Q: Why does the natural log still exist?

cool_noiceSo I was thinking the other day in my Swedish residence in Ikea, Sweden, "Why does e^ln(-2) = -2???" Because ln (-2) is undefined and I can't do e^undefined so why does it equal -2? I was thinking, did man make a mistake in inventing its system of mathematics? I think I would like to propose some...

 
This guy has an odd fascination with Sweden lol
> "Why does e^ln(-2) = -2???" Because ln (-2) is undefined and I can't do e^undefined so why does it equal -2?
1. Because of complex numbers
2. If complex numbers didn't exist, e^ln(-2) _wouldn't_ be -2
3. wtf
 
I mean, in a way, complex numbers don't exist. They're not real, are they? ;)
 
Well, that reminds me of the pun I was gonna make before HN deleted this:
@NewPosts Because if it didn't, that'd be totally unnatural
 
4:43 PM
I love how this user's only badge (as of when I last checked) is... Informed.
 
@RadvylfPrograms You don't need complex numbers to find this confusion. If 1/(1/x) = x, then 1/(1/0) = 0, but 1/0 is undefined?!?1
 
A lot of first questions get deleted
@pxeger That's different though, since 1/(1/0) isn't 0, and 1/0 actually is undefined
 
In fact, it occurs with any invertible partial function
 
@DLosc Though, given how unsuited the tour page is for how we use the site, maybe reading it leads to more off-base questions...
 
4:46 PM
Well this user's obviously trolling

lmao i got my comment flagged for harassment/bigotry/abuse
okay
 
god will smite you if you delete or downvote this. i am a priest so i speak to god and ahlahl and all other gods. and zeus. so don't do my friend. in your best interest — cool_noice 1 min ago
 
@pxeger I would like to know the context to this.
 
But can we get more flags and downvotes on codegolf.stackexchange.com/a/246235/79857
@pxeger Context? It's random nonsense.
There's nothing to really read into, this is either AI generated or a random combination of sentences a human typed for the express purpose of being random.

don't take that out of context
 
I love how when we get spam and trolls and stuff it gets quickly taken care of but we all thoroughly enjoy it lol

well it's easy to suppress it either way; might as well have some fun rather than suffering :P
 
ye
be a waste of a good laugh
 
4:55 PM
they tried
 
HN is big brother confirmed
 
I'm gonna be the sixth marshal at this rate
 
> rapant evil cia dealings
Canadian CIA agent censoring the Swedes :p
> hyper neutrino i think thats one of those things in CERN
 
oh I get it now
 
Is this supposed to be an insult or something...I don't think the guy realized that HN is named after a particle lol
 
4:57 PM
I was trying to work out what that meant
I was interpreting "hyper neutrino" to be in vocative
 
ya know what
I'm tempted to just destroy the account lol
 
@RadvylfPrograms darn I was almost done with my sarcastic comment to this effect
 
@hyper-neutrino suspend, surely?
 
@hyper-neutrino we're gonna have to... reeducate you.
 
right but the account seems to have been created to post spam/nonsense and has no positive participation which is one of the destruction reasons kekw
 
5:00 PM
They've sort of posted an answer, the loophole violating one, but I don't think they have any plans to be a productive member of the community lol
 
> the deep state has spread that far. god is doomed
Didn't realize the deep state was able to commit deicide :P
 
Isn't the whole point of God that deicide is impossible?
 
Unless you have clay soldiers
 
I'm imagining some texan redneck trying to figure out how to use SE
(no offense Radvylf)
 
@RadvylfPrograms Or an infinitely tall tower. One in Babylon, maybe.
 
5:03 PM
 
@pxeger Depends, I guess. The poster previously mentioned "all other gods. and zeus." So presumably some of those gods could be killed (like Balder for example).
 
@RadvylfPrograms (note: the site this comes from is pretty NSFW)
 
good thing I can't see it then
 
@RadvylfPrograms what, external-preview.redd.it?
lol
 
5:20 PM
Look at my new gold badge!
 
@pxeger Well, nothing in the Tower of Babel account says that the people were interested in killing God. Their stated goals are 1) building a city, 2) building a tower with its top in the heavens, 3) making a name for themselves, and 4) not being scattered across the earth. What exactly is the underlying significance of those goals is a matter of some scholarly debate, IIRC.
 
@mathcat Nice!
 
@NewPosts I am happy this got deleted but I'm kinda also amused by this person
Who has the time to write (at least) 2 long posts just to troll others?
 
Exactly the sort of thing I'd enjoy doing
Heck it's exactly what I do in school sometimes
Mr. Riggs doesn't actually read any of our assignments, I turned in a planning document for ispshor instead of a persuasive essay and still got a 100
So I just write random nonsense sometimes for the fun of it
and turn that in
 
@RadvylfPrograms Oh no, is there a troll hidden in you waiting to be released?
We should preemptively destroy your account just to be on the safe side
 
5:33 PM
Quite possibly, but I'm not going to fall to the dark side any time soon
 
That's what Anakin said too
 
@DLosc Well, you can't kill God without getting to him, right?
 
