What if I told you the sea levels are rising because we're getting ready for a fat deuce of an eruption from the earth's core? The land is sinking slowly because the magma in the core is now coming out at 10-20 cm every century. We still have a long was til it reaches the surface, but when it does the earth will see an eruption far beyond all others, covering the earth is magma, followed by the dissolving of the earths magnetic shield, and essentially making earth a ball of no life if we don't escape.
Discuss.

I would say you are a moron because the core is not where eruptions come from, for starters. And that is just for starters.

But what if I told you, they were?
The earths core has a lot of hot shit and I would say all it would take is a large tremor-esq earth worm to poke a hole in the core bubble to make it begin to escape.

There is still magma being produced from ocean faults, and you overestimate the pressure coming from the core.

Jacques Herbrand was a young mathematical genius (died at 23). He was world class and impressed the greats at the time such as Noether, Artin, etc. The wikipedia article on him and his varied mathematical work is lacking, but I've heard legendary stories about his brilliance from mathematics professors and read similar accounts obscure passages written about him on the web.
"He was awarded a Rockefeller fellowship that enabled him to study in Germany in 1931, first with John von Neumann in Berlin, then during June with Emil Artin in Hamburg, and finally with Emmy Noether in Göttingen."
Emmy Noether said of him "I can't get Herbrand's death out of my mind."
Who are other obscure mathematical geniuses that died young?

"He is considered by many to be the greatest mathematician of the 20th century."
Any citations on this? I'm a mathematician and never heard of him, until recently. Looks like the article is written from category theorists' POV, who assume their theory is the most important thing in mathematics, when it clearly isn't. It is pure POV. His list of achievements doesn't look all that significant, if you consider that most of them are in some obscure part of mathematics. Half of his "major archievements" don't even have a Wikipedia article. The more I look at it, the more it looks like some sort of fraud, or an instance of extreme fanboyism.

It is a quotation from the Bhagavad Gita:
Tell me who are You in such a fierce form? My salutations unto You, O best of gods, be merciful! I wish to understand You, the primal Being, because I do not know what is Your mission.
The Supreme Lord said: I am decome death, the destroyer of worlds, out to destroy. Even without your participation all the warriors standing arrayed in the opposing armies shall cease to exist.
Therefore, get up and attain glory. Conquer your enemies and enjoy a prosperous kingdom. All these (warriors) have already been destroyed by Me. You are only an instrument, O Arjuna.
The "am become" construction is a bot if a transnational affectation, it is archaic grammar, used to make the age of the words come through.

Can it be that the only limiting factor in learning concepts is time or are there concepts that are too complex to be ever understood by an average perosn?
If so, what is the specific cause that makes something unlearnable?
Complex concepts can be broken down to simpler ones, and you can keep breaking them down the chain as low as you need, meaning complexity in itself should not pose a problem ever. You should be able to explain anything from complex economical theories to advanced mathematical theorems like this. The only obvious limit to this is time - the amount of time it would take, depending on the individual, of having to go through the entire chain up the pyramid of complexity of concepts. The less capable the individual, the lower you'd have to start - the more time it would take.
But is that all there is to it? Or is there something less flexible than time stopping people from being able to understand something? Something like simply the capacity of keeping the simpler concepts in mind when learning the harder ones. Basically like you have to be able to hold at least two cards in hands when building a cardhouse - you cannot do it one by one. Can this be the difference between understanding a concept and failure - that less capable people simply lose track of stuff when dealing with multiple things?
Essentially the answer to these questions would determine the conflict of discipline versus ability and their relationship to success.
Pic unrelated.

