« first day (1404 days earlier)      last day (3621 days later) » 

10:00 PM
@TedShifrin Anyway he disappeared. Maybe wanted me to say "See you in your dreams" lol
 
@MikeMiller Not a single one whose homework you like to grade?
 
I think you dreamt his appearance.
 
I am thinking if I would get Spivak's Differential Geometry set one day.
 
@DanielFischer There are a few that regularly do very well, but alas, most of the assignments are tedium, so there's generally nothing interesting for students to write.
 
@Jasper: I have an old set I will be getting rid of when I empty out my office.
 
10:01 PM
@TedShifrin OK, thanks. But I like my books new, lol.
 
@TedShifrin I did the math, and I need an 18% average on my final paper and final in sociology to pass the course... now I need to determine if I think I did a 36% job on the paper.
 
Mine are like new, @Jasper. I treasure my books. But I understand.
 
@MikeMiller Boring assignments are evil.
 
Oh good grief, @Mike.
Sociology isn't necessarily boring, but math geeks tend to be narrow-minded.
 
I will only be bringing 9 books if I go to US for grad school. No more than that.
 
10:03 PM
@TedShifrin Please don't call me narrow minded. I signed up for this class because I was interested in the subject matter and I was excited to learn. The professor managed to make it painful to even attend.
 
ah, one of those scintillating sorts?
However, about 1/3 of my advisees, in my 30+ years' experience, have been very narrow. Some extremely broad with multiple majors.
 
I took quite a lot of English modules back then.
 
@TedShifrin Luckily, our core casts its net so widely I can always take a variety of classes that are all interesting to fulfill the requirements.
 
If I can go back and redo my undergrad, I would take all the math modules.
 
One of, if not the, best classes I ever took was a history class
 
10:04 PM
@Jasper proves my point ...
History and math are the two subjects most ruined by horrid teachers, so that's good, @Mike.
We've had plenty of horrid math teachers ... it just doesn't drive us away the way it does most people.
 
There's a reason I was a polisci and econ major when I got to college, @TedShifrin
 
If I could go back to secondary school I would have taken French or German.
If I could go back to before I was born, I would choose elsewhere to be born.
 
I've ended up with a lot of econ majors in my honors multivariable math course who've ended up with a double major in math @Mike.
I'd be a cat if I had a choice, @Jasper :P
 
@TedShifrin Are you serious? It is not nice to be an animal.
 
I love cats, @Jasper.
 
10:09 PM
(The course was "women in political revolutions", by the way - one of the few courses I kept the books from)
 
@TedShifrin OK, but that is different from being a cat, lol.
 
I'm not sure being human is all it's cracked up to be, @Jasper.
 
@TedShifrin I am not sure if plants are sentient beings.
 
My sister the vegetarian would be upset to find out that they are.
 
[Joke beyond comprehension of most]
 
10:13 PM
great, @Alec ... so now you're hating on women along with your gay slurs a few weeks ago ... Who's next?
 
@AlecTeal I understand, and it's not a joke.
 
@TedShifrin I called Justin Beiber a "Little faggot"
 
@AlecTeal Why did you do that? That is bad.
 
Well, I despise Bieber, but I'm a faggot, so I take these things personally.
 
I think lots of flags will come soon...
 
10:14 PM
[serious, but I don't want everyone to know]
 
LOL @Jasper
 
People do flag "faggot".
@AlecTeal So you are gay?
 
No.
 
My first days in this chatroom were tumultuous with Twink around ...
 
@AlecTeal You said you had a boyfriend?
 
10:15 PM
I dunno what the hell you're on about....
[This]
 
A boy with a boyfriend, doesn't that make you gay? I am confused.
 
What are you babbling about?
 
Oh, so you like both I see. That is also called gay lol.
 
Um, this is all on you, @Alec. Chill.
 
10:16 PM
timeout?
weird, I got told I was on "timeout" by a bar up top when I tabbed back in
 
Timeout? Nobody is getting upset.
 
