3:09 PM
Damn, then I don't know why my palms are hairy and I need contacts.
 
@Chris'ssis here
 
@KarlKronenfeld well, but now at least you know how to fix not knowing it!
 
@RegDwigнt Thanks for your contribution...
 
Any time.
 
@robjohn Clever. It seems you successfully used Gautschi's inequalty in some proofs.
 
3:12 PM
@Chris'ssis It is not a useless inequality
 
I remember that I saw it before in some other proofs.
@robjohn actually it's proving to be pretty useful.
 
@RegDwigнt Ah, I was gone for a bit. Was the prior comment flagged?
 
@robjohn no! Skull right there summoned me manually...
 
@RegDwigнt Okay. I hadn't seen you here before, so I wondered about all that :-)
 
Hey now. I have posted totally valuable stuff before.
May 31 '12 at 12:54, by RegDwight ΒВBẞ8
You have not studied mathematics to google stuff for people.
May 31 '12 at 12:54, by RegDwight ΒВBẞ8
That's what you study physics for.
See. So useful.
 
3:16 PM
A mod?
What happened?
 
Where?
 
Someone gone berserk? Anything fun?
@RegDwigнt Well, you.
 
Well, scroll up.
 
Not sure if I am just stupid, but I cannot figure out this hint. The idea seems to be that one should prove $A+I/I$ is Noetherian. Not sure how...
 
@PedroTamaroff then wait till you notice robjohn.
The mod density immediately doubles.
Just like that.
 
3:17 PM
You look like an hippo on acid.
 
That's a hippo where I come from. Who are you, the Queen?
 
@RegDwigнt I have a problem with "h"s. In fact, I am having a headache at the moment.
They haunt me.
 
No acid that I can see.
 
@KarlKronenfeld Cannot help. I just happened to start reading about modules today.
@RegDwigнt Look at the eyes.
 
@PedroTamaroff I think I figured out an alternative proof. No worries. :)
 
3:19 PM
@PedroTamaroff then don't look at the crocodile.
 
@RegDwigнt That's not acid. That guy is totally stoned.
Melting down.
 
Yes, all my animals take different drugs.
Hold on, Heisenberg customer incoming.
 
That's clear, yes.
 
@RegDwigнt I take you have a door bell. You don't want anyone knocking.
 
3:20 PM
Crystal blue persuasion.
 
@RegDwigнt Do you make those?
 
@PedroTamaroff I meant the mountain goat.
 
@RegDwigнt Aren't all goats from the mountain?
 
@PedroTamaroff yes I make those. And soon enough LEGO will be making those. You can vote for it, then they'll be making them faster.
 
@RegDwigнt Yeah, you got my vote.
Though I am more of a Star Wars LEGO fan. Those look nice.
@RegDwigнt How many animals are there in the set?
 
3:23 PM
It is up to you to decide. When voting for the project, you'll be asked how much you'd be willing to pay for such a set. LEGO then takes the prices the people enter and calculates from there how large the set should be.
 
Oh, I wanted it to be the other way around.
It asks how much I'd pay, but that depends on the size of the set.
 
Of course. It's easier for them this way.
 
We've reached an impasse.
Damn.
 
But we can calculate that. How many different animals do you want to have in total?
Like, just the hippo, or five other ones, or an advent calendar with 24 different ones.
 
Well, for six animals I guess one can pay... 15 bucks? I don't know about the size. Maybe it can go up to 20?
 
3:25 PM
Going by the parts count, each animal will be like four bucks.
So for six, you could enter 20 and be fine.
 
Ah, so I kinda underpriced it. LEGOs are pretty expensive.
"How many such products would you buy?"
 
CUUSOO projects even more so, because they are limited, and with higher-quality boxes and instructions.
@PedroTamaroff yeah another stupid question. Everyone just enters 1 there, obviously. Unless you have ten grandchildren and don't want any of them to be missing out.
 
@robjohn btw, did you get a closed form for the $1$st integral I posted some hours ago?
 
@RegDwigнt You know, I once bought an X-fighter, and lost a piece. When I filed a thingy to LEGO to get the pieces back, I mistakenly clicked to option the pieces were missing. They sent them all the way from Denmark to my place, here in Argentina. BANANAS.
 
LEGO will send you anything and everything for free, as long as you are being honest.
Their support is spectacular beyond belief.
 
3:29 PM
Yeah.
I couldn't believe it.
lego.cuusoo.com/ideas/view/25 SIGH on the ballistas, @RegDwigнt
 
@PedroTamaroff I tried avogadro's number there. They didn't accept it so I have to lie. grrr
 
That's a nice project. Even though a bit too many CUUSOO projects so far are about space.
But it's a great build.
There are lots and lots of excellent projects on there.
Especially now that they have done some pruning and got rid of thousands of subpar projects.
 
