What are some good studies on the problem of addiction? Lack of will power, self-control... psychological dependency?
What you described is compulsion. Addiction is chemical dependence.
>>7964943
Not entirely, there are social/environmental factors as strong as the chemical ones
>>7964943
Yes, that too.
Any Biochem double majors here? I want to go into Neuroscience and so I'm heavily considering a Biochem + Psychology double major.
I think that a biological science + social science combo would be nice because I could actually get a good job and be prepared for medical school with Biochem, but then also have a better understanding of the mind and be a bit more socially well-rounded with Psych.
Other than Psychology I'm not sure. I kind of want to minor in Economics because I've been told that's an all-around good thing to have an understanding...

Elaborate on why this is a bad idea?

VR is finally here. I never thought it would be but it happened.
What will be the next "future technology" to finally arrive (as in, a polished worthwhile consumer product rather than just a stunt/demo)
Personal humanoid home robots? Personal VTOL? A lab on Mars? An underwater colony? Cities in Antarctica? Consumer gene editing?
>>7964779
What the fuck? How old are you? This technology has existed for decades, it just wasn't commercialized successfully.
>>7964782
Read the post more carefully. This time do not just skim and take away the gist, but pay attention to qualifiers.
>>7964779
>Personal VTOL
People have been able to buy helicopters for decades. Hell, a Bell 47G was only 52k new inc engines
Hey /sci/, I've got a test tomorrow in Modern Algebra and I'm going through some problems. Are there any mathematicians out there that can explain how you factor x^3+2 in Z3[x]?
>>7964603
just try shit out
by inspection this looks like 1 -3 3 -1
if this hint isnt enough then you're fucked
>>7964606
I'm probably fucked, but oh well I'll keep trying things. Thanks for the hint.
>>7964603
There's literally 3 elements you have to check as roots, what are you stuck on?
So if males tend to be stronger would females be more agile because they're smaller? What advantages do the sexes have over each other?
>>7951754
life isn't an MMO faggot.
Males are more intelligent than females.
Deal with it
>>7951756
What do you mean?
well?
Radians. Degrees is just base 60 autism and should only be kept in seconds.
Radians because series expansions.
>>7964321
I use degrees when constructing frames and what not because the numbers are easier and I use radians when analyzing rotational motion because it makes the calculus easier.
What return percentage per year would this be?
The way I know of:
153,000,000 subtract 13,600=152,986,400. 152,986,400 divided by 13,600=11,249. 11,249*100=1,124,900.
1,124,900 divided by 8=140,612.5% per year.
Right or wrong?
If right, why do so many people on various sites calculate it as 220% annually? Which is right? How could someone come up with 220%?
>>7963540
Also, why does 13,600 times 2.20 for eight years come out to 7,463,118 on a calculator?
>>7963549
Bump
>>7963540
I would do it:
153000000-13600=152986400
152986400/13600=11249
(1+p)^8=11249
(1+p)=3.209
p=2.209
which is approx. 220%
Could you suggest me good graphing programms?

batch and minesweeper are bretty gud programs
>>7963347
depends, what do you want to do, mate?
Is depression actually real or is it just an excuse for lazy people?
>>7959358
it's both
>>7959358
Yes, depression is real and has been written about since humans have been writing.
>>7959390
But is the illness itself actually real or is it just people needing to stop being whiney cunts
Why do people think calculus is hard?
Low IQ brainlets
>>7953490
>brainlets
keep your shitty memes to yourself.
>>7953492
Was I talking to you ?
OP had a legitimate question and I answered him.
Tried to calculate this and got a result ten times higher, 62.8 meters.
Am I retarded or is Randall really a hack fraud?
the answer is clearly 2*pi you asshat
reas your fucking photo
Op clearly failed basic algebra.
>>7964764
Try and calculate it yourself instead of just trusting what the hack is writing, you simpleton.
how is it that you experience the world as a human, and not say, an Artificial Intelligence created by scientists, or another animal species.
think about how that is the case
>>7964695
ultimately it goes back to the big bang, and how it came to be. hard to answer the question
>>7964695
The question makes no sense. If "you" were an AI or a non-human, you wouldn't be "you". It's not like your soul is floating around and it goes into a random fetus. "You" are just the result of many many many many many many reactions. Flip a coin ten times. How is it that the specific pattern you got occurred when there are 2^10 possible patterns? It just happened that way and it's not very mysterious or shocking is it?
How is scientific literacy in your country?
>>7964602
transforming kinetic energy from wind into electric energy for other uses does change how the wind moves. have you done the math to know using it for 100% of our electricity wouldn't have an effect?
>>7964614
any change in wind patterns (not in atmosphere) seems trivial to celestial mechanics
also the guy linked a satire (think 'the onion' but for science) institute as his source
any physicists wanna pitch in?
>>7964614
Yeah Brazilians aren't particularly bright, what bothers me more is how smug that retard is.
People who don't know they are retarded are dangerous.
Any aeronautical engineering fags out there?
Can this fly?
Variable forward swept wing.
>>7964549
>can this fly
>is clearly flying in the picture
gee bill
>>7964549
General wing surface area looks like it'd be fine, looks like it'd flip shit if you put any kind of roll on it though. Yaw seems like it would be finnicky as fuck in the early MET, but I'm guessing it'd stabilize-ish after awhile.
That's a big ass intake though, and I can't tell if it's mirrored or not.
Seems like a huge waste of drag surface if it's just a big-ass ram scoop. It's a bit odd for a normal intake, though.
>>7964549
no it can not fly
i recommend the people in that car to jump off now
