Orgasms While on Amphetamines

/sci/ I had an experience a little bit ago, and I want to know the biology behind it. Why do you cum like a .50 rifle discharged when you masturbate on methamphetamine or adderall? Literally, it's so intense my vision went semi black. My cock was so hard it hurt. My PC muscles were spasming so hard i thought i ripped something. I had 10x as much semen too. Like my entire prostate drained out of my dick. I've never felt anything better in my life, not even snorting oxycontin. This is how it went basically. >smoking meth for the first time, usually snort it >dat rush.jpg >take massive hit, cock spontaneously gets hard for some reason >higher than I've ever been >suddenly, incredibly horny >quickly go to computer and find close-up porn so i can see penetration and imagine my cock going into a raw cunt >3 hours later about to cum with 40 tabs open >OH SWEET JESUS IM CUMMING FUUUUUUUUUUUUUCCCCCCCCCCK >actually make a loud noise I can't control and i start shaking and I accidently knock a glass off my desk and it hits the floor and breaks. >feeling too good to give a shit, massive load shot onto my neck and chair >mom opens door as I lay there covered in cum with porn on the screen and meth pipe on desk as my cock is still twitching >I have one week to find a place to live and then im kicked out

Quick question guys: Prove the assertion in Example 19 that the set {1, 2, . . . , n ? 1} is a group under mul- tiplication modulo n if and only if n is prime. I did forward, but I'm having trouble showing that if it's prime then it's a group. Any ideas?

What jobs in science allow for international work/travel? I'm taking Chinese because I'm thinking about engineering and many of the engineers I've talked to at college fairs strongly recommend learning Mandarin for engineering. I also am reasonably fluent with Spanish. Pic unrelated.

Hey, sciducks a /sp/artan needs some help with his trig homework. I know i'm supposed to use a calculator to solve these but I don't know exactly how to plug them in. It should be pretty easy. anyway thanks in advance for the help.

Can anyone point me in the direction of a video clip of a real (not staged) psychoanalytic therapy session? Or any video of some sort of normal psychiatry, psychology, etc session? No psychopaths please I'm just interested in what goes on in a normal therapy session. Thanks.

anybody know how to get the net ionic equation for this? ** pic unrelated ** 4HNO3(aq) + Cu(s) => Cu(NO3)2(aq) +2NO2(g) +2H2O(aq)

1s22s22p63s23p63d5 is apparently the electron configuration of an Fe+3 ion. I thought 4s filled up before 3d, so wouldn't it be 1s22s22p63s23p64s23d3?

Let's say technology is invented that could shift our entire perception of reality(feel,touch,smell,motor control,etc...) to a virtual computer generated one, with the ability to log out and return to the real world when you wish. With literally unlimited funds(limited by disk space) to create a digital laboratory, what type of setup would your 'digital' lab have? I would have floating blackboards all over, ready for utilization to learn advanced mathematics.

Hey I will be declaring my major soon and havn't had to do any coursework in particular to any of the disciplines I am considering. How does EECS compare with Math/Physics? I have a passion for both but which one is more valuable? Image unrelated

I think my girlfriend may be legally retarded. She told me she was having problems with 10th-grade chemistry and wanted me to explain this shit to her. I tried it the "normal" way, i.e. how you learn it in class. She didn't get it. Okay, that's fine. I understand that some people need to be able to visualize these kind of things in order to understand. So I went ahead and fucking made a puzzle with her, like in pic related. I cut out pieces with 1-3 notches / bits that would fi in the notches, according to their oxidation state. I explained to her that (anorganic) acids always consist of n H+ ions and "a half salt molecule" with an oxidation state of (-n), while (anorganic) bases consist of n OH- ions and "a half salt molecule" with an oxidation state of n (in simpler terms, of course). I then explained to her that mixing an acid and a base would result in the base's OH- ions and the acid's H+ ions forming H2O (water) molecules while the rest of the ions would form a salt. All that I visualized by acting out the according actions with my puzzle pieces. And she didn't fucking get it. What's so hard about understanding TAKE AB AND XY SPLIT UP, YOU GET A+, B-, X+, Y- + AND - COMBINE AGAIN GET AY, XB

Biomechanical thread i want to start a top secret research center that focus mainly on biomechanical. So i can take the human brain into mechanical that run a small nuke as power source. then i can send it into space to do the exploration in deep space so we won't worry about dying.. picture related that is what i want to work on it.

Let's see if /sci/ can do this Solve y'+y^2+(sin(2x))y=cos(2x), where y=y(x) Which is a ricatti equation, that can be transformed into w''+sin(2x)w'-cos(2x)w=0 If you're wondering where i got this it's from Bender and Orszag's Asymptotic methods and Perturbation theory

Draw (2R,3S) 2,3-DiBromohexane I feel like both of these Fischer projections are correct. Can anyone help me out? Is it common to be able to draw them in more than one way? Thanks in advance
