Mathematics - 2012-12-04 (page 3 of 4)

@JayeshBadwaik Yeah, it is really hard to chew all of the different parts.

@GustavoBandeira haha

4:58 PM

@N3buchadnezzar Ohh. I would have preferred to take all of them separately.

Gustavo Bandeira

@charlie I'm gonna sleep a little. Cya

@GustavoBandeira you sleep a lot...

@JayeshBadwaik Seperately?

@N3buchadnezzar Linear Algebra - 1 course. Analysis - 1 course. Topology - 1 course. Real Analysis separately 1 more course.

Yeah, but this is the introductory course to them. Or prequisite if you want.

If I want to study Topology, or fucntional analysis. This course is prequired.

Gustavo Bandeira

5:00 PM

@charlie Actually not, I went to sleep at 10A.M.

I'm going now.

@N3buchadnezzar Ahh, that's strange.

user19161

Over and out!

@GustavoBandeira sleep tight!

@JayeshBadwaik Oh?

@N3buchadnezzar I don't see the logic. It seems like first eat the crust of all the fruits, and only then you can proceed to the core of any one you choose.

5:03 PM

@JayeshBadwaik Eating the core before the crust would be a bad idea..

And is it not wise, to taste all the fruits to figure out which ones prefer?

@N3buchadnezzar May be, may be.

@JayeshBadwaik If fruit A tasted good, and fruit B tasted like poop. I would not want to go around eating poop all the way to the core.

If something taste like poop, you should not be forced to continuing to eat it..

@N3buchadnezzar Don't you have the option of backing out of the course until the second mid-sem?

peoplepower

Though, a lot of the time, a deeper examination is what maintains my interest.

@N3buchadnezzar Can not be tasting be held outside the formal coursework?

5:06 PM

@JayeshBadwaik How?

@peoplepower Exactly, if I want to be interested, I want to be able to explore as deep as possible. Having so many different topics to study diminish that.

@JayeshBadwaik absolutely

@JayeshBadwaik One is required to take 4 courses each semester, else one does not get loan/money to keep studying. Backing out half way, would mean taking another course instead. And starting half way, would be really tough

@JayeshBadwaik Indeed

@N3buchadnezzar Ahh. I see.

@N3buchadnezzar By allowing this course to be audited? So, that people can still attend at their own pace. They need not attend the portions they start to dislike.

Thats why I am taking most of the subjects later =)

5:09 PM

@N3buchadnezzar Fair decision.

Yeah, one can attend. But courses often crash, or one does not simply have time to attend all the "cool" courses.

@N3buchadnezzar Ahh. :-(

@JayeshBadwaik We need to hand in 4 papers each week, along with mandatory experiments (in physics, biology, chemestry). Ofcourse I am only taking math and physics.. So yeah, it is hectic.

Given a matrix, it's clear how the linearly independent columns are important, they span the image set. What about the linearly independent rows?

@WouterZeldenthuis They indicate the kernel I might say.

5:15 PM

indicate @Jayesh?

@WouterZeldenthuis Here

@WouterZeldenthuis Basically, they are equivalent. The independence of rows and column, but the linearly independent column span the image set. The zero row might indicate information about the kernel. Right now, I cannot say exactly what is the relation, but this much I am sure.

thanks

hello people.

@TessaDangerBamkin Hello Tessa

@TessaDangerBamkin Hi. I originally thought you were Tesla Danger.

5:28 PM

i could be if you liked me to be

I would like you to be then. :P

my ring tone is nikola tesla by amanda palmer and her friends

have you guys ever seen that "singing Tesla coil?"

@TessaDangerBamkin nice.

@Charlie yup. cool.it.is.

@JayeshBadwaik hahaha

5:30 PM

I have not

►

This is so nice!

@Charlie Ahh never saw that before.

@JayeshBadwaik cool, isn't it?

@JayeshBadwaik what about this?

@Charlie nice.

@JayeshBadwaik :D

5:35 PM

:D

user19161

6:00 PM

Got the 4th accept today, yay!

@JasperLoy woohoooo

@JayeshBadwaik do the linearly independent rows span the cokernel?

maybe that's not right

@JasperLoy Jasper Jasper Jasper Loy:it's J-a-s-p-e-r

@WouterZeldenthuis You can call it a row space Row Space

The orthogonal to the rowspace is the kernel.

user19161

6:18 PM

Got my fifth accept today, yay!

@JasperLoy You're good today, Jas!

user19161

@Charlie "I'm bad", he said. =)

I am badman! he said.

@N3buchadnezzar HAHAHAHAHA

Take Topology they said, it will be klein bottles, and toruses they said.

4

6:24 PM

@N3buchadnezzar Bleh I said!! That's algebraic topology I guess.

