Sometimes images of unrelated things can be manipulated to look similar.

Within 50 years I want to be a computer.
Should I get a math degree or a compute science degree?
>>7729779
Get a shrink
This singularity crap is the alchemy of the 21st century.

So the mythology of it will be stripped away and it will eventually go on to inspire more rigorous studies which profoundly change our place in the universe?
Because that sounds pretty cool.
What's the science behind convincing propaganda which elicits strong emotional responses from people, to the extent of making them do stuff like kill people or even sacrifice themselves?
Also, where can I learn the science of making propaganda? I have a degree in video and graphic design, but this only means that I know how to use the software. I want to learn how to actually make the propaganda content.
You're probably best off asking /his/. There is the science of psychology, but it is difficult to get things more profound out of that than "racism feels good," "fear is powerful," and "belief warps perspectives." You need an applied study and that's what the propagandaists of history have done.

It's not a science. More of an art. like advertising and persuasion. I would look into marketing/ public Speaking/advertising techniques along with research into photography/design whcih should teach you how humans react to visual stimulus.
Also psychology in general would be smart to research.
psychoanalysis contributed directly to the creation of modern advertising

The most powerful nuke ever made had a blast yield of 50 megatons.
What if you made a nuke with a 1000 megaton blast yield?
I need to know for a video game I'm making.
I though the experts on /sci/ could calculate just how powerful this shit would be.
Discuss
>>7729678
Anything with a yeld of more than 100 megatons will produce a fireball that will be bigger than the atmosphere, dispersing most of its power in the outer space.
I don't know, but here's a proportional view of the blast size.
Beyond 50 megatons we don't have any data, so we would have to speculate. I would imagine a blast radius estimate would come from an inverse square or inverse cube calculation, in which case you would get 2-5 times the blast radius of tsar bomba.
Here's a cute interactive calculator:

I'm happy this is wrong so we don't have to worry about 50 km nuclear fireballs.
Is there a ratio to determine if your shoulders are wider than average? I know that there's the golden ratio, 1.618 , but is it indicative of wide shoulders, or of "scientifically-approved" beauty?
Does pic related look like he has wide shoulders? He's 198 cm.
>>7729533
No, there is no scientific aspect to beauty. Our tastes are 100% social and cultural influence.
The guy in the pic has a pretty normal build. I myself look just like him
>sage for /fit/ faggotry
>>7729568
No, but there is the golden ratio. There must also be an average ratio of shoulders vs. something which would then determine whether a person has wide shoulders or not.
>>7729533
can anyone, please?

Reposting a saved thumbnail should result in an immediate ban.
>>7729487
I'm sorry
>>7729487
Wait? That doesn't make sense... Everyone is allowed to save pics from the internet, and re-uploud them.. I will not make a pic for every post i make!
Hey. How do you think, what is the optimal age for starting to learn children chess? And when its too late to start learning if you want to achievie aprox 2000 elo?
>>7729471
optimal age is as soon as they show real interest
generally considered that they must have 3 to 5 years before puberty if you want them to achieve master level skills without an inborn natural talent
>>7729471
lower age the better
>play video games as toddler
vidya will be intuitive
>play piano as todler
piano is intuitive
possible at later age, but I remember as a kid being obsessed more easily. Today I have a more difficult time finding interest in things that i'm not already good at
the best age to start is an IQ > 190 if u want them to ever achieve any success
>mfw today I learned what a Banach Space is

Can equations such as
x^x^x^x^x = 2
or x↑↑5 = 2 if you prefer
be solved anylitically
*analytically
my bad.
>>7729321
no
you can't even solve x^x=2 without lambert's function
>>7729321

That's a single arrow dumbass
What happens to the Hubble sphere and observable Universe under the standard lambda-CDM model?
Does the Hubble sphere grow indefinitely? I am thinking of ordinary distance, not co-moving distance which is known to reach its limit of appr. 62 billion light years as time goes to infinity.
Or let me rephrase it this way: assuming that today comoving distance equals proper distance, is there a limit for the size of the observable Universe in units of today's proper distance?
>>7728893
No. The Hubble sphere saturates in comoving coordinates but not in proper units.
>>7728981
So, it means that the observable Universe will eventually become infinitely large and, threoretically, two particles at infinte distance could interact?
Which universities for Computer Science still use non-meme texts like SICP? (MIT switched to Python but that's because the electrical engineers need it interface with the libraries control their robots)
All the universities that I knew of switched to Python. Bump for interest.
Can nobody think of a university that still teaches Scheme?
>>7728722
eh. should probably be learning clojure instead anyway.
is the sense of smell really a quantum phenomenon?

I would do terrible things to those toes

its just goddamn feet, id rather see some nice feminine hands tbqh
fucking feet
hate'em, you foot freaks should stop existing
Recommend introductory combinatorics textbook for self-study (with full or partial solutions for odd-numbered exercises at least).
One of the aims (not general) is a better understanding of setting up unconditional probability problems.
It's a big book. But it is like Steward for Combinatorics (perfect for beginners).
>>7727557
>It's a big book
for you
>>7727557
Thanks, man, but I have read Epp's Discrete Math. Now I'm reading Koh/Chen's "Principles and Techniques in Combinatorics" but it have a disorderly problem set without dividing on (sub)chapters and doesn't deal with some topics like Polya counting, etc.
why, in humans, are large butts and Lordosis Behaviour so arousing when these features aren't observed in other primates?
What are you talking about if anything it's less pronounced
>>7727097
chimps and gorillas don't do that though
fuck that baboon thing.
>>7727086
Excessive lordosis isn't appealing though.
Why are cat ears attractive? Why do people want to fuck greys, if they're in the right mood? Humans will screw anything that fits a certain set of criteria. Humans will sexualize inanimate objects that have no discernible relation to the human form. Though those might act as fetishes.
It's a multifaceted deal.
Why not artificially breed human embryos and genetically modify them to have progeria and study them to cure aging? If you breed a human species that lives the span of a fruit fly, I'd say you could cure aging fairly fast. Thoughts?
>>7725473
Because it is unethical. However, you could try moving to China and doing it, or building a secret lab in outer space.
>>7725473
too expensive. Babies take too long to mature.
>>7725473
Do it in rats first.
