Let's say I just got shot in my leg (thigh, no bone). How do I fix my wound without going to the hospital, and without needing too many instruments and drugs? Do I have any chance to clean and close the wound without infections and whatnot?
>>8095966
no.

You know when he puts gun powder on that huge nasty cut on his throat then lights it up? Would that really work in any way?
Hi guys i'd like to share some of my lame undergrad simulations with you, I guess we could share some shit we did in this thread.
Be aware that my gifs will be pretty shitty cause I just learned how to do them.
Also they will be in portuguese because it is my main language.
The first one is a magnus effect simulation, the balls are exactly the same, except that the light blue ball has zero angular momentum while the dark one has non zero. Perspective is bad in this one.
not something I did

In this one I tried to recreate this situation

Just pretend there is a rope linking them like in the video. The mass that starts below has 80kg while the other ones 8kg if I remember well... There is no resistive force and the rope is not rolling on the rod. I tried to set the initial conditions similar to the ones in the video.
this one is a wave function spreading in a square barrier

Wow thats impressive, I really hope I have this much of free time if I ever get a job
What substitution would i use for
the integral of (Sec(x)^9)(tan(x)^3)
>>8095855
ah thanks
>>8095853
cos(x) = u
-sin(x)dx = du
sin^2(x) = 1 - cos^2(x)

Anyone have any recent research on the lasting effects of alcohol?
We all know extended periods of heavy drinking can lead to brain damage, and this damage can take years to be restored. What is heavy drinking though? A year of getting wasted every night? Or as little as a single week of extreme binging?
What about lighter drinking?
Is nightly red wine a myth?
Does having a single beer a night do anything harmful?
IQ?
There are studies that show a glass of wine a day is actually beneficial, so I'm sure alcohol, like almost every other edible substance, is healthy only in moderation.
I can only think of substances like lead or mercury that do damage to you without a lower limit on their concentration. These are substances that are not healthy in any amount. Alcohol is alright as long as its in moderation tho.

I know you were trying to make a point, but it did not answer my question. If someone had 5 drinks one night and never drank again. Does that person now have to wait a whole year for the effects to go away?
Is there a plant that grows fluid that can be turned into a lightable?

Anyone know anything about neuroscience here?
I took on a stressful job recently, so I started playing chess online in my spare time - 20 games a day, for two weeks. A few days ago I started getting splitting headaches when I tried to play chess. Last night I woke up at 4:00 am and my brain was on fire. I thought I was having an aneurysm. I could not stop thinking/dreaming about chess. Easily the worst headache I've ever had.
I know I need to take a break, but what causes this to happen?
>Anyone know anything about neuroscience here?
no. literally no one here does. you'll just get googled answers which you can easily find yourself.
stop being lazy.
>>8095632
I mostly did pharmacology/drug chemistry, but I had to take some neuroscience, I wouldn't say I really know it, though.
Anyway, this could be something like migraines (did you also notice a very heightened (to a painful degree) sensitivity to sights and sounds?). If not, it sounds like what is called a thunderclap headache (https://en.wikipedia.org/wiki/Thunderclap_headache). You need to go to a doctor now. Statistically, it probably isn't a subarachnoid hemorrhage (anyeurism bursting in your brain),...

i dont know anything technical, but I've heard that playing mental chess in excess can literally make you go insane. Google whoever has the record for most simultaneous games played mentally and you'll find some stuff on this.
I'm sure you get my point and how it's relevant.
Is it possible to scientifically determine the most attractive proportions of a human face?
Something something golden ratio.
The greeks solved this one long ago, friend.

What are some cancers and anti-cancers you know of?
I know that cigarettes and processed meats have been proven to cause cancer.
And I know that exercise and vegetable juice are anti-cancers.
Is there anything you would like to add to the list?
>>8095451
Even fit people can get cancer, anon.
Cancer is just a mutation, you can't anti-cancer anything. You can decrease your risk by not exposing yourself to certain mutagens, but mutagens will forever always be around you.
You can also increase the chances of getting cancer by ingesting or being around mutagens, which increased the chances of a cell mutating into an immortal hellspawn that wrecks havoc upon your entire body. The chances of cancer 'cure' is probably going to impossible without a better...

Google "known carcinogens"
>>8095482
it is an anti-cancer in that it reduces your risk. But increasing your intake of that anti-cancer to ridiculous levels doesn't make you cancer proof, no.
In science, everything is made by monkey men. Why are people so competent at some things but at the same time so utterly retarded?
I think the most maddening thing on Earth has to be anything academic that is constructed by "scientists" or similar animals.
For instance, algorithms, complexity theory, etc it is all done by utter morons I don't consider to be human.
look at how retarded this representation is.

muh fucking academics
monkeys
what do you consider yourself to be?
Why are monkeys so superior to humans in terms of strength and athleticism - to the point that your everyday primate can outperform world class athletes?
At what point during our evolution did it make sense to abandon such traits?
Yeah, monkeys and other primates are totally ruling the world with their big muscles

Wait, is this like the thing with ants?
"If an ant was as big as a human, they could lift a car!"
Cause that shit is pure bullshit.
An ant scaled to human size would collapse under it's own weight.
Fuck ants.
Are these things safe? Am I going to burn my house down?

Not an EE, but I can tell you what to google to research it on your own: ground vs neutral.

The OP pic has a ground tho, right? You unscrew the outlet plate and plug in the adapter with the screw in the blue bracket.
hello you smart autists this is /k/ how do railgun works and how can we make them fire cosmoline please translate this to american thank you
Discuss.
>>8095188
Basically they use electromagnetic fields to propel a projectile at high hypersonic velocites, due to the laws of physics this would produce a very strong recoil effect making them impractical as hand held weapons unless you like your arm being blown off. Still the overall damage is higher than a chemically propelled projectile.
>>8095193
>eletromagnetic fields
so why exactly isnt the gun firing at a constant rate? like it's a full auto thing?
i thought there was no on/off switch for magnets?
and how can it fire cosmoline?
serious question.
>>8095198
The entire point of the rail gun is to rapidly turn magnets on and off, so that the projectile is attracted forward by the magnets ahead of it but not attracted bacwards by the magnets behind it.

But this, though related to No Porn recovery, deserves its own thread.
Is it possible to alter your sexual preferences with drugs?
Apparently DeltaFosB is a protein associated with addiction formation, in food, sex, drugs, and gambling. It's triggered by overconsumption (e.g. ten tabs of porn) and accumulates with repeated overconsumption. So both the experience of the tabs and their content are tagged for future cravings.
How can I induce the accumulation of DeltaFosB?

Overkill is my middle name.
It's come to my attention that a hormone called Vasopressin influences male sexual decisiveness.
It's that very distinctive "zero-ing in" feeling just before the clothes come off, and it comes in a nasal spray!
If I took vasopressin (or its synthetic, desmopressin) and a dopamine stimulator before a sexual encounter, I predict the encounter would take place on the counter, or possibly kitchen table. It sounds like the perfect cocktail for a studly demeanour.
What does /sci/ think of this UFO footage?
https://www.youtube.com/watch?v=yGIH7ufiBII
The full film with frame by frame analysis is at 2:45
You all always say that you can't take UFOs seriously because there's no footage, well there's loads but being 2016 and all it's mostly fake which is why I never post it. However this one was shot in 1950 and analyzed by many organizations over the years

If you don't care for explaining the unknown why are you doing science?
May I also add that this is the USAF Captain that redacted the original explanation

Bear in mind that this guy was paid by the government to explain away UFOs as "nothing"
How would life change if we would know that in 200 years with 100% certainty the universe would cease to exist?