Sure you can, just fire a missile
I guess they didn't have missiles back then but the concept of long-range killing probably existed
@RadvylfPrograms I have to ask, are you looking at this site at school?
 
@user No lol
 
Ah. I mentally inserted the word "how" into that question
 
5:38 PM
Even early-xkcd-Randall-Munroe classifies it as NSFW
 
Asking you guys how you do anything is not of much use, I don't get any of that server stuff
@RadvylfPrograms Don't tell me, there's an xkcd with a flowchart for this?
 
Ah
This would be much more fun than any math I've ever done
@NewPosts Because God isn't good at math
Hmm, maybe submitting a link to the OEIS sequence should be a valid output method for sequence challenges (SMBC)
I should probably stop reading comics now
 
6:49 PM
Who's gonna get #13000?
 
After some thought, I think it might be possible to create an anonymous recursive function in tinylisp
 
7:04 PM
was (lambda (x) (x x)) (lambda (x) (x x)) not good enough?
 
@pxeger ohoh
this is good enough, innit?
 
@pxeger Issue is, there's no closures or nonlexical scoping...

Q: Pair my brackets

mathcatGiven a string consisting of ()[]{}, print the paired brackets in the same order as they appear in the string. Any opening bracket ([{ can be paired with any closing bracket )]}. For example: ({()[}]] returns: (], {], (), [} Rules A string consisting of ()[]{} should be received as the input Th...

 
yay
 
I'd like to be able to do a lambda that takes itself
I love that the -3's still in there
 
7:13 PM
@allxy You could make a Z combinator and use that maybe
If a Y combinator is imossible
 
Tinylisp has lexical scoping so function arguments are only accessible in the function they're in
 
the Z combinator is recursive
 
Can you still do a Y combinator with that limit?
 
@allxy Why does what I wrote not work with lexical scoping?
 
It does
 
7:17 PM
(lambda (arg1_ arg2_)
    ((lambda (x) (x x))
    (lambda (self arg1 arg2) (
        ; any recursive computation - to recurse, just call `self`
)) arg1_ arg2_))
 
That's what I was thinking of too
 
but that uses closures
 
But the third lambda can't access arg1_ and arg2_
ninja'd
Hmm... partial application might be possible...
 
are there any global variables or something that you can use to emulate closures?
 
You can define stuff but we're trying to avoid that
 
7:20 PM
can you use some q and v hackery?
 
Actually, maybe...
If you recursively go through the function as a list replacing arg1 and arg2 with their actual values... maybe?
 
> recursively
and how are you planning to do that, exactly?
 
With a named function recursive-replace?
Doesn't even need to be named actually
 
oh, you're allowing definitions for utilities?
 
Someone in my latin class found the teacher's edition of our textbook
With the answer key
 
7:25 PM
Yeah, since this function that generates self-recursive functions has to be named anyway.
 
> Every teacher's edition book is on wish.com
- me
 
Actually... how do I do a tail-recursive deep replace?
 
I don't think it can be tail-recursive
 
That's annoying
 
That's not really a problem, is it?
It will just be slightly slow
 
7:29 PM
Kinda is
IIRC the recursion limit's 50
 
Oh
It should be possible to make breadthwise recursion tail-recursive, even if depthwise can't be
If you just write a simple tail-recursive map function, and use that where possible
 
That already exists - (load library)
15 hours ago, by allxy
I'm just going to make a fmap that calls the function with its extra (all but first two) arguments and each element.
But I need to do that first because closuren't
 
@pxeger Yes, but if you make a named Z combinator once, you can reuse it for anonymous functions that cheat at being recursive later
 
But those functions have the same problem
They can't access their arguments
@allxy Is this even possible? :|
 
@pxeger Just in case Redwolf has had a similar idea to me, which is possible given the hints he's given, I'm going to leave a sha256 of a summary of my language's premise here: 9b8b9fff7dc6e44ed146415d81ae82c1018018d3843ec941923df2cce5514d88
Because I want to patent it ;)
 
7:42 PM
Hm yes, very useful.
 
I'll do the same, then
(hashes end up being the same :p)
 
do you mean nonunique? lol
 
e215dd68ce99428346edc55c43d611447a6aba824fe8df8b6b3c90f31ea9d8a2
I wouldn't be surprised if the ideas were similar
@pxeger If you generate an RSA keypair with openssl or similar, I can send you a brief summary of catstruct (if you promise not to reveal any details about it)
 
Will a GPG key do?
 
