8:00 AM
Well, you guys managed to see where I was while I was off... :)
 
@JM: Did you read the whole transcript for the time you were away? :D
 
@Skullpatrol Aw, you fixed it. I liked the original version!
 
@BrianMScott God does not play craps, but there is something strange going on with these prime numbers.
 
Which primes? Or just any old primes?
 
@JM I don't know who the real stalker is, but Asaf first posted that you were in the Mathematica site.
 
8:02 AM
@Srivatsan Something like that...
 
@BrianMScott You're right. I'm a bit slow. My original answer to exercise 37 was something like $G(\emptyset) = X$ and $G(n) = \bigcup G(n-1)$. Can I define $G$ in terms of $G$?
 
@JM I was looking for something I had said and found you here :-)
 
@JM Wat?! 0_o
 
@MattN Clearly you underestimate my abilities... :P
 
@BrianMScott Just any old prime numbers
 
8:04 AM
@JM Reading fast? Is that what you are talking about? =)
 
@JM Your Mathematica log is about to roll off the bottom.
 
Though I may have skipped a few lines on the ragequitting brouhaha. That wasn't fun to read...
 
@JM was that the QED log?
 
@JM You mean the QED thing? I missed the main part.
 
Well, yeah. Nasty business...
 
8:05 AM
@MattN What’s Definition 4(a)? It’ll take forever for that page to download.
 
@JM It came out that QED was suffering from clinical depression.
 
Oy. That’s no fun at all.
 
@BrianMScott $\bigcup^{(0)}x = x$ and $\bigcup^{(n+1)}x = \bigcup \left ( \bigcup^{(n)} x \right )$
 
@robjohn What's the source of this info?
Little birds?
 
@Srivatsan QED said that.
 
8:07 AM
Oh.
 
Oh boy, here we go.
 
@robjohn Ah, I see.
 
@JM I chewed off Yoda's head for his insults ...he had no right to push QED over the edge that way.
 
It was in the log that was quoted, but it seems to have been deleted now.
 
what's this QED story I keep hearing about?
 
8:08 AM
@Skullpatrol How are you so sure that it was completely yoda's fault? I for one, don't think y. did anything intentionally. I also think that the reaction from Q. was a bit surprising (i.e., it was a bit more extremely than I expected).
 
@Skullpatrol I read the logs; I did not find anything that yoda said very bad at all...
 
@robjohn He removed something immediately after he said it.
 
It didn't seem like yoda's fault, from my reading. In any event, it's not too easy to diagnose emotion from a few lines on a computer...
 
@JM Oh no. Not just that you can't diagnose emotions. More importantly, some of the offensive messages were cleaned up.
 
@Srivatsan I was in the room at the time.
 
8:09 AM
@MattN You want $G(F(0),\dots,F(n-1))=\bigcup F(n-1)$.
 
@BrianMScott But that would be defining $G$ in terms of $F$!
 
@Srivatsan Ah, so the transcript should have been longer? Yikes...
 
@Skullpatrol So? I was also in the room at that time. Except that I missed one crucial comment of y. that Q. claimed to be very offensive.
 
I hadn’t finished. That’s what you want $G$ to do for you. So the general rule must be $G(x_0,\dots,x_{n-1})=\bigcup x_{n-1}$.
 
@BrianMScott Oh. : )
 
8:11 AM
@JM And, it seems that since the mods cleaned it up, there won't even be the placeholder (removed) messages...
 
Better now? :-)
 
@Srivatsan QED said something like "you're the kind of person that makes me wish I was dead ... would you leave?"
 
@Skullpatrol Exactly my point. What did y. say that caused this reaction from Q.? As far as I can tell, none other than y. and Q. know.
 
BTW @rob: nice work on generalizing the Lucas-Fibonacci recursion. :)
 
The internet is a good place for escapism, but when even your online escapes fail to be as such, it can really grind on you.
3
 
8:13 AM
@BrianMScott Yes : ) But can I not define $G$ recursively? (If I correct the arguments it takes.)
 
