I really need to refresh my set theory symbols. I haven’t taken that class in… oh no… Almost 30 years
How do students who are always involved in mathematics and physics get to know about sex?

∪ is for “union”, aka “disjunction for sets”, ∈ is for “includes”, ⊂is for “subset”, don’t confuse ⊂ with ⊆, which also allows for both operands to be the same set.
Difference between ∈ and ⊂ is that former takes an element and a set as operands, latter takes two sets.

I understand at least 20% of text, upvote. This is how much obscurity tolerance is needed to enjoy memes over here.

I don’t like how the pairs $(h, h^‘)$ are implicitly the same as $(h^’, h)$. I think the post confuses the pairs with small sets. Normally, order matters in a pair.

The formatting on your comment seems have gotten a little messed up, so appologies if I’ve missed your point, but the paper seems quite specific that the pair
(h,h')is not equivalent to(h',h), especially in term of Def 1. For instance, the result off(h,h')may be positive while the result off(h',h)is negative or zero.Tlaloc_Temporal@lemmy.ca 3 weeks ago
The formatting you’re seeing is controlled by carets (^). Just replace the start and end of the superscript text with them.
I see this often when talking about exponents: x^2 is less than x^3.
The superscript needs to be surrounded to work properly: x^(x+1)^ is greater than x^(x-1)^.

Porn on the internet, just like everybody else.

If I’m reading this correctly, then an orgy isn’t an orgy if there is at least one person not fucking. This means that a single camera person not getting any turns what could be an orgy into just a set of sets of people fucking.

No, it just means that the camera person doesn’t belong to the subset of H that makes up the orgy.

i know this meme is quite old but i still don’t agree with it. sex is not about [what other people call “sexual intercourse”]. instead it’s about having a pretense to meet other people. i believe that the underlying dynamic that moves you to go to parties and meet other people is mostly sexual. i.e. you wouldn’t go out so much just to make platonic acquaintances. but once that you’re out, you also talk to other people! which brings communication into society.
