If you start at 1 start counting, you will say a natural number more often than you will say a square
But how can there be more squares than natural numbers if for every natural number there exists one square?

>But how can there be more squares than natural numbers if for every natural number there exists one square?
there aren't more squares, for the reason you just said
n <-> n^2 is a bijection so they have the same cardinality
>>9019375
That capsule also ripped off a dudes legs
>>9019378
What if you started counting and then kept track of how many squares and non-squares you found
Could not it be proven that after a certain point the amount of non-squares will always exceed the amount of squares?
>>9019387
if you're just keeping a running tally then of course after any finite amount of time you'll have counted more non-squares than squares, unless you stop counting after 1
>have two infinite sets
>say one has "more" than the other
>>9019389
or stop counting after 4 i guess
if you count n numbers there's at most sqrt(n) squares, and n-sqrt(n) non-squares, for n>2 n-sqrt(n) > sqrt(n) so there's more non-squares
>>9019396
but every single non-square has exactly 1 square associated with it

Oh look, I found a fucking dipshit.

Source?
there exists a bijection between [math]\mathbb{N}[/math] and [math]\{ n^2 \mid n \in \mathbb{N}\}[/math], given by [math]n \mapsto n^2[/math]
in layman's terms, there are precisely as many natural numbers as there are squares (at least from the point of view of modern mathematics)

Yeah, me too.

2 isn't in the codomain, so that's not an argument for non-bijectivity
>>9019375
what if something goes wrong? does that capsule have an ejector seat?
>>9021054
yes of course it does. and if the ejector seat fails you can just eject your fucking brain out of your skull with a pistol you stupid piece of shit.

>That's not a bijection (no natural number maps to 2, for example).
it is, look at the codomain
>>9021062
but would my brain deploy a parachute?
>>9019384
Lol I can see how that might happen.

2 is not in the codomain
>>9019389
You are enforcing an order by counting sequentially.
Say you counted one integer and two squares repeatedly, i.e.
1, 1,4, 2, 9,16, 3...
If you counted infinitely, by your logic there are twice as many squares. This is why this is not a proper way of addressing the problem, as it leads to contradictions
>>9021149
so are you talking about numbers or something?