@anon You seem to know a thing or two about the Internets.
 
@JM Ah, I thought that was the easiest way to get a sparse recursion. thanks
 
@Sri Something like that, I suppose.
 
@MattN I’d have to see what you have in mind. But I can’t see any good reason to do so.
 
Good morning.
 
8:14 AM
@Srivatsan QED and Yoda posted comments that they removed quickly ... and let me say that they were not nice
 
@anon And since nobody can see your face, and you can't see their's, it's easier for GIFT to happen...
3
 
@BrianMScott Well, what I wrote above: $G(n) = \bigcup G(n-1)$.
 
@Skullpatrol I can believe that. While I did see Q's comments, I missed y's one comment. The rest of y's comments seemed not-all-that-offensive to me. (But they are not addressed to me, so perhaps I was reading them lightly.)
 
@MattN That definitely can’t work, because the domain of $G$ has to be a set of finite sequences.
 
@Skullpatrol No comments on that.
 
8:16 AM
@JM Haha!
 
@BrianMScott I could add a sequence argument just to prevent the type error.
 
Show me what you have in mind.
 
@BrianMScott How about $G(\sigma, n) = \bigcup G(\sigma , n-1)$?
 
@Srivatsan Do you see how this option can be abused?
 
@BrianMScott Ah no. Having extra arguments is not allowed. : ,(
 
8:18 AM
@Skullpatrol No, I don't. How was it abused?
 
@Srivatsan You can say any thing and not be accountable for it.
 
@MattN No, because the domain of $G$ is finite sequences of sets related to $x$, not of natural numbers.
 
@BrianMScott Yes, I figured after writing it down.
 
@Skullpatrol, the same thing happens with comments on the main site
 
@Skullpatrol Which you could do in real life. At least you have a transcript and you can't delete a comment after 5 (maybe 2) minutes.
 
8:20 AM
if you edit, there is no record
 
Skullpatrol: You are asking for too much from the chatroom perhaps. =)
 
Perhaps ...
 
Thanks, Brian!
 
Any time!
 
Nice : )
 
8:25 AM
@robjohn How did it come out that QED was suffering from clinical depression?
 
@Skullpatrol It was in a log, from this room I believe, that seems to have been removed.
 
@robjohn Too much evidence is being "removed"
in my opinion.
 
...
 
(re my deleted message) Nevermind: I have a feeling this conversation isn't going to convince either party.
 
:3138440 (removed)
 
8:30 AM
This whole thread is gone: http://meta.stackoverflow.com/questions/118874/harassment-and-trolling-in-a-chat-room
 
@robjohn Who deleted it? Can someone check and tell?
 
@Srivatsan I don't believe that sort of info is publicly logged. Mods only, probably.
 
@Srivatsan I don't know how to tell
 
@robjohn You continue to surprise me: how did you locate a deleted post in a site you are not too active in (so don't have enough reps)?
 
It may have been removed at QED's request.
 
8:32 AM
@robjohn Pfft, I can't be bothered to get 10k on meta... :D
 
@Srivatsan I was reading the meta post and it is still in the history in my browser.
@JM :-p
 
@robjohn Hm, interesting tricks.
 
On the other hand, meta.math.SE is apparently now being held up as "fun reading"... ;)
Is our history really so tumultuous?
 
@JM fun? interesting
 
so much drama
 
8:36 AM
Ya. I can't believe I am part of it. In a small way... =)
 
I often see caveats of the form "...with the possible exception of Math, since they do things somewhat differently..."
 
we are special :D
look at MO
 
Good point, that.
 
What's MO got to do with this?
 
MO is specialer :)
 
8:38 AM
I think people at meta.SO have long accepted that MO is a complete outlier...
 
Math is in it's own .. prepares drum snares ... category.
 
@anon ouch
 
Did I hit you with the drum snare?
 
