So what does /sci/ do to combat global warming?
I personally try to influence my peers to read into it more by posting about different things on facebook from denialism, false logic tactics, and examples of current events caused by AGW.

This isn't a thread for open debate on AGW.
Anyone who isn't a contrarian, or a shill, or a redneck with a personal interest in fossil fuels knows that it's a reality and that we have to rectify our energy and production systems.
What I want to hear is if any of you do anything about it.

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 can suggest a work related to the subjects I mentioned earlier, and gather enough interest for it, we'll provide support and a channel for it.

If you decide to join, you just have to leave an email here so I can invite you to our slack team. The email can be a throwaway, you will only need it to activate the account I think.

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 came close to developing intelligence, we would have wiped it out a long time ago, it wouldn't ever coexist with us in the early dawn of man.
>>
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.

> 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.

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 of events, the version of GNU which is widely used today is often called “Linux”, and many of its users are not aware that it is basically the GNU system, developed by the GNU Project. There really is a Linux, and these people are using it, but it is just a part of the system they use.

Linux is the kernel: the program in the system that allocates the machine’s resources to the other programs that you run. The kernel is an essential part of an operating system, but useless by itself; it can only function in the context of a complete operating system. Linux is normally used in combination with the GNU operating system: the whole system is basically GNU with Linux added, or GNU/Linux. All the so-called “Linux” distributions are really distributions of GNU/Linux.

Is human overpopulation is a concerning problem? Do we have some ideas how many people the earth can sustain?
97 posts and 6 images submitted.
>>
>>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.

>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.

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.
