that pic is a lot better as your gravatar.

Ed Gorcenski

Guten tag

MeAndMath

@EdGorcenski wie geht es dir?

Ed Gorcenski

Not bad, pizza makes the world better.

MeAndMath

@EdGorcenski ja,ja,for sure!

Nimza

Help me please, is there a name for such characteristic of region?

user19161

5:11 PM

@MeAndMath They misspelled "pericardium"!

Mariano Suárez-Alvarez

a name for what?

Jayesh Badwaik

directed sets and lattices are the same thing right?

Nimza

@MarianoSuárez-Alvarez for classes of equivalence of connected components. They are defined as a posted above

MeAndMath

@WillHunting jesus...that's ugly.

Mariano Suárez-Alvarez

hm?

user19161

5:13 PM

@Nimza Do you just mean connected components themselves?

Nimza

@WillHunting no, they classes. This pic is no so representative

Mariano Suárez-Alvarez

as posted above where?

user19161

@MarianoSuárez-Alvarez Do you see the picture above?

Mariano Suárez-Alvarez

yes

user19161

Maybe you need to refresh the browser.

Mariano Suárez-Alvarez

5:14 PM

there are numbers in it

but no definition of anything afaics :-)

Zhen Lin

Reopen request

Nimza

@WillHunting so if we place the same curve near this one the numbers will be copied

MeAndMath

@ZhenLin why?should be edited before.

user19161

@Nimza I am afraid I do not understand what you are saying since I don't know anything about this field.

Mariano Suárez-Alvarez

Nimza, i have yet no idea what you are asking... :-/

Zhen Lin

5:16 PM

@MeAndMath Because the question has been edited to a more reasonable state.

Nimza

oh, so bad.... I don't know anything about this field too

Gustavo Bandeira

@WillHunting !!!

@WillHunting You disapeared.

MeAndMath

@ZhenLin yes,it's kind better now.

user19161

@GustavoBandeira I am always disappearing; I am a magician!

MeAndMath

@GustavoBandeira Gustavo!!!

user19161

5:17 PM

@Nimza Yeah, I am not sure what you want to describe from start to end.

Gustavo Bandeira

@WillHunting "For my next trick, I'll make you disappear" - Shaco from the League of LEgends

@MeAndMath Yo!

I dreamed I had classes about Chebyshev Polynomials.

MeAndMath

@GustavoBandeira e aí?

Nimza

@WillHunting I'll try again. I have a curve. Self-overlays of curve are prohibited. If almost every line passing through point $P$ intersects curve in $2k$ points then P has characteristic $k$...

Gustavo Bandeira

@MeAndMath Tô bão, e tu?

MeAndMath

@GustavoBandeira I live dreaming about lectures .

@GustavoBandeira bem,também.

Gustavo Bandeira

5:19 PM

@MeAndMath Weirdness...

=D

@WillHunting You left me worried, dude...

Nimza

@WillHunting no, it's bad too... Intersects line from one side of $P$ exactly $k$ times or I don't know how to formalize it

Dan the Man

How do I solve $x^2 + x = 1728$?

MeAndMath

@GustavoBandeira it's rare not to dream about math.

user19161

@GustavoBandeira You should worry about me, but not because of that!

Gustavo Bandeira

@MeAndMath This is the second dream I have about it, in the first dream, I stole a topology book.

MeAndMath

5:21 PM

@GustavoBandeira you stole it?

Ed Gorcenski

@DantheMan Use the quadratic equation

Gustavo Bandeira

@MeAndMath I dreamed I stole it.

Ed Gorcenski

$x^2+x = 1728 \Longrightarrow x^2+x-1728 = 0$

user19161

@Nimza This is TOO complicated. :)

Mariano Suárez-Alvarez

@Nimza, I don;t know if the number has a name —people are usually interested only in its oddness/evenness: http://en.wikipedia.org/wiki/Even-odd_rule
If you want to compute it (for polygons) the code in that page is easily modifiable to do so

Dan the Man

5:21 PM

@EdGorcenski k

Gustavo Bandeira

@MeAndMath O livro que eu tô lendo éde 1989 - exatamente o ano que eu nasci!

