Why is it that stem majors (i.e. Biochem) get rejected from folks like Pfizer, DE Shaw Research, Hospitals, etc and they instead pick folks from target universities with irrelevant majors like Literature or government from places like Princeton?

What would you recommend a stem major with no job to do? Assuming every no he gets from any fucking entry level job is given an excuse of "under qualified" and "over qualified"

I'd ask this on biz but the auto response is to suck dick

Do what those fags should have done. Go into finance. All those fuckers at Goldman Sachs are easily impressed with big words like Polymerase Chain Reaction.

I'm not joking. I got a BS in biology and I got hired by Morgan Stanley because they're easily impressed by you using big words and name dropping.

Also Pfizer sure as fuck doesn't hire someone with only a tiny bit of experience in chemistry just because they came from Harvard. Also I'd suggest, if you want to work in a hospital, to get your medical tech license. Literally the only way they're even going to consider you.

I would say I am still lazy. I have finals next week and I have 2 tests this week yet I spent my weekend fucking my girlfriend.

From this I think that no one is really lazy, they just have a bad attitude that is a result of the system not respecting them, therefore you stop respecting and caring about the system, like I did. Now I put as little "effort" into math but now I am pretty good at it, simply because now I actually can enjoy the environment I am in.

Seeing my 'talent' my professors now even question me about not going into the math olympiad ever and question me about why my grades in math were so shit (so shit I was almost not even accepted) but now I am the top student in every class.

I am still salty though.

IF I COULD HAVE STUDIED 5 HOURS OF MATH AND 4 HOURS OF PHYSICS EVERY DAY BACK IN MIDDLE SCHOOL AND HIGH SCHOOL I WOULD NOW BE THE NEXT EINSTEIN, I WOULD HAVE 50 PHDS AND 10 WIVES.

50 PhDs and 10 wives... all taken from me because of a shitty and broken school system that does not let me pick my classes. Fuck school.

In a thermonuclear reaction shouldn't the core be the hottest part with the coolest part being the surface? The observation are contradicting this so what is the actually happening here?

The density rapidly falls off after the point of hydrostatic equilibrium (where gravity = gas pressure), but you've got nearly the same energy flux passing through.

Same energy + much, much fewer particles (~1000 times less dense, IIRC), means much, much higher temperatures.

How do you get [math]\epsilon = a-b[/math]?
Why can't I just do the following:
[math]a-b > 0[/math] (1)
[math]b+\epsilon > a [/math] (2)
(1) + (2);
[math]a > a[/math]

This is an example in the book Mathematical analysis, a straight forward approach in case you wonder where I get this.

>>8491452
(1)+(2) gives you [math]a+\epsilon > a[/math] which is correct [math]\forall \epsilon > 0[/math]
>>
>>8491460
Sorry I was sleepy. I reallized how stupid that was after I hit the post button.
But how do you get [math]\epsilon = a-b[/math] anyway?
>>
(mistakes were made. Now I need to keep trying until it works)
From the first hypothesis that [math]\forall\epsilon>0, a<b+\epsilon[/math]. So author is choosing [math]\epsilon = a-b[/math] to give a contradiction for this 2nd hypothesis.

like the slightest tilt of the earth drastically changes weather but mars is forever away and is relatively habitable

like the earth is spinning in place perfectly while spinning around the sun perfectly wtff

like things are supposedly weightless but they have this power called gravity that moves other things wtff

like tfucking BLACK HOLES?

like the sheer size of it and the fact that we are supposed to believe that lol

like the notion that gravity and time and velocity are all somehow related wtf?

like the fact that we've been watching space for so long and we've never seen a huge explosion or some shit and gone "wtf was that?"

WTF IS SPACE

Why do you even need to know its completely irrelevant to your life. Just go to work, keep your head down and buy things that you think will make you feel good.

I would guess that you're probably about 16 and not doing very well in high school. Most of your questions are easily explained by college physics 1 and basic calculus, and half of your questions/statements are not correct/misinterpretations.

Not trying to be a dick but there really isn't much of a point in trying to attack all these points when you need to finish highschool and take a couple college STEM courses to grasp these concepts.

im an economics grad wtf

im not trying to argue with anyone i just have some simple ponderings about the nature of our universe it seems fucking inexplicably well crafted and infinitely more complex than i ever knew now that i've given it some thought

some simple explanations for some of this stuff would go a long way

hey /sci/! I'm a fucking retarded artfag that
hasn't done math in years. Give me 100 equations that slowly increase in difficulty,one suggestion each! so that even a goober like me can get somewhere in life! dubs and I'll add your suggestion to my list, trips and I'll quit while
I'm ahead and fuck off back to my gender studies thesis.

Don't know. Though some programming (like compression, error correction, encryption) do need a lot of math.

The reason I ask is because I'm trying to come up with hypothetical curricula.

So for example, instead of just, say, introducing good old quadratic equations in a vacuum, and getting the inevitable 'what would I even need this stuff for anyways', I can just have problems of praxis that just so happen to also demand the principle in question, too (like calculating the ballistic trajectory of a reaction engine on its way to blow up dirty commies and brown people using a few of the most influential variables).
