Sup /chem/,

I'm taking general physics 2 this semester and I have the same professor I had for physics 1. Now it's just algebra-based, and I've been through calculus, so I was able to breeze through Newtonian mechanics and all that. However this semester is about electromagnetism, circuits, and optics. All topics I have zero exposure to. Now the professor is new to teaching at the college level, his experience is teaching middle-schoolers. He is very (obliviously) condescending and talks to his class of adults like they are 12. He constantly makes sexist or racist jokes (but on the fence enough to not get in trouble) and is always ranting about his personal life or past experiences. When he finally does an actual problem on the board he always struggles with basic spelling and arithmetic, and often fundamentally misunderstands the physics concept he is trying to teach. Several times last semester I had to quietly approach him after class and explain how everything he lectured that day was flawed and the next lecture he would try to fix his fuckup but he ended up just giving everyone lots of freebies on the exams.

My concern is that in this new semester of material I will not get a good exposure or foundation in these topics and might be lost in future courses. Especially electricity and circuits, I really want to learn more about that. I am worried he will teach me some fundamental concepts backward or something. Other than pre-reading the text before class what would you guys recommend to get through this course when the professor is a complete idiot and in my opinion not qualified?

Thread premise stolen from Bluelight. Post molecules you think would make promising drugs. They can be totally novel, or known substances that, for whatever reason (synthetic difficulty, obscurity, poor effects) have never hit the recreational market. Relevant links (literature papers, PiHKAL, trip reports, syntheses, etc.) encouraged.

I’ll start with this one. This molecule is 3-methoxy-4-propoxyamphetamine (“POMA”). It’s active as a mildly psychedelic stimulant and mood elevator. Someone has already synthesized and trialed this compound; you can read the full report here (https://bitnest.netfirms.com/external.php?id=%25087%253B%250B9%2501%2509Czzy%2505)

Not terribly exciting, but interesting all the same. He starts with clove oil (containing eugenol), but an alternative route would be to start with vanillin (much cheaper than clove oil), O-propylate, condense with nitroethane, and reduce.

>(with 140 mg) There were not the color changes of mescaline there, but certainly a good humor and an over-appreciation of jokes. The images behind the eyes were remarkable and tied in with the music, and I became annoyed at other people's conversations that got in the way. I was out of it in eight hours. I would equate this to 300 or 350 milligrams of mescaline and I rather think that I would prefer the latter.

Does anyone know of any good documentaries about how different drugs effect the brain? Not scare factor "durgs r bad", I'm looking for something about the chemical reactions in an unbiased setting. Something that gets deep into, from ingestion to end of effect, how it metabolises, stores in the body, what endorphins and neurotransmitters things release and what effect that has.

It's a shot in the dark, but drug neurochemistry is an odd hobby/interest of mine and I figure this might be one of the most niche forums that I could ask.

I want to be a scientist. I want to research and be active and feel like I'm actually getting something done. What sciencey things can I do in my free time that will actually bring me closer to these goals?

I look things up on wikipedia constantly. I regularly check on a site that summarizes recent scientific papers. Isn't there something more that I can be doing while waiting for the GRE to come around that would help me reach my goals?

I work full time in a microbiology lab, but working for a company isn't the same as working for a cause. What science related things do you do? For a living or for enjoyment and fulfillment or just to kill time? What science websites do you look at? What science hobbies do you have?

That's just entertainment, to contribute to science you'd actually have to do all the hard work of figuring out the intricacies of whatever interests you, not just reading about summaries of what other people have achieved.

To get closer to your goals probably more education would be good.

Although I was interested in identifying mushrooms, I wasn't very interested in microbio until I went to the library one day with nothing particular in my mind and ended up leaving with pic related.
I got my BS in chemistry, and while in school participated in ecology research and an ecology internship. I focused on organic chemistry and took a good number of biology classes, but never microbiology. The lab I work for now basically only hired me because I was interested in fungi, had worked with fungi before (minimally), had used a microscope before (again minimally), and grew mushrooms in my own time. Please ask if you have other questions about it though. I'd love to encourage any discussion on /chem/


I want to learn and apply my knowledge to help the environment and the common man. I'll probably go to grad school for ecology but I'm still uncertain.

I just want to be like my hero Carl.

Mercury Storage by Polly Pockman - Thu, 04 Jan 2018 19:11:36 EST ID:UniRKo9r No.78958 Ignore Report Reply Quick Reply

sup /chem/

I have a small elements collection and I needed to know about the storage of a small amount of mercury...

I have (attached) glass vial bought from Hobby Lobby for like 2$. I am wondering if it would hold a small amount of mercury. We're talking 5mL maximum, probably less (may fill up an inch of the bottom of the vial). The top glass cork will be wrapped with a few layers of parafilm from my lab. It will be on a sort of "display" shelf, not behind any glass but out of reach to be knocked over. I am more worried about the vapors that could possibly form over time than any spillage.

Any input would be appreciated,
Thanks

and seal the ends using a propane torch. look up "ampoule sealing"

That way you can still play around with the mercury in a fun size. When not in use, wrap the test tube in a piece of aluminum foil coated bubble wrap insert. If the mercury escapes, it'll go right into the aluminum which will make it less hazardous as it's a mercury capture mechanism. For spills, use powdered sulfur. You can buy that on ebay in like 100g quantities.

Thank you for the replies. I ordered myself some of the shown test tubes and am not sure how long they will take to arrive to me. I currently have a very small amount (barley covering the bottom) held in the glassware shown, with several layers of parafilm and it is being kept outside. I believe this should sufficiently hold until I am able to make ampules.

organic chemistry will teach you that bromination is a method to turn cyclohexene into benzene
industrial chemistry will teach you that method is only valid up to 5g on a lab scale and impractical for real life

wokest brain organic chemistry will tell you that since cannabinol has no enantiomers, you can do a very, very easy full synthesis from industrial chemicals like we do with 90% of all the drugs we have. if you want CBN on a large scale, total synthesis is probably the way to go (unlike with THC that has multiple chiral centers)

ancap chemistry tells you to sell your THC distillate and buy CBN with your money. or you can use THC to buy bitcoins and then lose all your money instead. woke machine broke

I actually miss A Wizard too until Vehk chased him off and we got /420/ to ban the IP addresses until all his VPNs expired. Then when every post at him was hostile, he finally quit. He was only really bad on /med/.

Totally forgot /tesla/ was a thing. Same thing with /diy/. /chem/ i'm here because it's a containment thread revolving around Vehk, Press, and high kids from /weed/ that get spooped about quantum physics.

I wanna discuss opiate science but I'd much rather just do that in real life. Green Fox was helpful, too. But anyone without drugs as a tether eventually ends up leaving this god-forsaken place. Too bad I'll probably need opiates for the rest of my life (even if it's only a few times every month). Realistically, I could start posting good threads about opiate science and other drug science, but I'd much rather just talk to people IRL about that and who can give insight into my orgo questions and techniques.

In any case, you can call me son if you want. I used to go on the /dis/ or /weed/ much more and didn't decide posting on /chem/ until I tripped up. Not sure how long ago that was (and don't really want to know). Maybe a /tesla/ /chem/ merge would be helpful.

I would agree with this. Decomposition, denaturation, and bacterial/fungal consumption would render blood into basic chemicals. As mentioned, full of potassium salts along with sodium/chloride/iron/copper/etc salts. The proteins would be be broken down into various organic chemicals or utilized by the local flora. Any saccharides floating around in the blood would be consumed almost immediately; nature likes sugars.

This is just my own speculation.