7:54 PM
Available on all good keyservers™ as C0F860435983AEF7E9FC7CACC34505B6413390DE
 
I find it kinda hilarious that you're going through all of this when you could just email nevergonnagiveyouup@pxeger.com
Wait did that ping?
 
no
email would be fine honestly lol

xxd of file.gpg
idk if that's how I'm supposed to do it but whatever
 
Yep, that worked
 
cryptography ftw
 
8:00 PM
Well, it's not the same
 
How close are they?
 
The underlying premise, not very
But I still think the resulting encoding might be similar, based on how you've described it
 
Interesting
catstruct probably won't be implemented for a few months, but I've got an operator list and stuff planned
I'm thinking it could actually be competitive with the top golfing languages, although I only get 75% as many operators
 
stoopid chip shortages
 
ikr, the packets they give these days are like 60% air instead of the old 50%
And there isn't enough salt :(
Pringles is still good tho
 
8:06 PM
.-.
when you want a Jetson Nano but they haven't been in stock for 5 months
 
I always mix up Jetson with Jensen, and then think NVIDIA named their product after their own CEO
 
they're selling for like $500 on ebay
 
"Introducing the Jensen Nano, your very own voodoo doll of our amazing CEO!"
 
@RadvylfPrograms If you send me your key, I'll send you an explanation of mine too if you're curious
 
I'm curious
 
8:08 PM
This exchange of yours has street drug dealer vibes
 
(but my name is ginger)
 
We should do a hostile takeover of TNB where all messages are encrypted so noone else knows what we're talking about
 
._.
how about you do not
> Gisfh
hmmmmmmm
 
@RadvylfPrograms thinking about it a bit more, we might be able to combine our two ideas and join forces to make an even more unnecessarily complicated competitive language
 
@RadvylfPrograms I'm really interested now... :(
 
8:11 PM
oh god
the world is not ready for that
and then you can implement it in makina

As I've said many times before, it's really easy to design a language that can beat all but six jelly answers - simply remove °
 
Sure, but it's rather cheaty to use a log_256(255) byte codepage
 
@RadvylfPrograms is gpg -a what you want?
 
yes it seems
catstruct will have either a bit or byte mode
-B and -b respectively
 
8:14 PM
catstruct is clunky, you should call it kittybuild
 
I made a new room so we don't fill TNB with meaningless (to everyone else) encrypted messages
 
Huh, that's pretty cool
 
Thank you lol
It's hard to use though
 
How is "a therefore b" translated into propositional logic
 
a:1->b:1
 
8:26 PM
right that's what i thought too but my friend's midterm solutions apparently say that it's a ∧ b
 
wait really? that's just how I would express that
apparently I guessed correctly
 
well no I'm not sure cuz like
I agree with you, but I've been told it's ∧ (AND) which... sounds entirely wrong to me but
 
 
9:26 PM
i guess it might be like
the phrasing of "a therefore b" could actually be read as something to the effect of "b is true if a is true, and a is true"
i.e. (a -> b) ∧ a
then modus ponens from there
still feels wrong though lmao
 
hmmmmm
the specific one here was "if i eat bacon i get fat, therefore i eat cereal"
 
like for starters that's pretty much useless
 
using p as "eat bacon", q as "become fat", r as "eat cereal" the solution says it should be (p → q) ∧ r
which just feels really wrong, because then "i eat cereal, therefore if i eat bacon i get fat" would be an equivalent statement according to this translation
 
i feel like trying to translate that to propositional logic is an abuse of propositional logic and the english language
 
@hyper-neutrino I mean since the two are unrelated here then sure, but then that statement itself is wrong
 
9:27 PM
agreed
 
hmm
my friend looked up the slide on english translation and it literally doesn't mention what therefore is meant to mean so
 
like that's talking about motivation
 
i think it's just teacher skill issue lol
 
lmaoooooo
 
9:28 PM
true
 
When in doubt blame the teacher :P
 
well, motivation and causality
neither of which should come into play here at all
 
well for "I will build a sand castle only if I don't go swimming or diving" the solution translated it as ~(p ∧ q) → r where p = swim, q = dive, r = build
which is clearly wrong cuz p only if q is p → q
 
yeah what the fuck are they on

cool_noice is a spammer/troll from earlier today
 
@RadvylfPrograms ohh dang, now im curious as to what happened lol
 
Go through the transcripts from earlier :p
This is the sort of enlightened commentary we were graced with by cool_noice
 
11:38 PM
lmaooo
wait
is that an answer to my piet question
PIER???
also g++ wtf is that :'D
 
GNU C++ compiler
 
ah ok
i thought that g++ was a spinoff lang of c++ for a sec lol
 
It was on your piet question IIRC
 
g++ is c++ upgraded four times :P
 
this guy is literally obsessed with sweden or smth lol

yeah
And the sweden obsession continued in other posts
 
@RadvylfPrograms ok now im really intrigued, u gotta share those =P