Does CUUSOO stand for anything?
 
It's Japanese for something like "wish to come into existence" or some such.
There might be others in this room more qualified to answer, I don't speak enough Japanese.
The original site was only in Japanese and only for the Japanese market. The first two projects only got released in Japan. A Japanese submarine, and a Japanese satellite.
 
I miss the medieval LEGO sets.-
 
3:34 PM
Well they still have the line, just under a different name.
 
I had the biggest one of this set when I was younger, eventually it got lost and the base broke down.
 
!!lego 7189
 
@PedroTamaroff they still have the huge castles, too. With dragons, even.
!!lego 70404
 
3:35 PM
This one!
Not that one.
Sigh.
6090.
 
500 mint in sealed box after all these years is a bargain.
There are sets that run in the thousands after just a couple years.
There are individual parts that cost 100+ bucks apiece.
 
WAT.
Why?
 
Because rare.
 
Ha.
The pieces I have now have gotten a little greenish, I think. The grey ones, say, look more grey-green now.
Wonder if they preserve them somehow.
 
This one in grey only comes in one set, and that one set happens to be the Millenium Falcon, Collector's Edition.
As a result, the one part costs 125 bucks.
@PedroTamaroff don't let them catch sunlight. Simple as that.
 
3:41 PM
This is amazing.
Have you seen the guy that made the Japanese warship?
 
White and old grey are the two colors most susceptible to yellowing over time if exposed to sunlight.
You can reverse the reaction with hydrogen hyperoxide, though I never tried myself.
 
@RegDwigнt Hm, good to know.
 
@PedroTamaroff that has nothing on the Serenity model that one dude built.
 
The Millenium Falcon is like $1000 right?
 
3:43 PM
$4000
ERMAGHERD.
 
Yeah I was going to say that.
Café Corner will soon be there as well. And Greengrocer.
 
@RegDwigнt What's that?
@RegDwigнt Why are they so expensive?
@RegDwigнt Heh, 70k pieces must cost...
 
Because demand and supply, that's why.
 
@PedroTamaroff, $$\max_{x_1}f(x_1,g(x_1)).$$ And, let $f$ attends max at $x_1^*$, so first order necessary conditions imply that $$\dfrac{\partial f(x_1^*,g(x_1^*))}{\partial x_1}+\dfrac{\partial f(x_1^*,g(x_1^*))}{\partial x_2}\dfrac{d g(x_1^*)}{dx_1}$$ as well as first order necessary conditions imply that $$\dfrac{\partial f(x_1^*,g(x_1^*))}{\partial x_1}=0$$ and $$\dfrac{\partial f(x_1^*,g(x_1^*))}{\partial x_2}=0.$$
 
@PedroTamaroff in bley? Not that much. $3500.
 
3:45 PM
@RegDwigнt So 0,05 a piece?
 
Depends on which pieces you need.
 
my text says "If the differential function $f(x_1,\dots,x_n)$ reaches a local interior maximum at $(x_1^*,\dots,x_n^*)$, then these hold simultaneously: $$\dfrac{\partial f(x_1^*,\dots,x_n^*)}{\partial x_1}=0;\dots;\dfrac{\partial f(x_1^*,\dots,x_n^*)}{\partial x_n}=0 $$
 
(Look, I can do math!)
@Sush Aha. What's the problem?
@RegDwigнt Sure.
 
@PedroTamaroff that's the asking price for the most common pieces, yes. As pointed out above, for more rare ones it goes all the way up to 150 dollars, though.
!!lego 10182
 
3:46 PM
That's Café Corner
The first modular building.
Worth a couple thousand now.
 
@PedroTamaroff, am I right in calculations? Robjohn said I am not.
 
@RegDwigнt Heh, WOW. But I take it then it is cheaper to have some skills and just buy the pieces yourself and have a blast. =P
 
@PedroTamaroff except some of the pieces needed for that set are only in that set.
 
@RegDwigнt Yeah, that I assumed.
 
The arch in dark blue alone goes for 20 dollars.
Other pieces used to be more common, but have since been discontinued.
 
3:48 PM
And I take it you cannot exploit the "I lost that part" system. =)
 
They introduce 500 new pieces every year, and retire just as many old ones.
@PedroTamaroff I suppose you could get away with pretending not to have one part, or even five, but for this you'll be missing like 200, 400, 600.
 
@PedroTamaroff, robjohn said $\dfrac{\partial f(x_1^*,g(x_1^*))}{\partial x_1}=0$ and $\dfrac{\partial f(x_1^*,g(x_1^*))}{\partial x_2}=0.$ do not hold. Why so?
 
