What do math majors even do besides teaching and "may I take your order please"ing?
I know it's a meme but I'm genuinely curious.

>>9033618
Physics is better it has more applications than pure math meme

math is probably the harder one for physics majors

two big ones are actuarial science and cryptography

yep, just like circumcision is for lazy assholes (ameicans) who don't want to learn basic hygiene

I'M NOT A FUCKING YANKFAG.

also the american imperial system is not the actual imperial system fyi

>>9033609
Or maybe we don't want to waste our time with unit coefficients, as seen with basic force calculations; and stupid fraction measurements, as seen with the inch. When will you Americucks accept that the metric system is the more efficient, and therefore more intelligent option.

that would be R- right?

>>9031941
We're removing the stuff attached to R to just get R remaining (R is generic hydrocarbon)

Simply use an hydrophobic molecule as a ligand to the hydrocarbon.I know ethylene is not water but its structure kinda close.

2 eyes = stereo vision and depth perception. Also for prey animals the eyes are often on the sides of the head, allowing for a wider FOV

Not all animal have noses in the same place, and many animals have no "nose" at all.

As for mouths, same as above.

>>9031436
maybe search symmetry in biology in wiki but maybe something to do with the idea of goal-direction, heading, so they have those evaluative senses toward the front parts of the animal (including things like hands and feelers). maybe nose, ears, mouth, eyes developed on head because its efficient i.e. close to the brain?

I discussed this with a bunch of friends while doing drugs, we agreed on 99 percent

>>9029527
Agree on what? Can you explain your reasoning?

>>9029524
Almost every alien I ever saw on star trek was humanoid therefore 100% yes Q.E.D.

Since none of the previous problems got solved I'm going to repost them:
1. >>9023709 (simple but tedious; linear algebra)
2. >>9023767 (simple but requires an advanced background; category theory)
3. >>9023781 (simple but there's a catch; arithmetic)

And adding two more to the list since the other anon who used to post problems seems to be MIA:
4. Let [math] 3 \leq p < n [/math] be natural numbers.
What is the maximum area of a [math]p[/math]-gon inscribed in a regular [math]n[/math]-gon (of a given area)? (harder than it reads, but tedious after you figure out the key aspects; analytic geometry)
5. Let [math] \mathcal{M} = \left\{ M \in {\mathbb{R}}^{n \times m} \mid MM^T = I_m \right\} [/math]. Prove that [math] \mathcal{M} [/math] is a manifold. What is its dimension? (simple but tedious; differential geometry)

Pick your poison! (Feel free to ask if you need any hints or clarifications on how to swallow it.)

No such thing.

>>9026508
is the max area p-gon an (n-1)-gon where you connect two adjacent vertices of the regular n-gon?

Probably not with that meme-machine you posted. The most surefire way is still ITER. But that shit takes fucking ages because a bajillion countries need to feel like they're contributing something.
If we get Fusion faster than that at all, it's probably because of projects like Tokamak Energy or what MIT has been planning for a while. Projects trying to build much smaller machines using recent tech superconductor tech that ITER didn't have available.
There is no guarantee that this will actually be a really workable solution, though.
Also even if they actually achieve enough net-energy-gain in a smaller machine than ITER, we'd still need a lot of research into the blanket and material technologies to make use of it. IE how to actually extract the energy from the reactor and how to reduce nuclear waste from activated reactor components.

What should I study so that I can work at a place like DEMO when they finally come online, /sci/?

ITER is planned to have finished construction around 2020 and will go online around 2024. If this works and becomes a viable power source, oil, gas and coal will be obsolete.

Can't wait for Muricas metaphorical jaw to drop when they realise that they can't get any money from oil anymore.

Because of people like you

Because there has been huge spillage of /pol/ and /b/ on this board. Just look at the meta thread that's currently up. Half the people in the they legitimately want off-topic posts to be considered fine and normal for /sci/.

Also this thread is not science/math. Remember to politely sage

>>9035926
The "go back to /pol/" spammers are a worse problem than /pol/ crossposters

That guy did not had autism. He simply had a prolonged case of lack of women.

See, let me explain you the cycle of men

>Man is born
>Man realizes how his penis works
>Man wants to put inside vagoo

Case 1:
>Man is attractive and can get vagoo
>Man get vagoo, become Chad
>Man never evolve and just stay as a typical Chad.

That isn't the case of Chris though, so lets go to case 2.

Case 2:
>Man is not attractive enough to get women
>Man has to get creative
>Man does something amusins. Perhaps learns an instrument, goes into a profitable career, starts a creative endeavor of other kind, etc.

Now there are two cases again

Case 2-1:
>Creative endeavor is popular
>Get bitches
>Put penis in vagoo

Again, this did not happen to Chris. So we must again go deeper

Case 2-2:
>Creative endeavor is a fucking piece of shit (sonichu)
>no women are attracted
>still no vagoo
>get fucking desperate
>nothing you do attracts vagoo
>You start becoming obsessed with women simply because you are now 30 and you have never seen one naked while you know back at your school there were 14 year old guys who got their dicks sucked by 5 girls
>start losing handle in reality
>become agressive
>this doesn't work
>No vagoo for your penis
>Realize your penis is useless, as it will never be inside a vagoo
>Become a vagoo

And that is where we are now. The fact that the motherfucker stresses so much that he wants to hang out with his "girl friends" just means that this is just a convoluted way of getting pussy, which won't work again and then we will see some real Elliot Rodgers shit.

>>9035049
You took way too much time to say "he's not autistic. He's just got a shitty attitude."

You might be autistic.

>>9035049

Chris chan is textbook autistic, the fact you deny it simply proves you don't have a clue what you're talking about.

>>9035019

It's not impossible but autism is best seen as a form of mental retardation, "fixing" it means fixing someone's brain, not an easy prospect.

>>9034518

Is there any way to do this with minimal effort? I really hate doing math and don't want to put any real effort into not being retarded.

Anyone with an IQ less than the person using the term.

Im sure there's some Darwinian explanation for why women devote more attention to their looks than men (makeup, clothes shopping, validation of looks etc.)

I would presume it has something to do with the makeup and expensive clothing being a norms for women (not sure why, somebody else can explain this), thus reflecting their poor self image and will to improve, which can often be validated by another mans attraction.

>Women need to be constantly validated and complimented on while men don't?
this is false. Men seek the attention of women, for the sake of attention, of believing to be worty by somebody else's eyes. Women do not need this.

>>9035105
Women had to attract men, not the other way around. Now that women are earning their own money, the men are trying to improve their looks more (Grooming, gym etc). Am I right about this?