@MikeMiller Hai, yo.
 
@PedroTamaroff I'm glad to see you recovered from your tragic car accident.
 
I love Justin Bieber. Because he looks like me.
 
@Pedro !!! The reports of your demise were wildly exaggerated (of course).
 
10:17 PM
awoken from the dead
 
@TedShifrin Well, I never said he died there.
 
There's a society at my university, I think it's some flavour of religion. They call themselves "Quakers" and dress in a style found in Robin Hood films from the 70s
 
There are Quakers in the US ... like in Massachusetts. Not sure where else they are.
 
They HATE gays, and I was sat there trying not to laugh at their views and they started really laying into them, really saying horrible things about how they anger god. Now .... religion in the UK is very mild compared to the Christian Middle East that is the US, so I asked the person next to me "I can't believe they'd say that, you think that's wrong right?" and I could tell that people were shocked....
It was weird, but me being the attention whore that I am, I stood up and said "Stop loathing gay people and let them teach you how to dress"
 
A lot of religious sects hate gays ... not to mention just good old bubbas.
 
10:20 PM
I was both sent out and given a round of applause.
 
LOL ... ok, 1 point for @Alec. But still, chill.
 
I hate religions that hate gays. I love gays.
 
So, @Pedro, you been off tennis-ing and avoiding math?
 
I think I am ten per cent gay, lol.
 
I'm thinking more, @Jasper, but I'm never good at accounting.
 
10:21 PM
[Read it? Good!]
 
@AlecTeal LOL
 
@Alec: Constantly deleting what you type is obnoxious.
 
[Read it? Good!]
 
There is no need to fear. You are safe here, lol.
 
Maybe you shouldn't say some of it, then.
 
10:23 PM
@TedShifrin I was giving classes.
 
Are your students ready to beat me love & love, @Pedro?
 
Started 09:45, finished 19:00.
Dunno how you play!
 
Wow ... that is a long day.
 
[You guessed it.]
 
Sometimes you talk too much @Alec.
And you're very much in love with yourself.
 
10:24 PM
I love Matt Damon, lol.
 
@MikeMiller What the hell.
 
Ryan gosling is hotter, @Jasper
 
@TedShifrin is.... I don't cry at my own reflection?
 
@MikeMiller No one can beat Oberyn.
 
lel
 
10:25 PM
Who's that guy that played Lucas from Spooks?
 
Well, technically he was beaten... but you know.
 
"full of gays"?
 
LOL
 
@Pedro: Rafa won #9.
I know you're shocked.
 
Dat mod wave.
 
10:26 PM
@Jasper.
 
@TedShifrin Yeah, it's ridiculous.
 
@KitFox Yes?
 
This is me looking at you sternly.
 
@KitFox a chat was a bit silly, there's not a problem here.
 
Hey people no flagging. You have to see it in perspective.
in English Language & Usage, Apr 25 at 9:32, by Jasper Loy
For example, I am not gay but I often dream of having sex with men.
 
10:27 PM
I know there's not a problem
 
@KitFox Are you punishing him for thinking Matt Damon is hotter than Ryan Gosling? Because that's certainly a valid reason.
 
But the rest of the network doesn't know that.
 
Oh good grief.
 
@RegDwigнt I didn't know the pattern, I thought he was just ....
Oh.
 
@MikeMiller as long as it's not Meth Damon...
 
10:28 PM
@TedShifrin Yes! Drama!
 
Whilst @Alec has erased everything he wrote ... uh huh.
 
I am an open guy, in fact I am studying bimodules at the moment.
 
slaps @Pedro stiffly
 
Some people study left or right modules. Separatists!
 
[Leave it be].
 
10:29 PM
@Jasper: (you can come out and play again)
 
I thought paranoia went out in my generation ... guess not.
 
@mixedmath Did you unban him?
 
@KitFox yes
 
@Pedro Heresy! Bourbaki decrees that modules only go one way!
 