: D
 
8:42 AM
@anon What is a " drum snare"
 
Well crap. I thought those were the things you hit a drum with, but apparently not. Damn my musical vocabulary.
 
@anon So you meant drum "sticks"
 
@anon Damn, here I was imagining a funny scene... ;)
 
The snare drum or side drum is a melodic percussion instrument with strands of snares made of curled metal wire, metal cable, plastic cable, or gut cords stretched across the drumhead, typically the bottom. Pipe and tabor and some military snare drums often have a second set of snares on the bottom (internal) side of the top (batter) head to make a "brighter" sound. Different types can be found, like Piccolo snares, that have a smaller depth for a higher pitch, rope-tuned snares (Maracatoo snare) and the Brazilian "Tarol", that commonly has snares on the top of the upper drumhead. The snar...
 
uni, sweet uni
 
8:47 AM
@Ilya eww... uni
 
"Sweet"? You can eat it?
 
That time of the day when the chat messages convince you that you are better off asleep.
Bye guys!
 
@Srivatsan see ya!
 
@robjohn Did you know Dartmouth College forbids the use of the word University in its name?
 
8:51 AM
@Skullpatrol well it is not a university.
 
@JM Aren't you going to wish me sweet dreams? ;)
 
@Srivatsan sleep well ;-)
 
@robjohn Why isn't a University?
 
@Skullpatrol A university is a collection of colleges.
 
8:54 AM
@Srivatsan Fine. Sugary dreams. :)
(or aspartame dreams, if you prefer)
 
@JM dreams with aftertaste?
 
@robjohn That does sound interesting...
 
@JM Jaggery is what I prefer. Not sure you know what that means..
 
@Srivatsan Nope. Can you enlighten?
 
Jaggery (also transliterated as jaggeree) is a traditional unrefined non-centrifugal whole cane sugar consumed in Asia, Africa, Latin America, and the Caribbean. It is a concentrated product of cane juice without separation of the molasses and crystals, and can vary from golden brown to dark brown in color. It contains up to 50% sucrose, up to 20% invert sugars, moisture content of up to 20%, and the remainder made up of other insoluble matter such as wood ash, proteins and bagasse fibers. Origins and production Jaggery is made of the products of both sugarcane and the palm tree. The su...
 
8:56 AM
 
Oh, that's what it's called in English...
 
@robjohn What does that one penny coin do in front of the block of "Indian jaggery"? ;)
 
Apparently for scale purposes...
 
@Srivatsan size comparison?
 
Hm, perhaps. Yes, you're right, I guess.
 
8:57 AM
Ok. Going to uni to the library. You're all coming with me : ) See you in a bit.
 
Hello, guys.
 
@anon Who am I to disagree?
 
There are three mods here. I wonder if they have a mathematical formula telling them when something is going to happen here? :-)
 
I don't know; sometimes it feels like Lorenz's set of differential equations...
 
We keep going in loops, but if feels slightly different every time?
 
9:02 AM
And it eventually gets chaotic.
 
I've wrote some F# code :D
 
@Daniil What does it do?
 
@anon if it were the same each time, I would have to question our sanity.
@Daniil is that transposed C# code?
 
@JM nothing much; lazy fibonacci sequences, some standard higher-order functions, I've just started learning it
@robjohn almost :P
transposed to the new level of abstraction
 
@Daniil twere a musical joke
 
9:06 AM
@robjohn yeah, I know
I am actually going to play some piano later
do you play any instruments, @robjohn?
 
@Daniil I used to play the piano and the clarinet
I haven't played in years.
 
Clarinet sounds cool
 
Now I play boardgames. The fingering is much easier :-)
 
True; you can't play boardgames alone, though, can you?
 
@Daniil I guess it depends on the boardgame...
 
9:10 AM
Certainly Chutes and Ladders is no fun when played alone...
...and playing chess alone is complete nuts.
 
