Are relationships for plebs /sci/? Do you date others interested in science and or math? What's the point besides sex otherwise?
sxience is sexy
>>8609433
You would be surprised how many people marry from within their field. A lot of PhDs and MDs get married to people that went through the same program as them.
I always thought that was interesting. I suspect that sociology plays a much bigger role in evolution than we have previously given it credit for. You either end with super shit parents or super awesome parents.
Pleb rss are for plebs.
Cold approach pick-up social circle game = being able to ACTUALLY find a smart researcher 10 who likes orgies.
That is if you're a true scientist at heart and focus on the experiments, results and what works, disregarding how much persistence it takes to get good.
Otherwise you're a ballless hypocrite.

Are economists as stupid and useless as some people say they are?
Its like applying math to literature
subjective, barely testable, barely science
micro-economics is fine
macroeconomics is for people who want to get government jobs or do academic research
Hi 4chan, amateur sci-fi writerfag here making a space novel about alien invasions and shit (I know, such originality). The question is: if aliens make a permanent base at one of Earth's Lagrange points, will they be able to land on different parts of planet as it rotates, or they'll be fixed above one specific place?
More detailed: let's consider Earth-Moon system and it Lagrange points. Let's say that an observer sits somewhere in America and stares at the sky directly at where, say, L4 should be located. The entire Earth-Moon system rotates but Lagrange points remain relatively stable within that system. However, Earth also rotates around its axis. So if that observer has nothing to do with his life (like me) and stares at L4 all day, will it eventually move away and disappear beyond the horizon? Or it'll stay fixed in one place in the sky forever?
To apply this in my novel: aliens are sending attack squads from a base at L4. Will they only be able to land, say, in US, or as the planet rotates, other countries will eventually be directly "below" L4?
>Aliens advanced enough to build a base in the middle of space
>Not advanced enough to fly around earth
>>8609095
I never said I'm a good writer. Also it's a bit more complicated, but I could go into the physics problem I want explained, or I could give you 7 pages of plot description.
L4 is certainly not on a geostationary orbit. Its exact movement relative to Earth surface is fairly complicated, but you could expect being above given longitude approximately every 25 hours. Eventually, everything on the strip between ~30th parallels N/S will have been flown over by your station (by eventually I mean, like, 15-20 years).
Is it time /sci/?

Sure, you first. Feel free to provide scientific articles from peer reviewed journals discussing it instead of politically charged youtube videos with bullshit "sources" like www.debunking911.com.
>>8607881
Right! Wouldn't it be nice to have some "scientific articles from peer reviewed journals"?
Why is that source bullshit. His scientific methods seem sound to me. Is it because you don't like his results?
This problem is what separates those who feign intelligence vs those who actually posses it.
The untrue believe the answer is 2/3.
But the truly intelligent realize the answer is 1/2.
1/10
And I'm only giving you the 1 because I replied.

It's a poorly phrased question.

https://en.wikipedia.org/wiki/Bertrand's_box_paradox
the only way it can be confusing is if you've never taken a probability course, or never seen a permutation.
the coin draws that fit the description are:
coin 1 from box 1
coin 2 from box 1
coin 1 from box 2
only the first two will result in the possibility of drawing a second gold coin, so the answer is 2/3

ITT: describe your worst teacher/professor you've ever had
Any teacher/professor who teaches because they are at a dead end and can only make bread by teaching, people like that usually ruin the whole learning experience and it's very common in pre university level courses. I often find that older female teachers do this shit.
Highschool math teacher. He didn't even care to teach, hated his job. Since I liked math he kinda helped me out, gave me some books and shit but to the rest of the class he was just the worst teacher.
when the class is a fluffly humanities requirement the teachers are usually worst of all

What does the future of photographing exoplanets look like?
Is JWST going to be good enough? I think there's more promise in telescopes at the moment while we are unable to physically travel beyond the solar system feasibly. Developing better "eyes" for the entirety of humanity seems pretty crucial to me. This photo is great, by the way. That there is an exoplanet. Here's an accompanying article: http://www.space.com/31497-exoplanets-direct-imaging-next-big-thing.html
>>8610892
Maybe we'll see a few more direct photographs of exoplanets in the future, but certainly not most of them. The problem is that you can't do it for every planet. The star needs to be close enough, the planet needs to be far enough from the star and it needs to be very large (>Jupiter). If that's not the case, you don't stand a chance.
So yeah, it's a nice benchmark to test the capabilities of your telescope, but probably not the best way to detect exoplanets. We might be able to make some spectroscopic analyses if we can indeed see them though.
>>8610912
How powerful can these telescopes theoretically be? Is it limitless to how advanced they can get?
I'm just imagining seeing an image like this in this quality.. but of an exoplanet. One day.. how far away do you think that'd be?
Seems to me like the JWST is specifically tailored for seeing older, red-shifted objects, and not specifically exoplanets, though it will probably be better at it than Hubble given the fact that it's from 1990.
Hi,
I have a question for hard-core chemistry nerds. I'm wondering about hydrocarbon's oxygen footprint while burning.
CH4 reacts with O2 producing co2, water and heat.
But in a fireplace with the damper closed, does any o2 fail to bond with carbon and instead go on to react with more hydrogen, thus leaving more carbon in the residual ash? Thus, releasing less co2?
I ask because they "sell" methane as "natural" gas, as if they're hiding something bad about its use. Certainly wood is the only renewable energy source, while methane is a drug that allows for a population of seven billion but is destined to run out and leave billions in shock. It may take a few decades...
>>8610322
Pretending to be interested in chemistry won't get you out of paying the carbon tax Ben and you will soon die by the hand of energy poverty like the rest of us. No wood for you!
Incomplete combustion, carbon monoxide is produced rather than more water.
>>8610322
they don't sell methane as natural gas, you faggot. natural gas isn't just methane, if it was they would sell it as methane and charge more for it. methane also burns very cleanly. when you see yellow in your flame that's due to carbon particulates, i.e. soot.

What gpa is is the absolute minimum that you would consider acceptable? Obviously ideal is a 4.0 but is anything less then like a 3.5 totally unacceptable and you're pretty much squandering your time?

If youre getting your foot in the door at a plant, firm or business, they could care less about your grade. Your likeability trumps all that on paper.
Hey /sci/, have a question for the medfags,
I know a girl who seems to have a syndrome but for the life of me I can't figure out which one it is.
Symptoms of it are that apparently it's harder for her to break her bones than it is for other people, but she twists her ankle and other joints very frequently. She has heterochromia, right eye is blue, left is green. She has Strabismus and she told me that even when wearing glasses or contacts she can't see well and her doctors said it could deteriorate until she goes blind, especially if she were to go through some difficult situations such as childbirth.
Other than the eyes she looks normal physically. Can anyone figure out what she's suffering from? I assumed the bones and the eyes thing are related.
>>8610201
Osteopetrosis (the opposite of osteporosis)
Literally all i did was google "opposite of fragile bones"
Symptoms can include blindness.
>>8610214
Wiki says it's more prevalent in a region in Russia, and she's Russian.
That's a pretty fucked disease, looks like she got a mild case