Nimza

@WillHunting yeah, sorry :)

MeAndMath

@GustavoBandeira I usually realize I'm dreaming because of math.illogical things.

Gustavo Bandeira

Rola aquela conexão idiota: O livro foi feito pra mim! <3

Nimza

@MarianoSuárez-Alvarez yeah, I exactly want generalization of this thing!

MeAndMath

5:22 PM

@GustavoBandeira que bonitinho!

Ed Gorcenski

I once derived the adiabatic ascent rate equation for a vented gas balloon in my dream. I was being chased by monkeys at the time.

MeAndMath

@EdGorcenski that's a good dream.

Ed Gorcenski

It was very convenient, as it happened to be a homework problem. I did not receive bonus points for doing it in my sleep, or for doing it whilst being chased by monkeys.

user19161

Talking about dreams, I have had many dreams in which I was flying without wings.

Nimza

@MarianoSuárez-Alvarez thank you for a link. I'll try with it

MeAndMath

5:24 PM

that's good,too.

Gustavo Bandeira

@EdGorcenski You were in Amazonia then!

@WillHunting Dragon Ball Z!

MeAndMath

@GustavoBandeira I was saying before,i am dreaming with MSE!

Ed Gorcenski

The monkeys were actually in Troy, NY. I do not know why they were there, just that they were chasing me.

user19161

@MeAndMath Maybe about someone on MSE? Hehe.

MeAndMath

the weird is i dreamt with peter and jonas...

and the chat itself...

Gustavo Bandeira

5:25 PM

@MeAndMath Dreaming with two trolls...

@N3buchadnezzar Are you the guy from elipses and booties?

MeAndMath

talking about linear algebra.

user19161

@GustavoBandeira They are lefties like me.

Gustavo Bandeira

Do you know something I'm VERY curious?

N3buchadnezzar

@GustavoBandeira ?

Gustavo Bandeira

Non--Linear stuff

MeAndMath

5:26 PM

@GustavoBandeira why?

Gustavo Bandeira

amazon.com/COMPLEXITY-EMERGING-SCIENCE-ORDER-CHAOS/dp/…

I've read this book.

It tells somethings about non linear stuff.

MeAndMath

Can I make a question???

Gustavo Bandeira

To me? Always.

Peter Tamaroff

"-70 User was removed"

FUCK YOU WORLD.

MeAndMath

sounds nice.well,what's the difference between chaotic and random?

Gustavo Bandeira

5:30 PM

@PeterTamaroff Dude...

user19161

@GustavoBandeira Ah, I dislike these "popular science" books!

Jayesh Badwaik

@PeterTamaroff Well that escalated quickly.

user19161

@PeterTamaroff I lost 30!

Gustavo Bandeira

@PeterTamaroff I have an outspoken badge, dude....

user19161

@PeterTamaroff Very dramatic!

MeAndMath

5:30 PM

@WillHunting just for fun.

Gustavo Bandeira

@PeterTamaroff It's a shame that you're coming to tell me that you lost rep... I just got an outspoken badge, dude...

Jayesh Badwaik

@MeAndMath The chaos is a specific type of behavior, where the state of a system in future is highly sensistive to initial state

user19161

@MeAndMath Of course I know, I have known Pedro for 9000 years!

Gustavo Bandeira

@MeAndMath It seems that the chaos has a pattern.

It's VERY difficult to describe, but it has one. While random doesn't have.

MeAndMath

@JayeshBadwaik oh...

Gustavo Bandeira

5:32 PM

I guess it's this, but not much basis for it.

@WillHunting I like them because it's the only thing I can read now.

