Mathematics - 2012-07-06 (page 4 of 6)

12:08 PM

Not easily, or what do you mean?

well, obviously, i have put little thought into mine, i just took what the system gave me. i rather like that it has D4 symmetry, but that's just dumb luck.

now, Jasper's..perhaps he's a mariah fan, or perhaps he's not, and he's being ironic. either way, it says something (although not sure what...).

some people depict themselves, or what represents themselves in some symbolic way.

Rajesh D

Then there are some really wierd people here @DavidWheeler

David Wheeler

but yours, Gigili...is it an admonition to hush? a reminder not to let some vital secret slip? or a finger held up in warning?

Rajesh D

@JasperLoy : When was it?

user19161

@RajeshD weird

Rajesh D

12:16 PM

ok

but answer me

user19161

@DavidWheeler I love MC's songs!

David Wheeler

the black-and-whiteness...the starkness, and "partialness" of the image...reminds me of film noir

Rajesh D

I used to like them too @JasperLoy

David Wheeler

i like"tuts my barreh" does that count?

user19161

@DavidWheeler The three are isomorphic.

David Wheeler

12:20 PM

3?

user19161

@DavidWheeler Do you know how to use the left arrow?

David Wheeler

what do you mean?

user19161

@DavidWheeler Well, one clicks on the right arrow to reply and the left arrow to see what is being replied to.

David Wheeler

oh, you mean:

@JasperLoy this

user19161

But some chat users insist on using the keyboard only and confusing others.

user19161

12:24 PM

They come in, reply to a message 9000 years ago, and expect us to know what they are saying.

user19161

One then needs to read 9000 years of transcript to figure out what is going on.

user19161

@DavidWheeler Yes!

David Wheeler

well, i'm sorry, i wasn't alive 9000 years ago. what did i miss?

Frank Science

@JasperLoy What? You seems criticizing the keyboard-only users.

Gigili

Who criticized whom?

David Wheeler

12:27 PM

i don't often "ping" people...i feel like it's demanding their attention.

user19161

@FrankScience You are using the arrow to reply? That is a miracle!

user19161

@DavidWheeler Er, one can just turn off pings you know.

Gigili

@DavidWheeler Well, an admonition to hush it must be.

Frank Science

@JasperLoy It's horrible for a keyboard-only user to use mouse!

user19161

@Gigili Yes, you have many secrets like me.

David Wheeler

12:28 PM

if there is a specific person i want a reply to a specific statement to, that's a little different.

Gigili

But I like how he insists on not using that right/left arrow thingy.

David Wheeler

unfortunately, this chat interface is too limited. i regard it as something like 3 sentences of disposable space.

Frank Science

@DavidWheeler Where is better?

Rajesh D

@JasperLoy What is this right/left arrow thing?

David Wheeler

i don't know, honestly. it's just not like actual conversation.

user19161

12:32 PM

@RajeshD You just used the right arrow to reply to me.

David Wheeler

@FrankScience ^

user19161

@DavidWheeler Do you want skype then?

Rajesh D

Its not working for me

apparently

user19161

@RajeshD it's

Rajesh D

How

Gigili

12:33 PM

@JasperLoy it is *

user19161

@Gigili No, we must preserve the original flavour of the OP when editing.

Frank Science

@DavidWheeler What do you mean by actual conversation?

David Wheeler

@JasperLoy not necessarily.

Rajesh D

@JasperLoy Please explain how to use right/left arrow

user19161

@FrankScience Face to face. I will see you there. I am taking a space ship there now...

David Wheeler

12:34 PM

@FrankScience talking face-to-face.

Frank Science

@DavidWheeler It's impossible for online text chatting.

user19161

@RajeshD I just mean that you click on the arrow to the right of the message you want to reply to. You click on the left to link backwards. Elementary, my dear Rajesh.

user19161

@FrankScience Webcam.

David Wheeler

@FrankScience this i know. i also know i can converse with people i would never even know of, otherwise. it's not without some advantages.

Frank Science

@JasperLoy I have no. And I meant text chatting.