@JM Ah, but it is great practice
 
@robjohn Playing chess alone is great practice?
not against a computer of course...
 
@Skullpatrol yes. If you only play when there is someone else available, you don't get enough practice.
 
visualstudiogallery.msdn.microsoft.com/… - why have not I seen this before
 
@Skullpatrol I guess now that computer chess programs are available, you can play against them anytime.
 
9:14 AM
@JM: I presume you should be able to cast a delete vote here: math.stackexchange.com/a/102451/13425
 
Oh, I haven't checked the mod panel lately. Thanks for the nudge.
 
Did you? I am wondering if I could see your vote or not?
 
@robjohn I once read that more books have been written about the game of chess than all the other games combined.
 
@Skullpatrol I am not surprised.
 
Even including the fine game of Solitaire? =)
 
9:18 AM
@Srivatsan or Tic-Tac-Toe?
 
"Board games". You don't need a board for solitaire... ;)
 
@robjohn Hm, in fact, tic-tac-toe more sense than my example.
 
@Srivatsan I've cast a delete vote now.
 
@robjohn That is like saying Harvard has more books in its library than all the other ivy league universities/colleges combined.
 
@JM Hm, didn't know the context. :/
 
@JM Thanks. As I expected, I cannot see the vote.
BTW, @JM, what is your "helpful flags" count? See your profile page to find this.
 
Oh, that new thing? I'm glad they got rid of flag weight...
It says 162.
 
162!?
 
Eh? Why is that surprising?
 
@JM They should've assigned a moderator just to handle your flags. =)
 
9:23 AM
@Srivatsan There are now two.
 
@Skullpatrol how many books are in the Harvard library?
 
@Srivatsan Well, I'm clearly a long way off from "Marshal"; it can't be that bad... :)
 
@BrianMScott Thanks. I think I should beef up my rep to 20k now. Can't wait to get my teeth on those posts.
 
@robjohn I read once it is ten times bigger than the national average.
 
Speaking of rep: another sign that I've been away too long is that Brian's overtaken me... :)
 
9:25 AM
You mentioned that already. =)
 
I distinctly remember him being at the bottom of the rep page only a few weeks ago...
@Srivatsan I'm just stunned... :D
 
@JM Don't feel too bad. I've been here, but recently, my rep has pretty much stood still.
 
@robjohn What do you think of checkers as compared to chess?
 
mathoverflow.net/questions/7063/… this is really interesting
 
@Skullpatrol really? well, they use the same board.
 
9:38 AM
@robjohn half of the time
 
@Daniil Oh no! That is the issue that drove a huge wedge between Dave Seaman and me on sci.math.
He could not see that topology was at the root of the paradox
 
Sorry, I do not know who is Dave Seaman
 
I recognize the name from years ago when I was reading sci.math.
 
"This is how I justify buying mathematics books faster than I can read them. If I live forever, even though I keep buying them, I'll eventually read each one." My thoughts exactly.
4
 
Topology at the root of the paradox? I thought the paradox was just due to the ambiguous definition of the series
 
9:40 AM
@Daniil It's just one way to look at it...
 
@Daniil It is ambiguous because the topology has not been defined, so convergence cannot be established.
 
I don't know much about topology, but can you elaborate? Topology has not been defined where?
 
Or in some statements of the problem, the topology of pointwise convergence is implicitly assumed.
 
@robjohn, I like your analysis of the problem.
To back up a bit for @Daniil's benefit, whenever one speaks of what happens "in the limit", one is implicitly speaking in topological terms.
 
@RahulNarain Thanks for taking up the slack while I was gone :-)
 
9:51 AM
@robjohn: My pleasure, but now @Daniil is silent :-(
 
@Daniil The topology of pointwise convergence says that a sequence of function $f_n$ converges to $f$ if for each $x$, $f_n(x)\to f(x)$.
 
