Mathematics - 2012-09-17 (page 2 of 3)

@GustavoBandeira Hmm. while speaking "Bengali", a language of Bangladesh and West Bengal (a state in India), they interchange the pronunciation of "b" and "v". Major headache.

Gustavo Bandeira

Yep

Jayesh Badwaik

2:16 PM

So what we write as "Vinay", they read as "Binay" and when we write as "Binay" they read as "Vinay". :P :P And whenever they do so, I ask them "why?"

Gustavo Bandeira

It reminds me of spanish.

Viño - You read the V as B.

Actually, if you hear one spanish speaker, you're gonna notice they speak it as if they were mixed. It's not a V or B, it's a kind of VB - at the same time.

Peter Tamaroff

Fuck you that why =)

*That's

Jayesh Badwaik

@WillHunting We can say that an function algebra is just a ring but without the identity and the inverse clause. Am I correct?

anon

@GustavoBandeira That's what I told myself 7 years ago.

Parth Kohli

Very observant, @Will

Gustavo Bandeira

2:25 PM

@anon Well, I wrote a music which is called Utopiocrata - Utopiocrat, someone who lives in utopy.

Parth Kohli

Wait, I still see the Einstein.

anon

sounds cool. not sure why it's called utopia though.

Different areas where the gravatar show up may take slightly different times for the change to propogate.

Parth Kohli

I see, what do you see, Anon?

robjohn

@ParthKohli Have you signed out of Gravatar.com? That seems to start the propagation of the gravatars.

@PeterTamaroff Play nice...

Parth Kohli

I, to experiment, removed my Gravatar an hour back.

What exactly do you mean by "propogation," @robjohn?

Gustavo Bandeira

2:31 PM

@robjohn I said something similar sometime ago, you said me ahem. I thought: Well, now I'm gonna die.

Such a state of panic.

robjohn

3. To spread from person to person; to extend the knowledge
of; to originate and spread; to carry from place to place;
to disseminate; as, to propagate a story or report; to
propagate the Christian religion.
[1913 Webster]

Parth Kohli

Well, what do you mean by that word here?

anon

On the net, certain things like gravatars have existences in multiple places. When information propogates, it goes from place to place via automated processes designed to keep everything up-to-date.

robjohn

@ParthKohli the spreading of the icon from place to place.

Parth Kohli

Oh, that? Yes.

Gustavo Bandeira

2:34 PM

@ParthKohli Also, what's the your main account on SE?

robjohn

@GustavoBandeira I'd guess math.SE from their profile...

Parth Kohli

You can go to my profile, and click on "parent account," but for lazy people, my main account is Math.SE.

Gustavo Bandeira

I log in with facebook acc, but my main acc is from Mathematica.SE and my first login there was with google acc.

I remember of trying to change my pic on gravatar and it simply didn't change, someday I switched my google acc pic and it was done.

@robjohn Nope, it's not this. You can login with a SE acc or with a google acc or with facebook, etc.

robjohn

@GustavoBandeira I was saying that looking at Parth's profile, they have the most rep and badges on math.SE, so I would guess that that was the main account.

Parth Kohli

Yes, that is.

Let's check out fast Gravatar is... and the timer starts NOW!

Gustavo Bandeira

2:39 PM

@robjohn I know, but I was refeering to the login account.

robjohn

@ParthKohli You have two logins. Did you give the right one to gravatar.com?

Parth Kohli

Two logins? I have only one I know of.

robjohn

@ParthKohli I think that SE only looks at the one for the email address you've registered with.

@ParthKohli Look in your profile under "my logins"

Parth Kohli

This is weird: I have a different picture in my profile, and different picture on this chat.

If you hover your mouse over my name, you'd see that I have a different picture(the one I uploaded to Gravatar).

robjohn

@ParthKohli the two sites (chat and math) refresh at different times.

@ParthKohli You may need to refresh your browser.

Parth Kohli

2:44 PM

Actually, my profile on Chat Exchange has the new picture as well.

This is the first time I refreshed and it worked. Thank you @robjohn!

robjohn

@ParthKohli Yeah, your browser caches these icons and sometimes needs a kick to know to look for an update.

Parth Kohli

@robjohn actually, I had been refreshing it again and again.

robjohn

@ParthKohli The gravatar just got here then.

Matt

@robjohn I think I ken lee without him.

robjohn

@ParthKohli your gravatar on your chat account should be the same as that on the chat account's parent account

@Matt That is funny!

Matt

2:54 PM

: )

Gustavo Bandeira

@Matt She was singing about a brother of Jet Li.

Matt

Who knows : )

Gustavo Bandeira

I wrote an e-mail to Jonas, a warm "get back to the chat as soon as you can".

