I wonder what's the worst abuse of notation I use
The one I like is the Physicist Way of doing the exponential differential equation
df/dx = f -> df/f = dx -> int df/f = int dx -> ln(f) = x + C -> f = e^C e^x
 
It's not really an abuse of notation as long as you communicate what you mean
that's kinda the whole point of notation
 
Well technically you can't treat differentials as a division like that tho
Bad things happen!
 
Only mathematicians say that
 
I meant to reply to the ^2 thing @Slereah
 
Well that is somewhat true, but only for like
Pathological functions
Dimensional regularization is also pretty great to horrify mathematicians
 
2:11 PM
Yeah, some authors have wacky notations with regards to tensors (e.g., coloring indices brown to convey spacetime coordinate indices)
 
that's retarded
 
...
Got a link?
I want to see this
 
it exists
I can guarantee this
 
As far as horrible notations go, the worst I had to deal with was a whole book in Penrose notation
that book
 
lol holy crap
 
2:13 PM
 
@Slereah It's Hamilton's GR, BH & Cosmo lecture notes/text...I'll try finding it
 
Well I'm glad to know he's still alive
 
Einstein knocked over his water bowl
 
Quite amazing for a 19th century physicist
 
grrr
@Slereah *mathematician
 
2:16 PM
Are you doctor Emmet Brown
Was Hamilton a math guy?
Or was he both
He did quaternions too, didn't he?
I seem to recall it
I wonder if you can do GR with quaternions
Early SR had quaternions in it
 
Oh my god
Why brown
Brown isn't a good color if you want it to pop up
 
Well given that Sanskrit is almost entirely dead
It might not be ideal
 
English seems to work just fine
 
2:22 PM
@Slereah Uh, Sanskrit is one of the most thriving classical languages in the world, although only used by the intellectual class in India.
It's one point I disagree about in the article
 
That's why I said "almost"
 
@0celo7 It's tilde! I hate twiddle!! And all Germans use it
 
I would not have called latin "alive" 300 years ago either
I know there's people trying to revive it, but really outside of hebrew, trying to revive dead languages rarely works
Even hebrew isn't that common in Israel
People still use a lot the languages that they had when they came there
 
But there are sufficient speakers of the language to keep it completely alive.
 
@Danu It's twiddle.
 
2:24 PM
I dunno
I mean latin has plenty of speakers, I don't know I'd call it alive
Also there's a bunch of people trying to revive Nahuatl, it's still p. dead
 
So long as the papacy exists, Latin will not die. It is still the official language of the Church
 
yeah but it doesn't really evolve
It is a language forever frozen in time
Also since the 70's they have relaxed a lot the latin requirements
Ever since Vatican II
 
how the heck do I save in Borderlands 2?
 
@Slereah My brother studies Latin :D
 
Coptic.
You know what almost dead language is amazing, though?
Because coptic is the last surviving descendant of Ancient Egyptian
 
2:27 PM
The difference is there are places where people still speak Sanskrit as common tongue
 
@Danu by choice :P
 
It's only used as a liturgical language of the coptic church, but still
 
@Slereah Vatican 2 allowed vernacular Masses, but didn't forbid Latin Masses
 
Gaurav : I know
Same with Nahuatl
Kyle : Yeah, but that is another nail in its coffin
 
Mattur (or Mathur) is a village near the city of Shivamogga in Karnataka state, India, known for the usage of Sanskrit for day-to-day communication, although the general language of the state is Kannada. Mattur has a temple of Rama, a Shivalaya, Someshwara temple and Lakshmikeshava temple. Mattur's twin village, Hosahalli, shares almost all the qualities of Mattur. Hosahalli is situated across the bank of the Tunga River. These two villages are almost always referred to together. Mattur and Hosahalli are known for their efforts to support Gamaka art, which is a unique form of singing and storytelling...
 
2:29 PM
@Slereah I don't see how, given Benedict XVI's expansion of the Latin Masses
 
A bunch of old men speaking latin is not the best indication of a language being alive and well
One of the key feature of dying languages is when the grammar ceases to evolve
 
Define "old" here
 
and "evolve"
 
Because I know a few <50 y/o men who can speak it
 
@skillpatrol Yes, he's finishing his Master's degree now.
 
2:31 PM
Yeah but knowing how to speak it isn't really the same
You can learn ancient greek or sumerian
That does not make them not dead
 
@Slereah I don't see why this is necessary
 
age breakdown: 0-14 years: <1% //; - 15-59 years: ca 40% //; - 60+ years: ca 60%
:D
60% of people over 60
 
is English "evolving"?
 
It is.
 
2:33 PM
@skillpatrol Some might argue devolving ;)
 
@Slereah Well, I'm not a Sanskrit scholar, but Sanskrit's direct descendant Prakrit means normal language, while Sankskrit means refined tongue
 
Does New Latin count as an evolution?
 
Which means it de-evolved
 
what language has evolved the most?
 