Anyway, the author suggests some nice books.

user19161

@GustavoBandeira No, no. You need to get the basics first. :-)

Peter Tamaroff

@JayeshBadwaik I went to a meeting for alumni of the faculty of maths at my uni. I met some girl and I asked "Well, why are you interested in math" She: "Because it discovers/finds the harmony of chaos"

Gustavo Bandeira

@WillHunting It's the 10th time you tell this to me.... ¬¬

user19161

@GustavoBandeira Yes, because I feel you are treading the wrong way...

MeAndMath

@GustavoBandeira you should listen to him.

Gustavo Bandeira

5:34 PM

No, I understand that I can read nothing without a math degree.

MeAndMath

@PeterTamaroff and you?

Gustavo Bandeira

@MeAndMath I'm listening, but he repeats it everyday.

MeAndMath

'cause it's important.

user19161

@GustavoBandeira Not really, you just have to learn the topics in a more traditional order!

Gustavo Bandeira

@WillHunting When I try to read such complicated things, I feel me lost as shit.

Ed Gorcenski

5:35 PM

That should be motivation to learn

Jayesh Badwaik

@PeterTamaroff Hmm.

MeAndMath

@GustavoBandeira yeah,that's bad...

user19161

@GustavoBandeira One cannot study algebraic geometry if one cannot solve a quadratic equation, for example.

Gustavo Bandeira

I am able to learn

Peter Tamaroff

@JayeshBadwaik I could only think to myself, "Oh! How poetic. Maybe you wanna sign up for the Liberal Arts faculty."

Gustavo Bandeira

5:36 PM

@WillHunting I know.

user19161

@GustavoBandeira Are you going to take a degree in math by the way?

MeAndMath

Why people study math?

Gustavo Bandeira

@WillHunting Yes.

MeAndMath

'cause is fuckin' awesome!

Gustavo Bandeira

@MeAndMath People is stoned....

XD

Jayesh Badwaik

5:37 PM

@MeAndMath Yup, it is!

user19161

@GustavoBandeira OK, good.

Jayesh Badwaik

@PeterTamaroff I had a interview for a distinguished scholar program, and there one of the questions asked was "Why do you want to go into mathematics?"

and I could say nothing more that "I like it and think it is really cool." :-/

Peter Tamaroff

@JayeshBadwaik What did you answer¿

Jayesh Badwaik

I was damn nervous at that time.

user19161

@JayeshBadwaik I am quite sceptical about programs with such names. :)

Gustavo Bandeira

5:39 PM

My mom just said that excessive study will let me nuts. xD

Peter Tamaroff

@JayeshBadwaik You had a chance to be famous... aaaaaaaaaand its gone.

MeAndMath

If you have to think why you study math, then you don't have to study it.

user19161

@GustavoBandeira No, not really. But I know what can make one nuts though...

Jayesh Badwaik

@WillHunting It was not the actual name. The actual name is in hindi. It is translated to "young Scientist Encouragement Program"

@PeterTamaroff Naah, it did not make anyone famous. 70% of people do not even know of the program.

MeAndMath

@GustavoBandeira I was born nuts!

user19161

5:40 PM

@JayeshBadwaik Ah, I guess I am always sceptical because where I come from there are many programs with fanciful names but actually they are nothing.

user19161

@MeAndMath Really? Hmm, you should not be happy that you are nuts. If you are really nuts like me, it is a very sad thing...

Jayesh Badwaik

@WillHunting KVPY as we called it is a really good program. We have a few but really good programs here for students.

MeAndMath

@WillHunting that is what makes me happy about myself.

user19161

@JayeshBadwaik I have seen a number of books and programs from your country and people. I admire the Indian mathematicians.

Gustavo Bandeira

I don't care bout education! math is my motivation!

Jayesh Badwaik

5:43 PM

@WillHunting Yeah, they are good. :-)

Gustavo Bandeira

@WillHunting You're not going to tell me that Justin Bieber lets on nuts, are you?

Jayesh Badwaik

Quiet less in number compared to the full population, but whatever is there is good stuff.

