I taught English at a community college for a semester. One student just turned in a picture of Trayvon Martin repeated across 20 or so pages with no text. I don't need to go into detail about this student's particular phenotype.

Yes, it was just as lame as it sounds, and
I never saw so much bullshit in my life, before or since.

Where do you high intelligent guys get your ambition and motivation from?

I am not genius, but definitely above average.
So I could definitely be not a complete unsuccessful person.
But, I really dont have the drive to become an engineer and get a career.
I think that it is way too stressful. Studying all day and afterwards working all day.
The 9-5 is already to much for me. If you include the preparation ( eating etc...), then there really isn't too much leisure time left and it is quite stressful too.

Why do I just want to live a more minimalistic lifestyle with a lot of free time, healthy lifestyle so I can pursue my hobbies or even just smoke a joint and watch a movie?

Is it brainletsyndrom that I have no ambitions?

Maybe don't force yourself to do the things you don't want.
>>
You could be depressed, but the answer is that people with career ambitions were brainwashed/conditioned into them. Their lives are certainly pointless and nothing they do matters, but society and their parents tricked them from a young age into believing otherwise. So they develop dreams like "I want to be an engineer!" that seem alien and strange to a person like you because being an engineer or whatever else is ultimately meaningless and even sounds pretty fucking awful. It doesn't matter and everyone dies as nobody after the cosmic blink that is their life, so just do whatever feels right to you and ignore social pressure to be "successful." With very few exceptions, successful people are just obedient.

How to be like ramunajan? I'm also indian, with a horrible environment.

I'm more handsome but I think old Ramu's got the mental advantage. Is determination enough, or does genetics determine everything?

Determination can bring you far, but you will need genetics and talent to become the cream of the crop like Ramanujan.

If you had to ask this question, then no, you cannot be like him.

There are some BASED mathematical logicians like Harvey Friedman, Stephen Simpson, William Gasarch, George Boolos, Theodore Slaman, etc.

It almost seems like a political decision to ignore mathematical logicians.

All of those logicians seem to have something in (((common))), but I can't put my finger on what it is. ;)
>>
>>9038940
what might that be anon
>>
>>9038921
Logic used to be a nice meme because the incompleteness theorems basically went against the intuition of every mathematician so people started admiring these logicians who could prove new statements about the nature on mathematics in the hope that one day one of them would prove something that we liked.

Then none of that happened, but we saw how practically meaningless the incompleteness theorems were because the complexity of our theorems has gone from 0 to 9001 in just the past century and we are still doing good proving everything around us, so now the interest of the general mathematician has gone back to usual mathematics: number theory, geometry and algebra.

You are a relic of the past.

that a targeted prostate cancer therapy?

allegedly you cant feel gammas from a reactor; if i stand out in the sun ill feel my face tingle as it burns and i assume thats photons interacting with my skin cells? if i get blasted in the face by gammas why wouldnt i feel it?
>>
>>9038440
Yes, in the case of the image, it is an interstitial, low dose rate radiotherapy modality for the treatment of prostate cancer.

Other applications of brachytherapy (which include both low dose rate [LDR] and high dose rate [HDR] variants), include the treatment of breast, skin, lung, liver, GYN, and other varieties of cancer.

It can also be used intravascularly, to minimize restinosis following angioplasty, stent insertion, etc.

deviated septum.jpg
28KB, 479x360px
All of my life i've been prone to daytime sleepines, depression and attention issues (even tough im finishing college). But recently i've been diagnosed with a deviated septum which blocks airflow and casues sleep apneas (sleep interruption) both of these supposedly affect cognitive functions.

Do you know of serious studies that analyze this? i would also like to know if i may someday acquire normal brain functioning or if the damage is already done.

You will have to accept the fact that you're a brainlet.

>>9038299
deviated septum is unlikely to have the significant effect on your cognition that you think it does, even if there is an (small) effect. people complain of these issues of sleepiness and attention all the time. its normal in some sense and might be related to where your life is at at the moment (are you where you want to be?). some of the best consesnsus is that the biggest way to improve cognition is to improve your life circumstances. social life, excercise, the right job. the only way to beat your issues is to put real planning and effort in to seeing what youre bad at and how you can alleviate it. even more so, looking at your goals and seeing what is reasonable or unreasonable. your issues might be predisposed to your genes. they might be partly to do with your septum (through sleep) but see a doctor, not 4chan.

http://www.annualreviews.org/doi/abs/10.1146/annurev-psych-113011-143750 a supporting review by an expert. training by e.g. brain training is not conclusive and is very inconsistent. it is probable that these only have near transfer and so aren't useful atleast in a significant sense. meditation isnt discussed a whole lot though but from my intuition it seems better than brain training (e.g. n-back) because it seems to be working on cognition in a far more ecological context, or atleast has the potential to.
