2:00 AM
Oh, darn. Really? (I guess I should have asked whether n was real or integral)
 
are you allowed to do n + -> 2?
 
anyway, got it
 
Actually I specified 'n staying natural'
 
Oh that's what you meant, right sorry
 
I got a stupid answer
 
2:00 AM
@GarethMcCaughan It's not trivial, is it?
 
You guys are good.
 
there was a puzzle on PSE not so long ago based on a closely related theorem, I think
 
(lim {n}^sqrt n->infinity 1)+2 = 3
does that count? @Wen
 
It might've been my puzzle...
 
2:01 AM
oh, maybe it was
 
Actually I don't think I ever posted it here
 
no, doesn't look like it was yours
I vaguely thought Rand got in with the answer first, but I don't see it in his recent answers
 
@boboquack I don't think so. I mean, the answer doesn't even look true at first glance
How recent was this?
 
Last few months, I thought. But my sense of time is really crap.
hint for Wen's formulanagram: it's closely related to the second one he posted
 
@Wen I think it does work:
 
2:10 AM
the limit is undefined
because Wen already said that in this formula {} denotes fractional part
and there is no sequence of integers n for which n^frac(n) -> oo
 
Okay, it works, but what I meant was that the answer isn't supposed to look true.
 
@GarethMcCaughan but it's frac(sqrt(n))
so taking n=k^2-1 for k=1,2,3,... will do the trick
 
oh, duh, can't read
anyway, actual answer to Wen's is lim {(2+sqrt(3))^n}=1 which is true because (2+sqrt(3))^n + (2-sqrt(3))^n is always an integer, and the second term is small and positive
 
I think that last one was neat
 
2:14 AM
what should I do?
It looks like the answer is already stated in the question
 
Doesn't everyone love typing out control characters by hand: %7bn%5e%7b%5c%7b%5csqrt%7bn%7d%5c%7d%7d%5c?
 
I have no idea what that does.
 
they're URL-encoding escapes for unusual characters. E.g., %7B means character 0x7B which is a left curly brace. Not sure what boboquack is doing that requires braces to be escaped in this way.
 
nice
(another one with a cute proof)
oh, wait, though
 
2:21 AM
Oh no, I'm missing something aren't I
 
if it's what I think it is, are you sure you aren't one minus sign short? [EDITED: not any more!]
 
@GarethMcCaughan that's an excerpt from https://a-ta.co/mathjax/%5cleft(%5cdisplaystyle%5clim_%7bn%5e%7b%5c%7b%5csqrt%7‌​bn%7d%5c%7d%7d%5crightarrow%5cinfty%7d1%5cright)+2=3.svg, the link to my earlier cook of Wen's anagram
 
@boboquack so why were you typing the escapes by hand?
 
the background of those images shouldn't be transparent
a-ta.co images are unreadable in dark chat
 
@GarethMcCaughan because otherwise it didn't work
 
2:22 AM
but you can type them not by hand
 
@ffao you can click on the link and remove .svg I think
 
too much work to see a single formula
 
actually, you don't need to remove .svg
 
I can't seem to be able to recall any maths formulas without operations/terms that will completely give them away
 
@ffao this better?
or would you prefer a different colour?
 
2:25 AM
That looks like it would be hard to read
 
I think a different colour would be better
 
much better
 
a little better
 
Let's try something that I found lying around
btw, do I have to have proved the formula is true?
 
2:28 AM
@ffao ^^^^^ that?
 
that's a lot better for me but would probably be obnoxious for others :P
 
yep :P
 
@boboquack hotdog.vim
 
@Wen1now btw this was not the formula I was on about
Somebody's got to have gotten this one by now
 
(sorry, was doing other things. yes, that one's clear enough)
(but going to bed now -- it's ~3.30am local time)
 
2:36 AM
Okay, good night
 
night
@Wen1now what is it
 
thats pretty cool
1*2*3=1+2+3
 
Wait what?
 
1*2*3=1+2+3
solved
 
2:45 AM
what is the other one
 
1+2+3=1*2*3
3*2*1=1+3+2
 
2:57 AM
(26-2)/(3+5)*2=7
 
We can swap digits around, right?
 
yes
ohh dear
I made a mistake it would seem
sorry
the five should be a four
(26-2)/(3+4)*2=7
be warned, this one is specifically designed to trip you up
 
I haven't been following
What's the goal here?
 
to find the anagram of the expression which evaluates true
 
put the divide over the equals
:P
 
3:04 AM
:P
 
36/(2*2)+(2-4)=7
 
yes, and there is at least one more
 
Wait, wait. The goal is to anagram to an interesting formula
 
I re-found my original
should I post it
 
this is interesting
I was doing formula anagrams just yesterday
we managed to use all but seven of our fridge magnets
 
