How would you introduce modern technology into a midevial kingdom?

I just woke up from a dream where I was in this situation. The kingdom was a low fantasy Narnia without any magic. I ended up being killed just for talking about trains and jets to entertain a few nobles.

Now I'm wondering what would be the best way to bring a world like that at least to the 19th century. I would rather give them something besides weapons, so what would be the best thing to start with, that you could acutally do by yourself?

if you got less than 8 hours of sleep, 7 hours of sleep. Could you take 20 minute naps every hour that you're awake to make up for that missed hour? Would your body be better if you did? I learned in biology that missing a certain amount of sleep disrupts your natural biological processes

I wonder, what does /sci/ think of pic related? Over time, I've increasingly noticed that this board is full of high schoolers and people who genuinely believes the 300k starting meme and dismiss engineering immediately as cock sucking, without even thinking of how good it actually is as a degree for someone who wants a good paying job.

Anyway, as a maths undergrad, I'm most interested how highly this picture rates engineering. /biz/ gives me the impression that it's over saturated, and therefore your probability of being employed, even with the appropriate degree is very low (...and probably even lower with a slightly different degree, like I have no idea why anyone would hire me for an engineering job rather than an engineer, although I do understand the case for employing non-finance people for finance).

So /sci/, thoughts?

Why are some people so skeptical of science or hesitant to believe conclusions drawn through scientific methods?

I tried to explain relativity to a friend recently and she told me it was strange and she had a hard time accepting it, to be fair it can be a bit strange, but here's the thing she believes in all kinds of /x/ things like demons and shit.

It really struck me how she could easily accept those things but relativity was too "strange".

Why is it that you can present a person with scientific models of how the world works, with evidence, and they will be hesitant to accept it but you know tell them time is controlled by a time demon and they jump on it like "oh yea that makes sense!"

As much as I hate the cliche, reality often is stranger than fiction.
>>
>>7585555
People it more comforting that conscious forces are controlling things because they're easier to relate with.

Nothing is more terrifying than the realization that reality can't be reasoned with.

Also, checked
>>
>>7585571
Relativity and quantum mechanics are strange that's true. In many ways I guess they are more strange than a time demon.

Good point. We do try to humanize everything around us. We even like to think animals have emotions like ours.

Specialized in thermofluids in mechanical engineering, but I want to work on space hardware after my masters (Im in purdues aero astro masters program). People are just expecting me to continue on with my knowledge of thermofluids etc and dont really see my work as "astronaut experience." Have I made a grand mistake? I specialized in fluids because it was my only way into a top program like this, but now im competing with 22 year olds with flight experience whose dads were astronauts

Is Fortran a good first programming language? I'm transferring from a CC to a 4 year college next semester. One of the first courses I'll take is an intro programming for physics majors that uses Fortran. They also use C++ but that seems to come towards the end of the course.

Would it be good to start trying to learn Fortran now? Or pick a different language to get comfortable with before I have to take that class?

fortran? If they plan on wasting your time with shit like that, maybe don't even go there?
>>
>>7583425
Do you want to do numerical analysis? Go with fortran.

Do you want to do literally anything else? Don't go with fortran.
>>
Fortran is really awful, but also it's dead easy to do simple things, so it might be an okay introduction to programming. It's not as nit-picky as C++.

It'll introduce bad habits that you'll never get out of if you decide to learn high level programming languages later on in life. But it kind of depends on what you want out of it. If those are the only programming languages you ever intend to use, then you may as well start learning it.

I'm currently doing large molecular dynamics simulations in Ruby. The savings in debug and development time more than offset any performance losses from using a high level language. But if you're not going to use it in your class, maybe hold off on that.

If there were spaceships armed with weapons they'd be so far apart that they couldn't see each other, also because of the distance the last known location on radar or whatever they have would not be wholly reliable for a moving ship so you'd need scatter weapons or fleets of drones
