red pill me on things thatt are even more mindblowing than vsauce/numberphile
I mean give me some intense logic based mind fuckery...
i want full frontal cerebral bore..
what is the coolest thing you know, that pertains to mathematics/logic?
>>8188014
Have you read The Extended Phenotype?
It's easy to read, as it's biology, but also it's a big bundle of novel concepts and insights.
Plus, you probably won't fully understand evolution until you read it.
>>8188014
Holy fuck kill yourself you cancerous retard.
>>8188028
Mind blown.
so today i was making some HMTD ( quantities dont really matter here ) and everything was fine until after some hours i forgot to cool down the mixture back to ~0C i went up to 40C so took the mixture back to an ice bath.when i came back after a few minutes the whole room was filled with a digusting smell and the mixture in the beaker was dark orange-black.i know that the problem was that the temperature was too high but whats strange to me is the runaway product it looked realy familiar to phenol formaldehyde but it was
squishy like a play-doh
note that its my first time posting on /sci/
(originaly from /pol/)

thats the only photo i took
anyone?
Hope you're hiding behind 7 layers of shitposts m8.

Is plasma donation worth it? What do they actually use blood plasma for? I've heard conflicting reports, some say that it's used to save lives, others say it all goes into cosmetic production. Any plasma donation stories anyone would like to share?
you usually get 20-40$ for it. America is worlds largest plasma producer because the poors donate as much as they can for the $$.
As for the plasma itself, its actually full of many useful things. Mostly various clotting factors and antibodies. Which companies purify out and turn around and sell to hospitals for a fuck load of money.
Ive never heard of it being used in cosmetics.

The CEO of rackspace highly recommended it. When he was starting his business, they needed extra cash so they donated blood.
But it turns out you could only donate blood once per week. This is not the case with plasma.
I have an arithmetic sequence 0,1,2,3...,2n
a1=0
Now the sum of the numbers at the even places is
n^2 if I'm not wrong, I used the standard arithmetic sequence sum formula where my first value is 1 and my last value is 2n-1 and the number of vlues is n.
Did I do this correctly ?
>>8187214
s(0) = 0
s(1) = 2
s(2) = 6
s(3) = 12
none are square
>>8187251
When you do S(3) my formula will calculate the first 3 values of the series ,that's what I meant
>>8187270
oh
so S(3) = s(0)+s(1)+s(2)+s(3)?
Bayesian is the way?
>>8187193
Answer cannot be A because if the answer were A then it would also be D which is a contradiction. With only B and C there is no way for it to be 60% this B is the correct answer
Ill-defined problem, the space you are trying to define a probablity on is non-measurable.
>>8187200
But how can be 50% chance to answer randomly right if there are 4 answers, and only b) is right?
1- There is 25% chance to answer randomly right a 4 question test
2- In this case there are 2 "correct" answers, so 50%
3- If 50% is correct, there is only 25% to answer this question right at random
4- Go to 1

What are the best absurd results of classic mathematics that you can use to red-pill these plebs with?
What a dumb cunt lol. Girls suck at math.
>>8187102
>absurd results
How about "distance does not exist because real numbers aren't real". Oh wait, that's an absurd result of Wildburgerism.
>>8187102
Lol, mathematics is nothing but a physical construct. It only manfiests itself in writing, neural firings in our brain (thoughts), and so on.
You can define it in any way you want. What matters is what kind of definition will lead to the best results, and allow us to construct the most predictive theories possible for the real world.
What's your favourite sciencey thing about the ocean?
There are more drops of water in the ocean than atoms in the universe
>>8186964
How much is a drop?
>>8186966
You can get them pretty cheap on ebay
Why so many people got assblasted because of pic related?
op i can't answer your question but chaalk me up for being assblasted
>>8186376
I dunno.
There are much weirder and spookyer patches.
I'm going to be interviewed by a flight academy in 10 hours, tell me random facts about planes and why they fly.
they have wings and spinny things and nice ladies who make you tea whenever you want
>>8185808
they go really fast
They're basically giant paper airplanes that create their own wind.
The whole worlds fucking backwards and it's terrifying. I just want everywhere to unite and do more science shit, facing real issues.
urgh u scientists are nothing but dumb idiots
>no art
>no justice
>no equality
gibs me dat money you fucking bigot, stop using it for your racist, deadly "research", and stop contaminating my food supply with GMOs
>>8185694
That genuinely sounds boring.
Real issues aren't strictly science-related.
>edge the edgehog
No. Kill niggers.
What does K^Aut(K/F) mean?
>>8185682
Aut is for autistic
K/F is for Kentucky Fried
>>8185719
What is this? /pol/..?
That's Aut for gold/time, K for Potassium and F for Fluorine. Galois was a master alchemist back in the day.
>>8185682
Aut(K) is the autism group of the field K.
let V be a finite dimensional C-vector space and denote by Sym(d,V) the d-fold symmetric tensors, ie Sym(d,V) is the dth-symmetric power of V.
This is in a natural way a GL(V) representation.
How do I show that it's irreducible?
>>8185669
if the matrix A has distinct EigValues x1,...,xn and v1,...,vn is a basis of V consisting of EigVectors of A, the the induced endomorphism on Sym(d,V) has EigVectors and values
[math]x_{i_1}, \hdots ,x_{i_d}[/math]
[math]v_{i_1}, \hdots,v_{i_d}[/math]
for all sequences
[math]i_1 \leq \hdots \leq i_d[/math]
>>8185731
and if W is a subrepresentation of Sym(d,V), then it must be spanned by a subset of these eigenvectors.
>>8185731
of course eigenvals are
[math]x_{i_1} \cdot ... \cdot x_{i_d}[/math]
eigenvectors
[math]v_{i_1} \cdot ... \cdot v_{i_d}[/math]
for all sequences
[math]i_1 \leq ... \leq i_d[/math]
Do any of you /sci/ mathematicians find pleasure in reading poetry?
only if it's depressive and nihilistic as fuck
if it's some love shitty bullshit i get bored very easily
>>8185524
I'm the exact opposite
>>8185514
yes of any kind. be it sexual, be it about love, be it about hate, or whatever.
What is /sci/ opinion on physicists again?
Engineers without the perverted sexual deviancy
GOAT tier, together with mathemagicians on the top of the pyramid.
>>8185491
It is the shitstain between engineering and mathematics. Neither is it aplied enough to make real world applications as in engineering, nor is it pure enough to reach the rigor as in mathematics. Hence physics is a fail.
How can I predict human nature (actions, thoughts, feelings, etc.) using mathematics?
I can, for example, calculate their average speed while they're running or even their instantaneous speed. However, I'm struggling to calculate their next move or what decision they've made at a particular instant in space and time.
Equations for their actions:
v=s/t , if human is running.
...
Equations for their thoughts and emotions at a particular instant in time:
...
Equations for what decisions they're going to make at a particular instant:
...
Etc.
Please, contribute.
graphs are used to model all kinds of things.
humans are a really complex to graph though. I doubt you'll make a complete one.
>>8185444
So it's an impossible project that I should not bother pursuing?
I predict with a 99.6% that you have autism
0.4% that you are just a clever shitposter
