If in the moment you were a little sperm you had a conscience, and a god (just supposing) said to you:
-Your life is gonna be hard and shitty, you almost won't have pleasure. You'll work hard and be humiliated by your family, and everyone else.
So, in that moment you have a choice: never exist or life this fate. Would you prefer to suffer your entire life just to be alive (think well, you're lucky if you're alive) or without pleasure and respect from the others, life just don't worth living?

A nice post, but how is this related to /sci/?

Who sais suffering is bad? You can find value in nearly anything even suffering.
Bloody hedonists.

I don't think others boards are appropriate for this, and philosophy (I think it is) is also science. Just asking.

So? Most of the applications are analytical derivations from spatial DE models. There's no need for calculations.

Wow such difficult calculations...
I still don't get why there are semester long classes about about something that can be easily learned in a single day.

To develop creative problem solving and logic skills. There's also situations that are indeterminate etc. which require more creative methods to solve.
So it helps you to develop modelling skills on physical problems with baby math so you don't suck at modelling more complex physical phenomena later. It's also why circuits have an entire first year module at some universities. And why ChemEs have mass and energy balances classes.
How many more jobs will be replaced by software in the near future? Was discussing the point of software and what it's capable of with my girlfriend and offhandedly mentioned that jobs like hers could be automated in the near future and she got all offended.

All I can say is that more cerebral jobs aren't necessarily safer. It's important to realize that very often the skills that require the least conscious thought rely on those human abilities that have been evolving the longest.

Should I skip out on a math degree?
I want to get a BS in it but it seems like people wouldn't need it anymore these days because of it :^(
Also I read this article about IBM replacing radiologists from hospitals so that's one
Can someone recommend me textbooks for a good intro to topology and modern algebra?
All I've taken is linear algebra and set theory

Cool, how about algebra?
>>7713203
Cool, what about modern algebra?
I am a bit confused, since I passed my course in linear algebra few years from now.
If I can make a vector space over field R which has angles as elements, then angles are vectors.
So i know that angles can't be vector, but I see vector space (V, +, *), where set V contains some angles in Radian or whatever and I can see that these condition work.
1) (V,+) is a group
2) a*(u+v) = a*u + a*v
...
and so on by definition.
So what am I doing wrong?
Let's also make that V goes [0,2pi) to make unique neutral.
Yes. And?
but they shouldn't be, right? intuitively
Do you guys think someone who is "good" at writing fiction is as skilled and intelligent as someone who is good at high level math? To me it is laughable to even think is.

There are different types of intelligence. Being able to weave a convincing and well loved story is harder than math.
How fast is the earth moving relative to a stationary object?
A stationary object where?
>>7712647
Relative to the stationary objects on my desk, 0 km/s.
Relative to the sun, about 30 km/s.
The sun orbits the galaxy at about 200 km/s.
Relative to the invasion fleet from Tau Ceti, we're moving about 0.33c.
>>7712659
what if you chose an arbitrary co-ordinate near your desk, how fast would earth move away from that point
this is probably a bad question

Almost half (48.5%) of jihadis recruited in the Middle East and north Africa had a higher education of some sort, according to a 2007 analysis by Diego Gambetta that is cited in Immunising the Mind, a new paper published by the British Council; of these 44% had degrees in engineering. Among western-recruited jihadis that figure rose to 59%.
A study of terrorists in Tunisia – where an electrical engineer went on a murderous rampage in June – showed similar proportions. And a...

The ME doesn't have real STEM education. They publish articles on spiritualism and Allah controlling the motion in universe in their "physics" department's for fucks sake. Even the Nobel prize winning Afghan who reported this atrocious state studied at Western universities.
Anyone have the link to that news article so people know I'm not even making this up? Lemme look through my bookmarks quickly.

Maybe I'm retarded, but tend to think STEM individuals would realize how *irrational* the world is, after studying natural/physical sciences and maths. But hey, that's just me.
Talking out of my ass: the percentage is probably that high because I don't think the parts of the world like the Middle East and North Africa value much other than technical-skills or things applying to industry. Developing countries and places with less stable economic climates don't have much use for liberal-arts degrees. The only way a kid could go to college is to learn some sort of STEM field to apply to industry, I bet.
Also that last paragraph of your post gave me cancer.
How close can 2 atoms get?
When I touch a wall I know I'm not really "touching" the wall since the wall is made of atoms like me so the electrons on the outside of the wall's atoms repel the electrons on the outside of my atoms.
So its more like I'm touching a force field around the wall correct? And there's one around me?
Do we know the size of this field? Under normal circumstances how close can 2 atoms be? What about when they react chemically or nuclearly?
It depends upon how hard you push. The field strength varies as a function of distance. The strength of the field is equal in magnitude to the force you apply plug the value of that force into the equation for the strength of an electric field and solve for the radius. I recommend looking up the normal force and how it relates to particle physics
>Under normal circumstances how close can 2 atoms be
take a cup of water, that'll give you an idea since water is nearly incompressible
if you touched something hard enough you're hand will just be cold welded to that thing
Computational chemist here. We can apply methods that we know to be highly accurate around the equilibrium distance of the two atoms from comparison with experiment. Short of basis set issues (which are solvable), there is no reason to not trust those numbers. So yes, it can be calculated, and it turns out to be roughly exponential. The term we use is Pauli repulsion.
Most of the time, we don't really care about this part, though, it only needs to be repulsive and give a decent equilibrium distance. The other side of the potential is much more interesting.
Imagine a future where instead of creating something like Zumwalt, we create an equal tier spaceship.

Why America keeps spending so much money on military is a mystery to me. It is barely useful.
If I want to become a genetic engineer,do I need to go to medicine to get an MD or is biology ok?
I live in Europe

I don't know if biology is enough (it might require more than a degree), but at least in Spain there's a Biochemistry degree.

Which is more plausible, a flat earth or a young earth?
A flat young earth.
>>7710483
Young Earth, definitely. Flat Earth just doesn't work in terms of physics, and requires the existence of a massive global conspiracy to cover it up; all a Young Earth requires is for God to be a deliberately misleading dick.
>>7710483
A young earth if only because you can observe that the earth is round directly
When will the "its just a piece of paper" meme die?
People don't literally think they're just getting a piece of paper you silly autist.
>>7710068
you say that, but I have talked with people who literally view their degree as paper and nothing more.
>>7710062
People that view it as that are people that aren't going to use it.
I can call my brain a piece of flesh inside of my head, or I can view it as how I'm going to make my way in the world.
What it actually ends up being depends on what I do.
Does weed help studying?
5 minutes ago I couldn't study and now I can, so anecdotally the answer is yes
>>7709780
Study high, take the test high, get high scores.
(results may vary)
yeah it's the opposite for me. it's almost as if all drugs affect everyone differently (basically what every hippie has been saying since forever)
I'm jealous of the people who marijuana helps though. This population definitely exists, I'm just in the sect that can't smoke weed at all without living in a haze for a hours afterwards
