Hi, two questions.
1. I have a big test that I'm somewhat nervous for, what music is best to listen to before a test, and what music should I definitely not listen to? Classical? "Pump-up" music? Piano? Ambient? Chaotic avant-garde music?
2. What can I eat that will keep me awake, focused, and energized for a long test?
>>8134189
1. Look up piano playlists on Spotify
2. Bananas
>>8134191
What about piano music that I already really enjoy, or should it be something that won't get stuck in my head?
>>8134189
I'm pretty sure results vary wildly for different people but this this what I do;
1. nothing at all. I have commute for 1.5 hours on public transport to get to my uni, and I usually read. before big tests I just sit and do nothing but clear my mind and then organize ideas and concepts for the test.
2. fresh fruit half an hour before.
Every time I point out a problem with Musk's Mars plans I just get "reuseable rockets bro!" thrown at me. There is no point in arguing with these imbeciles, they think reuseable rockets will solve every problem in space travel ever. Musk hasn't even reused a rocket yet FFS.
The whole thing has pretty much become pied piper-tier now. Legions of neckbeards unhappy with their mundane lives believing that this one man will get them an exciting life on another planet. It's all faith, BFR, MCT are all dreams. No maths to back any of it up, cancellation upon cancellation of even the Falcon Heavy. If I ask how is it going to make it 225,000,000 km? I get the reply "it will be really big!" and if I ask how is it going to get there for less than $100 billion? I get the reply "It will be resueable!". That's it, that's the entirety of SpaceX's plan to get to Mars. May as well wait for Jesus to take you there.
what gives you the credit to point out the problems with Musk's Mars plans?
Falcon heavy was not canceled or delayed
They chose not to work on it because there was no market demand for it
They haven't reused rockets yet because they are limited on launch rates and want to study the landed stages/make sure theres no damage.
Possibly they didn't have extra stage 2's at the time either.

In/On my eyes, I have 3 types of "things" floating around.
The 1st type seems to be on the surface of my eye. Those look like fibers, dots, and a few other shapes. They look like super out of focus stuff and will shift, drift, change type, and disappear when blinking. Sometimes there aren't any and sometimes there's tons.
The 2nd type seem to be standard, "floaters." They are just dark shapes that I rarely notice. They don't move very fast but almost always move "down" relative to gravity. I started noticing these shortly after being electrically shocked into unconsciousness.
The 3rd type seems to be something akin to moving "pixels". I can only see them well when looking at a bright solid color, like a white wall or azure sky. These are best seen in sunlight. They encompass my entire vision, as though my vision is completely made up of only these moving things. They move like whirligig beetles on the surface of water. Fast and erratic. They speed up, slow down, squiggle their path, do loops, etc. They don't show up as a solid object. More like movement traces. The best way to describe them is by looking at the later part of this image of whirligig beetles, when they move faster, and imagining them being invisible where you can only see their trails through the water. I've been seeing these since I was a small child. Another very good example is microbe movement like in this video: https://www.youtube.com/watch?v=EKMmmoymW8g
My question is, what the hell is the 3rd type?
>>8133785
Yeah I have something similar, like a pink static constantly fills my vision and is worst at night.
I've learned to ignore it. Thats about all you can do.
>>8133785
I forgot one more thing with the 3rd type. When I sneeze of cough really hard, the "stars" I sometimes see a second after that trace out the same squiggly patterns. It is as though, some of those things get bright for just a very brief moment.
>>8133793
Pink. That is neat. Mine are more like chromatic aberration you see on a super close up macro image, but there's no source, just a squiggly point of chromatic aberration. So they tend to have many colors.
Hey /sci/
Give me the science behind falling in love and love at first sight.
It is something genetic or does certain physical features trigger something in the brain?
I've maybe had love at first sight 2 times in my life. I've seen and met a lot of girls but only 2 really made my instinct go off, as, that girl I want to start a family with. I have now fallen in love again, with a girl I cannot reach, whom is very far away. It hurts to think about it, that I can't protect and care for here. So I try not to think about it, or to look at her pictures, to avoid those feels.
Also, why is love at first sight often only at one person, while the other might not be attracted in you. If you're body / brain sees a certain girl as perfect for a bond then how come the other one does not necessarily see that in you?
>>8133588
Love isn't real. It's merely a meme, created to manipulate you into becoming a cuck.
>>8133588
Edgy fedorian reply here, but its chemicals, man.
You like big titty lady cause shell have plenty milk for a kid
You like wide hips lady cause shell give birth easier
A woman wants big dicks for satisfaction and the guarantee of fertilization, and good genes to pass on to offspring.
Even if kids aint what you aim to have, remember: you are programmed to do two things. Survive and multiply