@RahulNarain sorry, I was AFK
@RahulNarain oh, I think I don't know that much about topology
I thought that topology = a collection of open sets in topological space
 
In most statements of the problem, $f_n$ maps a ball to which bin it is in at stage $n$
 
@robjohn but.. there is only one bin, innit?
 
@Daniil no, the function maps each ball to the bin it's in
 
9:55 AM
Well, I am not sure what problem are you talking about, because in the original statement there is only one urn.
 
@Daniil: A topology is indeed a collection of open sets, but the notion of open sets is intimately connected with limits.
If I give you a sequence of elements of an arbitrary set, how can you say whether it converges?
 
since the range of $f_n$ is discrete (isomorphic to $\mathbb{Z}$) convergence can only occur if $f_n(x)$ is eventually constant (for $n>N(x)$).
 
@robjohn, it definitely looks to me like you're talking about a slightly different problem.
 
@RahulNarain Hmm. Let me read that one again.
 
@RahulNarain sequence converges to $x_0$ if for every $\epsilon$-neighbourhood there exist a $n$ such as for all $i>n$, $x_i \in$ the neighbourhood.
 
10:00 AM
@RahulNarain Ah, okay, so the range of $f_n$ is $\{\text{in},\text{out}\}$
 
There is only one urn in the linked problem. But I guess you can define $f_n(x)$ to be either 0 or 1 depending on whether ball $x$ is in the urn at time $n$ or not.
 
@robjohn ah, I see
 
Simulpost!
 
@robjohn No, it’s $\{\text{in},\text{out}\}^\omega$.
 
@Daniil So $f_n$ looks like $\text{in},\text{in},\text{out},\text{in},\dots$
 
10:03 AM
@BrianMScott why? Each ball can be either in or out.
 
@BrianMScott No, the values of $f_n(x)$ are $\text{in}$ or $\text{out}$...
 
That’s exactly why: the value of $f_n$ is a sequence.
 
@Daniil: Yes, that works if your set is a metric space. But you don't really need the full structure of a metric space. If all you have is a topology, just replace "$\epsilon$-neighborhood of $x$" with "open set containing $x$" and the definition works just fine.
 
@BrianMScott The domain of $f_n$ is $\mathbb{Z}$ and the range is $\{\text{in},\text{out}\}$
 
@Daniil: And if you do have a metric space, you automatically have a topology, with open sets formed by the open balls under the metric.
 
10:06 AM
@robjohn Eh, you’re right; I was thinking of the function $f:\omega\to\{\text{in},\text{out}\}^\omega$.
 
@BrianMScott Yes, if you include $n$ as an argument...
 
@Daniil: So the essential thing you need to talk about limits and convergence is nothing but a topology.
 
@RahulNarain Yes, and I argued this until I was blue in the face, but Dave Seaman would never agree that topology was even involved.
 
Whoever deleted my comment on the drama thread disambiguating myself from BD should delete Eric Naslund's comment as well, which still accuses DB (me) of sockpuppetry.
 
@DanBrumleve I think there is too much deletion-of-comments going on right now.
 
10:09 AM
never had a comment deleted before
 
@robjohn: Perhaps he didn't agree that the question was about limits? I don't know if that's a sound position to hold at all, but maybe...
 
i don't want a casual reader to get the wrong impression that I am the subject of drama just because i offered my opinion there.
that's why i posted my comment in the first place
 
With all of these ins and outs I’m reminded of the classic description of cricket: Cricket is a game in which there are 2 sides – one out on the field, and the other in.

Each man in the side that is in goes out, and when he is out he comes in, then the next man goes out until he’s out and then he comes in.

When the side that is in is all out, the side that has been out goes in, and the side that was in goes out and tries to get out the side that went in.

Sometimes there are men still in and not out when the side that is in is finally out.
 
