Alright /sci/, I just realized that I barely have any dank science/math/philosophy memes. Anyone wanna help out? I'll start off by dumping what I have.

About a month ago, I made a thread to recruit people to our group-studying chatroom. We focus on mathematics, philosphy and computer science. We recently finished our Logic I course, and I'm reposting to see if more people are interested in joining. This sunday, we're continuing with a Logic II course (using the book openlogic), but we decided to also undertake more reading projects. Along with Logic II, we're doing SICP and 'Goedel, Escher, Bach'. you can join the related channels and freely participate in the reading/discussion. But for anyone who...

shameless bump
A thread for questions too stupid to have their own thread.
I'll start: pic related, where the fuck does the 2/3 come from?

Context? What are the brackets?

Why are we the only intelligent species on the planet? Intelligence seems to be such an advantageous trait that it seems weird that other animals don't have an intelligence race. And we didn't even compete for intelligence (maybe?).
And not only are we the only intelligent species on earth right now we're also the only intelligent species that has EVER existed on earth.
Think about how crazy that is
>>8051743
Not crazy at all. Evolution isn't a buffet where you pick whatever trait you like best for the next generation. If an advantageous mutation occurs (read: random) it might be kept next generation and spread throughout the population. If something works, it spreads (roughly speaking). Our brains could probably be a lot more optimized but they weren't, because they were already advantageous enough to ensure both our survival and complete dominance over every other species in the food chain. Even if something...

I think it takes a lot of coincidences. I mean chimps are getting smarter. There are also Dolphins. Maybe intelligence is a relative thing. Are we really that much better off as a softer civilization than we were as a bunch of hunter-gatherers? I think we just exist, man. What we do with it is what matters.
>>8051743
> Why are we the only intelligent species on the planet?
We literally aren't, lots of other animals use tools and language. We just do it more.
Hey /sci, tomorrow is my AP calculus test, and I wanted to know if there was anything you believe I should cram.
Fuck if I know
If you don't know how to do everything already then you're fucked
>>8051091
I know how to do most things, but I was looking for tricks, shortcuts, or any advice from anyone who has taken the test.

I reallyy hope we do develop ftl travel at some point

I'd just like to interject for a moment. What you’re referring to as Linux, is in fact, GNU/Linux, or as I’ve recently taken to calling it, GNU plus Linux. Linux is not an operating system unto itself, but rather another free component of a fully functioning GNU system made useful by the GNU corelibs, shell utilities and vital system components comprising a full OS as defined by POSIX.
Many computer users run a modified version of the GNU system every day, without realizing it. Through a peculiar turn...

yeah we just need materials that don't exist in this universe
Is human overpopulation is a concerning problem? Do we have some ideas how many people the earth can sustain?
>>8049364
It's not so much overpopulation, but over consumption, and to a lesser extent poor allocation of resources, that's going to be a bigger problem in the coming years.
>Do we have some ideas how many people the earth can sustain?
Looking at the carrying capacity of the earth with respect to humans is a bit pointless since we can engineer solutions around problems.
it probably helps that a pretty good fraction of people are starving
>>8049364
food produced per year: enough for 11 billion people
starving people: 1billion+
consumption of food resources of average westerner = 32* consumption of food resources of average kenyan (and no, there is no starvation/war/massive virus outbreak in kenya)
Solution if you think overpopulation is an issue: sterilize americans, europeans and japs.
Why are physics and math the only two fields that are intellectually challenging?

All nature science based on those two

Calculus is a subset of Analysis

Game theory and everything derived from it are extremely useful in many situations
>newfag alert
I would like to teach my self maths. To eventually get into advanced topics such as but not excluded to abstract algebra, multi variable calculus, game theory or graph theory.
I learn very effectively from studying from books and text book.
>also poor fag alert
So school isn't much of an option right now. I would like to do this all on my own.
What do.
>inb4 kill self
OP here.
Would also like to note that I have a year and half of uni under my belt and the highest math I took was calc 1.
>>8050451
Abstract algebra and multivariable calculus are supposed to be first year modules... in which case, can you list which modules you have taken, and a small summary of what they contained?
>>8050468
OP again.
I was compsci major. The only math I took was calculus. We fully covered derivatives, and began integrals at the end of the course. I would have covered integrals in the next course but had to take that semester off because of reasons...
Yeah. So as you can tell, I am also a newfag to maff as well.
So /sci/ what's the science behind wormholes
>>8050184
Anything more than that silly picture is really complicated math.
>>8050184
Ancients putting equations into your subconscious mind.

Are you fucking retarded? Scientists don't even know whether they exist. It's all in experimental state. Nobody has ever seen them and has been able to determine and focus by scientific methods.

hello lads, so I am interested in this point. Would weed help stop cancer just as good as chemotherapy. Also if you had cancer would you take chemotherapy or not? Finally, does weed actually help prevent/stop cancer?
ty in advance, btw non pic related, idek what this pic is doing on my pc anyways
>>8050005
>Would weed help stop cancer just as good as chemotherapy
no, chemotherapy wrecks the shit out of cells, there's nothing in weed that does that.
>Also if you had cancer would you take chemotherapy or not?
depends, it's probably a good idea
>Finally, does weed actually help prevent/stop cancer?
I'm gonna go with most likely not, smoking it definitely no, it'll probably make you get cancer faster.

I just smoked and I dont have a tumor so yeah fuck off
Imaginary time allows you to make sense of time "before" the big bang, time within black holes, quantum wave-particle duality, and many other things.
Why have people not adopted the use of i time in physics?
because physics isn't about imaginary things weeaboo faggot
>>8049816
>"I don't understand what imaginary numbers are"
It is just to say that there are multiple "directions" of time.
>>8049811
>Imaginary time allows you to make sense of time "before" the big bang, time within black holes, quantum wave-particle duality, and many other things.
I'm pretty sure it doesn't.
Has NASA experimented with masturbating in space?
>>8049757
If they have they havent realeased any data. No doubt astronauts have done it, and its not unlikely they have reported any interesting results
Officially, I think not. But maybe some astronaut has done some extra research in his/her spare time.
>>8049761
I'd like to do some extra research if you catch my drift
masturbating in space
