There has been a general movement towards intellectual relativism, pushed by advertising agencies, the media, and politicians. All of them found it very convenient to sell their stuff to targeted audiences, by telling them that such and such is good or true for them because that's who they are.

Carr there >>12067273 is not wrong, but liberalism is not the only ideology using relativism. Trump and his supporters also are not especially interested in universal truth.
Identity politics, Apple and Starbucks, fake news, and 2+2=5 is in fact all one ideology, defined as ideas that follow the same pattern and reinforce each other though that.

>>12067265
It's amazing how lefties can write so much and say so little

I get the argument being made here but the issue is we already have a variety of tools in place to represent contextually based problems. Adding ".5" to each 2 gives solves the factory example given without delving too much in the details.

The topic seems redundant.

the point is generally correct but its so contrived and pointless. 2+2 = whatever the fuck you want it to be but 3 + 3 = whatever the fuck you want it to be + 2(or some symbolic representation for "two")

2 plus 2 equals 5 is the abstraction of information confirmation
2 apples and 2 apples added to a box results in how many apples in the box?
4 is an assumption, not really the answer. if the box has a hole in it and an apple fell out then the answer will be 3. if someone added an apple into the box when youre about to answer then it will be 5.

its abstraction and brainlets like you will never understand it. stick to simple math and stop following smart people.

That’s not the answer to the previous question, you stupid donkey. It’s the answer to a DIFFERENT question, namely what happens if you add 2 apples to 2 apples and then remove 1 apple, i.e. 2 + 2 - 1 = 3.

>>12067647
yes, but in a way I kinda like what is happening because the more absurd they become the faster we will come out of this epoch and maybe we'll even call it "the absurd epoch" or "the up side down age"...

btw theres an interesting and deeper issue in the sense that uncertainty is the way of modern physics, this seems to be a "logos of history" kind of thing or as carl jung would call it "a manifestation of universal conciousness" that we gonna have to go throu in the process of history

even the whole black lives thing is eerie in the sense that it is centered on "black" meaning "negativity" more that on a real positive movement

>>12067818
Proof?

>>12067818
None of those semirings are the natural numbers under addition and multiplication. You understand that, right? Right?

You want an example of a semiring? (N, max, +). max(2, 2) = 2. Are you going to claim that 2 apples plus 2 apples is 2 apples, i.e. 2 + 2 = 2? Are you willing to put your money where your mouth is?

Stop babbling about subjects you don’t understand.

>>12067852
Nobody saying 2+2=5 is talking either about apples or [math]\mathbb{N}[/math] though; given that [math]\mathbb{N}[/math] is the initial semiring, it's totally reasonable to refer to the image of [math]n \in \mathbb{N}[/math] as an element of an arbitrary semiring, exactly the way one does in the rest of algebra.

>>12067839
read the thread I linked.

>>12067862
The main moron pushing this is a man.

>>12067859
Kareem Carr is a biostat phd student. His argument is essentially that "2+2=4" and similar statements are abstractions, and don't have a god given meaning; there are some real-world contexts in which the most convenient associated mathematical model satisfies 2+2=5, so one ought to respond to "2+2=5" by prompting for more details rather than blanketly dismissing them.

>>12067880

>>12067896
by "the image of [math]n \in \mathbb{N}[/math] in an arbitrary semiring [math]R[/math]" I mean the image under the morphism [math]\mathbb{N} \rightarrow R [/math].

>>12067896
>>12067902
fair, I tend to block out random shitposting on 4chan and refer to the mathematicians supporting the 2+2=5 thing, who talk mostly about e.g. semirings in which this is true.

That being said, I do think that the "1+1=3 because chickens" thing is more or less valid, if not asinine; they're essentially saying that there exist models that might be useful where the notation 2+2=5 is valid, which is nearly self-evidently true.

>>12067931
>I mean the image under the morphism
And what does that have to do with my post? What are you saying?