MeAndMath

@GustavoBandeira isso dá um grito de guerra,hein!

user19161

@JayeshBadwaik I am very sick of universities that spend money on building taller and taller buildings but do little to improve the curriculum, I shan't name them.

Jayesh Badwaik

@WillHunting Can I have a guess?

user19161

5:45 PM

@JayeshBadwaik Shh...

Gustavo Bandeira

@MeAndMath Né?!

Jayesh Badwaik

@WillHunting Okay!

Gustavo Bandeira

@MeAndMath Tu tem celular TIM?

(Mesmo que tenha, duvido que tu me dê) XD

user19161

@JayeshBadwaik In a way, many things in this world are superficial like that.

Jayesh Badwaik

@WillHunting Yeah bro, completely agree.

Gustavo Bandeira

5:46 PM

You don't like, you know, "sharing information".

MeAndMath

@GustavoBandeira não.mas você tem razão...

ddd é caro...

user19161

@JayeshBadwaik Those university rankings and international tests mean nothing to me.

Gustavo Bandeira

@MeAndMath Eu tenho TIM beta.

John Junior

hi @m.k.

MeAndMath

@GustavoBandeira what does that mean?

user19161

5:48 PM

@JohnJunior Hi John!

Jayesh Badwaik

@WillHunting Hmm. I have had not the oppurtunity to either test or refute them. But I have had people telling me the same thing that it does not really matter.

John Junior

@WillHunting Hi Will!

Jayesh Badwaik

@WillHunting and btw your salutation is wrong. It is more like follwing
@JohnJunior Hi Junior!!

user19161

@JohnJunior LOL, I just realized we star in my two favourite movies, Good Will Hunting and A Beautiful Mind!

Gustavo Bandeira

@MeAndMath Tim beta é uma promoção da TIM - Eu posso ligar/passar SMS/ por uma quantia fixa. Eu pago ~30 centavos se eu fizer uma ligação no dia. Depois disso, eu posso fazer ligação o resto do dia pagando apenas esse dinheiro

John Junior

5:49 PM

@JayeshBadwaik Hi

MeAndMath

@GustavoBandeira ahh...

Gustavo Bandeira

@MeAndMath May tu num deve ser doida feito eu não. xD

Da última vez, eu conheci uma mina no Rio, a gente namorou um tempo e ela me sacaneou!

Jayesh Badwaik

@JohnJunior I liked how you handled guiding Dan The Man earlier. I learned something from it. Thanks.

Gustavo Bandeira

Yay!

Da última vez, eu conheci uma mina no Rio, a gente namorou um tempo e ela me sacaneou!

Yay!

MeAndMath

@GustavoBandeira e?

John Junior

5:51 PM

@JayeshBadwaik Thanks :)

Gustavo Bandeira

@MeAndMath É "e" ou "é"?

@MeAndMath Num significa que eu quero o mesmo com você, hein?!

user19161

@JayeshBadwaik How did he handle it? With his hands?

MeAndMath

@GustavoBandeira I realized.once you told you are in a relationship.

Gustavo Bandeira

@MeAndMath E a resposta a minha pergunta? Continua sem gostar de "share information"?

Jayesh Badwaik

@WillHunting The method of giving hints. I was giving him answers too easily. Giving him the fish instead of teaching how to fish, you can say.

MeAndMath

5:55 PM

@GustavoBandeira I barely know you...I wouldn't give my number ...

Dan the Man

@JayeshBadwaik Hahahahahahahahahaha... Talking about me, eh?

user19161

@JayeshBadwaik Well, the best method is: learn to fish yourself. :-)

Gustavo Bandeira

@MeAndMath Haha

John Junior

What does a fish know of the water he swims in all his life?

Gustavo Bandeira

@MeAndMath Isso que dá não gostar de estatística.

MeAndMath

5:57 PM

@GustavoBandeira are you laughing?

user19161

It is good to ask questions, but I think one needs to think more before asking others.