It's the second I do such an altruistic gesture, the first one got me locked until now. One classmate was sick, I printed a card: "I hope you get good soon" - he acted coldly. I was like: What happened?!

I was like 8 years old.

robjohn

3:29 PM

I hope that this comment does not spark a flame war.

anon

I don't feel any heat emanating from that.

robjohn

@anon I tried to be as cool as possible, but I have seen flames rise from the most stonelike places.

Gustavo Bandeira

4:19 PM

SE's facebook app posted my question. :) :) :)

4

Q: What are the dangers of visual exposition of mathematics?

I've heard several times (such as this one) that it's dangerous to learn/prove/teach mathematics through images. I've also read somewhere that showing mathematics through images helps one's intuition because we understand better through images, due to our long date use of the vision sense. I can...

John Junior

4:53 PM

I need this game :-D

John Junior

5:03 PM

@robjohn This looks like a "we didn't start the flame war" kind of situation ;-)

John Junior

5:26 PM

hi @MarianoSuárez-Alvarez

Could you please look into why Jonas Tweuwen's account was "automatically suspended"?

Mariano Suárez-Alvarez

/me looks

John Junior

/many thanks :)

Mariano Suárez-Alvarez

he is not suspended in the main site

where did he get this notification?

John Junior

@MarianoSuárez-Alvarez The 7 star message on the right panel ---->

Mariano Suárez-Alvarez

but in what way does this suspension manifest itself? can he log into the main site?

there is no record in his user sheet of being suspended

John Junior

5:37 PM

That is all I know :(

Mariano Suárez-Alvarez

ok. I 'll write to him

thanks!

John Junior

np

Gustavo Bandeira

5:59 PM

@WillHunting I sent him the e-mail.

user19161

@JohnJunior My guess is that certain words trigger an autoflag. Maybe I should experiment now.

user19161

The following is a test.

user19161

Shut up.

user19161

Gay.

user19161

OK, I think chances are someone flagged him and many people agreed on the flag so when it reaches a certain number of agreements suspension from chat takes place automatically.

user19161

6:03 PM

But it is only for half an hour from chat in most cases and the main accounts can still be used.

user19161

Hey flaggers, have the guts to own up when you flag someone. Jonas is a good guy.

user19161

If you don't like something someone says, you can always tell the person directly. It shows me your character when you do such things.

user19161

Hello @meandmath!

MeAndMath

@WillHunting Hi willie B!

user19161

@anon Soon, you will solve one.

MeAndMath

6:12 PM

@GustavoBandeira hi hi!!

Gustavo Bandeira

@MeAndMath Hello. =)

MeAndMath

@GustavoBandeira in my uni there was several speeches about the millenium problems....DAMN IT !!!IT'S FUCKING HARD!!!!

Gustavo Bandeira

@MeAndMath Yep. Where are these problems enlisted? Do you know?

MeAndMath

@GustavoBandeira facebook.com/…

Gustavo Bandeira

Wasn't Poincaré's conjecture solved by Grigory Perelmann?

MeAndMath

6:18 PM

@GustavoBandeira yeah...

parece que tem estudo ao redor ainda

não sei..

Gustavo Bandeira

Actually, I did all the work while Perelmann was eating donuts.

MeAndMath

mas honestly,these speeches wasn't elucidative...

@GustavoBandeira rsrsrrsrsrs

Gustavo Bandeira

@MeAndMath Mathematics Elucidative?!?! lol

MeAndMath

@GustavoBandeira um professor me disse que essas palestras são estúpidas porque não mostram o que um matemático faz...um matemático não fica trabalhando nisso....

Gustavo Bandeira

Como assim?

MeAndMath

6:22 PM

ah,um matemático não vai trabalhar dia-a-dia na hipótese de yang mills....é assim:você é especialista nm assunto e calha de você estar próximo doproblema e v~e que TALVEZ valha a pena trabalhar no problema...

foi o que o wiles fez

Gustavo Bandeira

Depois que eu vi a história do cara dos quaterniões, eu meio que fiquei pensando que cê olha o problema e dá um flash na mente.

MeAndMath

mesmo assim a prova tinha um ERRO que ele demorou quase 2 anos pra arrumar mais a ajuda de um amigo...

@GustavoBandeira né assim não...é muito trabalho

um pouco de insight e muito suor..

esse prof me diz isso:esses negócio de ter um insight mágico é extremamente raro e ilusão...

Gustavo Bandeira

Sim.

O que eu quiz dizer foi: Insight depois de 300 anos lendo coisa.

MeAndMath

@GustavoBandeira vai saber...

Gustavo Bandeira

Porque a coisa do insight do nada, é ilusão sim.

MeAndMath

6:25 PM

@GustavoBandeira sim,sim

Gustavo Bandeira

Eu li um texto do Terrance Tao - acho que é esse o nome dele.

MeAndMath

@GustavoBandeira que tem?

