Orgasms While on Amphetamines

30 more posts in this thread. [Missing image file: 1282005351907.png]
/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

Complimentation Groups

5 more posts in this thread. [Missing image file: complimentation.jpg]
>Complementation tests of the recessive a mutant genes a through f produced the data in the accompanying matrix. The circles represent missing data. Assuming that all of the missing mutant combinations would yield data consistent with the entries that are known, complete the table by filling each circle with a + or - as needed. - signs mean the genes fail to compliment, which means the mutation is on the same gene Lost as fuck. Does it mean that when ever you see a minus sign, the genes have a mutation at the same spot, and shit doesn't work?

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?

How much harder is chemical engineering compared to chemistry? I'm almost done with my chemistry BA but with the lack of jobs, I'm transferring to a chemical eng. program. I have 0 work ethics and rely entirely on Focalin to get shit done. The tolerance issue is lurking beneath the surface. I didn't consider engineering until I got diagnosed with ADD and given a prescription this year. I noticed some courses like Transport Phenomena, Heat Transfer, Reactor Design, etc. that's not included in the chemistry curriculum. How tough are they? I thought physics 2 was a lot harder than organic chemistry, which was pretty easy.

/sci/ what is your absolute biggest ambitions in life? Mine is to recreate eugene podkletnov's experiment on rotating superconductors and if they are proven to be correct I would like to learn everything about them. You can never know for sure until you do it yourself, anyway /sci/ what is your absolute biggest ambition in life?

Knowledge Issue of Death

6 more posts in this thread. [Missing image file: partyhat1.jpg]
Hi there guys, this is my first time posting to /sci but i feel this would be the best place to evoke a good response and debate if i dare say so. Anyways, for my Theory of Knowledge class we were asked to come up with a presentation of a knowledge issue (dont ask me to define what that is because I'm not sure I could even properly explain, especially over the interweb). After some thought I came up with the mourning of the dead as my issue. Why do we mourn? I personally believe we should celebrate the feats of the person. Also those who are religious would be selfish to miss the person since they would have (hopefully) ascended to the glorious afterlife denoted by most religions. I'm just putting this into the open to see if I can get any examples or ideas to build off of. Hopefully it does well and I appreciate the help in advance. Thanks! TL:DR Why do we mourn the dead as opposed to celebrate it?

Logic Games

11 more posts in this thread. [Missing image file: judiciary_126_2nd_try.jpg]
I'm looking for free online logic games. I love Jahooma's logic box and Manufactoria. Both have some hard levels, and it's fun to try to minimize the parts count after you find a working solution. I tried Tile Factory, and the first 5 or 6 levels were boring so I quit. Does anyone know if it gets challenging later on? Another decent game is light-Bot; it doesn't have many levels, and only one is actually challenging. So, does anyone know of other games similar to these? pic related - it's one of the tougher levels of manufactoria.

Were any of you guys really awful at math once? I've been struggling with it since coming out of my mother. When I see numbers, I just phase out. I do have ADHD, but I just absorb chemistry like a sponge so I don't think it's that. It makes me sad because I want to major in biochemistry.

You have 14 numbers. They can all be a 1 or a 0. There can't be 4 adjacent 1's or 0's. How many combinations can you make.

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