How did humans evolve so many anti-social traits when we've always depended on being nice to each other for our survival? We've never been able to survive on our own and pass on our genes if we didn't get along with the group until very recently were people now just have to attract a partner and have sex once and then raise the child alone in their anti-social manner without ever having to get along with even just one person. Are the anti-social traits new or have people always had them?

Your feelings aside, are there any evolutionary benefits of being homosexual?
If not, why hasn't it been erased from the gene pool?
>>8918170
There's some strange predisposition for the straight siblings of gay people to have a higher rate of twins.
>>8918170
No. The devil.
Historically people had children just for the benefits of looking after their parents, it was less about attraction and what you wanted and more about just doing it to keep your family alive. Then when life became easier as more civilised society developed many gay men still had to hide their gayness so would have wives and families, it's only until relatively recently gays could live completely free and openly and it would've been possible gayness would have disappeared due to natural selection but now they can have kids too. Also you have you consider that gayness may just be recessive and pop up occasionally in family lines.

oh hey it's that meme that was a thing for one day and hten everyone immediately forgot about, cool
Let me ask a couple of simple questions.
Can it be built using today's technology?
If it can't, what technology is lacking?

No.

Literally magic materials.
any of the carbon meme materials could do it. the problem is fabrication. because even one atom not in the right place causes significant lost of strength. enough atoms wrong close enough together will cause failure.
i'm talking less than a gram of carbon atoms over the entire structure.

I've just finished reading Arthur C. Clarke's Space Odyssey science fiction series. In the series, especially the lesser-known latter two books, Clarke spends extended time with this idea. But although it's sci-fi, he does annotate his books with substantive (literal in-text citations in some cases) references to published science-fact material, which he takes as his starting point to give his fictional version.
Specifically, in the notes to 3001 (which spends the most time with the space-elevator idea, as massive permanent towers have been erected off the earth's surface), Clarke mentions the well-known allotrope of carbon, C_60, but then goes on to mention that Dr. Smalley et al produced a tubular form, which Clarke and Smalley suggest is a possible material for space elevator, as this poster >>8924977 presumably intimates.
The text of 2061 literally contains, right at the end, the citation of this little article: "Satellite elongation something something, true skyhook". I can't be fucked to reproduce it now (I have it) but it's a little published note suggesting the idea that OP is asking about and which was popularized in the above somewhat.
This is basically all formalized speculation, some of which has been dignified with publication.
Say you are going 2 km/hr slower than the speed of light in an airplane. What would happen if you got out of your seat and ran down the aisle (towards the front) at >2 km/hr?
you wouldnt be able to run that fast, the closer you get to the speed of light the more energy it takes to go faster, If you graphed it it would look something like the picture
>>8924902
but if you're traveling at a constant velocity the entire airplane relative to you seems like it's not moving at all so relative to the plane you can move as fast as you like right?
or does the energy it takes to accelerate approach infinity even though from your point of view the plane doesn't seem like it's moving at all?
>>8924907
Its your total velocity, relation to what youre in/on has nothing to do with it
How come unhealthy food tastes good? From a biological perspective, shouldn't the healthiest foods taste the best? If eating carrots and celery makes you more healthy, and thus more attractive and live longer, shouldn't evolution favor individuals who do over people who eat pizza and drink soda? Do our genes have nothing to do with what we think tastes good? If it doesn't then why do animals have diets? I always figured it was because they evolved to want those foods.
>>8924493
Back when food was scarce, our taste made sense. High calorie stuff tastes the best because when food is scarce all you can do is try to maximize your calories and hope you don't starve.
Food hasn't been abundant for long enough to really affect our evolution much
The healthiest foods can taste the best. Do you know how fucking delicious a kale and tomato salad is, with tofu and shredded carrots on the side? You would know when you've stopped eating garbage.
Unhealthy food is scientifically designed for extraordinary mouth pleasure. Healthy food appears bland when all you become addicted to unhealthy foods (sugar, carbs, etc). But once you kick the addiction, healthy food becomes delicious. My mouth is salivating right now thinking about salmon kabobs with onions, peppers, mushrooms and tomatos. Mmmmmm.
>>8924493
sugary things taste good because, you know, our brain runs on glucose
eating too much sugar/carbs hasn't been a problem on an evolutionary time scale - it's a very recent thing
how/why should evolution select against something which has only become an issue in the past few decades/centuries? not how it works.
Now that the dust has settled, can power engineers be considered real Electrical Engineers? They appear to be nothing more than glorified electricians.
Is there any reason whatsoever besides it being easy, to be a power engineer, or are they permanently BTFO by real Electrical Engineers?