@N3buchadnezzar it's everyone thinks....

Hmm, can I get all the starred messages?

@JayeshBadwaik Yeah, luckily that is a separate course here.

@Charlie Indeed

@JayeshBadwaik What are you studying again ?

user19161

OMG I think my supervisor just joined the site...

Right now, preparing for entrance exams to graduate courses. For that, I am studying the following books
1. Algebra - Artin
2. Linear Algebra - Lang
3. PMA - rudin
4. Topology and Modern Analsyis - Simmons
5. Topology - Munkres
6. Complex Analysis Ahlfors
6. Complex Analysis Krantz

user19161

Hey @amwhy are you around?

6:33 PM

@JasperLoy Hehe. Good luck.

user19161

@JayeshBadwaik Unregistered though.

@JayeshBadwaik Pma?

@JayeshBadwaik And is the Munkres book, any good? It is our primary book in Topology too next year.

@N3buchadnezzar Its really really good.

@N3buchadnezzar Baby rudin. Principles of Mathematical Analysis.

As I walk through the valley of the shadow of death
I take a look at my life
And realize there's nothing left
'Cause I've been brassing and laughing so long
That even my momma thinks that my mind has gone

@Charlie Causseee weee areeee alll living in a gangsta paradise

(with big booty females)

6:39 PM

@N3buchadnezzar tell me are we so blind to see

That the ones we hurt are you and me?

Been spending most their lives living in the Gangsta's Paradise

ahaaaaa aaaa aaaa a a

@Charlie didnt know you were into ghetto music

@N3buchadnezzar I like this song! Because i like the movie where this song plays

You mean the music video?

6:42 PM

@N3buchadnezzar with michelle pfiffer

I like this and that.

@Charlie What do you think? =)

@JayeshBadwaik Is the munikres book most about point set topology, or algebraic?

@N3buchadnezzar kind nice :)

I only listen to music that has swag.

@N3buchadnezzar wow

You took me serious?

6:48 PM

@N3buchadnezzar Half of it is general topology. The other half is algebraic topology.

@N3buchadnezzar yes, why not?

user19161

Six accepts today.

@JasperLoy Rock n Roll baby.

@Charlie Cause I have no idea what swag means.. This song is cool too youtube.com/watch?v=twqM56f_cVo

user19161

@N3buchadnezzar Swag is promotional material given out to consumers.

user19161

6:52 PM

For example, SE once gave top users free stickers, pens and shirts as swag.

I thought it was something related to hipsters..

@N3buchadnezzar hahahahah

@Charlie urbandictionary.com/define.php?term=swag

@N3buchadnezzar nice

@N3buchadnezzar You are not mistaken

6:54 PM

@JayeshBadwaik I like how I refered to A, then you refered to my post me and said: Hey look at A.

Because that is just how meta we are.

@N3buchadnezzar Duuude, I did not quote you, I had already hit enter by the time you posted.

user19161

@old I got 290 today with 6 accepts!!!

@JasperLoy Wow - that is definitely more than I ever got in a day ...

... and in fact in a week, often :)

In my case, a lifetime. :P

Two lifetimes for me and my cat.

7:05 PM

Brian M scott makes that in a minute

Arturo, makes that when he blinks in his sleep.

haha

Seems like he made anything from 25-50k rep, after retiring from the site. That is pretty crazy.

Just on delayed rep, and accepted answers.

wow...

yeah, he is near 150k now.

user19161

7:25 PM

@amwhy Did you see Tony's comment on the distinguished answer?

user19161

I am pissed it got two downvotes when the other two answers say the same thing too and didn't get any downvotes. Do people read answers before downvoting?

user19161

@old I would like your opinion on something.

user19161

Where has everyone disappeared to? =)

@JasperLoy no where land

user19161

Anyway now that the asker has unaccepted my answer, I shall delete it since it got three downvotes, but it is not wrong.

user19161

7:39 PM

But it shows me that the voters don't read answers carefully before downvoting.

user19161

@OldJohn Are you around?

I am asking because I have a very basic topology question.

@JayeshBadwaik m

@N3buchadnezzar ?

7:52 PM

I tried to star your message

@MattN. If you have some time at hand, ask me, I might learn a thing or two. :-)

@N3buchadnezzar Its starred.

@JayeshBadwaik I don't, I'm sorry.

@MattN. No problems. :D

Looks like he's afk. I'll see you all later!

Bye.

user19161

7:54 PM

Anyway I still have 5 accepts, so not too bad... =)

sonicboom

What is the point of LU-Factorization? Is it computationally more efficient than computing the inverse of a matrix when solving a system of linear equations? Is that it?

@JayeshBadwaik I just answered it myself.

