How would you go about calculating the rough cognitive collective of a society?
Something like the total available processing power combined with the meritocracy of the society to select better intelligent minds for higher positions. Also combined with how scientifc the society basically is.
Something like:
Average g
How well society sorts average g to have more power
The general framework g acts in, such as using scientific methods and how rigorous are those methods.
Basically some measure of total effective brainpower for a society.

Did you remember to divide out sociopaths?
Let's not forget that even a rock can drastically reduce the intelligence of a single person.
>>8016516
We should just have every politician in office take an IQ test and then we get the average IQ of the people in charge.
If we want to get creative we could 'weigh' the IQs. Have the president's IQ count as if he was 100 people so that if he has a low or high IQ, it impacts more the overall sum. Mayors should count only as 1 person, and people like senators like 5, etc.
Then we do the same for every first world country and then we could know which country is the smartest country.
Then we could compare that ranking to the countries with least crime, highest GDP, etc. and see if having smarter people at the top is actually visibly good.
But of course, this will never happen because of Senator Whitey McWhitey gets an IQ of 125 and Obama gets an IQ of 124 then immediately the study will get called racist, sexist and homophobic.

That would only give us the organizational intelligence of a civilization, not the collective emergent potential of an entire population. Nice idea on measuring the effectiveness or authority though.
Ok /sci/ there is this one fucking kid I know who's ignorant as fuck and this is what he said to me today: "We're talking about things you don't understand, like English. What good is a scientist that can't convey his viewpoint?". Also inb4 high school drama... we both take APs and we're pretty intelligent but what he is basically trying to say is that since my english skills aren't great, I won't write good science papers. I am not good at english and I am not bad but am I the only one who thinks he's fucking retarded for mentioning my skill in english when I want to go into physics and mathematics? I mean I have alright grammar, which I will be improving but writing a super thoughtful essay on a paper talking about quantum mechanics doesn't matter as the only fucking people who would understand it are fellow physicists. He's definitely trying to start shit but I wanted all of your opinions on the importance of good writing in a scientific field such as physics. Also this kid is hypocritical because he wants/wanted to do engineering yet he doesn't understand basic calculus, which is required for engineering unlike english not being required for physics (it's required obviously but it's not a huge fucking deal).
TLDR: Opinions on strength of english skills in science relative to a field such as physics? Do I need to be like shakespeare?
If you suck then git gud

I just don't really like literature and writing as much as someone going into a social studies or language. I don't suck he just knows that's the one thing I'm not so great at.

Both if you should kill Yourselves.
Let's talk about transhumanism.
I want to be a cyborg ninja with super fast and strong robot limbs with laser guns attached to them and nanomachines in my brain that make me super smart and give me telepathic powers and immortality with my consciousness having redundant backups.
I also want a jet pack attachment.
how about you?
Oh yeah and the jetpack is here.

What is the possibility of someone with Autism/Asperger syndrome having a high IQ or just being highly intelligent (implying that they haven't taken an IQ test yet)?
It's actually just a stereotype that people with autism or aspergers are intelligent. Most of them are below average intelligence but when they actually are intelligent they are VERY intelligent.
>>8016235
Having a brain that makes it exceptionally easy to identify types of rocks won't help you very much if you want to interact with society in a nonparasitic fashion.
>>8016671
Can confirm, I have aspergers and I'm a fucking dumbass.
tau or pi? and why?
also math discussion general thread I guess
Pi. Tau refers to Pi.
How come this is more fundamental than Newton's laws of motion? Some textbooks goes as far as claim that particles "smell" their way beforehand and you need quantum physics to explain it.
But when I solve problems, I usually get (with a constraint [math]g(x,y,z)=0[/math]):
[math]- \nabla U -m \ddot \bar{r}+\lamda (t) \nabla g=\bar{0}[/math]
But [math]\nabla g[/math] is just a normal vector to the path the particle takes, so [math] \lamda (t) \nabla g[/math] is a force that is normal to the path, which makes sense as you need some force to keep the particle on the path. And clearly [math]- \nabla U [/math] is the conservative force. I don't see how this has more than Newton's laws of motion. Yes, it is easy to solve the variation problem with more generalized coordinates but that's just change of coordinates.
[math]- \nabla U -m \frac{d^2}{dt^2} \bar{r}+\lambda (t) \nabla g=\bar{0}[/math]
>>8016099
Because it holds in so much more general situations.
i.e. Works for this [math] S = \int {\operatorname{dt} \left[ {\frac{1}{2}m{{\dot x}^2} - V\left( x \right)} \right]} [/math]
And also works for this, [math]S = - {T_{Dp}}\int {{d^{p + 1}}\sigma } {e^{ - {\Phi _0}}}\sqrt { - \det \left( {{g_{\alpha \beta }} + {B_{\alpha \beta }} + k{F_{\alpha \beta }} + k{b_{\alpha \beta }}} \right)} + {\mu _p}\int {{{\left( {C \wedge {e^{B + kF}}} \right)}_{p + 1}}} [/math]
>>8016491
Even if it works, can it still be fundamental?
is there a mathematical explanation for this?
explain the prob of 12 times zero in series part?
1/81 = (1/9)^2
= (0.111...)^2
= something about infinite sums

