xDD nice bro I see what you did there
This thing triggered me pretty hard. You can't just suck up stars and shoot them out at shit.
Anyhow star wars science thread, what in star wars is scientifically plausible, what isn't?
>>7730168
>what in star wars is scientifically plausible
Nothing
Can all the manchildren leave /sci/ please.

hey /sci/ I have a question for all of you computer science majors out there. do you guys genuinely like computer science or are you just in the program for the job market?
I have to be honest, I don't like it at all. I'm afraid that I'm just so caught up in the STEM stigma that I'm going to bottle neck into a career that I honestly don't enjoy.
You're not gonna make it if you don't enjoy it desu
I like it. I did programming in high school, and went to study computer science in university to get my skills to the next level. I was not disappointed and I love the field. The job market is nice, it's what allowed me to pursue the activity I love, but it was a secondary consideration.
I love compsci but I hate web stuff. I'm seriously considering trying for a CE just to get farther away from things like WordPress.
Sup /sci/, need realitively simple crystals to grow, I've already tried the simple ones, but I'm looking for some more challenging ones I can do at home, I want to try out copper chloride, but no luck so far.
Get a high pressure high temperature chamber, run it for a few hundred years and you'll get some really impressive results.
I fucking hate crystals that humans can't make in a reasonable timeframe.
It's one of the few things you just can't fucking do.
I never knew people made crystals out of different shit as a hobby. I know nothing about this or how it works but it seems fun, can someone point me in the right direction?
>>7737416
It's fun because chemistry, but it's still a pain in the ass.
I'd recommend using Epsom salts (MgS), copper sulfate, or if you want copper chloride, i mixed copper sulfate and some plain salt together in hot water, DO NOT stick anything metal in it, it corrodes stuff really well.
if you want actual crystals of CuCl, then filter out the precipitate of the CuSO and NaCl, and then add water to it, dissolve it all, and then slowly evaporate the water over a few hours, should work
what's the cushiest job a person could get a degree in, where they have a ton of free time to do hobbies while still being on a lucrative salary?
be it engineering or science, applications or research, what tops it all in terms of income, schedule flexibility, and overall proficiency with science & math?
Imagination Engineer.
>>7736363
i said proficiency with math and science not dicks and manbutts.
I know what job you're talking about!
You're talking about being a millionaire who pays people to make himself more money.
thats a good dejree
Trivial Question to ponder:
When roughly were the majority of the world's current population born?
>>7735311
Between the 50's and 80's.
>>7735311
Is that a bionicle? Shit brings back so many memories
between now and then
Is math an invention or a discovery? Clearly our way of translating math is an invention.
Notice how these kinds of questions add nothing to mathematics?
This is why philosophy of mathematics is a waste of time.

Do you think its important to attend classes? I have social anxiety so i go to university only like 3 times a week. Havent seen much difference, since i can study everything with rate that is comfortobale for me, and you can find any information that you need in the internet.
I`m a computer science major, btw.
>>7739234
No. I didn't show up to my calc 3, linear algebra, or mechanics classes at all. Got As in all of them. I really prefer to just read the book and maybe watch some high quality lectures online.
>>7739238
Curious, where are you going to school that your lectures aren't quality enough? And why are you going there in the first place? I know that I obviously have to take initiative if I want to master these subjects but I don't see why I can't expect my professors to bring some quality to the table as well.
Does free will exist?
Pic unrelated
Please be more specific, your question is to ambiguous for me to answer
Depends on how you define free will.
A hard determinist would define it as "you have a choice without a cause", which is a no, because casualty is pretty much what underpins all of existence as we know it.
A soft determine would say that free a free act is one which doesn't rely on any causes outside of the one doing the action. From this definition, free will exists and casualty is preserved.
A libertarian perspective would say that you do and relies on the the braking of casualty and conservation of energy, and what that guy on Sixty Symbols refers to as "quantum physics woo".