But doesn't it feel degrading to go through 4 long years of school only to work at a job where you barely use any of it?
I mean all the competition of Engineering school just to design a basic three phase power grid, while all your friends are out designing phones and military hardware.
>>8924296
all my friends are also working 50-60 hours a week and are subject to a highly volatile job market.
more importantly, most engineering jobs are only ~30% actual "engineering", the rest of the time you are answering emails, doing logistics, and disseminating technical information. thats universal for engineering regardless of how complex or ambitious your project is.
i'd rather punch out 40 hours a week and side hustle with my PE and still have enough energy for my own projects on the weekends. i did the cutting edge thing. it fuckin' sucks ass if you aren't married to the job.
I will construct a bijection from the open interval [math](0,1)\subseteq{R}[/math] to [math]\mathbb{N}[/math]. It works as follows:
Let [math]x\in (0,1)\subseteq\mathbb{R}[/math]You give me the number of decimal digits [math]d[/math] needed to represent [math]x[/math], and I will give you the interval in [math]\mathbb{N}[/math] it appears on. This interval will have the exact number of natural numbers as the number of possible reals that require [math]d[/math] digits to represent (thus bijection).
[math]d=1[/math]: [math]x\in [0, 10^1)\subseteq\mathbb{N}[/math]
[math]d=2[/math]: [math]x\in [10^1, 10^3)\subseteq\mathbb{N}[/math]
[math]d=3[/math]: [math]x\in [10^3, 10^6)\subseteq\mathbb{N}[/math]
[math]d=4[/math]: [math]x\in [10^6, 10^10)\subseteq\mathbb{N}[/math]

Is it wrong to deduce your own IQ through percentile performances on standardized tests and then averaging them together? By doing that I get a 120 IQ estimate for myself which is merely "high average" but I feel more comfortable knowing my limitations
> 31 on the ACT-- I know ACT/SAT aren't full-fledged IQ tests but I understand there is some kind of correlation. A 31 is 96th percentile
>took SAT math and got a 700-- I always perform much better at reading/writing so let's assume an equivalent 700 for that, which would put it at 1400, but 1400 is best case scenario so let's knock it down to 1300. A 1300 is 91th percentile
>I took the military ASVAB and got 98th percentile, but I'll knock it down to 90th percentile to account for all the retards who join the military affecting the numbers
>the mean of these numbers is 95-- to be safe and adjust, knock it down to 90th percentile overall performance
And the 90th percentile for IQ is roughly 120 maybe give or take a couple of points, I could knock it down even further to 85th percentile which puts me at 115-120
is it retarded to do it this way?
>>8925098
You clearly have an IQ of a nigger. These tests can all be prepared for through brute forcing practice exams everyday.
>>8925139
sure but I didn't brute force them and if you're competing with people that did brute force them wouldn't that put your "actual" score at a higher number? and can't IQ tests be brute forced as well?
op you are asking anons to gauge your intelligence, you are doing it wrong
I bought a TI 83 for $30. Is that a good deal? Any cool tricks I can do with it?
>>8924541
Fine deal. Not really any tricks you can do with it that you couldn't do with sage/octave (both softwares are free). The only thing keeping calculators alive is the fact that phones/laptops have too many capabilities that make cheating too easy.
