There's nothing to do, females have the same access and the same treatment.
Just go to r9k or something.

I just wanted to remind you all today that before you start calling other posters dumb that you are ALL brainlets.

My mind is like a hive with thousands and thousands of bees. Each bee has a brain just like yours.

How many of you autists ARE NOT positivists? And why not? I bet some of you have been espousing positivism without actually being aware of it as a philosophical position or of the many arguments against it.

>Positivism is a philosophical theory stating that positive knowledge is based on natural phenomena and their properties and relations. Thus, information derived from sensory experience, interpreted through reason and logic, forms the exclusive source of all authoritative knowledge.[1] Positivism holds that valid knowledge (certitude or truth) is found only in this derived knowledge.[2]

>Verified data (positive facts) received from the senses are known as empirical evidence; thus positivism is based on empiricism.[1]

>>8335675
You should leave the situation because you'd get charged with murder if you pulled the lever.
>>
>>8335735
Probably this, but perhaps this is the most complex one, because you have to wonder what is real.
>>
>>8335815
5 people get killed if you leave the lever, but there's a 2/3 chance that those people won't even be in our universe. So it's obviously for the best to not touch the lever. People in other universes don't affect us.

Tie a rope around the Earth's equator. Now untie it, and add one meter of rope. Tie again. How loose will it be? In other words: what will be the distance between the ground and this rope going around the Earth? Most people will either answer "close to 0" or (a few) "one meter". Do the math, and the answer may surprise you.

^mind was blown

>>8335536
I think you stated the problem backwards, because the actual answer is 1/2pi meters which is pretty close to 0 compared to 1 meter. My mind was not blown.
>>
>>8335536
D=C/pi
D2-D1 = C2/pi - C1/pi = (C2-C1)/pi = (C1+1+C2)/pi) = 1/pi = ~0.24

so about 12cm?
Not sure what the point of this was, unless it's your homework.

Hey fellas. I was walking home with some friends and we argued about probability.

If an attack has a 10% of landing, and you attack 5 times, what percent chance do you have of landing once?

>>8335435
0.5%

I don't understand. Why would it be 5 out of 10 chance if each attack is independent of each other?
>>
>>8335435
1-0,9^5=0,40951; -> ~41%

>>8335370
>Why are the insides of hands lighter than the upper sides?
Because they're not exposed to the sun as much as the outside, so less melanin is needed to protect them from UV radiation

>And wtf is going on this this ad, I've never seen such hands.
This is probably shopped, for aesthetic reasons.

This easily testable nonsense, the tongue map, long since debunked, is still being taught in academia as scientific fact, simply because the guy who wrote the book 60 years ago said it was true.
