what is the scientific explanation of me liking to smell my own farts?

Where do they come from? Are they born or made? Does anyone know for sure?

I scored 25 on my ACT exam years ago, which when converted to an SAT score, is apparently equivalent to an IQ of 124-127. What fields can I succeed in?

will actual AIs that can actually talk ever be possible in the real world or are they /x/

Scientifically, what is the best non-human animal? As in, has the most going for it to survive and thrive?

math is fucking sucks how do i create a symbolic system that can abstract values like math but more "user friendly" so to speak.

Here's something I've been thinking about recently.

{2,4,9} is an example of a set where:
>Each element is a digit 0-9
>the sum of any two or more digits modulo 10 is not in the set

What I'm wondering is, what is the maximum cardinality of such a set, and what are those sets with that cardinality? How can this be proven?

I got thinking about this after remembering a pic that some friends were sharing on Facebook when I was a teen.
It said something like "what's your fine?" and had a list of various naughty acts, each with a "fine" next to them.

It would be things like
>Kissed someone: $10
>Stolen something: $20
>Given a blowjob: $5
>Had sex: $12

Most of the fines would be a multiple of $10, with some exceptions. In the above scenario, if someone's answer ended in a 2, 5 or 7, I would know if they'd given a blowjob, had sex, or both, and 13-year-old me would get a kick out of it.