MeAndMath

@GustavoBandeira por quê?

Jayesh Badwaik

@DantheMan Yup, I used to teach my brother and other high school kids, while my brother did not have much problem since I could spend a lot of time on him, but I was not so successful with other kids.

user19161

@JohnJunior Er, I dunno.

Gustavo Bandeira

@MeAndMath Tecnicamente - a chance de eu ser um maluco pervertido do capeta é a mesma chance que tu enfrenta ao sair na rua.

MeAndMath

5:58 PM

@GustavoBandeira melhor não ,né.

Gustavo Bandeira

Eu vejo uma equivalência: Se tens medo d'eu, terás medo de sair de casa,.

Dan the Man

@JayeshBadwaik Ah cool! Are you from India?

Jayesh Badwaik

@DantheMan Yup.

MeAndMath

@GustavoBandeira I don't like talk in the phone.

Gustavo Bandeira

@MeAndMath Estranha. xD

user19161

5:59 PM

@JayeshBadwaik I watched Slumdog Millionaire.

Dan the Man

@JayeshBadwaik Sweet. I'd like to go there some day. And I have to study about Indian history, right now. Interesting stuff.

MeAndMath

@GustavoBandeira me dão vários adjetivos aqui...

user19161

@DantheMan Is it schoolwork?

Dan the Man

@WillHunting Yeah.

Jayesh Badwaik

@WillHunting It is not that good a movie fact-wise.

Gustavo Bandeira

6:00 PM

@MeAndMath Relaxa. Num to dizendo que tu é diferente não, a gente tá no mesmo barco. Eu já conto com umas acusações de bruxaria, psicopatia e esquisofrênia.

user19161

@JayeshBadwaik No movies are, except docus.

Gustavo Bandeira

Vô dar uma saída agora - vô na casa da muié. =)

Cya guys.

MeAndMath

vai lá!

user19161

@MeAndMath What language is this?

MeAndMath

@GustavoBandeira eu sou meio tímida,mesmo...não leve pro lado pessoal.

@WillHunting portuguese.

Jayesh Badwaik

6:01 PM

@WillHunting Portuguese

user19161

@MeAndMath Ah, do Carmo!

MeAndMath

@WillHunting youo already said that.

user19161

@JayeshBadwaik I watched it a few times.

Jayesh Badwaik

@WillHunting Okay. I have watched it only once. I don't generally like to watch movies.

MeAndMath

portuguese $\neq$ spanish

user19161

6:04 PM

Yes, one starts with p, the other s.

MeAndMath

@WillHunting NOOOOOOOO!!!!!!!!!!!!!

Dan the Man

It's completely different.

user19161

@MeAndMath Well, they call me Captain Obvious in the other room.

MeAndMath

PORTUGUESE IS MUCH BETTER!

Dan the Man

NOOOOOOO. ESPAÑOL ES MEJOR!

MeAndMath

6:06 PM

português é a língua dos anjos!

lingua franca

@JayeshBadwaik what?

A lingua franca (or working language, bridge language, vehicular language) is a language systematically used to make communication possible between people not sharing a mother tongue, in particular when it is a third language, distinct from both mother tongues. Characteristics "Lingua franca" is a functionally defined term, independent of the linguistic history or structure of the language: though pidgins and creoles often function as lingua francas, many such languages are neither pidgins nor creoles. Whereas a vernacular language is used as a native language in a single speaker communi...

user19161

@JayeshBadwaik English is the LF!

MeAndMath

@WillHunting yes.

Jayesh Badwaik

6:10 PM

@WillHunting My point exactly. While all of you were sparring on other languages, I said "english > portuguese, spanish"

MeAndMath

in terms of comunication

is a simp´le language.funny.

Jayesh Badwaik

@MeAndMath ?

MeAndMath

@JayeshBadwaik english is better than portuguese and spanish to be simple.easy to learn.