>>12067931
>in which this is true
It isn’t. You are confusing use and mention. It’s like saying true is false by redefining false.

>>12067931
>That being said, I do think that the "1+1=3 because chickens" thing is more or less valid
How is it “valid”? It’s nonsense. It’s literally incorrect. Again, are you willing to put your money where your blathering mouth is? You aren’t, because you also know it’s bullshit.

>>12067931
>there exist models that might be useful where the notation 2+2=5 is valid
There aren’t. Refer to my tropical semiring example.

>>12067906
Turns out I am not Kareem Carr, nor am I more familiar with his work than on a summary-level.

I can reference one I've seen used, but it'll be contrived. For instance, suppose you aim to describe the population of chickens; suppose you have a pen capable of housing an arbitrary number of chickens and a single egg. Use the notation [math]n+m[/math] to denote, for two separate populations of size [math]n[/math] and [math]m[/math], the population size resulting from mixing the populations in a pen and allowing a single gestation period. Then, [math]2+2=5[/math].

>>12067952
you know, tropical geometry is sometimes considered useful or interesting

>>12067960
lmao

>>12067960
If egg is a chicken, then 2 + 2 + 1 = 5, if not, 2 + 2 = 4, there's no other way moron.

>>12067967
You didn’t understand what I said. Take a breather and read it again.

>>12067936
So 2,2,5,+,= all are frequently used in reference to elements, operations, or equality in an arbitrary semiring, and there exist semirings in which 2+2=5.

>>12067960
>I’ll use the notation 1 to denote 0. Therefore 1 = 0. Voilà!
There you have it, folks. This is how of the mind of a leftist works. No wonder they're so hopelessly confused.

>>12067983
>So 2,2,5,+,= all are frequently used in reference to elements, operations, or equality in an arbitrary semiring
Name one where 2 + 2 is not 4 and justify the use of the symbol + as opposed to any other symbol. You can't.

>>12068010
>justify the use of the symbol + as opposed to any other symbol
oh so we're allowed to have 2x2=5 but the + symbol is Illegal for use in that context lel kek lmao ahaha

>>12067996
This is literally how mathematics works. To use an example that another poster used, in the tropical semiring [math](\mathbb{R} \cup \{-\infty},\text{max}, +)[/math], the "multiplication" is given by traditional addition on [math]\mathbb{R}[/math]. In the tradition of referring to the multiplicative identity as 1, the usual element 0 may be referred to as 1 if you're dealing in a sufficiently abstract context (i.e. if you're using other semirings and not caring too much about the specifics of the tropical semiring). You probably wouldn't say 1=0 in this context, since you'd probably define 0 to be what's usually referred to as [math]-\infty[/math].

>>12067960
So 0 + 0 = 1 according to your idiotic notation
Nice "addition" fuckface

>>12068026
>oh so we're allowed to have 2x2=5
Where did I say that, you mouthbreathing retard?

>>12068029
That was my example you stupid idiot, and the point was that max(2,2)=2 does NOT imply we should use the notation 2+2=2.

>>12068029
And it was in the natural numbers, not the reals. Lrn2read.

>>12068010
This example in the thread I linked was on a bit of a weird set of axioms (not including the axiom x*0=0); i don't have an example on hand where there are annihilating 0s, but many such examples have been computationally verified to exist.

It's customary to use + for the additive monoid associated with a semiring.

I'm making a prediction right now

>Liberal media discovers modular arithmetic

>2+2=1 too!!!

fucking retards

>>12068047
>>12068053
Right, I switched to the tropical semiring, rather than the sub-semiring on [math]\mathbb{N}[/math] so that I could reference tropical geometry. Again, the notation 2+2=2 is customary when viewing the tropical semiring as a semiring.

Idk read the wikipedia page or something https://en.wikipedia.org/wiki/Semiring

Nice backpedaling you dishonest turd

>>12068121
When I say "nobody is talking about apples" I mean specifically that nobody is saying that if you put two piles of two apples together, you get 5 apples. The "quantities of apples under combination of piles" thing is modeled by [math]\mathbb{N}[/math].

