather lazily asked the question so it could be obvious.
 
Pantothenic acid and whatnots
 
@BalarkaSen So, deduce stuff!
 
7:43 PM
@Alyosha Click the question mark
It's a link
 
@BalarkaSen Oh, very good.
 
Hmm @r9m
 
Category theory things have weird names.
 
r9m
@Chris'ssis I always wanted to visit an European Country ! :-) wanted to see first hand how 1st world countries look like in reality ..
 
Fiber products sure seem quite internationally exported. Not sure about universal.
 
7:45 PM
No, you are forgetting about the uniqueness of the export.
 
@r9m I don't think it would be a big problem to visit these countries, or? (well, some of them)
 
@BalarkaSen But you can get them anywhere, no need to get exported.
 
r9m
@Chris'ssis It would be a waste if I were to visit as a tourist ! (best if I got a project/internship some time !! :-) .. but that's hard to get )
 
@Alyosha Hey, how is university ?
 
@r9m Why waste of time? :O O
 
7:47 PM
@G.T.R Hello. It's quite busy. How are you?
 
r9m
@Sawarnik and resource .. I'm not a very rich guy :|
 
I knew a girl that visited India, she was a Christian and went there to spread the gospel, stayed there for 2, 3 months or so ... (I saw some nice pictures from there)
 
@r9m Yes, this definitely.
@Chris'ssis Which place? :)
 
@Sawarnik I don't remember ... (that was like 2 years ago or even more)
 
@Alyosha I'm struggling with probabilities and Python, but otherwise everything's fine
 
7:49 PM
Ok :)
 
@G.T.R We don't have to learn programming, though I am trying C++.
 
@r9m me too .. :)
 
r9m
@Chris'ssis talking about women :P .. I have never seen anyone equaling like her in terms of beauty !! :P
who who who ?? kaun ??
 
@r9m Indeed, it's beautiful ... :-) So, it seems your taste for women is not compatible with the ones from your country. :-)
 
r9m
@Chris'ssis haha !! :P lol
 
7:57 PM
@Studentmath!
 
ohogoaofdasod
@Balarka!
Take a look a sec
if I take $c=1$ it would be $-\infty$ right?!?
 
W|A takes years to open up for me.
Can't you latex or something?
 
hi
do you like algebraic topology?