@Dan, someone's fixed the bold text to say "you are BD", but the other instances of "DB" remain.
 
rahul yes
 
10:11 AM
@RahulNarain Yes, but the whole description he held about which balls were still in at 12:00 was that a ball was in the bin if it was in the bin from some point on. That is exactly the topology of pointwise convergence.
 
that thread is tired and i won't post there again. hope a mod sees my plea on chat at least.
 
@DanBrumleve Is that the one started by Math Gems?
 
@robjohn Ah, well, I didn't say it was necessarily a sound position. You have my sympathies.
 
yeah
i am really a nice guy and i'd like to remain known that way
too few credentials to really butt heads with anyone here
 
Can’t imagine why anyone would remove your comment. It wasn’t just harmless: it was useful.
 
10:15 AM
@DanBrumleve I'm a really nasty person, as you can see by my gravatar :-)
 
I read that thread earlier today; my reaction was that Math Gems couldn’t have generated more sympathy for the moderators if he’d wanted to.
 
sympathy all around
the point i tried to make is that the policy is wrong
everyone gets banished after a few years
 
@robjohn Have you ever thought of adding a dangling root, untimely ripped from the ground?
 
@BrianMScott I tried to find some way to add a root into the avatar, but nothing looked good.
 
(x-i)(x+1/2+i/2)(x-1/2+i/2) = 0?
 
10:18 AM
@Ilya They have moved me to another room.
HB04.280.
 
@robjohn Too bad. Though I will say that the present version has a certain spare elegance.
 
@robjohn I liked the candy cane look.
 
@BrianMScott I wanted it to be extremely simple.
 
@DanBrumleve, you could flag something and ask that Eric's comment be amended. I remember one of the mods saying on Meta that flagging an arbitrary thing is an acceptable way to get their attention.
 
ahh flag
thanks
 
10:20 AM
@JonasTeuwen Is that a room, or a Library of Congress classification?!
 
rude or offensive
 
Well, maybe not that.
 
@RahulNarain thank you, I got it :)
 
even aside from misidentifying BD, it is.
 
I hate shaving :(
 
10:22 AM
@Daniil Then don't.
 
@DanBrumleve If you flag a question or answer, you get the opportunity to write something you want to say to the mods. I don't know if that happens if you flag comments.
 
@Daniil I’m not terribly fond of it myself, so I haven’t for many, many years.
 
@BrianMScott HB means "hoogbouw" which means high building and 04 is the floor and 230 is the room :-).
I should also add the faculty but I didn't switch that so Ilya still knows how to find me.
 
@BrianMScott I haven't since the end of high school.
 
it didn't give me a dialogue but i guess rude or offensive is the point
 
10:23 AM
I had to for a while: I was drafted in 1969 and served in 1970-1.
 
@BrianMScott you probably have a good beard
 
@JonasTeuwen Hoogbouw I’d have understood, but I’d certainly not have guessed it from HB.
 
@robjohn wow, I am requesting a picture!
 
@Daniil Pretty small, actually: I trim it pretty regularly. You can see a not particularly good picture here.
 
@BrianMScott Oh, of course not. It is an abbreviation for a lot of things.
 
10:24 AM
shaving is bad for the skin
women like it though
 
I'm not manly enough to have a full beard.
 
i couldn't get one til i was 30
 
Five more unmanly years!
 
@BrianMScott nice :D
 
@Daniil I have trimmed, but not shaved, so it is not long.
 
10:27 AM
i'm telling you chicks dig it shaved
 
Do they want a man or not? 8-).
 
well find the right girl maybe
 
How about that barber who only shaves men who do not shave themselves ... what does his "beard" look like?
 
having a beard feels awesome though
 
@Fortuon: I just approved that tag edit.
 
10:30 AM
@JM: I saw this question on your profile, so I added an answer :-)
 
I think females are people too and they might have different views on different things.
4
 
@Skullpatrol Trick question. The barber is a woman.
 
hah!
oops didn't mean to go there
limited personal experience is all
 
@robjohn Cool! But I still like my general answer... :D
 
@RahulNarain So the woman barber does not shave herself?
 
