because it has a lot of debt to pay off
it costs a lot of money to get built these days

Undergrad math student here, I'm about to take babby's first real mathematics class focusing on proofs and such. We're to use this textbook, but I hear that it's sorta shit on its own. Any recommendations for a good book to start self studying methods of proof and real analysis so
I don't embarrass myself this coming semester?

Last year physics undergrad here, took real analysis as an optative, one of the worst experiences in my life. I'm too brainlet for that, bye
>>8531954
It's pretty overkill to spend a whole book just learning proofs. Your introductory textbooks will go slow enough that you can learn it through those.
If you understand what a contrapositive is (most undergraduates fucking hate contrapositives for some reason) and how proofs by negation/contradiction work (on the other hand most undergrads try to do everything by contradiction) you're ahead.
Abbott's understanding analysis is a pretty nice book that takes great care in explaining the basic mechanics of analysis at a fairly handhold-y level (which is what you want).
Another helpful thing to look at is Counterexamples in Analysis, which is not a text but rather just a long list of counterexamples to things that might seem true. Doing lots of counterexamples helps stuff feel a lot less arbitrary because you can see what goes wrong when you change assumptions or aren't careful.
General advice: know and understand your definitions precisely. You will fall on your face otherwise.
Try to engage with (think about) the material on your own. Pisses the hell out of me seeing students so dedicated to being a sponge that they can't come up with f(x) = 0 as a counterexample to something.
someone explain this fucking equation to me.
20 divided by 5 = 4
2 multiplied by 2 = 4
why is there no function between the 20/5 and (2x2)?
google just adds the "multiply" symbol there. why does it assume that?
also, how the fuck do you even get a "1" as answer?
>>8531938
I would have a hard time taking seriously someone that says 1 is the answer to that problem.

Theories of cognitive evolution suggest that social species are also smarter.
Species with proportionally larger brains also tend to larger social networks.
Complex social structures are a sign of intelligence.
How come, then, so many intelligent academics throughout the ages have been complete social outcasts or otherwise wondrously socially inept?
For yourself, why do you have so few (if any) friends?
Probably because the cognitive tasks required to be a social organism are not necessarily the same as those required to be a human calculator, coupled with plasticity in cognitive function, especially when you consider differences in rearing patterns between individuals.
Social species like crows and scrub jays typically need a fine tuned memory to be able to navigate social interactions; keeping tabs of who helped you and who hurt you, who you can and can not depend on, and being able to remember where food caches are stored, ect.
Also bear in mind that for many more complex social organisms, early life is typically a learning period where they gather skills needed to navigate their social environment. Those individuals that bury themselves in studying or are otherwise highly isolated early in life are also likely to learning different skills and talents that would prepare them for a significantly different environment (such as one without friends or social networks) than those children who are highly prosocial or have access to vast social networks that they navigate regularly.
TL;DR: Behavioral plasticity + social isolation = more time for studying and less time playing with friends = higher scholastic achievement = academics.
To answer your final question, I have no friends.

how is it possible for people to get their master's or PHD before they even turn 20?
Do they just study at home and pass exams at a university to get their degree?
>>8531912
Nope, they're usually just a meme. Universities just give them this shit in hopes that they stick around the university for the rest of their life.

It's a combination of being brilliant and having parents who recognize that you're brilliant and shove textbooks up your ass from age 4 and put you in accelerated programs so you finish high school at 13
How can we heal the ozone layer? Or is the hole going to keep getting bigger and bigger?
>>8531637
It already is healing. So long as we avoid fucking it up again, it should slowly come right.
>it should slowly come right.
But very, very slowly. CFCs are class I ozone depleting substances, HCFC is class II, less effective.
>>8531637
We already did something about it.
scientifically, what is wrong with eugenics?
1.you are in the dark as to what genes you are trying to amplify
2.you are in the dark if they are being amplified at all
3.it's too slow
loss of genetic diversity is a main one. an engineered society would be less able to adapt to a changing environment.

How do i stop being a brainlet?
studying
You have to make knowledge your hobby. It's like a fire under your belly. Suddenly school isn't just work, but it's your life. Knowledge isn't just something you use to pass tests it's something you internalize and apply. When you find that fire suddenly you'll find yourself reading books on mathematics, not because you need to, but because you want to. You want to internalize the information and use it for your research or for something you're making, or to discover an application for it. Or to simplify a problem you've encountered.
Until learning becomes an insatiable hunger for you you'll always be a brainlet.

Heres a challenge for you brainlets.
Give me one use of solar panels that no one has thought of
>pro tip you cant
>>8531366
you can barbecue on them ;^)
>>8531366
Well solar panels were invented to only take advantage of the sun's energy so unless you MacGuyver your way into some other use then go a head.
DESU if Solar Panels were simply made more efficient that would be a huge benefit but currently they only produce about 20% the energy they take in.

>tfw to intelligent to believe in mainstream myths about oil shortages
Petroleum is NOT from fossilized organic material. It is something that the Earth's mantle produces from rocks. There is a nearly infinite source of oil into which we have yet to be able to tap. It may become more expensive to access the sea of abiotic oil, but we will at least have oil for as long as we exist on this planet.
>Experiments under high temperatures and pressures produced many hydrocarbons—including n-alkanes through C10H22 [this is gasoline]—from iron oxide, calcium carbonate, and water.
https://en.wikipedia.org/wiki/Abiogenic_petroleum_origin
Theoretically we may one day be able to put materials down there, like our garbage, and have it turned into petroleum.
Biotic oil theory was never really proven. Its main basis is certain biomarkers that are similar to plant biomarkers, as though two molecular shapes can't arise separately.
You've been lied to, and the lie serves (((their))) interests. Everyone must believe that oil is finite for the price to be so high. Oil is the most valuable substance to global civilization. If it were discovered that it is virtually infinite, civilization would continue growth trends all the way to Mars. Everyone would be rich instead of just a few. Instead, nihilistic panic is what they want global society to experience as they ensure our economic slavery.

you sir are a boob
>How oil is created has nothing to do with the fact that oil is finite
It is though. Abiotic oil theory states that the mantle produces oil. If that is the case, then the oil we have drilled so far comprises the part of the mantle's oil that seeped up. Whatever seeped up must be a smaller part of a greater whole. So abiotic oil theory being true means there is a vast sea of oil yet to be accessed.

Seismograms and numerous experts in this area warn that this abundance of earthquakes could be a misleading sign that something serious is happening in the bowels of the Earth. It is a global disturbance in the core of our planet that causes an unknown vibration.