If the universe somehow exactly returned to a prior state, would the history of the universe be cyclic?

http://www.scientificamerican.com/article/research-confirms-a-link-between-intelligence-and-life-expectancy/
"A more surprising discovery is that there is a strong link between mortality and IQ: higher intelligence means, on average, a longer life. This relationship has been extensively documented by Ian Deary and his colleagues at the University of Edinburgh using data from the Scottish Mental Surveys. In 1932, the Scottish government administered an IQ test to nearly all 11-year old children attending school on a single day. More than sixty years later, focusing on the city of Aberdeen, Deary and colleague Lawrence Whalley set out to identify who from the cohort was still alive, at age 76. The results were striking: a 15-point IQ advantage translated into a 21% greater chance of survival. For example, a person with an IQ of 115 was 21% more likely to be alive at age 76 than a person with an IQ of 100 (the average for the general population).
The link between IQ and mortality has now been replicated in upwards of 20 longitudinal studies from around the world, and has given rise to the field of cognitive epidemiology, which focuses on understanding the relationship between cognitive functioning and health. One major finding from this new field is that socioeconomic factors do not completely explain the IQ-mortality relationship. In one study, focusing on the Central Belt region of Scotland, researchers linked IQ scores for over 900 of the participants from the 1932 study to those participants’ responses on a national health survey conducted in the early 1970s. The researchers found that statistically controlling for economic class and a measure of “deprivation” reflecting unemployment, overcrowding, and other adverse living conditions accounted for only about 30% of the IQ-mortality correlation."
Well, /sci/, what do you think?
>>7738961
shocker, smarter people have better jobs, better living conditions, can afford medical care more often and take less physical risks.
Who would have thought.
>>7738979
Essentially this.
>>7738979
This, but the study isn't conclusive. On the otherhand officer workers sit on their ass all day and develop medical issues. Even with great medical care you can only live so long.
Are there any experts on physical attractiveness here?
-Is there a correlation between height and facial attractiveness? I know the girl on the picture, she is tiny yet has a cute face.
-Are brothers and sisters equally attractive? Or do you have to get "lucky" and get your parents best genes?
-Is there different ranges of physical attractiveness? What I mean by this is that someone is that you take 2 handsome man and put them next to each other, same body, they both have attractive faces, but one will always be considered more attractive than the other.
If you compare luke hemsworth to his brothers that will answer a few of your quesrions
>>7738748
For males it is more about how a female body moves more than physical looks at first.
>>7738748
>yet has a cute face
nice 1 m8
ok /sci. let's settle this once and for all. Is pure math or theoretical physics the master race of STEM?
i dont know
why not both?
You're a dumb faggot who by his 3rd year will realize he chose his major to impress anonymous virgin fags on an anime imageboard.
is it possible to deduce where it is?
It's like finding a baby in woman's vagina without her being fucked. Nope. It's 50/50

That's a 50/50
What version of Minesweeper is that?
If a sun made of ice collided with a sun made of lava, what would happen?
It would create an incredibly large number of exotic particles that would could use to warp space and travel faster than light
>>7738404
Lava is made of some relatively heavy elements that wouldn't be able to sustain fusion for long. It'd probably make a pretty big boom.
**THIS POST IS ONLY SUPPORTED ON GENTOO**
If everything is made of molecules and mostly empty space, and molecules are atoms combined with mostly empty space, and atoms are made of subatomic particles and mostly empty space, and subatomic particles are energy and not really solid, then can we say we have never found anything solid?
Do we have any pictures of atoms or subatomic particles that suggests they are actually solid, or can we only measure that they should be there?
E=mc^2 energy and matter are one in the same, which i think you're not understanding from your argument. Other than that, neutron stars are almost completely composed of neutrons (we think) and therefore "very solid" with no full atom structures to create empty space they're extremely dense.
You clearly have no idea what the word "solid" actually describes.
https://en.wikipedia.org/wiki/Solid

>https://en.wikipedia.org/wiki/Solid
So being solid is kind of an illusion then. Some atoms are resisting changing their formation, but there is nothing really lay-person-solid there?
