Why did Russian women evolve to have huge as fuck tits? Likewise, why east asian woman cannot into jugs?

IQ testing

47 more posts in this thread. [Missing image file: measures.png]
Hey /sci/! This IQ test is quite reliable for its class, why not give it a go and compare the stats to the other /sci/entists? http://www.iqtest.dk/main.swf The timing is mostly generous. And only the last 9-5 questions are hard, depending on how good you are. So give it a good try!

Why aren't airplane wings sharp like a knife, wouldn't it cut through the air better? Is it it because it wouldn't create any lift, or maybe it just wouldn't glide properly?

if without then

Example of "if" without "then" error in a statement: >If he was five years old in 1988, how old is he now? He either WAS or else WAS NOT five years old in 1988; and if he WAS, then SAY SO: >He was five years old in 1988 – how old is he now? If for some mad reason you DON'T KNOW whether he was or was not five years old in 1988, then use "then" as a conditional qualifier: >If he was five years old in 1988, then how old is he now? IS THAT SO BLOODY HARD? Thank you for your attention.

"Is E=Mc2 a sexed equation? Perhaps it is. Let us make the hypothesis that it is insofar as it privileges the speed of light over other speeds that are vitally necessary to us. What seems to me to indicate the possible sexed nature of the equation is not directly its uses by nuclear weapons, rather it is having privileged that which goes faster." Does science need to check its privilege?

Hi /sci/, What I've never really understood is the extrapolation that finds place in the WAIS: when you have a 145 fluid IQ and a 145 crystallized IQ, your full scale IQ would 160. How does that work? How can they extrapolate with certainty 1 whole deviation? With kids like Barnett this seems even more speculative as with his 170 IQ score a double extrapolation has taken place (also the child-adult score extrapolation). Does anyone have any hard facts or articles about these extrapolations or know anything about them?

I just did one of the coolest proofs I've ever attempted, stolen from the book whose picture I am using: Show that a ring R is semisimple if and only if R is the (finite) direct sum of left ideals L_i (simple as R-submodules) R = \oplus_{i=1}^n L_i such that for a set of orthogonal idempotent elements {e_i}_{i=1}^n , with each e_i \in L_i and \sum_{i=1}^n e_i=1_R it happens that L_i=Re_i for every i IT'S SO COOL!

Are there any stars that can be seen prior to their entry into the main sequence?

Prove me wrong.

Hey there /sci/ I start college in september and I just can't figure out this equation, Ive tried all sorts of things. After that didn't work I tried googling some tuts, no help there. And I don't have my books yet, Im required to do these to enter into chemistry. Anyone know the solution and can tell me the method for future reference? tl;dr I have to do this question or I fail

What field of study explores the dynamics of the development of taste over a persons life history and experiences

How should humans travel to space? Should they use rockets? Should they use space planes,or shuttles? Should they do something exotic such as space elevator? Or perhaps a combination of multiple things? Also should Humans consider mass production of space vesicles,versus spending billions on a single program to produce 5 or so shuttles/space craft/what ever.

hey /sci/ im planning on going to uni next year and am unsure about what kind of career to pursue i love physics (especially astro and nuclear) and thoroughly enjoy mathematics at school, any ideas on courses and jobs you think i should study, also general what do you do for a living thread. pic unrelated

I see these threads pop up on various forums on 4chan where people ask a ton of stupid/easy questions so I figured maybe /sci/ could use one too. Use this thread to ask simple questions that you want answered but you don't want to make a thread to ask, and also to answer other peoples questions! I'll begin: How do magnets actually react? I understand how magnetism works but if two magnets are close to eachother how are they "aware" of eachothers presence? The magnetic fields, right? But what particle exactly allows the two to react? Photons?

What calculator does /sci/ use?

Just curious what calculators /sci/ uses. I love my TI-83+ silver edition since I got it when they came out, still serves me well.

Momentum and Energy

18 more posts in this thread. [Missing image file: Névtelen.png]
I have a question. There are 2 masses one with v speed, the other with 0 speed. The first start pushing the other untill they are at the same speed. The momentum must be the same before and after. Before m*v After 2*m*v/2 But the Energy of the system has to be the same too Before: 1/2*m*v^2 After: 1/2*2*m*(v/2)^2=1/4*m*v^2 if the new speed is v/2 and that is not equal. What is wrong here?

Let's talk about Fluorine. Fluorine is the most reactive and most electronegative of all the elements. SO BOW DOWN This shit doesn't exist in nature in it's elemental form because it's so reactive but it will FUCK YOUR SHIT HARD if you attempt to RELEASE THE BEAST. Don't ask me, though, just ask all those stupid scientists that died trying. Hydrofluoric Acid; put it in glass Pyrex it's like FUCK THAT SHIT and eats right through it. Iron? No problem. Lead? Fuck you. Fluoroantimonic Acid; strongest acid know to man. You even think about touching this shit your whole family dies and your stupid cats. ALIEN BLOOD EAT YOUR HEART OUT. You can only store it in a Teflon container, which reminds me.. Polytetrafluoroethylene, aka Teflon; one of the most corrosive resistant and stable compounds known to man. Suzy homemakers reading this better check their panties. You can't fuck with this shit OH, I FORGOT, unless you have... PERFLUORODECALINE; this shit DISSOLVES teflon. LOLZ, YOU NEED FLUORINE TO BEAT FLUORINE. Bitches. Oh, and you can dissolve a shitload of oxygen in this and BREATHE LIQUID. Well, at least until you don't die from carbon dioxide build-up. But FUCK YOU only pussies die. Uranium Hexafluoride; you need this to isolate U-235 from naturally occurring Uranium to make an atomic bomb. Yep, that's right bitches, without fluorine all those stupid gooks would still be alive. HA HA! LOL, FLUORINE FUCKS YOUR SHIT NIGGERS AND YOU KNOW IT

Found this in ontario... Can anybody name anything off this coin to the right? Names of people?