@TedShifrin it's not paranoia, it's a search engine!
 
10:29 PM
I am sorry, I will be more conservative with my words from now. It's OK to ban me.
 
@mixedmath Thank you.
 
@KitFox It's OK to ban me, I accept it.
 
I'm tired of this nonsense. It's dinnertime.
 
Also I don't care that the NSA knows :P @JasperLoy STFU.
 
Nice to see you, @Pedro.
 
10:30 PM
You've not been banned, leave it at that.
Night @TedShifrin - I hope you were not joking earlier.
 
Joking?
 
@JasperLoy Just remember that this room isn't as cozy as ours.
 
@KitFox OK.
 
It's gotten downright ridiculous here ...
 
How do I link? :15978930 You said this.
 
10:31 PM
@TedShifrin Bye byes.
 
But, admittedly, there's been no math for 20 minutes.
 
Heyal
 
Heya @N3
 
Why is there a grownup blue guy here?
 
@TedShifrin Don't worry about things too much!
 
10:31 PM
Thanks @Pedro :P
 
@Ted That's not true, Pedro made a module joke.
 
Okay I have failed to quote @TedShifrin but you said
"Well, I despise Bieber, but I'm a faggot, so I take these things personally." - Ted Shifrin, earlier.
 
LOL @Mike ... yes, indeed
I was not lying ... and it's public record here, @Alec.
 
I don't know, I'm not your stalker!
 
...Is there an actual issue here?
 
10:32 PM
I don't know who you do!
 
@KitFox No!
=D
 
Hello @Ethan
 
If you were a cat instead, you'd be edible.
 
@KitFox Well, I think you should ban Pedro.
 
@JasperLoy hi
 
10:33 PM
Hi/bye @Ethan
 
hi
 
Geeze @MikeMiller leave him alone, you said he'd died in a car accident earlier.
 
@Ethan Is what we said in that chat recorded forever?
 
@JasperLoy yes.
 
@AlecTeal Not this chat, private chat between me and him, lol. Not on SE.
 
10:34 PM
@JasperLoy not really why?
 
@Ethan Just wondering. So nobody else can read what we said there?
 
@N3buchadnezzar Am I a grownup blue guy?
 
@Alec No, I just said the words "tragic car accident"; and I even said I wouldn't be at the (clearly non-existent!) funeral...
hello, @mixedmath, by the wy
 
@MikeMiller hiya
 
@MikeMiller What the hell.
 
10:37 PM
@Pedro I'm glad you recovered.
 
@Ethan Have you vanished?
 
@MikeMiller Do you call haircut car accidents? Mine went pretty well.
 
Post it again when ready, lol.
 
@N3 I liked it.
@Pedro I badly need a haircut myself.
 
Wait did that get flagged?
@N3buchadnezzar I did not see it.
 
10:40 PM
@MikeMiller ORLY.
 
Meh, it's hard to make the thingy rythme properly. syllable's and stuff ._.
 
@JasperLoy no i'm here, logs in the channels on freenode are deleted after a certain period of time
 
Yeah, I still dunno what a limerick is.
 
@JasperLoy and they aren't publically availble
 
@Ethan I see. I enjoyed our previous conversation, lol.
 
10:43 PM
@JasperLoy It's a five line poem with a particular rhyme scheme.
 
e.g. you would need like a warrant or something to get them (unless of course you had a bot in the channel keeping public logs, which there were none)
 
@Ethan I turned off gmail chat because I didn't want to mix email with chat.
 
@KitFox So, what do you like to read?
 
Nope, I am not. You can also just email me. I check it ten times a day, lol.
 
alright
 
10:49 PM
There once was a lad, Jasper Loy
a slightly sullen and timber boy
but a chatroom he found
and to people he bound
Please forget he sometimes annoy
I will leave it up for a minute or so =)
 
@N3buchadnezzar Thanks.
Why delete it?
 