@RegDwigнt Right. My point above.
@Sush You need to use the chain rule, I guess.
 
The set has 2040 parts. I have a collection of roughly 180,000 parts, and I'm specifically collecting as many different parts in as many different colors as possible, and yet I am still missing 75 parts for that set, or almost 4%.
Even if I completely ignore colors, I'm still missing 10.
 
@RegDwigнt Woah, you're a serious LEGO fan.
 
3:52 PM
You could say that, yes.
But for every fish there's an even bigger fish.
 
Wonders if there's a name for that.
@RegDwigнt So, you know a bunch of languages?
 
Yeah. Where'd you read that?
 
I could play with it, but just read your top question on ELU.
 
You probably mean answer.
 
Yep. =)
 
3:54 PM
My top question is some MC bait.
Oh wait, no. My top question is actually solid.
 
MC bait?
 
It surpassed the MC bait recently due to making the rounds on Reddit.
 
What does MC bait mean?
 
@PedroTamaroff MultiCollider bait. The MultiCollider is that thingamajig with the top questions network-wide that used to be a dropdown in the top left corner of every page, and is now an embedded list on the right of some pages.
 
Ah, they steal Q&A from us, yes.
 
3:56 PM
Basically due to how the algorigthm works, only soft questions ever get there.
So if you ask about some Riemann shit, nobody will care. But if you ask "wut iz favrity math movie lol", then it will get there in no time.
 
@RegDwigнt Did not know that.
 
MC bait, then, is just such questions asked on purpose, to get views or upvotes or hats or badges or whatever it is you are after right now.
 
Don't you find the use of language in mathematics interesting?
 
I find the usage of language in everything interesting.
 
Well, just meant "particularly".
 
3:58 PM
Yeah I know, yet still.
And don't forget about the use of mathematics in language.
 
@RegDwigнt Oh, but that is not a happy going.
They misuse words.
Say, "exponentially" gets dropped down daily.
"There's been an exponential increase in..."
 
A word may have more than one meaning. Most words in most languages do.
 
Aha.
French or German?
 
French or German what?
 
If you had to choose one of those.
 
4:02 PM
I could cheat and choose another romance language instead of French. There's no shortage of those.
So that makes the choice easy.
 
I mean, if you had to choose strictly between those two...?
 
Depends on the situation.
 
Explain?
 
But I guess if you check by rep on FL and my rep on GL you'll have your answer.
@PedroTamaroff well if you're locked up in la Bastille, no amount of German will help you outta there.
So I'd take French, thank you.
 
@RegDwigнt Ha! Agreed.
 
4:04 PM
But if you happen to be buying bread in Berlin, French is of like no use at all.
 
@RegDwigнt ¬.¬
 
And I might add that I find myself buying bread in Berlin more often than being locked up in la Bastille. Not that I'm complaining.
But YMMV, is what I'm saying.
 
OK, that acronym beats me.
 
your mileage may vary
 
I'm trying to decide if I should learn German or French to read mathematics.
 
4:06 PM
french
 
I'd learn German only to read Landau.
 
if you have even the vaguest of interests in doing algebraic geometry, french
 
@Mike Spanish being my mothertongue, I feel French shouldn't be as tough as German.
 
@N3buchadnezzar I just created a new double integral you might love ...
 
@Mike GAGA.
 
4:07 PM
@Mike but German if you have even the vaguest of interests in doing anything else.
 
Meh
 
See.
 
You really don't need to learn other languages
 
@Mike I have been told to read Bourbaki's Topology.
 
They're all very easily readable without the slightest bit of knowledge.
 
4:08 PM
I have Willard with me.
 
@Mike That's like saying you really don't need to learn maths because you already know how to eat spaghetti.
There's more than one thing to life.
 
I agree that learning a language is a beautiful thing worthy of its own pursuit
 
@Mike вен рид вис фор ми притти плиз.
 
But if your only interest is in using it to read math papers, then it's an overstated need.
 
I am pretty satisfied with my English, but German or French seem way more elegant.
English seems more mundane.
 
4:09 PM
@Mike but that's a constraint you yourself slapped on a posteriori. You're cheating.
 
@Mike Well, that's just an excuse.
 
@Red
 
Besides, what if the language happens to be so beautiful you want to expand and read poetry in it? And more to the point, what if it's so hideous that you don't?
But I must be taking my leave soon.
Must go buy some LEGO.
 
@Red Take a look at my profile. I agree. :P
 
So many people keep calling me Red. Hint: Redinald is not a name.
 
4:12 PM
@RegDwigнt Reginald. Heh.
 
Yes. The ruler.
And not the one you beat math pupils with.
 
I've only just woken up, I blame my grogginess.
 