3:11 AM
That actually sounds like a good idea
I'm trying to recall other interesting formulae
 
how do you generate the math equations
 
@stacksfiller :| but you used a 7 for a 1
 
We also used a 4 for a A, and an M for a Sigma, and an 8 for an Infinity, etc.
the 7 and 1 swap is probably the most similar if im being real!
the angle in the 7 and the 1 is the exact same!
 
still seems obvious though
 
3:21 AM
@stacksfiller :|
 
must be quadratic formula
@ASCII-only That was the fun of it!
Also, we dont really have summation or subset magnets obviously
so our formulas would have been a lot more boring without some creativity
 
wait :| you have no equals magnets
 
(since you'd need two | to make an = sign)
 
these aren't math magnets, they're just a-zA-Z0-9
The subset is a U the plus is an x
etc.
that's odd
why do I say "a U" and "an x"
when U is a vowel and x is a consonant
 
'U' starts with a y sound. 'X' starts with an 'e' sound
 
3:25 AM
@GarethMcCaughan @micsthepick ctrl+k is a thing on SE chat
 
def f(x):
    pass
@ASCII-only indeed it is
 
why do people base64 encode their a-ta.co things?
 
because it's at the bottom of the page (also the image source)
 
Isn't it the default?
 
3:27 AM
^
 
wait, you don't have to handcraft the url?
 
And I've been handcrafting it all this time
 
1 hour ago, by Gareth McCaughan
@boboquack so why were you typing the escapes by hand?
^That actually makes sense now
 
3:32 AM
Surely by now...
Did anyone look at my latest equation?
 
I have a solution but it's not what you were going for
integral from 1 to 1 of exdx = x-x
 
well go ahead
 
(i don't know how to make the picture)
Wait wouldn't you need a C anyway
oh wait no, that's if there aren't numbers on the integral
Yeah my solution works, just very cheaty :P
 
I wouldn't change the fraction bar to a minus sign :P
easy to fix though
@stacksfiller now try and solve it.
1 LQP and SE to review, but I don't have enough rep
 
I'm trying but all I keep getting is
xd Sex
and somehow i don't think that's on the right track
 
3:48 AM
> xd
 
it's like XD but when youre not laughing hard enough to use uppercase
 
@stacksfiller what does that even mean though
 
Sid
How do you get Sex there?
 
integral e x
or Tinder
depending on what you meant by that question ;)
 
I probably messed up badly too:
 
3:51 AM
e^1-1 = 2x/2x ^ 2
 
what
 
cause e^0 = 1
 
missing some brackets
 
oh I missed some fraction bars too
but seems like that should be an easy method to get it
something like 2/x / 2/x or whatever
so e ^ 1^1 - 1^2 = 2/x / 2/x
that's my answer
 
:| what
 
3:53 AM
e ^ (1^1 - 1^2) = (2/x)/(2/x)
 
I don't understand how the rules of anagramming formulas work
 
i dont know how people are making the images
 
25 mins ago, by ASCII-only
@boboquack https://a-ta.co/generator/
 
but that answer should work, right?
 
@ffao anagramming?
 
3:54 AM
when it's text it's simple enough, but how do you deal with superscripts, subscripts, fraction bars
 
@ffao how to deal when
if you mean latex -> text then a bunch of parens to group everything correctly
@stacksfiller relevant
 
lmao
 
3:58 AM
haha
 
how do I inline the images from the generator
 
doesn't really make any sense though
@micsthepick You'd have to have something going after the d
(like me ;) )
(sorry i had to)
 
@EricTressler I think it has to be in it's own post. No idea though
 
@ffao as long as each symbol is there and nothing else it is a valid anagram?
 
4:04 AM
@stacksfiller :| nil?
 
@stacksfiller you should put parens somewhere
 
Is * times?
 
4:07 AM
@Wen1now yes
because some people don't want to type \times i guess
 
or don't know it's a thing like me
 
-1 This question does not show any research effort
 
4:20 AM
I thought my one would be fairly obvious
 
Which one?
I can see bunches of pictures but can't tell which are puzzles, solutions or jokes

I think I got taht
Although calculus really is not one of my strong points
 
boom
got it
 
sigh
 
4:24 AM
Clever
 
well, @stacksfiller it appears you have outwitted me once again.
 
@stacksfiller is the 1000*1000 thing a question?
 
that was the answer to the one above it
 
but seriously, what do you think it was supposed to be wen?
 
integrating 1/x gives log(x)
take that to the power of e
And you get x
(with a few minor touches)
 
4:27 AM
+1 intended answer
but not expressed well...
 