Rajesh D

12:36 PM

@JasperLoy Ah Now I see the use of right arrow, I was thinking of pressing the right arrow key of my keyboard earlier!

Frank Science

@DavidWheeler So here is proposed to discuss math problems ad hoc, not for the other reason.

Gigili

@JasperLoy Uh, my dear Rajesh. I see butterflies in the room!

user19161

@FrankScience Yes you are too serious Frank.

user19161

@Gigili Yes, my dear Gigili.

Rajesh D

There is actually another method you can click on reply to this message on the menu which pops up when you click on the left end of the message

David Wheeler

12:37 PM

webcams are so...personal. it's one thing to walk up to a group of people conversing in public, and say: hi there! it's quite another to walk up to someone and say: can we talk...in private?

Frank Science

@RajeshD There's no pure keyboard way.

David Wheeler

also, the Lithium Mining Consortium charges me $0.0001 every time my mouse moves

2

Rajesh D

@FrankScience Darn I have a strong dislike towards switching between the keyboard and the mouse pad, very irritating

user19161

@DavidWheeler LOL

user19161

@RajeshD You must be a fast typist then.

Rajesh D

12:40 PM

@Gigili I don't understand why you mentioned me

Frank Science

@RajeshD What?

Rajesh D

No not at all

I just hate the switching part

Gigili

I wouldn't mention you, you're mistaken.

Rajesh D

I look at the keyboard when I type, I am so lame at typing, and I use only two fingers

David Wheeler

one wonders, @Gigili, whom he should have took.

user19161

12:41 PM

You know, then there are people who already know about the arrows but don't apply that knowledge to understand the conversation.

Frank Science

@RajeshD Well, so I seldom use mouse.

Gigili

@DavidWheeler Anyone, except me, please!

user19161

@Gigili Because you are taken?

David Wheeler

@Gigili very well, i accept you.

user19161

@DavidWheeler taken

Gigili

12:44 PM

@DavidWheeler You had no choice.

David Wheeler

@Gigili you used the forcing model.

user19161

Cohen's method of forcing as expounded in Kunnen's Set Theory.

Rajesh D

Would someone mind explain me what this sentence mean?

user19161

@RajeshD explaining to me

Gigili

@JasperLoy There's no why.

user19161

12:46 PM

@RajeshD It just means she thought my sentence was too cheesy.

David Wheeler

i used to live in wisconsin

user19161

There are simple explanations for seemingly complicated things.

Gigili

@DavidWheeler Oh, where there? If you don't mind my asking.

David Wheeler

when i was in college, we used to play a game: it required three people. we'd start a conversation, but you wouldn't respond to the person you were responding to, but what the other person said.

@Gigili Madison

anon

you wouldn't respond to the person you were responding to division by zero

2

David Wheeler

12:50 PM

at any time, any participant could "up the stakes" by then replying to the second person previous, in which case the others had to follow suit

@anon while you go infinite, anon, the rest of us will carry on :P

robjohn

@anon: hey there.

Gigili

@DavidWheeler I lived there for about six months, that's why I asked. Not that I'm interested.

anon

yo

David Wheeler

eventually, it became predictable what a response would be, and pre-emptive replies took over

@Gigili i don't require you to be "interested"

anon

seen 8 min ago totally not stalking

2

Gigili

12:55 PM

@DavidWheeler I don't care what you require me to be.

robjohn

@anon how are things this morning?

David Wheeler

@Gigili harsh, but fair

anon

fair. aaaand there's jm.

Rajesh D

Darn That was the part of your senetence @Jasper. Seems like I should look at things more carefully over here

J. M.

howdy, howdy, y'all. :)

David Wheeler

12:57 PM

@JM hello, thee of the blue name

anon

is it thee, or thou?

David Wheeler

it should be "thou" but it doesn't "scan" as nicely

J. M.

@DavidWheeler Let's all ignore that tiny detail, unless Bad Things™ are happening here... ;)

David Wheeler

if I may ask, from whither dost thou hail?