Gustavo Bandeira

Ele falava isso.

user19161

The return of the non-English strikes again.

MeAndMath

oh will...

@WillHunting I wanna make you a proposal

user19161

6:28 PM

@MeAndMath Yes?

Gustavo Bandeira

@MeAndMath Marília M Janizelli?

MeAndMath

@WillHunting When I write my comment I will put in parentheses a W which means that I am not sure if what I'm writing is correct and I want youo to correct.
if I don't put (W) then you warn me :there's something wrong,then I will try to correct it myself.Then it is more interesting and fun!what you think?

@GustavoBandeira quê?

Gustavo Bandeira

@MeAndMath É você?

MeAndMath

@GustavoBandeira é...por quê?

Gustavo Bandeira

Haha.

Ed Gorcenski

6:32 PM

Afternoon

MeAndMath

@GustavoBandeira que foi?

will?

@EdGorcenski afternoon

Ed Gorcenski

Is it me, or is this answer just straight up incorrect

Gustavo Bandeira

Cê tinha me falado o primeiro nome, agora me mostrou o evento. Eu fui stalkear pra ver se tinha alguma marília, ache esse nome. Quando abri o perfil, parecia MUITO similar a projeção que eu tenho de ti.

Ed Gorcenski

-1

A: Fractional calculus in complex analysis

Its easy. Just do the integral and then just replace your real x with complex z.

user19161

@MeAndMath Hmm OK, if I remember. Anyway that took me a while to understand.

user19161

6:34 PM

@EdGorcenski Hmm, don't even know what that means.

MeAndMath

@WillHunting EX: I am Marylin (W)

@GustavoBandeira mas nem tem foto minha...

Gustavo Bandeira

@MeAndMath What's the problem?

MeAndMath

@GustavoBandeira well....what image you had about me?

Gustavo Bandeira

@MeAndMath Not image: Projection.

With this, I mean how your personality should be. I know nothing about your form.

MeAndMath

@GustavoBandeira hmmm

Gustavo Bandeira

6:38 PM

@MeAndMath It's exactly as the projection I had of you. =)

I've read the posts now.

user19161

@GustavoBandeira Erm...

MeAndMath

@GustavoBandeira and?

Gustavo Bandeira

And...

BANANAS!

MeAndMath

@GustavoBandeira yes and

@GustavoBandeira what does that mean?

Gustavo Bandeira

MeAndMath

6:45 PM

come on

Gustavo Bandeira

THIS THAT AND THOSE, SO I SUPPOSE!

Suppose - I feel there's a spelling error.

MeAndMath

suppose

Gustavo Bandeira

Yep.

MeAndMath

send me an invitation

Gustavo Bandeira

Yep.

Eu não ia fazer por ter achado na base do stalking, exceto com convite, claro. Eu ia ficar me sentindo invasivo.

MeAndMath

6:52 PM

yep

user19161

@GustavoBandeira Looks like what I eat every day.

Gustavo Bandeira

@WillHunting I like eggplant.

Eggplant's juice is amazing!!!!

user19161

It is eggplant in US, aubergine in UK and brinjal in Asia.

user19161

Similarly, it is cellphone in US, mobile phone in UK and handphone in Asia.

MeAndMath

@GustavoBandeira o.o

user19161

6:56 PM

@GustavoBandeira Sounds terrible to me.

Gustavo Bandeira

It's beringela in Brazil, similar to Brinjal.

It's really cool!

MeAndMath

@GustavoBandeira disgusting

user19161

Similarly, it is okra in US and ladies' fingers in UK.

Gustavo Bandeira

I've been vegetarian for some time.

user19161

@MeAndMath Same!

user19161

6:59 PM

However note that ladyfinger is a kind of cake, not a vegetable.

user19161

@GustavoBandeira Any reason?

Gustavo Bandeira

@WillHunting Nope, only for fun.

@MeAndMath Foi?

MeAndMath

@GustavoBandeira sim

@MeAndMath What languages do the people there speak?

MeAndMath

@WillHunting there where?

user19161

@MeAndMath Where you live?

MeAndMath

user19161

@MeAndMath No, I mean the languages there, haha.

MeAndMath

8:06 PM

@WillHunting ?????

user19161

@MeAndMath OK, maybe this sounds stupid, but I am asking what they speak in Brazil!

MeAndMath

@WillHunting portuguese...

user19161

Hey @rob! Don't see Jonas around. :-(

robjohn

@WillHunting Perhaps he is not here.

MeAndMath

c'mon...everyone is leaving MSE?

robjohn

8:14 PM

@WillHunting I don't see any messages that he is going away.

MeAndMath

@GustavoBandeira are you there?

John Junior

@robjohn hi

robjohn

@JohnJunior hey there. It is certainly quiet

John Junior

@robjohn Indeed.