Why are you so angry? Are you a mathematician? This is not controversial among math people that aren't just looking to be mad at something.

>>12068088
>Again, the notation 2+2=2 is customary
It isn’t, you liar and/or dunce. The customary notation used is [math]\oplus[/math], PRECISELY to distinguish it from ordinary addition, which is denoted by +.

Again, stop blabbering about things you don’t understand.

>>12068142
>nobody is saying that if you put two piles of two apples together, you get 5 apples
they literally are though. have you even looked at these threads?

>>12068151
Are you dense? Read the rest of the sentence.

When you say "2+2" in an arbitrary semiring, you say something about the tropical semiring as well.

Doesn’t rebut anything I said, you stupid monkey. Of course the tropical semiring is a semiring.

>>12068170
Granted I mostly interact with algebraists, but those that I've talked to tend to agree that there exist semirings in which 2+2=5, and hence the statement "2+2=5 is false" is not true without making extra assumptions on the semiring you're working in.

>>12068181
yes.

Because the tropical semiring is a semiring, there exists a semiring in which 2+2=2.

Hence there are valid mathematical contexts in which 2+2=2.

>>12068189
If I say true is false, will you take that claim at face value? I really want to know if that's what you've been blathering about the whole time. That would be hilarious.

Guys. GUYS. Listen up. Important announcement. I've solved the Riemann hypothesis by redefining it as the Pythagorean theorem.

>>12068203
The statement "true is false" needs to be qualified. I'm no logician, but I'm assuming this is only meaningfully true in either inconsistent or fairly trivial logic, so I'd be inclined to say that there aren't very useful contexts where that's true.

I already explained to you that notation which causes confusion is avoided.

1 is commonly used to denote the identity element in a general monoid. It is NOT commonly used to denote the identity element in the specific monoid (N, +), for obvious reasons.

Supserscript minus one is commonly used to denote inverse in a general group. It is NOT commonly used to denote inverse in the specific group (Z, +), again for obvious reasons.

https://youtube.com/watch?v=C9SiRNibD14

>>12068336
Yes, but when somebody says "[math]n^{-1}[/math] for [math]n[/math] an element of a monoid [math]M[/math]", this does not mean "every monoid which is not traditionally referred to in additive notation."

Similarly, the statement "there exists a semiring in which 2+2=2" is true even if the immediate example would not traditionally be written in that notation. To respond to this statement by saying that it's wrong, a (((cultural marxist))) conspiracy, or some other nonsense simply does not line up with the way that algebraists understand those symbols and use them to communicate with each other.

>projecting
I’ll rephrase the point, since you seem to have trouble grasping it. Notation which causes confusion, especially by CONFLICTING with existing notation, is avoided, and for good reason. It’s bad notation. It’s stupid. It’s silly. And anyone who insists on using bad notation is being silly and/or deliberately deceptive. Not smart. Not profound. Just silly.

>>12068372
>>12068372
"most logicians and philosophers", that's just an argument by anonymous authority https://en.wikipedia.org/wiki/Weasel_word
Who the heck cares what most logicians and philosophers think. From the article of the "Two Dogmas of Empricism", one can tell that mathematics only has an origin in our experience and intuitions about space and quantity in our interaction with whatever is that we call reality via our perspective and never reality on its own. (and this perspective, our language, our experience, and the intuition we have about our experience, is just a fallible source of knowledge, not some divine source or what have you that is true for all possible context, rather it's completely contingent and parasitic to our own small existence as we contemplate the infinite but in a way that remains eternally limited, and mathematics is definitely not an exception)

>>12068391
This is only confusing because you don't understand it as well as most algebraists do.

>>12068352
>To respond to this statement by saying that it's wrong
So any time you hear someone IRL say something false, you’ll always refuse to take their statement at face value? What if their “explanation” is using terms in a nonstandard way? What if their explanation of those is also using terms in a nonstandard way? How will you ever be able to understand what anyone is saying, ever? Language convention exists for a reason. So take your nonsense and shove it up your ass.

