Where are all the low IQ people? Who are they? What do they do? How do they live?
>>7752144
they're shit posting on 4chan whilst sad NEET's respond in hopeful attempts to find meaning to their pathetic lifes

106 IQ(Checked it online tho) here. I don't want to live anymore. Are online tests dubious? Do I have any chance to succeed?
>>7752165
iq doesnt mean much when death is inevitable and our lifes are biological accidents
Why is smoking marijuana seen differently from smoking tobacco in terms of harm and benefits?
How do you quantify harm? Also, butane?
>>7750756
I'm guessing they took data based off of crimes/assaults where the offender was high, and probably recorded hospital/suicide/whatever data to record self-harm.
Marijuana is way more psychologically harmful than physically harmful though

If you're weak willed and easily succumb to addiction
What does /sci/ think of this mechanism? It is an hydraulic motor which I designed because the vane motor was too complex for me to build. The blue part is a stator and the yellow is the rotor. The water enters the gap between the rotor and stator next to the right pink slider and exits next to the left pink slider. Since there are two chambers opposite each other you can push the rotor on both sides. I did research on existing motors and this "balanced" property is highly desired because it doesn't stress the rotor and axle with unbalanced torque. As far as I...

Here is a vane pump in comparison, as you see there are much more moving parts.
Delete the thread and patent it you moron. Gid mone. Fug bishes.
So did you build a working prototype or planning too? Would be cool with a plexiglass plate on top.
What does /sci/ think of Richard Feynman?
>>7752842
If he's so smart, how come he's dead?
Checkmate, atheists!
I'm just a dopey freshman in physics, but my thoughts about him:
-He was a genius. Hard to argue against. He was a whiz at math (Putnam fellow, for Christ's sake) and his contributions to physics both added knowledge AND an understanding to the field of QCD. Not anyone can add mathematical formalism to field, but even less can do so in such a way that the formalism seems to make intuitive sense.
-He was a great teacher. What he did for academic physicists, he did for undergraduates. I've worked through a bit of the Feynman lectures, and they are...

Why are you still resisting the beauty that is String Theory?
>>7748478
Because it uses meme equations like 1+2+3+... = -1/12
>>7748495
What classifies an equation as a "meme equation"?

What is the difference between CE and CS?
Essentially, CE designs the hardware that runs computers (i.e. hard drive, ram, etc.) CS designs the software and programs to run on said hardware. Just a basic overview. First post on 4chan also, go anons
CS: software
CE: hardware

What's software engineering and how's it's different

I presume there are some aspiring neuroscientists or biologists here, even if they are a minority.
How painful is hanging oneself? How much time does it take for one to pass out?
My boyfriend committed suicide a couple weeks ago, I wish to know how much he suffered, if at all.
I have no background in neuroscience or biology and there is limited literature out there for obvious reasons, so I have no clue.
Also, consciousness and afterlife general if you wish.
I presume most of you do not believe in an afterlife, do you think anything we experience...

Depends on how it's done. If you just cut of circulation it takes a few seconds and then it's done

I mean the typical head and tie sort of way, I'm not sure of the specifics.
It wasn't a long-drop that snaps the neck if that's what you're asking.
Pressure was applied by his body, not by kneeling or anything of the sort.
Some sources I've read say thrashing and such go on for a couple minutes after the neck is suspended, which seems like a hell of a lot of time.
So event horizon is the point of no return, right? After that event light can't escape. So do we have any way to know what physics are going on beyond that point?

If We can't make any observation then all there is is theoretical math

A singularity of unknowable density. Essentially a massive amount of bosons all occupying the same quantum state with a mass of several suns to several billion suns.
Is there any known limit to how dense a blackhole can get?
How much has the taboo against tobacco (and thereby nicotine) hurt the progress of the sciences?
>>7737067
Not notably. A drug dependence won't hurt the progress of science, it'll hurt the progress of the dependent's science.
>>7737067
The taboo against amphetamine and cocaine may have harmed it more.
>>7737067
>taboo against drugs in general
Fixed. Everyone still thinks shit like ecstasy, cocaine and heroin are a boogeyman. When used in moderation, people can actually function normally on these drugs.
Can technology beat thermodynamics or will I die one day?
If I can only live to be a billion years old, I'd rather just kill myself now and get it over with.
Nobody reading this thread will live past the age of 120. A billion years is quite a stretch.
The thermodynamic limits of the universe are not the reason you will die.
>>7749709
When I become a computer why wouldn't I be able to live for a billion years?
What are you working on?
For the record, CS != Python programming. Try Operating Systems, Compiler Design, Category Theory, Computer Security, Computer Vision, Robotics, Natural Language Processing, Machine Learning, Game Theory, Functional Programming, Computability Theory, Databases, etc.
>>7734467
Undergrad focusing on machine learning/theoretical shit and discrete math here. I honestly hated cs and wanted to go full discrete math before I started taking courses on machine learning
Where does everyone download their papers from for free?
Good news everyone

What is your favourite programming language and why?
>>7738955
C
because I took a class on C and a class on Java for my EE degree and I liked C more.
C++
Fast and has many higher level features

Yet another fireworks show by the one and only Melonusk. I really want him to succeed and progress with SpaceX but I can't convince myself to believe that it won't get fragged into a thousand bits :^)

A farmer is building a CIRCULAR fence, but it is partially built touching the side of his house.
How to find the optimal ratio between the chord length and the fence length such that the area covered is maximal?
>>7746888
To clarify "a" is the chord length touching his house so there's no fence there.
I'm supposed to solve it in mathematica but there's gotta be an elegant solution to this.
just fucking build a fence, no math needed. you act like white people where the first to make pyramids.