Gigili

@tb I have an important question and don't know how to find you.

Oh, never mind. Found a way.

J. M.

12:59 PM

Speaking of which... did Bieber have gender-reassignment surgery lately?

anon

Beiber is now Mariah someone.

Carey I believe.

Rajesh D

Thats exactly what I mean when I asked him "When was it?"

David Wheeler

dailysquib.co.uk/entertainment/… apparently so

@JM i only asked because that is the state greeting of texas, mandated by law when Bush was governer

J. M.

@DavidWheeler Ah, right. Dubya...

BenjaLim

@anon it is bieber

anon

1:05 PM

w/e

Gigili

I think it should be the other way around, since questions are more important than answers.

There would be no answer if there were no questions.

+5, answer; +10, question.

Or +15, +35.

Q: How hot is this cutie?

Hey there is a girl I'd like to hook up. Do you like her? http://www.sv-hutthurm.de/Fuchs_Lisa_1384a.JPG

egjactly.

Rajesh D

Oh my What a nice catch!

BenjaLim

1:08 PM

80 flags guys

David Wheeler

well, clearly, the first thing to check is if she's linearly independent.

J. M.

Also check the surface for sections of positive and negative curvature...

Gigili

@Gigili Ah pft, I can't edit that typo. Go kill them all with one bullet.

J. M.

@Gigili Better?

David Wheeler

@Gigili no grassy knoll required! magic!

anon

1:11 PM

Gigili

@JM Hih, thank you!

kind mods=gods, unkind mods=evils.

gods can be evil

Rajesh D

There are some f****ists here be careful!

J. M.

"One man's meat is another's poison."

@RajeshD I'm not sure why that had to be censored myself...

@anon Maybe for Asaf. :)

Rajesh D

David Wheeler

i once worked with a really nice guy named amar. one day, our department ordered us pizza, as a reward for a job well done. his face lit up when he heard...and then when he heard "pepperoni"...it fell. broke my heart.

Fortuon Paendrag

@David Sounds like me :(

Rajesh D

Whats wrong with pepperoni? Do they mix beaf with sheep?

David Wheeler

1:15 PM

it can contain pork

J. M.

@RajeshD Most pepperoni I know is pork...

(plus extenders)

Rajesh D

pork is okay for Hindus not beaf though

anon

*beef

Fortuon Paendrag

Well, not if you're a Brahmin..

J. M.

@RajeshD Yeah, and on the flip side, they're fine with beef but not with pork.

Rajesh D

1:16 PM

no nonveg is ok for a Brahmin right?

anon

mmm, brahms

Fortuon Paendrag

Yeah, Brahmins generally avoid meat of any kind.

He's eating us!!

Gigili

I recorded two audios without pressing "start recording" button. I'm silly like that.

Rajesh D

"audios"

Fortuon Paendrag

@Anon, has Kannappan been around at all lately?

anon

1:19 PM

nope. not for ages.

David Wheeler

that happened with Brian Eno and Robert Fripp during their last recording. they made what they described as a perfect record, only to discover when finished they hadn't turned on the recorder.

Rajesh D

Audios = goodbye in spanish

Fortuon Paendrag

@anon That's unfortunate.

@RajeshD I think that is "Adios"

Rajesh D

Whats in a spelling mate

Fortuon Paendrag

:)

Rajesh D

1:20 PM

That was the closest thing to that

David Wheeler

well "Oddio-s" means "goofballs" in english

of course, i also lie a lot

Gigili

There's also "Odd ios", and it has nothing to do with apple products.

David Wheeler

lol

Rajesh D

Shouldn't the cutie question be deleted?

anon

already is

seconds after you opened it in fact

Rajesh D

1:26 PM

ok I see now

I am lucky

Gigili

The cutie question is closed but the cutie will be there for you forever.

Rajesh D

where?

Gigili

I see you're really busy @Ilya.

liangtehz

if I am weak in maths, what are the online ebook or website I can learn for undergraduate math?

anon

what kind o math?

user19161

1:33 PM

@RajeshD sentence

user19161

@BenjaLim OMG.

user19161

@RajeshD beef

Rajesh D

@JasperLoy Thats very kind of you.