Then how come the grills i like are flat chested
It's a bit of a sick joke isn't it? All kinds of unimaginable stuff out there waiting to be explored and we will never be able to reach it. And we're just at the very beginning of knowing we will never be able to explore. It will eat away at humanity, little by little, millennia will pass and humans will get no closer than we are today.
I can't deal with it.
>>8133324
>All kinds of unimaginable stuff out there waiting to be explored and we will never be able to reach it.
'unimaginable stuff' is a weird way to describe a vagina, but your conclusion is valid if you applied to yourself.

I am interested in frequency resonance after experimenting with a sound system and a low frequency oscillator on a sine wave.
Certain frequencies caused parts of the house to and other frequencies caused other parts to resonate.
I am really interested in this concept. Can things (buildings, cells, animals) be resonated to destructively? What effect does resonation have on the human body? How far can frequency resonation travel through sound waves? What sort of frequency resonation occurs in space, magnetic? What’s the relationship between magnets and sound resonance?
The most fun part of experimenting with the resonation in my house was hearing the first buzz of something rattling, and then finding I could slowly turn the oscillator to a lower frequency and it would continuously resonate at a frequency where it did not before, if I was subtle and careful with the change. Is there name for this?
>>8133300
careful researching this publicly, I've been called esoteric for reading books on this topics but to be frank it can indeed get pretty wild...
I throw you a few terms which could be interesting to look up, cymatics, resonant frequencies, sound levitation and if you dont play an instrument, music theory.
You should take an acoustics or vibration class then.
>> can buildings, cells, animals be resonated to destruction
For buildings see earthquake.
For animals and cells there is this handy lab device known as a sonicator. It applies intense sounds to destroy cell walls so you can get stuff inside out.

Shit science question time!
Okay here's the deal: about 4-5 minutes before feeling a very compelling desire to take a shit I get this hyper focus. Suddenly reading some new wikipedia article, learning something new, studying on something usually boring and mundane becomes extremely interesting to me.
After taking the said shit, the focus is flushed down the toilet.
Is this phenomenon widespread? Does everyone feel like this? What's the science behind this?
>gotta go take a shit now
>>8133143
I have never heard of something so bizarre.
Maybe when you read interesting things you associate that feeling with taking a shit since you tend to read interesting stuff on the toilet?
>>8133143
have you thought that... being hyper focused and starting to learn something new makes you want to take a dump?
I think your shit may be giving you an anal orgasm, and you're all fucked up on oxytocin afterward.
How many papers are people expected to publish a year?
I noticed a PhD at researchgate, that in 2016 has 10 papers published, (almost 2 per month) and there´s still 6 months left in the year, those papers are mostly about the same topic but from another perse.
I as a graduate student i have only 1 paper that has a lot of effort and quality put into it. I started en february, finished in April (sent to review), and tomorrow june 10 will know if it was accepted, and im barely starting to think about my next paper at this rate i would be able to publish 2-3 papers per year assuming i "got gud" at this i migh be able to make up to 4-5 papers per year but still i have the question
So again, i ask
How many papers should a undergraduate engineering student try to publish before graduating?
How many papers should a masters student in engineering try to publish before graduating?
How many papers should a PhD in engineering try to publish before graduating?
>>8133042

