Is this an old image or do people actually want to do a men’s health month in the same month as Pride?

Incompleteness means that maybe it’s actually impossible to prove or disprove the Riemann hypothesis, or whether P=NP. I think that’s a big deal. Maybe the fact that there are meaningful results shown to be unprovable (like axiom of choice) is more satisfying?

For me, “imagine a circle” is kind of a meaningless instruction until you follow it up with something

Yeah… electing Trump a second time kind of ruined that

Pete Martell is shook.

Also I hope it’s fake because that’s the tiniest aquarium and there’s no plants.

Maggie Simpson

You almost gave me a heart attack. It’s Marge. (that said, I trust internet perverts enough to go for adult Maggie)

Edit: oh… it’s the blurred out one

Maybe I should block more. People say you only need to block like five users to drastically improve your Lemmy experience.

Maybe it’s an artistic statement

The trick is to spend uncomfortably long trying to remember what you decided you should say

Drivers seem to love complaining about drivers

Feels inspired by one of my favourite Tumblr posts

Edit: played through some more paths and those were definitely inspired by the post :)

AMA confuses me, because every post title I come across just sounds like someone playing pretend

What progress do you get by blaming humanity instead?

It’s not bad grammar, it’s more like an internet dialect. Reminds me of fantasy books that capitalise special nouns

There isn’t even the “this is a US website” excuse anymore, like on Reddit

fossil fuels, fossil-powered transport, and the aviation sector in all public spaces

I think this includes ads for non-electric cars, which is huge. Flights too.

🍔 is the set of integers modulo 2 (more literally, if two integers differ by an even integer you consider them the same). I can write out more in a bit.

Edit: this previous post has some good comments, and you can find some of the notation and the answer on the wikipedia page for cohomology ring (they use F₂ for integers mod 2 and RPⁿ instead of Pⁿ(R)). I don’t know enough algebraic topology to actually know why that’s the answer but I can at least answer these:

The first definition of 🍕 with the contravariant thing also doesn’t parse for me, what does that “-” mean in the function arguments?

I assume it’s shorthand for saying that if you define f(x) = 🍕(x, B) then f : C --> Set is contravariant.

In the definition of 🌭, what is the n (or the P)? ChatGPT started yapping about real projective space, but I’m not sure if that’s correct.

It’s not the notation I’m used to (I’d also think of power sets first), but I think it’s n-dimensional real projective space.

and Paris made a lot of progress in getting rid of cars since then

I don’t think this is a political compass

That’s just the rule of Tumblr screenshots, you always have to include one reply too many