@JasperLoy Thats even kind

user19161

@RajeshD that's

user19161

@RajeshD that's

Rajesh D

1:35 PM

That's

liangtehz

calculus, discrete maths

user19161

@Gigili She's not my type.

Rajesh D

@JasperLoy I wonder why do you keep popping in and out?

user19161

@RajeshD Ah, no reason.

user19161

If there is a reason I would say so.

Rajesh D

1:37 PM

@JasperLoy everything has one

however silly it is

user19161

@RajeshD Well, you know what I mean. No special reason then.

Gigili

One what?

user19161

@Gigili Reason.

user19161

@liangtehz If you are really weak I suggest you read more books.

Gigili

One what reason?

liangtehz

1:38 PM

@Jas

Gigili

@JasperLoy I love your useful and unique suggestions.

user19161

@liangtehz For me, learning things seriously online is not the way.

liangtehz

@JasperLoy what kind of online books which I read? there are so many out there.

user19161

@liangtehz Are you taking classes in a university?

liangtehz

I have completed my degree.

user19161

1:39 PM

@Gigili Yes, I tell people special things they won't hear elsewhere.

liangtehz

Looking back, I barely scrap through

user19161

@liangtehz Then what is your purpose of studying these things?

J. M.

@JasperLoy 'cause they'll always be your baby?

user19161

@Gigili They really are useful. But this will only be realized many years later.

Rajesh D

@JasperLoy You will be Idolized then?

liangtehz

1:41 PM

Just a goal or something which I hope to work on and improve since maths is a core skill in life

user19161

@liang I am waiting for your reply you know.

J. M.

@liangtehz It really depends on what you want to use math for. Note that arithmetic is just one part of mathematics, though.

user19161

I asked you for the purpose not for fun but to help you.

Rajesh D

" maths is a core skill in life"

Many people here wish it was

Gigili

@JasperLoy Das ist nur deine Meinung.

user19161

1:43 PM

@liangtehz Oh sorry, I needed to refresh my browser.

liangtehz

@JasperLoy it alright

user19161

@liangtehz If that is your attitude then you should go for the hardest books.

anon

@JM or so one thinks

user19161

@liangtehz Really, the question you asked is not answerable. Calculus and discrete math can mean many things. And different people learn best from different styles. You should really take a look at all the books available and decide for yourself.

Rajesh D

Arithmetic for graduate students?

user19161

1:45 PM

@anon That is often quoted in this room somehow.

Rajesh D

@JasperLoy Are you trolling liang?

user19161

@RajeshD No. When people ask a serious question I give a serious answer.

J. M.

@anon Hell of a title, that. ;)

anon

"There are five elementary arithmetical operations: addition, subtraction, multiplication, division, and… modular forms" - Martin Eichler

user19161

@RajeshD I am not going to pick one book for him when there are so many.

Rajesh D

1:47 PM

He obviously cannot have a look at everything. The proof in the pudding?

user19161

@liangtehz Firstly, must it be online and for free?

Rajesh D

@anon Then I know 80% of it.

user19161

@anon He might think you are recommending him that now.

anon

Yes. Highly recommended. A read-through should take about 2 weeks.

Rajesh D

Who knows he may read it and let his genious out! Then @anon will be appreciated

Fortuon Paendrag

1:51 PM

@anon I think Peter Sarnak says that in the Fermat's last theorem documentary.

user19161

@anon Let's not confuse him.

user19161

@liang Must it be online and for free?

user19161

@RajeshD Hey, maybe now he thinks I am trolling him!

Rajesh D

Well well well

user19161

Sigh, I am always misunderstood...

user19161

1:55 PM

What happened to you liang? Are you still here?

Rajesh D

Now a days my comments rarely get starred. Am I so sane?

@JasperLoy lol

user19161

OK I give up. My good intentions were not well-received.

Rajesh D

@JasperLoy Don't loose your heart. He might be having some tech difficulties.

