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.

How did you find out what's the best possible way to learn? Like, at first you struggle and don't know how to approach a topic. But now you've gotten to this point where you just execute and learn this stuff and even remember it without problems.

It seems like most things I learn are pretty fast forgotten. Any ideas?
>>
>>7729625
As corny as it may sound, practice makes perfect.

Take time out to do homework and study well before you have to. If you always do your homework at the last second you will be in a rush to complete not learn the material.

When you do your homework write it neatly and carefully so that you learn it well at first and can review it easily later on.

In Freshman year of college I just did homework and handed it in, never bothering to save or organize my notes. After my second semester sophomore year...

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.

>>
>>7729527
what are they in your uni lol?
Even numerical methods have associated proofs of convergence.
>>
>>7729527
I agree but I feel weird about it. I wish that everyone, not only math majors like myself, would approach mathematics through proof based problems instead of the usual 'solve it' approach. But then I think that no engineer, physicist, chemist, etc. will ever be even close to proving a new theorem by themselves so it is a bit pointless to teach them the logic of proofs.

What do you think about that?

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

You know what fucks me up? Infinity. Very idea of infinity is pretty crazy.

First up, real number infinity is pretty easy to grasp, because these numbers represent an definable countable object or what ever. Then you get the infinity of Pi and that shit. What ever, easy stuff.

What fucks me up is space, if you were to travel in one direction forever. You would ALWAYS find new "space". There is no edge, and if there was... would it make sense? But then how could it possibility exist infinity, and then how could just the idea of our universe exist without creation. I mean every particle, energy exists in a system, infinitely and always changing states or existing. But always existing. We exist because more matter exists than anti-matter. But what came first? The very fundamental particle we're all made up of, or the universe?

Doesn't even the idea of the string theory blow your mind? Because we can break up the quarks, then keep going, and going until we make up the fundamental particle. But what is that fundamental particle made up of? Just itself, but how does it exist just within itself that it made up everything but still it's here? Like how is this "string" particle able to make up fucking everything you see, but. It wasn't created by anything else?
>>
It blows your mind because it's doesn't fucking exist outside of math mental wankery.
>>
The "space" is infinite by definition. it means empty area, which is what you get by default. It's a pretty understandable concept. The matter that fills the space is finite and has a limit and ends somewhere.

It's not mindblowing at all.
>>
>>7729388
Just because something is defined as infinite doesn't justify it to be understandable to finite minds, aka us (humans).
