What profession do you think has the most intelligent individuals /sci/? I'm in medicine and I can safely tell you most of these people are completely fucking retarded outside of anything that has to do with it. Hell, alot of them are completely retarded in things that have to do with medicine. The classes are structured to pass standardized exams that are written by old fucks from 80 years ago on diseases so rare they might as well not exist. 80% of all medical problems can be solved by eating right and exercise and 10% are so serious the best they can do is try to add a few years onto life using drugs they're not even sure of the mechanisms of. But behold the wonders of a free market! I've gone way off track ...

Any cramming tips? I have a calculus test tomorrow, and I started studying today. Didn't really get much studying done and now I need to cram. Any tips? Calculus I at the University of Illinois at Urbana-Champaign btw, if it matters.

Why all the hate for Computer Science on this board? It seems to be dominating the job market these days. Everything is all about mobile apps, tech startups, and data.

sup /sci/ what do you think about the use of math and statistical inference in economics. Is enough to make it a science?

I'm growing psilocybin mushrooms and I'm using the rye grain method. Unfortunately, I went out of town for a week and neglected to have someone shake them up. I now have jars that consist of solid cakes. Is there any way to salvage this or are my fully colonized jars worthless now?

Questions I need answered to increase the level of discourse I can have with my friends on the nature of the universe: >What proofs are there that mass and energy exist as probability distributions instead of discrete particles? >What dictates that an electron go from existing as a probability distribution to existing in a particular place and having a particular effect on other mass and energy >What dictates that an electron will revert back to existing as a probability distribution? Pic related because maladjusted teens are always related on 4chan.

Organic Chem question here Give me a run down; why can a hydrazone be used in a wolff kishner reaction but not a oxime? only difference is between the OH and the NH2. Does it make that much of a difference? >inb4 stupid question

Hey /sci/, why is physics always said to be the hardest of any of the sciences? I thought the goal of physicists was to make this world less complex, and easier to understand, but instead it is just more complicated than ever. Are we just not done with physics? Is there so much more to discover that will finally make everything clear?

Sci what are your thoughts on adderal, dextroamphetamines, and vivance. I had a chance to try dextroamphetamine for the first time and everything seemed just so intuitive to me and i was actually capable of doing stuff on time, while normally i stay up the entire night and start hw/studying an hour or 2 before class. Anyone else have experience with them and would it be a good idea to get myself a script for them. I sit in class and get nothing out of it because i just can't focus, but on dextroamphetamine i was able to focus and actually understand the information.

http://www.ted.com/talks/andres_lozano_parkinson_s_depression_and_the_switch_that_might_turn_them_off.html Pretty amazing. I'm a pleb, like to think I'm not, but am pretty sure that's the reality of it. Was wondering if somebody could help tweak my upcoming statement and help me rationalize it. Why wouldn't the creators of this technology be able to use this device on themselves to radically improve their ambition and memory to improve the device? Thanks in advance for any replies

Question. What's the difference between the easy chemistry (in my college its called fundamentals of chemistry) and general chemistry, beside the obvious 2 semester and lab required by gen chem. Does it require a higher level of math? On a scale of 1-10 of hardness, where would you rank fundamental of chem and general chem? I'm currently taking fundamentals for my major (nursing) but once I want to go to graduate school I'll need to take gen chem 1 & 2. Thanks in advance.

I've been doing some rudimentary research out of curiosity, but... Is it true current mainstream fuel sources are estimated to be depleted within half a century? Things like oil, coal, and the like? This is accounting for the fact if current demand continues to grow with population increases. And looking at some other figures and graphics, other materials range anywhere from 15 years to another 60 years of production. Is this all true? How is the Earth going to sustain the lifestyle humans have now if resources are going to run out within the century?

OK pop quiz /sci/ Linearize a quadratic equation (y=ax^2+bx+c) I bet half of you can't even do this babby math. You fakers come here and become shakers.

I'm doing a research project for school. I just need help calculating something. How do I calculate a cubic foot of propane gas burning at 160 degrees Fahrenheit? What exactly am I calculating? Is it the temperature at which fire burns through gas?
