Why does everyone say that homosexuality is a choice ?
Most of the scientific research backing it is just shitty correlation based social science studies which dont even try to give any explanation, on the other hand most hard science studies which work on brain developmental models seem to provide very little dataset proof. Only a few studies have been able to provide a good proof through data but those solely work on one the basis of factor by factor homosexuality (that is it only explains homosexuality in particular cases and scenarios like there being younger brothers and doesn't explain it as a whole).

Personally I think it's quite obvious that a person being homosexual is something in their brain (which might be too complex for us to detect yet) being different from a heterosexual person.

Now let's assume that homosexuality IS in fact a choice. This statement assumes that everyone's brains have an inherent sameness or likeness which allows people to make the 'choice' otherwise the starting point of the assumption itself will be wrong and the whole reason they make this statement which is to state that just because some people are different it doesn't mean that they are inferior (hence saying that gay and straight should be treated equally in society ) .

Therefore I as a person is bound to have the same common factors as everyone else. YET I as a straight male can't even think about another male with sexual preference in question, nor have I been ever able to. I as a person was never given the choice of choosing men over women nor did my parents ever force me to choose women. Can anyone point out at which point of a persons life do they decide if they wanna be a homo or heterosexual ? In fact just like all little boys we all made fun of that one boy who was close to a girl as having a girlfriend.

In maths, theorems from what I heard are the last lines of proofs; which are sequences of lines where each line is an axiom or a proposition that can be reached using inference rules on the previous lines.

So, can a computer be used to generate new theorems by starting with an axiom or an old theorem and randomly using inference rules? Can such a process lead to a useful theorem given enough time and computing power?

Once we run out of oil will many countries in the world revert back to an 18th century lifestyle with candlelights, horses and steam ships? It's unlikely we'll go back to nuclear power because of muh radiation, and only very rich countries would be able to afford solar and wind power.

I’m a pseudoscience-pleb and I have been thinking about this a lot recently; if videogames can in the long run rewire your brain and how you handle rewards and stimulation.

Basically, my argument is this.
In the Stanford Marshmallow Experiment we saw children given marshmallows, but told that if they did not eat it for a time they would be given another one. The kids were agonized by the test, many ate it, some took bites of it, others looked away.
But the interesting part about this experiment is that it was followed for 12 years, and they found the kids who could resist the marshmallow had done much better in life. Better careers, better income, more happy.

The people who play games like CS:GO, Overwatch or Dota 2 are the same as the kids who could not stop themselves from eating the marshmallow.
It is a lot of short-term gratification, and these game actively teaches you to enjoy short-term rewards. Quick goals. You gain a level. You gain XP. Things that stimulate dopamine rushes, and can cause addiction.
These rushes will in the long run deplete you from being able to have long term goals, and other videogames that are too slow will become boring to you. (Unless that person decides for themselves to stop).

However, it’s now harder to stop because a lot of these videogames rely on gambling mechanics like lootboxes. It is an addiction to these dopamine rushes, and since they seem to trigger the most when we anticipate a reward, not when we achieve something.
This means a game doesn’t have to be GOOD to be addictive, it just has to be addictive. This also plays into the “Sunk cost fallacy”, which means the more you have invested time or money into something, the harder it is to let go of it.

I think this does not mean ALL videogames are bad for you, I don't play Dark Souls but I think someone who does play it might be able to handle things better.
You know there's a goal, and your progress, even though it's slow, you can see that you're moving forward. Dodging and fighting a boss feels great. Failing feels like learning.
This would stimulate long-term rewards.
However, I think current videogames are mentally damaging people, and we already saw this with the previous generation addicted to games like World of Warcraft.

>>9129873
I actually agree. I have been addicted to league of legends for 7 years now. I estimate ive spent 5000-6000 Hours on the game. What do I have to show for it nothing. The games reset after about 45 minutes. I long ago stopped enjoying the game and played to feel that dopamine rush which becomes more and more rare but I play it more and more just to "kill time" and actively feel bad when I dont play it.

This addiction has placed huge stress on my social life, my relationship with my girlfriend. I perform worse at my job and often leave early or go in late or not at all because I want to play just "one game" that turns into 10 hours of gaming.

I have attempted to quit multiple times but never managed. I have written about this addiction many times but my brain tells me ohh you didnt play for a while. Now you can just enjoy the game again play one or two games with friends. Of course thats the lie every addict tells himself.

We need to actively protect our kids from this addiction. Now I am not saying everyone gets addicted no its obviously a complex interaction just as with alcohol where only 10% of users become problem drinkers (funnily enough I was also an alcoholic).