Hmmm. I'd've had e oustide the integral part. Not sure if it gives the same answer though
I think it does though
 
what is the upper bound of your integral?
 
x
As in e^(integral)=x
 
that also works then yes
e^ln(u) = ln(e^u) = u for u > 0
so not for all x
so really you weren't quite there I guess :(

Close enough...

Q: Ripple effects: A suite of puzzles and conundrums

Wen1nowPuzzles I was wrapped up in making ripple effects back in the day so here are some: Yellow squares are a number from 1-5. Also, the puzzles are disjoint (e.g each grid is its own puzzle), so I guess you can post partials if you solve, say, 1 puzzle I guess. There was going to be a...

Q: Fill in the two missing places

eedrahI've written down some numbers. There are two missing places which need to be filled in. There should not be ambiguity - the missing places have a unique solution. What are the missing numbers? And what is the meaning behind all the numbers? 5 1 7 2 2 1 3 1 5 0 3 0 6 1 3 2 7 2 4 2 7 ? ? 5

 
@Wen so the 8 is an 8 in your puzzle and not a 1?
 
Yeah
 
and are all the other green numbers weird too?

Hi
The green numbers are normal
 
OK
 
7:29 AM
@Sphinx Is this not pure math?
 
Sid
@Deusovi remember I was telling about a cryptic hunt in my uni?
You would have been horrified at the poor excuse of puzzles that are here.
 
Wow, was it that bad?
 
Sid
@Deusovi they gave a 9-letter "word" and we had to get a name from that. Obvious we had to anagram 9 letters to get some name which in the end isn't even a famous name.
 
Is it at least a name relevant to your university?
Did anyone get it? That sounds awful.
 
Sid
@Deusovi nope. Random name
Even Google shows a spelling error if you google that name..
 
7:43 AM
ha!
that's hilarious
 
Sid
@Deusovi they had to reveal the answer in the end. Pretty sure, no one got it..
 
so, that basically guarantees that there was absolutely no testsolving
 
Sid
Yep. Initially, the puzzles weren't too bad. But, as it progressed, they become exponentially worse

I've got a puzzle hunt horror story of my own, from my university
 
Sid
7:50 AM
@Deusovi ...wow. care to share?
 
As for the puzzles, I could say a lot about their issues...

So at the start of the hunt, we were given a transparency and a booklet.

The booklet had a lot of things related to various puzzles, a map of campus with a grid, and a section of fake ads.
Problem 1: One of those fake ads led directly to the end of the hunt (which was to call a certain phone number on a sign).
 
Sid
@Deusovi ...what? Hunt ends before it starts?
 
Call to arms: We're all being baffled in Spyfall as the wily spy attempts to hide! Join for some fun!
 
We didn't go there, because we were too busy trying to solve all the regular puzzles as fast as possible. (And we didn't know at the time it was the meta solution. There were two red herrings, too, but they were ridiculously far away - in the corners of the map, nowhere near the actual site of the hunt. The three winning teams all found the sign early and called it as soon as the meta clue was revealed.)
Which leads me to problem #2: Solving the regular puzzles quickly was pointless. The meta clue was given out to everyone at the same time. I was the first to solve all six component puzzles, then I waited around playing games on my phone for 45 minutes while several other teams caught up.
 
That's Deus all right! :P
 
7:55 AM
They weren't exactly difficult puzzles. I'm sure anyone here could've solved them in about the same amount of time.
 
hallu
 
Hey! I'm just telling everyone the story of the awful puzzle hunt I went to about a year ago.
 
Sid
Hey @edderiofer
 
Oh yes, I recall that.
 
Sid
And I am telling Deus about the terrible hunt I am at, right now. :P
 
7:59 AM
Ooh dear.
When you're done, can I tell you all the story of the awful ARG (henceforth known as the ARGH) I attended?
 
"The meta clue was given out to everyone at the same time", why? D:
I can't see how anyone thought this was a good idea
 
oh yes, the ARG-H was funny
I don't know why either. Anyway:
The component puzzles varied drastically in difficulty and interesting-ness.

- One used the transparency twice. There was a sheet of paper on a bench: covering it with the transparency would circle some letters, spelling out "LOOK FAMILIAR?". Doing the same, but to the poster used to advertise the hunt, would spell "THE ANSWER IS 92".