>>12068410
What is it that you claim I don’t understand? I already showed that your notation is NOT the standard one (e.g. in the case of the tropical semiring). The only one here who doesn’t seem to understand standard mathematical conventions is you.

>>12068418
The statement I'm referring to is "there exists a semiring in which 2+2=2"

>>12068424
You don't seem to understand that it's customary to refer to an arbitrary semiring as [math](R,+,\cdot)[/math], and statements about existence of a semiring satisfying an algebraic condition need not be expressed in the notation [math](\mathbb{N},\text{max},+)[/math] to have your semiring come as a valid example.

>>12068347
why are leftists so fucking stupid and insane?

>statements about existence of a semiring satisfying an algebraic condition need not be expressed in the notation [correct, unambiguous notation]...
Are you fucking stupid? Do you legitimately have brain damage? Did I not explicitly say my point is precisely about the choice of notation used to express the statement?

>>12068463
read the sentence slowly

when I say "a semiring exists satisfying ..." I don't have to use the notation of the particular semiring for what I'm saying to be the true or for it to be good notation.

>>12068475
>for it to be good notation
Yes it does.

>>12068475
so 1 + 0 = 0 is good notation, in your estimation? fucking retard

>>12068475
So for instance would you say "there exists a semiring [math](R,+,\cdot)[/math] such that the monoid (R,+) is idempotent" is bad notation if you're secretly thinking of the tropical semiring when you write that?

>>12068495
rip should have been linking this >>12068486

>>12068495
>>12068503
No, because unlike the statement 2 + 2 = 5, it
(a) does not refer to a specific semiring like the tropical semiring, and
(b) does not refer to specific elements of said semiring using numerals, for which + has an established meaning
What’s so hard to get about this? Why do you insist on idiotic notation?

>>12067265

ALL OF THIS SHIT IS ORWELL'S FAULT!

He fucked us. He wrote a book decrying this over-the-top completely unimaginable totalitarianism, with insane technology. We've developed the technology far beyond what he described, making universal surveillance possible. And now this. The centerpiece of his book was that 2+2=4. All else follows from that: and that's what under attack.

Orwell invoked historical irony just like Malthus. History worked on Malthusian principles right up until he wrote his book. Orwell personally killed objective reality: the Frankfurt school and relativism generally is HIS FAULT!

>>12068511

First of all, they don’t, you stupid moron. Take the formal languages on the alphabet {a,b} generated by union and concatenation.

Second, your point is irrelevant. The point is that if numerals are being used then + denotes addition, by convention. This has nothing to do with whether such numerals are used in the first place.

This whole fiasco reminds me of that small movie. What a clown world we have become. It sickens me.

>>12068518
how does that address the point that + denotes addition when seated between numerals?

>>12068545
In this semiring, the multiplicative unit is given by [math]\{\varepsilon\}[/math], where [math]\varepsilon[/math] is the empty string. Since this semiring is idempotent, one might say that [math] n = 1[/math] for all [math] n \in \left\{1,2,3,\dots\right\} \subset R[/math] (for R the semiring); again, this is not all that unusual if you're in an algebraic context where you're relating [math]R[/math] to other semirings.

>The point is that if numerals are being used then + denotes addition, by convention.
Yes, + denotes addition according to the relevant semiring structure. It is not the case that numerals are used uniquely to represent the natural numbers, and + is not used between numerals solely to represent the usual addition on the natural numbers.

>>12068576
For an example of where this isn't true, see [math]\mathbb{Z}/n\mathbb{Z}[/math].

>>12068585
(assuming "addition" refers to addition of natural numbers).

>>12068580
so your choice of notation is to say that 2 = 5?

>>12068604
where it's understood that [math]2,5 \in R[/math] yes, this is standard in algebra.

