Why are STEM fags so obsessed with colonizing other planets, in particular Mars?

I mean, we never went back to the Moon since 1972. There was no point in going back once we realized that it really is just a giant white rock filled with dust. Is Mars any different? It's simply a bigger, and red, rock, filled with dust. I cannot see the appeal at all. On the other hand I can understand the appeal of landing on the moon, and I see it as a token of our development as a species that we managed to leave our own planet, walk on the surface of the moon and come back. But why bother with putting a man on Mars? The process is analogous to the landing on the Moon, we know that we can do it if we spend enough resources on it. Why are people so excited about doing it anyway? What would that prove?

My opinion is that there are so many things we need to fix in our home planet before we are finally "done" with Earth and ready to expand our territory to outer space. What are your thoughts on this, /sci/?

Mars has an atmosphere, even though it is extremely thin that is something very useful towards creating a sustainable human presence

There is also a lot of frozen water

If we created a thicker atmosphere on mars the temperature would rise, It could be very habitable within a century

I think it is important for Humans to lean to live off earth, In the long run we will have to spread throughout the Milky Way

Mars will be the first step towards that expansion, mistakes will be made and lessons learned that will serve invaluable in the next thousand years

Because, some days, the only way I can motivate myself to go to work is knowing that I'll make mad dosh, and that my work is bringing us one step closer to the time when Akari-chan and her friends can live happily in beautiful Neo-Venezia

Is there money in nuclear engineering?
Not talking about super rich, but like getting a job.

I'm a college dropout, making decent money as a software developer.
(Dropped out because i started development 4 years before i started college, i literally wasn't learning anything /g/ hadnt already taught me or researched myself, i now make an OK 45K )

Every day, more and more, i feel i fucked up and went into the wrong field.

Nuclear science is so much more interesting than what i'm currently doing.

I feel like were currently using a sledge hammer to drive finishing nails, in the way that current nuclear power-plants, are run.

Beta voltaics, and the science currently going on with duet-tritium + lasers really fucking interest me, to the point I'm considering going back to school, re-training, then eventually would like to go onboard with nasa designing power-plants for the next rover.

Literal country side powerplants are neat, but not really the field i want to go into, i want to join research teams and risk radiation poisoning to figure out the next big breakthrough, I DO NOT WANT TO END UP AS A FUCKING NURSE.

But would there be jobs waiting for me when i get out of school?
I feel like software development isnt pushing me anymore.
Is this a PHD kinda thing, or a masters kinda thing.

tl:dr how does one get into real nuclear science? Not xray techs and powerplant janitors.

is it "easy" to find a job that doesn't revolve around consumer plants or x-ray technicians?


Space is where it's at, so many variables to consider, would be a lot more challenging than what I currently do for a living.

>couple engineer friends were going to build a cubesat
yay time for me to learn more about space and physics
>they scrapped that idea, and started a "for profit" business instead

fucking a

I just want something of mine to be in space,, it's a serious goal i will eventually achieve, even if its after death and i'm being launched towards the sun. (sub space weather balloons just dont cut it for me)

What field of science/ engineering besides compsci is most likely to allow me to keep my glorious beard once I begin my career search?

Literally anything with maybe the exception of finance, which isn't really STEM. Grad students, professors, researchers, engineers, doctors, etc, all have beards.

Any sort of engineering will do. Because these people are, you'll most likely find a job as hustler and for this job your gay beard is just fine.

Why don't I ever see much talk about probability or statistics on here?

I know both of these areas are really employable. Are they just not sexy fields these days? I mean yeah, stat is applied and everyone who takes the intro course is unimpressed with how simple it is, but the upper levels of stat can be pretty damn interesting.

Dunno about anyone else, but stats is the one math course that's not required for my school's engineering program. Bizzarely.

Of course, being a fucking hopeless dweeb, I'll be taking it as an elective. But I wonder how many other STEM kiddies are.
>>
>>7809755
Basic stat is easy, just a bunch of tedious math (think plugging 40 different results into one formula level of tedious, that is if the prof teaches you to do things by hand). The hardest part is remembering the difference between the various flavors of X (X, X hat, X bar, etc.). That said, it's really useful because it teaches you keys to understanding/interpreting statistics (stuff like confidence intervals, the power of a given analysis technique, etc.).

The upper level stuff is more interesting. You dive into more sophisticated analyses, much more of the underlying theory, techniques to increase analytical power through blending of techniques, and the like. It's kind of an intro to the research researcher field (guys who do nothing but look over research and look for ways to improve research techniques).

I can't help but think that half of this text is language without content in a young Wittgensteinian sense. We created words and have deep discussions, but the words are actually meaningless.

>the observable universe is 92 billion light years in diameter
>within this there are (at least) 100 billion galaxies
>the entire universe potentially stretches out into infinity, with an infinite number of galaxies containing an infinite number of planets
>and yet, within this unimaginably enormous stretch of space, we are permanently bound to a couple rocks orbiting a tiny, unnoticeable and irrelevant star in a sparsely populated part of our tiny galaxy
>even if we go to other stars some day, it will only be decades after everyone currently living on planet Earth has died
>over 7,000,000,000 people will have died and been forgotten before we reach interstellar travel

What the fuck is the point of learning anything about the universe?
Sometimes I wish it was never created, an eternity of nothingness would have been better than 70 years of pointlessness followed by nothingness.
Fuck.

Besides Brian Greene's Fabric of the Cosmos, that Iraqi guy's 2 BBC series (one with some shit connected with nature) and that British guy that looks like a faggot's series, what other theoretical physics shows are there and you would recommend for me to watch? Also I'm staying away from Degrasse's Cosmos series and I already watched The Universe in full.

And so you should. Don't get me wrong, it's not THAT bad. It has some nice informations, but that Thegrass guy is terribly annoying.

Watch the original Comos series, it's majestic.

Didn't Morgan Freeman have a physics show or something?

>wavelength function gives,say, an electron a probability to be in a space range.

Does that mean that, even if we don't know, they do have a fixed location? Or is it wrong to assume they do have a position since they can also be considered a wave(wtf does that even mean)

How about you learn the math first before you look for an interpretation?

Let's say hypothetically we somehow managed to invent interstellar travel within the next decade, and then confirmed the location of extraterrestrial intelligence.
Then, when we got to their planet, excited to finally meet another intelligent species, we discover that they are primitive and are in what we'd call the bronze age.

Would you be disappointed?

No, it would be one of the most amazing scientific discoveries of all time. If you've been to one post-singularity world, you've been to all of them. It's the historically lost ages that really matter.

So I've got a circuit exam tomorrow, and the only kind of exercises I'm having trouble solving are RL or RC circuits with an impulse source.

Pic is an example, where Rb=10kohms, r_pi=1kohms,g_m=0.1S, Rs=Re=Rl=1kOhms and Vs=δ(t). I need to fine the Vc(t) function of the voltage across the capacitor without using the laplace domain, and I'm drawing a blank
