>"smart in other ways"

how does unevenly distriubted intelligence develop in people?

is it true this is more common in people with older parents?

do you have exceptional ability in one area and borderline deficiency in others?

>do you have exceptional ability in one area and borderline deficiency in others?
Yes. From what I've seen, many people are this way.
>>
>>8196735
Take super-autist for example.
He's smart in math, chemistry, high-iq, learns everything super quick.

But he cannot socialize for the life of him.

Intellectually smart
Socially defunct

Socially smart people are good at manipulation, getting what they want out of others, persuasion, etc. High intelligence and social ability and you could almost be like a spectator, getting everything you want, and dropping it just to change dynamics and see what happens.

>how does unevenly distriubted intelligence develop in people?
Usually laziness and lack of effort / any environmental means to realize what ties things together.

Less commonly a hard mechanical cause.

Hello anons, I am looking for the name of the type of habitable planet which is only habitable on the outer rim of the planet because of rotating sideways to the sun...?

What's the consensus medfags? Is this stuff harmful or beneficial to health?

Does it depend on the dose alone?
59 posts and 4 images submitted.
>>
>>8199337
>Harmful
Kind of, and mostly. Especially with chronic consumption.

>Beneficial
In no meaningful ways. The concentrations of beneficial compounds found in red wine are minuscule and occur alongside a number of other metabolic byproducts that give a good portion of the human headaches and much worse hangovers.

The human body is a complex machine, and ethanol and its metabolites net out as toxins, regardless of dose. Booze is for changing your mental state and perception, ie, as a drug. No more to be framed around "health" than dextroamphetamine.

Also, evidence shows it strips dendritic spines and changes their formation behavior afterwards, especially with teenage drinking. Which I did plenty of, but don't really care as a whole.

How do u explain the reduced mortality from cardiovascular disease in moderate drinkers compared to non-drinkers even accounting for exercise?

Any autodidacts in here? Tell me your experiences in self teaching. Personally I have had much better learning from teaching myself than any time I've spent with teachers. I taught myself music theory in middle school and how to play about 4 instruments. Then in high school I taught myself differential and integral calculus, some of the basics of quantum mechanics, and now I'm teaching myself linear algebra.

>>8199387
My issue with self-learning is that I stick with non-technical stuff. I do have a very broad range of knowledge.
>>
>>8199387
it's not very efficient to self teach in the long run. unless someone knows what he's doing is helping you or giving you advice, it's very easy to get lost

that said, it's better than nothing. so keep going bro

I'm a math major at a shit school who's been teaching myself math outside of what I'll learn in my undergrad. So far I'm in the middle of Galois theory, am learning Dynamical Systems, advanced linear algebra, and Analysis I haven't done yet. In the past I taught myself advanced calculus and discrete math before touching the material in university. In the future I plan to teach myself pure math on the side while pursing applied math in grad school.

What's the best entry level chemistry work/textbook?

Ive looked into the Chemistry Workbook for Dummies, which gives assignments and practice as well as covering simple chemistry, but something that covers more of an in-depth scope is appreciated.

(Microbiology and pathology books also accepted for fun)

So what happens when the ISS is decomissioned in 2025 ?

Do space agencies nowadays have the budget to put something back up ?

Will it be the end of continuous manned spaceflight ?

The space shuttle was the end of manned spaceflight. ISS is just like the tatrail of a headless snake still flopping about. It's up to private companies now, unless there's a major change in the world's priorities, that I just don't see happening.

>>8199847
I take it you've not been keeping up with space news. There's no longer big hoopla in mainstream media but the private sector and Chinese are sending shit up constantly including people.

Because of deep learning which lets you solve harder problems. It's also worth mentioning that there are a fuckload of huge frameworks for working with deep neural nets as well as nvidia libraries and shit.

Why do our alcoholic drinks contain ethanol, and not isopropanol?

A quick Wikipedia search verifies that both substances have almost the same lethal dose.

On top of that, isopropanol is metabolized to acetone, which is not only much less toxic than ethanol's metabolite, acetaldehyde, but non-cancerous as well.

What am I missing here?