@KyleKanos It's not grammar
 
2:34 PM
that seems to be vocabulary, though, not grammar
 
@Danu You're not my gramma
 
Languages don't really "devolve"
That is just what grumpy old men say :p
Language gain new features and lose old ones
 
Languages always improve :)
It's like entropy
 
It is just how things go
Really the point where languages die is when they just lose features and do not gain new ones
When there are less and less native speakers and as such languages features are lost in common speech
 
2:37 PM
Could just be that Latin is perfect as it is and doesn't need to change
 
Man have you even read latin
I hate cases so much
 
Yes
Took 4 years of it in HS
 
I think you should read that article to make sense of what I actually mean de-evolve
 
You know
While programming in sanskrit is probably some cranky thing
There is a neat fact
The first Turing complete system was accidentally created in Sanskrit
In the Panini grammar of Sanskrit
He uses a system to describe grammars that can be used for such purposes
Similar to a Thue grammar I think?
 
2:40 PM
@Slereah Don't know
 
Ancient Indian mathematics had this weird system for variables
Where variables were like
color coded?
From what I remember
 
the romans found algebra easy
 
Personally, I think programming languages need to accept the full Unicode and not the standard 128 ASCII beginning
 
Ah yes, there it is
 
We can then use $\pi$ to be 3.141592653... and future code-users will see exactly what we mean
 
2:44 PM
The variables were, among other thing, ca (calaca, black), nì (nìlaca, blue), pì (pìtaca, yellow) and so on
Most modern day languages accept unicode
C# has no problem with unicode
 
Yeah, but C# is dumb
 
C# is okay
 
And some languages can print Unicode characters, but you can't use them as variables
 
C# can!
 
1 min ago, by Kyle Kanos
Yeah, but C# is dumb
:D
 
2:46 PM
@Slereah Don't know much about Ancient Indian Math, so can't comment. But the section Sanskrit's efficiency in that article really gets to the point why you can't apply the logic more recent = more evolved to Sanskrit.
 
People trying to argue that some languages are "more logical" never really impressed me, really
 
english is obviously the best language
 
It's usually an exercize in outlining simple features while ignoring the awkward ones
You know the worst people for that?
Esperantists.
Oh my god.
Never talk to an esperanto zealot
 
Lojban is good
 
Ithkuil is obviously the best language
Ithkuil is a constructed language created by John Quijada, designed to express deeper levels of human cognition briefly yet overtly and clearly, particularly with regard to human categorization. Ithkuil is notable for its grammatical complexity and extensive phoneme inventory. The name "Ithkuil" is an anglicized form of Iţkuîl, which in the original form roughly means "hypothetical representation of a language". Ithkuil is presented as a cross between an a priori philosophical and a logical language. It strives to minimize the ambiguities and semantic vagueness found in natural human languages...
:D
Ithkuil is a crazy language for crazy people
It is so complicated that nobody speaks it
 
2:49 PM
Actually, I think Khuzdul takes the championship as best language:
Khuzdul is a constructed language devised by J. R. R. Tolkien. It is one of the many fictional languages set in Middle-earth. It was the secret language of the Dwarves. == External history == Tolkien noted some similarities between Dwarves and Jews: both were "at once natives and aliens in their habitations, speaking the languages of the country, but with an accent due to their own private tongue…". Tolkien also commented of the Dwarves that "their words are Semitic obviously, constructed to be Semitic." Tolkien based Dwarvish language on the Semitic languages. Like these, Khuzdul has tri...
 
I think actions speak louder than words.
 
(Hint: It doesn't actually exist, there are very few words of Khuzdul in any of Tolkien's works)
 
Dwarves do not talk, Kyle
They sit in sullen silence
 
@KyleKanos Your statement is almost axiomatic.
 
But Tengwar, on the other hand, is actually usable
 
2:52 PM
was tolkien a sperg?
 
Sperg?
 
@ACuriousMind welcome, hangover cured yet :P
@KyleKanos oh, aspergers
 
No, he was a Linguist
 
a language nerd, even
 
@0celo7 I am able to function. That's the most I can say.
 
2:53 PM
LotR was basically just a framework to create languages
 
@Slereah Not really at all
 
@ACuriousMind lol, I got BL2 and started playing...no clue what's happening
 
@0celo7 You don't need to, just have fun
 
I didn't watch the opening cutscene because cat
 
BL2 is great :D
 
2:54 PM
@ACuriousMind So tell me
How well defined is QFT if you define fields as distribution-valued operators
 
here we go again...
 
Since non-linear distributions tend to be poorly defined
 
@ACuriousMind So why is KoTR a "different beast" and why don't you like Metro?
 
@Slereah Well...very well defined if one could show that the actual QFTs fulfill the axioms of the definition, but we can't, for almost all theories :(
 
Can't it be done with like
Colombeaux algebras
Since those are for non-linear distributions
Or something
 
2:57 PM
The other approach is going path integral and not talking about operators at all, this succeeds in 2D and 3D, but has not been successfully done in 4D
 
There's plenty of other methods
Algebraic QFT and whatnot
Aukkras êqutta ogvëuļa tnou’elkwa pal-lši augwaikštülnàmbu.

‘An imaginary representation of a nude woman in the midst of descending a staircase in a step-by-step series of tightly-integrated ambulatory bodily movements which combine into a three-dimensional wake behind her, forming a timeless, emergent whole to be considered intellectually, emotionally and aesthetically.’
 
@0celo7 I don't like Metro because...it's a linear shooter that's not very funny, and I only like linear shooters when they're funny. But if you like linear shooters, then I guess it's great.
 
I do love Ithkuil
Ithkuil was made by a crazy russian philosopher
