Is it a legitimate concept or entirely hormonal or whatever?

I'm interested in any actual data about it.
92 posts and 7 images submitted.
>>
The last edition of the DSM added an entry to clarify that it is not a mental disorder, and there are many people who identify as asexual who have had their hormones check and found normal. It is not the same as having a low libido... it is simply not wanting to direct their sexual desire towards anyone. There are asexual people who have normal or even high libido.

I'm not asking if because in my mind it's an inevitability. My question is WHEN. When will human driven cars not be allowed on the road? I believe we will have full on self driven cars on the roads in at least 5 years and at most 10. No way it'll be longer than 10. So with these self driven cars when will human driven cars be outlawed on the roads? Human error is the cause of almost every accident so self driven cars are definitely the future.

pic related. Stop lights will no longer be needed if all cars are in constant communication with each other communicating at the speed of radio waves back and forth between any and all cars nearby. It'll be safer and more efficient if there are no human drivers on the roads.

Intersections like that may not be possible yet because you cannot predict road conditions and such. Rate of acceleration/decelleration may vary.

And not every traffic collision is the fault of a human. Icy road and a large animal comes into the path of the car and it is unable to stop. Nobody is at fault. Infact a human driver may have an advantage as it could swerve into a snowbank and have a softer landing instead of hitting a moose that weights half a ton.
>>
>>7952845
The onboard computer can sense road conditions because... you know... it's on the road. It can tell if it's icy or what not. Also I guarantee you a machine would have a faster reaction time than any human. They'll break quicker or swerve quicker.
>>
>>7952843
maybe not ever. You can still see horse driven carriages on some roads today.

humanities articles are better grammar and vocabulary.

stem articles are written by 12 year-old who can hardly speak but yet manage to think that they are pedagogical in their communication. Their topography is equally awful, since they think that it is enough to use latex to have a good article. The best part is when they leave a baseline stretch of 2.

Now the content. The stem kids think they have content because they cling to their fantasy of the relevance of the formal deductive reasonings, with a bit of induction to validate their speculations.

The humanities people at least do not pretend to discover the truth and bring it to the plebs. They share their opinions and know the limit of their endeavor.
The stem kids get butthurt very quickly from the way the people humanities communicate. But then nobody cares much about what stem kids talk about, since hardly anybody is willing to embrace their autism.

I was adopted 19 years ago. My mother and father told me it's impossible to trace back my biological parents since I was born in a third world country and there weren't documents. Are they telling the truth, will I never get to know my biological parents?

Unless your biological parents have their DNA sequence registered in some lab for some reason it might be extremely difficult, if you come from an orphanage maybe they kept records but I'm not sure you're allowed to access those.

How important is abstract algebra for physicists?
20 posts and 1 images submitted.

Very. Luckily it's considerably easier to learn than the other types of mathematics that are important to physicists.

>>7963299

What area? I've heard it's most used in theoretical physics, but I'm still not sure if it's worth learning it.
>>
>>7963306
I don't understand. The very worst case scenario is that you learn something interesting that you don't have an immediate use for. What do you mean "if it's worth learning?"

After my brain has decayed, at some distant point in the future, won't it reform due to quantum fluctuations and tunneling, along with some super computer attached to it that will simulate my life from the day I was born? Why is it not likely that this haven't happened 1 billion times before? Will we ever know? Also pic related.

I don't think anyone has or can say that this hasn't happened. In all likelihood that's exactly what happens, and we're all doomed to repeat our lives eternally.
>>
This is what I thought as well OP.
>>
If the universe is finite, and the probability of such an event is so low, there may not be enough time in the universe for such an even to take place.

>(example)
The universe will last for x years. The probability of the described system occurring in a particular year is p. Therefore the chance of it NOT occurring over x years is (1-p)^x. As p approaches zero, the probability becomes (1-0)^x, or 100%.

Of course the chance of your scenario isn't zero, but it's pretty damn close. If x isn't large enough there is no doubt that such an event will almost never happen.

Parroting everything your professor says and pandering to his viewpoints like an obsequious cuck builds your critical thinking skills, obviously ;)

Because nobody wants to hire a one trick pony with no social skills to work for them. Despite what you may think, being a well rounded individual makes you far more interesting.

Because then the dichotomy of rich and poor would expand when brainlets are forced to learn at the same rate as Newton.

Standardized educational systems aren't effective unless they take the middle ground.

Up to the parents to recognize your potential and put you into a private school if they think you're a genius.
>>
>>7956390
Private schools aren't for geniuses. Source: I went to private school. It was full of morons who wouldn't have been able to graduate had the headmaster not cut them some slack at the end of every school year.

There isn't enough time in the school year. Furthermore, other topics of study must also be introduced

Why aren't there any big research projects concerning behavior modification?
Since we can use Applied Behavior Analysis to effectively shape autistic children into behaving correctly, and if we can use advanced marketing and rhetoric to easily induce desired emotions and purchasing behaviors, why don't we start researching this highly promising field of behavior modification?

>quality of life goes up and mortality goes down

>corrupt regimes and dictatorships are eliminated because the counterpropaganda created via this research would be so powerful as to completely undermine them

The big project is called a global economy. Mass social control and modification is expressed as economics. Just look at most of the threads on this Mongolian shitposting board.

Anyone willing to point me in the right direction on a puzzle I'm working on?

Its a geocaching puzzle that involves multiple ciphers, and I'm stuck at a clue that seems to point to a SPnetwork.
This is output from a checkerboard cipher-
ggsortkaorossonontcvtnoodntvattprcrspsp
>>
The next clue suggests squares or boxes, and the letters S,P

I'm solving for xx.xxx, yy,yyy- so I backed up a step, and divided the input to the checkerboard to get-GGRTORONCXONTUPRSP and
OSKAOSSONTBTODBATCRSP
there is a clue that deals with case sensitivity, so I've used a number base converter to input the letters as base64, but this SP network is over my head
>>
the next clue seems to suggest keeping your lines straight, so I've been leaning towards the Rijndael s-box as wiki describes it involves an affine transformation that I think would satisfy the "keep your lines straight" clue