@N3buchadnezzar here is the beauty $$\int_0^1 \int_0^1 \int_0^1 \left(\left\lfloor \frac{z y}{x}\right \rfloor -z \left \lfloor \frac{y}{x}\right \rfloor\right) \ dx \ dy \ dz $$
 
@RegDwigнt Physical violence? That's so last century.
Nowadays there's mind torment.
"Calculus 101". OK, kids, open page 10 of Rudin's Principles. We will construct the reals.
 
I dunno, have you been to a secret CIA prison as of late?
 
4:14 PM
@RegDwigнt I was talking math classes.
 
Of course not, only the public ones.
 
@PedroTamaroff same difference.
@Mike that is the correct answer.
 
@RegDwigнt It is interesting how you used the words "same" and "difference" like that. Hmm...
 
It's interesting that you find it interesting. Outside of this chatroom it's idiomatic, and has been forever.
 
Only a significant period of time, not quite forever.
 
4:18 PM
"Forever" is certainly a big word.
 
No, it's only seven letters.
 
HA-HA-HA.
 
@Mike see, you fall right into the trap again.
18 mins ago, by RegDwigнt
A word may have more than one meaning. Most words in most languages do.
 
You'll make me break a rib.
 
@Mike it is only two letters. Seven would be itttttt.
 
4:19 PM
I like unorthodox.
 
Of course you do, you're a sinner.
 
Is there a God of the Words? What am I getting into here?
 
@Chris'ssis this one?
 
@robjohn yeah.
 
4:24 PM
@Chris'ssis Just found it...
 
Well, it's been fun, but now it's commie mutant time.
Ouvert et haut !
 
@robjohn great!
 
@RegDwigнt Adiós.
 
@robjohn there I found an awesome proof.
 
4:53 PM
@Pedro One of those answers has the same problem you're pointing out. He says "we need to find a G..."
 
5:20 PM
@Mike Ah?
 
On the thing you linked as "Ze details"
 
"Yes we can." I am inspired.
Was that Obama's line?
 
@Mike That's quite far-fetched.
 
@pedro What are you studying these days?
 
5:28 PM
@JasperLoy Algebra and Measure Theory. Trying to. =)
 
@PedroTamaroff Measure Theory from where?
 
@JasperLoy Well it is actually "Integral, Measure, Derivative. A unified approach" from Shilov and Gurevich.
 
@PedroTamaroff Ah, I have never seen that book.
 
The last part concerning derivatives is bananas.
 
The last chapter of baby Rudin is also measure theory.
 
5:30 PM
Yep. I could take a peek at that.
 
The undergrad paper I wrote is also measure theory, lol.
 
Ah, Fancy Pansy Jasper.
 
@Sush Masturbation does not cause hair loss, and is not a bad thing. Don't worry about it. Don't listen to those who tell you otherwise.
 
@rschwieb I like the av
 
@Mike Hi! Thanks :) Hopefully the artist doesn't chase me down...
 
leo
5:40 PM
@Sush aren't good desires?
math can cause loss of hair
 
Mental illness can cause hair loss.
Hi @charlie.
 
Hi @jasper
 
leo
when one is studying, tend to rest on your hand grabbing your forehead
then hair loss
 
Or radiation
 
@leo I don't think it works that way, lol.
 
5:44 PM
Lol of vitamins
Lack Damn it
 
leo
@JasperLoy like this:
 
@leo Is that you?
 
leo
yes
 
Haha, first time I see.
 
leo
he he
 
5:48 PM
Not me }:)
 
leo
he he
I have those entries
by 28 I'll be bald
 
Just get married by then, lol.
 
leo
ha ha ha
 
@leo "This is forehead of security"
 
leo
I think I'll get married at 40 or so
 
5:50 PM
naah
 
leo
would be hard without hair
 
I won't get married this life.
 
leo
hurry hurry
 
sorry, I'm just one
 
Why so few lhf these days?
 
5:53 PM
who knows
maybe the OP's are masturbating
 
Geezis.
 
what @jasper ?
 
@Charlie Nothing.
 
natgeo is so cool
the only good thing on tv lately
 
What is natgeo?
 
5:56 PM
national geographic
 
leo
@Charlie don't you like history channel?
 
aliens!
 
leo
@MickLH yeah
this guy with the crazy hair
 
the one who's not saying it's aliens.. but....?
 
Hey guys, i have a short question: if $f:\mathb R\to \mathbb R$ is continuous and bijective, can you follow for f that the image of open sets is always open? a yes or no would be enough. thanks.
 
leo
6:07 PM
@user31035 yes because $f^{-1}$ is continuous
@MickLH this guy:
 
Hahaha
 
leo
6:24 PM
there are more idiots than what one can imagine
 
6:41 PM
Definitely @leo
