So I was playing around on SpaceEngine on my very mediocre PC and came across this view which I thought looked pretty cool so I screenshotted it (the image on the left). A day or so later I was watching SpaceEngine videos on YouTube and came across a video with the image on the right on it. I looked for the coordinates on the video but there was nothing there.
What are the chances of this? I couldn't believe it when I saw it, it's undeniably the same view, the chances of this are miniscule right? Am I the only one absolutely amazed by this?
>>7646981
That's pretty cool.
>>7646981
why is this a big deal? never used spaceengine
>>7647535
The universe in SpaceEngine is approximately the same size as the observable universe.

What's a book or something that will get me into quantum physics?
I don't have an outstanding experience in physics but i can wrap my head around some pretty complex stuff.
What do I need to know before getting into quantum physics?
I don't need it for anything other than having a better understanding of the universe.

There's a book by Susskind that I've been ogling a bit.
> http://www.amazon.ca/Quantum-Mechanics-Theoretical-Leonard-Susskind/dp/0465036678/ref=sr_1_1?s=books&ie=UTF8&qid=1447017481&sr=1-1&keywords=quantum+mechanics
Anyway, any of the hundreds of books with the title "Quantum Mechanics"--possibly preceded by "Introduction to"--will probably do. Bohm's book is worth taking a look at.
Thoughts on the aquatic ape hypothesis?

It'd be interesting an interesting discovery.
It's a form of feminism, but not backed up with as much evidence as typical feminist arguments.
Anyway, it's patently false. If we were ever aquatic, we'd have a lot more hair than our evolutionary cousins, not less. We'd be bulky and round instead of all gangly. We're built to dissipate heat, not keep it in.
The AAH has received little serious attention or acceptance from mainstream paleoanthropologists,[20][68][69][70] has been met with significant skepticism[70][71] and is not considered a strong scientific hypothesis.[20][5] The AAH does not appear to have passed the peer review process, and despite Morgan being praised by various scholars, none of her work has appeared in any academic journals of anthropology or related disciplines.[62] The AAH is thought by some anthropologists to be accepted readily by popular audiences, students and non-specialist scholars because of its...

lets face it world wars has been the best thing that has happend to the human race.the amount off technology that we got from it is staggering. just think of intense the race of getting the best technology was after the wars. but at this point we have flattend out and moving very slowly forward. we need a ww3 to get our speed of evolving back on track.
>>7646662
No, we would be even more technologically advanced and prosperous without the world wars. Prove me wrong.
>>7646666
I would if you didn’t have those decadent quads. :^_))

Tech advances during the wars... gg izy.
What are the odds that The Patriots won 19 of their last 25 coin tosses, /sci/?
http://boston.cbslocal.com/2015/11/06/toucher-rich-explore-how-the-patriots-are-winning-coin-flips-at-impossible-rate/
The same as the odds that they lose 6 of their coin tosses out of 25. I'm rusty on my babby probability, but here's a shot: There are 25C6 ways of losing 6 out of 25 coin tosses. There are 2^25 possible outcomes in 25 coin tosses. Hence, the following probability:
[math]\frac{\frac{25!}{6!19!}}{2^{25}}=\frac{177,110}{33554432}=0.00527[/math]
If you want to know the odds that the Patriots got at LEAST 19 out of 25, you need to add in the probability of getting 25/25, 24/25, 23/25, 22/25, 21/25, and 20/25. That gives you:
[math]245505/33554432=0.0073166[/math]
>>7646715
I'm not sure wtf is up with /sci/'s LaTeX, so here's an image of what I intended on showing you.
Here's a better question: what are the odds that *some* team wins 19/25 tosses? I bet it's better than even. And if you pick an arbitrary rolling window of 25 tosses, it's pretty much certain to happen eventually.
Your odds of winning the lottery are basically zero. But someone will win the lottery, and if not this week, then the next week or the one after. Same deal here, but on a smaller scale.
Why do people like rain?
Is it the sound of the water impacting the roof?
Is it the low lighting?
Is it the acknowledgement of not being able to go outside?
>>7646595
some kind of primal instinct that rewards you for being under shelter when the weather is bad. I don't think its too much more complicated than that
usually a sign of low test
>not being able to go outside
nigga walking around in the rain is great
I found some really old Maths textbooks in my local second-hand book shop recently. Some go back as far as the 1920s. They seem to explain Maths better to me than the newer textbooks, but they lack the colour of newer textbooks. Colour helps me remember stuff better.
So, what's better /sci/: Older or newer textbooks.
>>7646582
Generally older because they didn't fuck around with the explanations (plus they were shorter because of that) but if you need the fancy shit, you need the fancy shit.
/thread
>>7646582
old textbooks. They were good at explaining concepts and how to solve it. They didn't go off in a tangent of some stupid story you don't need to know. New textbooks put pretty pictures and useless explanations without explaining what the author is doing and why its solved this way.
>>7646582
Old text books. Not only old text books but old scientific movies explain shit in a very crystal clear manner.
Who here uses substances to increase mental performance?
I have antidepressants, 10mg/day generic prozac, that I gotta take or I just lie in bed hating myself all day. Although it feels like when I'm depressed I am more creative, better at playing piano, finding unique solutions etc. I also take caffeine and occasionally kratom which is pretty bomb for banging out a massive study session.
Try not being a faggot.

I take antidepressants, neuroleptics and drink alcohol.

I'm willing to spend whatever time it takes, and start right from the basics - the story is I've failed Math at a high school level twice, and I'm coming back to another local highschool to redo Math specifically
The thing is, I can never get interested in it in class because my base knowledge is so lacking, so most of the things they teach aren't intuitive to me
Pls help me succeed like Asian students /sci/
>>7646330
At this point I just need to get perfect algebra, trigonometry and coordinate geometry at high school level and maybe a bit more advanced
Any ideas where I can start?
If your basics are lacking study your basics.
>>7646339
What I'm saying is, it'd be nice if you could recommend a textbook that covers these basics in a grounds up way, or something along those lines.
I don't know much about Math, but what I do know is that the textbooks we're provided with are not optimal for learning Mathematics.

Why is algebraic topology so hard?

>>7646348
I don't, I just like the picture.
I grew up next to a slaughterhouse and was sometimes woken up by shrieks of pigs who were about to be killed. Can't we just gas animals (with helium) instead or is that technically impossible? Would be more animal-friendly and at least and also less distressing for the workers I guess.
>>7646240
Helium definitely not, it would be completely impractical. You probably could asphyxiate them with high percent nitrogen air mixtures, but that would also be extraordinarily expensive (just in terms of time required making vacuum sealed rooms), and it may affect the quality of the meat. Anything other than nitrogen would be too expensive to be considered.
Helium is expensive and it has more important uses than in animal slaughter, Mr. Sad Frog.

Is the placebo effect really as powerful as people claim it is? If so, can doctors prescribe you sugar pills without telling you?
pic unrelated
Sure. Its even more potent if you apply homeopathic principals. So one sugar molecule will literally cure all cancers. Big farma of course doesn't want you to know this secret.
>>7646196
>Is the placebo effect really as powerful as people claim it is?
Depends on how powerful "they" say it is. It's important to remember that just because you feel better doesn't mean you are better.
>If so, can doctors prescribe you sugar pills without telling you?
No because that's hilariously unethical.
Yes it is very powerful you can research that yourself. And no doctors can't legally give you a sugar pill. Doctors don't actually make the medication they get it from a supplier. So unless the doctor is ordering sugar pills (which looks shady) they are giving you exactly what they ordered from the supplier
