What type of engineering degree would be used to make a real life Iron-Man suit?
memegineering
Definitely not a one man job so probably a large variety of fields of expertise

Or you could just create J.A.R.V.I.S and have him ups your shit. But CS is gay
Why are rockets shaped like penises? Why not squares, rectangles or circles? Are penis shapes really more aerodynamically efficient?
Serious question.
>>7911747
Nature has had 3.5 million years to find the best aerodynamical object for stabbing shit, so yea, it is the best shape
>>7911747
>Are penis shapes really more aerodynamically efficient?
No, that's just a meme.
It was really all the fucking pig men at NASA that decided that that's the shape they will be going for. Because when you want to pierce the heavens then you got to have a giant dick, don't you.
They got that design from some NAZI scientists btw.! They wanted to tribute their neo pagan gods.
Fucking disgusting if you ask me
>>7911747
I think it has to with surface to content ratio. If I make it a cube shape you have more metal to carry per fuel which makes it inefficient.
Is there a recommended chemical to specifically destroy DNA?
Let's say I have an object I want to throw into the trash. But I touched said object and even ejaculated into it several times. I do not wish to leave genetic traces. With what chemical can I treat this object in order to make sure I cannot be identified anymore?
To prevent stupid questions: It's about my cum jug in which I collected my cum over months. I washed it out but I'm sure that's not enough.
>>7911728
just use bleach
>>7911728
chrome (VI) oxide and concentrated sulfuric acid. I bet this shit can destroy everything

Burn it?

And holy shit. Teaching STEM is worse because you'll be

I teach English to Japanese children and it's quite fun. No, I'm not a pedo.

Is teaching liberal arts really that comfy than STEM?
My english teacher used to scream all the time
Why do people consider physics to be such a great discipline when it's basically just pure math for people who cant do pure math? Is it because most of /sci/ is living this inadequacy and don't want to admit it to themselves?

What year did we discover what the sun actually was?
>>7911341
2009 when they released the new song about miasma that wasn't as good.

What is the sun?

nothing wrong with that question imo
What the hell am I looking at?
Why are these the videos I see before I actually find something remotely related to CERN? What kind of person floods the Internet with this stuff and who is promoting this trash?
>>7911021
>Why are these the videos I see before I actually find something remotely related to CERN?
Because /popsci/ people are more interested in the idea and potential of CERN rather than their accomplishments.
>What kind of person floods the Internet with this stuff and who is promoting this trash?
People who recognize that former statement to be true and want to make money off of it.
Seriously OP, think for a second before you shitpost.
>>7911050
Popsci people are more interested in loosely misinterpreting actual science rather than putting out conspiracy videos though. Making anti-science videos would be obviously counterproductive even to the popsci community.

Did you know that Springer means "knight", the chess piece, in German?
Why is Knight abbreviated N when it starts with a K?
Except we in Germany call it "Pferd" and not "Springer".
>>7910079
Because K for King I guess.
What's the difference between vectors and quarternions?
>>7910007
vectors are 3 dimensional, quaternions 3 but with 4 paramaters. Pretty simply actually if we represent a 3d vector as a rotation on x,y,z we get an euler orientation which basically sucks because you can get gimbal lock. Now make a 3d vector to point from a zero point to anywhere to describe an axis and use another variable for the amount to rotate around that axis.
>>7910007
Pretty great video by Numberphile:
https://www.youtube.com/watch?v=3BR8tK-LuB0
>>7910007
Vectors are a tuple of numbers, often used to represent position in an x/y/z kind of way; quaternions are an extension of complex numbers to represent rotations in three dimensions; they have four parameters and map to an axis/angle formulation of rotation. Two quaternion rotations can be combined simply by multiplying them together.
We all known that practice creates skill.
But isn't skill what *allows* practice?
Most people aren't able to long routines of practice simply because they don't get any better and its frustrating.
Talented people get a lot of progress in training so that it becomes exciting.
I think this applies to everything, including studies.
Suggesting people to study hard despite lack of progress is kind of ruining their life.

>Most people aren't able to long routines of practice simply because they don't get any better and its frustrating.
that isn't practice. practice involves self criticism and analysis of what went wrong and how to do it better. not just beating your face against something for some arbitrary amount of time.
>>7909950
>bawwww, studying is hard and I can never get better so why even try
How about you actually try different methods of studying? Do you honestly believe that people can only improve at what they were naturally talented at in the first place? People get better at things by staying determined even when their limitations come into play. Suck it up and stop pitying yourself just because life is hard.
>>7909950
it kind of goes both ways
practice definitely makes you better at a skill, but getting better gives you motivation to practice.
I play guitar and was terrible at it for a long time. I never wanted to practice because I couldn't translate the music in my head to the guitar and my phrasing was poor & choppy. I kept practicing and tried to learn new ways to express my ideas (learned new scales, rhythm, not rigidly following said scales, keys) while playing to a metronome and my playing improved...