Limerick. The syllables are 8,6,6,9,9. Could not make the first two and the last one of same width
 
@JasperLoy I heard that some ISP's block stuff in Singapore
 
By the way, who flagged me just now?
@Ethan Yes, mostly porn sites. But one can always use a VPN to access them, lol.
Not that I mind being flagged, but I don't understand why, lol.
@Ethan I don't know and I don't care, lol.
 
alright
 
10:53 PM
In Iran they even block Christian sites, lol.
 
@MikeMiller Books.
 
I like to watch scenes that are sapphic
with adult content that's graphic
they lead me to misuse
hand lotion and tissues
and build up my internet traffic
 
@N3buchadnezzar I am afraid that might get flagged, lol.
 
So Jasper talks about porn in this room, but about poo in ours. No fair.
 
>.< Found a few of these on a different site. This one were the nicest in the language. No profanities in my comments though =)
 
10:55 PM
@RegDwigнt Anyway if you really want that lego set, you could always come here for a holiday and get it!
 
@JasperLoy wait so you did see if after all?
Last thing I heard it sold out.
 
@RegDwigнt No, I did not see it, neither did I find out.
 
Hah.
Well, no lizards to kill for you then, either.
 
I almost never walk to the hotel area.
 
Some of these words need to be in a better order, but you get my point.
 
10:57 PM
Can someone help with tautology?
 
@RegDwigнt We should not talk about animals in this chat. Someone wanted me dead when I said I hate animals.
 
@NikolajKyed Math or linguistics?
 
Math
 
@NikolajKyed You should ask and not ask to ask.
 
I forgot all about math so I must pass.
 
10:58 PM
It's even in the subtitles of this room.
 
> Rarely if ever expressible as a ratio of integers.
Wut.
 
@RegDwigнt In otherwords, irrational, lol.
 
If I had statement forms A and B and must show that ~A v ~B is logically equivalent to A-> ~B
 
@JasperLoy Yes, but what is the antedecent.
 
A -> ~B
 
10:59 PM
That sentence just hangs around there with no connection.
You should at the very least swap it with the sentence before it.
 
@NikolajKyed Draw a truth table.
 
How exactly am I supposed to interpret the arrow? Is it just "implies"?
 
@NikolajKyed yes
 
So A is True, B is True, ~A is false and ~B is false, then A implying ~B is True?
 
@KitFox I can take a hint, but I won't. Who is an author you like?
 
11:03 PM
Oh yeah, since B is not B it's A.
 
Hey guys, anybody have any intuition for a non-induction proof of Sard's theorem?
Looking over Milnor's Topology From a Differentiable Viewpoint, want to understand Cobordism's
 
@RegDwigнt I think it's like 'Rarely, if ever, expressible...'
 
@NikolajKyed ---> ~B Means, if A is True Then ~ B is True.
If A is False Then ~A Holds.
Therefore, either ~A Holds or Else ~ B Holds.
Thus ~ A \/ ~ B Holds, where ~ A \/ ~ B Means "Not A or Not B"
---> ~B should be: A ---> ~B
 
@NikolajKyed the definition of P implies Q is: not P or Q
 
@Alraxite I'm not sure if I understand what you mean by "not P or Q"
 
11:13 PM
@NikolajKyed $\neg P \lor Q$
 
@Alraxite That's not what I meant. "the definition of P implies Q is: not P or Q". So P implying Q means it's not P nor Q?
 
@robjohn I think there I actually have $8$ parts. Anyway the problems is done, and I only need to type things in latex now ...
 
@NikolajKyed It was supposed to be interpreted as (not P) or Q.
 
I better take some sleep since I don't feel the keyboard anymore ...
 
loud hailstorm brrr
 
11:15 PM
@Alraxite Does that technically mean that it can either not be P or else it can be Q?
 
@NikolajKyed Yes, if your 'or' is the inclusive one.
 
@G.T.R let me create an integral for you before going to sleep ...
 
@Alraxite Alright I get it.
 
