What is the bare minimum background I need to jump in? What are the Category theory for idiots beginner guides? I want a good intro text for noobs and learn all the required math background under it before I start.

Watch the Oregon programming language summer school lectures from 2012. Awodey himself teaching you category theory.

Found it thanks. Is this actually a good lecture series? I'm watching it.
Is the Universe infinite for finite?
Now give me a straight answer.
I don't wanna hear "we don't know", "define finite", "it is what it is" bullshit.
Just give me the real answer.
>>8064600
in the way the current accepted idea is, it certainly points to the universe being fifnite at a given moment of time. However due to accelerating expansion into the darkness brings into question the limits of the universe. Howerver of course if you were to freeze time, and travel faster than light the universe would be finite, but due to the bounds of reality, it could be certainly considered infite. But as a real straight answer, yes it is in a givn moment. :)

So if the universe "doesn't have an edge" as they put it, then is there infinite galaxies?
If it has an edge, is there a "furthest galaxy"?
Could such a city ever exist?
No. We know of no means to levitate buildings like that.

Genuine question - what's the point of Mensa?
After attending events/talks and reading their material, the people there just seem to enjoy wasting time together, rather than doing any actual academic work. But growing up as a kid, people had always spoken so greatly of Mensa. What's happened? Was Mensa initially good?
no it was always a sub-masonic self-praising shitfest

What do you think the file size of the universe would be, assuming it's a simulation?
No Man's Sky is estimated to be 15gb-20gb, and it has 18 quintillion planets. But that doesn't include things like human memory, languages and the music of the world, or the incredibly realistic textures that make up our reality. There's the fps game .kkrieger, which is 96kb total. It is entirely procedurally generated, but still looks passable (see attached image)
I've looked at every test that mankind has done to determine if the universe is a simulation,...

The number of distinct quanta would be a decent starting point

Yeah, you'd need every subatomic particle, its position, and movement vector inme privileged reference frame that ignores relativity and has an instantaneous, universe-wide concept of "now".

I have a theory that most people are bisexual, and while this is very likely a horny crackpot theory, I would like to posit it to /sci/ for condemnation or confirmation
I think this because humans are very much social animals and sex is a good way a resolving conflicts between two competitors (like in bonobo society) so I think humans were born naturally able to do it with both sexes.
The main reason is this: For most of human history and in some tribes, homosexuality has been matter of fact or even praised as a pure form of sex, but because we are social and develop culture, we are also adaptable to new cultures and able to "turn off" certain behaviors in order to follow the norm. so therefore, because of the rise of Levant culture and identification and condemnation of homosexuality, we "turned off" that part of ourselves in order to follow the norm.
Additional stupidity
>the sensitivity of the anus and prostate implies anal sex was not only biologically allowed, but adapted to give us pleasure, although this could just be crossed wires.
>In the studies that try to detect this, most participant get erect/aroused to same sex porn, even if they claim otherwise. This implies that, even if the party involved does not personally enjoy it, homosexuality can arouse the majority of people.
>The lack of diversity in porn/people means that homosexual behavior can't be explored much out side of the norm at this time. Because of the internet, people are starting to explore more.
>the Trap mentality: AKA the "i'm not gay, I just like sucking dick" phenomenon
So what do you think /sci/?
just based on personal experience, i think everyone is bisexual, but most have a preferential bias
I think every human has an innate ability/fetish/appreciation for genitalia male or female and everyone expresses this to different extents because of social conditioning, intelligence, whatever else lends to their various propensities.
>tldr everyone likes dicks and pussies
inb4 closeted denial fag, live with my bf and get my dick sukt everyday. I've fucked 11 girls and 3 guys.
I think it's more likely that sexuality is a choice, and good people choose to become bisexual.
I chose.
People are finally waking up to you stupid science bitches. They know that your secret language is spooky and they're not going to take it anymore.
Be honest with me /sci/. Show me your runes, tell me what they mean.

Is there really any point to studying a science if you aren't some 130+ IQ genius
>>8057738
money, you need to do something at the end of the day unless you win the lotto. if you like the kind of work why not? you still assist people with 130+ iq. and you never know you may figure something out, though you probably need more than 105 for that.
>>8057747
I'm only a 115 iq brainlet, but thankfully not as low as 105
Dont worry about iq op just do something that u are good at/enjoy.
Ive got a pretty high iq but i live rent free at home and make 20 an hr. Theres more to life than lamborghinis.

>new information on Martian atmospheric loss suggests it took billions of years confirming Mars as a viable terraformation target
There is literally no reason to not terraform Mars by nuking Phobos out of orbit. The amount of dust and debris a collision like that could kick up would be more than enough to start the terraforming process and we have the technology to do this today. Phobos is already going to collide with the...

Woah woah woah now let's HOLD ON, here. This is an emotional moment for all of us, but this MOON has a substantial DOLLAR VALUE attached to it, okay? And if in fact any alien life forms do exist on Mars, there might be an important species we're dealing with, and I don't think you or I can make the decision to do something rash, that might arbitrarily exterminate them!
I will only pay for it if we actually get good video of this shit exploding.
I refuse to otherwise.