thats just a trashy calculation for assumption of random distribution of numbers in a run. 10^(-12) * 100%
why is graph theory such a raging meme?
What does this even mean? Are you asking why graph theory is becoming increasingly popular in the past 50 years?
>>8017136
No, OP is asking why it's such a raging meme.
Try reading next time buddy.
Because you are still not developed enough to understand its applications.
I got part A and B, but I don't understand part C. I have the solution but I don't understand it.
For (c), suppose that e_1 is in W. Then, there would exist N such that
[math] e_1=\sum_{k=1}^N c_k\sigma_k [/math]
But you showed in (b) that the e_n(k) were an orthonormal basis, so you start taking <·|e_N> on the relation and going down you will discover that all the c_k are 0. This is a contradicition so [math] e_1 \notin W [/math]
For (b), notice that e_n is NOT in W for each n, because <e_n|\sigma_n>≠0. Therefore, W perp is 0. Then you are done

fuck off, this is a great exercise for a first course in proof based linear algebra, so for mathematics sophomores
My current life-plan is to go into computer science and neuroscience once I graduate from physics: I'll either somehow do a master's in both or jump straight into a PhD. But to do this I'll need to learn a lot..
I have a vague notion of where to start for CS
>Logic Manual
>Intro to Boolean Algebra & applications
>Code
>GEB
>Computability
>The Principles of Mathematics
>Intro to algorithms
>Principia Mathematica
>On Formally Undecidable Propositions of Principia Mathematica and Related Systems
(suggestions would be nice)
But as for neuroscience I'm not so sure. I'll have to start by learning organic chemistry for sure, but I don't know how much biology I'll need to know to have a holistic idea of the brain. Can anyone direct me here?
Thanks much.

Howdy, /sci/, what's your favorite insect defense mechanism or just oddball insect behavior? I'll start:

The motherfucking bombardier beetle, literally roasts its enemies alive. It ejects a mixture of two chemicals from its abdomen which, on contact, vaporize and rapidly heat up while traveling towards its targets, literally cooking them alive.

Anyone here can explain to me the problem of observation of quantum particles and how the simple observation can change reality?
I think that people is misunderstanding the whole point and adhering to it every kind of mystic beliefs. I love science but the quantum physics world is beyond my studies, so I'm reading on it but I can't figure the experiment point on my own.
>>8015831
>Anyone here can explain to me the problem of observation of quantum particles and how the simple observation can change reality?
It doesn't.

so the quantums have multiple "faces"?
Why all the importance of the discovery then? They make it sound like is much more than that
Say, what should one pick his engineering major based on? I'm doing an introductory year where we study courses representing multiple engineering disciplines, and it's safe to say my favorites have all been related or somewhat related to MechE, Statics, Dynamics, Descriptive Geometry and multiple topics of Physics.
But before doing this year I've thought I would study Electrical, based off my interest in it's real world applications. I would've liked to learn programming and I'm a huge fan of technology.
Tl;dr: should one choose his discipline based on how enjoyable one finds the courses or simply one that compliments his real world interests?
I know major questions belong to /adv/ but this is a more specific question which I thought it belonged here more.

I'm an electrical, but pick the one that interests you. I know lots of younger engineers who are ME and wish they did EE, CE.... And vice versa. You can always change horses if you feel your interest waning.

Do you need a licence to operate a home lab?
I mean, say you synthesise a common drug. Can you legally sell it?
If not, what steps need to be taken to legitimise the lab?
Is there some kind of mandated purity test, or a requirement of a doctorate to work at such a task?
>>8015716
this is way to vague
if you dont have any restricted chemicals, and dont synthesize any restricted chemicals, then you can do whatever you want
if you do have something thats restricted, you will need some form of paperwork to have it / make it.
If its a food or drug, it needs to be approved by your countries department that deals with that sort of thing if you want to sell it, if it is on their list.
>>8015716
If it's a meth lab, then no.
Only if you live in the United States of Freedom.