10:32 AM
@Skullpatrol Nope. She only shaves men who do not shave themselves.
 
skullpatrol a falsehood implies everything
 
@RahulNarain You got me on the gender point ;-)
 
@robjohn A nice one, too.
 
@BrianMScott If Math Gems wanted sympathy, that was certainly the backwards way to go about it...
 
Yep. And Math Gem’s responses in the comments just made it worse and worse.
 
10:35 AM
@RahulNarain What if she only shaves people who do not shave themselves?
 
again that entire thread deserves some sympathy
victims of policy all of us
i guess that's what makes SE work
 
Speaking of beards... I can't even grow a damn goatee... :(
So I just shave...
 
@Skullpatrol that kind of barber does not exist
 
@Daniil Ding ding ding! We have a winner.
 
@Daniil Just like my name on Santa Claus's list ;-)
 
10:37 AM
I took the train from Wisconsin out to California at the beginning of my freshman year, and one of the conductors told my that I looked like a 13-year old with a beard. I was 17, but he was probably right. I didn’t grow a good one until just after the army.
 
@RahulNarain yeah, it's a pretty banal thing :/
I used to have a beard which made me look like Jesus.
But I have no photo evidence of that.
 
@BrianMScott What? Why did he tell you that? :D.
 
Most of my life I’ve looked younger than my actual age. In this case the scraggly beard probably just accentuated the impression.
 
@Daniil "banal" indeed
 
yeah skipping grades made me feel that way too
also going to work as a teenager
these days i'm average age average looks
 
10:42 AM
@BrianMScott I'd kill to look younger than my age...
 
prefer it that way
 
@BrianMScott Ah, thank you Brian. Sorry, I was dazed.
 
@JM I don’t think that I do anymore, though some of my students last year still seemed to think so. I think that they were judging by actions rather than looks.
@FortuonPaendrag You’re welcome.
 
@JM Doesn't the lack of beard do that already? 8-).
 
@JM I remember long ago noting that for odd $n$, $e^{inx}-e^{-inx}$ was a combination of odd powers of $e^{ix}-e^{-ix}$.
 
10:43 AM
@JonasTeuwen Not if you have white hair. :)
 
You have hair? :-) Mine keeps slipping backwards.
 
@robjohn Oh, right. The elementary functions are rich in identities... still amazed, even when I know them.
 
@JM and so I do like your answer, but not only for that reason :-)
 
@BrianMScott Well, there hasn't been a case of alopecia in the clan, but you never know...
 
No alopecia here either, but I do lose a lot of hair. Well, maybe it is still within normal regions.

(FWIW, it's been a decade since I switched shampoo brands...)
 
I generally just buy whatever’s cheapest.
 
So do I 8-).
Maybe that's what explains the alopecia... ;-).
 
I should qualify that: as long as the advertised fragrance doesn’t sound too noxious.

It's Asaf time!
 
@Daniil Is there any difference with "hammer time"?
 
DUN DUN DUNNNN!!!!
 
@JM Asaf time is much better :D
 
@AsafKaragila Give him some credit: he did use the (homework) tag. So I gave him an answer.
 
What is the friction between the boat and the water?

@DanBrumleve $\aleph_2$.
 
@AsafKaragila That's really sticky water...
 
Asaf, do you have a beard?
 
It's not my fault.
 
Maybe it’s the boat that’s sticky. Or maybe what floats Asaf’s boat is mucilage.
 
Not a big beard, but I'm not shaving (at best trimming it from time to time)

@BrianMScott How heavy is the anchor?
 
I don't have a boat.
 
@robjohn It’s probably a rowboat without an anchor.
 
I hate the sea, the ocean, etc etc. I am a big fan of dead and dreaded areas like the desert (and probably the tundra as well).
 
@BrianMScott assumption?
 
Tundra’s too cold.
@robjohn Sure, why not? We’re mathematicians: we’re allowed to make assumptions.