>>12068585
>>12068580
>It is not the case that numerals are used uniquely to represent the natural numbers
Natural numbers are precisely what the Twattertards are referring to, hence we're discussing + *in the context of natural numbers*.

they're not though? Not the mathematicians I've seen talking on the subject

>>12068611
That’s not the way it’s expressed in the context that semiring. Mathematicians don’t use 2 + 2 = 5 to refer to {e} U {e} = {e} U {e} U {e} U {e} U {e}. This is doubly true with regard to doing so without explanation.

>>12068621
>they're not though?
You’re one dishonest sack of shit, I’ll give you that. Did you “miss” the examples of counting apples and chickens?

>>12067265

>>12068630
The "counting apples and chickens" are usually not mathematicians, and are also often talking about models which aren't really the natural numbers in an intuitive sense; there's some vague notion of uncertainty, or some more complicated construct; it's often something like "like 2 apples, but you're not totally sure" or some vague thing like that

lol

>>12068644
>are also often talking about models which aren't really the natural numbers in an intuitive sense
Wrong. They’re talking about counting objects, i.e. natural numbers. Not surprising that you’re trying to defend their idiocy, though.

>>12068644
>there's some vague notion of uncertainty, or some more complicated construct; it's often something like "like 2 apples, but you're not totally sure" or some vague thing like that
There’s no “vague notion of uncertainty” or whatever mumbo-jumbo you’re trying to pull out of your ass in the mathematical expression 2 + 2.

>>12068625
**Proposition.** If [math](R,+)[/math] is an idempotent monoid, then [math]n = 1[/math] for [math] n \in \{1,2,\dots\} [/math].

Since there exists an idempotent semiring [math](R,+,\cdot)[/math], there exists a semiring [math] R [/math] wherein [math] 2 + 2 = 5 [/math].

The point of me repeating this is to demonstrate the value of abstraction.

>>12068654
An expression has precisely the meaning it's given, and I don't know how you're getting from my post that I endorse those particular models. I literally called them vague twice to signal that I'm not a huge fan of the "uncertainty" thing in particular. My point is that they're not trying to talk about the natural numbers.

Again you open your mouth and lie. They're talking about counting objects (e.g. hens, sessions, or whatever), i.e. they're talking about natural numbers.

>>12068670
You speak of "they" as if this is a single person. When I say "they are often talking about models" I don't mean literally 100% of them.

There certainly exist examples; when people say "2 apples, but I'm not really sure, so it could be like 1.8 apples or 2.2" they're certainly not referencing bare natural numbers.

Why are you so antagonistic about this? You turn "I disagree with you" into "you're lying and a moron" (even though I'm not wrong, and if I was, it doesn't seem like it would be the disingenuous or moronic kind of wrongness).

>>12068674
Again, what part of
>there's some vague notion of uncertainty, or some more complicated construct; it's often something like "like 2 apples, but you're not totally sure" or some vague thing like that
sounds like me just totally defending them? I called their ideas vague twice in the same sentence.

>>12068682
But they're not saying "1.8 apples or 2.2 apples", are they? They're saying "2 apples".

Except that both of those cases can be perfectly fitted into the framework of mathematics, like even you do when making your point by subtracting or adding an apple a propos.

The fact that some of these actions may be unknown to the data analyst does not mean there is an issue with the framework, but instead, points to some underlying mechanism that may produce a type of noise on your data.

The point that's being made by the 2+2=5 crowd is obviously that numbers aren't always the best way to be talking about reality as they like to bring up IQ and things like that. But there is no reason to pin this on the fundamental logic of mathematics, instead, critisism should be leveraged against mainly the (soft) sciences (I think we can all agree that physics and chemistry rely a lot on mathematics in a justified way).

Saying 2+2=5 therefore makes you look dumb in my opinion because you're attacking the wrong subject, when you could have just said that "numbers do not always reflect reality perfectly" which is a much more subtle and meaningful phrase.