John Junior

math is a language

Jayesh Badwaik

@MeAndMath Hmm, also, as far as I know, it is easier to modify the language "locally" to suit your needs, that is your changes do not affect the use of language by others and hence are forward/backward compatible.

This in my opinion makes it more powerful than other languages.

MeAndMath

6:14 PM

you have a point.

John Junior

@WillHunting Did you ever decide on the meaning of the peom your friend wrote?

user19161

@JohnJunior Nope, I never asked him. But I think it is what we discussed. One cannot proceed until he has understood things. "One cannot leave till he has arrived"

user19161

@JohnJunior It was just a quote, not something he wrote. But he did write over 200 poems.

Peter Tamaroff

@JonasTeuwen d24w6bsrhbeh9d.cloudfront.net/photo/5325140_700b.jpg

John Senior

This might be interesting - if it pans out OK

user19161

6:24 PM

@JohnSenior Wow wow wow.

John Senior

@WillHunting exactly!

user19161

@JohnSenior Maybe one day we will read that John Senior has patched the originally incorrect proof!

John Senior

I have just downloaded the 4 papers - but think I might not get past the first paragraph of each :)

Jayesh Badwaik

@JohnSenior Oh dear god. 500 pages proof!!

John Senior

@WillHunting ROFLMAO

user19161

6:26 PM

I am more interested in the RH.

John Senior

" ... semi-graphs of anabelioids, Frobenioids, the Etale theta function, and log-shells ..." - looks like my chances are zero :)

user19161

@JohnSenior Like they say, from zero to hero!

robjohn

@PeterTamaroff You got off easy :-p

user19161

@robjohn I only lost 30!

Peter Tamaroff

@robjohn High rep user problems: robjohn

user19161

6:28 PM

But then I have so little to begin with.

user19161

@PeterTamaroff Has your algebra class ended?

Peter Tamaroff

@WillHunting like 2 and a half hours ago,

it lasted 3 hs, though

plus 3 hs of chemistry before that, in a row

user19161

@PeterTamaroff Ah, what did you do in the class?

Peter Tamaroff

MOTHEROFGOD

@WillHunting I read Jona's notes about Bernstein polynomials. and LAWLLED.

user19161

@PeterTamaroff OMG!

Peter Tamaroff

6:31 PM

@WillHunting wut?

user19161

@PeterTamaroff Nothing, I just like to exclaim at everything.

robjohn

has mathjax stopped working on the site for anyone else?

Jayesh Badwaik

main site you say?

user19161

Hehe, I usually don't use it.

Jayesh Badwaik

$\neq$

chat works for me

David Hoffman

6:32 PM

Hi, does anyone here know a lot about ellipses?

John Senior

@JayeshBadwaik Main site? - I thought this was it :)

user19161

@DavidHoffman You should just ask the question directly.

robjohn

It works here, but on the main site, things show up as unrendered

Jayesh Badwaik

@robjohn it works for me there too.

John Junior

@robjohn Yes, mathjax stopped working on the site for me.

John Senior

6:33 PM

@robjohn seems fine here in UK

David Hoffman

How would you calculate minimum distance between two arbitrary ellipses in 2D?

user19161

@robjohn Are you on Chrome?

robjohn

I'm restarting my browser... bbl

Jayesh Badwaik

@robjohn Just in case for such things, I have hosted my own copy of mathjax on an http server on laptop.

David Hoffman

@WillHunting How would you calculate minimum distance between two arbitrary ellipses in 2D?

user19161

6:36 PM

@DavidHoffman Hmm, why not post on the main site? Sounds interesting.

John Senior

sheesh - I think it might be months before anyone decides if Shinichi Mochizuki's proof is valid :(

robjohn

Still bad on the main site for me.

user19161

@JohnSenior Good things take long.

Jayesh Badwaik

@JohnSenior Probably next year.

John Senior

@JayeshBadwaik Yep

user19161

6:38 PM

@robjohn Firefox tends to work better than Chrome.