Dunno if this is the proper place but let's try.
I am a electrical engineering student and i've been looking for a new calculator, since i'm starting the specifics classes i will be able to use a graphical calculator, so my question is:
which one should i buy a HP 50g or the HP prime.
i thought in buy a texas instruments calc, buy in my country they don't have support for the buyers
>>8132233
You still use a calculator?
>>8132239
i know i can use a smartphone, but i doubt the teacher will let me use it on a test
>>8132233
>electrical engineering student
>wanting anything but MATLAB and basic scientific calc
from one to another: that's just dumb
I am so fucking confused so I come to you, sci.
How is three phase power distributed and where does the neutral come from? I guess I am stupid because I have already read some Wikipedia articles and watched some videos but still can't wrap my head around it.
My two confusions are the neutral wire and three phase transmission. So I see three wires on the pole and these three wires go to the transformer and out comes four wires? Where does the fourth wire come from? Is it connected as input to the transformer or formed just on the secondary side? Is that netural white ground? If so is it just a wire going to the ground like residential grounds where you just bury a metal rod?
>>8132140
>How is three phase power distributed and where does the neutral come from?
The neutral is a center tap on the transformer secondary.
>Browse to Wikipedia
>see picture with four wires on pole
>read text that clearly describes "one wire for neutral, others for A, B and C phases"
>conclude that OP is an idiot.
>>8132140
you don't need a neutral at all times.
look up floating neutral you faggot

the "ae" form near the middle is nearly identical to a band logo design for the electronic music group "Autechre", that they used more regularly about 15 years ago.
In fact it's so similar that I want more context on the image, and I wonder if Autechre or their logo designer was aware of this (if it preceded the late 90s). image looks like Star Trek: TNG, like Shut Up Wesley's homework or something.
Can one of you gents or ladies explain to me what this 3 lined stretch of this organic structure represents?
Two triple bonded carbons.
Go back to OChem day 1
>>8129912
it's a triple bond between two carbons, you brainlet
from left to right:
CH3 - CH2 - CH = CH - CH2 - C ≡ CH

Hello, /sci/, no dark matter guy here again.
This is why I don't worry about the big bang and why you shouldn't either.
(Unless I'm wrong of course)
https://www.youtube.com/watch?v=w19vXcOoMlU
Yeah, no. Misinformed as always.
Current cosmology does not include any mention of a primordial singularity. That is an outdated idea. You're debating a strawman.
As to why the universe kept expanding the the very early universe that can be solved by looking at it today, it's flat. If it's flat today it was flat at all times under standard cosmology so at all times it was able to expand forever and overcome it's gravity. Because it was flat there is no global curvature and because there is no global curvature it never forms a black hole. So your whole premise is wrong.
Dark energy is the late time effect in cosmology. It did not have an effect in the very early universe. Unless you're proposing some radial equation of state but then I request a demonstration it works within current constraints.
You cannot do cosmology in words. Learn some real cosmology and start with the Friedmann equations.
>>8128263
>radical* equation of state
Dark Matter obviously does not exist, it's just a little thing to patch up faulty formulas.
Do genetics really determine how intelligent you are? Or just lay the foundation for your potential? Emphasis on potential here.
You aren't born a bodybuilder too after all. You work to become one. It's just that genetically some people are inclined to make greater progress than others even when they train equally as much.
your mom really determines everything

i live in san diego and we are infested with military redneck subhumans; to be fair some are ghetto brown/black urban types.
inbreds who join the military are subhumans from the shit ass middle/southern states and are sub-walmart level in employ skills
many of them marry the first hooker they have sex with overseas while on deployment
so in sd you see lots of kids with hick dad and hooker mother
for some reason these kids tend to be smart
these are the combos i have seen:
dad redneck from arkansas - mom korean hooker
kids go to harvard princeton mit
dad redneck from kentucky - mom thai hooker
daughter goes to ucirvine michigan
i always wondered if knowing their mom was a hooker made them work harder to get away form it all
everyone knows what they are and it is kind of funny to have a friend with a hooker mother

Why is PopSci so popular?
Why is pop music so popular?
>>8133282
I mean, the alternative is for society to think you're stupid nerd for doing actual science.
A little popsci is an acceptable alternative.
>>8133282
> Why is PopSci so popular?
It's popular because we live in a culture of impatience, where instant gratification rules. PopSci allows people to get a dose of instant gratification and illusion of knowledge without doing any hard work.