>>12069268
If you get noise in a form of 2+2=5, its literally a logical error, you don't just sit here and say "haha yes, 2+2 is 5 now", retard. You figure out where extra 1 came from. In fact, you already fucking know that extra 1 came from somewhere, so you know that it really was 2+2+1=5, because it literally has to be, that's how trivial arithmetic works, you ape.

The fact that you're fucking retard who missed 1 in real world doesn't mean that you can remove it and claim 2 + 2 = 5, by the way, if you don't understand what's written in this image, just stop talking. Thank you.

He's correct in his own context, you should argue about different topic here, anon.
He suggest everyone could use their own mathematical abstraction instead of publicly recognized ones for generic arithmetic (but of course it applies also to any mathematical) operations if anyone wants it. It adds another layer to computations, which is basically converting every other person's abstractions into your own, instead of everyone using universal, publicly agreed abstractions. Let's play devil's advocate and search for pros for such method:
>it gives emotional comfort for computation
>it probably aligns with one's thought process
probably, it's what you actually do in your own head - your own methods of computing and abstractions. Now you just present people information as it is in your head. And cons?
>there is no guarantee it's compatible with other abstraction
>which means it requires conversion
>conversion should use universal, publicly agreed system, you can use your own conversions but there should be publicly agreed system to coordinate and confirm your collective computations
and there's unfortunate conclusion - someone still has to use our own beloved math. Whether it's a middleman paid to perform conversions for benefit of "computational parties", or just a sane person who keeps it from failing together, or a machine that has compiler for all the mathematical "languages" out there (it's actually no different from programming languages), it all operates on something universal. If it doesn't, there would be something else on the bottom which does, or unacceptable incompability of computational methods.

tldr: what matters is a man asking whether or not everyone should invent their own math abstractions, or, as I already named them above, "mathematical languages". What we see is basically a Tower of Babel for math.

>>12069390
To sum this up:
He made his own math for the sake of having his own math. If we use publicly agreed abstractions, he's wrong, however he uses his own abstractions, which means he's right in his own math. Good for him.
Where he is truly wrong is his own advice to "ask explicitly why people think 2+2=5 and not branding them as retards". Consider the one who says "2+2=5" as A, and the one who asks explicitly "why?" as B. As A makes a claim and B gives a question, now A has to perform a CONVERSION, to either align with universal generic math, or to align with B's thought process. But does A have a conversion methods for B's thought process? Never seen telepathy before, if you ask me, although massive collaborative experience can help align some thoughts. Not a very trustworthy mechanism, by the way.
No, to totally avoid incompatibility, A have to perform a conversion to universal math, and then inform B. There is so much redundancy, it's actually hilarious, considering what we do in math is mostly simplification and generalization.

>>12069364

In what world is it even consistent?

If its not, its not even close to being related to math at all.

We have polar coordinates, and then we have cartesian coordinates, they can coexist because actual mathematicians clearly defined what they are.

2+2 = 5 isn't a definition, because I don't know what 5 - 2 is in this retarded "custom math".

It's not even consistent with itself.

>>12069410
Seriously? Is that all there is to this? I thought maybe he was trying to make some esoteric point worth considering, but you have saved me wasting the time of looking it up.

This is worse than just fucking retarded. Christ, even the flat earthers have more intellectual integrity.

>>12069410
I disagree that this sort of redundancy is bad. It's often helpful in mathematics to describe the same object in multiple ways, rather than framing everything in terms of a single "universal" example, since different terminology is sometimes helpful for elucidating different results.

For instance, to a geometer the hyperbolic plane may be viewed as the interior of a half-plane, that of a ball, that of a codimension 1 hyperboloid, etc. All of these are isometric, yet we don't demand a standard model and require that everybody frames all discussion in the language of that model.

For another example, note that [math]\operatorname{Spec}[/math] is a equivalence between (the opposite category of) the commutative rings and the category of affine schemes. Yet it's often valid and informative to refer to an affine scheme as an affine scheme, rather than talking exclusively of the relatively more standard idea of the associated commutative ring.

