Alright, dickheads! Everyone constantly whines about how there's all this fucking space debris around the planet.

How do we fucking clean it? I propose a giant fucking electromagnet. Lets see you come up with something better.

Yes and kill every computer database worth more than your future lifes if you don't go to hell after you die.
Good job senpai.

The only way we can fix this shit is worldwide cooperation, but some countries just want to watch the world burn (see the chinks and their contamination).

and satellites designed to detect debris so the lasers can fire from ground bases and zap the garbage

you seem to be smugly waiting for your chance to post some article about ozone levels from 1970 onward, dick in hand. Let's have it then, no need to keep people waiting.

have ozone levels returned to pre-1950 levels? or not?

Could it actually be harmful to have extremely strong immune system? I for one haven't been properly sick in four years, not even the normal influenza / flu during winter time. The example case I've read about was that those people who get the H5N1 influenza die because of their extremely strong immune response to the disease (cytokine storm). Any expert on the matter who could chip in?

I never used to get ill with flu or anything but then got lung cancer at 25 so I'm not sure if that means anything.
>>
>>8729946
Are you the same brit who posted this to /pol/ a while back? Cancer is a different case though, cancer at young age is almost always due to genetic defects. Your immune system doesn't play a huge part in fighting cancer
>>
>>8729934
It is EXTREMELY harmful.
To other beings. Bahahahahaha.
Also it could be that you never go out or even vaccinate yourself. In which case when you do actually get infected by a real disease you will get super sick.

i believe there will come a time when most means of production will be automated then nearly all workforce (entirety of blue collars and white collars to some extent) and and it will be at that time that the ruling elite will mass murder the world population and reduce it to a ridiculously small fraction, then the singularity will come and scientific breakthroughs will follow a geometric series. telomerase inhibition will be perfected gradually slowing down human aging combined with a very advanced medical field. space colonization will be the next step by the descendants of the few hundreds of selected families allowed to live after the mass extiction event.

we'll all be already dead by then though.

That's okay. Musk will ship us to Mars, where the planet is already totally fucked, so we can live there in domes and underground. So, we don't need to do that on Earth.

Question to aspiring mathematicians. Since this guy was at 18 probably more knowledgeable in math than you will ever be, knowing this, how do you motivate yourselves? Go into some niche branch of math, since no one can know everything?

It's not a competition for some people. It's just fun for them. They could be better or worse than they are now and they would still do the same thing.

A constant factor of 2 is meaningless in this case. You can use your own version of pi-slash if you feel like it, but it seems like a massive waste of time.

Hurt myself, got a tetanus shot.
First my arm felt a bit sore, like when I did too much workout. I tried to sleep on it, and now I start to develop flu-like symptom. Joint pains, muscle aches, unfocused mind.

Its a weak version of the virus.
You are now in the supposed highest point in your bodies fight against the tetanus.


Unless you have a REALLY weak immune system then you should be fine and this is as bad as it gets....

Vaccines are designed with a weakened "dummy" virus/bacterium so that when the REAL bad guy comes along your body can defend against it.

Why don't food manufacturers call everything organic? Everything has carbon in it, right?

Because organic is a meme label to attract hipsters and soccer moms and make them feel good while not actually doing anything; it doesn't really mean anything at all.

Who's to blame for this? The school? My brother? Why are kids not appreciative of math? And you know what, he kind of has a point. He doesn't want to go to college for STEM, he says he wants to go be a graphics designer, and he does know how to draw. Would he really benefit from knowing all the stuff they teach him? I'm going to college for a Mathematics major of course, so I appreciate the stuff I learned in school, but still. That's just me.

Oh please. School is not really about getting any life skills. It's about getting a horizontal view of a lot of topics, so you can at least have some minimal knowledge, and to help you decide what you want to do with yourself.
I don't see anyone complaining about literature even though it's "just as useless".
The point is to give you a taste of a wide subject, not to give you actual tools.

People like to assert that trans-humanism will make humans able to compete with machines, but this is a false assumption for several reasons:
>trans-humans would be people born as humans but with added cybernetic augmentation, meaning they have inherent flaws as all humans do
>cyborgs on the other hand are built from the ground up to work as highly optimized machines
>they can look, behave and speak exactly like humans if need be, but would not be limited by anything other than volume
>extreme intelligence that would not be possible in augmented humans due to limitations of the mind (think x100 or x10000 times the computing power of a human brain + quantum computing which is not possible for humans)
>extreme strength (built from the ground up rather than meme nano-fiber enhanced meme muscles in trans-humans)
>could perfectly manipulate any human through coercion or sex (again, their human-mimicking abilities)
>will be able to replicate themselves and evolve themselves faster than anything we can counter with, all while blending in perfectly
>even of they aren't "enemies" of humanity, they would be so perfect in comparison that humans would remain permanent irrelevant monkeys
Anyone else on /sci/ scared shitless of these things?
I'm literally 80-90% certain that I'll meet my end by some cyborg woman in the not too distant future.

Ebin meme friendo. Like 99% of "humanity's flaws" arise from game theory and are observed in nature all the time. Which means ayyliums and AIs will be massive cunts just like us.