@MattN. :-)

I wonder how my brain works. Sometimes it seems as if it's more productive to sit there, thoughts idling around thinking nothing and then all of a sudden the answer is all there, cristal clear, without any work.

Very frustrating that this process seems to be random.

BBL

geez...

8:00 PM

Me...

Ok lets go

1...2...3...4....

C´mon Jayesh

star spangled banner

WTF?

8:03 PM

8:15 PM

Hey Jay...

@Charlie ?

Don't make it bad, take a sad song and make it better

@Charlie It should be Hay Jay

Take a sad song, and make it better

@Charlie Heeeey jews

8:17 PM

@N3buchadnezzar Are you calling me hay, bro? Be careful, I can hide needles really well. :P

@JayeshBadwaik remember to let her into your heart

@Charlie then you can start to make it better.

Yesterday, all the jews seem so far away.

@JayeshBadwaik Hey, Jay don't be afraid, You were made to go out and get her

@N3buchadnezzar hahaha.

8:21 PM

But now it looks like they are here to stay.

Oh, how I long for yesterday.

@N3buchadnezzar you'd better delete it.....

@JasperLoy sorry - been afk - no kitchen here at the moment, and it makes life a bit more complex :)

@Charlie remember to let her under your skin, then you can start to make it better

user19161

@OldJohn Anyway, it's alright I deleted my answer. It's just a matter of words in that question, not the math. =)

@MattN. Sorry Matt - was away cooking

8:23 PM

And anytime you feel the pain
Hey, Jay, refrain
Don't carry the world upon your shoulders

For well you know that it's a fool who plays it cool
By making his world a little colder.

user19161

Whoa I got a comment from the great Bill Dubuque!

Hey, Jay, don't let me down
You have found *her* now go and get *her*

Remember to let her into your heart,
Then you can start to make it better.

So let it out and let it in
Hey, Jay, begin
You're waiting for someone to perform with
And don't you know that is just you?

8:27 PM

hey jude, you'll do,
The movement you need is on your shoulder.

Hey, Jay, don't make it bad
Take a sad song and make it better
Remember to let her under your skin
Then you'll begin to make it better (better, better, better,better, better, oh!)

@Charlie Na na na na na ,na na na, hey jude... $\times \infty$

@JayeshBadwaik Reminds me of Xkcd, and batman... =)

Na na na na na ,na na na, batman!

@N3buchadnezzar Have you seen watman?

Everybody sings: NA nanananana nanana Hey jude, jude jude jude Oh

8:29 PM

@JayeshBadwaik no?

@N3buchadnezzar can you appreciate jokes about programming languages? In which case, I will link you the video titles wat by greg bernhardt, searching the link right now.

@N3buchadnezzar Here

@JayeshBadwaik Seen it before

Geez..it's so hot in here.. i'm melting...

@N3buchadnezzar Cool!!

@Charlie Its like -15 here

8:38 PM

@N3buchadnezzar So you know programming?

@Charlie Take off all the clothes!

@N3buchadnezzar that's good

@JayeshBadwaik I know simple matlab and maple

I understand the basic syntax, can write simple loops and alike.

@N3buchadnezzar Okay. Nice.

Nothing fancy though

8:39 PM

Did you appreciate the jokes?

Taken a single course in it.

Of course!

:D :D

I wish I could take inter at university...

inter?

Then I could finnaly have a inter course

8:41 PM

ba dum tss

@N3buchadnezzar Poor Forever Alone Guy.

user19161

@JayeshBadwaik Sounds like me...

Destroy All Software

@JayeshBadwaik Just install Windows 8, problem solved.

8:46 PM

@N3buchadnezzar is it really good?

...

@N3buchadnezzar Yeah. My friend actually upgraded (or is it downgraded?) from win 7 to win 8.

I was like WTF? You are not my friend anymore, first you use windows, and then win 8

@JayeshBadwaik Smack his bottom with his tablet.

@N3buchadnezzar He lives 1300 km away, so I don't have to endure his laptop, but still.

@N3buchadnezzar steady on, lads - we don't want Harry Potter getting excited again!

8:49 PM

@OldJohn Hahahahahahaa

where this harry potter thing came from?

8:52 PM

hi

hello

can anybode me with small number theory?

@user51650 we will try ...

Can every number greater than ${2012^2012}$ be written in the form $x^2 + y^3 + y^6$

user19161

@user51650 You should just ask and not ask to ask.

8:56 PM

@user51650 that question appeared on MO recently, didn't it?

user19161

Hahaha, another 2012 question!

something similiar has appeared

but i dont know how to solve that one

user19161

Next year, it will all be about 2013!

@user51650 I suspect that you might have more success if you ask that question on MO

@JasperLoy no