It's necessary at time of creation of any notation that one defines what they mean well, and it's best that they relate their notation to other equivalent notations if possible. This doesn't make the redundancy of multiple competing notations a bad thing.

>>12069403

Isn't it than more appropriate to say "2 + 2 + (literal "X" factor) = 5"?

To me it seems like the point he's trying to make is that whether or not a statement is true in your system of mathematical logic depends on what axioms you have chosen to define that system. Maybe not as profound a point as he seems to think it is, but not that controversial either.

the universal truth is in fact, more has been done for the average American citizen under Trump than any president in the last 20 years and that more could be done if his political opponents would stop feigning ignorance and funding riots.

there's a sort of undeniable optimism these past few years that the other side seems hell bent on obfuscating through stupidity, fear and irrationality.

>>12068259
its bong hit philosophy.
"why does 2+2=4"
"why cant it equal 7"
"intangible, abstraction!"
the correct response is to just tell them numbers are a form of communication.
my 2 + 2 can equal 4
and your 2 + 2 can equal 5
it makes no difference as long as we have the same amount at the end. like metric and imperial.
it makes it harder to communicate when everybody is speaking different languages as you not only need to know the math but how to convert it to something people understand.

>>12067265
Did you actually read the article?
It's nothing remotely controversial; they're just making the unremarkable point that sometimes numerical models don't accurately reflect the real world - basically a truism. It's not "cultural marxism" or "degeneracy", post-modernism or whatever trash buzzwords /pol/ has been filling your mind with recently.

I've gotta say, if something this innocuous and inoffensive makes you seethe so hard you came to /sci/ to rant about it you'd probably better take a little break from the internet.

>>12067265
You know, whatever they try to do through handwaving and more info, there truly is only one canonical "+". Sure you could try chicken addition and the like, but your concept truly is no longer an abstraction or generalization and not to mention that you lose out on so many arithmetic properties such as associativity, commutativity, distributive with a multiplication, and inductive reasoning, Not to mention the definition of addition given may not be well defined. Yes, you could give multiple ways to use "+" in ways that seem similar to true "+", but only the canonical form of the operation is as good as it is and why it truly deserves the term "god-given".

If 2+2 can equal anything I want it to be then can 2+2=NIGGER?

>Kareem Carr
Affirmative action strikes again. This is a stupid argument, because in almost every real world context 2+2=4. Unless additional information is given (ex, "2" is defined here as a symbol that isn't actually the numeral two but something else) 2+2 absolutely equals 4.
This whole argument is the type of academic word salad that makes me suggest that Kareem is not only BLACK but possibly has a bit of the Hebrew strirring within.

This is the inevitable result of universal suffrage.

>>12072473
(cont.) It would fall upon anyone stating "2+2=5" to provide additional information justifying the statment. If no such information is forthcoming, a reasonable response would be "2+2=4 and you are a retard".

Can someone explain to a brainlet how he gets the numbers 54, 26, 51, 231, 13, 11, 35 11, 52 involved in the addition of 1+1? I just mean what is the relevance of these numbers?

>>12067852
You must understand that the main purpose of this tweet was to shill the program that counted the semi-rings, created by the tweet author.

Quite typical of Andrej to try and exploit the public opinion like this.

>>12072498
Those are references to other theorems in the book that are used in this proof.

>>12067265
I really don't see why people are treating this like it is some sort of deep insight. Of course mathematics is at best a model of "the real world".

But that doesn't mean the alternative models (where 2+2=5) are equally good. The justification given for this alternate model with these stories of particular functions with 2, 2 as input and 5 as output do not seem very convincing. It seems that 2+2=5 is added as an extra axiom on top of the existing natural numbers, but a consequence of that all natural numbers are equal (0 = 5 - 5 = (3+2) - (2+2) = 3 - 2 = 1, for example). This is a very poor model: why have equality at all when it doesn't provide any information whatsoever?

