tips on how to ace advanced organic chemistry final? polar felkin-anh, diastereoselective Aldol, allylation, [3+3] cycloaddns, hydroboration etc.
went through everything multiple times but lack a stack of 'exercises' because that's what really hammers the stuff in. searching for publications and rationalizing the outcome on my own seems too overkill time wise, so no idea where I should really get practice from to be able to apply the concepts of conformational analysis in harder settings
>>7787494 Wow, didn't expect an actually helpful answer this fast! Thanks, the lecture notes Approach seems very interesting. Currently going through http://onlinelibrary.wiley.com/book/10.1002/9780470199053
seems really good as the contents were literally what we did
only problem is that the exam will be 5 pretty demanding problems in 1 hour, so I'll have recognize shit immediately or I'll be fucked
Given that mental illness represents a tangible defect in the functioning of the mind, does it not stand to reason that we've evolved some mechanism of recovering from these illnesses, since we the body has regulatory mechanisms which attempt to deal with most of the other illnesses?
Could mental health practitioners achieve better results if they knew about said mechanisms and could work to maximise their effect?
>>7787371 No, but the body immediately floods the site with clotting agents and immune vectors to minimise further risks, eventually turning the wound into scar tissue for structural integrity and to keep bacteria and shit out.
I love to pick at my submandibular lymph nodes (The ones behind your jaw). I do this very frequently, since it feels like a testicle (If you're a dude and like to play around with your balls, you know what I mean).
I took engineering in uni and it felt like we did a decent chunk of math throughout. Not anywhere near the real math degrees, but we had some decent fundamentals down.
I graduated half a decade ago and I've been working a dead end job where I use nothing I learned at school
I just recently came across a problem where I needed to get the position of something given velocity, acceleration and time. That's straight up high school stuff, and its one of the basic kinematic equations for uniform acceleration.

>but the pdf of it I just downloaded is ~860 pages, so that probably doesn't fit the 'compressed/ refresher' description
Well if its just one book thats pretty good desu. What I meant was more like, I don't want to look up each of my courses, get a similar textbook (or just find the original in my garage if I still have it) and work through things that way
>>7787209 >Are you all able to quickly spit out the really basic stuff you learned in highschool and university ?
After 18 years in industry, most of my colleagues that I've worked with can't. Hell, some of them that were particularly weak couldn't remember that stuff a year after graduating. I can (mostly) and it really impresses people.

What the fuck is wrong with the US education system? >every school having different standards of GPA >taking some shitty multiple choice test to decide where you'll be >can take as many as possible, rewarding people who can go for tuition and spam tests like nobody's business >people with no money fuckin just lose out Unlike the UK, Where >A levels always test what you learn in school >open...

>>7787205 US uni admissions are almost pridefully antimeritocratic. Standardized tests aren't as influential or as useless as you think, though. The SAT is a fairly good measure of reasoning ability, and many schools here are now "test-optional."
The issue of grades is where it really fucks up big. Especially in humanities classes. Look at an IB english rubric. Take time to really appreciate the level of ambiguity and amount of "professional discretion" assessing someone's work takes. Now imagine none of your papers are eternally moderated, that your one teacher is the first and final authority on what you score, and that the rubric itself has been replaced with one -the teacher wrote herself- to include as much discretionary power as possible so she may block students with whom she disagrees or ones she dislikes from top universities with artificially low grades and give out artificially high grades to students she likes, agrees with, or is successfully manipulated by. You have imagined American high school.
I shit you not, I even got this treatment in math. One test question asked to find lim x->0 of sin(x), so I wrote "sine is continuous on R. By the def. of continuity, lim x->0 sin(x)=sin(0)=0" and got no points. Turns out I "hadn't shown my work" because his markscheme explicitly said I had to say sin(x) "gets closer and closer to 0 as x gets closer and closer to zero." Which, call me crazy, seems precisely a verbal restatement of the equality I wrote down after my actual fucking argument. And yes, I raised the issue very respectfully with him. He gave me the runaround for a good fifteen minutes and made it clear he wouldn't correct my score. There were about a hundred of these landmines throughout the course, and he was much more sympathetic when they hit certain people.
Now you fill me in on how UK uni admissions, offers, predicted scores, etc work. Is whether you get a spot just based on your A-level results, are there other (exploitable) factors?
Hello /sci/, since you (or /lit/) are considered the genius tier of 4chins, I bring my question to you. What is the most up to date philosophical equivalent of Newton's (or Whitehead/Russel's) Principia? I'm looking to read THE book on philosophy no matter how long it takes me, but I'm not familiar with any modern philosophers. Bonus if it involves mathematics/science, but I'm looking for something along the lines of the ultimate book of knowledge avaialble to modern man. >i'll ask /lit/ too to avoid bias
The problem is in how you're wording your question OP.
Newton just did some infinitesimal calculations of motion and defined what a force was + astronomy. He wasn't even recognized until 100s of years later. Decarte was more popular with his theory of vortices, but people were like 'Oh shit, Newton's better' in 1800's.
My guess is that you want to learn Logic, because that's the underpinning of any argument presented for Metaphysics, Aesthetics, Ethics, etc.
Hello fellow anons. Im interested to see how many of you are productive without some form of drugs be it caffeine, weed, alcohol, nicotine, etc. etc. Do you find yourself more productive under the influence of these? Have you tried to be productive without them? What was the result?
>"State-dependent memory, or state-dependent learning is the phenomenon through which memory retrieval is most efficient when an individual is in the same state of consciousness as they were when the memory was formed. The term is often used to describe memory retrieval while in states of consciousness produced by psychoactive drugs – most commonly, alcohol, but has implications for mood or non-substance induced states of consciousness as well."
>>7787100 Yeah, I'm much more productive while on a stimulant (usually an amphetamine derivative), however, I don't want to get in the habit of using them often like I've seen many of my stupid straight-edge-now-turned-addie-fiend high school friends do when they hit college. Actually I'm just thinking of one guy in particular lol
I use them to study twice a year.
I don't drink coffee or smoke usually. I use cannabis every other day but that's just to relax at night. I drink about... Comment too long. Click here to view the full text.
What is /sci/'s opinion of Data Science? I work in claims analytics for an insurance company and they're flooding our department with money to buy data from vendors. It's like executives got sold on big data from consultants or something. As far as I can tell it's just statistics + exploiting massive computation power.