MeAndMath

Let's make some noise:AAAAHHHHHAAAAAAAAAA!!!!!!!111

8:24 PM

@GustavoBandeira oh,you are here!

John Junior

@robjohn I left you a video link a few hours ago about that.

MeAndMath

@GustavoBandeira What do you wanna talk about?

Gustavo Bandeira

@MeAndMath Sim. =)

MeAndMath

what are you studying?

say something !

Gustavo Bandeira

Wait a little.

Gustavo Bandeira

8:29 PM

Se não vão a gente que vai tomar ban.

MeAndMath

yes

robjohn

@JohnJunior yes, I found it.

@WillHunting: did you see any message about why Jonas is not here?

John Junior

@robjohn MarianoSuárez-Alvarez is going to write to him.

3 hours ago, by John Junior

Could you please look into why Jonas Tweuwen's account was "automatically suspended"?

robjohn

@JohnJunior about what? I don't see anything other than a comment he posted regarding being suspended, and he is not suspended now.

John Junior

@robjohn Just to ask what happened, I guess.

I got the impression that Jonas will not be back.

robjohn

8:37 PM

@JohnJunior because he got automatically suspended?

John Junior

@robjohn Yes.

robjohn

@JohnJunior so there were some angry people in the room at the time, I guess.

John Junior

@robjohn " sour people"

"Who are these sour people in this room?"

robjohn

If people are sensitive for one reason or another, something like foul language might cause them to flag. I will have to look back around then to see if there was a lot going on then.

John Junior

hi @Jackson

user19161

8:56 PM

@robjohn Not necessarily. It takes only one flag and all 10k users can see it. Then if they validate it it will lead to an autosuspension if there are enough validations.

user19161

My thinking is this. If someone hurts you, does flagging solve the problem?

user19161

Isn't it better to confront the person directly for emotional health?

robjohn

@WillHunting one sensitive person flags the others validate. Same thing.

user19161

Of course, I understand why one may not be able to confront the person. There are many reasons for that too.

robjohn

@WillHunting I would think so, but you know how children are on the playground.

user19161

8:58 PM

Well, I am actually thinking of my own life experiences now. :-)

user19161

@robjohn Hehe, you are a child too! All young in the heart.

John Junior

@WillHunting Did you get a chance to watch that movie?

user19161

@JohnJunior Not yet. But I have seen his lecture video. I can't remember which one.

John Junior

@WillHunting It's available on Youtube and it's more about his battle with his health than Physics.

I really have only one word to describe it and that would be "inspirational."

user19161

@JohnJunior I prefer watching "A beautiful mind" though the movie is different from the real story. The movie is inspirational +++!

Gustavo Bandeira

9:31 PM

@WillHunting Black swan $=$ A beautiful mind, but Nash dances ballet on this one.

@PeterTamaroff Where did you refurbish the book?

user19161

@GustavoBandeira There are stores which do this kind of thing.

Gustavo Bandeira

@WillHunting GTK

Peter Tamaroff

10:17 PM

@GustavoBandeira A lady at the public library does that.

how can I go on from day to day?who can make me strong in every way?where can I belong ?Where can I be safe,in this great big World of sadness?

I'm thinking on sending this to Peter.

With the purpose of cheering him up. Maybe he's bad with all this.

MeAndMath

nice!

Peter Tamaroff

@GustavoBandeira Bad with what?

user19161

@PeterTamaroff WTF!

Gustavo Bandeira

@PeterTamaroff Suspension.

user19161

10:40 PM

@GustavoBandeira Jonas you mean.

Peter Tamaroff

@GustavoBandeira Suspension? Is JT still suspended?

Gustavo Bandeira

XD XD XD

Jonas

XD XD XD

user19161

@GustavoBandeira It is not a big deal, seriously. I was suspended from chat too. It is just half an hour.

Gustavo Bandeira

WTF Peter. This is your fault.

@WillHunting Serious?! Why?!

user19161

@PeterTamaroff Now I know why you call me Dawg.

user19161

Gustavo Bandeira

Coursera says there's no limit of courses I can enroll in.

But I can't enroll in more than two.

when I was a child I tried to understand this

Cáustica (óptica)

Em óptica, uma cáustica é a superfície dos raios de luz refletidos ou refratados por uma superfície curva ao objeto, ou a projeção dessa superfície de raios em outra superfície. O termo cáustica pode também referir-se à curva na qual os raios de luz são tangentes, determinando uma fronteira da superfície de raios como uma curva de luz concentrada. Portanto na imagem da direita, as cáusticas podem ser os traços de luz ou suas bordas brilhantes. Estas formas normalmente têm pontos singulares cúspide. Estas concentrações de luz, especialmente de luz solar, podem chegar a queimar. A palavra ...