Another potential limit is memory but the memory capacity of the human brain is very flexible and can contain enormous amounts of information. So just like with time, it's not really a 'hard' limit, so to speak.
Time isn't a hard limit because only a small fraction of our lives goes towards study so we have a ton of room to maneuver.
Ideally I'd like to find out what's the 'hard' cause for things being unlearnable. One that cannot be ignored or improved as drastically as with time (a lot of free time to utilize, discipline) or memory (huge innate capacity, practice). Assuming there even is one.
>>
>>9064930
I'd say it's just working memory. You may be able to piece-wise break everything down but you won't be able to form a cohesive picture because your working memory isn't good enough to store all the pieces at the same time.
>>
>>9064960
>working memory isn't good enough to store all the pieces at the same time.
Is working memory innate though?
Or could it be that your ability to mentally juggle various things simultaneously merely depends on how familiar you are with each piece, allowing you to rearrange them faster to form new understandings?
What if intelligence just boils down to some sort of curiosity that makes a person read and learn about things? Not necessarily all the time studying behind a book, but even just small tidbits here and there. What if that's what makes them intelligent - the fact that they just have a wide horizon, making them feel more comfortable adapting to numerous different challenges? Like having a bigger set of building material to choose from would allow you to build a better house?
Most probably there is a working memory limit, though. The question is - is that really what it generally boils down to, or could it be something else eg curiosity?

How hard is a Math major? I know Physics and EE are considered hard, but where does math rank on the STEM list. How far into math can one get if their i.q is 135, and what's the highest GPA they can get? 120 iq? 110? 100? etc
Why are math GPAs usually lower than other STEM majors? Is it because people apply without having any knowledge as to what higher math is?

How hard is a Math major?
It's trivial. The proof is left as an exercise to the reader.
>>
I can answer this though
>Why are math GPAs usually lower than other STEM majors?
it's because math profs have a more precise grading policy and they stick to it. It is also easier to justify that grade when some brainlet starts whining about getting a low one. It's the same reason why STEM in general has lower GPAs than non-STEM.

brainlet here, did number 51 for about 10 times yet the solution kept giving me
y = -16 and I know for a fact that ain't the solution.
I provided the LCD which is 20, got rid of the fractions, distributed, just don't know what to do next since it'll give me the same wrong solution.
It sucks being stupid.

If chinks are so smart, why weren't they able to develop a better language?
Every other culture in the world was able to create an alphabet of 20-30 characters that can be combined in various ways to represent nearly anything. Chinks, however, in their quest to develop a system of recording and transmitting information, end up with thousands of pictures that take forever to draw, and, if that isn't enough, chink languages are tonal, meaning a bunch of the words are phonetically the same, but have a different meaning based on whether you keep the tone of the vowel sounds constant, raise it, lower it, raise it then lower it, lower it then raise it, etc.
You'd think that for all of their "intelligence" they'd have a more efficient and less convoluted clusterfuck of a communication system.
Discuss.

There is their language and they're very different from ours phonetically. Where do you think people get the idea to wear out words like that? I wouldn't read to much into it because I've read that this isn't a very important thing. I mean, bear with me, even a big ugly black bear has to alter tone when making the same roar.

Japanese hiragana and katakana are literally "sound-it-out" (the symbols represent the actual sounds)
The existence of spelling-bees should tell you who has the worst language.

Econ question:
How does immigration affect a society that has a fixed money supply?
I'd guess that the citizens that were already there would benefit, because they already have money, and the new immigrants are in need of money.
In other words, the citizens as a whole have a monopoly on the money, and the immigrants are at their mercy.
But my intuition also tells me that if the market were competitive, then maybe the citizens wouldn't benefit at all.
What do you think? Am I missing something?

If there is a fixed money supply then immigration is bad because there are two cases
Case 1: Immigrants come in, but they get none of the money (for example, if no one hires them)
Now you have a huge population of homeless people, some of whom will turn to crime because they have no other option to survive and now your native population suffers from the increased crime rate.
Case 2: The immigrants get money (they get jobs)
Then, as the money is fixed, this implies that some of your native population lost money. Now a subset of your native population is angry because their social status was lowered.
This is why immigration only makes sense when immigrants can serve to increase the amount of money a society produces. That is why we generally want to immigrants with PhDs, and immigrants with experience. Immigrants that do jobs that no one else can do are drivers of new income in a country. But getting uneducated manual-labor worker immigrants will just upset our own manual labor worker native population.

There is no country on earth with a fixed money supply, so this is not worth thinking about.