(Unfortunately, that poster was taken down from almost everywhere, and I had to ask the organizers where a copy would be.)
So already, we can see the poor planning. They took down an integral component of a puzzle from nearly everywhere before the hunt started.
- We walked up to someone who told us to hold out our hands, palm-up. He put a sticker of a sundae on them. (Subtle.) In our instruction book was... well, I'll show you.
Going to the actual pool table inside, we saw those symbols taped to the pockets. Inside the triangle pocket (the symbol by "Palm Sundae") was the 2-ball, so the answer was 2.
So far, not particularly interesting or challenging, but not offensively bad. But it got worse.
- The next puzzle was a rebus puzzle. Pretty standard small hunt fare. We walked into a classroom, and taped to the seats were pictures. There were two in each row, and always an empty seat in between. They spelled words when you added a letter in between (DISC _ EDIT --> DISCREDIT). Then the inserted letters spelled out "ONE HUNDRED"... when you randomly anagrammed them.
We didn't get that at first, because it almost spelled out words (with the ones we were missing).
But nope! We were just supposed to anagram, apparently.
- There was the sudoku puzzle. We got a 4x4 sudoku grid (labelled "Top Shelf Sudoku"). It only had two clues in it, and four question marks in the centre squares.

The map also had four question marks, so we went there and had numbers clued to us using images.

(IV drip represented 4, basketball going through hoop represented 2 (points)...)
Solving the Sudoku and literally just taking the top row gave us "4213".
That one wasn't interesting, but I would like to note that the advertising specifically said the puzzles WEREN'T Sudoku. That was one of the examples of puzzles you supposedly WOULD
 
o nooooooo
 
- The next puzzle was the "Cacophony". This was the best puzzle out of the whole thing (though that's not saying much). There were three speakers playing different songs, organized with two images in between.
Organized like:

(speaker) 9 To 5
(picture) clocks
(speaker) 8 Days A Week
(picture) chasm
(speaker) Mambo #5

The clocks were "times" and the chasm was "divided", so these clued 925×8÷5, which gave us the number 1480.
- And finally, the worst f---ing puzzle out of them all (besides the meta): The Roman Race. We walked up to someone who made us participate in a race. It was pretty short, the results didn't matter, and because he wanted to "mix things up" he had us "wheelbarrow" one leg of it (only 15-20 metres, or something around that amount).
We got no clues for finishing.
Turns out the path we took was all that was important. It was an XI (with the I sort of "joined" to the X), so the answer was 11.
That is, unless you looked at it from any other angle.
In which case it was either an IX,x̅, or x̲. (Or even 4.)
That's right, there was ambiguity in the actual solution to one of the puzzles.
The only thing disambiguating was the "answer bank" used for the metapuzzle. It had a ton of random phrases listed next to numbers, and there was no number 9 on it. (There were a lot of other numbers skipped, too - after all, it did go up to 4213.)
So, it was a useless race that made my hands hurt like hell, leading to an ambiguous final clue.

And finally, the metapuzzle. Back in that area where we found the sudoku pictures, there was a letter Q taped to a tree. The meta clue was to go to that area and look for a letter. (I had already found it.) Going to Q4 (since it was in a square with
So any team who had stumbled across it could win instantly after the meta clue was released. (Unless they had poor vision and couldn't see the coordinates on the tag, in which case they had literally no way to solve the puzzle.) Also, the entire "metapuzzle" was just a race to random points on the map - no actual puzzles, just following instructions.
And of course, the fact that I was first to finish the six component puzzles meant nothing. I didn't win anything from that hunt. Other teams had called the number first.
 
Yep, horrible.
By the way, Deusovi, I've put a new puzzle into the Patzers Club Puzzle Collection. You might want to try it. >:D
 
8:16 AM
(Also, for the race, the sidewalk was one of those that had rocks "fused" into it, and I had to walk on my hands while my teammate carried my legs - any only because the organizer running that puzzle was bored.)
 
eugh
 
like that, kinda
 
Ouch.
 
Sid
@Deusovi ...i feel your pain. That is horrible
 
Next year, that university will have you run a marathon on your hands, on broken glass, to get an E. Or maybe an M, 3, or W, who knows.
(But if you take the shortcut, then you actually get an I instead. Or maybe it's a /.
 
8:19 AM
About a month ago, they held applications for helping create the hunt. I was rejected, even though I'm pretty sure I'm the only one with actual puzzle-creating experience on campus (besides them, if you count those as "actual puzzles"). (Or the only one who applied, at least.)
 
PFFFFFFFF
 
ouch, they didn't make us do things as bad as that in my university's military training
that's ridiculous
 
Anyway, that's the story of the puzzle hunt where the speed of your running (rather than solving) is what mattered for the prizes - the only puzzle hunt that has caused me physical pain to solve (which I later found out was entirely unnecessary).
 