Anyway, I think the main problem is that these games are actively made to be addictive. League of Legends employs a horde of psychologists that shape how the game is designed to make it more "enjoyable". These games need clear warning labels as is seen on cigarettes. Furthermore, they need to acknowledge that a subset of users become problem users and need to facilitate treatment.

Anyway, I hope that at some point I can stop playing :). The difficulty is this game is also a major social interaction for me. Leaving it would mean leaving behind so many friends. It is the same problem faced by heroin addicts who have to cut off their old social circle of users if they want to get clean.

Anyway, yeah I think your right.

>>9129889
Thanks, it's nice to see someone agrees. Basically what caused me to wonder this is because I started playing Overwatch six months ago.
I'm an illustrator who makes art for a living, which means having to sit for hours and hours dealing with problem-solving paint and lines.
But since I started playing Overwatch I suddenly found it insanely hard to focus on painting and drawing.

As if every time I started to work I felt like, this just wasn't enough.
Usually what kept me drawing and painting was the idea of having a finished painting, but that is such a loose concept compared to "capture this point, kill the enemy, move the payload". It wasn't rewarding or stimulating compared to playing the game.

I also tried to quit over and over and kept coming back, because it would be a waste not to get the "daily xp bonus", and of course one game turned into 3-5 hours.

I'm curious if this not only causes addiction, but affects general mental health.
I became very immobile, unmotivated and felt tired all the time during that period and it took me some time to accept that I was actually suffering from depression.

I have heard that depression can be caused by how rewards and stimulation has been affected in your brain, and maybe this is me projecting things, but I've felt so much happier since trying to force myself to enjoy "long term reward" activities again like painting and reading.

I'm totally open to hearing opposing views though.

There's no doubt that a plant based diet is optimal for health, but how much meat should one be eating, if any at all?

I understand some nutrients (B12, creatine, carnitine come to mind) are only found in meat, but is it possible to supplement your way around this?

Yes! It is totally possible.

Creatine and Carnitine are synthesized by the body and B12 comes from soil bacteria. I eat whole foods plant based and supplement with B12, D3, Iron, and Algae Omega 3's, DHA, and EPA.

It's very easy to stop eating meat altogether.

Any med students out there able to give me a diagnosis? Before you state the obvious I'm in leaf land and my family doctor only practices 12 hours out of the entire week.

Primary symptom: Numbness and pain in left foot, most prominent in big toe. Soreness back of knee joint. Left leg becomes tired very quickly, way before the right leg. Symptoms showed 2 months ago.

Possible secondary symptom is difficulty sleeping regardless of how tired I am. I'm lucky these days to get 3-4 hours of sleep between shifts or during my off days.

I went through a job change earlier in the year which makes me way more active. I spend a lot of time walking around and going up and down stairs in construction boots. I work rotating day and night shifts.

Doctor suggested low b12 levels when she ordered the blood test so I've been taking b12 supplements for about 2 weeks

How can anything cross the event horizon of a black hole if the rate of time dilation there is infinite? Wouldn't the object heading towards it travel trillions of years into the future until the black hole had evaporated from hawking radiation? It just makes no sense

The outside observer would never see it. The blackhole is still a rotating spherical mass with a surface that attracts matter like any other gravity well.
>>
>>9126456

Time is relative. You could easily say that making an object fall towards the black hole makes everything else speed up. The object will still enter the event horizon, but >>9126557
is right to say that outside observers will never see it.

>>9126456
It all depends on the way that you observe it.

The first step is to look up big words to see if you're spelling them correctly.

Next, always put school first and try to build good relationships with your teachers. This means getting all your work done on time, finding the study method that works best for you, and showing your teachers that you're making a genuine effort to do well in their classes.

Start studying things you're interested in outside of school. Whether that means watching lectures online, or just browsing some wikipedia articles from time to time, get in the habit of reading about academic subjects on your own time.

This is an 18+ site by the way.

I was discussing with some friends about what if everyone died and one of them said the world's nuclear reactors would all blow up, is that true? How exactly does that happen?
6 posts and 1 images submitted.
>>
>>9133396
I doing think it'll blow up but it will melt down without humans to renew the cooling process
>>
>>9133396
Reactors blow up when the coolant becomes too hot and boils into steam, too much pressure ruptures the containment vessel and produces an explosion of steam. In the case of Fukushima it was caused by normal seawater being poured into the reactor and boiling off into a flammable gas which if I recall correctly was ignited when the fuel rods became exposed and came into contact with the gas.

Modern reactors wouldn't blow up, they have multiple backup safety systems such as liquid poisons (a liquid is injected into the reactor which damps down the reaction and stops it immediately) to kill the reaction if the reactor begins to melt down. Those safety systems are activated independently of human control or computer control. If they don't overheat and they just keep running, eventually the fuel rods will degrade and cool off, eventually rendering them dead and the reactor will stop producing power.