@Chris'ssis no I'm concerned with the storm at the moment :(
Damn it, my home is gonna get flooded if it keeps pouring like that :(((
 
@Alraxite How would you interpret: C -> (~($forall xC) v ~($exists xD))
 
11:21 PM
@G.T.R Evaluate in closed form $$\int_0^{\infty} \frac{x}{(e^x-1)(e^{x+\log\left(\sqrt{1+\sqrt{1+\sqrt{1+\cdots}}}\right)}-1)} \ dx$$
 
wonders which creek in Paris runs through @GTR's house
 
Newly created (of course)
 
@Ted it's raining like hell, I got some kind of "terrasse" with a "baie vitrée"
 
Ah, avec beaucoup de trous? ;)
Better put towels along the bottom of the doors.
 
@Ted oui c'est mal calfeutré.
 
11:29 PM
C'est un mot que je ne connais pas, mais je peux bien deviner
 
Kalfatert, if you know the German word, @Ted.
 
Leider nicht @DanielF
 
@NikolajKyed I find that hard to parse
 
Calibrated?
 
Oh Don Antonio got 100k as well.
 
11:32 PM
@NikolajKyed Well, the xD part. That's not funny.
 
There should be a celebration when I got 1k, lol.
 
@Alraxite I don't understand it either. Never seen it before
 
I've caught him in several errors, however, @Jasper.
 
@TedShifrin to caulk
 
Ahhh, of course. Thanks, @DanielF ... I barely know that word in English!
 
11:34 PM
@NikolajKyed I think it's like this, $C\implies \neg\forall x\;C \lor \exists D$, where presumably C and D are statements about x
 
@TedShifrin I had to look it up too. It's not in my active thesaurus.
 
@PedroTamaroff I upvoted your lhf!
 
Now @Pedro is stooping to lhf? Damn.
 
I wonder who lhf is and whether that is his real name.
 
@TedShifrin Explained notation. That's legit.
 
11:37 PM
@Alraxite I see. I'm trying to figure out that one as well. Because the question is to show that, that statement is logically equivalent to C -> (\forall xC -> ~(\exists xD)). Looking at this and then the previous one. Is it really any different in proof?
 
@NikolajKyed Uh, which statement?
 
On the front page of main, 40% of the questioners have rep $\le10$!!
 
@Alraxite Show that $C\implies \neg\forall x\;C \lor \exists D$ is logically equivalent to $C \implites (\forall xC \implits \neg(\exists xD))$
 
@NikolajKyed Call $\forall x C$ by P and $\exists x D$ by Q
 
@Alraxite So I essentially have the same case as previously?
 
11:47 PM
got that wrong.
You want to show $\neg P \lor Q$ is the same as $P \implies \neg Q$
which they are not
So.
@NikolajKyed they aren't equivalent.
Initially, for some reason I thought they were
 
@Alraxite But if the question specifically tells me to show that they are logically equivalent, then how would showing the opposite be correct?
 
@NikolajKyed Because it disproves the question's assumption that the statements are equivalent.
In other words, the question is wrong.
 
@Alraxite What excactly gives away that they're not equivalent?
 
@NikolajKyed The question asks to show $\neg P \lor Q$ is the same as $P\implies \neg Q$. But it actually is equivalent to $P \implies Q$
 
@Alraxite Does it have something to do with P implying ~Q, would be to imply that there $\forall xC$ there doesn't $\exist$ xD?
 
11:57 PM
@NikolajKyed So unless you were given a particular $D$ or you reproduced the question not carefully, the question is wrong.
 
@Alraxite I wasn't C and D are statementforms, I don't think that changes anything?
 
@DanielFischer you're usually superb at this, so I ask: I a question worth 6 marks (usually "state" = 2 marks, 3 at most!) for "State the exact definition of differentiability at $(0,0)$ for "$f:\mathbb{R}^2\rightarrow\mathbb{R}$" what does it want!?
6 whole marks!
 
@NikolajKyed Your expression doesn't make sense if C and D aren't statements