Yep, that makes the story of the ARGH pale heavily in comparison.
 
reminds me of an episode of the last season of The Amazing Race where they did all of the usual challenges to end having to take a train a couple of hours later to the pit stop
and all of the positions were decided by who ran out of the train faster
such a terrible leg
 
8:27 AM
pff
that sounds pretty similar to my experience
 
bunching is a common problem, but usually they have the contestants take trains/planes/etc at the very start so that it doesn't influence that much, or at least you'd think they would have learned to do that in the 28th season
luckily it was redeemed because the immediately following episode was a really good leg (if only because of location, since they were doing challenges atop the Alps), so it got much better from there
the story of the ARGH is at least already funny just because of the name
even though I don't know what actually happened in it
 
@edderiofer, you're up for bad puzzle stories.
 
Alright.
So I was on this server where someone decided to run an ARG.
(It wasn't actually an ARG since there wasn't anything physical; it was more of an online puzzlehunt.)
So the guy basically posted two overused riddles (whose answers were CANDLE and SECRET), and told us there were three more clues online.
(This server was tied to a certain website known for piracy of a certain videogame series.)
 
(An ARG is an "alternate reality game", a puzzle hunt-ish thing meant to be solved by a large community as a whole. The puzzles are typically all based around a story - for instance, one puzzle might give you the username and password to "hack into" a website, where you can read emails between some of the main characters relevant to the plot.)
 
Fair enough, the ARG didn't even have a story.
 
8:39 AM
that was more meant to be a general introduction, since not everyone will have heard of ARGs before. anyway, carry on
 
Anyway, when I submitted the answers CANDLE and SECRET to the guy, he said:

"Both right! Here are the clues: Gi, De"
And looking at the website showed "Clue #3: RRI", implying there were two other clues.
But I scoured the website, and couldn't find a thing.
So after a while, the organizer said "Oh right, you might have to look in other places related to the site." So I checked the external links on the site's homepage, nothing.
It took ages before I thought of checking the site's unused forums before I found "Clue #1: DAS"
(Apologies, Clue #3 was actually RRI.)
As for Clue #2? It was on the Steam Group for that site. Which again, nobody ever uses.
 
(Fixed for you.)
 
Thanks.
OK, so I got all five parts of the answer in chunks, clearly this is a chunked anagram. So I'll throw "<(de)(gi)(rri)(das)(pai)>" into Nutrimatic and-- Oh, nothing?
Maybe it's a full-on anagram then (though that seems unlikely given the letters being all chunked up like this). I'll throw "degirridaspai" into Anagram-Solver.Net and-- Nothing again?!
The guy revealed that it was the name of a song.
To which I replied:
"For all I know, the song could be called "Rigid Paradise" or "Gadi Disrepair" or "Irid Aga Spider"."
And to which *he* replied:

". . . wow you litterally just said the answer."
So there you have it. That one time I solved an anagram by sheer luck.
 
Touhou? I like this guy
 
(Nutrimatic gives it as one of the 6 options, by the way.)
 
8:50 AM
Anyway, he sends me then to this server with 12 more puzzles.
 
oh god
 
The last puzzle is the medieval riddle "No-legs lay on one-leg,two legs sat near on three legs,four legs got some.", and at that point I know that this guy can't tell a good puzzle from a bad one.
 
(that's from The Hobbit, not medieval)
(...and it's intentionally bad)
 
The other 11 puzzles involve extracting a single digit from a bunch of images with captions.
As an example: i.imgur.com/G4PAeqP.png
Note that that image was taken straight from DeviantArt and, as far as I'm aware, was not modified.
And then when I complain about the low quality of the puzzles to the rest of the server, he has this smug holier-than-thou attitude of "I'm a beginner, therefore any shit I create should be good!".
He said: "You do realize I was pretty much on my own on this right? No help, no prior experience with this? I could only make something that seems intuitive to me, because that's all I've got."
 
Sid
@edderiofer that is a wonderful excuse...
 
8:56 AM
Except he never posted in the #puzzle-games channel of that server before. Had he done so, I would have gladly helped him out.
So in short, that excuse just doesn't hold up.
 
what is the answer to the puzzle in the image?
 
I have literally no idea.
 
come on, it was intuitive
 
Well, I had a discussion about this with a different group I'm in, and we settled on the conclusion that the one digit we should extract is this one: 🖕
 
when you told us about it, we thought it was 9. "Minecraft" sounds kinda like 9 if you don't think about it too much, and it also has 9 letters
 
8:59 AM
But then why the picture of it being a Scarlet Devil Mansion from Touhou? That's got no relation.