J. M.

@anon Not counting prerequisites...

user19161

@RajeshD lose

J. M.

1:58 PM

@JasperLoy A loose heart is likely to be a medical emergency...

user19161

@JM A loose heart is likely to be lost.

user19161

According to my browser, liang's avatar has left.

user19161

@FortuonPaendrag He's really left. He might be back in a few years I feel.

Gigili

@JasperLoy You were unnecessarily helpful and he couldn't believe it.

Fortuon Paendrag

@JasperLoy That is quite unfortunate. He was very kind to me.

user19161

2:03 PM

@Gigili Exactly. I don't give people a single stupid answer just for the sake of it.

user19161

@FortuonPaendrag I saw him in the TeX room a few days ago.

user19161

@FortuonPaendrag He was kind to me too. I really wonder why he felt upset.

Eugene

@anon ah yes. serre's book whose title reveals almost nothing about its content.

user19161

@Eugene Also, Weil's Basic Number Theory.

Eugene

@JasperLoy that one is not so awkwardly named IMO

robjohn

2:13 PM

@JM hey there :-) you look like the cord that goes with my headphones.

user19161

@Eugene Well, it says "basic".

Eugene

@JasperLoy yes but not elementary.

J. M.

@robjohn Heh. I was going for an abstract Ouroboros myself...

@Jasper Lucky for you that there are no toothy old ladies for neighbors who scream in agony at the slightest sound that escapes your house.

user19161

@FortuonPaendrag Oh it's not very loud actually. It's only loud when I start to sing myself.

Fortuon Paendrag

Ah, that is good to hear. It would be a travesty, if you were ever convicted.

@MattN OMG OMG you have asked so many AT questions

user19161

@ben Technically the answer to the above question is somewhat flawed in that it shows only one direction but concludes the other direction.

Mark Dominus

@JasperLoy When I see a question has a -1 or -2, I usually skip it. When I see one that has a -8, I have to go look at it to see what was wrong with it.

Mark Dominus

2:43 PM

I find that whole site intensely boring.

BenjaLim

@MarkDominus I am going to ask on ELU the origin of the term "to get maggot"

Jonas Teuwen

@BenjaLim Probably it has to with the fact if you get maggot really bad you die and you actually get eaten by maggots.

BenjaLim

@JonasTeuwen XOXOXO

Jonas Teuwen

Like so obvious. I am the etymology expert.

@Gigili:what did you mean?

Jonas Teuwen

@Ilya Want to switch? Only like 600 or so.

Ilya

@Jonas: yes

trust me, you don't want to :)

Jonas Teuwen

Maybe I should put something random on it and if they complain I can check it for real?

user19161

@ilya Just now what did you mean about what is up with me?

Jonas Teuwen

Oh... here I have to check every number... and check if it makes it worse or easier. O.M.G.

Mark Dominus

somebody wants to close this?

@Gigili ah, I wasn't here. Even chrome! was closed

Gigili

@Ilya Umm, no idea then.

Jonas Teuwen

@Ilya 30 minutes?

@Ilya For the ones that can actually pass...

Ilya

@JonasTeuwen 600x0.5 = 300 hours

7.5 weeks

Jonas Teuwen

@Ilya Some only take 2 minutes.

Ilya

Jonas Teuwen

Like 75%.

Ilya

well, 7.5 weeks x .25 = 1.75 weeks

only grading exams

only for those who passes

user19161

@JonasTeuwen Why so fast?

Gigili

I hate it when the OP edits the part of the question I commented about!

Jonas Teuwen

@JasperLoy Okay, maybe bit longer, but on average. Some are complete shit.

So those take 15 seconds. To give them a 1 or 1.5.

user19161

2:56 PM

@Gigili It's OK. Everything is time stamped.

Jonas Teuwen

@Ilya Yea.

user19161

@JonasTeuwen Maybe some scripts are empty!

Ilya

@JonasTeuwen how many of you are grading this?

Jonas Teuwen

@Ilya I think... 10 or so? But I have different courses.

Ilya