Or if the desired outcome is that under some conditions 2+2=4 and 2+2=/=5 while under others 2+2=/=4 and 2+2=5, that begs the question how these conditions are to be modeled, and what we gain with this additional theory.

The quality of models is completely ignored (there is even no attempt to claim that this is irrelevant), so I suppose >>12067394 is right, that this is just some relativist propaganda.

>>12072566
thanks

>>12072608
We can already model 2+2=5 easily, here's an insight
>whoever wrote it is retarded.

What are the odds that none of these Pajeets even read this book before starting to larp?

https://en.wikipedia.org/wiki/Principia_Mathematica

If you did, you already know where 2 + 2 = 4 comes from and why its objective and unfalsifiable in our model of mathematics, and there's no other relevant model that is consistent with itself.

>>12072657
>talks about reading PM
>complains about others larping
lol

In case you've actually read a significant portion of it, I don't know what to say. Why would you read this thing unless you are a foundations/history autist? Aren't there books which have distilled the useful ideas from this tome into more readable form by now?

>>12072688
>more readable
What's unreadable about trivial fundamentals of mathematics?

And if you want to challenge things like 1 + 1 = 2 but don't want to read literally why it is like that, you're just a fucking pajeet larper.

Cope and seethe brainlet.

>>12072709
>What's unreadable about trivial fundamentals of mathematics?
Ah, so you _are_ larping. Very well then, carry on.

>And if you want to challenge things like 1 + 1 = 2 but don't want to read literally why it is like that, you're just a fucking pajeet larper.
The only thing I'm challenging is your claim to have read PM, no more, no less.

>>12072726
I did, and there's nothing unreadable about it.

Looks like you're just too retarded to figure out the basics.

>>12072608
Did you read the article?
This is a Harvard PhD working on his biomathematics disertation. He blatantly stated if you have 2 factories, each with 2 machines and each with half the parts to make another machine, than by adding them together you get 5 machines. Therefore 2+2=5.
Do you not immediately see the retarded levels this fuck twat is at? He can't understand this isn't even an addition problem, it's a multiplication problem. If there were 3 factories, we'd have 7.5 machines, and his (consistent) argument would be 2.5+3=7.5.
I am already at a fucking lose, but he keeps going. He accertains if you place a goose and a fox in a room and come back the next day, you'll only have a fox. Therefore 1+1=1.
Why does he not include the -1 that happened?
1+1-1=1. That's how numbers work. But this fucking retarded nigger is single handedly reducing my respect for the notion of diversity hires and affirmative action. Do you realize if this is what Harvard is promoting that we are all fucking worthy of a Harvard PhD? I have friends who didn't pass highschool algebra and can spot this dipshits inconsistencies.

>>12072834
Damn, those answers/arguments remind me of the sort of concrete responses early intelligence researchers in the 19th and 20th centuries got from rural peasants to abstract/categorical questions. e.g., What does a fox and rabbit have in common? The fox hunts the rabbit vs. they're both mammals.

>>12072834
t.

>>12072834
Did you read my post? I already mentioned that the machine story was unconvincing and leads to all sorts of trouble if you attempt to generalize the operation to other numbers.

I do agree that it is disappointing that Harvard seems to prioritize stories that uncritically spout convenient ideology over careful and critical analysis of their theories. Then again, this is hardly the first time institutions like that push thinly veiled ideological propaganda with nothing but their supposed credentials backing it up. Perhaps the difference lately is that the veil is getting thinner every time. I guess that no one gives a rats ass about looking at the truth or not misleading people nowadays. All I can do is hope that the worst of this bullshit stays contained in the USA.

>>12067762
You don't even know what principia means you fucking retard. You know nothing about formal systems and higher order logics or else you'd understand the entire argument being made here in that you CAN construct a system where 2+2=5. Math is not objective truth, there is simply a system constructed from which we operate under. Please do a world a favor and take an abstract algebra course, you fucking retard undergrad.