Jayesh Badwaik

@WillHunting but seriously, 500 pages? considering that all the pages must be highly technical it seems like he has written two books atleast :-)

robjohn

@WillHunting I am on Firefox

Peter Tamaroff

@robjohn I downloaded Firefox for anrdoid! Curious it is that I couldn't get Chrome installed....

user19161

@PeterTamaroff Ah, but there is no flash on android right?

Peter Tamaroff

@WillHunting Flash?

user19161

6:40 PM

@PeterTamaroff Adobe Flash, I dunno.

Jayesh Badwaik

@WillHunting There is! On my android there is. But I don't use it anyway.

robjohn

I am updating my FF

user19161

@robjohn It is 15 now.

Peter Tamaroff

@WillHunting Yes. It has Java, too, I think.,

robjohn

I have 14.0.1, I imagine I will lose connection while I update. BBL

Peter Tamaroff

6:42 PM

I'll now proceed to watch the feature film "The Avengers".

Jayesh Badwaik

@robjohn http://math.stackexchange.com/questions/193716/proving-that-fx-is-not-olog-fx
oh just saw you will be gone.

user19161

@PeterTamaroff Very few sites use Java these days it seems.

Peter Tamaroff

@WillHunting math.SE does!!!

robjohn

Nope, I am on 15.0.1 and It still doesn't render on the main page.

John Junior

That was fast :)

Jayesh Badwaik

6:43 PM

@PeterTamaroff @WillHunting probably meant Java VM. Math.SE uses javascript and probably uses a lot of java programs internally.

user19161

@robjohn It renders properly here. I think it might be your internet connection.

Jayesh Badwaik

@robjohn you might not be getting mathjax cdn thing.

anon

It isn't rendering in my chrome either.

user19161

@JayeshBadwaik I never understood the diff between the two javas.

robjohn

@WillHunting It renders here for me and locally on my local pages, but not on the main site.

user19161

6:45 PM

@robjohn Oh, maybe it's too loaded now somehow.

Peter Tamaroff

@JayeshBadwaik What is Java VM?

Jayesh Badwaik

@robjohn use you chatjax bookmark for the main site? Does that do anything?

robjohn

If you look at this page, does the MathJax look okay?

@JayeshBadwaik I tried that, and since MathJax is defined there, it doesn't install ChatJax, but uses what is there.

Jayesh Badwaik

@WillHunting @PeterTamaroff There are two different languages. Java and Javascript. The similarity starts with their names and ends with a little bit os similarity in syntax

user19161

@robjohn Yes, takes a while though.

Jayesh Badwaik

6:47 PM

@robjohn I am on firefox 14.0.1 and it renders correctly for me.

user19161

I am on 15.0 on Fedora.

Peter Tamaroff

@robjohn Chrome ain't wuuurrking either here

user19161

@PeterTamaroff Chrome has many problems with MSE as you can see on meta.

Jayesh Badwaik

@PeterTamaroff The american mathjax cdn server must have crashed.

robjohn

I can't even resolve cdn.mathjax.org

user19161

6:50 PM

@robjohn That must be the problem then.

robjohn

This is weird, since I can use MathJax elsewhere.

Peter Tamaroff

Invalid URL

The requested URL "/", is invalid.
Reference #9.cf985292.1347303015.b3938ea9

Jayesh Badwaik

@robjohn try this.
https://c328740.ssl.cf1.rackcdn.com/mathjax/latest/MathJax.js

robjohn

@JayeshBadwaik I can see that page.

Jayesh Badwaik

Okay, so that is the main hosting server for MathJaX and you can see that, so there must be some problem on MSE MathJax link then.

user19161

6:51 PM

It's a sign that @robjohn must take a break from the site!

Jayesh Badwaik

@robjohn does the ping on this IP work. 125.252.225.142

This is the IP hosting cdn.mathjax.org i got from dig.

robjohn

The main site is getting its MathJax from http://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS_HTML
